What Is The Value Of K?M115Y(4k+5)(6k + 10)X

Answers

Answer 1

Answer: 10

Step-by-step explanation:

Answer 2

The value of k is 10.5.

What is meant by angle ?

An angle is a shape created by two rays or lines that meet at the same terminal.

Here,

∠XZY = (4k + 5)°

∠YXZ = (6k + 10)°

The exterior angle M = 115°

Therefore,

∠XYZ = 180 - 115

∠XYZ = 60°

So, we can write that,

∠XZY + ∠YXZ + ∠XYZ = 180°

(4k + 5)° + (6k + 10)° + 60° = 180°

10k + 75° = 180°

Therefore,

k = 105/10

k = 10.5

Hence,

The value of k is 10.5.

What is the equation of a line that passes through (0, 7) and has a slope of -2?

Answers

Answer:

y = -2x + 7

Step-by-step explanation:

We are given the slope so find the y-intercept using slope-intercept form [ y = mx + b ]

y = -2x + b

7 = -2(0) + b

7 = 0 + b

7 = b

Put everything we know/solved for into the original formula.

y = -2x + 7

Kevin bought twelve 8-ounce bottles of water. How many milliliters of water did Kevin buy? (Note: 1 ounce ≈ 30 ml) Thank you for any help I may get! <3

Answers

Given:

Kevin bought twelve 8-ounce bottles of water.

1 ounce ≈ 30 ml

To find:

The quantity of water in milliliters

Solution:

We have,

1 ounce ≈ 30 ml

8 ounce ≈ 8×30 ml

8 ounce ≈ 240 ml

It means, one 8 ounce bottle can hold about 240 milliliters of water.

Total number of bottles = 12

So, the quantity of water Kevin buy in milliliters is

[tex]12\times 240=2880[/tex]

Therefore, Kevin buys 2880 milliliters of water in twelve 8-ounce bottles.

Step-by-step explanation:

4x - 2 and 3x + 6 are alternate angles and congruent, thus

x - 2 = 6 ( add 2 to both sides )

In 1995 the town of Springdale had a population of 2,378. Over the next 20 years the town's population decreased by 12.5%. What was the population of the town in 2015?

Answers

Answer: 165

Step-by-step explanation:

Exponential equation for decay :[tex]A= P(1-r)^t[/tex] , where A is the value after t year, P = initial value.

As per given ,

P= 2378

t= 20 years

r = 12.5% = 0.125

Now ,

[tex]A=2378(1-0.125)^{20}\\\\=2378(0.875)^{20}\\\\= 2378(0.0692087587)\\\\=164.57842\approx 165[/tex]

Hence, the population of the town in 2015 = 165

A lady came to the market to sell eggs . We first customer bought 1/2 of all her eggs and 1/2 of an egg. Her second customer bought 1/2 of all the remaining eggs and 1/2 of an egg. At this point she had sold all her eggs. So how many eggs did the lady have when she came to the market

Answers

Answer:

3 eggs

Step-by-step explanation:

Let the total number of eggs that the woman brought to the market be represented by x

A lady came to the market to sell eggs.

The first customer bought 1/2 of all her eggs and 1/2 of an egg.

x - (1/2x + 1/2) = y

= 1/2x - 1/2= y

y = Amount of eggs left after the first customer left

Her second customer bought 1/2 of all the remaining eggs and 1/2 of an egg.

At this point she had sold all her eggs.

Hence:

y - (1/2y + 1/2) = 0

y - 1/2y - 1/2

Solving for y

y - 1/2y = 1/2

1/2y = 1/2

y/2 = 1/2

Cross Multiply

2y = 2

y = 1

Solving for x

(1/2x - 1/2) = y

y = 1

1/2x - 1/2 = 1

1/2x = 1 + 1/2

x/2 = 3/2

Cross Multiply

2x = 2 × 3

2x = 6

x = 6/2

x => 3 eggs

What are two ways to start solving the equation 4(c - 3)=8? Choose BOTH ways
1. Add 3 to both sides to get 4c = 11

2. Divide both sides by 4 to get c - 3 = 2

3. Use the distributive property to get 4c - 3 = 8

4. Use the distributive property to get 4c - 3 = 8

5. Subtract 4 from both sides to get c - 3 = 4

Answers

Answer

2, i can't find any other solution

Step-by-step explanation:

you divided both sides by 4 you get x - 3 = 2/2 plus 3 = 5 = x

To solve an equation 4(c - 3) = 8 the correct ways are

1. Use the distributive property to get 4c - 12 = 8

2. 2. Divide both sides by 4 to get c - 3 = 2

What is an equation?

Two algebraic expressions having the same value and symbol '=' in between are called an equation.

The two ways to start solving the equation 4(c - 3) = 8 are:

Use the distributive property to get 4c - 12 = 8, then add 12 to both sides to get 4c = 20, and finally divide both sides by 4 to get c = 5.

This method uses the distributive property to simplify the left-hand side of the equation before solving for c.

Divide both sides by 4, and we get,

4(c - 3)/4 = 8/4

c - 3 = 2

c = 5.

Therefore, the two ways are given above.
