Answer:

76

Step-by-step explanation:

We were given The equation below which shows how much money was raised with t tickets sold. $836 = $11t

Mathematically, unit rate is How much of something per 1 unit of something else

$836 = $11t

Then we can get the value for "t" as

t= 836/11

t= 76

Hence, Unit rate is 76

Answer:the answer is 34

Step-by-step explanation:

Answer:

34

Step-by-step explanation:

Combine 34 and x . Since the equation can be written in the form y=kx y = k x , y varies directly with x and k . The constant of variation, k , is 34

The average rate of change of a continuous function f(x) in an interval (a, b) is

(f(b) - f(a)) / (b - a)

So for

f(x) = 3x ² + 2x + 5

on the interval (0, 2), we have

• f (2) = 3 • 2² + 2 • 2 + 5 = 21

• f (0) = = 3 • 0² + 2 • 0 + 5 = 5

so that the average rate of change is

(f (2) - f (0)) / (2 - 0) = (21 - 5) / 2 = 16 / 2 = 8

and the answer is B.

Step-by-step explanation:

85+9=94 85 times 2= 170

Answer:

Step-by-step explanation:

Justin has 19

Nicole has 28

Shen has 38

Answer:

a. y = 7x-98  

y =-3/5x-2  

b. y =-1/3x+4/3  

x =-21

Step-by-step explanation:

a.  7x - y = 98

98 - 7x

-y = -7x + 98

divide by -

y = 7x - 98

3x - 5y = 10

10 - 3x

-5y = -3x + 10

divide by -5

y = -3/5x - 2

b.  x + 3y = 4

4 - x

3y = -1x + 4

divide by 3

y = -1/3x + 4/3

x = 6- 27

x = -21

Answer:

The width of the rectangle is 7 units

Step-by-step explanation:

Here, we want to find the width of the rectangle

Mathematically, the area of the triangle is length * width

(2x + 1)(2x-1) = 35

4x^2 - 1 = 35

4x^2 = 36

x^2 = 9

x = 3

Substituting 3 in 2x + 1

we have 2(3) + 1 = 6 + 1 = 7 units

Answer: $9.20

Step-by-step explanation: To get the answer, you add both the cost and multiply it by .15. Then you add the product to the number you got adding the cost of the food.

Answer:

$1.20

Step-by-step explanation:

He has to leave 100% of the cost which is $5.50 + 2.50 or $8.00.

He wants to leave 115% of the $8 he has to leave.

So you set it up like

x/8 = 115/100

Then you solve for x

8(115) = 920

920/100 =9.2

So he will leave $9.20.

It then asks for just how much the tip is that he will leave so

9.2 - 8 = 1.2

So the tip is $1.20.

Answer:

Step-by-step explanation:

-19=-17+k/5

add 17 to both sides

-2=k/5

multiply by 5 on both sides to get k alone

k=-10

Answer:

okay so if - 19 is equal to 17 + k divided by 5, first you figure out what you have to do to 17 to get -19. in this case, all you do is subtract 17 from 17 to get 0, then subtract 19 from 0 to get -19. then you add 17 and 19 to see how much you subtracted from 17 to get -19, so you subtracted 36 from 17. now you add the - sign to the 36 so that means instead of subtracting a positive number you're adding a negative number (it has the same effect) so you now need to know what, when divided by 5, equals -36. so just multiply -36 by five to get -180. so k = 170

Step-by-step explanation:

-19 = 17 + -180/5

-180/5 is -36

-19 = 17 + -36

17 + -36 = -19

-19 = -19

(sorry this is a lot of info but its harder to explain if i cant say a lot)

Answer:

The value of k is 1

Step-by-step explanation:

If x-1 is a factor, if we equate x - 1 to 0 and substitute the value of x

Then, we should have 0 as the f(x) value

so;

x-1= 0

x = 1

Substitute this

0 = 1^3 + k(1) - 2

0 = 1 + k-2

0 = k-1

k = 1

Answer:what grade is this?

Step-by-step explanation:

Answer:

7 Units

Step-by-step explanation:

Answer:

55 degrees.

Step-by-step explanation:

ok so first off we know altogether the angles of a triangle have to equal 180 degrees total we have one thats 80 so the other two together must be 100 given that information we can make the equation 7x+6+3+6x=100 we simplify to get 13x+9=100 after moving it around you get 13x=91 solve the equation by dividing both sides by 13 to get x=7, but we are not done we have to solve for angle A by inputting the X so we get angle A=55 degrees

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

Work Shown:

A+B+C = 180 ..... angles of a triangle add to 180

(7x+6) + (80) + (3+6x) = 180

13x + 89 = 180

13x = 180-89 .... subtract 89 from both sides

13x = 91

x = 91/13 .... divide both sides by 13

x = 7

Use this x value to find the missing angle measures.

angle A = 7x+6 = 7*7+6 = 55

angle C = 3+6x = 3+6*7 = 45

Note that,

A+B+C = 55+80+45 = 180

which helps confirm our answer.

Answer:

9. C. $2.00

10. B. $18.00

11. C. $1.53

12. A. $19.53

Step-by-step explanation:

10%, or 1/10th of 20 dollars is 2 dollars.

The movie, therefore, will cost 2 dollars less, or 18 dollars before tax.

To find tax, multiply the total (after price reduction) by the percentage tax (as a decimal, 0.085%), which gives you 1.53.

Add the tax and the initial cost together to get the total cost.
