A rectangle is 1 cm more than twice its width. Find the dimensions of the rectangle if it’s area is 45 cm show all work
Answer:
Step-by-step explanation:
L=2W+1
A=L*W
A=(2W+1)*W=45
We have two mathematical solutions, but only one viable
2W^2+W=45
w=-5 not valid
w=4.5 cm valid solution
L=10cm

Lins father is paying for a $20 meal. He has a%15 off coupon for the meal. After the discount, a 7% sales tax is applied. What does Lin's father pay for the meal
Answer:
he pays $18.19 hope this helps have a nice day please give me brainliest
Step-by-step explanation:
Answer:
$14.55
Step-by-step explanation:
First you determine how much 15% of 20 is. That is $3.
Then you subtract that much from 20 (which is $17.00)
Then you figure out how much 7% of 17 is. That is $1.19.
Finally, you add the tax to $17.00 to get $18.19.
Final Answer: $18.19

A club raised 175% of its goal for a charity. The club raises $875. What was the goal?
Pls help and thank you
Answer: The goal was $500
======================================================
Work Shown:
x% = x/100
175% = 175/100 = 1.75
Let g be the goal, which is the amount of money the club wanted to raise
175% of goal = 175% of g = 1.75g
The expression 1.75g represents how much money was actually raised, which was $875. Set the two expressions equal to each other. Solve for g
1.75g = 875
g = 875/1.75 ....... divide both sides by 1.75
g = 500
The club's goal was to raise $500
Note how 75% of $500 is 0.75*500 = 375
When they raised 175% of the goal, this means they went 75% overboard and added on 375 additional dollars (on top of the 500 they wanted). So they got to 500+375 = 875 which lines up with the instructions. This helps verify the answer.
Or we can see that 1.75*g = 1.75*500 = 875 which helps confirm the answer as well.
Jimmy and Alex each have a CD collection. • The number of CDs in Jimmy's collection can be represented by x. • The number of CDs in Alex's collection is 4 times the number in Walter's collection. • The total number of CDs in both collections is 205. What is x, the number of CDs in Walter's collection?
Answer:
x = 41
And, the number of CDs in Walter's collection is 41
Step-by-step explanation:
The computation is shown below;
Given that
The number of CDs in Jimmy collection = x
The number of CDs in Alex's collection = 4x
And, The total number of CDs in both collections is 205
So, the equation is
x + 4x = 205
5x = 205
x = 41
The alex collection is
= 4 × 41
= 164
So, the walter collection is
= 164 ÷ 4
= 41
If the sum of base angle of isosceles triangle
is 88° calculate the other angle
Answer:
92
Step-by-step explanation:
The sum of the three angles of a triangle is 180
We know the sum of the base angles is 88
180 = 88+x
180 -88 =x
92=x
The other angle is 92
Answer:
92°is other angle of isosceles triangle
HELP QUICK
Write the equation of a line that is parallel to the graph of 3y = 2x − 3 and passes through the point
(−3, 4).
Answer:
y = 2/3x + 6
Step-by-step explanation:
First, put the original equation in y = mx + b form
3y = 2x − 3
y = 2/3x - 1
The slope of the other line will also be 2/3, since parallel lines have the same slope.
Plug in this slope and the given point into y = mx + b, and solve for b:
y = mx + b
4 = 2/3(-3) + b
4 = -2 + b
6 = b
Plug in the slope and b:
y = 2/3x + 6 is the equation of the line

Each statement describes a transformation of the graph of y= x.
Which statement correctly describes the graph of
y= x - 8?
A. It is the graph of y= x translated 8 units to the left
B. It is the graph of y= x translated 8 units up.
C. It is the graph of y=x translated 8 units down.
D. It is the graph of y=xwhere the slope is decreased by 8.
Answer:
c
Step-by-step explanation:
its in slope intercept form, or y=mx+b where b is the y intercept, i.e. how far down the line hits the y axis. m would be the slope but we dont need to worry about that for now. since b is the y intercept, -8 would mean 8 units down

There are 21 jars of peanut butter for sandwiches. Each sandwich uses 1/5 of a peanut butter jar. How many sandwiches can be made from all the peanut butter?
Answer: 105 sandwiches can be made from all the peanut butter.
Step-by-step explanation:
Given: Total jars of peanut butter = 21
Part of peanut butter required for each sandwich = [tex]\dfrac15[/tex]
Total number of sandwiches made = ( Total jars of peanut butter ) ÷ (Part of peanut butter required for each sandwich)
[tex]=21\div\dfrac15\\\\=21\times5\\\\=105[/tex]
Hence, 105 sandwiches can be made from all the peanut butter.

Liz and Larry are arguing over who makes better chocolate chip cookies. Liz likes to use 3 cups of brown sugar for every 8 cups of flour. Larry prefers to use 2 cups of brown sugar for every 5 cups of flour. Do Liz and Larry use the same ratio of brown sugar to flour?
Answer: No, they don't.
Step-by-step explanation: Liz uses a 3 to 8 ratio of brown sugar to flour while Larry uses a 2 to 5 ration of brown sugar to flour. I hope this helps!
Answer:
The answer is no
Step-by-step explanation:
It is imposibble for Liz and Larry to use the same ratio of brown sugar to flour,
The rotio of liz cup = 3:8
the ratio of larry = 2:7
The ratio of liz cup is greater than the ratio of larry.
so they are deffinetly not the same ratio,
therefore the answer is No

What is the y-intercept of this function?
2.25
4.00
6.50
17.13
Answer:
4.00
Step-by-step explanation:
Given
x: 2 , 5 , 8 , 12
y: 8.50, 15.25, 22.00. 31.00
Required
Determine the y intercept
First, we calculate the slope:
[tex]m = \frac{y_2- y_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,y_1) = (2,8,50)[/tex]
[tex](x_2,y_2) = (12,31.00)[/tex]
[tex]m = \frac{31.00 - 8.50}{12 - 2}[/tex]
[tex]m = \frac{22.5}{10}[/tex]
[tex]m = 2.25[/tex]
Next, we calculate the equation:
[tex]y - y_1 = m(x - x_1)[/tex]
Where:
[tex](x_1,y_1) = (2,8,50)[/tex]
[tex]m = 2.25[/tex]
The equation becomes:
[tex]y - 8.50 = 2.25(x - 2)[/tex]
[tex]y - 8.50 = 2.25x -4.5[/tex]
Make y the subject
[tex]y = 2.25x -4.5+8.50[/tex]
[tex]y = 2.25x +4[/tex]
Take [tex]x =0[/tex]; to get the y intercept
[tex]y = 2.25*0 +4[/tex]
[tex]y = 4[/tex]
Hence, the y intercept is 4.00
