Answer:
Step-by-step explanation:
depends how much money is deposited, however, the choices can be just D or E
Answer:
B,D,E
Step-by-step explanation:
Does it say how much was deposited? Ok so deposit means your bank gets bigger so it cannot be less than -28.
My guess is that it will be either B,D,E
The reason I say my guess is because I think the question should have given you an amount of how much was deposited.
Pat earns $30.00 for traveling to the homes plus $10.50 for each hour of tutoring. Write a linear equation that models their total earnings for traveling and tutoring for a given number of hours.
Answer: 30 + 10.50h
Step-by-step explanation:
From the question, we are informed that Pat earns $30.00 for traveling to the homes plus $10.50 for each hour of tutoring.
The linear equation that models their total earnings for traveling and tutoring for a given number of hours would be written as:
= $30 + $10.50h
where h represents the number of hours for tutoring used.
For example, if 2 hours if tutoring was used, the total amount earned would be:
= 30 + 10.50h
= 30 + 10.50(2)
= 30 + 21
= $51
(7x2 – 4) - (3x2 – 5x + 1)
Step-by-step explanation:

-1/5x≤8
what is the aswer
Hey there!
“-1/5x ≤ 8”
MULTIPLY both sides by -5
-1/5x × -5 ≤ 8 × 5
CANCEL out: -1/5 × -5 because that gives you 1
KEEP: 8 × 5 because that helps us solve for your given equation
NEW EQUATION: x ≥ 8 × 5
8 × 5 = 40
Answer: x ≥ 40
It is a CLOSED circle SHADED to the RIGHT
Write in slope-intercept form an equation of the line that passes through the points (−4, 2) and (6,−3).
Answer:
y = -0.5xStep-by-step explanation:
[tex]\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
(−4, 2) ⇒ x₁ = −4, y₁ = 2
(6,−3) ⇒ x₂ = 6, y₂ = −3
So the slope:
[tex]\bold{m=\dfrac{-3-2}{6+4}=\dfrac{-5}{10}=-0.5}[/tex]
The point-slope form of the equation of the line passing through point (x₀,y₀) and with slope m is: y - y₀ = m(x - x₀)
m = -0.5
(−4, 2) ⇒ x₀ = −4, y₀ = 2
Therefore:
y - 2 = -0.5(x - (-4))
y - 2 = -0.5x - 2 {add 2 to both sides}
y = -0.5x ← the slope-intercept form of the equation (b=0)
2) 50 apples cost $25. How much would 75 apples cost?
Answer:
50 : 25 = 75 : 37.50
Step-by-step explanation:
If 50 apples cost $25, that means 2 apples cost $1.
75 apples cost 37.5, or $37.50

find the total to the nearest cent $24 lunch 15% tip# show work
Answer:
$27.60
Step-by-step explanation:
First, we need to find how much the tip is:
we can convert 15% directly to a decimal:
15% = 0.15
Then we find :
15% of 24 = 0.15 x 24 = 3.59999999999999
3.599999999999999 to the nearest cent is 3.60
Then we add the tip to the original bill:
3.60 + 24 = 27.60
So the total cost of the lunch is $27.60
Sorry the quality is bad- I’ll mark brainlist
Answer: A and C
Step-by-step explanation:
Can someone please show me the working out because I really don’t know how to find the area of this.
Step-by-step explanation:
Base of smaller pink triangle
= (3m + 6m) - 7m = 2m.
Area of smaller pink triangle
= 0.5(2m)(5m) = 5m².
Area of bigger pink triangle
= 0.5(6m)(5m) = 15m².
Hence total area shaded = 5m² + 15m² = 20m².

In pedros town 42% of the houses have both internet service and a home phone. If 82% of all the houses in his town have internet service, what is the probability that a house has a home phone if it has internet service?
Answer: 0.51
Step-by-step explanation:
We know that:
For a random selection, we have a probability of 0.42 where the house has both services and a probability of 0.82 that the house has only internet service.
Let's suppose that the percentage of houses the houses with internet service (the 82% of the total) that also have a home phone is X
Then we must have that, (X/100%) times the 0.82, must be equal to 0.42
(X/100%)*0.82 = 0.42
X = (0.42/0.82)*100% = 51%
This means that 51% of the houses with internet service, also have a home phone.
Then the probability that a house has a home phone given that it has internet service, is equal to:
51%/100% = 0.51
The probability is 0.51

Kayla gets paid $15 to rake the lawn. Kayla gets paid 3 times as
much to rake the lawn as she does to mow the lawn. How much
does Kayla get paid to mow the lawn?
Answer:
$5
Step-by-step explanation:
The opposite of multiplication is division.
$15/Raking = 3 times more pay than mowing the lawn.
Divide $15/Raking by 3 and you'll get the pay for mowing the lawn.
15/3 = 5

How does the graph of the function f(x) = 2x4− 3 differ from the graph of its parent function? Select all the transformations.
◻A.The graphs are the same.
◻B.Subtracting 3 translates the graph down 3 units.
◻C.The leading coefficient, 2, stretches the graph vertically.
◻D.Subtracting 3 translates the graph up 3 units.
◻E.Subtracting 3 translates the graph right 3 units.
Answer:
B and C are the correct options
Step-by-step explanation:
The parent function here will be ;
f(x) = x^4
Multiplying x^4 by 2 means that we are having a vertical stretching
What this means is that the leading coefficient 2 stretches the graph vertically by 2 units
Subtracting -3 means that we are translating the graph down by a value of 3 units
So the correct options are;
B and C

Which statement describes a unit rate? Group of answer choices Sara is reading 97 words in 1 minute. Sara ate 3 crackers and 1 apple. Sara ate 1 cookie. Sara is driving 16 miles.
Answer:
97 words in 1 minute
Step-by-step explanation:
A unit measure is so many somethings done usually per unit time. Examples
1 orange in 1 minute.10 tomatoes per tomato plant50 miles in one hour10 cookies per week3 crackers and 1 apple is not. For ever apple, she ate 3 crackers would be
1 cookie is not. It is not per anything.
Driving 16 miles is not. Again, it is not per anything.
The answer is 97 words in 1 minute.
Write the number 5267 correct to
the nearest hundred.
Answer:
5300.
If you're rounding to the nearest hundred you look at the tens place. If its 5 or over you go up. So in this case we'll raise the 2 to a 5 because 6 is above 5.
Harper knows he is 50 yards from school. The map on his phone shows that the school is 3/4 inch from his current location. How far is Harper from home, if the map shows the distance as 3 inches? Enter your answer in the box.
Answer:
Harper is 200 yards away from her home if the map shows 3 inches
Step-by-step explanation:
50 yards = 3/4 inch
3 inches = 3/1
3/1 x 4/4 = 12/4
12/4 = 3 inches
50 x 4 = 200

A $30 shirt is marked, "Get 25% off." What is the sale price of the shirt?
Answer:
$22.50
Step-by-step explanation:
First, we find how much we need to take off so our equation is:
30 x 0.25 = 7.5
So, we take 7.5 off of 30 which is:
30 - 7.5 = 22.5
So, the shirt is selling for $22.50

The speed of light is about 300,000 kilometers per second. The Sun is about 93 million miles from Earth. How many minutes does it take for the sunlight to reach Earth? Round to the nearest tenth if necessary.
Answer: 8.3 minutes
Step-by-step explanation:
1 mile is to 1.60934km so 93 million miles is:
= 93 * 1.609
= 149,637,000 km
Travelling at 300,000 km per second, the number of seconds it takes is:
= 149,637,000/300,000
= 498.79 secs
In minutes this is:
= 498.79/60
= 8.3 minutes
From the expressions below, select the one that results in a negative difference.
