Answer:

192 hours per day / 8 hours per person per day = 24 people

Step-by-step explanation:

Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:

720 person-days x 8 hours = 5,760 hours

To complete the project in 30 days, the total number of hours needed per day is:

5,760 hours / 30 days = 192 hours per day

Step-by-step explanation:

Answer:

H. 95°

Step-by-step explanation:

m∠BGC is 10° smaller than m∠CGD, which means that m∠BGC is x° - 10°

m∠DGE is 25° more than m∠EGF, which means that m∠DGE is x° + 25°

The sum of all angles in a placement like this will always equal 360°

So we put all the measures of all angles on one side of thee equation and set it equal to 360*

x° + x° - 10° + 2x° + 25° + 2x° + 3x° + 30° = 360°

After combining like terms we get 9x° + 45° = 360°

After some algebra we get x = 35°

Now at the start we said that m∠DGE is x + 25°

Plug in 35° for x and we get 35° + 25°

The final answer is m∠DGE = 95°

Answer:

a. 20 - (4 ⋅ 3)

Step-by-step explanation:

PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

Please note that multiplication 4 ⋅ 3 will happen before the subtraction -

If we add parentheses, we introduce a new "order". But if the parentheses are around the first operation we perform, the order stays the same!

This means that answer a. must be correct.

We verify:

20 − 4 ⋅ 3 = 20 - 12 = 8

a. 20 − (4 ⋅ 3) = 20 - 12 = 8

b. (20 − 4) ⋅ 3 = 16 ⋅ 3 = 48

c. 20 + 4 − 3 = 21

d. 20 ⋅ 4 − 3 = 80 - 3 = 77

Answer: A: 20 - (4 x 3)

Step-by-step explanation:

In the end, the final answer is 8, so we need to see which one of these options give us 8. As seen, we first must solve the multiplication, and the first option, A, solves the multiplication first because it is in parenthesis, which gives us 8, so the correct answer is A.

Answer:

25.685 square feet.

Step-by-step explanation:

Circumference = 2 * π * radius

From this, we can derive the formula for the radius:

radius = Circumference / (2 * π)

Let's substitute the value of the circumference and calculate the approximate radius:

radius = 18 / (2 * π)

radius ≈ 18 / (2 * 3.14159)

radius ≈ 2.865 feet

Now that we have the approximate radius, we can calculate the area:

Area ≈ π * radius²

Area ≈ 3.14159 * (2.865)²

Area ≈ 3.14159 * 8.193225

Area ≈ 25.685 square feet

Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

Step-by-step explanation:

2x + y - 8 =0

- 2x from both sides

Y - 8 = -2x

Then add 8 to both sides

Y = -2x + 8

The second one = -1/2x + 4 when its in slope intercept form

And the third one = y = 2x + 2

So it’s the first equation that ve slope of -2 and y intercept of 8

The probability of choosing a green shirt is 20%=1/5=.2

Step-by-step explanation:

find the total amount = 10

Find the total of question (probability of choosing green) = 2

set as a fraction:

Numerator = amount needed (2)

Denominator = all things/objects involved (10)

PS*

With probability there is a good chance the answer is going to be less than 1 or 100%, knowing that can help to tell which number goes in what place of the fraction

ex:

10/2=5=500% (this can't be the answer)

So Flip it 2/10=.2=20% (This seems more of a reasonable answer)

Answer:

3/4

Step-by-step explanation:

Since (p, r) lies on the line y = x + b,

we have,

r = p + b -----eq(1)

Since (2p, 5r) lies on the line y = 2x + b,

we have,

5r = 2(2p) + b -----eq(2)

Sub the value of r from eq(1) in eq(2),

5(p + b) = 4p + b

⇒ 5p + 5b = 4p + b

⇒ 5b - b = 4p - 5p

⇒ 4b = -p

⇒ b = -p/4

sub in eq(1)

r = p + (-p/4)

= p - p/4

= 3p/4

⇒ r = 3p/4

⇒ r/p = 3/4

Answer:

3/4

Step-by-step explanation:

We have two lines:

r = p + b     eq(1)

5r = 4p + b   eq(2)

eq(2) - eq(1)

4r = 3p

dividing by 4p

r/p = 3/4

Answer:

320 pounds of 55% raisins trail mix

480 pounds of 30% raisins trail mix

Step-by-step explanation:

Sorry, I can’t write how I got the answer. We just did it in class and decided to help... (Btw, sorry if I’m too late)

The store manager mixed 320 pounds of 55% raisins trail mix and 480 pounds of 30% raisins trail mix.

Given that,

A store manager combines a trail mix that is 30% raisins with a trail mix that is 55% raisins.

He makes 800lb of trail mix that is 40% raisins.

We have to determine,

How many pounds of each trail mix does the manager use?

According to the question,

Let, x = pounds of trail mix 30% raisins

y = pounds of trail mix 55% raisins

The distributor wants to make 800 pounds of trail mix, thus:

x + y = 800  

The mix must be 40% raisings as a combination of x and y, thus:

30x + 55y = 40 × 800

30x + 55y = 32,000

Divided by 5 the equation

6x + 11y = 6400

Solving both the equation

\(x + y = 800\\\\x = 800 -y\\\)

Substitute the value of x in equation 2,

\(6x + 11y = 6400\\\\6 (800-y) + 11y = 6400\\\\4800 - 6y +11y = 6400\\\\5y = 6400-4800\\\\5y = 1600\\\\y = \dfarc{1600}{5}\\\\y = 320\)

Substitute the value of x in equation 1

\(x + y = 800\\\\x + - 800 -y\\\\x = 800-320\\\\x = 480\)

Hence, The store manager mixed 320 pounds of 55% raisins trail mix and 480 pounds of 30% raisins trail mix.

Answer:

It's the first one

Step-by-step explanation:

Answer:

Mean = 33.7

Median = 34.5

Mode = 34

Range = 33

After adding 26....

mean decreases by 0.7

median decreases by 0.5

mode is 34

range is 33

Step-by-step explanation:

mean = sum of all the data values/number of data values

= (18 + 19 + 20  + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7

To find median arrange the values in increasing order, find the mid value

If the number of data points is even, find the average of the mid 2 data values

Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51

Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5

The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once

Mode = 34

The range is highest - lowest = 51 - 18 = 33

After we add 26, we get the following data set arranged

18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51

we can calculate the stats using the same technique as above

We get the following values

mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33  

median = 34

mode = 34

range = 51-18 = 33

To find the decrease in mean and median subtract from the first set of values

\(\frac{16}{27}\)

Step-by-step explanation:

From the table, we notice that the total number of students is:

\(3+10+8+6=27\)

Then, along the second column of the table, we notice that the number of students who do not have a brother is:

\(10+6=16\)

So, the probability that a randomly chosen student does not have a brother is:

\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)
