<h2>The value of x = 36</h2>

Step-by-step explanation:

We have,

x, 45, 40 and 50 are in a proportion.

x : 45 : : 40 : 50

To find, the value of x = ?

We know that,

a : b : : c : d

Product of means = Product of extremes

a × d = b × c

∴ a × d = x × 50

Also,

b × c = 45 × 40

∴ x × 50 = 45 × 40

⇒ x = \dfrac{45 \times 40}{50}

⇒ x = \dfrac{45 \times 4}{5}

⇒ x = 9 × 4 = 36

∴ The value of x = 36

32 ounces of water in a glass someone drink 55% how many ounces left in glass
borishaifa [10]
Hello!

Convert 55% to a decimal by dividing it by 100.

55 ÷ 100 = 0.55

Next, multiply the total amount of ounces of water by this decimal.

32 × 0.55 = 17.6

Finally, subtract the amount of ounces that person drank from the total number of ounces before they drank.

32 - 17.6 = 14.4

ANSWER:

14.4 ounces of water are left in the glass.

Answer:

Y' = (-2, 4\frac{2}{3})

Step-by-step explanation:

Given

Y = (-3,7)

Scale\ Factor = (\frac{2}{3}x,\frac{2}{3}y)

Required

Determine Y'

Y' can be solved by multiplying the scale factor by Y

i.e.

Y' = Scale\ Factor * Y

For, the x coordinates.

Y' = \frac{2}{3}x

Where

x = -3

Y' = \frac{2}{3} * -3

Y' = \frac{-6}{3}

Y = -2

For the y coordinates:

Y' = \frac{2}{3}y

Where

y = 7

Y' = \frac{2}{3} * 7

Y' = \frac{14}{3}

Y' = 4\frac{2}{3}

Hence:

Y' = (-2, 4\frac{2}{3})

What is the value of x?<br><br> enter your answer in the box
antiseptic1488 [7]

Answer:

2(x+10) = 3x-30          (reason: vertical angles are congruent)

2x+20 = 3x-30

20 = 1x-30

1x = 20+30

1x = 50

x = 50
