Answer 1

Answer:

AB = 4.62 m∠A = 22° m∠B = 68°

Step-by-step explanation:

Tan A = 1.7/4.3 = .39534...

m∠A = arctan .39534... ≅ 22°

m∠B = 90 - 22 = 68°

AB = [tex]\sqrt{1.7^{2} + 4.3^{2} } = \sqrt{2.89 + 18.49} = \sqrt{21.38} = 4.62[/tex]

A+B=44
A : B is equvililent to 13 :8
Please solve

Answers

Step-by-step explanation:

13:8A=13x. B=8x13x + 8x = 44 21x=44 x=2.095

13:18 is in simplest form, so it’s multiplied by something, let’s call it x

So A + B equals 13x + 8x

13x + 8x = 44
21x = 44
x =44/21

Plug in to check:
13(44/21) + 8(44/21) = 44
572/21 + 352/21 = 44
924/21 = 44
44 = 44 :)

Answer:

a = 10

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is qual to the sum of the squares on the other 2 sides, that is

a² + 24² = 26²

a² + 576 = 676 ( subtract 576 from both sides )

a² = 100 ( take the square root of both sides )

a = [tex]\sqrt{100}[/tex] = 10

Answers

Answer and Step-by-step explanation:

A. Cruz is correct.

B. When we have a negative within a cube root, what we can do is move the negative sign from inside to outside the cube root.

[tex]\sqrt[3]{-64} = -\sqrt[3]{64}[/tex]

Now that we have a positive number within the cube root, we can solve the cube root itself.

So what is the cube root of 64?

The answer is 4, and since we have a negative sign outside of the cuberoot, we just put a negative sign, our answer is -4.

C. Aaron could've got it wrong because he did it a square root instead of a cuberoot of 64. Square root of 64 is 8, while cube root is 4.

Jacob could've gotten it wrong because he must've followed the fallacy that you cannot cube root a negative number.

6+n/5-6=9-6

(Now you will have to simplify.)

n/5=3

(You will have to multiply all terms by the same value to eliminate fraction denominators.)

n/5=3

(You will now have to simplify.)

n=15

8. 28.00111604 or 28

Step-by-step explanation:

30 +90 =120 180-120=60

Sin A = a/c, so a = cSin A. Also Cos A = b/c, so b = cCos A so Sin30=14/c=28

Cos30=b/28 b=24.25

now 14^2+24.25^2=c^2 which gives 28.00111604 or 28

Pls help! I don’t understand!! :/

Answers

Answer:

p=1/5t

Step-by-step explanation:

Since t is 100% of the items sold and p is 20% of that, the profit, p is 20% of t, or 1/5t.

Answer:

p = t(0.2)

Step-by-step explanation:

The profit is 20% of the total price. So if you multiply the total price by 0.2, you will get 20% of the total price which is the profit.

A recipe for sparkling grape jucie calle for 1 1/2 quarts of sparkling water and 3/4 quart of grape jucie. How much sparkling water would you need to mix with 9 quarts of grape jucie?

Answers

Answer: 18 quarts of sparkling water

Step-by-step explanation:

From the question, we are informed that a recipe for sparkling grape jucie calle for 1 1/2 quarts of sparkling water and 3/4 quart of grape jucie.

When there's an increase in the quarts of grape juice to 9, it simply means that the former grape juice has been multiplied 12 times (9 ÷ 3/4 = 9 × 4/3 = 12).

Therefore, we would also multiplybl the sparkling water given by 12 to get the new quantity needed. This will be:

= 1 1/2 × 12

= 3/2 × 12

= 18 quarts of sparkling water

16 ÷ 22 + (6 x 2) - 8

Answers

I did the PEMDAS method (P= parentheses, E= exponents, M= multiplication, D = Division, A= addition, S = subtraction.)

First I did what’s inside the parentheses, (6x2) and got 12.

Then I divided 16 by 22 and received 0.72.

I added 0.72 with 12 and the result was 12.72.

Last step was to subtract 12.72 - 8 and that equals 4.72

16 ÷ 22 + (6 x 2) - 8 = 4.72
