Melinda worked 6.5 hours at her job. She makes $9.50 per hour. How much money did she earn for the day ?
Lera25 [3.4K]

Answer:

$61.75

Step-by-step explanation:

Hello,

If Melinda earns $9.50 per hour and she worked 6.5 hours, then her earnings for that day was $61.75.

This is simply the product of $9.50 * 6.5 = $61.75.

This assumption of earnings doesn't include tax reductions, unless her hourly pay includes those.

Cheers.

Find the value of y.
Lelechka [254]

Answer:

y = 6

Step-by-step explanation:

This is a special right triangle with angle measures 90° 60° 30°

the side length that sees angle measure 30 is represented with x

the side length that sees angle measure 90 is represented with 2x

and the side length that sees angle measure 60 is represented with x√3

the side length that sees angle measure 90 is given as 4√3 which means 2x = 4√3 divide both sides by 2

x = 2√3 now to find y, we need to multiply this value by √3

2√3 × √3 = 2 × 3

X=18

Explanation:

The sum of the 3 angles in a triangle is 180∘

hence , the sum of the 3 angles given must equal 180

We can form an equation

2x + 3x + 5x = 180 ⇒10x=180⇒x=180/10
x=18


2(x) = 2(18)=36
3(18)=54
5(18)=90

elena-14-01-66 [18.8K]

Answer:

number of math problems = 26

number of science problem = 16

Step-by-step explanation:

a total of 42 math and science problems for homework

Let m be the number of math problems and 's' be the number of science problems

m+s=42

You have 10 more math problems than science problems

m=s+10

substitute s+10 for m in the first equation

m+s=42

s+10+s=42

2s+10=42

subtract 10 from both sides

2s = 32

divide both sides by 2

s= 16

m=s+10

m=16+10

m=26

number of math problems = 26

number of science problem = 16
