Volumes of rectangular Prisms and Cylinders (PLEASE HELP)

Answer:

67.6

Solving Steps:

=> 2x³ + 3.4y

=> 2(3)³ + 3.4(4)

=> 2(27) + 13.6

=> 54 + 13.6

=> 67.6

Hey there!

1/2x^3 + 3.4y

= 1/2(3)^3 + 3.4(4)

= 1/2(3 * 3 * 3) + 3.4(4)

= 1/2(9*3) + 3.4(4)

= 1/2(27) + 3.4(4)

= 27/2 + 3.4(4)

= 13.5 + 13.6
= 27.1

Therefore, your answer is: 27.1

Good luck on your assignment & enjoy your day!

Answer:

3 1st class tickets

5 coach tickets

Step-by-step explanation:

Quantity:: C + F = 8

Value:: 380C + 1180F = 5440

Modify;:

1180C + 1180F = 1180*8

380C + 1180F = 5440

Subtract and solve for "C"::

800C = 4000

C = 5 (# of coach tickets)

Let x = number of 1st class tickets

8-x = number of coach tickets

and

She bought 3 1st class tickets

She bought 5 coach tickets

Answer:

18 cups

Step-by-step explanation:

Because there is 4 cups in a quart, we can turn 5 1/2 or 5.5 quarts into 22 cups:

5 1/2 or 5.5

( 5 x 4) + (0.5 x 4) = 22

Since we need to find how many cups were used, that is x. Because 22 cups is the total amount of cups and 4 is the amount remaining then the equation would look like this:

x + 4 = 22

Finally you solve to get:

x = 18 cups

Answer:

Surface area = 2(3(5) + 3(6) + 5(6))

= 2(15 + 18 + 30)

= 2(63) = 126 ft²

Cost of wallpaper per square foot:

$504/126 ft² = $4/ft²

Answer:

Result: $26.46

Steps:

$24.50 (increase) + 8% = $26.46

24.50 x (1 + 8%) = 24.50 x (1 + 0.08) = 26.46

I'm truly sorry if my math is incorrect.

Bye, have a great day/night  :)

Answer:

$26.46

Step-by-step explanation:

1 example $24.50*(108%)

24.5*1.08

= $26.46

2nd example 24.5+1.96=26.46

Also 8% of 24.5 is 1.96

Have A Great Day!! Hope this help you out! Glad its Thursday. I tried my best of helping you on this problem. Hope it was right if not I'm sorry I tried my best of figuring it out.

Answer:

C. y = 3x + 14

Answer:

A. y = 3x – 10

Step-by-step explanation:

We have equation of line passing through two points (x1, y1) and (x2, y2) as,

(y - y1) = [(y2 - y1)/(x2 - x1)] (x - x1)

(y + 4) = [(2 + 4)/(4 - 2)] (x - 2)

(y + 4) = (6/2)(x - 2)

(y + 4) = 3(x - 2)

3x - y - 10 = 0 --- (1)

Now, slope-intercept form of line is y = mx + c

Rearranging equation (1) ⇒ y = 3x - 10

Therefore, the required equation is y = 3x - 10

Answer:

the answer is D. 7 1/30

Step-by-step explanation:

first make them into improper fractions:

21/5 and 17/6

second find a common denominater (im using 30) and multiply so they have 30 as the denominater:

126/30 and 85/30

third add the improper fractions:

126/30 + 85/30 = 211/30 and as a mixed number it would be 7 1/30

Answer:

D. 7 1/30

Step-by-step explanation:

4 1/5 + 2 5/6=

The first thing we notice here are the fractions, whenever working with fractions, the first thing to do to make your life easier is to find the common denominator for the fractions. What's a common denominator?? a common denominator is when two fractions can have the same number on the bottom. We know that 5 times 6 gives you 30, so 30 can be our common denominator.

4 1/30 + 2 5/30 =

ok so, we changed our denominator, but now what? since we changed the denominator, this also affects the numerator (the numbers on the top). to fix this, we have to do the same to the numerator as we did to the denominator. to change 5 into 30, we multiplied it by 6, this means we also have to multiply 1 by six, 6/30. Don't forget the other fraction too! Since we multiplied 6 by 5 to get 30, we also have to multiply 5 by 5, 25/30.

4 6/30 + 2 25/30 =  

now that the fractions have the same denominator, we can just go ahead and add the digits and numerators!

we know that 4 + 2 = 6, so we can remove them and put 6 at the end of the equation

6/30 + 25/30 =  6

but we aren't done yet, now we add 6 + 25 which gives us 31, out of 30

wait! 31/30? that doesn't sound right. 30 out of 30 automatically gives us a 1, so we can add that to the 6 we got earlier, 6 + 1 = 7. Since we are left with 1/30 we will add this to the final answer: 4 6/30 + 2 25/30 =  7 1/30

Answer:

It is B) 11/4 - 6/4 = 5/4

Step-by-step explanation:

First off 2 3/4 as an improper fraction is 11/4 and the rest are improper fractions to

Next we know how much Maria poured in witch is 1 2/4 = 6/4. So Ansley poured in the rest.

Then we do 11/4 - 6/4 = 5/4 and that is your answer

Answer:

16

Step-by-step explanation:

Line 1: ◄ + ◄ + ◄ = 30

3◄ = 30

◄ = 10

The triangle equals 10.

Line 2: ◄ + ◘ + ◘ = 18

10 + 2◘ = 18

2◘ = 8

◘ = 4

The square equals 4.

Line 3: ◘ - ○ = 2

4 - ○ = 2

-○ = -2

○ = 2

The circle equals 2.

○ + ◄ + ◘ = 2 + 10 + 4 = 16

Answer: 16

Answer:

25

Step-by-step explanation:

8 x 4 / 2 gets you the area of the big triangle, which is 32 / 2 = 16

1 x 8 for the rectangle, so far you're at 16 + 8 = 24

The tiny triangles are half the squares so add them together ( 1/2 + 1/2) to get 2/2 = 1/1

add them together to get 24 + 1 = 25

You can also do it as if you take the big triangles and add them together to get a square, you get a 4 x 4 square

Then you have the 1 x 8 rectangle

do the same thing with the tiny triangles as the big triangles, and you get 1

(4 x 4) + (1 x 8) + 1

16 + 8 + 1

24 + 1 = 25

Solution:

We know that:

Step by step calculations:

1. Substitute the angles in the equation "∠A + ∠B + ∠C = 180" to find ∠C:

2. Substitute ∠C in the equation "∠C + n = 180" to find n:

Sum of two interiors=exterior

[tex]\\ \rm\Rrightarrow m<A+m<B=n[/tex]

[tex]\\ \rm\Rrightarrow 38+90=n[/tex]

[tex]\\ \rm\Rrightarrow n=128°[/tex]

Option B

Answer:

80 units

Step-by-step explanation:

Start with the rectangle of 8×6 which is 48.

Then start with a base, 2×6=12 and add 4, 2 per triangle. One base equals 16 and because it's 2 bases multiply by 2 equals 32.

32+48=80

Answer:

2 11/12

Step-by-step explanation:

Answer:

A power of 10 is as many number 10s as indicated by the exponent multiplied together.

Step-by-step explanation:
Thus, shown in long-form, a power of 10 is the number 1 followed by n zeros, where n is the exponent and is greater than 0; for example, 106 is written 1,000,000.

Answer:10 of the power means you add on the zeros

Step-by-step explanation:

say if your question says 10 to the 4 power it would be 10,000 because the power stands for the zeros in your answer.
