Answer:
406
Step-by-step explanation:
A rectangular prism has six sides, three pairs of matching ones
Start by finding the area of each of the three kinds of sides
14 x 5 = 70
5 x 7 = 35
7 x 14 = 98
Now multiply each of these answers by two, for the number of sides that have each surface area
140
70
196
Finally, add all of the areas together to find the surface area of the whole shape.
140 + 70 + 196 = 406

Answers
Answer:
1 1/27 = 28/27
Step-by-step explanation:
First you evaluate your parenthesis, and to do that you need to find the Least Common Denominator of 2/3 and 2/9. The least common denominator would be 9. 3 x 3 = 9 so you multiply 2 x 3 = 6. 6/9 - 2/9 = 4/9. 7/3 x 4/9
7 x 4 = 28
3 x 9 = 27
28/27 = 1 1/27
Hey there!
7/3 * (2/3 - 2/9)
= 7/3 * 4/9
= 7(4) / 3(9)
= 28 / 27
≈ 1 1/27
Therefore, the answer should be:
28 / 27
OR
1 1/27
Either should work because they are both equivalent to each other.
Good luck on your assignment & enjoy your day!

Which model represents the product 3×25? (Giving brainliest.)
Answers
I think that is the answer because it says 2/5 where two rows are shaded and three more rows remain unshaded so, when you add that three and two it's altogether 5, so I think that is the answer, please check out the document I have uploaded.
Answer:
the one you are currently clicking on (you're correct :) )
Step-by-step explanation:
For the item you are currently clicking on, there are three columns--each with five rectangular sections. Each of the three columns--as we can see on the label to the left, is equal to 1. So, the five split pieces must all combine to stack up to 1. This means that 1 must be divided amongst 5 pieces, so we divide 1 by 5: 1/5.
You are trying to find the model that represents 2/5 (times 3, so it will have three rows). For the model you are clicking on, each column is showing two rectangles being there. This means that you have two sections of 1/th--or, 2/5ths present.
This means that you have the fraction of 2/5th, and you have it three times, so it represents three 2/5ths fractions, or 3 x 2/5.
(Remember, multiplication is repeated addition. So, 3 times of something means that its there 3 times, you have three 2/5ths)
PLEASE HELP SOON! Please answer the question and explain step by step how you got your answer. Julian is using a biking app that compares his position to a simulated biker traveling Julian's target speed. When Julian is behind the simulated biker, he has a negative position. Julian sets the simulated biker to a speed of 20 km/h. After he rides his bike for 15 minutes, Julian's app reports a position of -2 1/4 km.
What has Julian's average speed been so far?
Answers
Answer:
11 km/h
Step-by-step explanation:
What I did is found out how fast the simulated biker traveled for 15 minutes, by doing
[tex]\frac{20}{4}[/tex] = 5
Since 15 minutes is 1/4 of an hour. Or you could do 20/60 = 1/3, 1/3 being how much the biker traveled in a minute and multiply that by 15
15×[tex]\frac{1}{3}[/tex] = 5
Now we know that the biker traveled 5 km, now subtract 5 by [tex]2 \frac {1}{4}[/tex]
5 - [tex]2 \frac {1}{4}[/tex] = [tex]2 \frac {3}{4}[/tex]
Julian traveled [tex]2 \frac {3}{4}[/tex] in 15 minutes, now to find his average speed you multiply [tex]2 \frac {3}{4}[/tex] by 4 since [tex]2 \frac {3}{4}[/tex] is the distance traveled in 1/4 an hour.
[tex]2 \frac {3}{4}[/tex] × 4 = 11
11 km/h

Please explain its due tonight and I need to study for my math unit test tomorrow if I fail I don’t pass.
Answers
Once u distribute you should have
-3n-15=12
Now you want to add 15 to both sides to cancel it out ( because n has to be isolated)
-3n=27
Now you want to divide by -3 to both sides to get n by itself
n=-9
-3•n -3•5
-3n-15 = 12
-3n+15 = 12+15
-3n = 27
-3n/-3 = 27/-3
n = -9 or -9n
CIRCLE THEOREM QUESTION ------> PLEASE HELP WITH THIS!
I REALLY NEED YOUR HELP!
Answers
Answer:
e = 126
Step-by-step explanation:
Both triangles are isosceles triangles. Therefore in the smaller triangle, there are two angles that are equal to 42 degrees (the other one is next to e)
42 + 42 = 84
there are 180 degrees in a triangle
180 - 84 = 96
So the last angle in the triangle (The little one) is equal to 96 degrees.
The rule for cyclic quadrilaterals is that the two opposite angles equal 180. So the angle opposite 96 degrees will be equal to:
180 - 96 = 84
As the larger triangle is also an isosceles (as mentioned above), two angles will be equal to each other. The two angles that are equal are at the bottom left. As one of them is equal to 84, the other is also equal to 84. This means the last angle (the one at the top) is equal to:
180 - (84 + 84) =
180 - 168 = 12
Angles on a straight line always equal 180 degrees. So 'e' is equal to 180 minus the other two triangle angles on the line they all share.
180 - (12 + 42) =
180 - 54 = 126
Therefore e = 126

[tex]144 in^{2}[/tex]
Step-by-step explanation:
We can see in the figure that you have 4 triangles, all congruent, and 1 square in the middle. The measure of the square is 8x8, so first find the area of that, 64. Then, we only need to find the area of 1 triangle and multiply that by 4, as you have 4 triangles in the figure. The area of a triangle is (base×height)/2 so fill in the values. The base is 8 in, and the height is 5 in. 5×8 is 40, so we divide that by 2 and get 20. Then multiply this by 4, and you get 80. Now, take your original area of the square, and add it to the area of the 4 triangles. 64+80=144
