A picnic basket was marked up 95% from an original cost of $9.57. Last Friday, Rosanne bought the picnic basket and paid an additional 8% in sales tax. What was her total cost?

Answers

Answer: $10.60

Step-by-step explanation:

Turn 95% into a decimal then add $9.57, then turn 8% into a decimal then add all of the numbers together.

I'm not sure if this is right, I did it on my own.

The total cost to be paid is $20.15

What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

Original cost = $9.57

Markup= 95%

So, the new cost of the basket

=95/100 x 9.57

=0.95 x 9.57

=$9.0915

Thus, the cost of the basket is

= 9.57+9.0915

=18.66

Also, the sales tax is 8%

=8/100 x 18.66

=0.08 x 18.66

=1.4928

Therefore, the total amount to be paid is

=18.66+1.4928

=$20.15

Jeff bought a bottle of water for $2. He also bought some hot dogs for $3 each. Jeff did not spend more than $14 on the hot dogs and the bottle of water. Witch inequality can be used to find h, the number of hot dogs that jeff could have bought. (If you answer I'll give you a brainilst;))

F. 3h-2<≤4
G. 3h+2≤14
H. 3H-2≥14
J. 3h+2≥14

Answers

Answer:

3H - 2 ≤ 14 I believe.

If i'm wrong forgive me

Answer:

G: 3h+2[tex]\leq \\[/tex]14

Step-by-step explanation:

He could've spent 14 dollars, or less, so the sign is the less than, equal to sign. The 3h represents the cost of hot dogs times the number of hot dogs. The represents the cost of the water bottle. It is addition because he purchased both the water bottle and hot dogs.

In the course of a short race, a car does 50,000 J of work in 7 s. What is the power of the car during the race? (round to the nearest whole number)

Answers

Answer:

Work done is the product of distance and force, it is measured in joules.

Power is the rate of work done given by dividing the work done by time

Power (watts)= workdone (J)/ time (s)

= 50,000J/7 sec

= 7142.857 watts

Therefore, the power of the car during the race was 7142.857 watts

Let’s find the slope of this equation

Slope formula:

(y2-y1/x2-x1)

Plug things in

(-3000-0/20-0)

(-3000/20)

Condense the fraction

Slope = -150 or lowering 150 feet per minute.

Let’s get point slope form, add in some points.

Point slope form:

y - y1 = -150(x - x1)

Plug things in

y - (-3000) = -150(x - 20)

y + 3000 = -150x + 3000

Subtract 3009

y = -150x

Plug in -36000 for y

(-36000) = -150x

Divide by -150

x = 240

You are correct, it took 240 minutes.

This is an isosceles triangle, as indicated by the two lines on two sides (they are equal). One angle is 45 degrees, as indicated. We know that the angles of the two equal sides are equal as well. Knowing that all triangles sum up to 180 degrees, we can subtract 45 from 180 and divide by two to get each equal angle.

Here it is:

180-45=135

135 divided by 2 is 67.5.

This means that the value of x is 67.5 degrees.

To check, we can add all of the sums and it should be 180 degrees.

45+67.5+67.5=180

∴ x= 67.5 degrees

Take what a triangle equal up to them subtract 45

Answer:

Look at the image.

Step-by-step explanation:

0.25(4x - 24) + x = 14

x - 6 + x = 14

2x - 6 = 14

2x - 6 + 6 = 14 + 6

2x = 20

2x ÷ 2 = 20 ÷ 2

x = 10

The goalie on the Iceblades hockey team saves (blocks) 73% of the opponent's shots. With 10 minutes to go, the Iceblades are ahead by one goal, and they will win if the other team does not score.
The other team takes 5 shots in the final 10 minutes. The Iceblades do not score any more goals.
The table shows pairs of random digits. The pairs in each group simulate the 5 shots taken by the opponent.
Answer the questions to estimate the probability that the Iceblades will win the game.

1. The paired digits 00 to 99 represent 100 shots.
Let 00 to 72 = a shot that is saved. Which digits represent a goal scored? Explain.

2. Each group represents the 5 shots taken by the other team. To win the game, the Iceblades cannot let the other team score any goals.
For a group to be a success, how many of the 5 shots does the goalie need to save?

3. Group 1 is a success. Explain why.

4. In this simulation, which groups are successes? How many successes are there in the 10 groups?

5. Estimate the probability the Iceblades will win the game. Give your answer as a percent.
