A)(-1, −52) and (-1, −32)
B) (1.8, -3.4) and (1.8, 2.2)
C) (-3.5, -4.2) and (-3.5, 1.3)
D) (4, 5) and (4, 1)
Answer: A
Step-by-step explanation:
A. yes because -52 and -32 are separated by a distance of 20 units
B. no because -3.4 and 2.2 are not separated by more than 5 units
C. no because -4.2 and 1.3 are not separated by more than 5 units
D. no becasue 5 and 1 are not separated by more than 5 units
Answer:
A, B, C
Step-by-step explanation:
A coordinate is written as (x, y) where:
x is the horizontal distance of the point from the origin.y is the vertical distance of the point from the origin.For a pair of coordinates to be separated by a vertical distance of greater than 5 units, the difference in their y-values should be greater than 5. To find the difference between two values, subtract the smaller value from the larger value.
A. (-1, -52) and (-1, -32)
Difference in y-values: (-32) - (-52) = 20
B. (1.8, -3.4) and (1.8, 2.2)
Difference in y-values: (2.2) - (-3.4) = 5.6
C. (-3.5, -4.2) and (-3.5, 1.3)
Difference in y-values: (1.3) - (-4.2) = 5.5
D. (4, 5) and (4, 1)
Difference in y-values: 5 - 1 = 4
Therefore, coordinate pairs A, B and C are all separated by a vertical distance of greater than 5 units.

7.6.3. A kangaroo chases a rabbit that starts 150 feet ahead of the kangaroo. For every 12 -foot leap of the kangaroo, the rabbit makes a 7 -foot leap. How many leaps will the kangaroo have to make to catch up to the rabbit if the two animals always leap at the same time?
Answer:
The number of leaps will the kangaroo have to make to catch up to the rabbit if the two animals always leap at the same time is 30 times.
Step-by-step explanation:
Given:
A kangaroo chases a rabbit that starts 150 feet ahead of the kangaroo.
For every 12 -foot leap of the kangaroo, the rabbit makes a 7 -foot leap.
Find:
the number of leaps will the kangaroo have to make to catch up to the rabbit if the two animals always leap at the same time
Step 1 of 1
The kangaroo gains 5 feet on every leap.
The kangaroo must gain 150 feet total,
so it must jump [tex]\frac{150}{5}=30$[/tex] times to catch the rabbit.
Kangaroo needs 30 leaps to make to catch up to the rabbit if the two animals always leap at the same time.
What is an equation?Two algebraic expressions having same value and symbol '=' in between are called as an equation.
Given:
A kangaroo chases a rabbit that starts 150 feet ahead of the kangaroo.
For every 12 -foot leap of the kangaroo,
the rabbit makes a 7 -foot leap.
Let n be the number of leaps.
According to the question:
We have the equation.
To solve for x;
12x = 7x + 150
12x - 7x = 150
5x = 150
x = 150/5
x = 30
Therefore, the Kangaroo needs 30 leaps to catch the rabbit.

On a snowy day 85% of the students of Wilson high school were present. If 572 of the students were present, how many students were enrolled at the school?
Answer:
673
Step-by-step explanation:
okay so uh this is my way and the answer works so like yea teachers dont show like this but ii figured this works
okay so
85/100 = 572/?
so if you divide 85 by 85 its gonna equal 1 and 1 times 100 is gonna be 100
useing the same concept, it should be the same with 572 , but instead of divideing by 572, divide by 85.
basically 572/85
okay now thats gonna give you 6.72941176471 thats vasically 1% of the population.
so multiply 6.72941176471 * 100
so now you have
672.941176471 and you can round this to 673 kids.
and you know its right since 85% of 673 is 572.05 and you can sound to 572
Answer:
673 students
Step-by-step explanation:
Divide the number of students who applied and the decimal of the percentage they represent.
85% = 85/100 = 0.85
572/.85 = 673

8.45 At some point in the season, the Unicorns had won 60% of their basketball games. After that point, they won 8 more games and lost 2 , to finish the season having won 65% of their games. How many games did the Unicorns play during the season?
Hint: Assign a variable.
Answer:
The total number of games won by Unicorn is 40.
Step-by-step explanation:
We are given with a word problemWe are asked to find the number of unicorns played during the seasonWe can do this in two stepsStep 1: Finding the win percentage
Step 2: Finding the number of unicorns played during the season
Step 1 of 2
Let the number of games played by unicorn be x.The unicorn won 60% of the first x-10 games That is [tex]$\frac{60}{100} \times(x-10)$[/tex]
Combining the 8 games we get,
[tex]$$\begin{gathered}\frac{60}{100}(x-10)+8=\frac{60}{100} \times x-\frac{60}{100} \times 10+8 \\0.6 x-6+8=0.6 x+2\end{gathered}$$[/tex]
Step 2 of 2
The unicorn totally won 65% of the games played.
That is [tex]$\frac{65}{100} \times x=0.65 x$[/tex]
Equating both the equation gives
[tex]$$\begin{gathered}0.6 x+2=0.65 x \\2=0.65 x-0.6 x \\2=0.05 x \\\frac{2}{0.05}=x \\40=x\end{gathered}$$[/tex]

8.3.4 Karl bought five folders from Pay-A-Lot at a cost of $2.50 each. Pay-A-Lot had a 20% -off sale the following day. How much could Karl have saved on the purchase by waiting a day?
Answer:
Karl could have saved $2.50
Step-by-step explanation:
Cost of folders without the sale: 2.5*5 = $12.50
Cost of folders with the sale: 0.8*2.5 = $2 per folder * 5 folders = $10.00
Difference between prices: 12.5-10 = $2.50
Answer:
2.50$ Karl could have saved on the purchase by waiting a day.
Step-by-step explanation:
Given: total number of folders Karl bought is 5 .
The cost of each folder is 2.50$.
20% off sale the following day at Pay-A-Lot.
we have to find the 20% of each folder and then add them to get the final saving of Karl if he had waited for a day.
Step 1 of 2
20% of 2.50$ is equal to
[tex]$$\begin{aligned}&=2.50 \cdot 20 \% \\&=2.50 \cdot \frac{20}{100} \\&=0.50 \$\end{aligned}$$[/tex]
this is the amount Karl would save on each folder if waited for a day or this is the discount on the amount of 2.50$ that the shopkeeper will give the next day on each
Step 2 of 2
Karl bought 5 folders
so, total savings would be equal to
[tex]$$\begin{aligned}&=5 \cdot 0.50 \\&=2.50 \$\end{aligned}$$[/tex]
