Answers

Answer 1
A) c=18
0.5c^2 +13=94
subtract 13 from both sides
0.5c^2 = 81
Square root of both sides to get c alone
0.5c=9
double c to make it just c
c=18

B) x=8
(x-2)^2+1=37
Subtract one from each side
(x-2)^2=36
square root each side
x-2=6
add the 2 over
x=8

How would you calculate the area of the quarter circle represented in the upper left hand corner of this figure?

(see pictures for answer options)

Answers

Answer:

Step-by-step explanation:

To find the area of a quarter circle, find the area of the whole circle by using the formula A = pi * r^2 and then divide by 4. To find the perimeter of the quarter circle, find the circumference of the whole circle, divide by 4, and then add the radius twice.

Answer: [tex]\frac{\pi *r^{2} }{4}[/tex]

Step-by-step explanation:  We know that the formula for the area of a whole circle is πr². A quarter circle is one-fourth of a circle, so if we divide the area of the whole circle into four, we can find the area of the quarter circle: [tex]\frac{\pi *r^{2} }{4}[/tex]

Clare has a set of cubes with a volume of 1 cm³ each. She also has a box with a volume of 24 cm³. Exactly two layers of cubes can fit in this box. How many cubes must be in each layer? its a school problem I'm having trouble with

Answers

Answer:

12 cubes

Step-by-step explanation:

If the total volume of the box is 24 cm³ and the volume of each cube is 1 cm³ then that means that 24 total cubes can fit perfectly inside the box. Since there can only be two layers of cubes then we simply need to divide the total amount of cubes that will fit in the box by 2 to find the number of cubes in each layer...

24 / 2 = 12 cubes

Finally, we can see that each layer within the box will contain 12 cubes

Step-by-step explanation:

35 + 15 + 5 = 55

60 - 55 = 05

5:05

Answer: 5:05 pm. (C)

Step-by-step explanation:

For this, you have to add up the times. 35+15+5. That is 55 minutes. If it would take 55 minutes, you will want to subtract 55minutes from the time you want it to be done. This will give us 5:05pm.

What type of angle relationship is shown?

Answers

Answer:

straight angle

Step-by-step explanation:

9x_15+2x_3=180

11x_18=180

11x=180+18

11x=198

x=198÷11

x=18

Answer:

The angles are a linear pair.

x = 18

Step-by-step explanation:

The angles are a linear pair, meaning the angles add up to 180 degrees.

(9x - 15) + (2x - 3) = 180

11x - 18 = 180

11x = 198

x = 18

Answer:

$326.94

Step-by-step explanation:

For this equation you are going to do a exponential function, since we are working with percents. To do this you will make the equation

(starting price)x(1-percent)^(t) t=years

which will create the equation

800(0.88)^t

You will then plug in t=7

800(0.88)^7 =

800(0.409) =
