Answer:

the answer is c 29.04 meters squared

Step-by-step explanation:

first you multiply 2.2 by 2.2 to get 4.84 then you multiply that by 6 to account for all of the faces

Answer and Step-by-step explanation:

A reflection of shape I across the y-axis followed by a 90° clockwise rotation about the origin

The sequence of transformations stated is correct.

First, the shape will be reflected across the y-axis. So essentially, make all the x-value points the opposite (turn positive values to negative, and negative values to positive; in this case, turn the positive x-values to negative x-values.)

Then, you rotate the figure 90 degrees counterclockwise (going up, not to the right on the graph, like how the minute and hour hand move around the clock.) The points will line up with shape II.

Answer:

Step-by-step explanation:

B is correct as 1.1 = 110%

C is correct as adding (0.1 multiply original price) = 1.1 = 110%

E is correct as dividing original price by 0.1 then multiplying by 11 = 1.1 = 110%

Correct Answer: B, C

Choice A only finds the amount that is increased by, not the new price

Choice D is if the original price is discounted by 10%

The second part of Choice E does not make sense

Basically, here is how you find the new price:

Let the original price be x.

New Price = x * (1 + 10%) = x * (1 + 0.1) = x * 1.1

Answer:

Fraction: 6/10 Decimal: 0.6

Step-by-step explanation:

There are 100 blocks and 60 are shaded. If you take the last zero off of both numbers you get 6 and 10. The larger number is the denominator because the denominator is always larger otherwise its an improper fraction. That leaves the 6 as the numerator so there is your fraction. Next, just convert it into a decimal as you're done!

Step-by-step explanation:

Answer:

(a)19.5 per hour

(b)Kaylee earns more per hour.

Step-by-step explanation:

a.) To find the unit rate/hourly rate :

39÷2=19.5 per hour.

b.)Kaylee eanrs more considering that Joey earns 16.50$ per hour as opposed to 19.50$ per hour.

Answer:

(a) Kaylee earns $19.50 per hour.

(b) Kaylee earns more money per hour than Joey.

Step-by-step explanation:

x = # of hrs. worked

y = amount of money earned

Joey:

y = 16.50x

Kaylee:

Time (h) 2, 5, 8, 10

Money earned ($) 39, 97.50, 156, 195

y = mx + b; Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

We will be using: (2,39) and (8,156) to find the slope of this table.

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{156-39}{8-2} \\\\m=\frac{117}{6} \\\\m=19.5[/tex]

y = mx + b

y = 19.5x + b

I will be using (2, 39) to find the value of b

(2, 39)

y = 19.5x + b

39 = 19.5(2) + b

39 = 39 + b

-39  -39

0 = b

y = 19.5x + b ==> y = 17.7x + 0 =  OR  y = 19.5x (since the value of b is 0)

(a) The question wants us to find out how money Kaylee earns per hour. Recall that x = # of hrs. worked and y = amount of money earned.

y = 19.5x

She earns $19.50 per hour.

(b)

Joey: y = 16.50x (earns $16.50 per hour)

Kaylee: y = 19.5x (earns $19.50 per hour)

As you can see, Kaylee earns more money per hour than Joey.

Answer:

12 guests(13 including yourself), 78 ounces of dough, and 52 ounces of sauce.

Step-by-step explanation:

So what you want to do is to first add up the dough and the sauce which is 10. then you want to divide 130 by 10 and you get 13(130/10=13) Now we subtract 1 from 13 and that how many guests you have which is 12. now we time 6 by 13 which is 78(6*13=78) so 78 ounces of dough. Now we time 4 by 13 and we get 52(4*13=52) so 52 ounces of sauce. Now to make sure it's right we need to add 78 and 52 together and we get 130(78+52=130) And that's all

Answer:

10 rides

Step-by-step explanation:

x = number of rides

Option 1 = $55 + $2x

Option 2 = $15 + 6x

Ride #1 - Option 1 = $57 Option 2 = $21

Ride #2- Option 1 = $59 Option 2 = $27

Ride #3-  Option 1 = $61 Option 2 = $33

Ride #4- Option 1 = $63 Option 2 = $39

Ride #5- Option 1 = $65 Option 2 = $45

Ride #6- Option 1 = $67 Option 2 = $51

Ride #7- Option 1 = $69 Option 2 = $57

Ride #8- Option 1 = $71 Option 2 = $63

Ride #9- Option 1 = $73 Option 2 = $69

Option A is correct, (5, 9) is the point not on the graph of the function y = x - 4.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The given function is y=x-4.

Let su check all the given points whether they are point of the given graph or not.

The point (5, 9) is not on the graph of the function  y = x - 4

Because when x = 5, y = 1, not 9.

The point (234, 230) is  on the graph of the function  y = x - 4

Because when x = 234, y =230

The point (7, 3) is  on the graph of the function  y = x - 4

Because when x = 7, y =3

The point (12, 8) is  on the graph of the function  y = x - 4

Because when x = 12, y =8

Hence, (5, 9) is the point not on the graph of the function y = x - 4.

To find the number of inches, times the number of feet by the unit rate, 12 inches per foot

If you wanted to figure out how many inches are in 3 feet, you multiply 3 with 12, getting you 36. So, there are 36 inches in 3 feet

Answer: y = 1x -3

The 1 is not necessary so

y= x - 3

Step-by-step explanation:

(y- y1) = m(x -x1). First

Substitute y and x-values from the given coordinates and solve for x.

7-(-1)=m(10-2)

8 = m(8) 8/8=1 T

m= 1 The slope, m is 1

Then substitute values of y and x from either given coordinate into the equation and solve for b, the y-intercept.

y=mx+b

-1= 1(2)+b

-1=2+b subtract 2 from both sides.

-1-2 = b

-3 = b

OR

7= 10 + b

-10 +7 = b

-3 = b

Finally, write the equation with the values for m and b

y = 1x +(-3) Simplify & Rewrite

y= x - 3

Answer:

7 over 36

Step-by-step explanation:

You just multiply side by side

Answer:

[tex]\frac{7}{36}[/tex]  7/36

Step-by-step explanation:

in order to find the product of 2 fractions you need to first make sure that they both have common denominators. in order to find the common denominators you need to find the LCM (lowest common multiple) of the two denominators

so 7/9 and 1/4 the lcm of 9 and 4 is 36

[tex]\frac{7}{9}[/tex] x 4 = [tex]\frac{28}{36}[/tex]     [tex]\frac{1}{4}[/tex] x 9 = [tex]\frac{9}{36}[/tex]    28/36 x 9/36 = 28 x 9 = 252/36 = 7 /36

50 balloons in total

now just put 18/50 because you are looking for the probability of yellow balloons  

Answer:

C. 9/25

Step-by-step explanation:

Total number of drawings of balloons = 15 + 18 + 9 + 8 = 50
