Answer:

$12 per hour

Step-by-step explanation:

To solve how much did Robin earned per hour you just have to do a simple equation, we know that he worked 9 weeks, and that each week he worked 40 hours, so you equation would look like this:

Income=(wageperhour)*(hours worked)

The hours worked is just a math done by multiplying the weeks worked by the hours worked per week that would be:

Hours worked=Hours worked per week*weeks\\Hours worked=(40 hours)*(9 weeks)\\Hours worked=360 hours

So now we just put the data into our equation

Income=(wageperhour)*(hours worked)\\$4320=(wageperhour)*(360)\\wage per hour=4320/360\\ Wage per hour= 12

Step-by-step explanation:

believe it or not, the area of any triangle is

baseline × height / 2

we have here 2 triangles, both with the same baseline (8 cm), but with 2 different heights : 6.5 cm and 4.6 cm.

so, their areas are

8 × 6.5 / 2 = 4 × 6.5 = 26 cm²

8 × 4.6 / 2 = 4 × 4.6 = 18.4 cm²

so, in total, the shaded region is

26 + 18.4 = 44.4 cm²

If angle 1 and angle 2 are vertical. If the measure angle 1= 6x+11 and the measure angle 2= 10x-9, find the measure angle 1
Paraphin [41]

Hey there!!

We know:- <em>Vertically opposite angles are equal. </em>

Hence,

Angle 1 = Angle 2

... 6x + 11 = 10x - 9

... 20 + 6x = 10x

... 20 = 4x

... x = 20 / 4

... x = 5

Angle 1 = 6x + 11

... 6 ( 5 ) + 11

... 30 + 11

... 41

<em>Hence, the measure of angle 1 is 41 degrees. </em>

Hope my answer helps!

Mr. Frank has 1.08 kilograms of fertilizer for the plants in his nursery. He wants every plant to get 93 mg of fertilizer 4 time
joja [24]

Answer: See explanation

Step-by-step explanation:

First and foremost, we should know that: 1 kilogram = 1,000,000 milligrams

Therefore, 1.08kg will be converted to milligram and this will be:

= 1.08 × 1,000,000 milligrams

= 1,080,000 milligrams

Since every plant gets 93mg of fertilizer, the number of plants that can be fertilized will be:

= 1,080,000 / 93

= 11612.903

Therefore, 11612 plants can be fertilized.

The fertilizer left over will be:

= 1,080,000 - (11612 × 93)

= 1080000mg - 1079916mg

= 84 mg
