( I need it by 10/20)
=====================================================
Explanation:
C is the midpoint of AB. This means AC is half as long as AB
Put another way, AB is twice as long as AC
AB = 2*AC
AB = 2*( AC )
32 = 2*( x/2 + 10 ) .... substitution
32 = 2*(x/2) + 2*10 ... distribute
32 = x + 20
x+20 = 32
x = 32-20 .... subtract 20 from both sides
x = 12
---------
If x = 12, then
AC = x/2 + 10
AC = 12/2 + 10
AC = 6+10
AC = 16
which is half of AB = 32, so it confirms our answer.

3b) Two pizzas are made to the same dimensions. The only difference is that
Pizza 1 is cut into pieces at 30° angles and Pizza 2 is cut at 45° angles. They are
sold by the slice. The slices for Pizza 1 sell for $1.45/slice and the slices for Pizza 2
sell for $1.75/slice. What is the difference in total sales between Pizza 2 and Pizza
1?
Step-by-step explanation:
$0.30 because they only sell 30 cents less/more than each other
The original price of a jacket was 72.50$ Maria used a coupon for 20% off to buy the jacket. How much did she pay before tax?
Answer: Maria payed $58.00 for her jacket BEFORE tax.
Step-by-step explanation:
To find the answer to this question, we must first multiply 72.50 by 0.20. After doing so, we get 14.5 (this is the sale money). Finally, we subtract $72.50-14.5 to get out answer, 58 dollars.
The slope of the line in Problem 3 was (-2, -3) to write an equation of the line in point-slope form.
Answer:
solve this example and then you will know how to solve your question
Step-by-step explanation:
Example of one**-
Explanation:The equation of a line in
point-slope form is.
where m represents the slope and (x1,y1)
a point on the line
here m=5 and
y+1=5(x+2)
(x1,y1)=(−2,−1)⇒
y−(−1)=5(x−)(−2)⇒y+1=5(x+2)
is equation in point-slope form
distributing and collecting like terms gives another version of the equation.
y+1=5x+10⇒y=5x-9←
in slope-intercept form
A line contains the points (82, -96) and (87, -86)
What is the slope of the line in simplified form?
A. -2
B. 1/2
C. 2
D. -1/2
==================================================
Explanation:
Subtract the y coordinates
y1-y2 = -96-(-86) = -96+86 = -10
Subtract the x coordinates in the same order
x1-x2 = 82-87 = -5
Divide the two differences to get the slope m
m = (y1-y1)/(x1-x2)
m = -10/(-5)
m = 2
You could also use the formula
m = (y2-y1)/(x2-x1)
to get the same result. All that matters is that you subtract in the same order for the x and y coordinates.

In this case, the opportunity cost for (refurbishing the gym, upgrading the computer lab, or getting new instruments.) was ( upgrading the new computer lab hardware, getting new equipment, or getting new instruments?
Answer:
getting new instrument
Explanation:
Note that the term opportunity cost refers to the value or the cost of not selecting/benefitting from the other alternative option.
Comparing both budgets, it is observable that the budget for computer lab hardware was increased by 5%; and that of musical instruments was reduced by 5% according to The Northville School Board order of preference (importance).
Thus, we can say that the board decided to forgo some of the amount spent on musical instruments, but decided to increase spending on computer hardware.
Answer:
In this case, the opportunity cost for upgrading the computer lab hardware was getting new instruments.

Step-by-step explanation:
Find the equation of the line passing through the given points. Express the equation in standard form.
(1,-6) and (-7,2)
We want to write the equation of the line passing through these two points in standard form.
First, we are going to do this in slope intercept form and then change the form to standard form, which is Ax + By = C
We will use the equation y = mx + b, and since we are given two points on the line we are going to determine the slope of the line by determining the change in the y coordinates
m = y sub2 - y sub1 divided by the change in the X coordinates x sub2 – x sub1
We will start by determining the slope
(1, -6) the 1 is x sub 1 and the 6 is y sub 1
(-7, 2) the -7 is x sub 2 and the 2 is y sub 2
2 - (-6) = 8
-7 -1 = -8
so equation now is m = -1
So now again referring back to the slope intercept of the line we now know y = -1 + b. We still have to determine b and the y intercept, and we can do this by using one of the given points and substituting in the value for y and x, and then solve for b. Since these points are on the line, they must satisfy this equation. If we use the first coordinates, we would substitute 1 for x and -6 for y.
-6 = -1 times x, which is 1 + b
b = -5
construct the line equation y = mx + b where m = -1 & b = -5
In slope intercept form the equation would be y = -x - 5
Now we want to write this in standard form now. We have to deal with two things. The x and y terms have to be on the left side and A and B and C have to be integers.
The standard form of a linear equation is Ax + By=CA x + By = C . Move all terms containing variables to the left side of the equation.
Add x to both sides of the equation.
y + x = -5
Reorder y & x
x + y = -5

Based on the observations above, it is clear that an appropriate domain for the function is
.
Answer:
[tex]f(0) = 0[/tex]
[tex]f(70) = 16.74[/tex]
[tex]f(58.5) = 15.30[/tex]
[tex]x \geq 0[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 2\sqrt x[/tex]
Solving (a): f(0)
[tex]f(x) = 2\sqrt x[/tex]
[tex]f(0) = 2 * \sqrt 0[/tex]
[tex]f(0) = 2 * 0[/tex]
[tex]f(0) = 0[/tex]
Interpretation:
This implies that, the cost of 0 paints is $0
Solving (b): f(70)
[tex]f(x) = 2\sqrt x[/tex]
[tex]f(70) = 2 * \sqrt{70[/tex]
[tex]f(70) = 2 * 8.37[/tex]
[tex]f(70) = 16.74[/tex]
Interpretation:
This implies that, the cost of 70 paints is $16.74
Solving (c): f(58.5)
[tex]f(x) = 2\sqrt x[/tex]
[tex]f(58.5) = 2 * \sqrt{58.5[/tex]
[tex]f(58.5) = 2 * 7.65[/tex]
[tex]f(58.5) = 15.30[/tex]
Interpretation:
This implies that, the cost of 58.5 paints is $15.30
Solving (d): The domain
[tex]f(x) = 2\sqrt x[/tex]
Set the radicand x to [tex]\geq 0[/tex]
i.e.
[tex]x \geq 0[/tex]
Hence:
The domain is [tex]x \geq 0[/tex]
I have tried to answer it over and over again but never got the right anser
Answer:
#1) 25 degrees #2) 155 degrees #3) 25 degrees #4) 25 degrees #5) 5x+15= 110
Step-by-step explanation:
basically the use the vertical angle relationship to figure it out
that would mean that 4=155 and 3=1 and since the relationship is straight angle pair it means that 155+ x= 180 180-155= 25
5) CDE= FDG this is the vertical angle rule so 5x+15= 8x-42
solve that by adding like terms, 5x-15= 8x-42 +15 by doing adding to both sides it eliminates the 15 because you added it with the like terms, -42 and got -57
-57+8x= 5x now subtract 8 on both sides, -57= -3x divide and it equals 19
now plug that back into the eqaution of 5x+15 5(19)= 95 + 15= 110

Answer:
The average rate of change in grams from day 4 to day 7 is approximately 0.11 grams/day
Step-by-step explanation:
The table for the radioactivity in iodine-131 can be presented as follows;
[tex]{}[/tex] [tex]{}[/tex]Radioactivity in iodine-131

The average rate of change in grams from day 4 to day 7 is given as follows;
[tex]The \ rate \ of \ change \ from \ day \ 4 \ to \ day \ 7 = \dfrac{F(7) - F(4) }{7 - 4} = \dfrac{1.09 - 1.41 }{7 - 4} =-\dfrac{8}{75}[/tex]
The average rate of change in grams from day 4 to day 7 = -8/75 ≈ 0.11 g/day
The average rate of change in grams from day 4 to day 7 ≈ 0.11 grams/day rounded to the tenths place.
The average rate of change in grams per day from day 4 to day 7 is 0.11.
Calculation of the average rate of change:Radioactivity in iodine-131

Now the average rate should be
= F(7) - F(4) \ 7 - 4

Answer:
The answer would be -10p+30.
Step-by-step explanation:
Distrubuting the 5 to -3p and 7 and 5 to p and -1 would be the first step.
Once you did that, you would get -15p+35+5p-5. Now just add -15p to 5p and add 35 to -5 and you'll get -10p+30.

Sam bought brushes for $8, a palette for $5, and oil paints for $15. He paid $29.82 in all. What sales tax rate did Sam pay?
A.
0.06%
B.
0.65%
C.
6.5%
Answer:
6.5%
Step-by-step explanation:
Total cost before tax
= Cost of Brushes + Cost of Palette + Cost of paint
= 8 + 5 + 15
= $28.00
It is given that in total, he paid $29.82
Hence the amount he paid in taxes
= Total amount paid - total cost before tax
= $29.82 - $28.00
= $1.82
Therefore, sales tax rate
= (taxes / cost before tax ) x 100%
= (1.82 / 28) x 100%
= 6.5%
Answer:
C)6.5%
Step-by-step explanation:
so first you have to add up all the items, then u get 28.00, then what i did was i subtracted 29.82 and 28.00 i got 1.82. and 6.5 equals 1.82 so yea.
