Answer:

The problem of <u>(Choice B)</u> could be solved with the expression (4+2)\times4.

Step-by-step explanation:

Given:

Which problem could be solved with the expression (4+2)\times4?

(Choice A) A Bobby sold 4 baseball cards on Monday. He then sold 2 more on Tuesday. He sold the same amount for 2 weeks. How many did he sell?

(Choice B) B Danny ran 4 miles in the morning and 2 miles in the afternoon. He did this for 4 days. How many miles did he run?

(Choice C) C Suzanne makes wooden dolls. She made 2 in the morning and 2 in the afternoon. She did this for 4 days. How many dolls did she make?

Now, to choose one answer:

The problem of (Choice B) could be solved with the expression (4+2)\times4.

(Choice B) Danny ran 4 miles in the morning and 2 miles in the afternoon. He did this for 4 days. How many miles did he run?

<em>Danny ran 4 miles in the morning and 2 miles in the afternoon.</em>

<em>So, adding both the miles we get:</em>

<em />4+2<em />

<em>Now, he did this for 4 days.</em>

<em>Thus, multiplying by 4 we get:</em>

(4+2)\times 4

As, the other choices doesn't match the expression.

Therefore, the problem of (Choice B) could be solved with the expression (4+2)\times4.

Find the Length of AC. Round answers to the nearest hundredth (2 decimal places)
lara31 [8.8K]

Answer:

32.78

Step-by-step explanation:

Assuming that we have two right triangles joined together, with one having adjacent side a, with a side of 12 ft opposite reference angle 30°, and the other one having adjacent side b, with a side of 12 ft opposite reference angle 45°. Thus, a + b = length of AC.

Let's find a and b.

Finding a:

Reference angle = 30°

Opp = 12 ft

Adj = a

Using trigonometric ratio formula, we have:

tan(30) = 12/a

Multiply both sides by a

a*tan(30) = 12

Divide both sides by tan(30)

a = 12/tan(30)

a = 20.78 (nearest hundredth)

Finding b:

Reference angle = 45°

Opp = 12 ft

Adj = b

Using trigonometric ratio formula, we have:

tan(45) = 12/b

Multiply both sides by a

b*tan(45) = 12

Divide both sides by tan(45)

b = 12/tan(45)

a = 12

Length of AC = 20.78 + 12 = 32.78

Solve -1/8y ≤ 34. then graph the solution.
motikmotik

Answer:

Multiply each term in −1/8y≤34 by −8. When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.

−1/8y x −8 ≥ 34 x −8 Simplify −1/8y x −8

y ≥ 34 x −8

Multiply 34 by −8.

y≥−272

-BARSIC- [3]

Answer:

Step-by-step explanation:

hello :

put x = -5 in this equation : a(4-x) =-3x + b

a(4+5) =15 + b

9a = 15 +b

b = 9a - 15

the values of a and b is all order  pair :   ( a  ; 9a-15)  a real number
