Answer:

4.5 : 1

45 : 10

Step-by-step explanation:

Given ratio:  13.5 : 3

To calculate equivalent ratios, we need to do the same operation to both sides of the ratio.

To reduce 3 L of paint to 1 L of paint, we need to divide by 3.

Therefore, we should also divide 13.5 by 3:

13.5 ÷ 3 : 3 ÷ 3

= 4.5 : 1

To increase 1 L of paint to 10 L of paint, we need to multiply by 10:

4.5 × 10 : 1 × 10

= 45 : 10

Willy can cover in 1L paint

\\ \rm\rightarrowtail \dfrac{13.5}{3}=4.5m^2

  • 1st box should be filled with 4.5

Can cover in 10L

\\ \rm\rightarrowtail 4.5(10)=45m^2

Second one should be filled with 45

Help I need to get this done I have 15 questions
ivanzaharov [21]

Answer:

8 cm

Step-by-step explanation:

(See the image attached for details)

  • The blue segment measures 15 cm
  • The green segment measures 7 cm
  • The green and yellow segment when added form the blue segment
  • So: ? + 7 = 15

Solve:

? + 7 = 15

Subtract 7 on both sides:

? + 7 = 15

   -7     -7

? = 8 cm

Therefore, the yellow segment, or the missing side length, measures 8 cm.
