Jogging is one of the few sports that has been consistently increasing over the past few years. The number of people jogging (in millions) from the years 2000 to 2009 is given by the equation y=x+22, where x is the number of years after 2000.

a. Use this equation or a graph of it to complete the ordered pair (4, ).
b. Write a sentence explaining the meaning of the answer to part (a).
c. If this trend continues, how many joggers will there be in 2021 ?

a. Complete ordered Pair
(4, )

Answers

Answer 1

Answer:

a. (4, 26)

b. The number of people jogging in 2004 was 26 million.

c. 43 million

Step-by-step explanation:

To complete the ordered pair, use the given first value of the pair as the value of the variable in the equation. Evaluate the equation to find the second value of the ordered pair:

y = x +22

y = 4 +22 = 26

The ordered pair is (4, 26).

The ordered pair tells you (years after 2000, number of joggers in millions). That means the ordered pair (4, 26) tells you 4 years after 2000, there were 26 million joggers.

21 years after 2000, the value of x is 21, so the value of y is ...

y = 21 +22 = 43

There will be 43 million joggers in 2021.

Find the question. 1/3 +(5/7)=

Answers

Answer:

22/21

Step-by-step explanation:

1/3 + 5/7

LCM of 3,7 = 3 x 7 = 21

1/3

= 1/3 x 7/7

= ( 1 x 7 )/( 3 x 7 )

= 7/21

5/7

= 5/7 x 3/3

= ( 5 x 3 )/( 7 x 3 )

= 15/21

1/3 + 5/7

= 7/21 + 15/21

= ( 7 + 15 )/21

= 22/21

22/21 is the answer I think

heresa earned scores of 88 points, 84 points, 88 points, and 91 points on four tests. What is the lowest score she can get on the fifth test and still finish with an average score of 90 points?

96 points
97 points
98 points
99 points

Answers

Answer:

99 points

Step-by-step explanation:

total of scores of 4 tests = 88 + 84 + 88 + 91 = 351

5 tests with an average score of 90:

⇒ total of scores = 5 × 90 = 450

Lowest score of 5th test = 450 - 351 = 99 points

Answer:

99 points

points scored:

88 points , 84 points, 88 points , 91 points, let the fifth test points be "n"

given score with an average 90 points

[tex]\sf \rightarrow \dfrac{88 +84+88+91+n}{5} =90[/tex]

[tex]\sf \rightarrow 351+n =90 (5)[/tex]

[tex]\sf \rightarrow n =450-351[/tex]

How do I get the answer??

Answers

Answer:

4√10

Step-by-step explanation:

Hello!

Let's first simplify the radical.

We can do this by expanding the radical:

We need to pull out a perfect square factor to expand a radical and simplify it. In 45, we have 9 and 5 multiplied, and 9 is a perfect square.

Let's work with √45:

√45 can be written as √9 * √5 (using the rule √ab = √a * √b)√9 simplifies to 3, so it is 3√5

Now we can simplify the operation in the parenthesis by combining like terms:

3√5 + √5√5 + √5 + √5 + √54√5

Now using the same rule as above, we can multiply the values:

√2(4√5)4√10

Your solution is 4√10

Brown presented these facts to the board of directors of the motel corporation and recommended that the corporation build a motel in the town of X at the location described. The board of directors agreed, and the new motel was constructed. The superhighway plans were changed, however, after the motel was constructed, and the highway was never built. Later, a packinghouse was built on property adjoining the motel, and the corporation sustained a considerable loss as a result. The shareholders brought an appropriate action against Brown, charging that his proposal had caused a substantial loss to the corporation and seeking recovery of that loss from Brown.
