4/3v =12

Simplify your answer as much as possible.

Answers

$\frac { 4 }{ 3 } v=12\n \n \frac { 3 }{ 4 } \cdot \frac { 4 }{ 3 } v=\frac { 3 }{ 4 } \cdot 12\n \n v=\frac { 36 }{ 4 } \n \n v=9$

4/3v = 12
3/4 × 4/3v = 12 × 3/4
v = 9

Four more than the product of 23 and Gregs height. Use the variable g to represent Gregs height

Answers

four more than (4+) the product of 23 and gregs height (23 times greg's height)
greg's height will be represented by g
4+23g

23g means 23 times g same as 23(g)

Final answer:

The expression that represents four more than the product of 23 and Greg's height is 23g + 4. Simplifying the expression gives us 5.385g.

Explanation:

The question is asking for an expression that represents four more than the product of 23 and Greg's height. We can represent Greg's height with the variable g. So the expression would be 23g + 4. If we simplify the expression, we get 5.385g.

If f(x) = 6 – 5x and g(x) = 4x – 1, evaluate f(x) – g(x) for x = –2. A. –11 B. 7 C. 9 D. 25

Answers

Answer:

D. 25

Step-by-step explanation:

f(x) = 6 – 5x and g(x) = 4x – 1

We want to subtract.

f(x) -g(x)= 6 – 5x -( 4x – 1)

Distribute the minus sign

6 – 5x - 4x + 1

I line them up vertically

– 5x +6

- 4x + 1

-------------------

-9x +7

Now let x = -2

-9(-2) +7

18+7

One hour after a hiker left camp, a biker set out to catch up. If the hiker traveled 3 miles per hour and the biker traveled 6 miles per hour faster, how long will it take for the biker to catch up with the hiker?

Answers

Answer:

30 minutes after biker left

Step-by-step explanation:

Given that :

Speed of hiker = 3 mph

Speed of biker = (3 +6) = 9 mph

Present Distance of hiker when the biker set out ;

Present Distance of hiker = speed * time = (3 * 1) = 3 miles

Time taken to catchup equals :

Present distance + (distance when biker set out) = bikers distance

Let time taken = x

(3 + (3 * x)) = (9 *x)

(3 + 3x) = 9x

3 + 3x = 9x

3 = 9x - 3x

3 = 6x

x = 3/6

x = 1/2 hours

x = 30 minutes

PLEASE PLEASE HELP IM BEING TIMED The two-way table represents data from a survey asking students whether they plan to attend college, travel, or both after high school. A 4-column table with 3 rows. The first column has no label with entries travel, not travel, total. The second column is labeled college with entries 43, 24, 67. The third column is labeled not college with entries 10, 5, 15. The fourth column is labeled total with entries 53, 29, 82. Which is the marginal relative frequency for students who plan to attend college? Round the answer to the nearest percent. 18% 22% 35% 82%

Answers

Answer: 82%

Step-by-step explanation:

- - - - - - - - college - - not college - - - - total

Travel - - - - 43 - - - - - - - 10 - - - - - - - - 53

Not travel - 24 - - - - - - - 5 - - - - - - - - - 29

Total - - - - 67 - - - - - - - 15 - - - - - - - - - 82

Marginal relative frequency of students who plan to attend college:

(Number of students who plan to attend the college / Total number of the students)

Number of students who plan to attend college = 67

total number of students = 82

Marginal relative frequency = 67/82

= 0.8170731

= (0.8170731) * 100%

= 81.7% = 82%
