Which ratio is equivalent to 2:3? A 8:12 B 9:10 C 10:9 D 12:8​

Answer:

9 inches wide

Step-by-step explanation:

What we know:

Cindy has a 3-inch by 4-inch picture.

She wants to enlarge that picture so the length is 12 inches.

It's 4 inches long in the original, and 12 inches in the scale.

Divide 12 by 4 to get a scale factor of 3.

Multiply 3 by 3 (essentially 3^2) to get 9 inches as the width.

Answer:

  A, C

Step-by-step explanation:

The quadratic formula can be used to solve quadratic (2nd-degree) equations. The degree of the equation is the largest exponent of the variable.

The degrees of these equations are ...

  A. 2

  B. 3

  C. 2

  D. 3

Equations A and C are quadratic, so can be solved using the quadratic formula.

The answer is 13 by using Pythagorean theorem.

Answer:

7 1/2

Step-by-step explanation:

8x = 12

divide both sides by 8 to get x alone

this proves that x = 1.5

because 12/8 = 1.5

then

2y + 10 = 22

subtract 10 from both sides : 2y = 12

then divide both sides by 2 to get y alone

y = 6

then

add x and y together : 6 + 1.5 = 7.7 or 7 1/2

Answer:

x < 15

Step-by-step explanation:

we want to isolate x, so we get rid of the 3, that is being divided by 2x, we take it to the other side to multiply.

2x < 10 x 3

2x < 30

we move the 2 that is multiplying x to the other side, since it was multiplying, we make inverse operations and now the 2 will divide 30

x < 30 ÷ 2

x < 15

Answer:

x=15 or false

Step-by-step explanation:

In order to find x you have to get the x by itself. To do this you multiply 3 on both sides this gives you 2x<30. Then you divide by 2, this gives you x=15. Then in order to find whether or not the inequality is true you have to plug x back in. 2(15)/3<10 is equal to 30/3=10 which leads to 10<10, which is false.

Answer:

[tex]\frac{(a*a)(b*b*b)}{c*d}[/tex]

Step-by-step explanation:

[tex]\frac{a^{2} * b^{3}}{cd}[/tex]

A number to an exponent is the number times itself. A number to the "n"th power would be that number times itself "n" times.

This means that the fraction above could also be expressed as;

[tex]\frac{(a*a)(b*b*b)}{c*d}[/tex]

If these parameters, "a", "b", "c", and "d" are given a value, then one can solve this equation.

Answer:

Simplify the equation as closely as possible to the form of y = mx + b. Check to see if your equation has exponents. If it has exponents, it is nonlinear (exponential). If your equation has no exponents, it is linear.

Answer:

10i

Step-by-step explanation:

The square root of negative 100 is not equal to 10. If 10 was the square root of negative 100, then 10 squared would be equal to negative 100. But in fact, 10 squared is 10*10, which is obviously (positive) 100, not negative 100.

To determine the actual value of the square root of negative 100, we can proceed as follows:

Let s be the square root of negative 100.

Then s^2 = -100.

So s^2 = 100×(-1) = (10^2)×(i^2) =10×10×i×i = 10×i×10×i =(10i)^2.

So s = 10i.

So the square root of negative 100 is equal to 10i.

Note that the square of -10i is also equal to negative 100. 10i is the principle square root of negative 100.

Answer:

10i

Step-by-step explanation:

Since, it's a negative square root you have to use imaginary numbers to make it solvable. Hope this helps! :)

The function f(x) = -3 |x+2| represent the graph A. The correct option is A.

A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The function f(x) = -3 |x+2| is an absolute function. On plotting the graph of the function we will get the graph at (-2,0) coordinate and cut the y axis at ( 0,-6 ) coordinate. The graph is attached with the answer below.

Therefore, the function f(x) = -3 |x+2| represent the graph A. The correct option is A.

Answer: 4/5 (B)

Step-by-step explanation:

The ratio is 5/9 represents the number of students who prefer soccer to the total number of students in Arturo’s class

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

To determine the ratio represents the number of students who prefer soccer to the total number of students in Arturo’s class

Here the number of students who prefer soccer = 20

The total number of students in Arturo’s class = 20 + 16 = 36

According to the given situation, the required ratio is written as:

The required ratio = students who prefer soccer / total number of students

The required ratio = 20 / 36

Convert the above fraction into the simplest form

The required ratio = 5/9

Therefore, the ratio is 5/9 represents the number of students who prefer soccer to the total number of students in Arturo’s class

Answer:

Number of men's shoes = x = 9 shoes

Number of women's shoes = y = 27 shoes

Step-by-step explanation:

A shoe store pays 1980$ a month for rent. The average profit on each pair of men's shoes is $25, and the average profit on each pair of wemons shoes is $65. .How many pairs of shoes of each type of shoe must the store sell each month to pay the rent?

Number of men's shoes = x

Number of women's shoes = y

The system of equations is given as:

$25 × x + $65 × y = $1980

25x + 36y = $1980..... Equation 1

They usually sell 3times as many pairs of wemons shoes as men's

y = 3x

25x + 65y = $1980..... Equation 1

25x + 65(3x) = 1980

25x + 195x = 1980

220x = 1980

x = 1980/220

x = 9 shoes

y = 3x

y = 3(9)

y = 27 shoes

Number of men's shoes = x = 9 shoes

Number of women's shoes = y = 27 shoes

Answer:

The total volume of this 3D Figure is 944.

Step-by-step explanation:

The volume of:

1. The above figure is 400.

2. The bottom figure is 544.

3. Add the total volume of those 2 figures (400+544).

4. You have found the final answer!

Answer:

So the first part of this shape is 400 ft and the secound part of this shape is 544 ft. Hence, since want the whole shape volume your answer would be and always will be 944 ft.

Step-by-step explanation:

since i'm pretty good at math I well tell you how I got this answer in this qustion I seen that this figure is 3-dimensional meaning that we have height,length, and width ( there is two more and were not going to talk about it ) prove we got to time not 2 but 3 times and since this figure has 2 part we would need to brake it into and mutlply both parts (sepertly) to get the answer right so for the first part (or what on the top).

1st part

since the height is 5 ft. that is the first part of our equation,I see that the width must be 10 ft., which well be the second part of our equation, and i see the length is  8 ft so our equation is , 8x10x5 witch mean the first part of the figure is 400 ft

2nd part

since the height is 4 ft. this mean we have the first part of our equation,the width is 8 ft so that the second part of our equation,and I see the length is 17 ft., means this equation is 4x8x17 so this part of the figure is 544 ft.

The whole figure

So with are info from the first and second part of our equation we can now add both parts of the figures  means if we add both of them the answer would be 944 ft.

if you don't other stand  here a tip:In geometry, a three-dimensional shape can be defined as a solid figure or an object or shape that has three dimensions – length, width and height. Unlike two-dimensional shapes, three-dimensional shapes have thickness or depth.
