I’m wondering if somebody can help me with this-

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°

The answer is D

Answer:

4 percent

Step-by-step explanation:

Answer:

25/100 or 1/4 or 25%

Step-by-step explanation:

Add all the number of bands given which sum up to 100 and then divided 25 by it.

Answer:We have, 38% × x = 190

or,

38

100

× x = 190

Multiplying both sides by 100 and dividing both sides by 38,

we have x = 190 ×

100

38

x = 500

If you are using a calculator, simply enter 190×100÷38, which will give you the answer.

Step-by-step explanation.

Amelia is correct because she has the heviest bag

The volume of the prism shaped fish tank is: 408 in.³.

Volume of prism = base area × height of prism.

The fish tank is a prism having a height of 8 inches. To find its volume, find the base area, which is the area of the composite figrue given.

Thus:

Base area = area of rectangle + area of triangle = (length × width) + (1/2(base × height).

Given:

Therefore:

Base area = (7 × 6) + 1/2(3 × 6)

Base area = 51 in.²

Volume of the prism shaped fish tank = 51 × 8 = 408 in.³.

Answer:

i think he is missing a pair of red socks

Step-by-step explanation:

Answer:

160

Step-by-step explanation:

he read 40 pages on the first day. he read 1/4 of the remaining pages, and still had 1/2 of the book to read. this means that 40 is about 1/4 and to find the total amount of pages, you have to multiply 40 by 4.

40 x 4 = 160

hope this helps :)

Answer:

70 pages. (If by 1 4 and 1 2, you mean fractions.)

Step-by-step explanation:

1/4 of 40 is 10. This is calculated by dividing 40 by 4, since the denominator in 1/4 is 4.

1/2 of 40 is 20. This is calculated by dividing 40 by 2, since the denominator in 1/2 is 2.

Add that together and that's 70.

Answer:

-3.35 is your answer. B.

Answer:

With the way the problem is facing, the correct option is B.

[tex]6.2[/tex] ≈ [tex]6[/tex]

[tex]9.55[/tex] ≈ [tex]10[/tex]

[tex]6 - 10 = -4[/tex] because of the order. Otherwise, it would be positive 4

[tex]6.2 - 9.55 = -3.35[/tex]

Answer:

12) just plug in the numbers to the equation

C = (-4,5)   D = (-2,3)

11) 8.426

10) 3, 4, 5

level 3-4) 24

Step-by-step explanation:

11) 7^2 + 11^2 = c^2

   49 + 22 = c^2

    √71 = √c^2

    c = 8.426

10) 3, 4, 5 is a special right triangle but

3^2 + 4^2 = 5^2

25 = 25

level 3-4)

7^2 + h^2 = 25^2

49 + h^2 = 625

√h^2 = √576

h = 24

Answer:

Step-by-step explanation:

so he made a total of 70 bowling attempts, and 14 out of those 70 he actually knocked all of the pins down, so what its asking, is what is 14 precent of 70 because the wording is "out of" which means its a part of the entire 70. so you now know what its asking, how do you solve it? well, you would divide 14 by 70 to get the answer in decimal form: 14 / 70 = 0.2000 Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage: 0.2000 * 100 = 20.00%
