Answer:
The 1st choice
Step-by-step explanation:
(a) the first and second ones are the only triangles with all three acute angles. The 2nd one has more than 1 line of symmetry so the 1st must be the answer.
(b) This one really depends on which side of the triangle is each length. One way to do it is A squared + B squared = C squared. 8 equals c because it is the largest side and 7.5 is A. This would be put out like 56.25 + B = 64. Subtract 56.25 from both sides to get B = 7.75.
OR, if 8 is not the longest side 7.5 squared + 8 squared = C squared which would be 120.25 = C squared. So, you would find the square root of 120.25 which is 10.97.

For the data set summarized in the boxplot, identify the interquartile range (IQR). A) 22 B) 32 C) 57 D) 75
Answers
Answer:
IQR = 22
Step-by-step explanation:
The interquartile range, or the IQR, is quartile 3 - quartile 1. The box in the middle contains quartile 1, median, and quartile 3. The median is the line inside the box, quartile 1 is the line to the left of the median, and quartile 3 is the line to the right of the median. In this case, the IQR is 70 - 48.
IQR = 22

The interquartile range of the data set summarized by the box plot is 22.
What is the interquartile range?
On the box in a box plot, the first line to the left represents the lower (first) quartile. 25% of the score represents the lower quartile. The third line on the box represents the upper (third) quartile.
Interquartile range = Q3 - Q1

Answers
Answer:
102º
Step-by-step explanation:
So you know that ABC is an Isosceles triangle as AB=AC therefore, angle ABC is equal to angle ACB.
You also know that even though it doesn't look like it, ABP is an equilateral triangle as AB, AP and BP are equal so all those angles must equal 60º.
So:
ABC = 60 - 21 = 39º
and since ABC= ACB
ACB also equals 39º.
Because angles in a triangle add to 180º, BAC is consequently:
180- (39+39) = 180 - 78 = 102º
BAC = 102º

The tires on a compact car are 18 inches in diameter.
a. How far does the car travel after the tires turn once? Use 3.14 as pi
b. How far does the car travel after 12 rotations of the tires? Use 3.14 as pi.
Answers
Answer:
1. 56.52 inches
2. 141,300 inches
Step-by-step explanation:
One turn of the tire is the circumference. Therefore, we have to find the circumference first. C = πd = 18π = 18 × 3.14 = 56.52 in
2500 rotations would be 2500 ⋅ 56.52 in = 141,300 in

Answers
Answer:
|x - 5| = 2
Step-by-step explanation:
Since we are not given a zero on the number line, we do the following:
Average = midpoint between two numbers on the number line
For this number line,
Average = 3 + 7 ÷ 2
Average = 5
Next we find how many units away are each number from the middle:
3 is 2 units away from 5
7 is 2 units away from 5
Units away = 2
Let's use the formula:
|x - average| = Units away
Substitute values into equation
|x - 5| = 2
Now we solve
Solve for x over the integers:
|x - 5| = 2
Split the equation into two possible equations:
x - 5 = 2 or x - 5 = -2
Add 5 to both sides:
x = -5 + 5 = 2 + 5 or x - 5 + 5 = -2 + 5
Answer:
x = 7 or x = 3

Answers
Answer:
Step-by-step explanation:
Answer:
A = picture attached
B = 51 in²
Step-by-step explanation:
I answered your other question, and I'm feeling lazy, so let me just copy + paste my answer here.
The picture attached is the answer for part A. You use the dimensions you already know from the first picture to fill in the net of the slice of pie.
Area of the triangle = 1/2 (base × height)
A = 1/2 (4 × 6) = 1/2 (24) = 12
The area of the triangle is 12. The top is a triangle, but the bottom is also a triangle with the same area. Therefore, the area of the two triangles combined is 24 in². Next, we have to find the area of the rectangle at the sides of the pie.
Area of rectangle = length × width
A = 5 × 2.5 = 12.
Since there are two rectangles with the same area on both sides of the pie, we can double it and get 25 in². We still have one rectangle left, the one at the back of the pie
A = 6 × 2.5 = 15
Add the areas altogether to get the answer.
24 + 12.5 + 15 = 51.5 in²
I hope this helps. Sorry if Part B's answer is wrong.

Answer ASAP! and whoever gets it right can have brainliest
Answers
Answer: 9
Step-by-step explanation:
the formula for the area of a triangle is a=bh/2, since the area is 54 we would need to multiply it by 2 which would be 108 to reverse the division. then we would divide it by 12 which would be 9 to reverse the multiplication.
Answer:
[tex]beinggreat78~here.[/tex]
The base is 9
Multiply 9 by 12, which is 108, and divide by 12, which is a way of giving you 9.
