Answer:
18 students took the bus to school.
Step-by-step explanation:
If 1/4 of the students walked, that leaves 3/4 of the students who did not walk. That leaves 22.5 students. Out of these students 22.5, 4/5 of them take the bus, and 4/5 of 22.5 is 18.

Evaluate the expression 15g if g = 1/5.
Answer:
3
Step-by-step explanation:
15g
g=1/5
15×1/5
15/1×1/5=3
Answer:
3
Step-by-step explanation:
This is the answer because:
1) We have to substitute the value into the equation:
15(1/5)
2) Next, we have to mutiply 15 and 1/5 together since the g is just a variable that is supposed to be mutiplied with 15:
15(1/5) = 15/5 = 15 ÷ 5 = 3
Therefore, the answer is 3.

A barrel contained 60 gallons of water. Water leaked out of the barrel at a rate of 6 gallons every 3 days. At this rate, how many days did it take for all 60 gallons of water to leak out of the barrel?
Please can someone help????
Proof:
Consider [tex]\triangle WXZ, \triangle YZX:[/tex]
[tex]\overline W\overline X = \overline Y\overline Z[/tex] (given)
[tex]\angle WXZ = \angle YZX[/tex] (alternate angles are equal, [tex]\overline W\overline X\parallel \overline Y\overline Z[/tex])
[tex]\overline Z \overline X[/tex] is a common side
∴ [tex]\triangle WXZ \cong \triangle YZX[/tex] (SAS)

Emma's grandmother sent her an $80 bookstore gift card for her birthday. Emma wants to make sure that her purchases don't exceed the amount of her gift card. So far, she has selected books that cost $8.95, $11.95, $22.25, and $24.95. She has also found a calendar she likes for $8.25. Round each item up to the next dollar to overestimate the total cost of the items in Emma's shopping basket.
Answer: total cost of the estimated items = $76
Step-by-step explanation:
Step 1
Rounding up each item to the next dollar
Book 1 = $8.95 ≈ $9.00
Book 2 = $11.95≈ $12.00
Book 3 = $22.25≈$22.00
Book 4 = $24.95≈$25.00
Calendar = $8.25 ≈$8.00
Step 2
The total estimated cost of items in Emma's shopping basket =$9.00+$12.00+$22.00+$25.00+$8.00
=$76 which did not exceed the amount of bookstore gift card of $80 sent by her grandmother.
Answer: 78$
Actual Estimate
$8.95 --------------------------$9.00
$11.95--------------------------$12.00
22.25--------------------------$23.00
$24.95------------------------$25.00
$8.25--------------------------$9.00
Then add the estimate numbers to get $78

Step-by-step explanation:
Josie has $30 to spend at a festival .It cost $5 to enter the festival and the game she wants to play cost $1.40 .Write the inequality and use it to determine the number of games that Josie can play
Answer:
At the maximum Josie can be 17 games.
Step-by-step explanation:
Given that:
Total money available with Josie to be spent at a festival = $30
Entry ticket for the festival = $5
Ticket for each game = $1.40
To find:
The inequality to represent the situation and the number of games that Josie can play.
Solution:
Ticket for 1 game = $1.40
Let [tex]n[/tex] number of games can be played.
So, Ticket for [tex]n[/tex] games = $1.40[tex]n[/tex]
Total money spent = $1.40[tex]n[/tex] + $5
It is should be lesser than or equal to $30.
[tex]1.40n + 5 \leq 30\\\Rightarrow 1.40n \leq 25\\\Rightarrow n \leq 17.8[/tex]
Therefore, at the maximum Josie can be 17 games.

f the line with equation y=−2x+7 is rotated 90° clockwise about the origin, what are the coordinates of the image of its y-intercept?
A. (2,0)
B. (7,0)
C. (0,−7)
D. (−7,0)
Answer:
B
Step-by-step explanation:
I looked it up
The line with equation y=−2x+7 is rotated 90° clockwise about the origin, the coordinates of the image of its y-intercept is D (−7,0).
What is y-intercept of a function?The intersection of the graph of the function with the y-axis gives y-intercept of that function.
The y-intercept is the value of y on the y-axis at which the considered function intersects it.
Assume that we've got: y = f(x)
At y-axis, we've got x = 0, so putting it will give us the y-intercept.
Thus, y-intercept of y = f(x) is y = f(0)
To find the y-intercept of the line y=-2x+7. When x=0 we have that y=-2·0+7, y=7,
then point (0,7) is the y-intercept.
When we rotate this line 90° clockwise about the origin, then point (0,7) will be placed on the x-axis in positive x-direction.
Rotation preserves the distances, then the coordinates of the image are (7,0).
The correct choice is D (−7,0).

Please help me circles.....
Answer:
95
Step-by-step explanation:
The equation is
x×2=285-x
3x=285
x=95
Answer:
x = 75°
Step-by-step explanation:
There are many Circle Geometry Rules. We will be using the following:
The angle at the centre of the circle is twice the angle at the circumference.
x = the angle opposite 285 - x.
This means that 360 - (285 - x) = 2x
360 - 285 + x = 2x
75 + x = 2x
We can simplify this by taking away x from both sides.
75 = x
We can check this by substituting x into the orginal equation.
360 - (285 - x) = 2x
360 - (285 - 75) = 2 * 75
360 - 210 = 2 * 75
150 = 2*75
150 = 150
How to find the discount
Can you solve this by explaining.
Answer:
The answer is 1
Step-by-step explanation:
Start by solving the division part of the equation. In order to do that, you have to flip the fraction (reciprocal) and switch from division to multiplication, thus getting 3 x 3 = 9. Now you have 9 – 9 + 1, and from there you can simply work from left to right and get your final answer: 1.

Jerry has a part-time job at a supermarket. The ordered pairs show the number of hours he worked for (input values) and the number of dollars (output values) he earned over a five week period. (6,72) (8,96) (5.5, 66) (9,108) (7,84) Are the ordered pairs a relation?
Answer:
Yes
Step-by-step explanation:
The ordered pairs are (6,72) (8,96) (5.5, 66) (9,108) (7,84).
The number of hours worked is [tex]x[/tex] and the money earned is [tex]y[/tex].
Let us divide the values of [tex]y[/tex] by [tex]x[/tex]
[tex]\dfrac{72}{6}=12[/tex]
[tex]\dfrac{96}{8}=12[/tex]
[tex]\dfrac{66}{5.5}=12[/tex]
[tex]\dfrac{108}{9}=12[/tex]
[tex]\dfrac{84}{7}=12[/tex]
The fuction which defines the above ordered pairs is [tex]y=12x[/tex]
It can be seen that the amount of money earned is 12 times the number of hours worked.
So, per hour Jerry earns 12 dollars.
Hence, the ordered pairs are relation.
