What Is The Measure Of B?

Answers

Answer 1

Answer: ∠B = 82°

Step-by-step explanation:

To find the measure of B, you have to find the measure of A.

m∠143° + m∠A = 180° because they are a linear pair

m∠A + 143 = 180

Subtract both sides by 143

m∠A = 37

Since you know the measure of angle A, you can find angle B

Angle A, B, and C should add up to 180° as triangles' angles sum up to 180°.

∠B + ∠A + ∠C = 180°

Substitute

∠B + 37 + 61 = 180

∠B + 98 = 180

Subtract 98 from both sides

∠B = 82°

In ASTU, mZS = (6x – 15)°, mZT = (2x − 2)°, and
mZU = (4x – 7)º. What is the value of x?

Answers

Answer:

x = 17

Step-by-step explanation:

all three expressions should be added together and set equal to 180 degrees

6x - 15 + 2x - 2 + 4x - 7 = 180

now combine like terms

12x - 24 = 180

add 24

12x = 204

x = 204/12

x = 17

kazito sold an item for sh 4950 and made a 12 ¹/2profit.what was the cost price of the item?​

Answers

Answer:

[tex]Cost\ Price = 4331.25[/tex]

Step-by-step explanation:

Given

Selling Price = Sh. 4950

Profit = 12.5%

Required

Determine the cost price

Profit is calculated as:

[tex]Profit = \frac{Selling\ Price - Cost\ Price}{Selling\ Price} * 100\%[/tex]

Substitute values for Selling Price and Profit

[tex]12.5\% = \frac{4950 - Cost\ Price}{4950} * 100\%[/tex]

Cross Multiply:

[tex]4950 * 12.5\% = (4950 - Cost\ Price) 100\%[/tex]

[tex]\frac{4950 * 12.5\%}{100\%} = (4950 - Cost\ Price)[/tex]

[tex]618.75 = (4950 - Cost\ Price)[/tex]

Collect Like Terms

[tex]Cost\ Price = 4950 - 618.75[/tex]

[tex]Cost\ Price = 4331.25[/tex]

Hence, the cost price of the item is: Sh. 4331.25

Answers

Answer:

a. 0.57

b. 0.22

c. 0.87

d. 0.9450

Step-by-step explanation:

A.

P(X>=1)

= 0.35 + 0.15 + 0.06 + 0.01

= 0.57

This is the probability of catching one or more fishes.

b.

P(X>=2)

0.15 + 0.06 + 0.01

= 0.22

This is the probability of catching 2 or more fishes.

C.

Compute μ

μ = E(X)

= (0x0.43) + (1x0.35) + (2x0.15) + (3x0.06) + (4x0.01)

= 0+0.35+0.3+0.18+0.04

= 0.87

D.

The standard deviation

Sd = √V(X)

V(X) = E(X²) - (E(X))²

E(X²) = (0²x0.43)+(1²x0.35)+(2²*0.15)+(3²*0.06)+(4²*0.01)

E(X²) = 0.35+0.6+0.54+0.16

= 1.65

V(X) = 1.65 - (0.87)²

= 1.65 - 0.7569

= 0.8931

Sd = √0.8931

= 0.9450

You’re taking an exam in math, and you spend 5 minutes for every 2 questions you answer on the test.(Plz answer! I’m failing and I need to get this correct!)

Answers

Given:

Time spend on every 2 questions = 5 minutes.

To find:

The missing values for the given table.

Solution:

Let x be the number of questions and y be the number of minutes.

We have,

Time spend on every 2 questions = 5 minutes

Time spend on 1 question = [tex]\dfrac{5}{2}=2.5[/tex] minutes

Time spend on x questions = [tex]2.5x[/tex] minutes

Now,

[tex]y=2.5x[/tex]

For x=0,

[tex]y=2.5(0)=0[/tex]

For x=1,

[tex]y=2.5(1)=2.5[/tex]

For x=2,

[tex]y=2.5(2)=5[/tex]

For x=3,

[tex]y=2.5(3)=7.5[/tex]

For x=4,

[tex]y=2.5(4)=10[/tex]
