NEED HELP ASAP

Answers

Part A: Create an equation that shows the amount of money earned, E, for working x hours in a week when there is no overtime. (3 points)

x hours in a week and there is no overtime and x <= 35 so equation:

E(x) = 16x

Part B: Create an equation that shows the amount of wages earned, T, for working y hours of overtime. Hint: Remember to include in the equation the amount earned from working 35 hours. (3 points)

Regular hours = E(x) = $16 x 35 = $560

T(y) = 21y + 560

Part C: Marco earned $602 in 1 week. How many hours (regular plus overtime) did he work? Show your work. (4 points)

21y + 560 = 602

21y = 42

y = 2

Marco worked 37 hours (35 regular plus 2 hours overtime)

Consider the product P(x) = (3x2 - 6x + 2)(7x + 3).
What is the numerical coefficient of the x term in P(x)?
Enter only a number for your answer.

Answers

Answer:

-4

Step-by-step explanation:

Notice that the only way to multiply 2 numbers from each of the polynomials and get an x term is to multiply a constant and an x term.

The only ways to do that is to multiply -6x by 3 and 7x by 2.

After you're done multiplying, just combine the 2 like terms:

-18x+14x

=-4x

Therefore, the coefficient of the x term is -4.

In 2005, the UT Longhorns scored 15 times to win the Big 12 Championship Game 70-3. All of their points came from touchdowns (6 points each) and extra point kicks (1 point each). How many touchdowns and extra points did the Longhorns have in that game? (For the purposes of this problem, touchdowns and extra point kicks count as separate "scores".

Answers

Answer:

The number of touch downs = 11

The number of extra points = 4

Step-by-step explanation:

The number of times UT Longhorns scored = 15 times

The composition of the scores = Touch down and point kicks

The points with which UT Longhorns won the game = 70-3

The points that came from each touch down = 6 points

The points that came from each point kick = 1 points

We have;

The number of touch downs + Point kicks = 15

The number of touch downs = 15 - Point kicks

Let the number of point kicks = P

Therefore;

The number of touch downs = 15 - Point kicks = 15 - P

The number of touch downs = 15 - P

Given that the total points of UT Longhorns = 70, we have;

6 × (15 - P) + 1 × P = 70

90 - 6·P + P = 70

5·P = 90 - 70 = 20

P = 4

∴ The number of point kicks = P = 4

The number of point kicks, extra points = 4

The number of touch downs = 15 - P = 15 - 4 = 11

The number of touch downs = 11

Step-by-step explanation:

The value of the fraction is given by the equation A = 7 / 55

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first fraction be represented as p = 14/75

Let the second fraction be represented as q = 15/22

Now , A = p x q

Substituting the values in the equation , we get

A = ( 14/75 ) x ( 15/22 )

A = 210 / 1650

A = 42 / 330

A = 14 / 110

A = 7/55

Therefore , the value of A is 7/55

Hence , the fraction is A = 7/55

Given mn, find the value of x.

Answers

Answer:

x = 32 degrees

Step-by-step explanation:

since there is a line intersecting both of the lines you would do the opposite number to solve the problem. basically what i am trying to say is.

A straight line equals 180 degrees

and the given angle is 148 degrees

so just subtract.

180 degrees - 148 degrees = 32 degrees

so x = 32 degrees

to see if it is reasonable, look at the angle

if you look you can see that it is an acute angle

so, since 32 degrees is an acute angle, the answer is also reasonable.

so like i said,

x = 32 degrees

The interior angles of parallel lines and a transversal are the angles between the parallel lines.

The value of x is 32 degrees

Alternate interior angles of a parallel line add up to 180 degrees.

So:

[tex]\mathbf{148 + x = 180}[/tex]

Subtract 148 from both sides

[tex]\mathbf{148 - 148+ x = 180 - 148}[/tex]

Evaluate like terms

[tex]\mathbf{x = 32}[/tex]

Hence, the value of x is 32 degrees

d. m24 =
e. m25 =
f. m26 =

Answers

Answer/explanation:

Given:

m<8 = 23°

a. m<1 = 180° - m<8 (corresponding angles theorem and supplementary angles theorem)

m<1 = 180 - 23 = 157°

b. m<2 + m<1 = 180° (linear pair)

m<2 + 157° = 180°

m<2 = 180° - 153° = 23°

c. m<3 = m<1 (vertical angles are congruent)

m<3 = 157°

d. m<4 = m<2 (vertical angles are congruent)

m<4 = 23°

e. m<5 = m<1 (corresponding angles)

m<5 = 157°

f. m<6 = m<8 (vertical angles are congruent)

m<6 = 23°

g. m<7 = m<5 (vertical angles are congruent)

m<7 = 157°
