Answer:

with what?

Step-by-step explanation:

Answer:

With what? no equation or question is shown

Step-by-step explanation:

it is A. 0.25x - 6.50

You use distributed property first so the equation will be 3x - 1 - 2.75x - 5.50

Then you combine like terms so 3x - 2.75 will equal 0.25x

The subtraction symbol will stick with 1 making it -1 so the second part will be -1 - 5.50 will equal 6.50

And finally, the expression will be 0.25x - 6.50

Answer:

photo 2:

a. interior angles of a triangle

b. vertical angles

c. complementary angles

d. supplementary angles

photo 3:

a. 82

b. 82

photo 4:

a. 51

b. 129

photo 5: x = 60

Step-by-step explanation:

The interior angles of a triangle are the angles that are inside the triangle and are formed by the intersection of two sides of the triangle. In a triangle, there are always three interior angles.

The sum of the interior angles of a triangle is always 180 degrees. This is because the interior angles of a triangle are supplementary, meaning that they add up to 180 degrees.

Vertical angles are two angles that are opposite each other and are formed by two intersecting lines. The lines that intersect to form the vertical angles are called "arms" of the angles.

Vertical angles are always congruent, which means that they have the same measure

Complementary angles are two angles whose measures add up to 90 degrees. In other words, if two angles are complementary, then one angle is the complement of the other.

Supplementary angles are two angles whose measures add up to 180 degrees. In other words, if two angles are supplementary, then one angle is the supplement of the other.

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

Answer:

Tia should sell 4(9), or 36, apples

Step-by-step explanation:

Find the value of the multiplier, p, that makes 4a + 2a = 54:  a turns out to be 9.  Then 4(9) + 2(9) = 54 is correct.  Tia should sell 4(9), or 36, apples and half as many oranges, or 18.  Note that 36 + 18 + 54.

Answer: Company B charges $0.08x + $30.00 more than Company A for x miles.

Step-by-step explanation:

The total cost for Company A for x miles is 0.09x + 30.50, and the total cost for Company B is 0.17x + 60.50. To find how much more Company B charges than Company A for x miles, we can subtract the cost of Company A from the cost of Company B:

(0.17x + 60.50) - (0.09x + 30.50)

Simplifying the expression, we get:

0.08x + 30.00

Therefore, Company B charges $0.08x + $30.00 more than Company A for x miles.

Answer:

If the earth didn't have a tilt, then we would only have one season which would most likely correspond to spring or autum.

Step-by-step explanation:

We would also expirience a mini summer when the earth is closest to the sun and we would expeirience a mini winter when the earth is farthest from the sun. Every where on the Earth would have a 12 hour sunlight days. It would still be warm at the equator and cold at the poles.

Step-by-step explanation:

The angle measures of J and L are given as follows:

m < J = m < L = 65º.

To obtain the angle measures, we must considering that the sum of the measures of the internal angles of a triangle is of 180º.

The internal angles for this problem are given as follows:

Angles J and L are congruent, meaning that they have the same measure, which is obtained as follows:

50 + x + x = 180

2x = 130

x = 65º.

Answer:

1/2 or 0.5.

Step-by-step explanation:

To calculate the probability of two cards chosen not including T, we need to determine the number of favorable outcomes (cards not including T) and the total number of possible outcomes.

From the provided sample space table:

The favorable outcomes for two cards not including T are:

P, M

P, P

P, R

P, M

R, M

R, P

R, R

R, T

There are 8 favorable outcomes.

The total number of possible outcomes is the number of cells in the table, which is 16.

Therefore, the probability of two cards chosen not including T is 8/16, which simplifies to 1/2 or 0.5.

Answer: 9/16

Step-by-step explanation:

hopefully (i think)

16 total options

9 don't include a T

so 9/16 don't include T

9/16 also don't include M, so they have equal probabilities, which makes sense since there are an equal number of each letter card

Answer: 4/5 = 180/b; b = 225 boys

Answer:

Given that there are 4 boys for every 5 girls, we can set up the following proportion:

4/5 = x/180

where x is the number of boys.

To solve for x, we can cross-multiply:

5x = 4 * 180

5x = 720

x = 144

Therefore, there are 144 boys.

Step-by-step explanation:

Answer:

3075

Step-by-step explanation:

So we have the sequence:

\(-12, -9, -6...\)

As given, this is an arithmetic sequence and we want to find the sum of the first 50 terms.

The formula for the sum of an arithmetic sequence is:

\(S=\frac{k}{2}(a+x_k}\)

Where k is the number of terms, a is the initial term, and x_k is the last term.

We already know that k is 50 because we want to find the sum of the first 50 terms. a is -12 because it's the first number in our sequence. To find our last term, we need to do some more work.

To find the 50th term, let's write an explicit formula for our sequence. The standard form for the explicit formula for an arithmetic sequence is:

\(x_n=a+d(n-1)\)

Where a is the first term, d is the common difference, and n is the nth term.

We already know that a, the first term, is -12. From the sequence, we can see that the common difference d is +3 because each term is 3 more than the previous one. -12 plus 3 is -9, plus 3 is -6, and so on.

So, substitute -12 for a and 3 for d gives us:

\(x_n=-12+3(n-1)\)

So, to find the 50th term for our sum, substitute 50 for n:

\(x_{50}=-12+3(50-1)\)

Subtract:

\(x_{50}=-12+3(49)\)

Multiply:

\(x_{50}=-12+147\)

Add:

\(x_{50}=135\)

So, the last term of our 50 number sequence is 135.

Now, let's go back to our original formula:

\(S=\frac{k}{2}(a+x_k})\)

Now we know all the values. So, substitute 50 for k (the amount of terms), -12 for a (the first term), and 135 for k (the 50th and last term). So:

\(S=\frac{50}{2}(-12+135)\)

Divide:

\(S=25(-12+135)\)

Add:

\(S=25(123)\)

Multiply:

\(S=3075\)

So, our sum is 3075.

And we're done!

Answer:

S₅₀ = 3075

Step-by-step explanation:

Find the sum, S50, of the first 50 terms of the following arithmetic series:(−12)+(−9)+(−6)

an = a₁ + (n - 1) d

where:

a₁ = 1st term                      = -12

n = nth term                      = 50

d = common difference  

  = a₂-a₁ = -9 - (-12)            =3

plugin values into the formula:

an = -12 + (50 - 1) 3

    = 135

sum of an arithmetic sequence:

Sn = n (a1 + an)  

              2

S₅₀  = 50 ( -12 + 135 )

                    2

S₅₀ = 3075
