Answer 1

Answer:

The equivalent fractions will be 2:5 ard 12:30.

Step-by-step explanation:

Equivalent fractions simply mean the fractions that are the same or equal.

Based on the information given, the ratios that are equivalent to 4:10 will be:

4/10 = 2/5

12/30 = 2/5

20/8 = 5/2

8/30 = 4/15

Therefore, the equivalent ratios will be 2:5 and 12:30.

Answer 2

Answer:

2 : 5 and 12 : 30

Step-by-step explanation:

you can find if two ratios are equivalent by multiplying or dividing both quantities by the same number.

Hence:

4 : 10 x 3 on both sides = 12 : 30

Also

4 : 10 divided by 2 on both sides = 2 : 5

Making these equivalent

The others don’t qualify since for:

8 : 30

You would have to multiply the 4 in 4 : 10 by 2, and the 10 by 3, so basically it can’t work.

For 20 : 8

You would have to multiply the 4 in 4 : 10 by 5 and yet divide the 10 by 1.25 which definitely doesn’t work because a, the number used to multiply/divide is the same, and b, because both sides have to be multiplied or divided, not just one each.

hope this helps :D

Rewrite each equation without using absolute value for the given conditions. y=|x−3|+|x+2|−|x−5|, if x>5

Answers

Step-by-step explanation:

If x >5 then |x-3| is just x-3

|x+2| is just x + 2

|x-5| is also just x-5

so this just becomes (x-3) + (x+2) - (x-5)

Decide which measurement is greater. Place the correct symbol ( <, >, =) on the line between the measurements.
5 gallons _______ 18 quarts

1 pint 4 cups _____ 32 fl oz

3 pints ______ 8 cups

13 quarts _______ 4 gallons

4 quarts _______ 9 pints

Answers

The measurements that are greater using the correct symbol <, >, =) are:

5 gallons > 18 quarts1 pint 4 cups > 32 fl oz3 pints < 8 cups13 quarts < 4 gallons4 quarts < 9 pints

How to determine the greater measurement?

Gallons and quarts

1 gallon = 4 quarts.

So, we have:

5 gallons = 20 quarts i.e. 5 * 4

Hence,

5 gallons > 18 quarts

Pints and cups to fl oz

1 cup = 0.5 pints.

So, we have:

1 pint 4 cups = 1 pint + 2 pints

1 pint 4 cups = 3 pints

1 pint = 16 fl oz.

So, we have:

1 pint 4 cups = 16 * 3 fl oz

1 pint 4 cups = 48 fl oz

Hence,

1 pint 4 cups > 32 fl oz

Pints and cup

1 cup = 0.5 pints.

So, we have:

8 cups = 4 pints

Hence,

3 pints < 8 cups

Quarts and gallon

1 gallon = 4 quarts.

So, we have:

4 gallons = 16 quarts

Hence,

13 quarts < 4 gallons

Quarts and pints

1 quart = 2 pints.

So, we have:

4 quarts = 8 pints

Hence,

4 quarts < 9 pints

y = x² - 3

y = 1² - 3

y = 1

y = -2

(1, -2)

y = x² - 3

y = 2² - 3

y = 4 - 3

y = 1

y = x² - 3

The volume of this right trapezoidal prism is 464.75 ft³.

What is the height, x, of the prism?

Enter your answer as a decimal in the box.

x = ft

Answers

Answer:

the answer is 14.3

Step-by-step explanation:

The height of the trapezoidal prism is 12.3 feet.

Formula for finding the volume of trapezoidal prism

[tex]v = \frac{1}{2}(b_{1} +b_{2} )hl[/tex]

where,

v is the volume of trapezoidal prism

[tex]b_{1}[/tex] and [tex]b_{2}[/tex] are the bases

h is the height of trapezoidal prism

l is length of the trapezoidal prism

According to the given question

We have to find the value of x which is the length of trapezoidal prism.

And,

Volume, v = 464.75 cubic feet.

From the given figure

here,

[tex]b_{1} = 5ft[/tex], [tex]b_{2} = 8ft[/tex], [tex]h = xft[/tex], and [tex]l = 5.8ft[/tex]

Substitute all these values in the formula of the volume of trapezoidal prism

⇒ 464.75 = [tex]\frac{1}{2}[/tex] ×(5+8)(5.8)x

⇒929.5 = 13×5.8x

⇒[tex]\frac{929.5}{(13)(5.8)}[/tex] = [tex]x[/tex]

⇒ x = 12.3 feet

Hence, the height of the 12.3 feet.

64 is 4 times the difference between Sarah's age, a, and 44. Assume Sarah is older than 44.

Write an equation to determine Sarah's age (a).

Find Sarah's age.

Answers

Answer:64/4+44=a

Sarah is 60 years old

Step-by-step explanation: 64/4 =16. 44+16=60

Multiply this difference by 4, and you get 64 as the result. So:

64 = 4(a - 44)

Now you need to balance the equation. Do the same operation to both sides. To begin, divide both sides by 4.

64/4 = 4(a - 44)/4 becomes

16 = a - 44 To get variables on one side and numerals on the other, add 44 to each side.

16 + 44 = a

60 = a. Sarah is 60 years old.
