HELP WHATS IS A multi step equation that has a variable on both side that equals 10

Answer:

False

Step-by-step explanation:

The correct answer is y = -25x + 450

She will have run a total of 2.25 racers in 27 racers

From the question, we have the following parameters that can be used in our solution:

Total number of racers = 27 racers

Number of racers in a run = 12 racers

From the above parameter, we can calculate the total number of racers using the following equation

The total number of racers is calculated as

Total number of racers in the run = Total number of racers/Number of racers in a run

Substitute the known values in the above equation

So, we have the following equation

Total number of racers in the run = 27/12

Evaluate the quotient

Total number of racers in the run = 2.25

Hence, the total number of racers in the run is 2.25 racers

Answer:

x = 154

Step-by-step explanation:

[tex]\frac{x}{11}[/tex] + 16 = 30 ( subtract 16 from both sides )

[tex]\frac{x}{11}[/tex] = 14 ( multiply both sides by 11 to clear the fraction )

x = 11 × 14 = 154

Answer:

x = 154

Step-by-step explanation:

Given equation,

→ (x/11) + 16 = 30

Now the value of x will be,

→ (x/11) + 16 = 30

→ x/11 = 30 - 16

→ x = 14 × 11

→ [ x = 154 ]

Hence, value of x is 154.

The measure of angle 4 is 125° for the given triangle.

According to the question,

We have the following information:

A figure is given of triangle and its exterior angles.

m∠1 = 70°

Now, the two sides (with line on them) of the triangle are equal. So, it means that it is an isosceles triangle.

We know that sum of three angles of a triangle is 180°.

Let's take the two equal angles to be x°.

x+x+70 = 180

2x+70 = 180

2x = 180-70

2x = 110

x = 110/2

x = 55°

We know that angles made on a straight line is 180°.

∠4 and angle x will make a straight line.

∠4 = 180-55

∠4 = 125°

Hence, the correct option is A.

The correct answer option is options A and D

A rectangle is a quadrilateral having opposing sides parallel and four right angles.

At point (x, y) = (10, 100) the area is maximum.

This means that the area of the rectangle is maximum when width is 10m.

If the width of the rectangle is more than 10m, the area reduces or decreases.

Therefore, the statement Greater width relates to greater area as long as the width is more than 10 m is false.

Answer: 18

Step-by-step explanation:

There are no parenthesis or exponents, so you use multiplication first.

6 x 2 = 12

That makes your equation 14 + 12 - 16 + 8

Now you only have adding and subtracting left, which you’ll do from left to right.

14 + 12 = 26

The equation where y is the price of the ticket with the coupon, and x is the original price of the ticket.

y= 0.55 x.

Given:

A movie theater sends out a coupon for 45% off the price of a ticket. Write an equation for the​ situation, where y is the price of the ticket with the​ coupon, and x is the original price of the ticket.

If x is the price of the ticket without the coupon, and the theater offers a discount if you have a coupon, then having a coupon means that the price a person ultimately  pays (y) is  the original price (x) minus a 45% of this price:

y= x -0.45 x

By association: y= (1-0.45) x

and then y= 0.55 x.

The line should be in the first quadrant because the first quadrant allows you to represent a situation in which the dependent variable (y) and the independent variable (x) are both positive. This is the case in this exercise, because both prices, the one without discount (x) and the one with discount (y) are necessary positive (you can not pay a negative price!).

Hence we get the required equation.

The original amount is $92.202.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is primarily used to compare and determine ratios and is represented by the symbol %.

Given:

Total amount = 83.82

rate of increase = 10%

So, the original amount

= 83.82 + 83.82 x 0.1

= 83.82 + 8.382

= $92.202

Hence, the original amount is $92.202.

Answer:

a) 6.2%
b) £13,687

Step-by-step explanation:

a)

To find the rate of interest, we first find the interest itself.
£7965.00 - £7500.00 = £465.00
Using this, we find the rate of interest in percentage as a fraction of the original loan.

(£7500.00 ÷ £465.0) × 100 = 6.2%

Thus, the rate of interest is 6.2%.

b)
Compound interest is found using the formula
[tex]A = P(1 + \frac{r}{100})^{t}[/tex]
Where

A = final amount

P = initial principal balance

r = interest rate

t = number of time periods elapsed

Thus, with an initial balance of £7500, an interest rate of 6.2% and a time period of 10 years, calculated per annum, we can plug the numbers into the formula, giving us

[tex]A = 7500(1 + \frac{6.2}{100})^{10}[/tex]
   [tex]=[/tex] £13,686.94
   ≈ £13,687 (to nearest £1)

Some things to note: number of time periods elapsed mean the amount of times it is compounded; if the question says compounded quarterly for 3 years, t = 12 as it is compounded 4 times a year for 3 years, giving is 12 time periods. This also applies to monthly, bi-weekly etc.

At that particular critical point, the second derivative needs to be negative in order to obtain the dimensions of the cylinder with the maximum volume. The values of the function that contain both variables are then substituted to obtain the dimensions.

A right circular cone with a height of 2.5 and a base radius of 7.5 inscribes the given cylinder.

Assume that h is the height and r is the radius of the cylinder. Using triangles that are similar, express h in terms of r as follows:

2.5/7.5 = 2.5-h/r

2.5r = 18.75 x 7.5 x 2.5 h = 2.5 x 1/3r

V= πr²h is the formula for the cylinder's volume.

As a result, only write the volume in terms of r.

V= r2h V= r2(2.5-1/3r)

V= 2.5πr² - 1/3πr³

As a result, the cylinder must have dimensions of r=5 and h=0.83.
