A kitchen counter will be designed according to the measurements of the diagram in the image. What is the area of the surface of the counter in square feet?
A. 27 ft²
B. 31.5 ft²
C. 36 ft²
D. 40 ft²

Answers

B. 31.5 ft^2 because you find the area of each rectangle and add them and then find the area of the triangle and add it in to get 31.5 ft^2
3 x 5 = 15ft
3 x 4 = 12ft
3 x 3 = 9 divided by 2 = 4.5
15 + 12 + 4.5 = 31.5 ft

Alright so A triangles perimeter is always going to be 90°

So for #1 You would add 18+24= 42 then subtract 42 from 90. 90-42=48. So for the first equation the side would be 48ft.

And for #2 You add 41+40= 81 then subtract 81 from 90 90-81=9 so the answer to the second equation would be 9 ft.

Hope this helps! :)

Answer:

Step-by-step explanation:

a² + b² = c² (pythagorean theorem formula)

let's take 18 as a and 24 as b

So, you'll write it as

18² + 24² = c²

324 +  576 = 900²

c² =810000

c= [tex]\sqrt810000[/tex] = 900

c=900ft

To divide exponents, you just have to subtract the exponents from eachother, x^8/x^3, 8 - 3 = 5, so it is x^5

Answer:

You can keep the base same and subtract the exponents since the function asks us to divide.

Step-by-step explanation:

⇒ [tex]\frac{x^8}{x^3}[/tex] = x⁸ - x³

⇒ 8 - 3= 5

Find the perimeter of the figure.

Answers

Answer:

97 cm

Step-by-step explanation:

10+3+3+33+33+15=97

Answer:

97 cm

Step-by-step explanation:

Hi there!

The perimeter of a figure is the distance around it. To find P, add all the edge measurements:

P = 10+3+33+15+33+3

P = 13+48+36

P = 61+36

P = 97

Therefore, the perimeter of the figure is 97 cm.

If 90 females and 120 males out of 504 total students get to school by car, what is the relative frequency of females who get to school by car in relation to the total students at the school?

Answers

Answer:

0.1786 = 17.86%

Step-by-step explanation:

120 + 90 = 210/504 journey by car

Relative frequency of 90/ 504

= 90/504 =0.178571429

0.1786 = 17.86%

The requried relative frequency of females who get to school by car in relation to the total students at the school is approximately 0.1786 or 17.86%.

What is the relative frequency?

Relative frequency is a measure that indicates the proportion or percentage of times an event occurs in relation to the total number of events. It is calculated by dividing the frequency of an event by the total number of events. The result is a decimal or a percentage.

Here,
The total number of students who get to school by car is 90 + 120 = 210.

The relative frequency of females who get to school by car is the number of females who get to school by car divided by the total number of students at the school, which is 504:

90/504 = 0.1786

Therefore, the relative frequency of females who get to school by car in relation to the total number of students at the school is approximately 0.1786 or 17.86%.

V = π r^2 h
226.2 = (3.14) (3)^2 h
226.2 = (3.14) (9) h

226.2 = 28.26 h divided by 28.26
226.2 divided by 28.26 = h
