Answer:
are you sure there isn't a 90?
Step-by-step explanation:
Because there are 4 quarters in a whole, so 22 x 4 = 88, and there are 2 quarters in 1/2 so it would be 88+2, which is 90.
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)
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
Can anybody answer this??
Answer:
(x, y) represent coordinates, m represents slope, and b represents the y-intercept
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.

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

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
Answer:
5

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

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
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

please help!!
Answer:
1=(4/4)*(4/4)
2=(4/4)+(4/4)
3 = (4+4+4)/4
4 = 4 + (4-4)*4

20=4 × (4/4 - (-4))

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
Hope this helps:)

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.

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.
