Answer:

The volume of the new prism is three times the volume of the old prism

Step-by-step explanation:

To carry out this problem we have to invent 3 variables that represent length, width and height

w = width

h = height

l = length = 19cm

Now we have to do the equation that represents the calculation of the volume of the prism

v = w * h * l

v = w * h * 19

v = 19hw

assuming the length is tripled

v = w * h * 3l

v = w * h * 3 * 19

v = 57wh

To know the volume of the new prism with respect to the previous one, we simply divide the volume of the new prism by the previous one.

57hw / 19hw = 3

The volume of the new prism is three times the volume of the old prism

Answer:

Step-by-step explanation:

The formula for determining the volume of a rectangular prism is expressed as

Volume = length × width × height

The volume of the original prism is 19 squared cm. Therefore, the height of the original prism is

H = 19/LW

if the length of the prism is tripled and the other dimensions stay the same, the height of the new prism would be 3H, the volume of the new prism would be

19 × 3 = 57 squared cm

Solve: 3(2x+1)-2(x+5)-5(5-2x)=16 value of x?​
makvit [3.9K]

Step-by-step explanation:

3(2x + 1) - 2(x + 5) - 5(5 - 2x) = 16

6x + 3 - 2x - 10 - 25 + 10x = 16

6x - 2x + 10x = 16 - 3 + 10 + 25

14x = 48

x = 48/14

x = 24/7

You need to find what 11% of 4 2/5 is.

You can convert 4 2/5 to 4.4 and 11% to .11

Then just multiply them together

Rita earns $16.00 per hour. If she gets a 3% raise, what will be her new hourly wage?
Vikentia [17]
All percentages can be expressed as fractions or decimals. To find a percentage of a number, we multiply the percentage with the number. In this case:
3/100 * 16/1 = 48/100 = 0.48
Or:
0.03 * 16 = 0.48
Her new hourly wage would be $16.48

Answer:

In algebraic terms this means x-17>33

Step-by-step explanation:

to solve it x−17>33

1 Add 17 to both sides.

x>33+17

2 Simplify 33+17 to 50

x>50

Answer:

1) A 2) B 3) C 4) C 5) A 6) B

Step-by-step explanation:

1) Slope is calculated by the change in y over the change in x thus (5-3)/(2-(-1)) = 2/3

2) Since there is no change in y, there is no slope.

3) The change in x is given which is 10-2 so the change in y is y2-3. For the slope to be 3/4 y must equal 6. Therefore y2 is 9.

4) Cosine is adjacent over hypotenuse and Tangent is opposite over adjacent. Given 3/5 as A/H you can construct a right triangle with the adjacent as 3 and hypotenuse as 5. The Pythagorean theorem says the adjacent squared plus the opposite squared is equal to the hypotenuse squared.

3^2 + O^2 = 5^2

O=4

Therefore TanP is 4/3

5) Pythagorean theorem again. \sqrt{3} ^2 +\sqrt{3} ^2= H^2 Therefore your hypotenuse is equal to \sqrt{6}

6) Csc is the inverse of the Sin function. So it becomes 5/4.
