Step-by-step explanation:

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:

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: 2,2 is not a solution

Step-by-step explanation:

Answer:

2 = (2/3)*(6)+b

2 = 4+b

b= -2

so slope intercept form is y = (2/3)x -2

To find the point slope form, simply plug in m and the point given.

y-2 = (2/3)*(x-6)

Step-by-step explanation:

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

Answer:

Yes

ΔDEF can be mapped to ΔRPQ by a 180° rotation about the origin followed by a translation 2 units down

Step-by-step explanation:

The coordinates of the vertices of the triangles are;

F(1, 0), D(1, 3), and E(5, 0), and Q(-1, -2), R(-1, -5), and P(-5, -2),

Length of FD = √((3 - 0)² + (1 - 1)²) = 3

Length of DE = √((5 - 1)² + (0 - 3)²) = 5

Length of FE = √((5 - 1)² + (0 - 0)²) = 4

For triangle QRP, we have;

Length of QR = √((-5 - (-2))² + (-1 - (-1))²) = 3

Length of RP = √((-5 - (-1))² + (-2 - (-4))²) = 5

Length of PQ = √((-5 - (-1))² + (-2 - (-2))²) = 4

For a reflection across the x-axis, we have;

For a rotation of 180° about the origin, we have;

For a coordinate of the preimage before reflection of (x, y), the coordinates of the image after reflection is (-x, -y)

When followed by a translation 2 units down, we have the coordinates of the image will be (-x, -y-2)

Therefore;

For the points F(1, 0), D(1, 3), and E(5, 0) on triangle FDE, we have;

Rotation 180° about the origin gives;

F(1, 0) → Rotation by 180° → F'(-1, 0)

D(1, 3) → Rotation by 180° → D'(-1, -3)

E(5, 0) → Rotation by 180° → E'(-5, 0)

For a translation 2 unites of the coordinates of the vertices of the above triangle ΔF'D'E',

F'(-1, 0) → Translation 2 units down → F''(-1, -2)

D'(-1, -3) → Translation 2 units down → D''(-1, -5)

E'(-5, 0) → Translation 2 units down → E''(-5, -2)

The coordinates of the vertices of triangle ΔF''D''E'' are equivalent to the coordinates of the ΔQRP

Therefore, ΔDEF, and ΔRPQ are congruent, because ΔDEF can be mapped to ΔRPQ by a 180° rotation about the origin followed by a translation 2 units down.

Answer:

Yes

ΔDEF can be mapped to ΔRPQ by a 180° rotation about the origin followed by a translation 2 units down

Step-by-step explanation:

0.16 liters in terms of mililiters is equal to 160 ml

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

Given here: 0.16 liters

Now we know 1 liter= 1000 ml

Thus 0.16 liter would be equal to 0.16×1000=160 ml

Hence, 0.16 liters in terms of mililiters is equal to 160 ml

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.

Step-by-step explanation:

Slope intercept form

Answer:

[tex] \frac{5}{2} [/tex]

Step-by-step explanation:

The formula for slope is (y₂-y₁)/(x₂-x₁)

Which means the (y) from the Second ordered pair subtract (y) from the 1st ordered pair, then divide by (x) from the second ordered pair, minus the (x) from the first.

So (3-(-2))/(3-1)

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

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:

Answer: that equals 9

Step-by-step explanation:

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:

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:

with what

Step-by-step explanation:

Answer:

We know that C is the total number of cans in a complete case.

Victoria counts:

16 full cases, so in those we have: 16*C cans.

4 cases with 5 missing cans, so in those we have:

Then if each case has C cans, the cases that are missing 5 cans have:

C - 5 cans.

Then in those four cases we have a total of: 4*(C - 5) cans.

And Victoria knows that there are 220 cans, then we have that:

16*C + 4*(C - 5) = 220

16*C + 4*C - 20 = 220

16*C + 4*C = 220 + 20 = 240

20*C = 240

C = 240/20 = 12

Then each case has 12 cans.

Then the number of cans in the cases with missing cans is:

12 cans - 5 cans = 7 cans.

16c + 4(c-5) = 220

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
