Answer:
B
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x - 2 ← is in slope- intercept form
with slope m = 3
• Parallel lines have equal slopes
then slope of parallel line is 3
the equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
here m = 3 and (a, b ) = (3, 5 ) , then
y - 5 = 3(x - 3) ← equation of parallel line in point- slope form
Gas is $2. 09 per gallon at the gas station. If
Nate filled up his car and spent $33. 44, how
many gallons did he put in his car?
Nate's car was filled with 16 gallons of gas.
The concept is used in this is equations. An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values. An equation is the set of variables, constants, and mathematical operations like addition, subtraction, multiplication, or division balanced by an equal sign. For example, 3x + 5 = 15. There are different types of equations like linear, quadratic, cubic, etc.
As gas is $2. 09 per gallon at the gas station.
$2. 09 → per gallon
and Nate filled up his car and spent $33. 44.
$33. 44 for fully filled → how many gallons ?
So,
33.44 / 2.09 = 16 gallons.
Therefore, Nate filled 16 gallons gas in his car.

Elizabeth has a loyalty card good for a 10% discount at her local grocery store. What would her total in dollars and cents be, after the discount and before tax, if the total cost of all the items she wants to buy is $37. 60? Round to the nearest cent
The total amount for Elizabeth's purchase after 10 percent discount on her total bill is 33 dollars and 84 cents which is equivalent to 34 dollars.
What is percentage?
A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
Elizabeth bought the grocery for a total of 37 dollars and 60 cents.
She has a coupon of 10% discount.
Which means, she can get 10% discount on her total bill.
The amount of her total bill is $37.60.
So, calculate using percentage, the value of 10% of $37.60.
=(10 × 37.60/100)
= 376/100
= 3.76
So, Elizabeth would get a discount of $3.76 on her total bill -
= 37.60 - 3.76
= 33.84
Therefore, after the discount Elizabeth's total bill is $33.84 ≈ $34.

a cell phone company has a basic monthly plan of $40 plus $0.45 for any minutes used over 700. Before receiving his statement, John saw he was charged a total of $48.10. Write and solve an equation to determine how many minutes he must have used during the month. write an equation without decimals.
Answer: 718
Step-by-step explanation:
The formula for determining the cost of the cell phone bill (when more than the base number of minutes is used) is
c=p+(m−b)r
Where:
c is the total cost of the bill: $48.10 for this problem.
p is the base price of the plan: $40 for this problem.
m is the number of minutes used: what we are solving for this problem.
b is the base number of minutes allowed: 700 for this problem
r is the rate for additional minutes: 0.45 for this problem
Substituting and solving for m gives:
$48.10 = $40.00 + (m − 700)$0.45
$48.10 − -$40- = $40.00 − -$40- + (m − 700)$0.45 $8.10= 0 + (m−700)$0.45
$8.10 = (m - 700)$0.45
$8.10 = ($0.45 × m) − ($0.45 × 700)
$8.10 = $0.45m − $315.00
$8.10 + -$315.00- = $0.45m − $315.00 + -$315.00-
$323.10 = $0.45m − 0
$323.10 = $0.45m
[tex]\frac{323.10}{-0.45-}=\frac{0.45m}{-0.45-}[/tex] (Money)
[tex]\frac{323.10}{0.45}=\frac{0.45m}{0.45}[/tex] (Money): cross out the dollar sign for 323.10 and 0.45 under it... then cross out 0.45m but leave the m, and then cross out 0.45 under it.
[tex]\frac{323.10}{-0.45-}=m[/tex]
718 = m
m = 718

Left Riemann sum approximation Question...
The left Riemman sum approximation for f(x) = x^5, between x = 0 and x = 5, considering 5 intervals, is given as follows:
5.3248.
How to obtain the Riemman sum approximation?First we must obtain the Delta value, which is the difference between the bounds of the integral, divided by the number of integrals, thus:
[tex]\Delta_x = \frac{b - a}{n} = \frac{2 - 0}{5} = 0.4[/tex]
Then the values of x at which the numeric values are calculated are obtained as follows:
[tex]x_i = a + \Delta_x(i - 1)[/tex]
Thus the values of x are of:
[tex]x_1 = 0[/tex].[tex]x_2 = 0.4[/tex][tex]x_3 = 0.8[/tex][tex]x_4 = 1.2[/tex][tex]x_5 = 1.6[/tex]The numeric values are given as follows:
f(0) = 0^5 = 0.f(0.4) = 0.4^5 = 0.01024.f(0.8) = 0.8^5 = 0.32768.f(1.2) = 1.2^5 = 2.48832.f(1.6) = 1.6^5 = 10.48576.Then the Riemann sum approximation for the integral is given as follows:
[tex]\sum_{i = 1}^{n} \Delta_x f(x_i)[/tex]
Thus:
0.4(0 + 0.01024 + 0.32768 + 2.48832 + 10.48576) = 5.3248.

Quadrilaterals A and B are similar. The area of quadrilateral A is 5cm². Calculate the area of quadrilateral B. 3cm 63° 87° 120° A 90° 15cm 63 87° B 120° 90°
Answer: 25cm²
Step-by-step explanation:
Ok, so I haven't actually learnt this in school so I'm going to give it my best shot. (Don't be surprised if I get this wrong though.)
So, Quadrilaterals A and B are similar. They have the same angles. Therefore, (I'm thinking that) Quadrilateral B is just a scaled-up version of Quadrilateral A.
Here comes my theoretical part:
If one side of Quadrilateral B is 5 times longer than the same side of Quadrilateral A...
(Quadrilateral A is 3cm, and Quadrilateral B is 15cm).
... then the area of the entire Quadrilateral B should just be 5 times bigger than Quadrilateral A.
Therefore, (I'm guessing), Quadrilateral B has an area of 25cm²

(ANSWER QUICKLY PLAESE) Mrs. Rubio collected $5 from
each student and $8.25 from each
chaperone for a field trip. She collected
a total of $176.25. If 5 chaperones went
on the field trip, how many students
went?
Answer:
27 students
Step-by-step explanation:
We know
1 student = $5
1 chaperone = $8.25
5 chaperon = $8.25 x 5 = $41.25
Let's solve
$176.25 - $41.25 = $135
So, we know that the total amount Mrs. Rubio collected from students is $135, then we take
135 / 5 = 27 students
So, 27 students went on the field trip.
Answer:
8.25 × 5 = 41.25
176.25 - 41.25 = 135
5 × x = 135
x = 27
Therefore, 27 students went.

The slope-intercept forms for the graphs 5, 6, 7, and 8 are - y = (-1/2)x + 6, y = 50x + 150, y = (10/3)x + 20, and y = 25x respectively.
What is slope-intercept form?
The line with m as the slope, m and b as the y-intercept is the graph of the linear equation y = mx + b. The values of m and b are real integers in the slope-intercept form of the linear equation.
First, find out the y-intercept(s).
The y-intercepts are the starting point of the lines in the graph.
For graph number 5, the starting point is 6.
For graph number 6, the starting point is 150.
For graph number 7, the starting point is 20.
For graph number 8, the starting point is 0.
Now find the slopes.
For graph number 5, the line goes down 1 unit and moves to the right 2 units, so the slope would be -1/2 (rise/run).
For graph number 6, the line goes up 100 units and moves to the right 2 units, so the slope would be 100/2 (rise/run) or 50.
For graph number 7, the line goes up 10 units and moves to the right 3 units, so the slope would be 10/3 (rise/run).
For graph number 8, the line goes up 25 units and moves to the right 1 unit, so the slope would be 25/1 (rise/run) or 25.
Then plug into the slope-intercept form : y = mx + b.
Where, m is slope and b is the y-intercept.
Graph 5: y = (-1/2)x + 6.
Graph 6: y = 50x + 150.
Graph 7: y = (10/3)x + 20.
Graph 8: y = 25x + 0 or y = 25x
Therefore, the equations are - y = (-1/2)x + 6, y = 50x + 150, y = (10/3)x + 20, y = 25x.

What is percentage ?
A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.
In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. Percentage, a relative value showing hundredth parts of any amount, is a relative measure that indicates how many questions on a test you correctly answered out of 100 (75/100). Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified percentage.

On solving the provided question, by properties of parallel lines we got to know that - 1 - A 2 - C 3 - B 4 - D
what is alternate exterior angles?When two or more lines cross the intersection line, alternate exterior angles result. These angles are created on a number of sides outside the transverse lines. Any two parallel lines that cross one another create two angles with the horizontal line. In the area between the parallel lines, interior angles are formed, while alternate exterior angles are formed in the area outside the parallel lines.
Matches are -When two parallel lines cross one other, the horizontal line is divided into two angles. Interior angles develop between the parallel lines, whereas alternative outside angles develop outside the parallel lines.
1 - A
2 - C
3 - B
4 - D
