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 cow's tail will grow 25 inches more intotal

The cows tail will be 28 inches long.

Step-by-step explanation:

12 months equals to one year (leap year not included) cows tail

grows 5 inches every 6 months. So, 5 x 5 = 25 + the 3 inches from its previous tail will give us total for all. so the answer is 28 in all or 25 for how much it has grown.

That's a long tail ;-;

In total Victoria worked for [tex]8 \frac{1}{4}[/tex] hours. Therefore, option D is the correct answer.

Given that, Victoria logged in to work at 8:15 am and logged out at 4:25 pm.

A clock or a timepiece is a device used to measure and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month and the year.

Victoria logged in to work at 8:15 am

8:15 am →9:15 am →10:15 am→11:15 am→12:15 pm→1:15 pm→2:15 pm→3:15 pm→4:15 pm

8:15 am →9:15 am = 1 hour

9:15 am →10:15 am = 1 hour

10:15 am→11:15 am = 1 hour

11:15 am→12:15 pm = 1 hour

12:15 pm→1:15 pm = 1 hour

1:15 pm→2:15 pm = 1 hour

2:15 pm→3:15 pm = 1 hour

3:15 pm→4:15 pm = 1 hour

So, in total Victoria logged in for 8 hours 10 mins

Its nearest quarter is [tex]8 \frac{1}{4}[/tex] hours

In total Victoria worked for [tex]8 \frac{1}{4}[/tex] hours. Therefore, option D is the correct answer.

Answer:

 X= -2

Step-by-step explanation:

Answer:

Step-by-step explanation:

d = 102°

e = 56°

f = 22°

The measurement of each of the angle is -

∠e = 56°  

∠d = 102°

∠f = 22°

Given are the intersecting lines as shown in the image.

We can write that -

∠e = 56°                                 {vertically opposite angles}

∠d = 102°                                {vertically opposite angles}

∠f = {180 - (102 + 56)}             {vertically opposite angles}

∠f = 22°

Therefore, the measurement of each of the angle is -

∠e = 56°  

∠d = 102°

∠f = 22°

Answer:

I only know what y is, y is 4a, wait I think a is z and z is a. I’m not sure

Step-by-step explanation:

Step-by-step explanation:

value of a :

4a + a = 180°

5a = 180°

a = 36°

value of y :

y = 4a

y = 4(36)

y = 144°

value of z :

z = a

z = 36°

Answer:

The dimensions are 18m by 18m

Step-by-step explanation:

Since the problem says the floor is square, we know that all 4 sides are equal. The area for a square is one side squared. Since we do not have the actual length per side, we write the following formula: x^2= 324.

From there, we simply take the square root to figure out that one side is 18 meters. Once we know one side, we know all 4 because a square has equal sides. Therefore, the dimensions of the floor are 18m x 18m. I hope this helps!

Answer:

Step-by-step explanation:

Let d represent the number of dimes (the higher-value coin). Then the number of nickels is 40-d, and the total value in cents is ...

  5(40 -d) +10(d) = 290

  200 +5d = 290

  5d = 90

  d = 18

  40 -d = 22

There are 22 nickels (and 18 dimes).

Additional comment

If you write the equation in terms of the number of nickels (n), you end up with the equation -5n = -110. The formulation used above avoids negative numbers, which can be confusing for some people.

Answer:

[tex]\left\lbrace\begin{aligned}& a_{1} = 7 \\ & a_{n+1} = a_{n} - 3 && \text{for $n \ge 1$}\end{aligned}\right.[/tex].

Step-by-step explanation:

An arithmetic sequence could be defined using only two pieces of information:

The arithmetic sequence in this question is given in the explicit form, [tex]a_{n} = 7 - 3\, (n - 1)[/tex], which is equivalent to [tex]a_{n} = 7 + (-3)\, (n - 1)[/tex]. In the explicit form, [tex]a_{1}[/tex] and [tex]d[/tex] are described in the same equation:

[tex]\text{$a_{n} = a_{1} + d\, (n - 1)$ for $n \ge 1$}[/tex].

Compare [tex]a_{n} = a_{1} + d\, (n - 1)[/tex] with [tex]a_{n} = 7 + (-3)\, (n - 1)[/tex]: [tex]a_{1} = 7[/tex] whereas [tex]d = -3[/tex].

When an arithmetic sequence is given in the recursive form, [tex]a_{1}[/tex] and [tex]d[/tex] are specified in two separate equations:

[tex]\left\lbrace\begin{aligned}& a_{1} = a_{1} \\ & a_{n+1} = a_{n} + d && \text{for $n \ge 1$}\end{aligned}\right.[/tex].

In this question, it was found that [tex]a_{1} = 7[/tex] whereas [tex]d = -3[/tex]. Hence, the corresponding recursive formula for this arithmetic sequence would be:

[tex]\left\lbrace\begin{aligned}& a_{1} = 7 \\ & a_{n+1} = a_{n} + (-3) && \text{for $n \ge 1$}\end{aligned}\right.[/tex].

Answer:

0.84 x 6 = 5.04

Step-by-step explanation:

5.04 is the answer.

Answer:

Answer B is correct

Step-by-step explanation:

We want to multiply 6 and 0.84

First you have to forget about decimals and multiply those two numbers

084

   ×6

-----------------

 =  504

And then consider about the number of decimal places. According this sum you have 2 decimal places ( 0.84 )

And now you can write the answer as

= 5.04
