Answer 1

Answer:

m∠AOC = 15°m∠BOC = 15°

Step-by-step explanation:

Given the angle ∠AOB

It is stated that CO is the angle bisector of ∠AOB.

Given that ∠AOB = 30°

As we know that the angle bisector bisects the angle into two equal angles.

Thus, the angle bisector CO bisects the angle ∠AOB into two equal angles, which are:

m∠AOCm∠BOC

as

∠AOB = 30°

Thus, the two formed angles i.e m∠AOC and m∠BOC by the angle bisector would be half of the angle bisector as the angle bisector bisects the angle ∠AOB into two equal angles.

Therefore,

m∠AOC = 15°m∠BOC = 15°

Step-by-step explanation:

Firstly, we need to know the amount in which Z got

That will be 250,000-x-y

= 250,000- 60,000 - 110,000 = 80,000

An employee receives a 2% raise once per year. If the employee's initial salary is $52,400.00, What will the employee's salary be after 16 years?

Answers

The employee will receive a percentage raise after 16 years is $69,168

How to calculate the employee salary after 16 years ?

The first step is to calculate the percentage raise of the salary per year

= 2/100 × 52,400

= 0.02 × 52,400

= 1,048

The next step is to multiply 1,048 by the number of years

= 1048 × 16

= 16,768

The salary after 16 years can be calculated as follows

= 52,400 + 16,768

= 69,168

Hence the employee salary after 16 years is $69,168

Marvin is making lemon bread and pumpkin bread for a school bake sale. he needs 4 and 1/2 cups of flour for the lemon bread and 1 and 1/2 times as much flour for the pumpkin bread. he only has 2 and 1/8 cups of flour left in his pantry, so he buys a new bag from the grocery store. how much flour will marvin use from the new bag? write your answer as a whole number, fraction, or mixed number. simplify any fractions.

Answers

[tex]\frac{73}{8}[/tex] cups or [tex]9\frac{1}{8}[/tex] cups or 9.125 cups of flour will be used from new bag.

Flour required for lemon bread = [tex]4\frac{1}{2}[/tex] cups

Flour required for lemon bread = [tex]\frac{(4*2)+1}{2}[/tex]

Flour required for lemon bread = [tex]\frac{9}{2}[/tex] cups

Flour required for pumpkin bread = [tex]1\frac{1}{2} * \frac{9}{2}[/tex]

Flour required for pumpkin bread = [tex]\frac{(2*2)+1}{2}* \frac{9}{2}[/tex]

Flour required for pumpkin bread = [tex]\frac{5}{2}*\frac{9}{2}[/tex]

Flour required for pumpkin bread = [tex]\frac{45}{4}[/tex] cups

Now, the amount of flour Marvin already has = [tex]2\frac{1}{8}[/tex]

The amount of flour Marvin already has = [tex]\frac{(2*8)+1}{8}[/tex]

The amount of flour Marvin already has =[tex]\frac{17}{8}[/tex] cups

The amount of flour needed from new bag = [tex]\frac{45}{4}-\frac{17}{8}[/tex]

Taking LCM, we get 8

The amount of flour needed from new bag = [tex]\frac{(45*2)-17}{8}[/tex]

The amount of flour needed from new bag = [tex]\frac{90-17}{8}[/tex]

The amount of flour needed from new bag = [tex]\frac{73}{8}[/tex] cups

Hence, the amount of flour that will be used from new bag is [tex]\frac{73}{8}[/tex] cups or [tex]9\frac{1}{8}[/tex] cups or 9.125 cups.

Which equation has no solution?
O l-2x + 81 = 0
O [3x + 61 = 6
o 14x - 2) = -6
O 1-2 - x| = 9

Answers

Answer: |4x-2|=-6

Step-by-step explanation:

This has no solution

The equation that has no solution is | 4x - 2 | = -6.

What is an equation?

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

| -2x + 8 | = 0: This equation has only one solution, which is x = 4. When we take the absolute value of any number, the result is always non-negative (i.e., greater than or equal to zero).

Therefore, the absolute value of -2x + 8 can only be zero if -2x + 8 itself is zero. Solving for x, we get x = 4.

| 3x + 6 | = 6: This equation has two possible solutions, which are x = 0 and x = -4. When we take the absolute value of 3x + 6, the result can be either positive or negative, depending on the value of x.

Therefore, we need to solve two separate equations: 3x + 6 = 6 and 3x + 6 = -6. Solving for x in each case, we get x = 0 and x = -4.

| 4x - 2 | = -6: As I mentioned in my previous answer, this equation has no solutions.

An absolute value cannot be negative or equal to a negative number, so there is no value of x that would make the left-hand side of the equation equal to -6.

| -2 - x | = 9: This equation has two possible solutions, which are x = -11 and x = 7. When we take the absolute value of -2 - x, the result can be either positive or negative, depending on the value of x.

Therefore, we need to solve two separate equations: -2 - x = 9 and -2 - x = -9. Solving for x in each case, we get x = -11 and x = 7.

Landon left his house at time zero and drove to the store, which is 6 blocks away, at a speed of 3 blocks per minute. Then he stopped and went into the store for 7 minutes. From there, he drove in the same direction at a speed of 2 blocks per minute until he got to the bank, which is 4 blocks away from the store. He stopped at the bank for 5 minutes. Then he drove home at a speed of 5 blocks every minute. Make a graph of showing the number of blocks away from home that Landon is xx minutes after he leaves his house, until he gets back home.

Answers

Answer:

Step-by-step explanation:

The route Landon took starting at time t = 0 is

Home ⇒ Store ⇒ Bank ⇒ Home

Let's compute cumulative distances(in terms of blocks) and cumulative time using  Landon's speed and stay at various places in order to plot a graph. (Note: cumulative means total  so far; we add current value to previous total)

The graph will have cumulative time t (in minutes) on the X-axis and cumulative distance d (in terms of blocks) on the Y-axis. We will indicate Landon's position at any time with the coordinates (t, d)

At time t=0 Landon is at home so d = 0
Landon's position at time t=0 is  (0, 0) Home ⇒ Store
Total distance traveled = 6 blocks at a speed of 3 blocks per minute
Time taken to reach store = 6/3 = 2 minutes.
Cumulative time t = 0 + 2  = 2 minutes
Cumulative distance = 0 + 6 = 6 blocks
Landon's position is (2, 6)
Landon stayed at the store for 7 minutes. So between t=2 and t=2+7 distance remains unchanged
Cumulative time = 2 + 7 = 9 minutes
Cumulative distance = 6 + 0 = 6 blocks
Landon's position at t = 9 is (9, 6)
Store ⇒ Bank
Speed was 2 blocks per minute and covered 4 blocks
So time taken = 2 minutes
Cumulative time t = 9 + 2 = 11 minutes
Cumulative distance d = 6 + 4 = 10 blocks.
So Landon's position is (11 , 10)  
Bank Stop : 5 minutes
Cumulative Time t = 11 + 5  16 minutes
Cumulative distance d = 10 + 0 = 10 blocks (distance unchanged)
Landon's position: (16, 10)
Bank ⇒ Home
Total distance covered = 10 blocks at a speed of 5 blocks per minute
Time taken = 10/5 = 2 minutes
Cumulative time t = 16 + 2 = 18 minutes
Distance from home is 0
Landon's position is (18, 0)

which statements describe transformations performed in f (x) = x^2 to create g (x) = 2x^2 + 5? select all that apply.
a. a vertical stretch with a scale factor of .5
b. a translation of 5 units to the right.
c. a translation of 5 units up.
d. a vertical stretch with a scale factor of 2.

Answers

Answer:

The statements describe transformations performed in f(x) to create g(x) are:

a translation of 5 units up ⇒ c

a vertical stretch with a scale factor of 2 ⇒ d

Step-by-step explanation:

If f(x) stretched vertically by a scale factor m, then its image g(x) = m·f(x)If f(x) translated vertically k units, then its image h(x) = f(x) + k

Let us use these rule to solve the question

f(x) = x²

∵ g(x) is created from f(x) by some transformation

g(x) = 2x² + 5

→ Substitute x² by f(x) in g(x)

g(x) = 2f(x) + 5

→ Compare it with the rules above

m = 2 and k = 5

→ That means f(x) is stretched vertically and translated up

f(x) is stretched vertically by scal factor 2

f(x) is translated 5 uints up

The statements describe transformations performed in f(x) to create g(x) are:

a translation of 5 units upa vertical stretch with a scale factor of 2

Lily wants to buy a cow but can't afford the $25 it costs. Later in the year it is at an affordable $15 and Lily can buy it. What percentage of a
discount was on the cow? Please explain :)

Answers

Answer:

There was 60% discount on the cow.

Step-by-step explanation:

Cost of cow = $25Latest price = $15

Discount can be calculated by dividing the latest price by the original price and multiplying by 100.

Thus,

percentage discount = 15/25 × 100

                                   = 0.6 × 100

                                    = 60%

Thus, there was 60% discount on the cow.
