Sandra can run 3 miles in 20 minutes. How many minutes will it take her to run 7 miles?
Answer:
46.7 minutes to run 7 miles
Step-by-step explanation:
3 miles in 20 minutes boils down to the unit rate 3/20 miles/minute.
Multiply 7 miles by the unit rate (20/3 minutes/mile):
(7)(20)
---------- minutes, or approximately 46.7 minutes to run 7 miles

PLEASE HELP ILL MAKE BRAINLIEST
Answer:
56°
Step-by-step explanation:
180 = 40 + (2x) + (3x)
180 - 40 = 40 + 5x - 40
140/5 = 5x/5
x = 28
2(28)
= 56
Answer:
m∠A = 56°
Step-by-step explanation:
A triangle contains 180°. So
180 - 40 = 140
2x + 3x = 140
5x = 140
x = 28
Now, plug in the value for x.
2(28) = 56
Check your work.
40 + 56 + 84 = 180

Lynette has a metal doorstop with the dimensions shown.
Each cubic centimeter of the metal in the doorstop has a mass
of about 8.3 grams. Find the volume of the metal in the
doorstop. Then find the mass of the doorstop.
Volume = 105in³
Mass = 871.5g
To find the volume of the metal we can find the area of a base, and multiply it by the prism's width.
The base is 30cm in area, and the width is 3.5cm, which makes the volume 105in³
The mass of the doorstop can be found by just multiplying the grams per cubic centimeter by the volume, which would be 871.5g

I make $8 dollars per hour (H) for babysitting. I make a total (T) dollars babysitting on Saturday. In the space below, identify the Independent Variable (either H or T), the Dependent Variable (either H or T), and write an equation based on this information (include 8, H, T, and an = sign).
Answer: 8H=T
Step-by-step explanation:
8 is dependant on the hours so you put it together. Your independent
value is T since it is by itself. So your answer becomes.

A girl throws a paper airplane from her treehouse. The height of the plane is a function of time and can be modeled by the equation ℎ()=25+2.5−122. Height is measured in feet and time is measured in seconds.
h(0) show the initial height of the plane, that is 25 feet.
The given equation is h(t)=25+2.5t-1/2 t².
Here, h(0)=25+2.5(0)-1/2 (0)²
h(0)=25
This shows the initial height is 25 feet.
Therefore, h(0) show the initial height of the plane, that is 25 feet.

A girl throws a paper airplane from her treehouse. The height of the plane is a function of time and can be modeled by the equation h(t)=25+2.5t-1/2 t². Height is measured in feet and time is measured in seconds.
Evaluate h(0) and explain what this value means in this situation.
rose watches a circular ornament that has 6 equally spaced stones. identify x
Answer:
x = 60°
Step-by-step explanation:
It is given that the stones are equally spaced. As the circle is divided into 6 parts by 6 split points and there are 360∘ in the circle, each part equals 360∘/6 = 60∘. So,
mAB◠ = 60∘
mBC◠ = 3 (60∘) = 180∘
If a tangent and a secant intersect in the exterior of a circle, then the measure of the angle formed is half the difference of the measures of its intercepted arcs.
x = 1/2 (mBC◠ − mAB◠)
Substitute the known values into the formula.
x = 1/2 (180∘ − 60∘)
= 1/2 (120∘)
= 60∘
Therefore, x = 60∘.

There are 5 green skittles, 4 orange skittles, and 3 red Skittles in a bag. What is the probability of red Skittle, Not replacing it (eating it), then picking a green skittle?
Answer:
3/12
Step-by-step explanation:
the entire bag has 12 skittles. there are only 3 red. This gives a fraction of red skittles/entire bag in order to get the probability. So this would be 3/12 in this most basic sense? I am not sure if you need to go further than this or not. Hope this helps!
According to the graph, what is the value of the constant in the equation
below?
Height=
Constant/Width
(4, 25)
(5, 20)
(10, 10)
(20,5)
Answer:
100
Step-by-step explanation:
x-value is width and y-value is height. Therefore if you multiply the height x width you get the constant.
The value of the constant in the equation is 100.
What is the graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.
Given that, Height=Constant/Width
1) (4, 25)
Here, Height = 25 and Width = 4
25 = Constant/4
Constant = 100
2) (5, 20)
Here, Height = 20 and Width = 5
20 = Constant/5
Constant = 100
3) (10, 10)
Here, Height = 10 and Width = 10
10 = Constant/10
Constant = 100
4) (20, 5)
Here, Height = 20 and Width = 5
20 = Constant/5
Constant = 100
Therefore, the value of the constant in the equation is 100.

the diagram shows a cuboid.what is the surface area of the cuboid
plz help
Answer:
202 cm
Step-by-step explanation:
You need to add the areas of the faces, and since it is a cuboid opposite faces are the same. If you do 2(5x9) + 2(4x9) + 2(4x5) you will get your answer.
Answer:
Hello Love! Answer: 202
Step-by-step explanation:
First off we have to do all 6 faces remember that each face will have a matching face that goes along with it so Imma start with the front face that would be 9 x 5 = 45 same for back face
Then ill do sides that will be 5 x 4 = 20 for both left and right sides Then ill do top and bottom
thats 4 x 9 = 36 Now ill add all of these up.
So 45 + 45 + 20 + 20 + 36 + 36 and that = 202
