Ahamd wants to cover a box that is 6 cm long 4 cm high and 4 cm wide with material on all the sides how much material does he need
Answer:
128cm²
Step-by-step explanation:
To find out how much material he needs, you need to find the surface area of the box. Each box has 6 sides, 2 of 3 different sides.
Surface area = 2(6 × 4) + 2(6 × 4) + 2(4 × 4)
= 128cm²
2. The numbers from 101 to 150 are written as, 101102103104105.146147148149150.
What will be the remainder when this total number is divided by 3?
Answer:
We know that a number is divisible by 3 if the sum of its digits is a multiple of 3.
if the sum is a multiple of 3 + 1 (like 3*n + 1) the remainder is 1
if the sum is a multiple of 3 + 2 (like 3*n + 2) the remainder is 2.
Then we need to find the sum of all the single digits in the number:
101102103104...149150
the sum of all the single digits is:
( 1 + 1) + (1 + 2) + (1 + 3) + ... + (1 + 4 + 9) + ( 1 + 5)
The method i used is:
(from 101 to 110)
first we sum the hundreds digit 10 times, and then we add the unit digits for each case, this is:
1*10 + (1 + 2+ 3 + 4+ 5+ 6+ 7+ 8 + 9 + 1) = 10 + 46
From (111 to 119)
first we add the sum of the hundreds and tens digits 10 times, and then the units:
2*9 + ( 1 + 2+ 3 + 4+ 5+ 6+ 7+ 8 + 9 )
now if we also add the number 120 (so we have the range 111 to 120)
the sum becomes:
2*9 + ( 1 + 2+ 3 + 4+ 5+ 6+ 7+ 8 + 9 ) + 1 + 2
2*10 + (1 + 2+ 3 + 4+ 5+ 6+ 7+ 8 + 9 + 1 ) = 20 + 46
You already can see the pattern here.
in the range from (121 to 130) we will have the sum equal to 30 + 46
in the range from (131 to 140) we will have the sum equal to 40 + 46
in the range from (141 to 150) we will have the sum equal to 50 + 46
Then the total sum is:
(10 + 20 + 30 + 40 + 50) + 5*46 = 380
We know that 380 is multiple of 3 (because 3 + 8+ 0 = 12)
Then the remainder is 0.

Welcome for the answer. This answer is for good intentions only, report if necessary. Thank you and have a good rest of your day!what is 129.392 rounded to nearest hundredth?
Answer:
130
Step-by-step explanation:
The numbers after the decimal point are not up to 1, so they cannot be added up to the integer.
Answer:
130 to the nearest 100th
Step-by-step explanation:
100 - 129.392 = 29.392
30 - 29.392 = 0.608
1 - 0.608
= 0.392
0.392 - 0.002
= our negative thousandth
our negative 100th is 0.39 in 129.39
What is closer to 100 is for the other side 120 or 130 in 129.38
The answer is 130

Henri has $24,000 invested in stocks and bonds. The amount in stocks is $6,000 more than three times the amount in bonds
Answer:
s + b = $24,000
And,
s = 3b + $6,000
Step-by-step explanation:
Let us assume the stock be s
And, the bonds be b
So according to the question
It is given that
s + b = $24,000
And,
s = 3b + $6,000
The answers are
s + b = $24,000
And,
s = 3b + $6,000

8) Do these ratios form a proportion?
20 pedestrians : 5 years
7 pedestrians : 1 year
Please provide explanation.
Answer:
Since the division of the number of pedestrians by the number of years yields different values for each ratio, these ratios do not form a proportion.
Step-by-step explanation:
They will form a proportion if the division of the number of pedestrians by the number of years yields the same results.
20 pedestrians : 5 years
20/5 = 4 pedestrians per year.
7 pedestrians : 1 year
7/1 = 7 pedestrians per year.
Since the division of the number of pedestrians by the number of years yields different values for each ratio, these ratios do not form a proportion.

Which characteristics describe the graph of (x – 6)2 + (y – 12)2 ≤ 196?
circle with solid boundary, center at (6, 12), bounded solution set
circle with solid boundary, center at (–6, –12), bounded solution set
circle with solid boundary, center at (6, 12), unbounded solution set
circle with solid boundary, center at (–6, –12), unbounded solution set
The characteristics describe in the graph of the circle inequality are a circle with a solid boundary, center at (6, 12), and bounded solution set option first is correct.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have a circle equation in the inequality form:
(x – 6)² + (y – 12)² ≤ 196
The center of the circle is at (6, 12)
The radius of the circle is:
r² = 196
r = 14 units
After drawing a circle on the coordinate plane.
We will see, a circle with a solid boundary, center at (6, 12), and bounded solution set.
Thus, the characteristics describe in the graph of the circle inequality are a circle with a solid boundary, center at (6, 12), and bounded solution set option first is correct.

Answer:
g(-1) = 4
Step-by-step explanation:
Given:
g(x) = [tex] \frac{3x^2 - 2x + 7}{2x + 5} [/tex]
To find g(-1), substitute x = -1
Thus:
g(-1) = [tex] \frac{3(-1)^2 - 2(-1) + 7}{2(-1) + 5} [/tex]
g(-1) = [tex] \frac{3 + 2 + 7}{-2 + 5} [/tex]
= [tex] \frac{3 + 2 + 7}{-2 + 5} [/tex]
= [tex] \frac{12}{3} [/tex]
g(-1) = 4
If a kickball has the diameter of 12 inches , how much air could this call contain ?
Answer:
904.32. cu.in
Step-by-step explanation:
diameter= 12 inches
radius= 13/2=6 inches
volume of sphere= 4/3 πr³ = 4/3 ×π × 6³ = 904.32 cu.in
The amount of air contain in kickball is,
⇒ V = 904.32 in³
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
A kickball has the diameter of 12 inches.
Hence, We get;
⇒ Radius = 12/2
⇒ Radius = 6 inches
Since, We know that;
⇒ volume of sphere= 4/3 πr³
Hence, We get;
⇒ V = 4/3 ×π × 6³
⇒ V = 904.32 in³
Thus, The amount of air contain in kickball is,
⇒ V = 904.32 in³

What are the six trigonometric ratios?Trigonometric ratios for a right angled triangle are from the perspective of a particular non-right angle.
In a right angled triangle, two such angles are there which are not right angled(not of 90 degrees).
The slant side is called hypotenuse.
From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called base.
From that angle (suppose its measure is θ),
[tex]\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}\\\cos(\theta) = \dfrac{\text{Length of Base }}{\text{Length of Hypotenuse}}\\\\\tan(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of base}}\\\\\cot(\theta) = \dfrac{\text{Length of base}}{\text{Length of perpendicular}}\\\\\sec(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of base}}\\\\\csc(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of perpendicular}}\\[/tex]
For this case, we have to express x in terms of y for [tex]\cos(x^\circ) = \sin(y^\circ)[/tex]
Since 0 < x < 90, and 0 < x < 90 so taking inverse cosine gives:
[tex]x^\circ= \cos^{-1}(\sin(y^\circ))[/tex]
Thus, the expression of x in terms of y for the case when cos(xº) = sin(yº) is [tex]x^\circ= \cos^{-1}(\sin(y^\circ))[/tex]

A carpenter is creating two new templates for his designs. One template will be in the shape of a right triangle, where the longer leg is 4 inches more than six times the shorter leg. The second template will be in the shape of a rectangle, where the width is 5 inches more than the triangle’s shorter leg, and the length is 3 inches. The carpenter needs the areas of the two templates to be the same. Write a system of equations to represent this situation, where y is the area, and x is the length of the shorter leg of the triangle. Which statement describes the number and viability of the system’s solutions?
A. The system has two solutions, but only one is viable because the other results in negative side lengths.
B. The system has only one solution, and it is viable because it results in positive side lengths.
C. The system has only one solution, but it is not viable because it results in negative side lengths

60
24
600
6
Answer:
B, 24
Step-by-step explanation:
2 : 5 ratio of catching catfish
X : 60
2/5 = X/60
6 x (2/5) = (X/60) x 60
60 x (2/5) = X
X = 60 x (2/5)
X = 24
