Answer:

Slope and a point that is not an intercept

Let

x ----> the time in hours

y ----> the area (in square meters) left to paint

we know that

Hiro paint at a rate of 8 square meters per hour

The rate is equal to the slope of the linear equation

we have the point (3, 28) ---> After 3 hours of painting, he had 28 square meters left to paint.

therefore

we have

Answer:

5.2 feet

Step-by-step explanation:

It helps if you can make a drawing.

You are looking for the adjacent side of the 71° angle in a right triangle and 15 is the opposite side of the angle.

Let x = the distance from the building to the base of the ladder

Tan 71 = 15/x

xtan71 = 15

x = 15/tan 71 = 5.2 feet

Answer: The length of the hypotenuse (c) is 5

Step-by-step explanation:

Use the Pythagorean Theorem

a² + b² = c²

a & b are the legs (b is the base)

c = hypotenuse

a = 4

b = 3

a² + b² = c²

4² + 3² = c²

16 + 9 = c²

25 = c²

√c² = √25

c = 5

Answer: 284.7

Step-by-step explanation:

radius of cone and hemisphere are the same

volume of half sphere=(1/2)*(4/3)*[tex]\pi r^{3}[/tex]

                                    =(1/2)*(4/3)*3.14*[tex]4^{3}[/tex]                       (4*4*4=64)

                                    =133.97333

                                    =133.97

volume of cone= (1/3)[tex]\pi r^{2}[/tex]h

                         =(1/3)*3.14*[tex]4^{2}[/tex]*9                                      (4*4=16)

                         =150.72

total volume=133.97+150.72

                    =284.69

                    =284.7

You can buy 10 magazines in $60.

A unit rate means a rate for one of something.

Given that, the cost of 4 magazines is $24.00

For 4 magazine → $24

So, for 1 magazine = 24/4 = $6

So, in $60,

60/6 = 10

Hence, you buy 10 magazines in $60.

Answer:

5

Step-by-step explanation:

the slope is the change in y divided by the change in x

as y goes up 5 x goes up 1

5/1=5 so the slope is 5

Answer:

6

Step-by-step explanation:

To find the slope you use rise over run.

Count how far each of the dots are from each other and you should get 6. That is your rise. See how far it goes to the right or left and you should get 1, which is your run.

Since it is rise over run, it would be 6/1, which makes your answer 6

Answer:

Each additional cup is 1 centimeter.

Step-by-step explanation:

We know this because we can see the height on the graph. For each number of cups increased (y-axis), 1 centimeter in height increases as well.

Therefore, we can say that each additional cup is 1 centimeter.

Answer: Each pair of gloves costs $15 and each pair of hat costs $10.

Step-by-step explanation:

Let x = Cost per pair of gloves

y= Cost per hat.

As per given, we have

[tex]5x+2y=95 \ \ \ \ (i)\\4x+y=70\ \ \ \ \ (ii)[/tex]

Multiply (ii) by 2 , we get

[tex]8x+2y=140\ \ \ \ (iv)[/tex]

Eliminate (i) from (iv), we get

[tex]3x=45\\x=15[/tex]

Put this in (ii), we get

[tex]4(15)+y=70\\60+y=70\\y=10[/tex]

Hence, each pair of gloves costs $15 and each pair of hat costs $10.
