Answer:

x = 30

Step-by-step explanation:

[tex] \triangle JLK\sim\triangle PQR[/tex] (given)

[tex] \therefore \frac{JL}{PQ}=\frac{LK}{QR} [/tex]

(corresponding sides of similar triangles)

[tex] \therefore \frac{20}{x}=\frac{22}{33} [/tex]

[tex] \therefore \frac{20}{x}=\frac{2}{3} [/tex]

[tex] \therefore x=\frac{20\times 3}{2} [/tex]

[tex] \therefore x=\frac{60}{2} [/tex]

[tex] \therefore x=30 [/tex]

Or using scale factor:

Scale factor = 33/22 = 3/2

x = 20*3/2

x = 10*3

x = 30

if a number × is increased by 11,the result is 35.What is the number?

Answers

Answer:

Step-by-step explanation:

Equation: x + 11 = 35

1. Subtract 11 from both sides

x + 11 = 35

-11 -11

x = 24

Answer:

x is 24

Step-by-step explanation:

Let's write it down as an equation

If number x is increased by 11, we'll write is as x+11 and the result of that is 35, so x + 11 = 35

x + 11 = 35 implies that

x = 35 - 11

35 - 11 = 24

x = 24

Answers

Answer:

1. a2. b3. b4. b5. 22

Explanation:

n²-49=0

n=√49

n=7

x²+64=0

x=√64

x=8

if A=144x²

l = √A

l = √(144x²)

l = 12x

b = (24×2)/3b

b = 48/3b

b = 16/b

b² = 16

b = √16

b = 4 in (-4 is correct in algebra but there's no negative lengths in geometric shapes)

x²+z = 103

x² = 103-z

x = √(103-z)

for x = -9 and 9 (103-z) must equal 81

z = 103 - 81 = 22

x = √(103-22)

x = √81

x = -9 , 9

i get a 25% discount (means decrease) at macys store. if i find a dress i like for $80, how much will i have to pay for it?

Answers

Answer:

you will pay $60

Step-by-step explanation:

25% (1/4) of 80 is 20

subtract 20 from the total (80)

80 - 20 = 60

$60

Answer:

Step-by-step explanation:

So if you get 25% off, you're basically paying 75%.

So first, convert the percentage to a decimal:

75% = 75/100 = 0.75

Now just multiply the decimal by the total cost:

80$ (0.75) = $60

A cylinder has a volume of 8792 cubic units. If the height is 7 cubic u it’s which of the following is the radius

Answers

Answer:

20 units

Step-by-step explanation:

Volume of a cylinder = πr²h

V = πr²h

height, h = 7

V = π * r² * 7

V = 8792

8792 = 21.991148 * r²

r² = 8792 / 21.991148

r² = 399.79722
