Heather and her friends are painting the walls of a storage room in the basement. Each wall is 9 m long and 2 m high. There are
inna [77]

Answer:

  • 7 L
  • $26.25

Step-by-step explanation:

The four walls have a linear length of (9 m)×4 = 36 m. Of that, the two 1-meter doors are not painted, so the linear length of the painted area is 34 m. The painted area is 2 m high, so the total area being painted is ...

  A = LW

  A = (34 m)(2 m) = 68 m²

The amount of paint needed for this area is ...

  (68 m²) × (1 L/(10 m²) = 6.8 L

If we assume the paint only comes in units of 1 L, then Heather will need 7 L of paint.

The cost of 7 L of paint is ...

  (7 L) × ($3.75/L) = $26.25

Heather will need 7 L of paint, for a total cost of $26.25.

Can I get help with this
Marta_Voda [28]

Answer:

X = 60

Y = 50

Step-by-step explanation:

The total degrees of a triangle is 180 degrees. For the middle triangle, 50+70=120 so 180-120=60.

On the far right, Y=50 because you take 50 degrees from the middle triangle, and insert it there.

Please help! i don't know what to do, my formulas are not working for me. If anyone could please help i would really appreciate
Burka [1]

Answer:

  • The radius is r = 3 in,
  • The height is h = 4 in

<u>The area of the base:</u>

  • A(b) = πr² = π(3²) = 9π in²

<u>The circumference of the base:</u>

  • C = 2πr = 2π(3) = 6π in

<u>The area of the lateral surface:</u>

  • A(l) = Ch = 6π(4) = 24π in²

<u>The surface area:</u>

  • S = 2A(b) + A(l) = 2*9π + 24π = 42π in²

SpyIntel [72]

Hey there! I"m happy to help!

We see that 1 inch is equal to 5.6 miles for this scale factor. If we have three inches, we simply multiply 5.6 by 3 to figure out how many miles this is!

5.6(3)=16.8

Therefore, Janet's home is 16.8 miles from her office.

Have a wonderful day! :D
