Mathematics

mojhsa [17]3 years ago
5 0

Step-by-step explanation:

Area of one side of the shed

5*4=20

she painted 4 sides so 20*4 =80

Triangle that is part of the pyramid as the roof of the shed has a side of 5. Using the Pythagorean theorem,

{5}^{2}  -  {2.5}^{2}  =18.75

we need to find the square root of 18.75 to find the height of the triangle which is

\sqrt{18.75}  = 4.330127019

that is the height

(base x height) /2 is the formula for a right triangle. there are 2 of these right triangles per side of the roof. so we need to multiply the numbers by 8

\frac{2.5 \times 4.330127019}{2}  \times 8

this number gives us 43.30127019

we can finally add that number to 80 to get the total surface area Zoe painted which is 123.3012702

Slav-nsk [51]
Write the system of equation based on the problem
"A total of 345 tickets that consists of adult tickets and students ticket were sold" could be written as:
∴ a + s = 345 <em>(first equation)</em>
"<span>the number of student tickets sold was two times the number of adult tickets sold" could be written as:
</span>∴ s = 2a  <em>(second equation)</em>
<span>
Solve the system of equation
Substitute 2a as s in the first equation
a + s = 345
a + (2a) = 345
3a = 345
  a = 345/3
  a = 115

There are 115 adult tickets sold.</span>

Jacob is 5 and 5 sixths feet tall. and Linda is 5 and 1 fourth . How much taller is Jacob?
devlian [24]
Jacob=5 5/6 ft
Linda=5 1/4

So to find out the difference, we first have to make the fractions equivalent.

5/6x2/3=10/12
1/4x3/3=3/12

Now we subtract.

5 10/12-5 3/12
=7/12

Jacob is 7/12 ft taller than Linda.

asambeis [7]

Answer:

The temperature is 50^{\circ}F

Step-by-step explanation:

Given

F= (C*1.8) + 32

Required

Find F when C = 10

F= (C*1.8) + 32

Substitute 10 for C

F = 10 * 1.8 + 32

F = 18 + 32

F = 50
