Answer:
$-14
Step-by-step explanation:
4(20)= 80
30+80= -110
-110+96
-14
Step-by-step explanation:
taking money from his account is a minus operation. it lowered the balance.
adding money (like a deposit) is a plus operation. it increases the balance.
so, he did
-4×20 - 30 + 96 = -80 - 30 + 96 = -14
his balance decreased by $14 over this week.
Draw a net for the prism.Find the surface area.
find the equation of the line shown
Find the equation of the line shown in the picture.
Answer:
y = x + 6
Answer:
firstly you have to find the slope of the line.
Step-by-step explanation:
for thus, use the number which is on the coordinate system like x and y. the slope is (10-6)/(4-0) =1 so m=1
the equation should be on this form y-y1=m"(x-x1)
then put the value of y and x from equation.
when the x is 4 the y have to be 10
y-10=1*(x-4)
finally the equation is y=x+6

1. What is the total surface area of the ramp?
The surface area of the triangular prism ramp is: 1,020 ft².
Surface Area of Triangular PrismSurface area = 1/2(base area × height)
The triangular prism has the following dimensions:
base area = 20 × 12 = 240 ft²
height = 8.5 ft
Plug the values into the formula:
Surface area = 1/2(240 × 8.5)
Surface area = 1/2(2,040)
Surface area = 1,020 ft²
Therefore, the surface area of the triangular prism ramp is: 1,020 ft².

can any equation in point-slope form also be written in slope-intercept form?
Answer:
Yes
Step-by-step explanation:
The way the equation is written in point-slope form is:
[tex]y-y1=m(x-x1)[/tex]
The way we write an equation in slope-intercept form is:
[tex]y=mx+b[/tex]
We can change point-slope form to slope-intercept form by first distributing the m and then adding y1 to both sides of the equation. When we do this we will get:
[tex]y=mx-(m*x+y1)[/tex] where [tex](m*x+y1) = b[/tex]
which is now in slope intercept form.

The average electric bill from Duke Energy is $147 with a standard deviation of $32. What is the probability that the bill will be less than $100?
Group of answer choices
93%
10%
7%
17%
The probability that the bill will be less than $100 is 7%
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
[tex]z=\frac{x-\mu}{\sigma} \\\\x=raw\ score, \sigma=standard\ deviation, \mu=mean\\\\\\Given\ that\ \sigma=32,\mu=147,hence:\\\\For\ x<100:\\\\z=\frac{100-147}{32}=-1.47[/tex]
From the normal distribution table, P(x < 100) = P(z < -1.47) = 0.0708 = 7.08%
The probability that the bill will be less than $100 is 7%

Radius or semicircle =7cm
*Area if circle =pi radius 2
=22/7 × 7×7cm 2
=154cm 2
But semicircle is half if a circle so,
Area of a semicircle =1/2 ×154cm2

A power company calculates a person's monthly bill from the number of
kilowatt-hours (kWh), x, used.
The function b(x) = {
0.15x, x < or equal 200
0.10 (x - 200) + 30, x > 200
determines
the bill.
How much is the bill for a person who uses 300 kWh in a month?
A. $45
B. $40
Ο Ο Ο Ο
C. $60
D. $55
please help
Answer:
B. 40
Step-by-step explanation:
if x=300, it means x>200, then b(x)=0.1(x-200)+30; ⇔ b(x)=0.1*100+30= 40 [USD].
The bill for a person who uses 300 kWh in a month is $40.
Option B is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
For a person who uses 300 kWh in a month, we need to use the second part of the function:
b(x) = 0.10(x - 200) + 30, x > 200
Substituting x = 300, we get:
b(300) = 0.10(300 - 200) + 30
b(300) = 0.10(100) + 30
b(300) = 10 + 30
b(300) = 40
Therefore,
The bill for a person who uses 300 kWh in a month is $40.
