You just need to foil. 2x times 4x times 2x times 36 times 24 times 4x times 24times 36. then solve.
Answer 2
Hey there! Hello!

For this problem, you need to use the distributive property to expand the variables into one equation. In my attachment, I'll show you how to do this.

If you need to then factor out the equation back into two binomials, you could either do it the way I show you, or you could just factor out the GFC's of both binomials, 2 and 4, to get 8. Either way, it's good to know how to do these steps. If the "re-factoring" step isn't necessary for your question, the second line down in the lower portion of my work. 

I hope this helped you out! Feel free to ask me any additional questions if you have any. :-)

Antoine and 3 friends divide some pennies evenly among themselves. Each friend separates his pennies into 3 equal stacks with 5 pennies in each stack. write a multiplication sentence that shows

Answers

Answer:

4 × ( 3 × 5 ) = 60

Step-by-step explanation:


Answer:

4 × (3 × 5) = 60

Step-by-step explanation:

Total number of persons including Antony = 4

Number of stacks separated by each friend = 3

Number of pennies in each stack = 5

Number of pennies in all 3 stacks of one friend = 3 × 5

Number of pennies in all 3 stacks of 4 persons = 4 × (3 × 5) = 60

Hence, the multiplication sentence is 4 × (3 × 5) = 60.

what is the answer to 38-19+12

Answers

To solve the expression 38-19+12, we subtract 19 from 38, resulting in 19, and then add 12 to get an answer of 31.

To solve the expression 38-19+12, we should follow the proper order of operations, which in this case, simply requires us to perform the subtraction and addition in the sequence they appear from left to right. First, subtract 19 from 38, then add 12 to the result.

Subtract 19 from 38, which equals 19 (38 - 19 = 19).

Add 12 to the result from step 1, which gives us 31 (19 + 12 = 31).

Therefore, the answer to the expression is 31.

Phil is riding his bike he writes 42 miles in 4 hours whats 52.5 miles in 5 hours and 63 miles and 6 hours find the constant of proportional and write an equation to describe the situation let X represent the #of hours.

Answers

Answer:

Step-by-step explanation:

The constant of proportionality (known as "speed" in this case) is 12.5 miles per hour. 

d= 12.5 x t 

To find the constant of proportionality, divide one value in each pair by the other. If this relationship is a true direct proportionality , when you repeat these for every pair, your will come up with the same value:

For example

25miles÷2hours=12.5mileshour

A direct proportionality will always result in an equation that resembles this:

y=kx

where y and x are the related quantities and k is the constant of proportionality. If you draw a graph using the values you have, the graph will show a straight line the passes through the origin. The slope of this line will be the constant of proportionality. (And if the values given are real physical quantities, this constant will contain important information about the situation you are studying!)

Members of the Blade runners skating club collected $950 from fundraising activities.They want to buy Altrablade skates, which are $48 a pair. How many pairs of skates can they buy? What does the remainder represent

Answers

They can buy 19 pairs of skates, the $38 that remained is for the skating club.

Answer:

19 pairs

need 21% of $48 to buy 20th pair

Step-by-step explanation:

If the members collected $950 and they want to by Altrablade skates for $48 a pair, the amount of pairs of skates can be determine by dividing the total amount collected by the cost per skates:

[tex]950/48=19.79=19[/tex]

They can buy 19 pairs of skates by the remainder is 0.79. This represents the amount still needed to buy the 20th pair of skates. So they would need 21% of the $48 to buy a extra pair.

A filter in the shape of a cone has a diameter of 3 inches and a height of 4 inches.
How much liquid can the filter hold without it overflowing?
A) π in3
B) 3π in3
C) 12π in 3
D) 36π in3

Answers

Answer:

the correct answer in ''B''

Step-by-step explanation:


Final answer:

The cone-shaped filter with a diameter of 3 inches and a height of 4 inches can hold 3π inches³ of liquid without overflowing, which corresponds to choice B.

Explanation:

To find how much liquid can be held in a cone-shaped filter without overflowing, we use the formula for the volume of a cone, V = πr²h/3, where r is the radius, h is the height, and π (pi) is approximately 3.14. Given that the diameter of the cone is 3 inches, the radius (r) would be half of that, which is 1.5 inches. The height (h) is given as 4 inches. Plugging these values into the formula gives us:

V = π(1.5²)(4)/3 = π(2.25)(4)/3 = π(9)/3 = 3π inches³

Therefore, the cone-shaped filter can hold 3π inches³ of liquid without overflowing, which corresponds to choice B.

Which ratio forms a proportion with 18/27?
A. 1/3
B. 2/5
C. 2/3
D. 7/9

Answers

C, 2/3

18 divided by 9 equals 2

27 divided by 9 equals 3

Answer:

C. [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

The proportions are nothing but the equivalent ratios.

We  are given the proportion =  [tex]\frac{18}{27}[/tex]

We can reduce this proportion using the Greatest Common Factor (GCF).

The GCF of 18 and 27 is 9.

Therefore, dividing the numerator and the denominator by 9, we get

=  [tex]\frac{18divide9}{27divide9}[/tex]

=  [tex]\frac{2}{3}[/tex]

Therefore, the answer is C. [tex]\frac{2}{3}[/tex]

lesson 7 homework practice convert measurment unit

Answers

What is the problem? 

The correct option is d. 8 oz. can of juice is most convenient to meet this requirement.

First, let's convert 240 milliliters to ounces because the answer choices are in ounces.

1 milliliter is approximately equal to 0.0338 ounces.

So, 240 milliliters is approximately \( 240 \times 0.0338 \) ounces, which is about 8.112 ounces.

Now, let's examine the options:

a. 5 oz. can of juice: Not enough juice. It's less than the required 8.112 ounces.

b. 4 oz. can of juice: Not enough juice. It's less than the required 8.112 ounces.

c. 12 oz. can of juice: More than enough juice. It's more than the required 8.112 ounces.

d. 8 oz. can of juice: Exactly the amount needed. It matches the required 8.112 ounces.

Since the resident is supposed to have 240 milliliters of juice every 2 hours, and 240 milliliters is approximately 8.112 ounces, the closest can size that would meet this requirement without being wasteful is an 8 oz. can. The 5 oz. and 4 oz. cans would not provide enough juice, and the 12 oz. can would provide more than necessary, potentially leading to waste or overconsumption. Therefore, the 8 oz. can is the most convenient and appropriate choice.
