To answer the question above, we let s be the cost of a shirt and h be the cost of each hat such that the equations that would best represent the given are:
10s + 20h = 490
20s + 30h = 860
The system of equations is the answer to the first question and the values of s and h are $25 and $12, respectively.

Find the missing length of the triangle.

Dafna1 [17]

There are special properties to certain right triangles.

A 3-4-5 triangle will always be a right triangle. 9 divides into 3, and 15 divides into 5, so you can use ratios to find b.

Since 9 divides into 3, we will use this to set up proportions for the missing value:

$\frac{9}{3} = \frac{b}{4}$

Cross multiply the fractions.

$3b = 36$

Divide both sides by 3.

$b = 12$

The missing value is 12.

Last month, gianni used 6GB out of 8GB included in his cell phone plan. Lamar used 4GB out of 5GB included in his cell phone pla

anygoal [31]

Answer:

Lamar used a greater percent in their data (75%)

Step-by-step explanation:

If Gianni used 6 out of 8 and Lamar 4 out of fie we need to calculate the perecentages:

GIANNI:

If 8GB ---> 100%

6GB ----> X

we do the ecuation and the result is 75%

LAMAR:

If 5GB -----> 100%

4GB ------> X

we do again another ecuation. The result is 80%

solution: Lamar used a greater percent in his data. (80%)

What is the easiest way to put a percentage into a fraction

Artyom0805 [142]

Put the percent over 100 and reduce.

For example, 75%. Put it over 100: 75/100. Reduce to 3/4.
