Using number line, the difference in the amount of Pizza they ate is 0.75
What is the difference between the amounts of pizza eaten by the two competitors in a minute?To compare the amounts of pizza eaten by Sandy and James in 1 minute, we need to first calculate how many slices they eat in 1 minute.
Sandy can eat 6.5 slices in 2 minutes, which means she can eat 6.5/2 = 3.25 slices in 1 minute.
James can eat 3 slices in 1.5 minutes, which means he can eat 3/(1.5/2) = 4 slices in 1 minute.
Therefore, James can eat more pizza in 1 minute than Sandy.
To show the difference on a number line, we can mark 3.25 and 4 on the line, and subtract 3.25 from 4 to get the difference:
0 1 2 3 4
|---------|---------|---------|---------|
Sandy: 3.25
James: 4
Difference: 0.75
So the difference between the amounts of pizza eaten by James and Sandy in 1 minute is 0.75 slices.

Hey could you help me with this: A machine pours 250 millilitres of juice every 4 seconds. How many litres of juice does the machine pour every minute?`
Answer:
15000
Step-by-step explanation
4x15=60
60x250=15000
The rate of the juice poured by the machine every minute is 10 liters.
What is the ratio of two numbers?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.
Hope this helps!!

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:

In the figure below, m angle a=3x+5;m angle b=5x-18 , and m angle c=7x-2 .
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 !!

i need help, i don't get this problem
need some help please
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.
Triangle ABC is a scaled copy of triangle DEF. Side AB measures 12 cm and is the longest side of ABC. Side DE measures 8 cm and is the longest side of DEF.
a)Triangle ABC is a scaled copy of triangle DEF with what scale factor?
b)Triangle DEF is a scaled copy of triangle ABC with what scale factor?
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
