Answer:

13th Amendment- C

14th Amendment- A

15th Amendment- B

Step-by-step explanation:

Answer:

13th C

14th A

15th B

Step-by-step explanation:

You have to think of it in events in order. Slaves can't vote until they're free, so the thirteenth amendment gets rid of slavery. It wouldn't make sense if slaves could vote without other freedoms, so freedoms come first. 14th is B for this reason. Lastly, the fifteenth amendment grants African American men to vote years down the road (women weren't allowed to vote yet at all, so the African American females also didn't have this right)

Answer:

The first question

cos 30 = 50/x

√3/2 = 50/x

x√3 = 100

x = 100√3/3

x = 57.7350 ≈ 57.74

The second question

sin 45 = x/55

√2/2 = x/55

55√2 = 2x

x = 55√2/2

x = 38.8908 ≈ 38.90

The third question

cos 40 = x/34

x = 34 × 0.7660

x = 26.044

Answer: y = 6

Step-by-step explanation:

This is still in slope intercept form but the only difference is that x equals 0.

If this confuses you, you can write

y = 0x+6 which would still be correct however, your teacher might prefer

y = 6 more.

Answer:

38 ft^2

Step-by-step explanation:

you can change the model into two different shapes. one can be

4 by 2

the other will be

3 by 10

you find the produnt of these equations. in this case, its 8 and 30.

8 + 30 = 38.

Answer:

38 sq. ft.

Step-by-step explanation:

10 x 3 = 30 sq. ft.

4 x 2 = 8 sqft.

30 + 8 = 38 sq ft.

I think the correlation is negative because the graph is going down.

Using the midpoint concept, it is found that:

The midpoint of a line segment is given by the mean of the coordinates of it's endpoints.

For the first segment, which endpoints [tex](2, \sqrt{3})[/tex] and [tex](-6, 5\sqrt{3})[/tex]:

[tex]x_M = \frac{2 - 6}{2} = -2[/tex]

[tex]y_M = \frac{\sqrt{3} + 5\sqrt{3}}{2} = 3\sqrt{2}[/tex]

The midpoint is [tex](-2, 3\sqrt{2})[/tex]

For the second segment, which endpoints [tex]\left(-\frac{5}{3}, \frac{2}{5}\right)[/tex] and [tex]\left(\frac{1}{3}, \frac{3}{2}\right)[/tex]:

[tex]x_M = \frac{-\frac{5}{3} + \frac{1}{3}}{2} = -\frac{4}{6} = -\frac{2}{3}[/tex]

[tex]y_M = \frac{\frac{2}{5} + \frac{3}{2}}{2} = \frac{\frac{4 + 15}{10}}{2} = \frac{19}{20}[/tex]

The midpoint is [tex]\left(-\frac{2}{3}, \frac{19}{20}\right)[/tex]

Answer:

She can only display each item 56 times

Step-by-step explanation:

Since she has 72 stamps and 56 coins to have a even amount of both she can only make 56 displays

Answer: 8

Step-by-step explanation: Solve this problem with GCF (Greatest Common Factor).

Factors of 56: 1, 2, 4, 7, 8, 14, 28 and 56.

Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36 and 72.

So, the biggest among the numbers that are matching is 8.

Answer:

65 and 325

Step-by-step explanation:

(l+w)*2 = 780

l+w = 390

l = 5w

5w + w = 390

6w = 390

w = 65

length = 325

h (-2) = (-2)^2 + 1 = 5

f (-2) = 2(-2) - 1 = -5

5 - (-5) = 10.

Answer:

75/3=25

25*4= 100 words

Answer:

x = ± 5

Step-by-step explanation:

x² - 25 = 0 ( add 25 to both sides )

x² = 25 ( take square root of both sides )

x = ± [tex]\sqrt{25}[/tex] = ± 5

That is x = - 5, x = 5

which would =to I/rt=P

The answer is D. (-160)÷8

The answer can t be a decimal therefore a and c are out. The answer has to be negative bc it was a lost. Therefore since -160 was a loss it has to be negative

Answer:

D

Step-by-step explanation:

Loss = -160

It went up 7 feet

Step-by-step explanation:

3 + 7 = 10

Sea level is measured in this case in absolute value, so there are no negatives.

The point of intersection is the point where two or more functions meet.

The graphs of the hyperbola and ellipse have 0 point of intersection

The given parameters are:

[tex]\mathbf{3x^2 - 4y^2 + 4x - 8y + 4 = 0}[/tex]

[tex]\mathbf{3x^2 + y^2 + 4x - 3y + 4 = 0}[/tex]

To determine the points of intersection, we simply equate both equations.

So, we have:

[tex]\mathbf{3x^2 + y^2 + 4x - 3y + 4 = 3x^2 - 4y^2 + 4x - 8y + 4 }[/tex]

Cancel out the common terms

[tex]\mathbf{y^2 - 3y = - 4y^2 - 8y }[/tex]

Collect like terms

[tex]\mathbf{y^2 +4y^2= 3y - 8y }[/tex]

[tex]\mathbf{5y^2= - 5y }[/tex]

Divide through by 5

[tex]\mathbf{y^2= - y}[/tex]

Divide through by y

[tex]\mathbf{y= -1}[/tex]

The system of equation does not give room to calculate the x-coordinate at the x-axis.

Hence, the graphs of the hyperbola and ellipse have 0 point of intersection
