Answer:Carys earns $10 per hour and earn $1 in hour .
Step-by-step explanation:
Given: Carys calculates the total amount E, in dollars, that she earns for working h hours.
She use the equation to calculate the total amount .
Foe h=1,
hence, she earns $10 in one hour.
Therefore, Carys earns $10 per hour.
Let she earn $1 then put E=1 in the equation, we get
Hence, she earn $1 in hour .
No, the three given side lengths could not make a triangle.
8.4 cm is greater than 4.1 cm and 1.3 cm combined, so no matter what angle is between the two shorter sides, it is impossible to fit the 8.4 cm side.
Answer:
Step-by-step explanation:
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
She placed 56 feet of fencing around her garden. This means that the perimeter of the garden is 56 feet. If the length of the rectangular garden is 20 feet, i means that
2(20 + W) = 56
Dividing through by 2, it becomes
20 + W = 28
W = 28 - 20
W = 8 feet
The formula for determining the area of a rectangle is expressed as
Area = length × width
Therefore,
Area = 8 × 20 = 160 square feet
