Answer: A - 30 cubes

B - Volume of prism =  feet³

Step-by-step explanation: We are given that the dimensions of the rectangualr prism is,

Length =  =  feet

Width = 1 foot

Height =  =  feet

Thus, the volume of the prism = Length × Width × Height

i.e. Volume of the prism =  × 1 ×  =  feet³

Now, the side of the cube =  foot each.

Volume of the cube =  =  feet³

I did number 6 to give you an idea of what you have to do. First find simplify the top and bottom and reduce!

Hope it helps! Comment if you have any questions!

Yes

By tripling the height, you would triple the volume.

Also , By tripling the radius, you would increase the volume to nine times the original

The simplest ratio of circles to square is  2:3.

The numerical relationship between two values that demonstrates how frequently one value contains or is contained within another.

There are 6 circles and 9 squares.

The simplest ratio;

circles : squares,

Substitute the value of circles and squares;

circles : squares = 6:9

Simplifying,

circles : squares = 2:3

Therefore, the simplest ratio of circles to square is 2:3.

Answer:

for the third problem a = cb

for the 4th problem x = 5a + g

for the 2nd problem p = (q - 3r) / 4

for the first problem x = (-9 - z) / y

for the last problem: b = 15

A = 1/2 bh

75 = 1/2 b(10)

75 = 1/2 10b

multiply both sides by 2

150 = 10b

divide by 10 from both sides

15 = b

b = 15

Answer:

-9 - z/ y

Answer:

Let's say the set of downs starts at the 20 yard line (maybe the kicking team kicked deep, the receiving team took a knee and so play starts at the 20).

Ok - we're at the 20. First down - they advance 5 yards. So we're now at the 25. We can write that mathematically as:

20

+

5

=

25

So the second play they get sacked deep and lose 6 yards. So we subtract 6:

25

−

6

=

19

So what's the change in yardage for the 2 plays? We are on the 19 and started at the 20, so we can write:

19

−

20

=

1

and this makes sense because we know we advanced 5 and fell back 6:

Answer:

11. x = -16

12. k = 6

13. x = -19

14. x = -6

15. x = -20

16. Combining like terms isn't to be used on this type of problem. I'm sorry, can you guess on this one?

17. x = 19

18. n = -10

19. b = 11

20. n = 4

21. r = -6

22. n = -4

Again super sorry about question 16 :(

Answer:

Step-by-step explanation:

11) -1= x/16

x= -16(because when dividing a negative and positive number the answer is always a negative.

12) 7=1+k

k=7-1

k=6

13) x-6=-25

x=-25+6

x=-19

14) -8x=48

x=48/-8

x= -8

15) x/10=-2

x=10*-2

x=-20

Answer:

               •₁ same side interior angles  

               •₂ m∠1 = 78°,  m∠2 = 102°

               •₃ oars are parallel, conversed the same side interior angles theorem      

Step-by-step explanation:

•₁

The edge of the kayak is a transversal of lines created by oars. The angles are on the same side of transversal and between the oar-lines (inside the area between lines) so they are same side interior angles (or: consecutive interior angles)

•₂  

x = 10

m∠1 = 6x + 18 = 6•10 + 18 = 78

m∠2 = 9x + 12 = 9•10 + 12 = 102

•₃

The measures of angles 1 and 2 add to 180° (102+78=180) so they are suplementary angles. It means the oar-lines are parallel.

Based on:

Conversed the Same Side Interior Angles Theorem: If two lines are cut by a transversal and the same side interior angles are supplementary, then the lines are parallel.

Answer:

The sum of two consecutive number is 55'which is the largest number? So the numbers are 27 and 28.

Step-by-step explanation:

If we say [tex]x[/tex] is the first number, then the next consecutive number will be [tex]x+1[/tex].

Using this, we can make an equation.

[tex]x+(x+1)=55[/tex]

[tex]2x+1=55[/tex]

[tex]2x=54[/tex]

[tex]x=27[/tex]

And so we know that the two consecutive numbers are 27 and 28.

Hope this helps.

Step-by-step explanation:

Changing Percents to Decimals

The word percent means "per 100."  20% means 20 out of 100, or 20/100.   67% means 67 out of 100, or 67/100.  So to change a percent to a decimal, you simply divide the percentage number by 100.  When you divide by 100, the decimal just moves over 2 places to the left.

Changing Percents to Fractions

Remember, the word percent means "per 100."  This means you can change a percent to a fraction by dividing by 100.  Don't stop here though, make sure to simplify the fraction if possible.  Look to see if the numerator and denominator can be divided by the same number.

Changing Decimals to Fractions

First, figure out the place value of the last digit on the right.  Is it in the tenths place? Hundredths? Thousandths?  Use the place value to write the decimal as a fraction over 10, 100, 1000, etc. Then simplify the fraction if possible.

Remember, the first place to the right of the decimal is the tenths place.  The second place is the hundredths, then thousandths, ten thousandths, and so on.

Answer:

x=6 and y=14

Step-by-step explanation:

First lets solve x

We substitute y for 0

So then this is how it turns out:

7*x+3*0=42

To find x you divide 42 and 7 and it becomes 6

Then lets solve y

We substitute x for 0

So then this is how it turns out:

7*0+3*y=42

To find y you divide 42 and 3 and it becomes 14.

THUS x=6 AND y=14

Divide the total amount of money you have by the cost of one package of blueberries.

If one package of blueberries is $5, and you have $15, divide 15 by 5

15 ÷ 5 = 3

You can buy 3 packages of blueberries with $15 dollars.

--

In a proportional relationship, the ratios of the x and y variables are equivalent.

To find out if this relationship is proportional, take two of the points and convert them to fractions (x over y).

(1, 5) & (3, 15) ⇒ [tex]\frac{1}{5}[/tex] & [tex]\frac{3}{15}[/tex]

Divide the numerators and denominators by each other. If they both equal the same number, the relationship is proportional.

3 ÷ 1 = 3 ,,, 15 ÷ 5 = 3

Yes, the relationship is proportional.
