What rule would you allow to test weather (x,y) is on line l
Answer:
Step-by-step explanation:
If a point (x, y) lies on a straight line, coordinates of the point will satisfy the equation.
Slope of a line passing through two points C(4, 5) and D(8, 10),
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{10-5}{8-4}[/tex]
m = [tex]\frac{5}{4}[/tex]
Equation of the line passing through C(4, 5) and slope m = [tex]\frac{5}{4}[/tex]
y - y' = m(x - x')
y - 5 = [tex]\frac{5}{4}(x-4)[/tex]
y = [tex]\frac{5}{4}x-5+5[/tex]
y = [tex]\frac{5}{4}x[/tex]
If point B(4, 0) lies on the line CD,
0 = [tex]\frac{5}{4}(4)[/tex]
0 = 5
Which is not true.
Therefore, point B doesn't lie on line CD.
please help me.. if you could explain too that would be great.

What is 2.31 of 5.02
Answer:
11.5962
Step-by-step explanation:
2.31 of 5.02
In mathematics, saying "of" is the same as multiplying the two values, hence the problem is;
2.31 * 5.02
= 11.5962
What is the value of n of this data? Type a numerical answer in the space provided. Do not type spaces or decimals in your answer.
3, 12, 15, 25, 30, 40
Answer:
The value of n for this data is 6
Step-by-step explanation:
The given data is:
3, 12, 15, 25, 30, 40
In a set of given data, n is used to represent the number of values in a dataset. The values are also called observations. Hence, the total number of observations in a dataset are denoted by n.
In the given dataset, total values are 6.
So,
n = 6
Hence,
The value of n for this data is 6
2. Similar rectangles have widths of 10 cm and 15 cm respectively. If the smaller rectangle's length is 18, what is the larger rectangle's length?
Answer:
8
Step-by-step explanation:
10/15=0.66666666666
0.66666666666 times 12 = 8 or the missing length
So the answer is 8 :)

In the equation, we are told that d(t) = 300,000t, where t is the time in seconds and d(t) is the distance in kilometers.
1. In this part of the question, it asks for the distance after 15 seconds. To solve we plug 15 in for t.
d(t) = 300,000(15)
d(t) = 4500000 kilometers
2. In this part of the question, it is asking for time after going 12,000,000 kilometers (twelve million). To solve, we solve for t by dividing 300,000.
12,000,000 = 300,000(t)
40 = t

Shayla bought 24 cupcakes. Each cupcake cost $0.35, including tax. Of the cupcakes she bought, 2 3 2 3 were vanilla, 1 12 1 12 were chocolate, and the rest were strawberry. What was the total cost of only the vanilla cupcakes?
Answer:
[tex]Vanillas = \$5.6[/tex]
Step-by-step explanation:
Given
[tex]Cup\ Cakes = 24[/tex]
[tex]Cost = \$0.35[/tex] (each)
[tex]Vanilla = \frac{2}{3}[/tex]
[tex]Chocolate = \frac{1}{2}[/tex]
Required
Determine the cost of all vanilla cupcakes
First, we need to determine the number of vanilla cakes.
This is calculated by multiplying the fraction of Vanilla by number of cupcakes
So:
[tex]Vanilla = \frac{2}{3} * 24[/tex]
[tex]Vanilla = \frac{2 * 24}{3}[/tex]
[tex]Vanilla = \frac{48}{3}[/tex]
[tex]Vanilla = 16[/tex]
Since 1 cupcake costs $0.35.
16 would cost 16 * $0.35
So:
Vanillas: ;;;;; [tex]16 * \$0.35 = \$5.6[/tex]
Rectangles P, Q, R, and S are scaled copies of one another. For each pair, decide if the scale factor from one to the other is greater than 1, equal to 1, or less than 1. Four rectangles, labeled P, Q, R and S. Each rectangle is a scaled copy of one another. Ranked in order from least to greatest, the area of the rectangles are as follows: the area of P is equal to S, which are less than the area of Q, which is less than the area of R. From P to Q from P to R from Q to S from Q to R from S to P from R to P from P to S
I attached a diagram that will aid the understanding of the question.
Firstly, I would love to review what a scale factor is before going into the question.
If you have two shapes that are similar, that is they have corresponding angles, then the scale factor of one to the other is simply the ratio of any two corresponding lengths in the two similar geometric figures.
Looking at these figures in the question, we see that R is an enlargement of the other rectangles while Q is an enlargement of P and S. With this information we can answer the questions:
1. From P to Q, the scale factor greater than one because Q is bigger than P.
2. From P to R, the scale factor is greater than one for the same reason.
3. From Q to S, the scale factor is less than one because S is smaller than Q.
4. From Q to R, the scale factor is greater than one because R is bigger than Q.
5. From S to P, the scale factor is equal to one because they are equal.
6. From R to P, the scale factor is less than one because p is smaller than R.
7. From P to S, the scale factor is equal to one because they are equal.
Kedar earns a monthly salary of $2,200 plus a 3.75% commision on the amount of his sales at men's clothing store. What would he earn this month if he sold $4,500 in clothing?
Answer:
$2368.75
Step-by-step explanation:
Kedar earns a monthly salary of $2200 and a commission of 3.75%
He sold $4500 this month
The first step is to calculate his commission for this month
His commission can be calculated as follows
= 4500 × 3.75/100
= 4500 × 0.0375
= 168.75
Therefore yr amount earned this month can be calculated as follows
= 2200 + 168.75
= $2368.75

A person jogs 4 kilometers in 32 minutes, the 2 kilometers in 22 minutes, and finally 1 kilometer in 16 minutes. What is the jogger's average speed in kilometers per minute?
Answer:
0.1km per minStep-by-step explanation:
what is average speed:
"The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time."
step one:
given data
Distances Time
4km 32min
2km 22min
1km 16min
the total distance covered is
4+2+1= 7km
the total time taken = 32+22+16=70min
the average speed= distance/time
average speed= 7/70= 0.1km per min

Step-by-step explanation:
Using distributive property, we can simplify 8(2x-3) to 16x-24. That becomes 16x-24+11x.
Then, we can add 16x and 11x to get 27x.
The answer will be 27x-24.

It rained all day on Mother's Day and the temperature dropped fourteen and seven tenth degrees. The next day the rain stopped and the temperature rose ten and nine tenths degrees. If the temperature at the beginning of Mother's Day was sixty five and eight tenths degrees, what was the temperature at the end of the day after Mother's Day?
Answer: The temperature was 1 8/10º at the end of the day after Mother's Day
Step-by-step explanation:
5 8/10º-14 7/10º=-9 1/10º at the end of Mother’s Day
-9 1/10º+10 9/10º=1 8/10º at the end of the next day after Mother’s Day
