eronica wants to cut a sheet of paper into squares with an area of 12 square inches. For the best approximation, the length of each side of the square pieces of paper must be approximately equal to - inches. If each side were exactly this length, the area of each square would be - square inches.
The side length must be 3.454 inches, so the exact area is 11.999 inches.
What side length the squares must have?For a square of side length S, the area is given by:
A = S^2.
In this case, we know that the squares have an area of 12 square inches, replacing that in the area equation we get:
12 in^2 = S^2
If we apply the square root on both sides, we get:
√(12 in^2) = √S^2
3.464 in = S
This is an approximation to the side length, if each side measured this, the exact area would be:
A = (3.464 in)^2 = 11.999 in^2
Which is almost what we wanted to get.

Find the measure of ∠6.
Answer:
m<6=77°
Step-by-step explanation:
Because the angles marked 3x+5 and 4x+7 are same side exterior angles, they are supplementary, meaning that
3x+5°+4x+7°=180°
7x+12°=180°
7x=168°
x=24°
Because the angles marked 6 and 3x+5 are corresponding angles, they are congruent, so:
<6=24*3+5
<6=77°

Answer:
A= 145.12mm^2
Step-by-step explanation:
The diagram shows us a Right angle triangle; so, I use Phythagoras' Theorem, to find length of the base.
c^2 - b^2 = a^2
27^2-12^2 =a^2
585. = a^2
Square root both sides
a = root 585
= 24.18677324
A= bxh/2
= root 585 x 12/2
= 18 root 65
= 145.1206395
A= 145.12mm^2 to 2.d.p
(Haven't rounded up in calculations until the end. Thus, using the exact values of root 585,for example. )

Answer: x = 20
Step-by-step explanation:
We know that the sum of the angles in a triangle is 180 degrees.
Therefore, we can set up an equation:
46 + 71 + 4x - 17 = 180
We can combine like terms:
4x +100 = 180
Subtract 100 from both sides:
4x = 80
Divide both sides by 4:
x = 20

The solid below is made from cubes.
Find its volume.
Answer:
48 cm^3 is the answer.
Answer:
the volume is 48 cm^3
Step-by-step explanation:
if one cube is equal to 1 cm, and the width is 2 cubes, height is 4 cubes, and length is 6 cubes, then you have to convert each measurement to cm. Now we have each measurement:
height = 4 cm
width = 2 cm
length = 6 cm
Next, you have to multiply 2 by 4 (or 2 by 6, it wont matter what order you multiply), which is 8. After that, you have to multiply 8 by 6, which is 48.
Hence, the volume is 48 cm cubed, or cm^3.

Step-by-step explanation:
You roll a number cube twice. What is the probability of rolling a 5 first and then rolling an even number? 1/4, 1/3, 1/12, 1/36?
Answer:
A = event of rolling a 2 on the first roll
P(A) = 1/6 because there is only one "2" out of six labels total on the number cube.
B = event of rolling an odd number on the second roll
P(B) = 3/6 = 1/2 since there are three odd numbers {1,3,5} out of six total
The events A and B are independent, so we can multiply the probabilities
P(A and B) = probability of both events happening simultaenously
P(A and B) = P(A)*P(B)
P(A and B) = (1/6)*(1/2)
P(A and B) = (1*1)/(6*2)
P(A and B) = 1/12
Final Answer: 1/12
Note: The fraction 1/12 is approximately equal to 0.0833

D. 972.001 = 9 x 100 +7 x 10+ 2 + 1/10
Answer:
C is correct, D might be correct if you forgot 000 at the end of the question.
Step-by-step explanation:
005 = 5x1 so A is incorrect
945 = 9x100 + 4x10 + 5x1 so B is incorrect
15.859 = 1x10 + 5x1 + 8/10 + 5/100 + 9/1000 + so C is correct
973.001 = 9x100 + 7x10 + 2x1 + 1/1000 so D is incorrect

Write an equation to represent the following situation:
Adult tickets for a movie cost $12 and tickets for a child cost $8. If the theater collected $600 for the 10PM show, how many of each ticket did they sell?
How many children's tickets were sold if 26 adult tickets were sold?
What do the intercepts represent ?
Answer:
A. 36 children tickets
B. The intercepts of this equation represent how many tickets one type of ticket would have sold if the other type of ticket was not bought at all.
Step-by-step explanation:
So lets start with what we know
Adult tickets = $12
Children Ticket = $8
The theater collected $600.
So with this information, we can write down the equation
12x + 8y = 600
Note: x is the variable for the number of adult tickets and y is the variable for the number of children tickets
Find the amount of children tickets sold if 26 adult tickets were sold
So, this problem is trying to make us solve for y, if x = 26. Let's plug in the values and start solving for that value!
Solve for y if x = 26
12x + 8y = 600
12(26) + 8y = 600
312 + 8y = 600
-312 -312
8y = 288
8y / 8 = 288 / 8
y = 36
So, we have our answer as y = 36.
Solution Statement:
If 26 adult tickets are sold, 36 children tickets must be sold if the total amount collected was $600.
The intercepts of this equation represent how many tickets one type of ticket would have sold if the other type of ticket was not bought at all.
If you have any questions, please let me know in the comments section of this answer! If you could mark this answer as the brainliest, I would greatly appreciate it! :D
