Answers

Answer 1

Answer:

1. The angles of a triangle added up all together is 180. So, we can solve a as an equation!

36+57+a=180.

From this, we can figure out a:

a=87

2. The same goes for this one, just a bit different. We write our equation like this:

3x+90=180

we solve this:

3x=90

we divide both sides by 3 and get:

x=30

What is the total surface area of the square pyramid?
48 square meters
64 square meters
76 square meters
88 square meters

Answers

Answer:

Step-by-step explanation:

Isabell, can you see that the sides are 2x6 each?   each half of the triangle will make a total rectangle of 2x6 or 12 square meters

there are 4 of those so 48 sq meters plus the base of 4x4 or 16 sq meters

48+16 = 64 square meters total

Answer:

64 meters squared

Step-by-step explanation:

To find the surface area, we need to find the area of all the faces of the shape. We find the area of a triangle with the formula 1/2 x base x height. Since we have a base of 4 and a height of 6 we multiply the numbers together and get 24 then divide by 1/2 which gives us 12. Since there are 4 total triangles, we are going to multiply 12 x 4 which gives us 48. The last face of the triangular prism is the bottom which is a square. The area of a square can be found by multiplying length x width which is 4 x 4 = 16. For the final step we add 48 + 16 = 64.

Sally lends half her collection of formal attire to her sister Annie, sally then buys four more attires. If she had 12 attires now, how many attires did sally have initially

Answers

Answer:

16 attires

Step-by-step explanation:

Let us represent the number of attires:

Sally has initially = x

Sally lends half her collection of formal attire to her sister Annie

This means, Sally has currently = 1/2x attires

Sally then buys four more attires. If she had 12 attires now.

Hence, this is expressed Mathematically as:

1/2x + 4 = 12

1/2x = 12 - 4

1/2x = 8

x/2 = 8

Cross Multiply

x = 8 × 2

x = 16

Therefore, the amount of attires Sally had initially = 16 attires

The surface area of a sphere is 200.96 square centimeters. What is the approximate volume of the sphere? Use 3.14 for π. Round your answer to the nearest hundredth. A. 696.99 cm3 B. 133.97 cm3 C. 267.95 cm3 D. 334.94 cm3

Answers

Answer:

267.95cm^3

Step-by-step explanation:

S= 4πr^2

Surface area is 200.96

π= 3.142

200.96= 4×3.142×r^2

200.96= 12.57r^2

r^2= 200.96/12.57

= 15.99

= √15.99

r = 3.9

Volume= 4/3πr^3

= 4/3× 3.142×3.9^3

= 267.95 cm^3

What they are asking is in which box do each of the following numbers go into.

[tex]\sqrt{2}[/tex] and [tex]\frac{\pi }{2}[/tex] would go in the 'Between 1 and 2' box.

[tex]\sqrt{5}[/tex] goes under the 'Between 2and 3' box.

([tex]\sqrt{3.5}[/tex])^2 is the exact same as 3.5, as the square root and square cancel each other out, so it goes in the 'Between 3 and 4' box.

Judy and 2 friends won $145.00 at a fundraising raffle! They agreed to share the winnings equally. They received one $100 bill, four $10 bills, and five $1 bills

Answers

Answer:

There are 3 friends (Judy + 2 friends) who won $145.00

They want to share the winnings equally, but they got:

one $100 bill

four $10 bills

five $1 bills.

Assuming that they can share only those bills, the only way to share the winnings equally is:

Each friend gets one $10 bill

Each friend gets one $1 bill

Then each one gets $11.

And there is a surplus of:

one $100 bill (that can't be divided)

one $10 bill (that can't be divided)

two $1 bill (that can't be divided)

Then:

There is a common pool of $100 + $10 + 2*$1  = $112

And each one of the 3 friends gets $10 + $1 = $11

In the case where they can change the bills, each friend will get:

$145/3 = $48.33
