Mark spends $36 at a basketball game. He buys a T-shirt for $22. He then buys a bottle of water for $4 and 2 tacos. How much is each taco?

Answers

Answer:

each taco is $7.

Step-by-step explanation:

In total he spent $36. He bought a shirt for $22 and a bottle of water for $4.

22+4= 26

36-22= 14

14 divided by 2= 7

Answer:

each taco is $5.

Step-by-step explanation:

Let's think about like Mark starts off with $36. Take away $22 for that t-shirt he bought. Now he has $14. He uses $4 for water, now he has $10. The rest of his money is spent on tacos. $10/2 tacos is $5 for each taco. :)

The graph of y = f(x) is shown below. Determine the value of x when f(x) = 2?

Answers

The value of x when f(x) = 2 is 0.

When you replace f(x) with 2 you get y = 2.

Thus, you graph y = 2 and you get the following image below.

A scaled copy with the scale factor being 3/4 it would be smaller because it’s less than one so whenever there is a fraction that’s less than one then the shape would be smaller aswell

Ethan invested $9,500 in an account paying an interest rate of 2 3/4% compounded monthly. Henry invested $9,500 in an account paying an interest rate of 3 3/8% compounded quarterly. After 9 years, how much more money would Henry have in his account than Ethan, to the nearest dollar?

Answers

Answer:

691

Step-by-step explanation:

Henry would have $1,005.94 more than Ethan in his account after 9 years.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

To solve this problem, we can use the formula for compound interest:

[tex]A = P(1 + r/n)^(^n^t^)[/tex]

where A is the amount after t years,

P is the principal

r is the annual interest rate,

n is the number of times the interest is compounded per year, and

t is the time in years.

For Ethan:

P = $9,500, r = 2.75% = 0.0275 (since it is compounded monthly, n = 12), and t = 9

[tex]A = 9,500(1 + 0.0275/12)^(^1^2^\times^9^)[/tex]

= $12,817.84

For Henry:

P = $9,500,

r = 3.375% = 0.03375 (since it is compounded quarterly, n = 4), and

t = 9

[tex]A = 9,500(1 + 0.03375/4)^(^4^\times^9^)[/tex]

= $13,823.78

The difference in the amounts is:

$13,823.78 - $12,817.84 = $1,005.94

Therefore, Henry would have $1,005.94 more than Ethan in his account after 9 years.

#SPJ3

show that the equation x^3 + x - 3 has a solution between 1 and 2

Answers

Answer:

see explanation

Step-by-step explanation:

Evaluate the polynomial at x = 1 and x = 2

x = 1 : 1³ + 1 - 3 = 1 + 1 - 3 = - 1

x = 2 : 2³ + 2 - 3 = 8 + 2 - 3 = 7

Then ( 1, - 1 ) → (2, 7 )

Shows the polynomial goes from y = - 1 to y = + 7

The change in sign indicates the graph crosses the x- axis between 1 and 2

Thus indicating a solution between x = 1 and x = 2

Frank decided to keep track of his sleep using a fitness tracker. He was surprised to
learn that there was 21 minutes of awake time during the seven hours when he was
supposed to be asleep at night. What percentage of the seven hours was Frank awake during the night?
%

Answers

Answer: 5%

Step-by-step explanation:

First and foremost, we need to know that 60 minutes = 1 hour. Therefore,

7 hours = 60 × 7 = 420 minutes.

Number of minutes awake = 21 minutes

Number of minutes supposed to be asleep = 7 hours = 420 minutes

The percentage of the seven hours that Frank was awake during the night will be:

= 21/420 × 100

= 1/20 × 100.

= 5%

A farmer is creating a budget for planting soybeans and wheat. Planting soybeans costs $200 per acre and planting wheat costs $500 per acre. He wants to spend no more than $100,000 planting soybeans and wheat. What is the "multiplier" for soybeans? ​

Answers

Answer:

5 acres < soybeans < 495

2 acres < wheat < 198 acres

Step-by-step explanation:

If farmer plans to plant minimum of soybeans, it should be 5 acres of soybeans costing $1000. The remaining cost of $98,000 will be available for maximum of wheat, i.e., 198 acres of wheat.

Similarly, if we go for minimum possible planting for wheat, it should be 2 acres, and then resulting in 495 acres for soybeans

5 acres < soyabeans < 495

2 acres < wheat < 198 acres  

Answer:

The multiplier for soybeans is 200, which is dollars per acre.

Step-by-step explanation:

5 acres ≤ soybeans ≤ 495 acres (constraint)

2 acres ≤ wheat ≤ 198 acres (constraint)

150w + 125s = 100,000

This would represent 150 acres of wheat and 125 acres of soybeans. The acres of wheat would add up to $75,000 because 150 x 500 = 75,000 and the acres of soybeans would add up to $25,000 because 125 x 200 = 25,000. (example of a solution, there are more possible)
