Question 1 (1 point)
1. Which three lengths could be the lengths
of the sides of a triangle?
O A.12 cm, 5 cm, 7 cm
O B.10 cm, 15 cm, 24 cm
O C.9 cm, 22 cm, 11 cm
O D.21 cm, 7 cm, 6 cm

Answers

Answer 1

Answer:

B

Step-by-step explanation:

For three side lengths to make a triangle, the two smaller ones have to add up to be greater than the third one. This is because if they are any smaller, they won't be able to touch and form a triangle. The formula for this is a+b>c.

You can go through each answer choice and determine whether or not it would work:

A. 12, 5, and 7

5 + 7 > 12 --> 12 > 12 (NOT true)

B. 10, 15, and 24

10 + 15 > 24 --> 25 > 24 (true!)

C. 9, 22, 11

11 + 9 > 22 --> 20 > 22 (NOT true)

D. 21, 7, and 6

7 + 6 > 21 --> 13 > 21 (NOT true)

This means that the correct answer is B.

Write down three integers,all less than 25,whose range is 8 and mean is 11.

Answers

let

x------> the first integer

y------> the second integer

z-----> the third integer

x < y < z < 25

we know that

Median=13

Median=(x+y+z)/3

13=(x+y+z)/3

x+y+z=39------> equation 1

range=10

The range is the difference between the largest number within the set and the smallest number in the set

so

range=z-x

z-x=10------> z=x+10-----> equation 2

to find the solution we will assume different values ​​of x (See the attached table)    

terms

x < y < z < 25

z=x+10

y=39-z-x

The solution can be

7,15,17

8,13,18

How many miles of trail does Ammar hike per hour?

Answers

Answer:

.42 mph

Step-by-step explanation:

The problem tells us theres 2.75/1.15 miles/hour. And we want to know x/1 miles/hour. To do this you cross-multiply using whats been referee to as the butterfly method. So take 2.75*x=1.15*1. Then you simplify and get 2.75x=1.15. To get x along you must divide which leaves you with. X=.4182(rounded). So you can go .42 miles per hour.

The perimeter of a flag is 474 inches. The flag is 100 inches tall. How long is it?

Answers

The answer is 136 I hope this helped
Okay let’s go step by step.

If it is 100 inches tall, there are two sides that are the same length since flags are rectangles. 100 x 2 = 200. 474 - 200 = 274. 274 divided by two (we are dividing by two because there are two sides congruent on the flag) is 137.

Part A:  y = 4.5x + 22

Part B:  31 inches

Step-by-step explanation:

Part A:

the y-intercept appear to be at 22

the slope can be found by using the points (0, 22) and (4, 39)

m = 39 - 22

        4 - 0

m = 17 / 4 = 4.3 and this is close to 4.5

Part B:

plug in 2 for 'x' in the equation: y = 4.5x + 22

y = 4.5(2) + 22

y = 9 + 22

y = 31
