A construction worker fills a mold with concrete. This solid figure represents the mold.
What is the volume of the concrete that fills the mold?
Answer:
volume = 338 x 20 = 6760 cm^3
Step-by-step explanation:
large rectangular top area = 14 x 22 = 308 cm^2
small rectangular top area = 6x5 = 30 cm^2
total top area = 308 + 30 = 338 cm^2
volume = 338 x 20 = 6760 cm^3

Answer:
4 red marbles and 6 blue marbles is the correct answwer
Step-by-step explanation:
Answer:
A.) 4 red marbles and 6 blue marbles
Step-by-step explanation:
If you times 2 x 2 then you will get 4
If you times 3 x 2 then you will get 6
And since the ratio is red : blue
2 : 3 is equivalent to 4 : 6
Just like [tex]\frac{2}{3} = \frac{4}{6}[/tex] they are the same thing.
if you were to do a fraction graph, 2 of the 3 [tex]\frac{1}{3}[/tex] bars would be the same length of 4 [tex]\frac{1}{6}[/tex] bars:
Write the answer in simplest form.
1/6 / 1/3

You buy a flight to California for $305.72. The tax is 7.65%. What is the final cost of the ticket?
Show work and use method
Answer:309.83
Step-by-step explanation:
The final cost of the flight ticket $329.10758.
Given that, the cost of flight ticket is $305.72 and tax=7.65%.
What is the tax?Taxes are mandatory contributions levied on individuals or corporations by a government entity—whether local, regional, or national. Tax revenues finance government activities, including public works and services such as roads and schools, or programs such as Social Security and Medicare.
Now, tax = 7.65% of 305.72
= 7.65/100 × 305.72
=0.0765 × 305.72
=$23.38758
Total cost = 305.72+23.38758
=$329.10758
Therefore, the final cost of the flight ticket $329.10758.

Answer:
x = 2
Step-by-step explanation:
You can make a ratio out of this!
2 / x = (x+1) / 3
1. Cross multiply^
2. 2 * 3 = x (x+1)
3. 6 = x^2 + x
3. x^2 + x - 6
4. Factor^
5. (x-2)(x+3)
6. x - 2 = 0 turns into x = 2
7. x + 3 = 0 turns into x = -3
8. There's not way to measure -3 yet, so you are left with x = 2

Sudha earns ` 189 in a day and Radha earns ` 112 in a day. About how much will each of them earn in 30 days
Answer:
the sudha and radha earns 5,670 and 3,360 respectively
Step-by-step explanation:
Since in the question it is mentioned that
Sudha earns 189 in a day
And, radha earns 112 in a day
so in 30 days, sudha earns
= 189 × 30 days
= 5,670
And, radha earns
= 112 × 30 days
= 3,360
Therefore the sudha and radha earns 5,670 and 3,360 respectively

Which value for b makes the equation b/4 =12 true?
48 would be in that place because 12 x 4 would get you to 48, which means that 48 is the answer for this one. Hope this helped. I had to edit the answer out because it glitched, sorry :/
The value for b that makes the equation b/4 = 12 true is b = 48.
We have to find the value for b that makes the equation b/4 = 12 true, we can solve for b by multiplying both sides of the equation by 4.
b is the variable in the equation.
b/4 = 12
Multiply both sides by 4:
4 × (b/4) = 4 × 12
This simplifies to:
b = 48
Therefore, the value for b that makes the equation b/4 = 12 true is b = 48.
