Answer:
5
Step-by-step explanation:
The diagram shows that 4y = 20.
Then y is one of 4 equal parts, so y = (1/4)(20) = 5.
The value of y is 5.
Luis is making cookies. He needs 1 1/4 cup of sugar to make 12 cinnamon cookies and 1/2 cups of sugar to make 24 chocolate chip cookies. How many cups of sugar does he need to make both recipes?
Answer: 1 3/4 cups of sugar
Step-by-step explanation:
To make the first recipe, Luis needs 1 1/4 cup of sugar.
To make the second recipe, he needs 1/2 cup of sugar.
The number of cups of sugar that he need to make both recipes will be gotten by adding both cups of sugar together. This will be:
= 1 1/4 + 1/2
= 1 1/4 + 2/4
= 1 3/4
Therefore, 1 3/4 cups of sugar are needed

Answer:
There are 3600 seconds in an hour.
non-statistical

Answer:
The third one
Step-by-step explanation:
It can't be the first one since the peak is 4 since it is the highest
It can't be the second one because the data is all different
It could be the third one since their are gaps
And It can't be the fourth one because the range is 7
So it must be the third one

two passenger train traveling in opposite directions meet and pass each other. Each train is 1/18 miles long and is traveling at 40 miles per hr. How many seconds after the front parts of the trains will meet their rear parts pass each other.
9514 1404 393
Answer:
5 seconds
Step-by-step explanation:
Suppose the front parts of the trains meet at point A. Since both are the same length and traveling the same speed, each will pass point A in time ...
time = distance/speed
time = (1/18 mi)/(40 mi/h) = (1/720 h) × (3600 s)/(1 h) = 5 s
That is, the rear part of each train will be at point A 5 seconds after the front part.
The rear parts will pass each other 5 seconds after the front parts meet.

-x + 3y = -12 in slope intercept form. please show step by step. thanks :)
Answer:
y=x/3 - 4
Step-by-step explanation:
add x to get x to the other side
3y= x-12
divide by 3 on both sides to get y by itself y= x/3 - 4 is simplest form
Answer:
slope intercept form is y=mx+b
add x to both sides : 3y=x-12
divide by 3 on both sides : y=(1/3)x-4

What is the slope of (10,3) and (2,3)
Answer:
m=0
Step-by-step explanation:
the formula given for slope (m) calculated from two points is given as (y2-y1)/(x2-x1)
we are given the points (10,3) and (2,3)
label the values of the points to use for the formula:
x1=10
y1=3
x2=2
y2=3
plug into the formula
m=(3-3)/(2-10)
subtract
m=0/-8
divide
m=0
therefore, the slope is 0
Hope this helps! :D
0/-8

tell whether a triangle can have the given angle measures:
47°, 109°, 23°
Answer:
No
Step-by-step explanation:
47 + 109 + 23 = 179
But the angle sum of a triangle is 180.
The product of 0.008 and 10,000,000 is 80,000 because the decimal point in 0.008 moves (how many?) places to the right. A 5. B 6. C 7. D 8.

A new watch costs $38.85, and a new bracelet costs $22.38. If Maddy buys both, how much does she spend? no photo links cus its a write prob
Answer:
$61.23
Step-by-step explanation:
Find how much she will spend by adding the costs together
38.85 + 22.38
= 61.23
So, if she buys both, she will spend $61.23
Answer:
[tex] \bf \huge 61.25[/tex]
Step-by-step explanation:
Given that :A new watch costs $38.85a new bracelet costs $22.38to find :If Maddy buys both, how much does she spend ?explanation :we have,
watch cost = $ 38•85bracelet cost = $ 22•38finding the cost of how much maddy spend for watch and bracelet
⟼ watch cost = $ 38•85
⟼ bracelet cost = $ 22•38
⟼ for finding the both cost add watch and bracelet cost
⟼ $ 38•85 + 22•38
⟼ $ 61•23
∴ maddy cost $ 61•23 for buys both.
The line plot below shows the lengths of bolts Mr. Slivka found in his drawer.
He needs 16 bolts that are longer than 1 inch for a project he is working on.
Does he have enough bolts for his project?
A line plot named
A.
Yes. There are 16 bolts that have lengths greater than 1 inch, which is just enough.
B.
Yes. There are 18 bolts that have lengths greater than 1 inch, which is more than enough.
C.
No. There are only 3 bolts with lengths greater than 1 inch, which is not enough.
D.
No. There are only 12 bolts that have lengths greater than 1 inch, which is not enough.
Answer:
D.)
No. There are only 12 bolts that have lengths greater than 1 inch, which is not enough.
Step-by-step explanation:
Based on information provided by the dot plot above, we can deduce that the number of bta longer Than 1 inch are those with length ; 1 1/8, 1 3/8, 1 4/8
Counting the number of these bolts :
1 1/8 = 5 bolts
1 3/8 = 3 bolts
1 4/8 = 4 bolts
Hence, total number of bolts longer Than 1 inch :
(5 + 3 + 4). = 12 bolts
The number of bolts longer than 1 inch is 16. Therefore, he does not have enough bolt for the project.

Use a Pythagorean Triple to find x.
Answer:
x = 51
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
x² = 45² + 24² = 2025 + 576 = 2601 ( take the square root of both sides )
x = [tex]\sqrt{2601}[/tex] = 51
Answer:
x = 51.
Step-by-step explanation:
The triple you require is 17-15-8
We have x-45-24
- that is three times each number in the triple.
So x = 3*17 = 51.

What is the median? 0.8 1.0 2.7 2.8 3.1 13.3
Answer:
2.75
Step-by-step explanation:
The median is just the middle number in the number set. So, you put the numbers in order (which they already are), and find the middle number. If there are two numbers in the middle (which only happens if there is an even amount of numbers), then you add both of them and divide by 2 (which we must do in this problem).
0.8, 1.0, 2.7, 2.8, 3.1, 13.3
(2.7 + 2.8)/2
(5.5)/2 = 2.75
So, the median is 2.75.
Hopefully this helped, good luck!
Step-by-step explanation:
Arranging the numbers in an ascending order:
0.8 1.0 2.7 2.8 3.1 13.3
Median = (3rd value + 4th value) / 2
[tex] = \frac{2.7 + 2.8}{2} \\ = \frac{5.5}{2} \\ = 2.75[/tex]

The roots of the equation x² + 2x + 4 = 0 are
A) rational and equal
B) rational and unequal
C) imaginary and unequal
D) real, rational, and unequal
Answer:
Option C
Step-by-step explanation:
Given :-
A equation x² + 2x + 4 = 0 .And we need to find out the nature of the roots . The nature of the roots is determined by the Discriminant of the equation , and the Discriminant of a quadratic equation is ,
[tex]:\implies[/tex] Discriminant = b² - 4ac
[tex]:\implies[/tex] Discriminant = 2² - 4(1)(4)
[tex]:\implies[/tex] Discriminant = 4 -16
[tex]:\implies[/tex] Discriminant = (-12)
Now here the value of D is less than 0 .So the roots will be imaginary .
Hence the roots are imaginary and unequal.
