James is buying a chair that regularly costs $435. Today the chair is on sale for 47% off. If the tax rate is 8.5% , what is the sale price of the chair including tax

Answers

Answer: The sale price of the chair including tax = $221.83

Step-by-step explanation:

Regular price of chair = $435

Discount = 47%

Sales price = 47 % of (Regular price)

= $ 0.47 (435)

= $ 204.45

Tax rate = 8.5% = 0.085

Tax amount = Tax rate × Sales price

= 0.085 × 204.45

= 17.37825≈ $ 17.38

The sale price of the chair including tax = Sales price + Tax amount

= $ ( 204.45+17.38)

= $ 221.83

Hence, the sale price of the chair including tax = $221.83

b) Use the total of the results to estimate the

probability of Ben of hitting the target.

Answers

Answer:

[tex]P(Hits) = 0.70[/tex]

Step-by-step explanation:

Given

[tex]Throws = 120[/tex]

[tex]Hits = 84[/tex]

[tex]Miss = 36[/tex]

See attachment for result

Required

Determine the probability of hitting the target

This calculated using:

[tex]P(Hits) = \frac{n(Hits)}{n(Throws)}\\[/tex]

[tex]P(Hits) = \frac{84}{120}[/tex]

[tex]P(Hits) = 0.70[/tex]

Hence, the probability of hitting the target is 0.70

At a dance, 25% dresses up in a superhero costume, 32% as a scary character, 10% as an entertainer, 15% as a children's movie character, and 16% did not dress up at all. If a total of 250 students attended the dance and 15% of the scary character students were girls, how many boys dressed up as a scary character? ​

Answers

Answer:

68 boys

Step-by-step explanation:

32% of 250 = 80

of 80 scary characters, 15% were girls

80 x .15 = 12 (girls)

80 - 12 = 68 (boys)

There were 220 people who voted at the 6th grade meeting. Sixty percent of the voters are in favor of changing the school mascot. How many people are against changing the mascot? Use numbers and words to explain your answer.

Answers

Step-by-step explanation:

First I had to find 60% of 220.

220 × .60 = 132.

132 people are in favor so I have to subtract that number from 220 to find how many people were against.

220-132 = 88

88 people were against changing the mascot.

Here, we have,

given that,

Barry is 66 inches tall.

we know that,

1 inch is approximately 2.54 centimeters

Since 1 foot = 2.54 centimeters

all we need to do is to multiply 66 with 2.54

What is the height, in units, of the prism?
​

Answers

Answer:

Isolate the variable and simplify.

Step-by-step explanation:

13h = 109.2

h = 109.2 ÷ 13

The sum of two numbers is 46 and their

13

Answer:

B. 13

Step-by-step explanation:

We have two unknown numbers, let's have two variables for these two unknown numbers, X and Y.

"The sum of two numbers is 46 and their difference is 20."

Meaning we have two equations :

X + Y = 46

X - Y = 20

Looking at the last part of "their difference is 20." We can assume X = Y + 20

So substitute the assumed equation into X + Y = 46

(Y + 20) + Y = 46

2y + 20 = 46

Subtract 20 from both sides :

2y = 26

Divide 2 by both sides :

y = 13

There you go.

The first snack is 270 calories for 3 servings, and the second snack is 450 calories How many servings does the snack have to have in order to equivalent to the first snack?

Answers

Answer:

5 servings

Step-by-step explanation:

Given that:

For a particular first snack  to be = 270 calories;

the servings = 3

Then, for the second snack, the calories = 450.

To estimate the servings for the second snack; we need to equate the first snack with the second snack.

Let y be the value of the unknown second snack

Then:

270 calories = 3 servings

450 calories = y servings

y servings = (450 calories × 3 servings) / 270 calories

y servings = 5 servings

Thus; the second snack needs to have 5 servings in order to be equivalent to the first snack
