Step-by-step explanation:
a^2+b^2=c^2
y^2+8^2=17^2
Step 1: Simplify both sides of the equation.
y^2+64=289
Step 2: Subtract 64 from both sides.
y^2+64−64=289−64
y^2=225
Step 3: Take square root.
y=15

Triangle def is equilateral. If the perimeter of def is 36, the length of de is 5x-8, then what is the value of x
Answers
Answer:
4
Step-by-step explanation:
All the sides of an equilateral triangle are equal, hence the perimeter is expressed as P = 3s
s is one of the side length
Given DE = 5x - 8
P = 3DE
P = 3(5x-8)
36 = 3(5x-8)
36/3 = 5x-8
12 = 5x - 8
5x = 12+9
5x = 20
x = 20/4
x = 4
Hence the value of x is 4

A man wants to enclose a rectangular garden adjacent to a river. The length of the rectangle is two times the width. How many linear feet of the fence must he buy if he does not need fencing along the river and the perimeter of the rectangle is 240 feet?
Answers
Answer:
200, 160
Step-by-step explanation:
if perimeter is 240 it means sides are 40 by 80.
if he does not need to place fencing on one side, they remove one 80 or 40,
40+80+80=160 or 40+40+80=200

Notice that there are similar triangles here:
[tex]\triangle ABD \sim \triangle FED[/tex][tex]\triangle ACD \sim \triangle AEF[/tex]Set up proportions to find the values of x, y, and z.
[tex]\displaystyle \text{Equation I: }\frac{FD}{AD} = \frac{FE}{AB}[/tex][tex]\displaystyle \text{Equation II: } \frac{A F}{AD}=\frac{EF}{CD}[/tex]Let's make this problem simpler by incorporating only 2 variables instead of 3. Let's say that the total distance between the two poles is distance d. Instead of z, let's call it d - y.
Substitute known values or variables into the proportions.
[tex]\displaystyle \text{Equation I: } \frac{d-y}{d} = \frac{x}{6}[/tex][tex]\displaystyle \text{Equation II: }\frac{y}{d}= \frac{x}{12}[/tex]Cross-multiply and simplify Equation I.
[tex]6(d-y)=dx[/tex] [tex]6d-6y=dx[/tex]Cross-multiply and simplify Equation II.
[tex]12y=dx[/tex]We now have two equations that are equal to dx, so we can set them equal to each other.
[tex]6d-6y=12y[/tex]Add 6y to both sides of the equation.
[tex]6d=18y[/tex]Divide both sides of the equation by 6.
[tex]d=3y[/tex]We can substitute this value of d back into either Equation I or II. I am going to substitute d into Equation II.
[tex]\displaystyle \frac{y}{3y} = \frac{x}{12}[/tex]Cross-multiply and simplify the equation.
[tex]12y=3xy[/tex]Divide y from both sides of the equation.
[tex]12=3x[/tex]Divide both sides of the equation by 3.

A golf cart priced at $5,600 was on slae for 20% off.The sales tax rate is 6%.What is the sale price of the golf cart,including tax?
Answers
Answer:
$4748.80
Step-by-step explanation:
First, find the cost with 20% off, by multiplying the price by 0.8
5600(0.8)
= 4480
Find the cost with tax, by multiplying this by 1.06
4480(1.06)
= 4748.8
So, the sale price, including tax, is $4748.80
80/100 x $5600 = $4,480 (same as 80% times $5600)
6/100 x $4,480= $268.80 (sales tax price)
$4,480+$268.80=$4748.80
