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

1. observe the following tables and find if x and y are directly proportional:
Give answer plzz
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=we will get the answer again
1/2.
all the coordinates is proportional in this form it is all will get the answer one by two so this x -axis and y-axis are directly proportional

y = 5x - 9
y - 5x = 4
(3,2)
no solution
an infinite number of solutions
Answer:
(3, 2)
2 = 5 x 3 - 9
= 15 - 9
= 6
2 is not = 6
y = 5x - 9
y - 5x = -9
y - 5x = 4
Use elimination
-15
ANSWER: So there are no solutions
what is the value of x?
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

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.
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

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?
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

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.
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)
