Which set includes rational numbers but not natural numbers?
​

Answer:

4.0/5

Step-by-step explanation:

- She divided by 3 instead of the GCF.

- She didn’t complete step 4 and use the distributive property to be sure the expressions are equivalent.

- She didn’t undistributed the GCF from the original expression.

Answer:

Step-by-step explanation:

[tex]\frac{x}{4}[/tex] - 3 = [tex]\frac{1}{3}[/tex] + 2x ...... (1)

(1) × 12 :

3x - 36 = 4 + 24x

21x = - 40

x = - [tex]\frac{40}{21}[/tex] = [tex]-1\frac{19}{21}[/tex]

Answer:

[tex] y = \frac{3}{4}x - \frac{1}{4} [/tex]

Step-by-step explanation:

First, find the slope using the points (3, 2) and (-1, -1):

Slope = [tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-1 - 2}{-1 - 3} = \frac{-3}{-4} = \frac{3}{4} [/tex]

Find the y-intercept, b, by substituting x = -1, y = -1 and m = ¾ in y = mx + b.

-1 = ¾(-1) + b

-1 = -¾ + b

Add ¾ to both sides

-1 + ¾ = b

(-4 + 3)/4 = b

-¼ = b

Substitute m = ¾ and b = -¼ in y = mx + b.

The equation would be:

✅[tex] y = \frac{3}{4}x - \frac{1}{4} [/tex]

Answer: Your y-intercept form is -3 which is written b= -3

Your slope is 1/2 written like m= 1/2

Answer:

years = natural log (total / principal) / rate

years = natural log (18,400 / 9,200) / 10

years = natural log (2) / 10

years = 0.69314718056 / 10

years = 6.9314718056

and this would be the time for ANY amount of money to double.

Answer:

Option (C)

Step-by-step explanation:

Given:

In right triangles ΔAED and CEB,

m∠AED = m∠CEB = 90°

DE ≅ BE

AD ≅ BC

To prove:

ΔAED ≅ ΔCEB

                    Statements                         Reasons

1). m∠AED = m∠BC = 90°              1). Given

2). DE = BE                                     2). Given

3). AD = BC                                    3). Given

4). ΔAED ≅ ΔCEB                          4). By HL theorem of congruence

Option (C) is the answer.

Answer:

17) 6 inches.

18) 4.22 miles repeating

Step-by-step explanation:

17) Since we know that the steel structure is 19.8 feet tall in real life, we can use the scale to find the size on the map. First we can convert 3.3 feet to inches. 3 feet to inches is 36 inches and .3 feet is 3.6 inches. This means that we can write the scale as 1 inch : 39.6 inches. Now, we can convert the 19.8 feet to inches. The answer is 237.6 inches. Next, we can divide 237.6 in. by 39.6 in. which is 6 inches. Now, we can multiply 1 inch by 6 inches to get 6 inches.

18) We can use the same method to solve this question. Note: the numbers will get big. 11.4 miles to inches is 722304 inches. We can now divide this number by 2.7 inches. This will give us 267520 inches. This is also 4.22 miles repeating.

I am not 100% sure about question 18 but I am sure about 17!!!

Hope this Helps!!! :)

Answer:

26

Step-by-step explanation:

add both expressions to equal 90 (bc of the right angle)- x+11+2x+1=90

when you solve, you get x=26

Answer:

A) 26

Step-by-step explanation:

This is a right angle and the measure of a right angle is 90°

x+11+2x+1 = 90° add like terms

3x + 12 = 90° subtract 12 from both sides

3x = 78 divide by 3

x = 26

Answer:

30,240 ways

Step-by-step explanation:

This question is bothered on permutation. Permutation has to do with arrangement.

If there are 10 computers and 5 students, the number of ways students will sit at the computers if no computer has more than one student can be expressed as;

10P5 = 10!/(10-5)!

10P5 = 10!/(5)!

10P5 = 10*9*8*7*6*5!/5!

10P5 = 10*9*8*7*6

10P5 = 30,240

Hence the number of ways is 30,240 ways

Step-by-step explanation:

Is that the whole question?

Answer:

12.5

Step-by-step explanation:

The 20 lbs on the left side time the 5 feet is equal to 100.

You need the weight on the right side to equal 100 when it is multiplied to it's length from the fulcrum, which is 8.

All you need to do is divide 100 by 8, to get 12.5.

Answer:

25/100 or 1/4

Step-by-step explanation:

the 2 shaded rows on the top are both 10 and the bottom shaded row is 5 so the equation would be 2×10+5

Answer:

0.25

Step-by-step explanation:

The model represents one whole number (1)

Each square represents .01 of the whole number.

So if you add all the shaded squares together, you would get 25 shaded, which means the answer would be 0.25
