Answer:

She will earn $148.50 in overtime this week.

Step-by-step explanation:

First, you multiply 11 by 1.5. That gets you 16.5. So, for every overtime hour she works, she gets $16.50. Since she works 9 overtime hours, you multiply 16.5 by 9 to 148.5. So, she earns $148.50 for overtime this week.

Step-by-step explanation:

I think writing the given out helps a bit.

x = small angle

2x+3 = large angle <-- it's 2x since it's twice the small angle and +3 because it's 3 degrees more than the small angle.

small angle + large angle = 180

Now just substitute!

[tex]x+(2x+3)=180\\3x=177\\x=\frac{177}{3} \\x=59[/tex]

Now that you know what x equals (aka the smaller angle) now you can find the larger angle.

[tex]2(59)+3\\118+3\\121[/tex]

Answer:

The smaller angle equals 59°

The larger angle equals 121°

Good luck!

Answer:

D

Step-by-step explanation:

[tex]KQ = PN[/tex]

We can't state that because we don't know if ∠NPK is 90º

Triangle KPN is similar to triangle KQN

It is the same case as the alternative a, we can't say the triangles are similar because we don't the angles for KPN. We know that LN is perpendicular to NP, but we don't if NP is perpendicular to PK, ∠NPK might be 89,9º, that is almost 90º.

KP = 0.5 LN

Once the four sides of the square are equal, LQ = QN. But from the picture we can only state that KP length is approximately the length of NQ (or 0.5 LN)

PN || KM

That's the correct answer! Once ∠QNP is 90º, PN is perpendicular to KM.

Answer:

The measure of angle b is 15 degrees,

Step-by-step explanation:

Both triangles are isosceles. The inside one is also a right triangle. Since the big triangle is isosceles and the two angles add up to 120 degrees, they also have to be equal, meaning ∠P≅∠R=60 degrees. The inside triangle is also isosceles, meaning that m∠a=60°-b, which 60°-b representing the measure of the last angle in the smaller triangle. Since ∠a and the third angle are congruent, they each have to equal 45°. 60°-45°=15°. The measure of ∠b=15°.

Answer:

[tex]a_{n}[/tex] = 20n + 12

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 52 - 32 = 72 - 52 = 92 - 72 = 20

This indicates the sequence is arithmetic with explicit formula

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 32 and d = 20, thus

[tex]a_{n}[/tex] = 32 + 20(n - 1) = 32 + 20n - 20 = 20n + 12

The answers to the blanks are:

The “?” in the table represents the number 38 because the average rate of change on every interval of the function is 1/3.

Step-by-step explanation:

How you can see in the table, after the first values [x=-2, f(x)=5], each time that x add 1, f(x) add 3, (that is the reason why the average rate is 1/3), how you can see below:

2. x = 2 (were added 4 to the first number -2)

   f(x) = 17 (were added 12 to the first number 5)

3. x = 5 (were added 3 to the second number 2)

   f(x) = 26 (were added 9 to the second number 17)

4. x = 9 (were added 4 to the third number 5)

How in the last column were added 4, you must multiply this value by 3 (remember the average rate), so 4*3 = 12, now:

  f(x) = 38 (were added 12 to the third number 26)

Im pretty sure its 2 but not exactly

Answer:

Step-by-step explanation:

-x - 5y = -29 + 4y - y + 5

Add x to both sides

-x - 5y + x = -29 + 4y - y + 5 + x

-5y = 4y - y  -29 +5 + x  {Add the like terms}

-5y = 3y - 24 + x  {subtract 3y form both sides}

-5y - 8y = 3y - 24 + x - 3y

-13y = x - 24

Divide both sides by (-13)

y = (x-24)/-13

y = -(x-24)/13

Answer:

180-60 = 120 if triangle is not equilateral it cannot be isosceles then depending where the angles are they will show  60,60,60 if equilateral

For isosceles it would need to be 58 61 61 as 60, 60,60 cannot be isosceles.

Vectors 60 if right angled triangle = 90-60 = 30

So angles = 30 and 90 degree or just 120 if angle theta is a vector as explained below.

Step-by-step explanation:

Statement: If two vectors are represented by the sides of a triangle both in magnitude and direction taken in order, the resultant sum of the vectors is given by the closing third side of the triangle taken in the reverse order both in the magnitude and direction

Answer:

1) B

2) A

Step-by-step explanation:

1) When a triangle is similar it means that all the angle measures are the same.

So for triangle UVT the angle measures are:

U=29.95, V=56.25, T=93.82

For triangle RSQ the angle measures are:

R=29.95, S=56.25, Q=93.82

So the answer is that they are similar (triangle UTV ~triangle RQS)

2) For this problem each sided is proportional because of the parallel lines. (It's been a while since I've done this kind of math but I'll give it a go)

Answer: a. 43.443 km

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

27 miles to kilometers

Since 1 mile = 1.609344 km

We simply have to multiply the number of miles by 1.609344.

Mathematically speaking:

27 x 1.609344 = 43.4522 km

The closest result is option a. 43.443 km.

Combine like terms

5s +19 = 4

Subtract 19 from each side

5s +19-19 = 4-19

5s = -15

Divide by 5

5s/5 = -15/5

s = -3

Answer:

-3

Step-by-step explanation:

1) combine like terms:

5s--19=4

5s+19=4

subtract 19 from both sides:

5s=-15

s=-3

Answer:

  C(3, −3), D(−2, −3)

Step-by-step explanation:

The given segment is 5 units long. (You can subtract the coordinates or count the grid squares to see this.)

In order for the area to be 30 square units, the product of length and width must be 30.

  30 = 5×width

  30/5 = width = 6

The horizontal line that is 6 units below the one shown is at y = -3. That is, the coordinates of C and D will have y-values of -3. Only one answer choice matches.

Answer:

When using the given information, the diameter of the circle is going to be 28 mL.

Step-by-step explanation:

First, we need to know the formula for finding the area of a circle.

[tex]Area=r^2\pi[/tex]

Now, we need to rearrange the formula so we can find the radius.

[tex]Radius=\sqrt{\frac{A}{\pi} }[/tex]

Next, we plug in the given area into the equation.

[tex]Radius=\sqrt{\frac{615}{\pi}}[/tex]

[tex]Radius=\sqrt{196}[/tex]

[tex]Radius=14[/tex]

Now that we have the radius, we can find the diameter. The radius is half the length of the diameter. So, in order to find the diameter, we have to multiply the radius by 2.

[tex]14 * 2=28[/tex]

So, the diameter of the circle is 28 mL

Answer:

B, C and F

Step-by-step explanation:

Given

f(x) = [tex]\frac{7}{2x(x+3)(x-9)}[/tex]

The denominator of f(x) cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the values that x cannot be and if the numerator is non zero for these values then they are vertical asymptotes.

solve

2x(x + 3)(x - 9) = 0

Equate each factor to zero and solve for x

2x = 0 ⇒ x = 0 → C

x + 3 = 0 ⇒ x = - 3 → B

x - 9 = 0 ⇒ x = 9 → F
