Step-by-step explanation:

[tex]56 = 2n + 99[/tex]

Collect like terms and simplify

[tex]56 - 99 = 2n \\ - 43 = 2n[/tex]

Divide both sides of the equation by 2

[tex] \frac{ - 43}{2} = \frac{2n}{2} [/tex]

Simplify

[tex]n = - \frac{43}{2} = - 21 \frac{1}{2} [/tex]

Answer: $9.60

Step-by-step explanation:

First, we need to calculate the discount given on the pizza. This will be:

= 40% × $16.

= 40/100 × $16

= 0.4 × $16

= $6.40

Then the new price will be gotten by subtracting the amount given off from the original price. This Will be:

= $16 - $6.40.

= $9.60

The new price is $9.60

Step-by-step explanation:

The value of the account will reach to $1,830 in 15 years.

Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.

Given that, Mackenzie invested $770 in an account paying an interest rate of 6.1% compounded continuously after a certain period of time the mount becomes $1830

We know that,

[tex]A = P(1+r)^n[/tex]

Where, A = amount, P = principal, r = rate and n = time.

1830 = 770(1+0.061)ⁿ

1830 / 770 = (1.061)ⁿ

2.37 =  (1.061)ⁿ

Taking log both side,

log(2.37) = n log(1.061)

n = log(2.37) / log(1.061)

n = 14.57 ≈ 15

Hence, the value of the account will reach to $1,830 in 15 years.

Answer:

A ; g(x) = (1/2 x)^2

Step-by-step explanation:

Here, we want to get g(x)

we have a point on the curve g(x)

The point is represented by (2,1)

What this mean here is that, when x = 2, y = 1

Looking at the first option;

Substitute 1 for y and 2 for x

1 = (1/2 * 2)^2

1 = 1

This means this is our answer

The equation for g(x) is;

g(x) = (1/2 x)^2

Step-by-step explanation:

the nice thing about triangle is that the smallest angle is always opposite the smallest side, etc. also, we can get the remaining angle because we have 2 angles already and there are always 180 degrees in a triangle.

50+ 63= 113

180-113 =67

so, 50 is the smallest angle and thus the side opposite of it is the smallest. next is side bc because 63 is the next biggest angle measure. lastly, side ac is the largest because it's opposite of the largest angle measure

A graph is a way to represent a lot of data in a visual format. The number of games in the category 51-57 are 3.

A graph is a way to represent a lot of data in such a visual format that it is easy for the user to understand the complete information in one go. Usually, the line of the graph is a function that follows the graph.

The categories and the data points can be arranged as following,

51 - 57 = 51, 56, 55

58 - 64 = 63, 59, 60, 64

65 – 71 = 70, 67

72 or more = 75

Hence, the number of games in the category 51-57 are 3.

Answer:

[tex]f^{-1}(x)=\frac{1}{8}(x-4)^{3}[/tex]

Step-by-step explanation:

Given function is,

f(x) = [tex]\sqrt[3]{8x}+4[/tex]

To find the inverse of this function,

Rewrite the function as a equation,

y = [tex]\sqrt[3]{8x}+4[/tex]

Interchange x by y and y by x,

x = [tex]\sqrt[3]{8y}+4[/tex]

Now solve this equation for y,

x - 4 = [tex]\sqrt[3]{8y}[/tex]

(x - 4)³ = [tex](\sqrt[3]{8y})^3[/tex]

(x - 4)³ = 8y

y = [tex]\frac{1}{8}(x-4)^{3}[/tex]

Now convert the equation into function,

[tex]f^{-1}(x)=\frac{1}{8}(x-4)^{3}[/tex]

Step-by-step explanation:

According to the problem, calculation of given data are as follows,

Volume of cylindrical vase = [tex]63cm^{3}[/tex]

As, Cone has same height and radius as cylinder, than we can calculate volume of cone by using following formula,

Volume of cone = [tex]\frac{1}{3}[/tex] × Volume of cylindrical vase

By putting the value, we get

Volume of cone = [tex]\frac{1}{3}[/tex] × 63

Volume of cone = [tex]21cm^{3}[/tex]

PLEASE MARK ME AS BRAINLIEST....

Answer:

m = 2600

Step-by-step explanation:

0.12m = 78 + 0.09m

0.12m - 0.09m = 78 + 0.09m - 0.09m

0.03m = 78

m = 2600

Make sure to double check!

2600 x 0.12 = 78 + 0.09 x 2600

312 = 78 + 234

312 = 312

Answer:

(Assuming the . means its a decimal...)

Step-by-step explanation:

Rewrite equation

0.12m = 78 + 0.09m

Multiply each side by 100

12m=7800 + 9m

Subtract 9m on both sides

12m-9m=7800+9m-9m

3m=7800

Divide both sides by 3

m = 2600

Answer:

a.  rate to empty the tank = - 2/3 gal/min

b,  7.5 min to empty the tank

c.  4.5 min.

Step-by-step explanation:

I use the formula that the work done = rate of work times the time working = W = rt

The work in this problem is emptying the tank.  

a.  The rate to empty the tank is -2 gal/3 min or - 2/3 gal/min

b.   5/(2/3) = 15/2 = 7.5 min to empty the tank

c.    Since 3 gal. had already drained, 3/(2/3) = 9/2 = 4.5 min.

[tex]M = \frac{3}{4}[/tex] --- Minor repairs

Required

The parts that are not good enough but only needs minor repairs

To do this, we simply multiply M by N

[tex]Parts = M * N[/tex]

[tex]Parts = \frac{3}{4} * \frac{1}{6}[/tex]

Divide by 3/3

[tex]Parts = \frac{1}{4} * \frac{1}{2}[/tex]
