Answer:
-8
Step-by-step explanation:
Let r, g and c be the scores of, respectively, Rose, Garcia and Curran.
We know that
[tex]r + g + c = - 32 \\ r = - 9 \\ g = - 15[/tex]
Thus
[tex] - 9 - 15 + c = - 32 \\ - 24 + c = - 32 \\ c = - 8[/tex]
A car traveled 25 miles in 1/5 of an
hour. At the same speed, how many
miles will the car travel in 1 hour?
Answer:
in 1 hour it can travel 5(25)= 125 miles
Answer:
125 miles
Step-by-step explanation:
1/5 of a n hour = [tex]\frac{1}{5}*60[/tex] = 12 minutes
Distance traveled in 12 minutes (1/5 of an hour) = 25 miles
Distance traveled in 1 minutes = 25 ÷ 12 = [tex]\frac{25}{12}[/tex]
Distance traveled in 1 hour (60 minutes) = [tex]\frac{25}{12}*60 = 25*5 = 125 miles[/tex]

The topology taxi company charges 2.60 for the first quarter of a mile and 0.36 for each additional fifth of a mile. Find a linear function which models the taxi fare F as a function of the number of miles driven m
Answer:
The piecewise function for the taxi fare is:
[tex]F(t) = 2.60\cdot \left(\frac {m}{0.25}\right) ,\, 0\,mi\le m \le 0.25\,mi[/tex]
[tex]F(t) = 2.60 + 0.36\cdot \left(\frac{m}{0.2} \right)[/tex], [tex]m > 0.25\,mi[/tex]
Step-by-step explanation:
We must use the following piecewise function:
(i) The Topology Taxi Company charges 2.60 for the first quarter of a mile:
[tex]F(t) = 2.60\cdot \left(\frac {m}{0.25}\right) ,\, 0\,mi\le m \le 0.25\,mi[/tex] (1)
Where:
[tex]F(t)[/tex] - Taxi fare, in monetary units.
[tex]m[/tex] - Number of miles driven, in miles.
(ii) And 0.36 for each additional fifth of a mile:
[tex]F(t) = 2.60 + 0.36\cdot \left(\frac{m}{0.2} \right)[/tex], [tex]m > 0.25\,mi[/tex] (2)
If h(x) = 2x and k(x) = 2x - 4, what is h(k(x))?
To find h(k(x)), substitute k(x) into h(x):
h(k(x)) = 2x
= 2(2x - 4)
= 4x - 8
Thus, h(k(x)) = 4x - 8 would be your final answer.

Describe the difference between a bar graph and a circle graph.
Answer:
Unlike most circle graphs, bar graphs compare exact amounts. Circle graphs are used when dealing with percentages, and the percentages of the pieces add up to 100 percent. In a bar graph, however, a scale is used to show the exact amount of each category. ... The bar graph shows the same results but in a different format.

What is the least common multiple of 6 and 10?
02
3
30
60
Answer: 30
Step-by-step explanation:
Multiples of 6:
6, 12, 18, 24, 30, 36, 42
Multiples of 10:
10, 20, 30, 40, 50
Therefore,
Least common multiple (6, 10) = 30
Answer:
30
Step-by-step explanation:
10 x 1 = 10 / 10 x 2 = 20 / 10 x 3 = {30}
6 x 1 = 6 / 6 x 2 = 12 / 6 x 3 = 18 / 6 x 4 = 24 / 6 x 5 = {30}
The least common multiple of 10 and 6 is 30
A nursery owner buys 7 panes of glass to fix some damage to her greenhouse. The 7 panes cost
$15.05. Unfortunately, she bredks 3 more panes while repairing the damage. What is the cost of
another 3 panes of glass?
Answer:
Its 6.45
Step-by-step explanation:
we first need to know how much is one pane of glass so i divide
15.05÷ 7 and got $2.15
so each one pane of glass is $2.15
than i multiply 2.15 x 3 and got 6.45
So the cost is 6.45

Answer:
A.) 3/10
Step-by-step explanation:
I added all the colored cubes together (4+6+3+7=20) then I put the number of green cubes (6) over the total (20) so it looks like 6/20. But that can be simplified to 3/10.
Hope I helped! (p.s. Maybe brainliest)
Answer:
3/10Addition:
4 + 6 + 3 + 7 = 20
I put the number of green cubes
6 over the total
20
= 6/20
However, this can be simplified to 3/10.

Answer:
the student may have made the mistake because the student was paying more attention to how many blocks he was filling in rather than how much he was filling in.
to solve the problem correctly you would just switch the decimals
0.8 > 0.08
0.8 should have 80 blocks filled
0.08 should have 8 blocks filled

The answer is 1 day and 7 items.
Ariana
y = 5x + 2
Julie
y = 7x
The ys have to be the same so equate the right hand side.
7x = 5x + 2 Subtract 5x from both sides.
7x - 5x = 5x - 5x + 2
2x = 2 Divide by 2
2x/2 = 2/2
x = 1

The perimiter of a rectangle is 128 inches. The width of the rectangle is 4y inches. Find the length of the rectangle in terms of y.
PLEASE HELP!
I will give brainiest if it is correct
Answer:
The perimeter of a rectangle is 2W + 2L.
P = 2W + 2L
128 = 2(4y) + 2L = 8y + 2L
2L = 128 - 8y
L = 64 - 4y (this is the answer
