Pls mark my answer as brainliest :)The outside of this set of four cubic blocks with no space between blocks is painted. What is the number of painted square faces?
Answer:
18
Step-by-step explanation:
There would be four faces on the top, left, bottom, and right. That equals 16. (4x4)
There would also 1 on each end, so you have to add 2. That equal 18.
This is assuming you paint the faces on the bottom. If you didn’t, the answer would be 14. (But it doesn’t say not to paint them.)

A party mix is made by adding nuts that sell for $2.50 per kg to a cereal mixture that sells for $1 per kg. How much of each should be added to obtain 60 kg of a mix
that will sell for $1.40 per kg?
1. The amount of nuts is ____kg and cereal mixture is ____ kg to obtain 60 kg of a mix that will sell for $1.40 per kg.
Answer:
The amount of nuts is 16 kg and cereal mixture is 44 kg to obtain 60 kg of a mix that will sell for $1.40 per kg
Step-by-step explanation:
Let
x=nuts at $2.50 per kg
y=cereal at $1 per kg
x+y=60 kg (1)
2.50x+y=1.40(60) (2)
From (1)
x=60-y
Substitute x=60-y into (2)
2.50x+y=1.40(60)
2.50(60-y)+y=84
150-2.5y+y=84
-1.5y=84-150
-1.5y=-66
Divide both sides by -1.5
y=44 kg
Substitute y=44 into (1)
x+y=60
x+44=60
x=60-44
=16
x=16 kg

Below are the distances that each of Davi the Dragon Keeper's four dragons can blow fire (in meters). 0.9, 0.5, 0.3, 1.1. Find the mean absolute deviation (MAD) of the data set.
Answer:
Step-by-step explanation:
MAD is simply the average distance that all of the numbers in your data set are from the mean. Your first step is to put your data in order, then determine the mean. Let’s look at this data set:0.3, 0.5, 0.9, 1.1
The mean of this data set is 0.7Starting with the lower extreme, and checking every number in your data set, determine how far each number is from the mean. First, put the numbers in numerical order, from least to greatest. Determine the distance each number is from 0.7. 0.3=0.40.5=0.20.9=0.21.1=0.4Add up all of the distances. Total distance from the mean (12) ÷ 4 numbers in our data set = a mean absolute deviation of 3.I added a PowerPoint that I made so that if you didn't understand it you could read off of it.
Answer:
[tex]0.3[/tex] - written in [tex]2/14/2021[/tex]
Step-by-step explanation:
The answer is [tex]0.3[/tex] because, [tex]\frac{0.9+0.5+0.3+1.1}{4} =\frac{2.8}{4} =0.7[/tex], so [tex]0.7[/tex] is the mean. After having found the mean, we have to subtract [tex]0.7[/tex] from the numbers, or the numbers from [tex]0.7[/tex]:
Data Point | Distance from the mean
[tex]0.9[/tex] | [tex]0.9-0.7=0.2[/tex]
[tex]0.5[/tex] | [tex]0.7-0.5=0.2[/tex]
[tex]0.3[/tex] | [tex]0.7-0.3=0.4[/tex]
[tex]1.1[/tex] | [tex]1.1-0.7=0.4[/tex]
After finding out the Distance from the mean we'll use their sums and add them all up: [tex]0.2+0.2+0.4+0.4[/tex], then divide them by [tex]4[/tex] because there are [tex]4[/tex] numbers combined together: [tex]\frac{0.2+0.2+0.4+0.4}{4}=\frac{1.2}{4}=0.3[/tex].
So that's why the answer is [tex]0.3[/tex] (Happy Valentines Day!)
Which number is an irrational numbe?
Answer:
Option D
Step-by-step explanation:
=> [tex]\sqrt[3]{16}[/tex] is an irrational number because it cannot be written in the form of [tex]\frac{p}{q}[/tex] which is one of the most important characteristics of rational number.
=> The simplified form of [tex]\sqrt[3]{16}[/tex] is [tex]16 ^{1/3[/tex].
Answer:

A rectangle is graphed on the coordinate grid.
Which represents the equation of the side that is parallel to sider?
y=-X+9
y=-x+ 5
y=x-3
y= X+3
Let’s see if I can help you :)!
With two points you can define a line.
So, the line parallel to s is q, which has these two pointS: (3,6) and (6,3)
There are different ways to get the line. For instance, this one:
Y = a*x+b
a = slope = difference_y/difference_x = (3-6)/(6-3) = -1,
y = -x + b,
Now use any point, say (3,6) to get b:
6 = -3+b-> b - 9.
Line is y = -x + 9,
It checks out in the other point: (6,3) —> 3 = -6+9 = 3. Good.
Other method:
y-y2 = a*(x-x2), where (x2,y2) is one of the two points and a is the slope as defined before.

A bag of marbles can be shared equally among 3,
or 6 students with none left over. What's the least
amount of marbles that can be in the bag?
If there are 150 people born in the world every
minute; how many are bom every Hour? Day?
Year?
Answer:
1) 3 marbles
2) The number of people born every hour is 9000 people
The number of people born every day is 216,000 people
The number of people born every year = 78,840,000 people
Step-by-step explanation:
1) The given information are;
The number of students = 3 or 6
Amount of marbles remaining after sharing = None
Least amount of marbles that can be shared equally among the students = Condition each student gets one marble = 1 × 3 = 3 marbles
The least amount of marbles that can be shared equally among the students = 3 marbles
2) The number of people born int eh world every minute = 150 people
The number of minute in one hour = 60 minutes
∴ The number of people born every hour = 150 × 60 = 9000 people
Given that the number of hours in one day = 24 hours
∴ The number of people born every day = 9000 × 24= 216,000 people
Given that the number of days in one year = 365 days
∴ The number of people born every year = 216,000 × 365= 78,840,000 people
A local hamburger shop sold a combined total of 676 hamburgers and cheeseburgers on Thursday. There were 74 fewer cheeseburgers sold than hamburgers.
How many hamburgers were sold on Thursday?
Answer:
Step-by-step explanation:
no of hamburgers sold = 375
The number of hamburgers sold on Thursday was 375 hamburgers.
How to calculate the number of hamburgers sold?Let us use 'A' to represent the number of hamburgers sold on Thursday and 'C' to represent the number of cheeseburgers sold.
Based on the provided information: Total number of hamburgers and cheeseburgers sold is 676: A + C = 676.
And the number of cheeseburgers sold = 74 less than the number of hamburgers, which is C = A - 74.
We shall solve this system of equations to find A.
Putting the value of C from the second equation into the first equation:
A + (A - 74) = 676.
Simplify:
2A - 74 = 676.
Add 74 to both sides:
2A = 750.
Divide both sides by 2:
A = 375.
Hence, 375 hamburgers were sold on Thursday.

2. Find the sum of the first 8 terms of a geometric series in which a1 = 3 and r= 2.
=============================================
Work Shown:
a = 3 is the first term
r = 2 is the common ratio
Sn = a*(1-r^n)/(1-r) ... sum of the first n terms
S8 = 3*(1-2^8)/(1-2) ... sum of the first 8 terms
S8 = 3*(-255)/(-1)
S8 = 765
----------
We can generate the first 8 terms to get 3, 6, 12, 24, 48, 96, 192, 384. Each new term is found by multiplying the previous one by 2.
Then add them up to get 3+6+12+24+48+96+192+384 = 765. We get the same result.
Answer: Answer: 765

5. You are constructing a railing to place on a ramp for your handicapped grandmother. You have been given a 12-ft rail and 5 posts to support the railing. The posts are equally spaced under the rail and the first and last posts are positioned at each end of the rail. The ramp rises at an angle of 12°. a. What part(s) will represent the transversal(s)? b. In order to make the posts parallel, what angles must they form with the transversal? c. What angle would they form with the ramp? d. Which angles would be alternate interior, alternate exterior, corresponding, and consecutive interior? Explain your reasoning. e. What do you know about each of these angles? f. How far apart will the posts be?
Answer:
a. The railing is transversal to the posts
b. In order to make the posts parallel, the angle between the posts and the transversal should be = 78°
c. The angle between the post and the ramp is 102° as we reach the post from the bottom and 102° and 78° immediately after the post
d. 1) Alternate interior angles = 78° and 102°
2) Alternate exterior angles = 102°
3) Corresponding angles = 78° and 102° depending on the side of from which we approach the post
4) Consecutive interior = 78° and 102° depending on the side of from which we approach the post
e. The interior angles are supplementary
f. Horizontal spacing between posts = 2.93 ft.
Spacing between posts along the length of the railing = 3 ft. spacing
Step-by-step explanation:
a. A transversal is a line crossing two or more parallel lines which are in a plane at different points
Therefore, the railing is transversal to the posts
b. Whereby the ramp rises at an angle of 12°, the railing, which is the transversal is therefore inclined at 12° to the horizontal and the posts which will be vertical erect will be at 90° to the horizontal
Therefore, in order to make the posts parallel, the angle between the posts and the transversal should be 90° - 12° = 78° for each post to railing.
c. The angle between the post and the ramp before the post as we ascend the ramp is therefore, 180 - 78 = 102° and 78° after the post
d. The alternate interior angles lie on the opposite sides of the transversal = 78° on one side and 102° on the other (Sum of angles on a straight line) which are the angles on the transversal
The alternate exterior angles lie on the exterior opposite sides of the transversal = 102°
Corresponding angles are the angles located in the corresponding positions on the transversal = 78° on one side and 102°as we cross the post (Sum of angles on a straight line)
Consecutive interior angles are the angles that are located on the same part of the transversal = 78° and 102° (Sum of consecutive interior angles of parallelogram = 180°
e. For the posts to be parallel, the consecutive interior angles should be supplementary or equal to 180°
f. Whereby we have a 12-ft rail inclined at 12°, we have;
Horizontal distance covered by the rail = 12 × cos(12) = 11.74 ft
Since we have 5 posts, there 4 equal spaces between them which gives
Spaces between posts = 11.74/4 = 2.93 ft. horizontally and 3 ft. spacing between each post along the railing.
Write an algebraic equation to match each graph. (These graphs are not drawn to scale!)
Answer:
y = |x - 1|
Step-by-step explanation:
This graph is the standard graph of y = |x|, shifted 1 unit right. To shift 1 unit right, we have to replace x by x - 1. This works because it replaces f(1) with f(0), f(2) with f(1), etc., shifting the entire graph right.
FIRST GETS BRAINLLEST If the triangle below is enlarged by a scale factor of 2, what will be the perimeter of the new triangle? 16 units 19 units 21 units 24 units
There are two ways to do this. The first method you would multiply each original side by 2 to get 7 for each side. The new perimeter would be 7+7+7 = 21.
Or you could find the perimeter of the original figure (3.5+3.5+3.5 = 10.5) and then multiply that by 2 to get the same result (10.5*2 = 21)
