John has a large number of pennies, dimes, and quarters. How many ways can he make $1.00out of his coins? Note that order doesn’t matter.

Answer:

20&22

Step-by-step explanation:

let the numbers be X and X+2.

By question, X×(X+2)=440

or, X^2+2X=440

or, X^2+2X-440=0

or, X^2+(22-20)X-440=0

or, X^2+22X-20X-440=0

or, X(X+22)-20(X+22)=0

or, (X+22)(X-20)=0

Either,X-20=0 Or, X+22=0

•°•X=20(true) •°• X=-22(false)

•°•X=20

•°•X+2=20+2=22

•°• The two consecutive even numbers are 20 and 22.

Answer: y=-4x+1

Step-by-step explanation:

The slope-intercept form of a line is y=mx+b. Therefore, y needs to be on one side of the equation, and the x term and constant need to be on the other. Rearrange the equation to make this true:

4x+y=1

(4x+y)-4x=1-4x

y=1-4x

y=-4x+1

Answer:

48

Step-by-step explanation:

Answer:

4³×5² or 4³5²

Step-by-step explanation:

This is because there are three consecutive 4s, so you have to put the 4 into exponential form 3 times. So the exponential form for the 4s will be 4³. There are also 2 consecutive 5s so you have to include 2 in the exponential form. So, the exponential form of the 5s is 5². Now you have to somehow multiply them together. You could do this by putting a multiplication sign, (4³×5²) or you could bunch them together and it will mean the same thing (4³5²).

Hope this helps :)

Step-by-step explanation:

2x⁴ = 9x²

2x⁴ - 9x² = 0

x²(2x² - 9) = 0

Either x² = 0 or 2x² - 9 = 0.

When x² = 0, x = 0.

When 2x² - 9 = 0, x² = 9/2, x = ± 3/√2.

Hence the solutions are

x = 0, x = 3/√2 and x = -3/√2.

Answer:

1. C) 3

2. D) -1

3. D) 7^2 - 8*2 - 16

4. B) 75

5. B) 6^2 + (2 - 8)*sqrt(81)

Step-by-step explanation:

1. (10 - (6-4)^2)/2

= (10 - 2^2)/2

= (10 - 4)/2

= 6/2

= 3

2. PEMDAS states that Multiplication is before Subtraction

8 - (5^2-7)/2

= 8 - (25-7)/2

= 8 - 18/2

= 8 - 9

= -1

3. D) 7^2 - (8*2) - 16

= 49 - 16 - 16

= 49 - 32

= 17

4. 3(2 + 3)^2

= 3(5)^2

= 3(25)

= 75

5. 6^2 + (2 - 8)*sqrt(81)

= 36 + (-6*9)

= 36 - 54

= -18

Answer:

137

Step-by-step explanation:

The coordinates are  (-1, 10).

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions. Since it is just moving of the shape from one place to other, there is no change in the shape.

Translation is one of the transformations in math. When a shape has been transformed, the original shape is called the preimage and the vertices are usually labeled using uppercase letters (Example: ABCD). The translated shape is called the image and the vertices are labeled using uppercase letters with a “prime” next to each (Example: A′B′C′D′, and is pronounced “A-prime, B-prime, C-prime, D-prime”).

Given:

the point is (-8, 3) whose image point is (-5, 2)

The difference between the coordinates of the image and the coordinates of the original is the same for both points.

 X - (-6, 5) = (4, 4) -(-1, -1)

 X = (4, 4) -(-1, -1) +(-6, 5) = (4+1-6, 4+1+5)

 X = (-1, 10)

Hence, the point is (-1, 10)

Find how much it grew:

53 - 20 = 33 inches.

Divide the amount it grew by the original length

33/20 = 1.65

Subtract 1:

1.65 - 1 = 0.65

Multiply by 100 for percent:

0.65 x 100 = 65%

The percent increase is 65%

Step-by-step explanation:

The circumference of a circle is given by

C = pi * d

C = pi * 26

C = 26pi

We can approximate pi = 3.14

C =81.64 inches

or we can approximate pi by using the pi button

C =81.68140899 inches

Using the choices listed and approximating pi as 3

C = 3*26 = 78 inches

Step-by-step explanation:

From the question, we are informed that 28 pieces of candy are put into 2 groups in the ratio is 2 to 5.

The number of pieces of candy that will be in each group will be:

1st group = 2/(2 + 5) × 28

= 2/7 × 28

= 2 × 4

= 8

2nd group = 5/(2 + 5) × 28

= 5/7 × 28

= 5 × 4

= 20

Answer:

Neither

Step-by-step explanation:

Triangles are similar if their angles are the same, and if the sides are changed by a proportional ratio. The angles for FED and ZXY are not the same. Therefore, they are not similar

Answer:

D. Neither

Step-by-step explanation:

Similar triangles are scaled versions of each other. Two triangles that are similar will have congruent angles. Hence, to find a triangle that is similarto ABC, the angles of the other triangles will be congruent to the given angles of ABC. As one can see, no other triangle has congruent angles to ABC, and hence the answer is D, neither of the two triangles are similar to ABC.

Answer:

y = -x and 2y = 3x - 10 is the system of equations.

Step-by-step explanation:

Let,

Larger number = x

Smaller number = y

According to given statement;

x + y = 0

y = -x  

And

3x - 2y = 10

Or it can be written as;

2y = 3x - 10

Therefore,

y = -x and 2y = 3x - 10 is the system of equations.
