Reed has made 78 of 90 attempted free
throws last season. How many
consecutive free throws must he make to
bring his free throw percentage to 90%?

Answers

Answer: 81 consecutive free throws

Step-by-step explanation: Since 78 of 90 attempted free throws equals to 88.89%, then try adding 3 to 78, (78 + 3) which equals to 81. If you convert 81/90 to a percentage, you get 90%. So your final result or answer is 81 consecutive free throws.

Tip: To convert a fraction to a percentage, divide the denominator by the numerator and you should get a decimal quotient. Lastly, just add a percentage sign.

The average temperature for the months of September to December in Medicine Hat, Alberta, one year were 15⁰C, 1⁰C, and -8⁰C. What was the average temperature for the four months?

Answers

Answer:

2.66⁰C or roughly 3⁰C

Step-by-step explanation:

We are missing one value in this question but can solve this problem using the same process. Since we are given the average temperatures of each month, to find the average temperature of all the four months combined we would simply need to add these provided averages and then divide by the total number of months. Since we are missing one value here, in this scenario we would only add the three values and divide by 3.

(15 + 1 + (-8)) / 3 = x

8 / 3 = x

2.66 = x

So the average temperature is 2.66⁰C or roughly 3⁰C

The function f(x)=223(1.09)^x represents the number of specialty items produced at Iron Man’s old factory x weeks after a change in management. The graph represents the number of specialty items produced at the new factory during the same time period.



During Week 0, how many more specialty items were produced at the old factory than at the new factory? Explain.
Find and compare the growth rates in the weekly number of specialty items produced at each factory. Show your work.
When does the weekly number of specialty items produced at the new factory exceed the weekly number of specialty items produced at the old factory? Explain.

Answers

Answer:

a. 33

b. So we see that at the start of 3rd week, the new factory begins to exceed old production.

Step-by-step explanation:

(a)w = 0

Old factory: p(x)=223(1.09)^x Plug in 0

p(0)= 223(1.09)^(0)

When a number has an exponent of 0, the number becomes 1

p(0) = 223(1)

p(0) = 223

New factory: w = 0, p(0) or y = 190         (0,190)

223 - 190 = 33

During Week 0, 33 more specialty items were produced at the old factory than at the new factory.

(b) i don't know sorry

(c)

The old production tabulated:

w P(w) New

0 223 190

1 243 220

2 265 252

3 289 290

4 315 337

5 343 380

6 374 440

7 408 505

So we see that at the start of 3rd week, the new factory begins to exceed old production.

i hope this helped people in the future.

During week 0 the old factory produced 33 more items than at the new factory.

The weekly number of specialty items produced at the new factory exceed the weekly number of specialty items produced at the old factory at week 4.

What is a function?

A function is defined as a relation between a set of inputs having one output each. A function is a relationship between inputs where each input is related to exactly one output. Every function has a domain or range.

According to the given problem,

Specialty items produced at the old factory at week 0,

Given function = [tex]223(1.09)^{x}[/tex]

When x = 0,

f(x) = [tex]223(1.09)^{0}[/tex]

     = 223

Specialty items produced at the new factory during 0 = 190

Old factory exceeded the production by:

⇒ ( 223 -  190 )

= 33 specialty items.

Comparing the growth rates of weekly number of specialty items at each factory,

For week 0,

Old factory = 223

New factory = 190

Growth rate = [tex]\frac{223-190}{190}*100[/tex]

                    ≈ 17%

For week 1,

Old factory = 243

New factory = 220

Growth rate = [tex]\frac{243.07-220}{220}*100[/tex]

                    ≈ 10%

For week 2,

Old factory = 265

New factory = 252

Growth rate = [tex]\frac{264.95-252}{252}*100[/tex]

                    ≈ 5%

For week 3,

Old factory = 289

New factory = 290

Growth rate = [tex]\frac{290 -288.79}{288,79}*100[/tex]

                    ≈ 0.41%

For week 4,

Old factory = 325

New factory = 337

Growth rate = [tex]\frac{337-324.78}{324.78}*100[/tex]

                    ≈ 3%

For week 5,

Old factory = 343

New factory = 380

Growth rate = [tex]\frac{380-343.11}{343.11} *100[/tex]

                    ≈ 13%

For week 6,

Old factory = 374

New factory = 440

Growth rate = [tex]\frac{440-374}{374} *100[/tex]

                    ≈ 18%

For week 7,

Old factory = 408

New factory = 505

Growth rate = [tex]\frac{505-408}{408} *100[/tex]

                   ≈ 23%

At week 3, the production at new factory exceeds the production of the old factory.

For old factory,

⇒ f(x) = [tex]223(1.09)^{x}[/tex]

          = [tex]223(1.09)^{3}[/tex]

          = 289

For new factory at week 3,

Production = 290 items.

Hence, we can conclude, during week 0 the old factory produced 33 more items than at the new factory and the weekly number of specialty items produced at the new factory exceed the weekly number of specialty items produced at the old factory at week 4.

What is the slope-intercept equation for the line below? (5, 4) (0, 2) 6 +
O A. y=x+2
O B. y=-x+2
O C. y=-x+2 O 2/
D. y=x+2​

Answers

Answer:

The answer is D y=2/5x + 2

Step-by-step explanation:

I find the the slope first by using the slope formula y2 - y1/x2 - x1

Then, I use the slope-intercept formula to find the y-intercept

4 = 2/5(5) + b

4 = 10/5 + b

4 = 2 + b

4 - 2 = 2 - 2 + b

2 = b

So u get:

y=2/5x + 2

Answers

Answer:

30

Step-by-step explanation:

Well we know the first angle is 90 degrees, which means we have 90 degrees left to work with. Then, the top angle would be 60 degrees, because there is a straight line (which of course has to equal 180), so 180-120 = 60. Now, 90-60=30!

Answer:

k = 30

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

120° is an exterior angle of the triangle, thus

k + 90 = 120 ( subtract 90 from both sides )

k = 30

Cecelia brought a stock five years ago for $3,400. She sold it this year for $4,100. How much capital gain will she be required to pay taxes on?

Answers

Given:

Purchasing price of stock = $3400

Selling price of stock = $4100

To find:

The capital gain.

Solution:

We know that, assets increase their values with respect to time and capital gain is the profit earned on sale of those assets.

Capital gain = Selling price - Purchasing price

                    = $4100 - $3400

                    = $700

Therefore, the capital gain is $700.

(To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.)

Your recipe must meet the following contest guidelines:1. It must have at least five different ingredients.2. The amount of each ingredient should be represented by a different mixed number.3. The recipe must make exactly 10 cups of trail mix.After you write your recipe, complete the following for your contest entry: Prove that your recipe makes exactly 10 cups.

Note: Depending on the fractions that you chosefor your ingredient amounts, it may not be possible to create each exact amount using only 13 and 14 measuring cups. If you need to, you can round your ingredient amounts using benchmarks and then explain how you would estimate that amount. For example, if you need 74 cup of an ingredient, 74cup is slightly more than 12 cup. You could fill up your 14 measuring cup twice to make 12 cup of that ingredient, and then add just a tiny bit more to estimate 74 cup.
