Answer:

#43: D

#44: 11

Step-by-step explanation:

#43-

1. 2x + 4 =K= 2x+22

place function together

2. combine like terms

2x+4=k=2x+22

-2x -2x

4=K= 22

-4 -4

3. gives you the answer

which is K = 18

#44 f(x) = 2/3x + 3 .....f(12)

1. place 12 un the equation

f(12) = 2/3 × 12 +3

2. f(12) = 8+3

3. f(12)= 11

This is the best I can do

Doug lives 7. Block away from his school . Each block is about 265 feet long. What is total round-trip dostance,in miles that Do

olga_2 [115]

Answer:

B : 0.7

Step-by-step explanation:

Given:

Doug lives 7. Block away from his school.

Each block is about 265 feet long.

Question asked:

What is total round-trip distance,in miles that Doug walks to and from school each day ?

Solution:

Each block is about = 265 feet

7 Block = $265\times7 = 1855 \ feet$

As he lives 7 block away from his school that means his round trip distance is,

7 block ( travel during going to school ) + 7 block ( when return from school )

<em>Therefore, his total round trip is 14 block, means 1855 feet + 1855 feet = 3710 feet.</em>

Now, we have to convert it into miles as here asked: (unitary method)

5280 feet = 1 mile

1 feet = $\frac{1}{5280}$

3710 feet = $\frac{1}{5280}\times3710$

= $\frac{3710}{5280} = 0.7 \ miles$

Thus, total round-trip distance,in miles that Doug walks to and from school each day is 0.7 miles.

Ms santos seashells into 4 row she puts 6 seashells in each row how many seachells are there altogether

kati45 [8]

4 rows and 6 seashells in each row.
Row 1: 0 0 0 0 0 0
Row 2: 0 0 0 0 0 0
Row 3: 0 0 0 0 0 0
Row 4: 0 0 0 0 0 0

You add all of them together 6+6+6+6=24
Or you could do 6x4 and your answer would be 24
So the answer to the question is 24 seashells.

3. Janet is flying a kite on a string that is 75m long. The kite is 62m above the ground. Estimate the distance between Janet an

konstantin123 [22]

Answer: a) It will be a right triangle with a hypotenuse of 75 and a vertical leg that is 62.
b) The length of the kite string is 75 (given in the problem). However, I believe you are looking for the distance from the spot on the ground beneath the kite to Janet. That is about 42.2 m.

To find the missing distance in the right triangle. You have to use the Pythagorean Theorem. I set it up and solve it below.

a^2 + b^2 = c^2
x^2 + 62^2 = 75^2
x^2 + 3844 = 5625
x^2 = 1781
x = 42.2 (about)
