Jenna took a math test and answered 15 out of 20 answers correctly. What percent of the questions did she answer correctly?

Answers

Answer 1

Answer:

75%

Step-by-step explanation:

Answer 2

Answer:

75%

Step-by-step explanation:

15   x  5           75

----      =          -------

20  x  5           100

Cent means 100, so percent literally means per 100 like in century or centennial. So, I put it into a fraction over 100. Now it is 75 per 100. If you remember, per 100 is percent, it means the answer id 75 percent. You can also write it as 75%.

Determine the equation of the graph with the coordinates of (4, -1)

O y = (x-4)2 - 1
O y=(x + 4)2 + 1
O y = (x + 4)2 - 1
O y = (x - 4)2 + 1

Answers

Answer:

The required equation of the graph with the coordinates of (4, -1) will be:

[tex]y=\left(x-4\right)^2-1[/tex]

The graph is also attached.

Step-by-step explanation:

Given the coordinates (4, -1)

If we put the coordinate values (4, -1) in the given equations, we determine that only [tex]y=\left(x-4\right)^2-1[/tex] is the valid equation as it satisfies the given coordinate value.

For example, putting  (4, -1) in the equation

[tex]y=\left(x-4\right)^2-1[/tex]

[tex]\left(-1\right)=\left(4-4\right)^2-1[/tex]

[tex]-1=\left(0\right)^2-1[/tex]

[tex]-1=0-1[/tex]

[tex]-1=-1[/tex]

So, the equation [tex]y=\left(x-4\right)^2-1[/tex] is true for the coordinate values (4, -1).

Therefore, the required equation of the graph with the coordinates of (4, -1) will be:

[tex]y=\left(x-4\right)^2-1[/tex]

Please check, the graph is also attached.

Thomas earns extra money babysitting. He charges 45.50 for 5 hours and 72.80 for 8 hours. How much will thomas charge for 3 hours.

Answers

3 hours would be $27.30
You take $45.50 and divide it by 5 to get the charge of one hour then times it by three.
You can also do $72.80 divided by 8 to get the charge of one hour, then times it by 3.

What is the diameter of a circle with the equation (x – 4)2 + (y + 6)2 = 64?
a. 4
b. 8
c. 16
d. 64

Answers

Answer:

16

Step-by-step explanation:

step one:

given data

we are given the equation of the circle as

[tex](x -4)2^ + (y + 6)^2 = 64[/tex]----------------1

We know that the general equation for a circle is

[tex]( x - h )^2 + ( y - k )^2 = r^2[/tex]--------------2

comparing the two equations above, we can immediately compare the term on the other side of the equality sign that is

r^2=64

square root both sides

r=√64

r=8

since the radius is 8, hence the diameter is

d=2

r= 2*8

3. (Angles add up to 180)

30x + 4 + 86 = 180

30x + 90 = 180

subtract 90 from both sides

30x = 90

Now divide by 30

x = 3

Check your work ( input 3 to the equation)

30(3) + 4 + 84

90+ 90 = 180  it works :)  

4. (Angles are adjacent to each other so there equal)

10x - 3 = 77

add 3 to both sides

10x = 80

divide it by 10

x = 8

Check your work ( input 8 to the equation )

10(8) -3 = 77

80 - 3 = 77

77 = 77

Using the Incenter P, find the measure of ∠ZPX.




117°

140°

64°

129°

42°

132°

Answers

Answer:

The measure of ∠ZPX is 63°

Step-by-step explanation:

The given parameters are;

The incenter of the triangle = P

m∠KXP = 31°, m∠PYJ = 27°, [tex]\overline {ZP}[/tex] = 20 feet

Given that the segment [tex]\overline {XJ}[/tex] from the vertex, X, passes through the incenter of the triangle, we have;

The segment [tex]\overline {XJ}[/tex] bisects ∠KXL to form ∠KXP and ∠LXP

Therefore, ∠KXP = ∠LXP = 31°

∠KXL = ∠KXP + ∠LXP = 31° + 31° = 62°

∠KXL = 62°

Similarly;

The segment [tex]\overline {YL}[/tex] bisects ∠KYJ to form ∠PYJ and ∠PYK

Therefore, ∠PYJ = ∠PYK = 27°

∠KYJ = ∠PYJ  + ∠PYK = 27° + 27° = 54°

∠KYJ = 54°

In ΔXYZ, we have, ∠LZJ + ∠KYJ + ∠KXL = 180° based on the sum of the interior angles of a triangle postulate

∴ ∠LZJ = 180° - (∠KYJ + ∠KXL) = 180° - (54° + 62°) = 64°

∠LZJ = 64°

The segment [tex]\overline {ZK}[/tex] bisects ∠LZJ to form ∠PZL and ∠PZJ

Therefore, ∠PZL = ∠PZJ

∠LZJ = ∠PZL + ∠PZJ = 2 × ∠PZL = 64°

∠PZL = 64°/2 = 32° = ∠PZJ

In ΔZPX, we have;

∠PZL + ∠LXP + ∠ZPX = 180° based on the sum of the interior angles of a triangle postulate

∠ZPX = 180° - (∠PZL + ∠LXP) = 180° - (32° + 31°) = 63°

∠ZPX = 63°

The measure of ∠ZPX = 63°

Answers

Answer:

A, B and D

Step-by-step explanation:

The zeros of f(x) are the points located on the x- axis, that is where y = 0

We can check which ones are the solutions by finding the zeros of f(x)

To find the zeros let f(x) = 0 , that is

(x² + 2x - 8)(x - 6) = 0 ← factorise the quadratic

(x + 4)(x - 2)(x - 6) = 0

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x - 2 = 0 ⇒ x = 2

x - 6 = 0 ⇒ x = 6

There are 3 zeros at x = - 4, x = 2, x = 6

These are located at A, B and D
