Help me please. Very much appreciated​

Mathematics
1 answer:
olya-2409 [2.1K]3 years ago

Answer:

63mm

Step-by-step explanation:

7mm+8mm=15.

15×15=225

12×12=144(area equals base times height) add 225-144=81(here we are using the Pythagoras theory) so you search for the square root of 81 which is 9 meaning the height is 9. since we say area is 1/2base times height we should take 1/2 ×9×12=63.if the answer doesn't match with the answer in your book please tell me right away so that I can try another method thank you

belka [17]

Answer: C

Step-by-step explanation:

Since there are 12 inches in 1 foot,

42 feet converts to 42 x 12 = 504 inches. If he makes a cut starting on one side, he will make 504/20 = 25.2 cuts. Since he won't make a partial cut, the answer is 25

Using mixed numbers, write a problem in which an estimate is enough to solve the problem.​
KengaRu [80]

explain:

Estimating Differences of Fractions and Mixed Numbers

Estimating Differences of Fractions and Mixed NumbersRecall that estimation is a method for finding an approximate solution to a problem. Even when you are asked to find an exact ko, estimation is a useful way to get an idea of a reasonable solution to a problem. Once you have found an exact answer, you can check your answer against the estimate.

Analyze the diagram below and complete the instructions that follow.
dedylja [7]

The value of y is 11 if the measure of the angle (x + 6y) is 90 degree and x = 24 option first is correct.

<h3>What is a perpendicular line?</h3>

Lines that intersect at a right angle are named perpendicular lines. Lines that are always the same distance apart from each other known as parallel lines.

We have a perpendicular line shown in the picture.

The measure of the angle (4x - 6) is equal to 90 degree.

4x - 6 = 90

4x = 96

x = 24

Similarly, the measure of the angle (x + 6y) is equal to 90 degree:

x + 6y = 90

Plug x = 24

24 + 6y = 90

y = 11

Thus, the value of y is 11 if the measure of the angle (x + 6y) is 90 degree and x = 24 option first is correct.

Parallel lines are cut by a transversal such that the alternate interior angles have measures of 3x + 17 and x + 53 degrees. Th
vekshin1
It is a rule that alternate angles are equal, so using this fact, we can say that:
3x + 17 = x + 53
- x
2x + 17 = 53
- 17
2x = 36
÷ 2
x = 18
Which means that your answer would be B. x = 18
I hope this helps!
