what is the value of x?

Answers

Answer:

x = 6

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{FG}{MN}[/tex] = [tex]\frac{GH}{NP}[/tex] , substitute values

[tex]\frac{12}{x}[/tex] = [tex]\frac{20}{10}[/tex] = 2 ( multiply both sides by x )

12 = 2x ( divide both sides by 2 )

6 = x

A≈21.46
First you find the area of the square

A=a^2 which is
=10^2
A=100

Then you find the area of the circle
A=πr^2
= π(5)^2
A≈78.54

Now you subtract the 78.54 from 100 to get 21.46

So we need to find the unit rate (the denominator is 1). Divide 18 by 3 to find the amount of miles in 1 day. 18/3=6. So m=6d. To find the number of miles in 10 days, you can make an equation 1/6=10/x. x=60, so the number of miles Henry will bike in 10 days is 60 miles. Repeat with the second chart

yes here x and y are directly proportional when looking at the x-coordinate

Step-by-step explanation:

here,

x1=7, y1=14

x/y=7/14

=1/2.

when considering the second coordinates,

X2=9/18

Step-by-step explanation:

Her equation is wrong. It should be
(20)(0.85)(1.06) = 18.02

20 x 0.85 = 17, the price after the 15% discount. Cat’s equation added 15%.

You could also do 20 x 0.15 = 3, the amount of the discount, and subtract from $20.

17 x 0.06 = 1.02, the amount of tax
Total cost = 17 + 1.02 = 18.02
This tax part is represented by the 1.06 in the equation. The sale price + 0.06 of that price in tax.

Find the perimeter of an isosceles triangle whose base is 16 cm and whose height is 15 cm.

Answers

Answer:

50 cm

Step-by-step explanation:

The altitude from the vertex to the base bisects the base and divides the triangle into 2 right triangles.

Using one of the right triangles with legs 8 and 15 , then hypotenuse h is

h² = 8² + 15² = 64 + 225 = 289 ( take the square root of both sides )

h = [tex]\sqrt{289}[/tex] = 17

The 2 congruent sides of the isosceles triangle are 17 cm

Then the perimeter P is

P  = 17 + 17 + 16 = 50 cm

You are selling candy bars for
$2.50 each. The cost of those
candy bars was $1.25 plus a setup
fee of $200 for manufacturing.

1) what is the profit from selling 220 candy bars?

Answers

Answer: 75 dollars

Step-by-step explanation:

220 times 2.5 is 550 which means you make 550 dollars. However, it cost 4575 dollars to make the candy bars because 220 times 1.25 is 275 and 275+200 is 475. You have to subtract 475 from 550 to get your answer which is 75 dollars.

Answer:

$75

Step-by-step explanation:

multiply total bars by cost 275+ 200=475

multiply total bars by sale price =550

Pairs of shoes are manufactured for $24. They are sold to a warehouse with a mark-up of 15%. The warehouse sells the shoes to a distributor after charging a holding fee of $10 per pair. The distributor sells them to ‘Fine Shoes’ for a percentage profit of 12%. The store then marks them up by 30%.


a. Determine the price of a pair of shoes if you buy it from one of the ‘Fine Shoes’ stores (round to the nearest 5 cents). Show working out.

Answers

Answer: ‭$54.75

Step-by-step explanation:

The price the shoes are sold to the warehouse is:

= 24 * ( 1 + 15%)

= 24 * 1.15

= $27.60

The price the warehouse sells it is:

= 27.60 + 10

= $37.60

Price distributor sells is:

= 37.60 * 1.12

= $42.112

Fine shoes will then sell at 30% profit:

= 42.112 * 1.3

= $‭54.7456‬

= ‭$54.75

The formula for centripetal acceleration, a, is given by this formula, where v is the velocity of the object and r is the object’s distance from the center of the circular path:
a=v^2/r
.

Solve the formula for r.

Answers

Answer:

Step-by-step explanation:

For this case we have the following equation:

a = v ^ 2 / r

From here, we must clear the value of speed.

We have then:

v ^ 2 = a * r

v = root (a * r)

Answer:

the formula for the velocity is:

v = root (a * r)
