Consider the following equation.
y = - 15
Which of the following lines is perpendicular to the one above?
OA
y = - - 20
ОВ.
y =
21 – 15
OC.
y = - + 19
OD
y = 1 + 14
Answer:
A
Step-by-step explanation:
To find the perpendicular line you need to find the negative reciprocal of 4/7x which is -7/4x, so A is the correct answer

Here is a story: Lin bought 4 bags of apples. Each bag had the same number of apples. After eating 1 apple from each bag, she had 28 apples left.
Which diagram best represents the story? Explain why the diagram represents it.
What part of the story does
x
represent?
Describe how you would find the unknown amount in the story
Answer:
Let's define the variable x as the number of apples in each bag.
We know that she bought 4 bags, then the total number of apples that she has is:
Apples = 4*x
Now she eats one apple for each bag, then she eats 4 apples, so she now has:
Apples = 4*x - 4
And we know that this is equal to 28, then:
4*x - 4 = 28
now we can solve this for x.
4*x = 28 + 4 = 32
x = 32/4 = 8
x = 8
There are 8 apples in each bag.
For the diagram part, by a small online search y found the image that you can see below.
The diagram that correctly represents this situation is diagram C, where x represents the number of apples in each bag.
In the figure find the value of x figure is not drawn on scale
Answer:
x + 110 + 47 = 180
x = 180 - 157
x = 23

Tom is burning CDs of music he loves. He can burn a CD in 4/5 of an hour. If he has 8 spare hours this week, find 8÷4/5, the number of CDs he can burn in his spare time.
Answer: 10 CD's
Step-by-step explanation:
Given
Tom can burn a CD in [tex]\frac{4}{5}\ \text{of an hour}[/tex]
If he has 8 spare hours in the week, he can burn
[tex]\Rightarrow 8\div \frac{4}{5}=\dfrac{8}{\frac{4}{5}}\\\Rightarrow \dfrac{8\times 5}{4}=2\times 5=10\ \text{CD}[/tex]
Students in a health class are tracking how much water they consume each day. Victoria has two reusable water bottles: a small one and a large one. Yesterday, she drank 3 small bottles and 4 large bottles, for a total of 3,312 grams. The day before, she drank 2 small bottles and 4 large bottles, for a total of 2,888 grams. How much does each bottle hold?
please help
Given :
Let, capacity of small bottle is x and large bottle is y.
To Find :
How much does each bottle hold ?
Solution :
For condition 1 :
3x + 4y = 3312 ...1)
For condition 2 :
2x + 4y = 2888 ...2)
Subtracting equation 2) from equation 1), we get :
x = 424
Putting value of x in equation 1) is :
[tex]y = \dfrac{2888 - (2\times 424)}{4}\\\\y = 510[/tex]
Therefore, capacity of small bottle is 424 gram and large bottle is 510 gram.

What is the value of r?
r= 4 ft
r= 8 ft
r = 16 ft
r = 32 ft
R=8ft
Step-by-step explanation:
Calculate r using the given formula
r = , with Area = 64π
r = ← cancel π on numerator/ denominator
r = = 8
The required value of radius of circle r is 8 ft
From Figure the area of circle is = 64π, we have to find the radius of the circle.
What is area of circle?Area of the circle is = π[tex]r^2[/tex]
since
the area of the circle is given = 64π
And,
Radius = √area/π
radius= √64π/π
Radius = √64
Radius = 8 ft
Thus The required value of radius of circle r is 8 ft.

Answer:
sum of exterior angles of a polygon = 360°
therefore,
x + 5 + x + 10 + 3x - 8 + 5x + 10 = 360°
10x + 17 = 360°
x + 17 = 360 ÷ 10 = 36
x = 36 - 17 = 19
x = 19
rounding off 19 to nearest hundred = 20

A father a son are standing beside each other in the sun. The father is 2 meters tall and casts a shadow 4 meters long. The son is 1 meter long. How long is his shadow
Answer:
to find the sons shadow you would simply multiply the length of his body by 2, therefore his shadow would be 2 meters long
The height of shadow is 2 meter long.
We have,
The father is 2 meters tall and casts a shadow 4 meters long.
let the length of shadow be x.
Using proportion
2/4 = 1/ x
2x = 4
x =4 /2
x = 2 meter
Thus, the height is 2 meter tall.

A circular trampoline has a radius of 8 feet. Wendy wants to buy a cover for the trampoline. What will be the area of the cover
Answer:
Option (3)
Step-by-step explanation:
Area of a circle is given by the formula,
Area = πr²
Here, r = radius of the circle
Since, radius of the circular trampoline = 8 feet
Area of the cover required for the circular trampoline = π(8)²
= 64π square feet
Therefore, Option (3) will be the answer.
