Anyone can help me with math for solving for a side in the right triangles for khan academy

Answers

Answer:

7.45

Step-by-step explanation:

We are given a right triangle with one side length known and an angle know so we can use some trigonometry.

You need to find the hypotenuse so you are going to use either sine or cosine.

Since the adjacent from the angle is given (SOH-CAH-TOA) we can use cosine so,

cos(20) = 7/h

=>h = 7/cos(20)

=> 7.44924

=> 7.45

If the mean of a normal distribution is 26 what is the median of the distribution A. 18 B. 14 C. 26 D. 22

Answers

Answer:

C. 26

Step-by-step explanation:

Since in the question it is mentioned that the mean of the normal distribution is 26 and also as we know that the normal distribution considered to be symmetric so the mean would be equivalent to the median

As in the question the mean is 26 so the median would also be 26

hence, the correct option is C.

Can someone help. “At the market you can buy 5 bags of apples for $23.60. At the orchard you can get 7 bags of apples for $32.76. Which is the better deal?”

Answers

Answer:

7 for $32.76

Step-by-step explanation:

23.60/5 is $4.72

32.76/7 is $4.68

Answer: $4.72

Step-by-step explanation:

To solve this problem we need to find the unit price of a bag of apples(one bag)

Thus, simply do 23.60/5 to get 4.72 and 32.76/7 to get 4.68.  Because 4.68 < 4.72, the orchard is a better deal.

m = 2.5

n = 5

m+(79)/n

2.5 + 7 - 9

=0.5

divide by 5

= 0.1

M=2.5 so first u multiply 7 and 9 and that should equal 63 and then u add 2.5 to 63 and that will equal 65.5 and then u divide 65.5 by 5 since n = 5 and that should equal 13.1 so d is ur answer

To make 8 cups of tomato soup you need 2 pounds of tomatoes. How many pounds of tomatoes do you need to make 32 cups of soup? ​

Answers

8 pounds of tomatoes

If 8 cups of soup = 2 pounds of tomatoes

Then you take 32/8 = 4
Then multiply 2x4 to get eight pounds of tomatoes

Answer:

[tex]8 cups[/tex]

Step-by-step explanation:

For 8 cups, you need 2 pounds. For 32, you just divide it by 8, which is 4. 4x2=8, so it’s 8 cups. Have a nice day.

What is the distance (in units) between points C and D? Round your answer to the nearest hundredth. c(-5,-1) d(0,3)

Answers

Answer:

6.4

Step-by-step explanation:

The whole thing is like a triangle, with the distance between the points as the hypotenuse.

Use the pythagorean theorem, a²+b² = c².

To calculate a, calculate the distance between the x-values of (-5,-1) and (0.3) by subtracting.

0-(-5) = 5

a = 5

To calculate b, calculate the distance between the y-values of (-5,-1) and (0.3) by subtracting.

3-(-1) = 4

b = 4

now plugin a = 5 and b = 4 into the pythagorean theorm to calculate c, or the distance.

5²+4² = c²

25+16 = c²

41 = c²

√41 = √c²

c = 6.4
