yuson must complete a certian number of hours of community service. she does 2 hours of service each day. after 8 days, yuson has completed half of her required community service. write a linear equation to represent the hours that yuson has left to do after x days.
Answer:
y = 32 -2x
Step-by-step explanation:
You want an equation for the remaining community service Yuson must complete after x days if she does 2 hours per day and is half done after 8 days.
RemainingYuson has completed (2 hr/day)·(8 day) = 16 hr of community service after 8 days. This is half the total required, so the initial amount required must be 2·16 = 32 hours.
After x days, 2x hours have been completed, reducing the amount remaining. Thus the amount remaining is ...
y = 32 -2x . . . . . hours left after x days

Find equivalent ratios when the number of books ordered is 1, 2, and 3. Write them as ordered pairs in the form (x-coordinate, y-coordinate). Starting from the origin, explain how to plot the three equivalent ratios on a coordinate grid. (10 points)
Answer:
The equivalent ratios are: (1, 2), (2, 4), and (3, 6)
The graph can be plotted on a coordinate grid as shown in the diagram attached below.
Recall:
Ratio between two quantities, x and y, can be represented by the equation, y = kx, where k is the constant of proportionality.
k = y/x
Let x = number of books
y = cost (dollars)
Using any of the ordered pairs from the table, say, (7, 14), find k:
k = y/x = 14/7 = 2
Write the equation by plugging in the value of k into y = kx
y = 2x
Using the equation, y = 2x, find the equivalent ratios when x = 1, x = 2, and x = 3:
When x = 1:
y = 2(1) = 2 --> (1, 2)
When x = 2:
y = 2(2) = 4 ---> (2, 4)
When x = 3:
y = 2(3) = 6 ---> (3, 6)
The graph for the three equivalent ratios, (1, 2), (2, 4), and (3, 6) can be plotted on a coordinate grid as shown in the diagram attached below.

use the expression 6.3×15÷3±6.8-28.09
to create an expression that includes a
set of parentheses so that the value of
the expression is 46.25
Answer:6.3×(15÷3+6.8)-28.09
Step-by-step explanation: Hello!
6.3×15÷3±6.8-28.09
You should probably use addition instead of subtraction so let's try:
First try the expression 6.3×15÷3+6.8-28.09
You have to make a set of parentheses. You should probably not include 6.3 in the parentheses so you can multiply whatever is in the parentheses by 6.3. You should also probably not include -28.09 in the parentheses because you will make a negative number in the parentheses that won't be able to be made positive. Try:
6.3×(15÷3+6.8)-28.09
6.3(5 + 6.8)-28.09
6.3(11.8)-28.09
74.34-28.09
=46.25
This is correct!

Find the diameter of a circle if the circumference is 8 cm. Round to the nearest tenth.
Answer: 2.55
Step-by-step explanation:
To find the diameter you divide the circumference by pi (3.14).
The formula is d=c/π
8/3.14 is 2.547... and when rounded would be 2.55 or 2.6 if rounded.

Step-by-step explanation:Step-by-step explanation: Surface area of triangular prism = 2A + PH.
Lateral surface of a triangular prism = Length × (a + b + c)
i hope it helps u :-)
Answer:
Step-by-step explanation:
Area of triangle = bh/2
A = 4*5/2
A = 10 cm sq
A of 2 triangles = 10*2 = 20 cm sq
Now, Area of 1 rectangle = lb --> 10*5 = 50 cm sq
A of 3 rectangles = 50*3 = 150 cm sq
Now, LSA = 150 cm sq. (excluding the triangles)
TSA = A of tr. + A of rec. = 20 + 150 = 170 cm sq

Answer:13
Step-by-step explanation:
(y-7)²=36
Us PENDAS (Please Excuse My Dear Aunt Sally)
Multiply the exponent by 7-7x-7=49
this leaves your equation as(y+49)=36
do the opposite from the equation to the value giveny=49-36
Sum it upy=13
Hope this helps! Good luck!
Answer:
Step-by-step explanation:
√(y - 7)^2 = √36
y - 7 = +-6
----------------
y - 7 = 6
y = 13
-----------------
y - 7 = -6
y = 1
---------------
Therefore, y = 13 or y = 1
------------------------------------
There is no answer for y = 1, so we choose y = 13.

A spinner with repeated colors numbered from 1 to 8 is shown. Sections 1 and 8 are purple. Sections 2 and 3 are yellow. Sections 4, 5, and 6 are blue. Section 7 is orange.
A spinner divided into eight equal colored sections, with one orange, two purple, two yellow, and three blue.
Which statement about probability is true?
The probability of landing on blue is greater than the probability of landing on purple.
The probability of landing on yellow is less than the probability of landing on orange.
The probability of landing on orange is equal to the probability of landing on yellow.
The probability of landing on purple is equal to the probability of landing on blue.
Answer: The statement "The probability of landing on blue is greater than the probability of landing on purple." is true.
Answer:
I think "The probability of landing on blue is greater than the probability of landing on purple."

Answer:
Cubes needed to fill Prism 6: 116
The volume of Prism 6: 125
Step-by-step explanation:
First, multiply the length by the width. We can find these measurements by looking at the bottom diagonal line of the cubes.
Count how many sides are facing the front on the lowest side.
There are 5 squares facing forwards that are inside the Prism. Therefore the width/length is 5 cubic units.
Now count how many cubes it takes to go from the front side to the backside, or how many squares are facing the right. Remember this is a 3-dimensional object.
5 squares are facing the right, each belonging to the 5 cubes on the bottom of the prism.
Now count how many cubes are stacking. There are 5 cubes in the tower.
To find the volume, multiply all the measurements together.
Volume = Length x Height x Width (5 x 5 x 5)
Now to find how many cubes are needed to fill the prism, count how many cubes are already inside Prism 6.
Once you've found out how much the volume is, subtract the number of cubes inside the prism(9) from the volume(125).
125 - 9 = 116 cubes are needed to fill Prism 6.
Plot 2 1/3, −5/6, and −3 1/2 on the number line.
When plotting fractions on a number line, we need to figure out how much each tick mark is. See the photo attached for how to plot 2 1/3, –5/6, and –3 1/2 on the number line.
The number lineOn a number line,
the left side shows smaller numbers, and;the right side shows greater (bigger) numbers.This number line also has negative numbers. Each tick is still worth the same on the entire number line, but leftward of 0, the numbers become negative.
How much is each tick mark?The vertical markings on the number line are called tick marks.
To get from one whole number to the next whole number on the number line, we have to count 6 tick marks. This means that each tick is 1/6.
Plot 2 1/3The dot will be between 2 and 3.
First, find 2.
[tex]\frac{1}{3} =\frac{1*2}{3*2}=\frac{2}{6}[/tex] Since 1/3 = 2/6, we then move right (get bigger) by 2 ticks.
See the photo below for the plotted dot. 2 1/3 is in red.
Plot –5/6The dot will be between -1 and 0.
Start at 0. Then, move left (get smaller) by 5 ticks.
See the photo below for the plotted dot. – 5/6 is in green.
Plot –3 1/2The dot will be halfway between –3 and –4.
First, find –3. Then, move left (get smaller) by 3 ticks.
See the photo below for the plotted dot. –3 1/2 is in blue.
