Answer:
Surface Area of rectangular prism = 94 feet²
Step-by-step explanation:
Length, l = 3 feets
Width, w = 4 feets
Height, h = 5 feets
Surface area, A of a rectangular prism is given as :
2(lw + lh + wh)
A = 2[(3*4) + (3*5) + (4*5)]
A = 2(12 + 15 + 20)
A = 2(47)
A = 94 ft²

How could you find 40% of 700 mentally? Select all that apply.
Divide 40 by you cannot find Divide 700 by Divide 700 by Divide 700 by
10, then the number 10 then 5, then
2, then
multiply the using any of multiply the multiply the
subtract 40.
result by 700. these methods.
result by 4 result by 2
Step-by-step explanation:
step 1. 40% of 700 means (40/100)(700)
step 2. (40/100)(700) = 280
step 3. mentally 7*4 = 28 so you know your answer has 28 in it
step 4. 40% of something is just less than half
step 5. half of 700 is 350. your answer is just less than that with a 28 in it. your answer is 280.
It took 4 balloons to make the duck float. The duck weighs 56 grams. With 1 balloon, how many grams could you make float?
Step-by-step explanation:
[tex] \frac{56}{4 } = \frac{x}{1} [/tex]
[tex]cross \: multiply[/tex]
[tex]4x = 56[/tex]
[tex]divide \: both \: sides \: by \: 4[/tex]
[tex] \frac{4x}{4} = \frac{56}{4} [/tex]
[tex]x = 14[/tex]
Therefore 1 balloon would make 14 grams float.

The choir raised $700 last year. This year they hope to raise 42% more money.
How much money do they hope to raise this year?
Answer:
994
Step-by-step explanation:
If the choir raised $700, and they plan to make 42% more, what you have yo do is divide 700 by 100, which will bring you to 7$ is 1% of 700. Then, you must multiple 7 by 42 (which is 294). Finally, you need to add 294 to 700, which will bring you to 994 total dollars ($) raised by the choir this year.

These marbles are placed in a bag and two
of them are randomly drawn.
What is the probability of drawing two blue
marbles if the first marble is placed back in
the bag before the second draw?
Give your answer as a rational number, reduced to
simplest terms.
1
Hint: Multiply the probability of the 1st Event by the
probability of the 2nd Event to get your answer.
Enter
Answer:
1/4
Step-by-step explanation:
There are 2 yellow, 3 red and 5 blue for a total of 10 marbles.
The probability of drawing a blue marble is 5/10 = 1/2
If the marble is replaced, then there are 10 marbles in the bag.
So, the probability of drawing another blue marble is 1/2
Now, multiply the two probabilities together to get the final probability.
1/2(1/2) = 1/4
The probability of drawing two blue marbles if the first marble is placed back in the bag before the second draw is 1/4.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
There are a total of 10 marbles in the bag.
If one marble is drawn and then placed back in the bag before the second draw, there are still 5 blue marbles in the bag,
The probability of drawing a blue marble on the first draw is 5/10 = 1/2.
Since the marble is placed back in the bag, there are still 5 blue marbles in the bag for the second draw
The probability of drawing another blue marble on the second draw is also 5/10 = 1/2.
To find the probability of drawing two blue marbles.
We multiply the probability of the first draw being blue by the probability of the second draw being blue, assuming that the first marble is replaced back in the bag:
P(2 blue marbles) = P(blue on first draw) × P(blue on second draw)
P(2 blue marbles) = (1/2) × (1/2) = 1/4
Therefore, the probability of drawing two blue marbles if the first marble is placed back in the bag before the second draw is 1/4.

Find the value of 3 in the triangle shown below.
97°
47
x whats the value of x
Answer:
x = 36
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°
The measure of two angles are given as 97° and 47°
x + 47 + 97 = 180
x + 144 = 180 subtract 144 from both sides
x = 36

I would take a brainliest
Answer:
perpendicular
Step-by-step explanation:
for an equation to be parallel, the equations would have to have the same slope. for and equation to be perpendicular, the slopes have to be reciprocal, like 5/1 and 1/5, or 2/15 and 15/2. Also, one slope has to be negative. These equations match the definition of perpendicular lines.
