The gradient of a line which perpendicular to C is -3/2
How to determine the gradientThe gradient of a line shows how steep it is. Gradient is also called the slope of a line.
Let's use the fact that the product of the gradients of two perpendicular lines is -1 to determine the gradient of a line perpendicular to line C.
We can determine the gradient of the line perpendicular to C if the gradient of line C is 2/3.
Take the negative reciprocal of the gradient, we have;
-3/2
Since the negative reciprocal of 2/3 is -3/2.
Therefore, the gradient of the line perpendicular to C is -3/2.

The correct statement about the median will be the following which is calculated from average wind speeds as:
The median wind speed for country B is greater than the median wind speed for country A.The median wind speed for A is about 7 miles.The median wind speed for B is about 9 miles.What is median?
It is the center most number of the data available to us which divides the data in 2 equal parts.
How to calculate median?
We have been given the average wind speeds of two countries.
Median of country A =(1+9.5)/2 th term in the box
=5.25th term in the box which is 7.
Median of country B=(1.2+11)/2
=6.1 th term which is 9.

Will give brainliest answer What is the value of a21? A.36 B. 58 C.60 D. 41
Answer:
41
Step-by-step explanation:
Matrix Multiplication follows a row-column format. In order to compute this, you must be familiar with vector dot products.
With that in mind, lets get straight into it.
The order that matrix multiplication follows means that the terms in the result are filled in left to right, then top to bottom.
Therefore, a21 will be the 3 value that is computed. This is important becuase this allows to directly compute a21, instead of using up a lot of time computing all the values before.
As a21 is located in the bottom row 1st column, we take the dot product of the 2nd row in matrix 1 and the 1 column in matrix two.
So we have:
(7 2) dot (5 3) = 7*5 + 2*3 = 41
The parallelogram shown below has an area of 30 units2
Answer:
6
Step-by-step explanation:
The formula for the area of a parallelogram is the base times height.
We know the base is 5, and the area is 30, so:
5x=30
x= 6
So the height is 6
Answer:
The area of a parallelogram is A= bh so since the base is 5, the height is 6
6 x 5 = 30^2

11 games and lost 4. Because of a couple of rainouts,
the Cubs won 10 games and lost 3. Find percent of the
games both teams won.
3. The price of a stock was $52.63 when the stock market

4. In Kendra's school, 28 percent of seven graders went
to a movie theater over the weekend. If there are 800
students in the seventh grade, how many of them saw
a movie?
Answer:
Step-by-step explanation:
1) Let x represent the sale price.
normal price = $39.95. This week they are on sale for 25% off the regular price. The amount taken off is
25/100 × 39.95 = 9.9875
Sale price = 39.95 - 9.9875 = $29.9625
2) number of games played by the tigers is 11 + 4 = 15
Percentage of games won is
11/15 × 100 = 73.3%
number of games played by the cubs is 10 + 3 = 13
Percentage of games won is
10/13 × 100 = 76.9%
3) increase in stock price = 61.5 - 52.63 = $8.87
Percentage increase = 8.87/52.63 × 100 = 16.85%
4) if 28 percent of seven graders went
to a movie theater over the weekend and there are 800 students in the seventh grade, then the number of seven graders that saw
the movie is
28/100 × 800 = 224

Since you are finding the AREA, you always have to multiply length by width. So, 5 ft x 3 ft= 15 ft
Lisa has a gym membership at Lifetime Fitness. It costs $29.95 to join and she also pays a monthly charge. Lisa has been a member for 11 months. She has paid a total of $298.90 for her membership. Write an equation that could be used to find, m, the monthly membership fee.
What is the monthly membership fee?
Answer:
298.90 - 29.95 = (ANSWER) divide it by 11 then you will have the monthly cost
Step-by-step explanation:
Answer:
monthly paid= 24.45
Step-by-step explanation:
if we take membership join fee=x=29.95
and the monthly fee=m
so the equation will be
11 m + x =298.90
so by substitute x
m=24.45 $/month
Simon offered a customer a cubic box with 3-inch sides. The customer told Simon to increase each side of the box by an inch
Answer:
64 [tex]in^{3}[/tex]
Step-by-step explanation:
The volume of a cubic box with side length of s inches can be calculated using the following formula
[tex]V = s^{3} in^{3}[/tex]
If the initial side length was 3 inches and the customer asked Simon to increase each one of the sides of the box by one inch, then the new side lengths now become 4 in (3+1 = 4)
[tex]V = 4^{3} in^{3} = 64 in^{3}[/tex]
Therefore the final and new volume is
64 [tex]in^{3}[/tex]
Answer:
The volume of the new box is 64 cubic inches. If each side of the box was increased by 1 inch, the new measure of each side would be 4 inches. 4 times 4 times 4 equals 64.

20 boxes of apples have been delivered to a restaurant. The number of apples in each box is counted. Complete the table below and answer the following question. What is the mean number of apples in a box?
Answer:
30 apples
Step-by-step explanation:
600 is the total number of apples (adding all numbers in the apples*frequency column). Dividing this by 20, the number of boxes, we get 30 apples as the mean number in a box.
The mean number of apples is the result of dividing the product of frequency and number of apples and f in the table given. Hence, the mean number of apples is 30
The sum of frequency = (2 + 4 + 8 + 4 + 2) = 20
The sum of fx = (56 + 116 + 240 + 124 + 64) = 600
The mean number of apples can be calculated using the values obtained thus :
Mean = fx ÷ f
Mean = 600 ÷ 20
Mean = 30
Therefore, the mean number of apples in a box is 30

A company makes concrete bricks shaped like rectangular prisms. Each brick is 10 centimeters long, 6 centimeters wide, and 4 centimeters cm tall. If they used 13,000cm³ of concrete, how many bricks did they make?
Answer: 54 bricks
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a rectangular prism (V) : length x width x height
Replacing with the values given and solving for v (Volume)
V = 10 x 6 x 4
V = 240 cm3 (volume of one brick)
Finally, we have to divide the amount of concrete used by the volume of each brick:
13,000cm³ /240 cm3 = 54.16 = 54 bricks

Two sides of an obtuse triangle measure 10 inches and 15 inches. The length of longest side is unknown. What is the smallest possible whole-number length of the unknown side? 18 inches 19 inches 24 inches 25 inches
Answer:
19 inches is the correct answer.
Step-by-step explanation:
Side 1 = 10 inches
Side 2 = 15 inches
It is given that it is an obtuse angle triangle i.e. the largest angle of the triangle is more than [tex]90^\circ[/tex].
Let us suppose, that the triangle be a right angle triangle, then the largest angle will be [tex]90^\circ[/tex]. The largest side is known as Hypotenuse.
As per pythagoras theorem:
[tex]Hypotenuse^{2} = Base^{2} + Height^{2}[/tex]
[tex]\Rightarrow 10^{2} + 15^{2} = Hypotenuse^2\\\Rightarrow 325 = Hypotenuse^2\\\Rightarrow Hypotenuse = 18.04\ inches[/tex]
So, largest side comes out be 18.04 inches.
But actually, the largest angle is more than [tex]90^\circ[/tex] so the largest side will also be greater than 18.04 inches.
Hence, the answer is:
Smallest possible whole number length of unknown side will be 19 inches.

In calculating the monthly payment for a five-year loan, what value should be used for n, the number of periods over which the loan is repaid, as it appears in the following formula? P = P V times StartFraction i over 1 minus (1 + i) superscript negative n EndFraction
a.5
b.12
c.60
d.120
The answer is C,60
Answer:
C
Step-by-step explanation:
EDGE2021
The value should be used for n, the number of periods over which the loan is repaid in 60 periods.
What formula is used to calculate the monthly payment?The value of the monthly payment is given by;
P = PV × i / 1-(1+i)⁻ⁿ
Where,
PV is the present value or the amount of the loan.
i is the interest rate per period and is calculated by dividing the yearly percent rate by 100 and by the number of periods in a year.
n is the total number of periods and is calculated as the product of the number of periods in a year times the number of years.
Therefore,
The value should be used for n, the number of periods over which the loan is repaid;
n = 6 years × 12 months/year = 60 months = 60 periods.
Hence, The value should be used for n, the number of periods over which the loan is repaid in 60 periods.
