Esi says that the value of z when z^2 = 80 does not belong in either of these categories since z must be greater than 8.
What whole number would z be closest to?
(please explain)
Answers
Answer:
9
Step-by-step explanation:
if z=8 then z^2 would be 64, which is not equal to 80
iz z=9 then z^2 would be 81, which is closer to 80 than 64
therefore, 9 is the whole number than z would be closest to

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

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.

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

(12, 8)
Answers
(5,9)
X Y
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.

Use point-slope form, y - y1 = m(x - x1), to find the linear equation of a line that passes through the points
(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

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.

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.

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.

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
Oliver read for 450 minutes this month. His goal is to read for 10% more minutes next month.
If Oliver meets his goal, how many minutes will he read in all during the two months?
Oliver will read __minutes in the 2 months.
Answers
Answer:
495 min
Step-by-step explanation:
Answer:
945 minutes
Step-by-step explanation:
The first step is to find 10% of 450:
[tex]\frac{10*450}{100*1}[/tex]
10 times 450 is 4500 and 100 times 1 is 100
Then 4500 divided by 100 and the answer is 45 minutes.
After that add that 10% of 450 ( 45 ) to 450 to find the minutes he reads in the next month and the answer is 495 minutes.
So because you want the time he read in the two months add 450 and 495 tp get:
450 + 495 = 945
So Oliver read for 945 in the 2 MONTHS.
