Answer:

15.8

Step-by-step explanation:

since you're trying to figure out the perimeter of the rectangle you would use the formula 2L + 2W.

3.7 times 2 is 7.4

and 4.2 times 2 is 8.4  

so, add 7.4 and 8.4

<u><em>= 15.8</em></u>

Answer:

15.8m

Step-by-step explanation:

Your perimeter is given by the sum of four sides of the rectangle:

Perimeter = 3.7m*2 + 4.2m*2 = 7.4m + 8.4m = 15.8m

solniwko [45]

Answer:

Bola is 8 years old.

Step-by-step explanation:

Let Bola's age be x

Dada's age be y

Ayo's age be z

If the sum of ages of Bola, Dada and Ayo is 32 years, then;

x + y + z = 32

If they share a sum of money in ratio of their ages, then the ratio of their ages will be x : y : z

Also if Bola gets N400, Dada get-N400 and Ayo get N800, then the total amount of money shared will be expressed as:

T = 400 + 400 + 800

T = N1600

Next is to get the age of Bola

\frac{age \ of \ bola}{32}* Total \ amount \ shared = Bola's \ Share

Substitute the required variables and values into the formula;

\frac{x}{32}*1600= 400\\50x=400\\x=\frac{400}{50}\\x=8

This shows that Bola is 8 years old

vovangra [49]

Answer:

The method that is valid in finding the unit rate for a proportional relationship is by:

Look at the graph of the relationship. Count the number of units up and the number of units to the right one must move to arrive at the next point on the graph. Write these two numbers as a fraction. The unit rate is the slope, which is the rise over run.
