Answers

Answer 1

Answer:

< i = 21.6 degrees

Step-by-step explanation:

Side KI = 5.3 ft

Side JK = 2.1 ft

To find :  = ?

Answer 2

Answer:

22°

Step-by-step explanation:

to get the value of angle I, use the formula: x tan⁻¹Ф = h

where: x = 5.3

           h = 2.1

          Ф = ?

plugin values into the formula;

5.3 tan⁻¹Ф = 2.1

tan⁻¹Ф  = 2.1  

               5.3

           ≈ 22°

If JL = 16, KM = 4x-1, and KM is a perpendicular bisector of JL, determine which of the following values are correct. Select ALL that apply.
A.x = 3
B.JK = 11
C.KM = 15
D.KL = 17
E.Perimeter of triangle KLM = 22
F.Perimeter or triangle JKL = 50

Answers

*see attachment for diagram

Answer:

C.KM = 15

D.KL = 17

F.Perimeter or triangle JKL = 50

Step-by-step explanation:

Given:

JL = 16,

KM = 4x-1

JK = 6x - 7

KL = 5x - 3

✔️Thus, let's find the value of x

Since KM is a perpendicular bisector of JL, it means JM = LM = ½*16 = 8

KM in ∆KJM is equal to KM in ∆KLM.

The angles opposite the two corresponding congruent sides in both triangles are also congruent to each other. Therefore, the third corresponding side and angles would be congruent to each other.

Thus:

JK = KL

6x - 7 = 5x - 3 (substitution)

Collect like terms

6x - 5x = 7 - 3

x = 4

✔️Find JK:

JK = 6x - 7

Plug in the value of x

JK = 6(4) - 7

JK = 24 - 7

JK = 17

✔️Find KM:

KM = 4x - 1

Plug in the value of x

KM = 4(4) - 1

KM = 16 - 1

KM = 15

✔️Find KL:

KL = 5x - 3

Plug in the value of x

KL = 5(4) - 3

KL = 20 - 3

KL = 17

✔️Find the Perimeter of ∆KLM:

Perimeter of ∆KLM = KM + KL + LM

= 15 + 17 + 8

= 40

✔️Find the Perimeter of JKL:

Perimeter of ∆JKL = JK + KL + JL

= 17 + 17 + 16

= 50.

The correct values are:

C.KM = 15

D.KL = 17

F.Perimeter or triangle JKL = 50

Answers

Answer:

6th

Step-by-step explanation:

the chart says not, 7th has majority

The students of grade 6 are more likely to be members of the public library

What is probability?

Probability is the ratio that shows the likelihood an event will occur or not from a given set of events.

The students of which grade are more likely to be members of the public library are determined below:

Grade 6:

The total number of students who are a member of the public library = 25

The total number of students = 28

P(grade 6 students who are members of the public library.) = 25/28

= 0.892

Grade 7:

The total number of students who are a member of the public library = 23

The total number of students = 30

P(grade 6 students who are members of the public library.) = 23/30

= 0.767

We can see that grade 6 students are more likely to be members of the public library.

Therefore, we have found that the students of grade 6 are more likely to be members of the public library.

When there's a letter, it represents a variable. You need to find the value (number) of this variable. This can be done by trying to isolate (put it by itself) the variable. So now, here is how to do it:

1) -2j + 6 = 2j - 8

-2j - 2j = - 8 - 6

-4j/4 = -14/4

j = 14/4

j = 7/2

2) 4h + 6 = 2h - 8

4h - 2h = - 8 - 6

2h/2 = - 14/2

h = -7

3) 9w + 9 = 3w - 15

9w - 3w = - 15 - 9

6w/6 = -24/6

w = -4

4) 45 = -9(e + 8)

45 = -9e - 72

45 + 72 = -9e

117/-9 = e

e = -13

5) 35 = -7t

35/-7 = t

t = -5

6) 12k + 13 = 8k + 33

12k - 8k = 33 - 13

4k/4 = 20/4

k = 5

Once a large pink​ ribbon, the sign of the fight against breast​ cancer, was erected out of pink​ post-it notes on a billboard. If the area of the rectangular billboard covered by the ribbon was approximately 3420 square​ feet, and the width of the billboard was approximately 57 feet, what was the height of this​ billboard?

Answers

Answer:

60 feet

Step-by-step explanation:

The shape of a billboard = Rectangle

Area of a rectangle = Length(Height) × Width

Area = 3420 square feet

Width = 57 feet

Height = Area of the billboard/Width

Height = 3420 ft²/57 ft

Height = 60 feet

Therefore, the height of the billboard is 60 feet

does anyone know the answer to this question.....0.5x + 1.75 = 10

Answers

Answer:

x = 16.5

Step-by-step explanation:

0.5x + 1.75 = 10

Subtract 1.75 from both sides:

0.5x = 8.25

Divide both sides by 0.5

x = 16.5

Check your work!

0.5(16.5) + 1.75 = 10

8.25 + 1.75 = 10

10 = 10

x = 16.5

An airplane can seat up to 175 passengers. The airline has already sold 87 tickets for a flight on the airplane. Which graph represents the solution to the inequality that finds the number of tickets the airline can still sell?​

Answers

Answer:

C

Step-by-step explanation:

The number of tickets the airline still sells will be 88. Then the correct graph is A.

What is inequality?

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

An airplane can seat up to 175 passengers.

The airline has already sold 87 tickets for a flight on the airplane.

Then the graph represents the solution to the inequality that the number of tickets the airline still sells will be

Let x be the number of the ticket which need to sell. Then the inequality equation will be

x + 87 ≤ 175

       x ≤ 175 - 87

       x ≤ 88

Thus, the correct option is A.
