Answers
Answer: please read the explanation :)
Step-by-step explanation:
Make the precent a whole number then subtract it form 100 then the answer turn it to a percent :)
1) 100 - 65 = 35 = 35% of boys in the class
2) 100 - 27 = 63 = 63% of skirts that are not red
3) 100 - 78 = 22 = 22% non swimmers
4) 100 - 43 = 57 = 57% what he got wrong
5) 100 - 45+42 = 13 = 13% the games they tied
6) 100 - 28+35 = 37 = 37% who chose football
7) 100 - 38 = 62 = 62% are dogs
8) 100 -35 = 65 = 65% scored over average
9) 100 -12 = 88 = 88% percent
10) 100 - 6 = 94 = 94% can ride the bike

A nature preserve worker calculates there are 6,000 deer in Sharon Woods Park. She also estimates that 75 more deer die than are born each year.
a. Write a linear function to estimate how many deer will be in the park in x years.
b. Use the linear function to predict how many deer will be in the park in 3 years.
c. In how many years will there be 5,325 deer left in Sharon Woods Park?
Answers
The linear equation used to represent this situation is y = -75x + 6000
A linear equation is in the form:
y = mx + b;
where y, x are variable, m is the slope of the line and b is the y intercept.
Let y represent the amount of deer present in x years. There are 6000 deer presently, hence a = 6000. Also 75 more deer die than are born each year. Hence m = -75.
The linear equation is given by:
y = -75x + 6000
In 3 years:
y = -75(3) + 6000
y = 5775
For there to be 5325 deer:
5325 = -75x + 6000
x = 9 years

If a car averages 22 miles per gallon, how many kilometers per liter is this?
Answers
We have to convert the units. 1 mile = 1.60934km, 1 gallon = 3.78541km
Since it's mile per gallon, we divide the units mentioned above.
1 mile / 1 gallon = 1 km / 1 gallon = 1.60934 / 3.78541 = 0.4251
Now multiply this result as a factor to 22
That is 22 * 0.4251 = 9.3522
So the answer is 9.3522

Answer: -1There were 560 people at a play. The admission price was $2 for
adults and $1 for children. The admission receipts were $860.
How many adults and how many children attended?
Answers
Answer:
• For this one we need to split this problem into two equations:
• a (adults) + c (children) = 560
• 2a + c = $860
• Then we substitute 560 - a for c in the second equation.
2a + 560 - a = 8602a + 560 = 8602a = 5302a = 265• Then we plug this into the first equation:
265 + c = 560c = 295Step-by-step explanation:

The mean speed of the sample pitches is 37 miles per hour. Floretta knows from experience that the standard deviation for her pitch speed is 5 miles per hour.

If Alex is 14 years old, and Ben is 17 years old, in how many years will the sum of their ages be 169 years?
Answers
Answer:
69 years
Step-by-step explanation:
Sum of Alex's and Ben's current age
= 14 +17
= 31 years
For every year, Alex and Ben will each be one year older. Thus, 2 years would be added to the sum of their ages with each passing year.
Difference in the sum of their ages
= 169 -31
= 138 years
Number of sets of 2 years
= 138 ÷2
= 69
Thus, the sum of their ages will be 169 in 69 years.

Answers
Positive, because the products (-5)(-3) and (-8)(-6) are positive, and the product of two positive numbers is positive
=======================================================
Explanation:
Recall we have these rules
positive times positive = positivepositive times negative = negativenegative times negative = positiveHere is one example for each rule
8*7 = 565*(-9) = -45-2*(-4) = 8So based on that, we know that (-5)(-3) is positive. The two negatives cancel each other out so to speak. The same goes for (-8)(-6). Then multiplying any two positive numbers produces another positive outcome.
