Oberon makes $13.75 an hour. He gets a 3.5% raise. What is his new hourly salary?

Answers

Answer:

$14.23

Step-by-step explanation:

Multiply the original value by 1.035 to get your answer.

Let x be the initial salary

x=13.75

Let y be the new salary

y=x+x(3.5%)

y=13.75+13.75(0.035)

y=13.75+0.48=14.23

New hourly salary=14.23$

Ben plays basketball 6 times every 3 weeks. At this rate how many times does he play basketball in 10 weeks ?

Answers

Ben will play 18times

Answer:

20 times

Step-by-step explanation:

Let's assign the variable "w" for weeks

6 = 3w

Divide by 2 on both sides

2 = w

That means he plays basketball 2 times every week

For 10 weeks we multiply each side by 10

2 x 10 = 10 x w

20 = 10w

He plays basketball 20 times in 10 weeks.

In the isosceles trapezoid ABCD, find m

Answers

Answer:

answer C

Step-by-step explanation:

Isosceles trapezoids have the property that opposite angles are supplementary.

Here are some needed properties of isosceles trapezoids.

<C and <D are supplementary

<A = <D

<B = <C

<D + <B = 180

<D = 110                         Given

110 + <B = 180               Subtract 110 from both sides..

<B = 70

C

The manager of the Danvers-Hilton Resort Hotel stated that the mean guest bill for a weekend is $600 or less. A member of the hotel's accounting staff noticed that the total charges for guest bills have been increasing in recent months. The accountant will use a sample of future weekend guest bills to test the manager's claim. a. Which form of the hypotheses should be used to test the manager's claim? H 0: less than or equal to $600 H a: greater than $600 b. When H 0 cannot be rejected, can we conclude that the manager's claim is wrong? No c. When H 0 can be rejected, can we conclude that the manager's claim is wrong? Yes

Answers

Answer:

H0 : μ ≤ 600

H1 : μ > 600

B.) NO

C.) YES

Step-by-step explanation:

Here, the null hypothesis is the claim, that mean guest bill is $600 or less ; The alternative will be the opposite of the null which is the counterclaim. This ubstge accountants assertion that guest bill has been increasing

Hence,

H0 : μ ≤ 600

H1 : μ > 600

When the null cannot be rejected, that means there is no sufficient evidence to support the alternative hypothesis, Hence, we stick with the manager's claim

When H0 can be rejected, then there is sufficient evidence to support, the accountant's claim. Thus, we go with the accountant's claim and conclude that the manager is wrong.

How to solve this equation

Answers

Set up an equation for each store by multiplying the cost of the basketball by the number of basketballs bought (b) and add the cost of the hoop:

Hoops House: total = 20b + 200

Baller Basement: total = 15b + 250

Now to solve for b, set the two equations equal to each other:

20b + 200 = 15b + 250

Subtract 15b from both sides:

5b + 200 = 250

Subtract 200 from both sides:

5b = 50

Divide both sides by 5:

B = 10

The answer is 10 basketballs

1. Although a Ferris Wheel is turning at a constant rate, the rate of change of height is
not constant. Explain why. ​

Answers

9514 1404 393

Explanation:

The "speed made good" is the product of the speed and the cosine of the angle between the direction of the speed and the direction of interest. A change in height is accomplished by speed in the vertical direction.

When a spot on the Ferris Wheel is traveling vertically, as at a side position, the angle difference is zero and the cosine is a maximum. All of the vertical speed results in a change in height.

When a spot on the Ferris Wheel is traveling horizontally, as at a top or bottom position, the angle difference from the vertical is 90°, and the cosine of the angle is 0. That is, none of the horizontal speed results in a change in height.

The vertical speed is not constant because the angle of the direction of motion with respect to the vertical is not constant.
