Raven plans to increase the price of each item in her store by 10%. Which the following sets of steps could Raven use to find the new price of each item. Place a checkmark in the box next to each correct set of steps.
A. Multiply the price of each item by 10%
B. Multiply the price of each item by 1.1
C. For each item, multiply its price by 0.1 and then add that product to the original price of the item.
D. Multiply the price of each item by 0.9
E. For each item, divide the price by 10 to find 10% of the item and then multiply that quotient by 11 to find 110% of the origional price.
Answers
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
The distance of planet Mercury from the Sun is approximately 5.8 ⋅ 107 kilometers, and the distance of planet Venus from the Sun is 1.1 ⋅ 108 kilometers. About how many more kilometers is the distance of Venus from the Sun than the distance of Mercury from the Sun?
5.2 ⋅ 107 kilometers
4.7 ⋅ 108 kilometers
5.2 ⋅ 108 kilometers
5.7 ⋅ 109 kilometers
I NEED THIS ANSWER ASAP
Answers
Answer:
5.2
Step-by-step explanation:
distance(Mercury, Sun) = 5.8 x 10^7
distance(Venus, Sun) = 1.1 x 10^8
distance(Venus, Mars) = 1.1 x 10^8 - 5.8 x 10^7
The subtraction is a little easier if you borrow a power of 10 from the 10^8, multiplying 1.1 by 10.
simply subtract 5.8 from 11.0.
This gives us a result of 5.2 x 10^7.

Which point is not on the graph of the function y = x - 4?

Answers
(5,9)

9=5-4
9 = 1 <— wrong
Point (5,9) will not be on the graph because when you substitute the point into the equation, 9 will never equal 1.
Option A is correct, (5, 9) is the point not on the graph of the function y = x - 4.
What is Graph?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.

(2, -1) and (10, 7).
y = _x+ _
Answers
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

Give the amount as a fraction and as a decimal.

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.

Which sequences of transformations confirm the congruence of shape II and shape I?
a reflection of shape I across the x-axis followed by a 90° clockwise rotation about the origin
Answers
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.

The equation y = 16.50x describes the amount of money Joey earns, where x is the number of hours he works and y is the amount of money he earns.
The table shows the amount of money Kaylee earns for different numbers of hours worked.
Kaylee’s Earnings
Time (h) 2 5 8 10
Money earned ($) 39 97.50 156 195
(a) How much money does Kaylee earn per hour? Show your work.
(b) Who earns more per hour? Justify your answer.
Answers
Answer:
(a)19.5 per hour
(b)Kaylee earns more per hour.
Step-by-step explanation:
a.) To find the unit rate/hourly rate :
39÷2=19.5 per hour.
b.)Kaylee eanrs more considering that Joey earns 16.50$ 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.
