Which problem solving strategy would be best to solve this problem?

Brandon went to the store and spent $2.50 on pencils. He spend half of what he had left on a notebook and paper. When he got home he had $5.00 left. How much money did Brandon have before going to the store?

A) make a table, chart or list
B) work backwards
C) use a formula
D) look for a pattern

Answers

Answer 1

Answer:

B) work backwards.

Step-by-step explanation:

Since they are asking for how much money he had at first and they displayed how much he spent without telling the amount of money at the start of the question, this is definitely a backwards question. For working backwards, you will need to do workings the opposite as what they said in the question.

The number of student athletes at a high school is 475 and is increasing at a rate of 4.8% per year. Use an exponential function to find the number of student athletes after 9 years.

please show your work!!!

Answers

Answer:

475 × 1.48^9 or 16182

Step-by-step explanation:

We start with 475. Then to find the number of students after 1 year we mult 475 by 1.48 (48% + 1 because we're increasing in students). But, to get it after 9 years, we raise that 1.48 to the power of 9 which is equal to 1.48 * 1.48 * 1.48 and so on 9 times. This leads us to our final equation of 475 * 1.48^9 or roughly 16,182

The graph below shows a company's profit f(x), in dollars, depending on the price of pencils x, in dollars, sold by the company:

Graph of quadratic function f of x having x intercepts at ordered pairs negative 0, 0 and 10, 0. The vertex is at 5, 160.

Part A: What is an approximate average rate of change of the graph from x = 2 to x = 5, and what does this rate represent? (3 points)

Part B: Describe the constraints of the domain. (3 points)

Answers

Answer:

A. The maximum represents the most amount of pencil price in dollars sold for the most amount of profit and the x-intercepts represent the profit when it is. The intervals at where the function increases represents a bigger profit for a price, whereas a decreasing interval represents a lower profit for a price.

Step-by-step explanation:

my answer for my test

The average rate of a function is 20 and for every $1 increase in the price of its pencils, the company's profit climbs by $20 on average.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

Average rate of a function:

= (160-100)/5-2

= 20

For every $1 increase in the price of its pencils, the company's profit climbs by $20 on average.

Because prices are rarely negative, the domain is most likely confined to 0≤x. The price may be set so high that it yields a loss, but that is not a viable option. As a result, x ≤10 is the upper limit of the sensible domain.

Thus, the average rate of a function is 20 and for every $1 increase in the price of its pencils, the company's profit climbs by $20 on average.

In triangle ABC, the measure of angle ABC is 51°
and ACB is a right angle. What is the measure of
angle BAC in degrees?

Answers

Answer:

39 degrees

Step-by-step explanation:

The sum of angle in the triangle ABC is a80 degrees

m<ACB + <BAC + <ABC =1 80

90 + <BAC + 51 = 180

141 + m<BAC = 180

m<BAC = 180-141

m<BAC = 39 degrees

Hence the measure of m<BAC is 39 degrees

Swim flippers are helpful for scuba

$15 per day, plus 8% tax. How
much will it cost, including tax, to
rent them for three days?

Answers

Answer:

The answer would be $48.60.

Step-by-step explanation:

Some people could probably answer it better but here's my way: When you have a percentage of something you bring it to the decimal. 8% would be 0.08. We take this and multiply it by the cost: 0.08 times 15, giving us $1.2 per $15 dollars spent. 1.2 times the 3 days would be 3.6 and 15 times 3 is 45 together this would give you the grand total of $48.60.

Multiply that by the cost of the PlayStation five, and that is how much tax you pay.

Find the total surface area of this cylinder.
Give your answer to 1 decimal place.
7 cm
15 cm

Answers

Answer:

For the first figure :

Cylinder :

Radius =7cm

height = 15cm

Total Surface Area:

2 \times \pi \times r(h + r)2×π×r(h+r)

= 2×22/7×7 (15+7)

= 22×44

= 968 cm sq.or 9.68m sq.

For the second figure :

Diameter = 24cm (radius= 24/2= 12cm)

•Height = 18 cm

Total Surface area:

2 \times \pi \times r(h + r)2×π×r(h+r)

= 2×22/7×12 (18+12)

= 2×22/7×12 (30)

= 2×22×12×5

= 2640 cm. sq or 26.4 m.sq

The total surface area of this cylinder is 967.1cm²

Surface area of a cylinder.

The formula for calculating the total surface area of a cylinder is expressed as:

TSA = 2πr(r+h)

Given the following

radius r = 7cm

Height h =15cm

Substitute

TSA = 2π(7)(7+15)

TSA = 14π(22)

TSA=967.1 cm²

The total surface area of this cylinder is 967.1cm²

The sum of 5 consecutive even numbers is 100 ples help :/

Answers

Consecutive even numbers are numbers that go in order, such as 1,2,3,4,5.

There are 5 even numbers.

They would be x, x+2, x+4, x+6, and x+8 (you add 2 each time so they are even).

Now when adding all these numbers, you get 100.

So there's your equation.

x+x+2+x+4+x+6+x+8=100

Add like terms.

5x+20=100

Solve for x.

5x=80

x=16

So the first number is 16.

The second is 18.

Third is 20.

Fourth, 22.

And fifth, 24.

You can add them to see if you are correct.

16+18+20+22+24=100

The numbers are 16,18,20,22, and 24.

.5333333 repeating as a fraction

Answers

8/15 i think but you might want to divide it to check

Answer:

The answer is 8/10

Step-by-step explanation:

When you convert a decimal into a fraction especially a repeating decimal it could be a little complicated but here is what you had to do to find that answer

Step 1: Let x equal the decimal number

Which is x = 0.533333

And with 1 digit in the repeating decimal group create a second equation by multiplying both sides by 10^1 = 10

Step 2:

10x = 0.5333333

Now subtract equation 1 from equation 2

which is

10x = 5.333333

x = 0.5333333

--------------------------

9x - 4.8

We get

9x - 4.8

Step 3: Solve for x

X = 4.8/9

Multiply to eliminate 1 decimal place.

Here you multiply top and bottom by 1 10's

= 10^1 = 10

4.8/9 x 10/10 = 48/90

Step 4: Find the Greatest Common Factor (GCF) of 48 and 90,

if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 6,

48 ÷ 6/90 ÷ 6 = 8/15

Step 5: Therefore

X = 8/15

And in conclusion

0.5333333 = 8/15

So 8/15 is the answer
