Answer:

1. Enlarge, Shrink

2. Smaller

3. Bigger

Step-by-step explanation:

Dilation is something expanding or shrinking, like how your eyes dilate.

Simply think of the scale factor as what you are multiplying the entire figure by. If you are multiplying it by let's say 2, it would double in size, thus getting larger. If you were to multiply it by 1/2, then it would decrease, or shrink, to half its original size.

Answer:

1: enlarge, shrink

2: smaller

3: bigger

[50 pts] Zeke is a cook at Maxine’s Café after school and earns $12.75 per hour. Zeke worked a lot hours this week and charged $17.90 in meals. After paying for meals, Zeke’s earnings were less than $240. Which inequalities can be used to find h, the maximum number of hours that Zeke could have worked this week? (choose 2)


A 240 > 12.75h + 17.90

B 240 > 12.75h – 17.90

C 12.75h – 17.90 < 240

D 12.75h – 17.90 < 240

E 17.90 – 12.75h < 240

Answers

Answer:

240 > 12.75h – 17.9012.75h – 17.90 < 240

Step-by-step explanation:

Zeke's earnings are:

12.75h - 17.90

This amount is less than 240.

This can be shown as:

12.75h - 17.90 < 240 or240 > 12.75h - 17.90

The matching choices are B, C and D (note C and D are given same, must be a typo)

Answer:

C 12.75h – 17.90 < 240

Answers

Answer:

to get which one is the best we have to bring them packages to the same terms

so to do that we have to find what each package offers per month by divided the amount by the number of months

so

160/4= 40

128/4=32

60/2=30

so the best package is

B. package 1

Which of the following represents an equation in standard form for the line that passes through (3, −1) and (−5, −3).

Answers

Answer:

y = ¼x + (-7/4)

Step-by-step explanation:

find the gradient ( M)

M = y2- y1 ÷ x2-x1

M= -3 - (-1)÷(-5)-3 = ¼

the

find C in the equation (y=mx+c)

C = y-mx ( C = -1-¼(3)= -7/4

(use in y and x values provided)

now replace the values you find in the equation (y=Mx+C)

final answer is

y = ¼x+(-7/4)

y = ¼x + (-7/4) is the standard form for the line that passes through (3, −1) and (−5, −3)

What is Slope intercept form?

y=mx=c is the slope intercept form of a line, m is the slope.

We need to find equation of line passing through (3, −1) and (−5, −3)

First we need to calculate slope 'm'.

slope m = y2- y1 / x2-x1

y2=-3, y1=-1, x2=-5, x1=3

m= -3 - (-1)/(-5)-3 = -2/-8=1/4

Equation of line, y=mx+c

find C in the equation (y=mx+c)

C = y-mx

C = -1-1/4(3)= -7/4

now replace the values you find in the equation (y=Mx+C)

y =1/4x-7/4

Hence y =1/4x-7/4 is the equation of line  passes through (3, −1) and (−5, −3).

¿Cuál es el perímetro de un rectángulo, si su diagonal mide 37 m y el ancho mide 12 m ?

Answers

Answer:

94 m

Step-by-step explanation:

Sea L definido como

L = la longitud del rectángulo, en unidades de metros.

Así, según el Teorema de Pitágoras, tenemos que

12 ^ 2 + L ^ 2 = 37 ^ 2

L ^ 2 = 37 ^ 2-12 ^ 2

L ^ 2 = (37 - 12) (37 + 12)

L ^ 2 = 25 * 49, de modo que

L = 5 * 7 = 35.

Por lo tanto, el perímetro = 2L + 2W = 2 (L + W) = 2 (35 + 12) = 2 (47) = 94 m

We have 10 stadiums each holding 105 people.
If each stadium has 8 events each year that’s 80 events per year in total.
So there is 800 events throughout the 10 years (each year holding 80 events).
To find the total number of people that attended the event we multiply the number of people that attended each event by how many events we had in total (105x800=84000)
So, C,D and E apply.

we use

cos^2 x + sin^2 x = 1

cos^2 x = 1 - sin^2 x = ( 1 + sin x) ( 1 - sin x )

therefore

cos ^2 x over 1 - sin x = 1+ sin x

The number of people who can enter in the amusement park is 7.

What is inequality?

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Several buddies want to visit the theme park. They may only spend a total of $280 for parking and entrance. Tickets cost $33.75 per person, including tax, and parking is $19.50.

Let p be the number of people who can enter in the amusement park. Then the inequality is given as,

33.75p + 19.50 ≤ 280

Simplify the inequality, then the value of p is given as,

33.75p + 19.50 ≤ 280

33.75p ≤ 260.50

p ≤ 7.72

Thus, the number of people who can enter in the amusement park is 7.

so I'm not sure how to draw a square with the area of 3 units

Answers

The area of a square is width x height where both the width and height is the same length because a square has the same lengths on all four sides.

So we can say “3 = L x L” where L is any side length of the square

L times L is just simplified to L squared: “3 = L^2”

We can take the square root of both sides to get rid of the L squared. We are left with “the square root of 3 equals L”.
Sqrt(3) = L

And on a calculator the square root of 3 is 1.73205080757.

1.73205080757 = L.

The square is 4 lines in a box each with the length of 1.73205080757 units.

how to find an expression for the perimeter of the rectangle​

Answers

Answer:

Step-by-step explanation:

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.
