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.

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

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.

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.

Now the average rate should be

= 1.09-1.41 \3

= -8\75

= 0.11

hence, The average rate of change in grams per day from day 4 to day 7 is 0.11.

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

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.

Answer:

A

Step-by-step explanation:

==================================================

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.

A. 1 2/3

Step-by-step explanation:

−4 1/3

1 2/3

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
