Step-by-step explanation:

Think about it like this. A full rotation is a 360 degree rotation. Each turn is a 90 degree turn. So, go the other way and count how many turns you do. 270!

Answer:

The scale factor is 1/3

Step-by-step explanation:

Here, we want to get the scale factor used in dilating the original segment

As we can see;

(9,3) turned to (3,1)

looking at this , we can see that both coordinate values were divided by 3

So what this mean is that the particular scale factor used is reduction by 1/3

This is the case with the other point as (-6,-9) turned to (-2,-3)

Step-by-step explanation:

A function does not have any repeating values for a given x-value. According to the values of the table, there aren't multiple y-values for a given x-value. Therefore, the table represents a function.

Answer:

48,58

Step-by-step explanation:

Let The speed of the west bound train be x

Let the east bound train be x+10

The speeds can be calculated as follows

2(2x+10)= 232

4x + 40= 232

4x= 232-40

4x= 192

x= 192/4

= 48

Hence the speedof the west bound train is 48

The speed of the east bound train is 48+10

= 58

Answer:

156.25

Step-by-step explanation:

8x2 (2 years) = 16. 2500 / 16 = 156.25

y = -2x + 3

in the equation y = mx + b, the m represents the slope and b represents the y-intercept

remember that slope is rise over run:

   starting from the point (1, 1) you rise 2 up and go over left 1 to reach the second point shown (0, 3).

   add a negative sign to show the negative downward slope, and the m in the equation would be -2

the y-intercept is just where the line hits the y-axis, or when the x in the ordered pair is 0. In this graph, one of the points given is (0, 3) so 3 is the y intercept

just plug all that into y = mx + b

m, the slope, is -2 and b, the y- intercept, is 3.

y = -2x + 3 is your answer

Step-by-step explanation:

By question ,

=> cot∅ = 2/11

=> cot∅ = 2x/11x = b/p

Pyhthagoras Theorem :-

=> h² = (2x)² + (11x)²

=> h² = 4x² + 121x²

=> h² = 125x²

=> h = √ 25 × 5 x

=> h = 5√5 x

(1/5)n - 4 = 16

One fifth of a number less 4 is 16

Answer:

Step-by-step explanation:

a:b = 8:5

a = 8x, b= 5x

a+b = 91

13x = 91

x = 7

a=8x = 56

b = 5x = 35

The larger number is 56

Answer:

y=4x-14

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(10-2)/(6-4)

m=8/2

m=4

y-y1=m(x-x1)

y-2=4(x-4)

y=4x-16+2

y=4x-14

Answer:

The investment will be worth $450 after 25.255 years which is about 25 years and 3 months.

Step-by-step explanation:

You have to use the following formula to calculate the number of years:

t=ln(A/P) / n(ln(1 + r/n)), where:

t=time in years

A=Accrued amount=450

P=Principal amount=100

n=number of compounding periods per time period=4

r=interest rate=0.06

Now, you can replace the values in the formula:

t=ln(450/100)/4(ln(1+(0.06/4)))

t=ln(4.5)/4(ln(1.015))

t=1.50/0.059

t=25.255

According to this, the answer is that the investment will be worth $450 after 25.255 years which is about 25 years and 3 months.

Step-by-step explanation:

Answer:

1200 square inches

Step-by-step explanation:

First find area of rectangle which is length x width

20 x 30 = 600

then to find area of the two right triangles multiply the legs then divide by 2

20 x 30 = 600

600/2 = 300

since there is 2 multiply 300 by 2

600

then add everything together

600+600 = 1200

Matrices is an array of numbers, symbols and expressions arranged in rows and columns. Matrices can be used to solve system of equations. Many mathematical operations can be done on matrices such as addition, subtraction, multiplication, scalar multiplication and so on.

Addition and subtraction of two matrices can be done if they have the same dimensions.  This is done by simply adding or subtracting the corresponding entries in matrices.

Reflection

Step-by-step explanation:

Even if it's not over the x or y axis it's still a reflection over a line.

Answer:

y = (x + 9)² -93

vertex: (-9, -93)

Step-by-step explanation:

x² + 18x = 12

x² + 18x + 81 = 12 + 81

(x+9)² = 93

y = (x + 9)² -93

vertex: (-9, -93)

We would expect that 4 of the next 9 children to enroll will be elementary school students.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

If 8 out of the last 18 children to enroll at the daycare center were elementary school students,

We can find the fraction of elementary school students in that group by dividing the number of elementary school students by the total number of children:

= 8/18

= 4/9

This means that 4 out of every 9 children enrolled were elementary school students.

If we want to predict how many of the next 9 children to enroll will be elementary school students,

We can use this ratio:

4/9 of 9 children

= (4/9) x 9

= 4

Therefore,

We would expect that 4 of the next 9 children to enroll will be elementary school students.

Answer:

Number of hours she worked so far = 15 hours

Step-by-step explanation:

Total hours scheduled to work this week = 20 hours

Percentage of Hours worked so far = 75%

How many hours has she worked so far this week?

Number of hours she worked so far = 75% of 20 hours

= 75/100 * 20

= 0.75 * 20

= 15

Number of hours she worked so far = 15 hours
