1. Find the volume of each cylinder ( use = 3.14 )

Answer:

-1.3125

Step-by-step explanation:

-16(d+1) = 20

-16d - 1 = 20

       +1    +1

-16d = 21

d = -1.3125

or -1.3

Answer:

$10t=m

Step-by-step explanation:

If for each hour is $10.

She would earn the number of  hours times $10.

Example: She did babysitting for 4 hours this weekend. The equation is $10(4)=m or $10 x 4 = m.  m=40

Answer:

slope: 2/3 or 0.6666...

Step-by-step explanation:

find two points on the line : (1,2) and (0,-2) and do rise over run. Rise = 2 and Run = 3, so you put it in rise over run form. Rise/Run = 2/3. The graph is positive.

Answer:

200 miles

Step-by-step explanation:

Given data

Rapid Rental Car

charges a $55 rental fee

$20 for gas, and

$0.65 per mile driven

let the number of miles be x, the total charges y

y=55+20+0.65x

y= 75+0.65x----------1

Capital Cars

charges $55 for rental and gas and

$0.75 per mile.

let the number of miles be x, the total charges y

y=55+0.75x

y= 55+0.75x----------2

Required

The number of miles driven before the two Rental companies charge the same amount

equate 1 and 2

75+0.65x= 55+0.75x

collect like terms

75-55= 0.75x-0.65x

20= 0.1x

x= 20/0.1

x= 200miles

Hence the distance will be 200 miles for the charges to be the same

Answer:

8 + 4 = 12 x 7 = 84m

Answer:

An irrational number is a number that can not be written as the quotient of two integer numbers.

Then if we have:

A = a rational number

B = a irrational number.

Then we can write:

A = x/y

Then the product of A and B can be written as:

A*B = (x/y)*B

Now, let's assume that this product is a rational number, then the product can be written as the quotient between two integer numbers.

(x/y)*B = (m/n)

If we isolate B, we get:

B = (m/n)*(y/x)

We can rewrite this as:

B = (m*y)/(n*x)

Where m, n, y, and x are integer numbers, then:

m*y is an integer

n*x is an integer.

Then B can be written as the quotient of two integer numbers, but this contradicts the initial hypothesis where we assumed that B was an irrational number.

Then the product of an irrational number and a rational number different than zero is always an irrational number.

We need to add the fact that the rational number is different than zero because if:

B is an irrational number

And we multiply it by zero, we get:

B*0 = 0

Then the product of an irrational number and zero is zero, which is a rational number.

Answer:

=−259x−2y+24

Step-by-step explanation:

Distribute:

=−12x+4y+−6y+10x+−255x+(−2)(x)+(−2)(−12)

=−12x+4y+−6y+10x+−255x+−2x+24

Combine Like Terms:

=−12x+4y+−6y+10x+−255x+−2x+24

=(−12x+10x+−255x+−2x)+(4y+−6y)+(24)

=−259x+−2y+24

Answer: 4(2x - 5)

Step-by-step explanation:

factors of 8 : (2, 2), 2

             20 : (2, 2), 5

Therefore the GCF is 2*2 = 4

8x/4 = 2x and -20/4 = -5

4(2x - 5) = 8x - 20

Step-by-step explanation:

Given

5x + 2y = 16 .....i)

x + 2y = 4 .....ii)

Subtracting equation I) and ii) we get

5x + 2y = 16

x + 2y = 4

- - -

4x = 12

x = 3

Putting x = 3 in equation ii)

3 + 2y = 4

2y = 4 - 3

y = 1/2

x =3 and y = 1/2

Hope it helps :)

Correct question is;

Which of these expressions is equivalent to log (9^2)?

Answer:

D: 2•log 9

Step-by-step explanation:

From log rules, we know that;

log(a^n) = n•log(a)

Applying that rule to this question, we can simplify log (9^2) as;

log (9^2) = 2•log 9

Looking at the options, the correct one is Option D

Answer:

45/8 or 5 5/8

Step-by-step explanation:

2 1/4. 2 times 4 is 8 plus 1 is 9 (9 over 4 (9/4)). 2 1/2. 2 times 2 is 4 plus one is 5. (5 over 8 (5/2)). 9/4 x 5/2. 9 times 5 is 45, 4 times 2 is 8.  you get the improper fraction 45/8. 45 simplified is 5 5/8. hope i helped.

Answer:

45/8 or 5 5/8

Step-by-step explanation:

When multiplying fractions, it ALWAYS so much easier to make them into improper fractions (for me at least). When doing this, multiply the denominator to the whole number and add the numerator and keep the denominator the same. So, for 2 1/4, you could use the equation 2(4) + 1 = x/4. You should get 9/4. Doing this for the other mixed fraction, you get 5/2.

Multiplying fractions is pretty straightforward after that. You don't have to change the denominators to match each other like you do when adding, instead you just multiply straight across. Multiply both of the numerators and then the denominators.

                                      Numerators: 9 x 5 = 45

                                      Denominators: 4 x 2 = 8

So, you get 45/8. If you're wanting a mixed number fraction, just divide 45 by 8. 8 goes into 40 5 times, and you get a left over number 5. Therefore, as a mixed fraction you get 5 5/8.

I don't know how you wanted me to show my work, but I tried the best I could to explain.

Answer:

3.2

Step-by-step explanation:

ABCD and JKLM are similar. To find the x, first find the ratio for all of the sides.

AD and JM are similar --> 2.4 / 3 = 0.8

BC and KL are similar --> 4 / 5 = 0.8

DC and ML are similar --> 2.4 / 3 = 0.8

AB and JK are similar --> 4 × 0.8 = 3.2

Hope this helps, thank you :) !!

Answer:

red) area = 59.2 km²

Step-by-step explanation:

area of bottom 4 x 4 = 16

area of 4 sides = 4 (1/2)(4)(5.4) = 43.2

16 + 432 = 59.2 km²

Answer:

Step-by-step explanation:

lateral area = 2(base)(slant height) = 2·4·2 = 16 km²

base area = base² = 4² = 16 km²

surface area = 16 + 16 = 32 km²

Answer:

y =-5x + 7

Step-by-step explanation:

y = -5x + 4

Slope = -5

Parallel lines have same slope

Slope of the parallel line to this line = -5

(1 , 2)

y -y1 =m(x - x1)

y - 2 = -5(x - 1)

y -2 = -5x + 5

   y = -5x + 5 + 2

  y = -5x + 7

Step-by-step explanation:

Answer:

Jessica needs 2 cases of 12 girls scout cookies plus 2 extra boxes

Step-by-step explanation:

Number of boxes sold = 26

Cases of 12 plus extra boxes needed

Number of cases of 12 needed :

Number of boxes sold / 12

= 26 /12

= 2 remainder 2

Hence, Jessica needs 2 cases of 12 girls scout cookies plus 2 extra boxes

Step-by-step explanation:

(2x-5) = 3(4+x/2) then solve for x.

2x-5 = 12 + (3/2)x

2x-(3/2)x = 17

x/2 = 17

x=34

Checking the left side, (2x-5) = 2(34) - 5 = 63.

Checking the right side, 3(4+(34/2)) = 3(4+17) = 3(21) = 63.
