If there are 68.8 letters to be mailed if 3 children have to mail them how much does each person have to mail?

Answer:

3/7 bags of flour

Step-by-step explanation:

Things we know:

Carmen uses 2/7 bag of flour to make 1/2 of a batch

To make 1 batch she will use :

2/7 flour/1/2 batch = x flour/1batch

2/7 = 1/2x

1/7 = x

We need 1/7 flour to make 1 batch of cookie

If 1 batch uses 1/7 of the flour then 3 batchs will need:

1/7 flour/1batch = x flour/3 batch

1/7 * 3 = x

3/7 = x

Therefore we need 3/7 flour to make 3 batches of cookies.

Option C, 1/35

Step-by-step explanation:

Given

Proportion of town that has blue eyes = 1/5 = 0.2

Proportion of town that has brown eyes = 1/7

The probability of choosing either a blue eye or a brown eye person is

Probability of blue eye individual * Probability of brown eye individual

= 1/5 * 1/7 = 1/35

Hence, option C is correct

Answer:

Hence 173.75 pounds of raw potatoes are needed for 500 servings.

Step-by-step explanation:

The edible yield is 72 % means  4 oz in one serving is 72 %

Using ratios to solve

Oz           %

4             72

x             100

Using the cross product rule

x= 400/72= 5.56 oz

1 serving has 5.56 oz of raw potatoes

500 serving must have 5.56 *500= 2780 oz of raw potatoes

but 1 0z = 0.0625 pounds

As we need to calculate the pounds we will multiply it with 0.0625

Therefore

2780*0.0625= 173.75 pounds

Hence 173.75 pounds of raw potatoes are needed for 500 servings.

Answer:

7.5

Step-by-step explanation:

The values 15ft, 13ft and x are the sides of a right triangle;

According to pythagoras theorem;

15² = 13²+x²

x² = 15² - 13²

x² = 225 -169

x² = 56

x = √56

x = 7.48

Hence the value of x to the nearest tenth is 7.5 to the nearest tenth

Answer(s):

[tex]\displaystyle y = 4cos\:(2x - \frac{\pi}{2}) - 1 \\ y = 4sin\:2x - 1[/tex]

Explanation:

[tex]\displaystyle y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow -1 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{\frac{\pi}{4}} \hookrightarrow \frac{\frac{\pi}{2}}{2} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{\pi} \hookrightarrow \frac{2}{2}\pi \\ Amplitude \hookrightarrow 4[/tex]

OR

[tex]\displaystyle y = Asin(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow -1 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{\pi} \hookrightarrow \frac{2}{2}\pi \\ Amplitude \hookrightarrow 4[/tex]

You will need the above information to help you interpret the graph. First off, keep in mind that although this looks EXACTLY like the sine graph, if you plan on writing your equation as a function of cosine, then there WILL be a horisontal shift, meaning that a C-term will be involved. As you can see, the photograph on the right displays the trigonometric graph of [tex]\displaystyle y = 4cos\:2x - 1,[/tex] in which you need to replase "sine" with "cosine", then figure out the appropriate C-term that will make the graph horisontally shift and map onto the sine graph [photograph on the left], accourding to the horisontal shift formula above. Also keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must be careful with your calculations. So, between the two photographs, we can tell that the cosine graph [photograph on the right] is shifted [tex]\displaystyle \frac{\pi}{4}\:unit[/tex] to the left, which means that in order to match the sine graph [photograph on the left], we need to shift the graph FORWARD [tex]\displaystyle \frac{\pi}{4}\:unit,[/tex] which means the C-term will be positive, and perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{\frac{\pi}{4}} = \frac{\frac{\pi}{2}}{2}.[/tex] So, the cosine graph of the sine graph, accourding to the horisontal shift, is [tex]\displaystyle y = 2cos\:(2x - \frac{\pi}{2}) - 1.[/tex] Now, with all that being said, in this case, sinse you ONLY have a graph to wourk with, you MUST figure the period out by using wavelengths. So, looking at where the graph hits [tex]\displaystyle [-\frac{\pi}{4}, -5],[/tex] from there to [tex]\displaystyle [\frac{3}{4}\pi, -5],[/tex] they are obviously [tex]\displaystyle \pi\:units[/tex] apart, telling you that the period of the graph is [tex]\displaystyle \pi.[/tex] Now, the amplitude is obvious to figure out because it is the A-term, but of cource, if you want to be certain it is the amplitude, look at the graph to see how low and high each crest extends beyond the midline. The midline is the centre of your graph, also known as the vertical shift, which in this case the centre is at [tex]\displaystyle y = -1,[/tex] in which each crest is extended four units beyond the midline, hence, your amplitude. So, no matter how far the graph shifts vertically, the midline will ALWAYS follow.

Answer:

Step-by-step explanation:

A correct answer can only be obtained from a complete question.

A rotation is not always about the origin, but in the absence of information, this will be assumed.

Rotating to the right is assumed to mean rotated from the second towards the first quadrant about the origin.

Rotating any shape about the origin by 360° will always return to the original (starting) position, so the final coordinates will be (-8,2) (-8,8) (-4,2).

The theoretical probability of scoring 10 points upon pressing a button = 3 / 5

The expected number of times 10 points is scored if button is pressed 10 times :

This will be ;

(Number of times button is pressed * theoretical probability of scoring 10 when button is pressed)

(10 * 3 / 5)

= 30 / 5

= 6 times

Answer:

p = 43

Step-by-step explanation:

Here, we have it that;

(x^22) * (x^7)^3 = x^p

From law of indices

(y^a)^b = y^ab

and also;

y^a * y^b = y^(a + b)

applying these, we have it that;

(x^7)^3 = x^(7* 3) = x^21

Thus, we have it that;

x^22 * x^21 = x^(22 + 21) = x^43

So we have it that the value of p is 43

Well, split it into 3 shapes

21 x 10 = 210

3 x 6 = 18

2 x 6 = 12

210 + 18 + 12 = 240 square cm

Answer: 36.576

Step-by-step explanation: The question is asking you to convert 120ft to meters

So if 94ft= 28.65 meters, then 120ft= 36.576 Meters

The length of a tennis court will be;

⇒ 36.57 meters

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The length of a basketball court = 94 feet

Which is approximately = 28.65 meters

Now,

Since, The length of a basketball court = 94 feet

Which is approximately = 28.65 meters

And, The length of a tennis court = 120 feet

So, The length of a tennis court in meters = x

⇒ x = 28.65 × 120 / 94

⇒ x = 36.57 meters

Thus, The length of a tennis court in meters = 36.57 meters

If the population of wolves is increasing, then the function will represent exponential growth. So the number inside the parentheses must be greater than 1. That narrows it down to the last 2. But it's exponential growth, so it includes an exponent. D doesn't have an exponent, so you're left with C :)

Step-by-step explanation:

Answer:I'm going to illustrate by converting 4325 to base 8. I an going to do it in two steps. First convert 4325 to base 10 and then convert this base 10 number to base 8.

Converting 4325 to base 10 just requires remembering what base 5 means.

4325 = 4 × 52 + 3 × 5 + 2 = 4 × 25 + 15 + 2 = 117.

To put 117 into base 8 imagine you have 117 CDs. Put them is stacks of 8 disks each. You get 14 stacks of 8 disks with 5 remaining (that is 117 ÷ 8 = 14 with a remainder of 5). Now take the 14 stacks and put them in groups of 8. You get 1 group of 8 stacks and 6 stacks remaining ((that is 14 ÷ 8 = 1 with a remainder of 6). Thus you have

1 group of 8 stacks (1 × 8 × 8 disks)

6 stacks (6 × 8 disks) and

5 individual disks.

Hence 117 = 1 × 82 + 6 × 81 + 5 = 1658

Here, more compactly is what I did

117 ÷ 8 = 14, remainder of 5

14 ÷ 8 = 1, remainder 6

1 ÷ 8 = 0, remainder 1

Read the remainders from bottom to top, 1658

Answer:

The other point is (-8, 2)

Step-by-step explanation:

A general quadratic equation is something like:

f(x) = a*x^2 + b*x + c

Where a, b, and c are real numbers.

If the function has an axis of symmetry at x₀, this means that:

f(x₀ + x) = f(x₀ - x)

for all values of x.

In this case we have:

x₀ = -1

Then:

f(-1 + x) = f(-1 - x)

Now we know that the point (6, 2) is a solution of the quadratic equation

This means that f(6) = 2

If we write 6 = -1 + x

We can solve this for x to get:

6 = -1 + x

6 + 1 = x = 7

Then we will have:

2 = f(6) = f(-1 + 7) = f(-1 - 7) = f(-8)

Then:

f(-8) = 2

sThis means that the other point on the quadratic eqation is (-8, 2)
