Answer:
Step-by-step explanation:
Surface area of a cube = 6a²
When each dimension is doubled, Side =2a
Surface area = 6*(2a)² = 6 * 4*a² = 4*(6a²)
So, when each dimension is doubled, surface area is 4 times of the original surface.
a = 3a
Surface area = 6*(3a)² = 6 * 9 *a² = 9 *6a²
= 9 times the original area
a = 4a
Surface area = 6*(4a)² = 6* 16 * a²
= 16 * (6a²)
= 16 times of original area
what is the diameter of a circle with area of 113.04 square cm. use 3.14?
pls fast
Answer:
diameter of a circle = 12cm
Step-by-step explanation:
Area of a circle = πr²
113.04 cm² = πr²
First, search for radius (r) :-
r = √(113.04/π)
r = 6 cm
As diameter is equals to 2×radius
The diameter of a circle = 2 × 6cm
Final answer = 12 cm
Answer:
d≈12cm
Step-by-step explanation:
Using the formulas
A=πr2
d=2r
Solving for d
d=2A
π=2·113.04
π≈11.99696cm

Write the equation of the line in slope-intercept form using y=mx+b
Answer:
y = 3/1x + 5
Step-by-step explanation:
The line crosses the y-axis at 5, meaning the y intercept is 5.
The slope has a rise of 3 and run of 1, making the slope 3/1.

Answer:
Kari has 14.28% of each week for research on the decline in the bee population.
Step-by-step explanation:
Given that Kari has one day each week to research the decline in the population of bees, and knowing that each week has seven days of duration, to determine what percent of each week she has for research on this topic, the following calculation must be performed:
7 = 100
1 = X
(1 x 100) / 7 = X
100/7 = X
14.28 = X
Thus, Kari has 14.28% of each week for research on the decline in the bee population.

Find the surface area of the triangular prism.
Answer:
First picture: 60
Second picture:
Step-by-step explanation:
The first step for the first picture is to find the area of the triangle on top. In order to do that, we have to use the equation: (W*L*1/2)
(3*4*1/2)=6
Then, we multiply the above equation by the Height. Which makes the equation become 60.
The first step for the second picture is the same. We first find the area of the triangle on top.
(12*9*1/2)=54
Then we multiply the height by our above answer.
(54*20)=1,080
The other measurements that were there aren't needed. So, next time, completely ignore them!
Hope you have a good day/night! Good luck!
In the figure given below, calculate x and y.
Answer:
x = 73°
y = 39°
Step-by-step explanation:
x + 107 = 180 {Linear pair}
x = 180 - 107 {Subtract 107 from both sides}
x = 73°
y + 51 + 90 = 180 {straight line angles}
y + 141 = 180
y = 180 - 141
y = 39°
Why does a plant only need to use a portion of its energy and not the entire thing?
Answer:
Because All organisms, including humans, need energy to fuel the metabolic reactions of growth, development, and reproduction. But plants can't use light energy directly for their metabolic needs. And half of there energy is light energy so it must first be converted into chemical energy through the process of photosynthesis.

Answer:
Step-by-step explanation:
Number of red marbles=4
Number of blue marbles=3
P(B)=3/10
P(R)=4/10=2/5
Total number of marbles=10
Answer:
The number of red marbles is 4. The number of blue marbles is 3. The total number of marbles is 10 because 4+3+3 is 10. P(red) is 2/5 because there are 10 total marbles and there are 4 marbles which is equal to 4/10 marbles are red, and you simplify 4/10 to 2/5. P(blue) is 3/10 because there are 3 blue marbles out of 10 marbles.
A trapezoid has a height of 8 cm and bases with lengths of 14 cm and 8 cm. Tina says the area of the trapezoid is 176 cm2.
Find her error, and correct the error.
Tina did not multiply by _ . The correct area is _ cm2.
Answer:
Step-by-step explanation:
Let's do this properly:
Area of trapezoid = average length times height.
Here,
Area = (1/2)(8 cm + 14 cm)(8 cm), or
= (11 cm)(8 cm) = 88 cm^2
It appears that Tina forgot to divide the sum of 14 cm and 8 cm by 2. Thus, her answer is twice as large as it should be.

A train left William's town at 7:35 P.M. The train traveled for 1 hour and 30 minutes to Richmond. Then it traveled 3 hours and 55 minutes to Kingwood. What time did the train arrive in Kingwood? HELP!! :(
Answer:
12:55 A.M
Step-by-step explanation:
1 hour and 30 minutes plus 3 hours and 55 minutes equals 5 hours and 25 minutes.
The train left at 7:35 P.M. Now that we have all of the necessary info, we put it together.
12:55 A.M.
Using time rules and whatever, we add the 5 hours and 25 minutes to 7:35. Which gives us the answer right above, 12:55 A.M. is the time that they will arrive at Kingwood.
