<u>Answer:</u>

The total number of hours Jamie volunteered at a nursing home is 15 hours

<u>Solution:</u>

Jamie volunteered at a nursing home for 6 days.

She volunteered 2\frac{1}{2} hours each day at the nursing home.

We have been asked to find out the total number of hours she has volunteered at the nursing home.

We can rewrite 2\frac{1}{2} in decimal form to simplify the calculation.

=2 \frac{1}{2}=\frac{5}{2}=2.5

Therefore, Jamie volunteered 2.5 hours at the nursing home each day.

To find out the total number of hours she has volunteered there, we have to do the following:

\text { Total hours volunteered }=\text { total no. of days volunteered } \times \text { no. of hours volunteered. }

=6 \times 2.5=15

So, the total number of hours Jamie volunteered at a nursing home is 15 hours.

Asa received scores of 72, 97, and 82 on her last three math tests. she needs a mean test score of 82 to qualify for the math te
lara [203]

First step is to find what should be the required total of sum of Score after fourth test, to identify how much more or less she need to score in his fourth test.

Since Mean = (Sum of Scores)/number of test

using above formula we determine what is the required sum of score.

82 = (Sum of Scores)/4

⇒ 82 × 4 = 328

So in four test she should have score total as 328

So Score require in fourth test = Required Score Total - (total score in 3 tests)

             = 328 - ( 72 + 97 + 82 ) = 77

So she need score of 77 to be at mean of 82 after fourth test and get qualify for the team

What are the coordinates of the point on the directed line segment from (-6, -6)(−6,−6) to (9, -1)(9,−1) that partitions the seg
GrogVix [38]

Answer:

(0, -4)

Step-by-step explanation:

The coordinates of the points from which the directed line segment extends = (-6, -6) to (9, -1)

The ratio the required point partitions the line = 2 to 3

The formula for finding the coordinate of a point that partitions a line AB into a ratio 'a' to 'b', where the coordinates of, A = (x₁, y₁) and B = (x₂, y₂) is given as follows;

\left(\dfrac{a}{a + b} \times (x_1 - x_2)+ x_1, \ \dfrac{a}{a + b} \times (y_1 - y_2)+ y_1 \right)

Therefore, the required point is located as follows;

\left(\dfrac{2}{2 + 3} \times (9 - (-6))+ (-6), \ \dfrac{2}{2 + 3}\times (-1 - (-6))+ (-6) \right) = (0, -4)

The coordinates of the point is (0, -4)

-x + 4y when x = -4/5 and y = 1/3
Usimov [2.4K]

we have the expression

-x+4y

Evaluate for x=-4/5 and y=1/3

substitute the values of x and y in the given expression

\begin{gathered} -(-\frac{4}{5})+4(\frac{1}{3}) \\ \frac{4}{5}+\frac{4}{3} \\ \frac{3\cdot4+5\cdot4}{15} \\ \frac{32}{15} \end{gathered}

the answer is 32/15

A store is designing the space for rows of nested shopping carts. Each row has a starting cart that is 4 feet long, followed by
stich3 [128]

Answer:

Each nested carts is of the length of 1.5 feet.

Step-by-step explanation:

Each row has a starting cart that is 4 feet long, and the nested carts are next to it.  

It is measured that a row of 13 nested carts has a length of 23.5 feet.

Therefore, the original length of 13 nested carts is (23.5 - 4) = 19.5 feet.

So, each nested cart add to the length of the row, \frac{19.5}{13} = 1.5 feet.

Again, a row of 18 nested carts to be 31 feet long.

Therefore, the actual added length of 18 nested carts is (31 - 4) = 27 feet.

So, each nested cart add to the length of the row, \frac{27}{18} = 1.5 feet.

So, each nested carts is of the length of 1.5 feet. (Answer)
