Answer 1

Answer:

2 adult tickets

Step-by-step explanation:

we have two relations

[tex]a + c = 5[/tex]

[tex]9a + 4c = 30[/tex]

first rearrange the top equality for one of the variables

[tex]a = 5 - c[/tex]

now substitute into the second equation

[tex]9(5 - c) + 4c = 30[/tex]

perform the distribution and combine like terms

[tex]45 - 9c + 4c = 30[/tex]

[tex]45 - 5c = 30[/tex]

[tex] - 5c = - 15[/tex]

[tex]c = 3[/tex]

place this 3 into our first equation and solve for a

[tex]a + (3) = 5[/tex]

[tex]a = 2[/tex]

Find the x-intercept(s) and the coordinates of the vertex for the parabola y=x + 2x-15. If there is more than one x-intercept, separate them with commas,​

Answers

Step-by-step explanation:

y = x^2 + 2x - 15

To find the x-intercepts, factor out the right side:

y = x^2 + 2x - 15

= (x + 5)(x - 3)

This means that the x-intercepts are at (-5, 0) and (3, 0).

Method 1:

The x-coordinate of the vertex of a parabola is given by the following:

x = -b/2a, where a = 1 and b = 2

= -(2/(2×1))

= -1

Using this value of x gives y = -16

Therefore, the coordinates of the vertex is (-1, -16).

Method 2:

We can find the x-coordinate of the vertex by taking the derivative of y and equating it to zero:

y' = 2x + 2 = 0 ---> x = -1

Using this value of x into our equation, we get y = -16.

Therefore,

vertex: (-1, -16)

Javier made 180 cupcakes. Each cupcake is covered with frosting. • 1/3 of the cupcakes have vanilla frosting. • 1/10 of the cupcakes have lemon frosting. • 2/5 of the cupcakes have chocolate frosting. • the rest have strawberry frosting. How many cupcakes have strawberry frosting

Answers

Answer:

30 strawberry cupcakes

Step-by-step explanation:

180 cupcakes in total

1/3 of 180 - 60 = vanilla

1/10 of 180- 18 = lemon

2/5 of 180 - 72 = chocolate

rest of 180 - 180-(72+18+60) = strawberry

rest of 180 - 180-150 = 30 = strawberry

Add all of them:

60 vanilla

18 lemon

72 chocolate

30 strawberry

---------------------------

180 cupcakes

When Avani goes bowling, her scores are normally distributed with a mean of 145 and a standard deviation of 12. Using the empirical rule, determine the interval that would represent the middle 68% of the scores of all the games that Avani bowls.

Answers

Answer:(133,157)

Step-by-step explanation:

Using the empirical rule, the interval that would represent the middle 68% of the scores of all the games that Avani bowls is (133, 157).

What is Empirical Rule?

Empirical rule is a rule for normally distributed data which defines that almost all the data observed ranges between three standard deviations from the mean.

Here, the scores of Avani is normally distributed.

Mean, μ = 145

Standard Deviation, σ = 12

By the Empirical rule, about 68% of the data falls within one standard deviation.

That is, in the interval μ ± σ.

Interval is (μ - σ, μ + σ) = (145-12, 145+12) = (133, 157)

Hence the interval is (133, 157).

Find the value of x.

Answers

Answer:

(B) 18

Step-by-step explanation:

The shape is fliped but when put to the point where the shapes look the same QP is congruent to DE. Shape DEFG is 2 times bigger than shape PQRS. So all the line measures on PQRS are 2 times smaller than those on DEFG. Meaning x or QP is equal to 18 since 36 divided by 2 is 18.

A book sold 42,000 copies in its first month of release. Suppose this represents 9.6 of the number of copies sold to date. How many copies have been sold to date?

Answers

Answer: 437,500 copies

Step-by-step explanation:

42,000 copies were sold in the first month and this is 9.6% of the total that have been sold till date:

To find the total that have been sold till date, assume the amount to be x.

Expression will be:

9.6%x = 42,000

x = 42,000 / 9.6%

x = 42,000 / 0.096

x = 437,500 copies

437,500 copies have been sold to date.
