Answer:
The answer is 23 because they have to add up to 90-kai :)
Step-by-step explanation:
So, ∠a + ∠b = 90°
67° + ∠b = 90°
∠b = 90° - 67°
∠b = 23°
Answer:
The measure of ∠b is 23°.
Step-by-step explanation:
Complementary angles are angles that add together to always be 90°. The problem gives us this information at the start:
∠a + ∠b = 90°
∠a = 67°
You can apply this information to the equation by getting the problem of:
67° + ∠b = 90°
To solve this equation you simply rearrange the terms, and subtract 67 from 90:
90° - 67° = ∠b
After rearranging the terms and subtracting 67 from 90 you are left with the following result:
∠b = 23°

Lucy was watching her brother's team play baseball in the town playoffs. A man selling raffle tickets posed a challenging question to the crowd. He asked if anyone could figure out the area of the shaded half of the baseball field. Help Lucy figure out the answer by using the drawing below. please explain how you got your answer!
Answers
Step-by-step explanation:
Area is Base x Height right?
so, the base of the triangle would be 90 ft and the height would be 90 ft!
So 90 x 90 = 8,100 ft!!
This is how I think, so it may be wrong, but this is how I do it!
answer:
a=1/2×b×h
a=1/2x90×90
a=45×90
a=4,050 ft.
in simpler terms....
90×90=8100
this is the area of the ENTIRE FIELD so to find half divide by two 8100÷2=4,050.
4,050 ft.

Irene wants to use equivalent ratios to solve 3,712÷64, but she can't remember how. Show Irene what to do.
Answers
Answer:3,712÷64=58
Step-by-step explanation:
Answer: The ratio is 58:1, and the division is = 58. Scroll for solving, check, and notes.
Explanation:What we know:
The question wants us to use equivalent ratiosThe numbers 3,712 and 64 have common denominatorsAn equivalent ratio is a ratio that is something of a simplified form of large numbers, written in a fraction, with a colon, or with the word 'to'How to solve:
We need to find the equivalent ratio of 3,712 and 64, and then solve the question based on that.
Process:Finding equivalent ratios
Set up equation 3712/64
Rewrite into colon-ratio form 3712:64
Divide by common denominator /64 /64*
Solution: =58:1
*Read bottom of notes to find out how I found this denominator
Answer: The ratio is 58:1; the solution to the division is 58.Notes:
There is no way to always know the ratio's common denominator. However, there are some general rules of thumb that may help:
-All numbers have a common denominator of 1. Sometimes, that's the most simplified form.
-All even numbers (Those that end in {0, 2, 4, 6, or 8}) have a common denominator of 2
-All numbers whose digits add up to {3, 6, or 9} (such as 12: 1+2 = 3) have a common denominator of 3.
-These three numbers serve as basic building blocks. You can keep simplifying with them until you get to a prime number. Let's use our problem as an example:
3712 and 64 - both are even, simplify by 2
1856 and 32 - both are even, simplify by 2
928 and 16 - both are even, simplify by 2
464 and 8 - both are even, simplify by 2
232 and 4 - both are even, simplify by 2
116 and 2 - both are even, simplify by 2
58 and 1 - there is a prime number, so this is the simplest form.
Now we take all of our simplifications: 2^6. 2^6 = 64, so the common denominator is 64.
Check:
Our ratio, 58:1, is the simplified form of 3,712 div. 64. This is seen better by rewriting both into a fraction-ratio form:
58:1 3712 div. 64
58/1 3712/64
Luckily, our ratio has a 1 in it. This means that when we multiply the ratio by 64 (what the 1 represents), it should yield the original equation.
3712/64 = 58/1
3712/64 = (58/1)*64
3712/64 = 3712/64
Therefore, 58:1 is the correct ratio.
Use the number line to answer the question.
Answers
Answer:
2.23
Step-by-step explanation:
The reason why this is your answer is that this number is between 2 2/10 and 2 3/10. That means that turned into decimals, this number will be somewhere between 2.2-2.3
Now, we can see that this is 3 units away from 2 2/10 on the number line, which tells us that the decimal is 2.23
So hence, your answer is 2.23

Answer:Multiplication and division both need to have a common denominator or else you would get an incorrect answer. Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators."
Hii
Yes! They are indeed related. When dividing fractions, we need multiplication. Say, for example. We need to multiply the reciprocal of the second fraction to the first. So. If we needed to answer a question like "2/4 divided by 1/2" We would need to find a common denominator. We find common denominators by multiplication. We can do this 2 ways. See below.
For one, we could multiply 2 and 4 to get 8.For two, we could see what 2 and 4 both multiply by. In this case 8.
Then we would need to divide 2 and 1.
1 can go into 2 twice. 1+1 is 2.Then we multipy to find our denominator (this is a example of using multiplication with divison). 2x4 is 8. So the fraction would be 2/8.Simplify.
Find the GCD (or HCF) of numerator and denominator GCD of 2 and 8 is 2Divide both the numerator and denominator by the GCD 2 ÷ 2 / 8 ÷ 2Reduced fraction: 1 / 4 Therefore, 2/8 simplified to lowest terms is 1/4.
Simplified you'd get 1/4.
(tip, once the numerator hits 1, you can no longer simplify)

Answers
Answer:
I think the answer will be 32,768 cubic units..
Step-by-step explanation:
The volume formula is length times width times height and you say that the area of the shaded face is 96 square cm is better we divide
96/3 =32
So, we took the colume formula like this:
V= L x W x H
= 32 x 32 x 32
= 1,024 x 32
= 32,768 cubic units

Answers
Answer:
c
Step-by-step explanation:
The surface area of the square pyramid is 1040 ft² in the given figure.
What is the total surface area of the pyramid?The total surface area of the given pyramid can be expressed as:
Surface area of a square pyramid = A + (1/2) p × s
where A is the base area, p is the perimeter of the base, and s is the slant height
As per the question, we have
length (l) = 20 ft
base perimeter (p) = 4l = 4 × 20 = 80 ft
base area (A) = l² = 20² = 400 ft²
slant height (s) = 16 ft
Substitute the values in the formula for surface area:
Surface area = 400 + 1/2 × 80 × 16
Surface area = 400 + 1280/2
Surface area = 400 + 640
Surface area = 1040 ft²
Thus, the surface area of the square pyramid is 1040 ft².
