Steve puts an 18-foot ladder against his house. The ladder reaches a height of 15 feet on the house. How far is the bottom of the ladder from the base of the house? Leave the answer as a simplified square root.
Answer:
[tex]3 \sqrt{11} [/tex]
Step-by-step explanation:
Since we are given the hypotenuse which is 18 since it slanted, and leans on the house. And we are given one of the legs which is 15 since it is vertical. We can use the pythagorean theorem to solve for this problem.
[tex] {a}^{2} + {b}^{2} = c {}^{2} [/tex]
where a and b are the legs and c is the hypotenuse l.
Let plug it in
[tex] {a}^{2} + 15 {}^{2} = {18}^{2} [/tex]
[tex] {a }^{2} + 225 = 324[/tex]
[tex] {a}^{2} = 99[/tex]
[tex]a = \sqrt{99} [/tex]
[tex]a = \sqrt{9 \times 11} [/tex]
[tex]a = 3 \sqrt{11} [/tex]

what is 5/4 divided by 10 pls be right if u were right ill give u brainliest!!!!!!!!!!!!!!
Answer:
0.004.
Step-by-step explanation:
First, I'll change [tex]\frac{5}{4}[/tex] to a decimal.
[tex]\frac{5}{4} = 1.25.[/tex]
Then, we divide.
[tex]\frac{1.25}{10} = 0.004.[/tex]
The answer is 0.004.

Tammy has a rectangular rug with an area of 21 square feet. The rug is 4 feet longer than it is wide. Which equation can be used to determine the length and the width of the rug?
A.
21 = 4w^2
B.
21 = w^2 + 4w
C.
21 = w^2 – 4w
D.
21 = w^2 + 4
Answer:
D
Step-by-step explanation:
The equation to determine the length and width of the rug is 21 = w² + 4w.
What is Rectangle?A rectangle is a four sided figure with opposite sides are equal .
Area of a rectangle = Length x width
Given that A rectangular rug with an area of 21 square feet.
The rug is 4 feet longer than it is wide.
Let 'l " be the length of the rug and 'w' be the width of the rug
Length is 4 feet longer than its width
l = w + 4
Area is 21 square feet.
Area = l x w
21 = (w + 4)w
21 = w² + 4w
The equation to determine the length and width of the rug is 21 = w² + 4w.
So width is 3 ft
Length = w +4
length = 3+4= 7 feet
Thus Length of the rug is 7 feet
Length of rug = 7 feet
width of the rug = 4 feet

A company is going to make a water tank in the shape of a cylinder. As shown below, the tank will have a height of 2ft and a radius of 5ft. The tank will be made from metal (including its top and bottom). Suppose the total cost of the metal will be 8572.20. How much will the metal cost per square foot? Use 3.14 for pi, and do not round your answer.
Please give an understandable step-by-step explanation. Thank you !!
Answer:
$39 per square foot.
Step-by-step explanation:
The cylinder has a height of 2 feet and a radius of 5 feet.
The total cost of the metal will be (assuming US dollars) $8572.20.
And we want to determine the cost per square foot.
First, we can find the surface area of the cylinder. The surface area for a cylinder is given by the formula:
[tex]SA=2\pi r^2+2\pi rh[/tex]
Where r is the radius and h is the height.
Since the radius is 5 feet and the height is 2 feet and using 3.14 for π, the surface area is:
[tex]SA=2(3.14)(5)^2+2(3.14)(5)(2) =219.8\text{ feet}^2[/tex]
Therefore, to find the cost of metal per square foot, we can divide the total cost over the amount of surface area. Hence:
[tex]8572.20 / 219.8= \$ 39 \text{ per square foot}[/tex]
So, the metal costs $39 per square foot.

Write the equation of the line that goes through the point (6, O) and has a slope of -1/2
Answer:
y = -1/2x + 3
Step-by-step explanation:
y - y₁ = m(x - x₁)
⇒ y - 0 = -1/2(x - 6)
⇒ y = -1/2x + 3
