Claire is painting some doors that are all the same size. She used 2 liters of paint to cobe 1 3/5 doors. How many liters of pai

Deffense [45]

Answer:

$1 \dfrac{1}{4} \ liters$

Step-by-step explanation:

Given that:

Claire uses 2 liters of paint to cover 1 3/5 doors

Then in order for her to paint 1 door, She will need:

2 L = 1 3/5 door

x L = 1 door

$x (L) = \dfrac{2 L \times 1 door }{ 1 \dfrac{3}{5} \ door}$

$x (L) = \dfrac{2 L }{ 1 \dfrac{3}{5} }$

$x (L) = \dfrac{2 L }{ \dfrac{8}{5} }$

$x (L) = \dfrac{2 L\times 5 }{ 8 }$

$x (L) = \dfrac{10 \ L }{ 8 }$

$x(L) =1 \dfrac{1}{4} \ L$

PLZ HELP SCALE FACTOR TRIANGLE<br><br> A. 10.5 cm<br> B. 31.5 cm<br> C. 63 cm<br> D. 189 cm

Anarel [89]

If two similar triangles have sides in the ratio a : b, then their areas are in the ratio a² : b².

We have the ratio:

$54:18=\dfrac{54}{18}=3:1$

Area of the smaler triangle = x

Area of the larger triangle = 567 cm²

Therefore we have the equation:

$567:x=3^2:1^2\\\\\dfrac{567}{x}=\dfrac{9}{1}\qquad|\text{cross multiply}\\\\9x=567\qquad|\text{divide both sides by 9}\\\\x=63$

<h3>Answer: C. 63 cm²</h3>

Pls help The surface area of a cone is given by the formula<br> S= al +712. Solve the formula for 2.

Luda [366]

Answer:

l = (S/pi)-r^2

Step-by-step explanation:

Just rearrange the equation.

S = pi*l + pi * r^2

S-pi*r^2 = pi*l

l = (S-pi*r^2)/pi

l = (S/pi)-r^2
