Answer:

a) 3/2 or 1.5

b) 2/3 or ≈.66

Step-by-step explanation:

AB corresponds to DE because they are both the longest sides of their respective triangles.

a) The scale factor would be what you would multiply 8 by to get 12. 12/8 is 3/2 or 1.5

b) The scale factor would be what you multiply 12 by to get 8. 8/12 is 2/3 or ≈.66

Answer:

$0.99

Unit rate is cost for 1 individual (song)

Step-by-step explanation:

$3.96/4

0.99

99 cents

28 to 42 means 28/42

We now reduce 28/42 to lowest terms.

28 ÷ 7 = 4

42 ÷ 7 = 6

We now have 4/6.

We now reduce 4/6.

4 ÷ 2 = 2

6 ÷ 2 = 3

Final answer: 2/3

Answer:

basically you're solving for x.

Step-by-step explanation:

x = 11/4 for exact form

in decimal form

x= 2.75

in mixed number form

x = 2 3/4

but in this case it's 2.75

Answer:

15000

Step-by-step explanation

4x15=60

60x250=15000

The rate of the juice poured by the machine every minute is 10 liters.

The ratio of two numbers a and b can be written as a : b = a/b.

The ratio of two quantities is the unit rate of one quantity with respect to the other.

The total amount of juice poured by machine is 250 ml.

And, the time taken for that is 4 second.

In order to find the rate in liter per minute, convert the time in seconds to minutes and volume in liters as follows,

60 second = 1 minute

⇒ 1 second = 1/60 minute

⇒ 4 second = 4/160 = 1/40 minutes.

And, 1 liter = 1000 milliliter

⇒ 1 milliliter = 1/1000 liter

⇒ 250 milliliter = 250/ 1000 = 1/4 liter

Now, the rate of juice poured per minute is given as,

1/4 ÷ 1/40

⇒ 1/4 × 40

⇒ 10 liter per minute

Hence, the machine pour every minute 10 liter of juice.

Answer:

The 2-yard pièce of cotton cloth for $13.26

Step-by-step explanation:

2 yards is 6 feet then it would be $2.21 per foot.

The 17 foot piece would cost $3.29 per foot.

To answer this question, you need to determine which one has a lower price per unit.  In this scenario, you must divide the price of the cloths by their length in feet.

For the 2-yard piece of cotton cloth, first convert the length to feet.  There are three feet in a yard, so the cloth is 6 feet.  Then divide:

13.26/6=2.21

For the 17-foot piece of cotton cloth, simply divide:

55.93/17=3.29

The 2-yard piece of cotton cloth for $13.26 is the better buy because it has a lower unit price.

Answer: 0.8

Step-by-step explanation:

Add a decimal point, and then add a zero to 8. Divide 8.0 ÷ 10. Your answer is 0.8 because 0.8 goes into 8 10 times. There is no remainder.

Answer:

[tex]\mid x+3\mid\ge 2[/tex]

Step-by-step explanation:

Inequalities

The  solution for the inequality:

[tex]\mid x+a\mid\ge b[/tex]

Can be expressed as:

[tex]x+a\ge b[/tex]

OR:

[tex]x+a\le -b[/tex]

Subtracting a to both inequalities:

[tex]x\ge b-a[/tex]

[tex]x\le -b-a[/tex]

Comparing to the given solutions, we have:

[tex]b-a=-1[/tex]

[tex]-b-a=-5[/tex]

Adding both equations:

[tex]-2a=-6[/tex]

Solving:

a=3

b=2

Thus, the required inequality form is:

[tex]\mathbf{\mid x+3\mid\ge 2}[/tex]

Answer:

Dan

Step-by-step explanation:

To figure out who ate the most, you can convert each fraction to decimal form. Whichever value is the largest belongs to the person who ate the most of a Snickers.

6/7 = 0.86

3/4 = 0.75

0.86 is bigger than 0.75, which means that Dan ate more of a Snickers.

Answer:

∠a=44,∠b=47, ∠c=89

Step-by-step explanation:

we can note that

∠a+∠b+∠c=180

hence,

3x+5+5x-18+7x-2=180

therefore,

3x+5x+7x+5-18-2=180

15x-15=180

15x=180+15

15x=195

x=[tex]\frac{195}{15}[/tex]

then, x=13.

with this values we can find all the angles:

∠a=3x+5 ⇒∠a=3(13)+5⇒∠a=39+5⇒∠a=44

∠b=5x-18⇒∠b=5(13)-18⇒∠b=65-18⇒∠b=47

∠c=7x-2⇒∠c=7(13)-2⇒91-2⇒∠c=89

We can corroborate these result by adding them.

∠a+∠b+∠c=

44+47+89=180

Thats right !!
