Answer:

F) 63

Step-by-step explanation:

Find the original total stories 10 + 8 + 16 + 8 = 42.

Original ratio of Mary's stories to total stories is 8/42 or 4/21.

Then form equation 4/21 = 12/x ; multiply both sides of 4/21 by 3.

4/21 = 12/63

The students need to write 63 stories to keep the ratio of Mary's stories to total stories the same.

Instructions require you to dilute a powder in 3 quarts of water. You only have a container that is marked in liters. How many liters would you use to dilute the powder?

Answers

Answer:

1 quart = .947 L

3 Q = 2.841 L

So you should use 2.841 L to dissolve the powder

One quartz is equal to 32 oz, then 2.88 liters of water are used to dilute the powder.

What is a conversion of units?

The unit conversion deals with the operation to change one form of the unit to another form of unit.

Instructions require you to dilute a powder in 3 quarts of water. You only have a container that is marked in liters.

We know that

1 quartz = 32 oz

3 quartz = 96 oz

Since 30 milliliters per oz

Then

30 milliliters × 96 oz = 2880 milliliters

Since 1000 milliliters per liter, then we have

[tex]\rm \dfrac{2880}{1000}=2.88\ liters[/tex]

2.88 liters are used to dilute the powder.

a exactly one chocolate contains
nuts

b at least one chocolate contains
nuts.
​

Answers

Answer:

3/16??? and 1/16???

Step-by-step explanation:

im so sorry this might be wrong

The probability that a exactly one chocolate contains nuts is 3/16 and probability that at least one chocolate contains nuts is 0.339.

How to calculate probability ?

Probability is calculated by dividing the number of possible outcomes by the total number of possible outcomes. Probability and odds are two distinct concepts. Odds are calculated by dividing the probability of something happening by the probability of it not happening.

When you calculate probability, you are estimating the likelihood of something occurring and representing it with a precise number.

The probability that a exactly one chocolate contains nuts

No of total chocolates = 16 chocolates

No of chocolates contain nuts = 3

The probability that a exactly one chocolate contains nuts = 3/16

Probability that  at least one chocolate contains nuts is

P(at least one contains nut) = 1 – P(given contains no nuts )^n

P(at least one contains nut) = 1 – (0.8125)^2

P(at least one contains nut) = 0.339

Probability that  at least one chocolate contains nuts = 0.339

Kevin can paint a small room in 18 hours. Kevin and Caleb together can paint the same room in 15 hours.
How long would it take for Caleb to paint the room alone?

Answers

Answer:

90 hours

Step-by-step explanation:

The computation of the time taken for Caleb to paint the room alone is given below:

Given that

Kevin paint a small room in 18 hours

And, kevin & caleb together paint the same room in 15 hours

So, time taken for Caleb to paint the room alone is

Let us assume the same be x

Kevin time taken + caleb time taken = total time taken

[tex]\frac{1}{18} + \frac{1}{x} = \frac{1}{15}\\\\ \frac{1}{x} = \frac{1}{15} - \frac{1}{18}\\\\ \frac{1}{x} = \frac{6-5}{90} \\\\ \frac{1}{x} = \frac{1}{90}[/tex]

x = 90 hours

m(QS) = 52°

m(PD) = 152°

Step-by-step explanation:

Recall: Angle formed by two secants outside a circle = ½(the difference of the intercepted arcs)

Thus:

m<R = ½[m(PD) - m(QS)]

50° = ½[(12x + 8) - (4x + 4)] => substitution

Solve for x

Multiply both sides by 2

2*50 = (12x + 8) - (4x + 4)

100 = (12x + 8) - (4x + 4)

100 = 12x + 8 - 4x - 4 (distributive property)

Add like terms

100 = 8x + 4

100 - 4 = 8x

96 = 8x

96/8 = x

12 = x

x = 12

✔️m(QS) = 4x + 4 = 4(12) + 4 = 52°

✔️m(PD) = 12x + 8 = 12(12) + 8 = 152°

The number of light bulbs produced by a company can be modeled by the expression

purchasing the light bulbs is represented by 5x–3. Which is the expression representing the average number
of light bulbs purchased per company?

Answers

Answer:

Expression is 3x² + 5x - 17

Step-by-step explanation:

We are told the number of lights produced by a company is;

Number of lights = 15x^3 + 16x^2 – 100x + 51

Also, number of companies that purchased the light bulbs is 5x - 3.

Thus;

The average number of bulbs purchased per company = (15x^3 + 16x^2 – 100x + 51)/(5x - 3)

if each quadrilateral below is a square, find the missing measures.

Answers

vu=15 su=square root 450 TV= square root 450 SW= squareroot 450/2

We want to find the missing measures for the given square.

VU = 15TV = 21.2SU = 21.2SW = 10.6

Working with squares.

We know that squares have the same length in all of their 4 sides, with that in mind we can see that:

TS = TU = UV = SV = 15

Then we can already complete:

VU = 15

Now we need the two diagonals, SU and TV.

The diagonal for a square of side length s is:

diagonal = (√2)s

Then the diagonals for our square are:

TV = SU = (√2)*15 = 21.2

And SW is half of the diagonal, so we have:

SW = 21.2/2 = 10.6

Answers

Answer:

225 students

Step-by-step explanation:

Total number of students = 900 students

percent that bring lunch to school everyday = 25%

Number of student that bring lunch to school = 25% of 900

Number of student that bring lunch to school = 0.25 * 900

Number of student that bring lunch to school = 225

Hence 225 students bring lunch to school everyday

Answers

Let f(x) = y

y = 2^x

x = 2^y

Solve for y.

ln x = ln(2^y)

ln x = y ln 2

ln x/ln 2 = y

Replace y with f^(-1) x.

f^(-1) x = ln x/ln 2

We now know f(x) and f^(-1) x.
