write two ratios that are equvilent to 3:11
Answer:
6:22, 9:33
Step-by-step explanation:
When writing equivalent ratios, you use two of the numbers from the original ratio and multiply them evenly to get an equivalent ratio.
[tex]\mathrm{p:q~or~\frac{p}{q} = \frac{x(p)}{x(q)}}\\\mathrm{\frac{6 \times 2}{11 \times 2} = 6:22}\\\mathrm{\frac{6 \times 3}{11 \times 3} = 9:33}[/tex]
Answer:
6:22 and 9:33
Step-by-step explanation:
Answer: 6:22 and 9:33
Think of the ratio like a fraction, one way to find an equivalent ratio is to simplify the current ratio. But in this case, we are unable because we can divide 3 by 3 to get one, but not 11 by 3.
3 divided by 3 = 1
11 divided by 3 = does not evenly divide
Another way is to multiply both numbers by the same number.
3 times 2 = 6
11 times 2 = 22
And we can just keep doing the same with different numbers.
3 times 3 = 9
11 times 3 = 33

You get your hair cut at a shop that charges $30. They offer you a deal: If you prepay $150 for five haircuts, they'll give you a punch card that entitles you to a sixth haircut free. The punch cared expires in one year. Is this a good deal?
yes, it is a good deal as long as you use the card before a year.
Is this a good deal?Let's see how much you will save if you pay the $150.
If you want 6 hair cuts, you need to pay $30 6 times, so the total cost will be:
C = $30*6 = $180
If instead, you prepay $150, then you get the 6 cuts only for $150, saving a total of $30 (but the downpayment is 5 times larger than in the other case), but only if you plan to use the punch card for the other cut in the year, if you don't then this option does not make sense.
So, yes, it is a good deal as long as you use the card before a year.

The statement about the function y = −14x − 2 that is true is that A. As the value of x increases, the value of y increases. B.
How to illustrate the information?It should be noted that the information is to get the dtatement about the function y = −14x − 2 that is true.
y = −14x − 2
Let's use x = 1
y = −14x − 2
y = -14(1) - 2 = -16
When x = 2, y = −14x − 2.
y = -14(2) - 2 = -40
It shows that as x increases, y will also increase.

A rectangular box with top WXYZ and base ABCD has AB=6 cm, BC=8 cm and WA=3 cm
Calculate:
a) the length of AC
b) the angle between WC and AC
The length of the AC is: 10cm
Rectangle length : since, a rectangle is a 2-D shape, it is characterized by two dimensions, length, and width. Length is the longer side of the rectangle and width is the shorter side.
So we have to find the length of AC in which AB=6cm and BC=8cm
Step by step explanation :
AC2= 6²+8²= 100
So AC= 10cm
The angle between WC and AC is 16.7°
Angle: .The space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet
So we have to find the angle between WC and AC , so here is a step by step solution:

The right response is Perimeter, x - 2y = 9.
The parameters listed in the question are:
A rectangle's perimeter is equal to 6 x – 2, its length to 2 x + 4, and its width to 2 y + 4.
The perimeter is calculated using the following formula: 2(L) + 2 (W)
6x - 2 = 2(2x + 4) + 2(2y +4) = 4x + 8 + 4y + 8
The result is: x - 2y = 9 and 2x - 4y = 18.
Consequently, the right response is x - 2y = 9.

SportCo manufactures basketballs. The fixed expenses are $46,270 and the variable expenses are $6.50 per basketball produced. How many basketballs did they produce if their expenses total $87,870?
SportCo manufactured 6400 basketballs
SportCo manufacturers fixed expenses for producing basketballs = $46,270
Variable expense incurred per basketball produced = $6.50
Total expenses incurred by SportCo for producing basketballs= $87,870
Fixed costs are costs that remain constant regardless of whether more or fewer goods or services are produced or sold.
An expense for the company that varies according to how much is produced or sold is called a variable cost. Depending on a company's production or sales volume, variable costs grow or fall. They climb as production rises and reduce as production declines.
Let x be the number of basketballs produced by the manufacturer SportCo.
Formulating the equation we get:
Fixed cost + Variable cost*Number of basketballs produced = Total expenses incurred by the manufacturer
46270 + 6.5(x) = 87870
6.5(x) = 41600
x = 6400

The perimeter of the polygon is 232 units
Perimeter of a polygonFrom the question, we are to determine the perimeter of the regular polygon
From the diagram,
One of the polygon's side length is (4/3)x - 1/3
and another side length is x + 7
Since the figure is a regular polygon, we can write that
(4/3)x - 1/3 = x + 7
Now, solve for x
(4/3)x - 1/3 = x + 7
Multiply through by 3
4x - 1 = 3x + 21
4x - 3x = 21 + 1
x = 22
One of the polygon's side length is x + 7
∴ One side length = 22 + 7
One side length = 29
Since the polygon has 8 sides,
The perimeter of the polygon will be
8 × 29
= 232 units
Hence, the perimeter of the polygon is 232 units
