Answer:
13) 23/4 14) 13/2 15) 6 1/2 16) 2 7/12
Step-by-step explanation:
13) (4 x 5) + 3 = 23 -> 23/4
14) (2 x 6) + 1 = 13 -> 13/2
15) 13/2 = 6.5, then take the number on the left of the decimal so, 6, as your whole number. After that, multiply it by the denominator so 6 x 2 = 12, then subtract the 12 with the numerator given in the improper fraction so, 13-12 = 1. The answer you get (which is 1 in this case) will be your numerator in for the mixed fraction. -> 6 1/2
Note: the denominator always stays the same
16) 31/12 = 2.58... take the 2 as your whole number.
2(whole number) x 12(denominator) = 24
31 - 24 = 7
= 2 7/12

Matching the population trend to a contributing factor:
Contributing Factors Population Trends
government-sponsored family control programs Low birth rate
agricultural economies increase in food supply
medical advancements low death rate
Industrial Revolution high birth rate
Step-by-step explanation:
a) Contributing factors are some negative or positive factors that influence or cause a single event or chain of events that result to the incident.
b) Defining population trends:
1) High birth rate: the industrial revolution triggered high birth rate, following increased food supply and medical advancements.
2) Low death rate: medical advancements brought about low death rate as better healthcare is provided to the sick.
3) Increase in food supply: large-scale agricultural economies ensured increasing food production and supply.
4) Low birth rate: when governments started sponsoring family control programs, the resulting effect was low birth rate.

Rob loves to snowboard in the winter, so he is looking at the cost of ski lift tickets for different mountains. Peak Point is selling 5-day packs for $275.60. Grand Mountain is selling 3-day packs for $174.75. Which mountain offers the better deal?
Answers
Answer: Peak Point offers the better deal.
Step-by-step explanation:
To find which has the best price, we need to know the cost for one day at each mountain. To do this, we would divide the cost of each pack by the number of days it pays for, so
$275.60/5 days
and $174.75/3 days.
Peak Point costs $55.12 per day while Grand mountain costs $58.25 for each day. This shows that Peak Point clearly has the better deal, costing $3.13 less for every day included in the pack.

7th grade math need asap. Lilliana is training for a marathon. She runs the same distance every day for a week. On Monday, Wednesday, and Friday, she runs 2 laps on a running trail and then runs 6 more miles. On Tuesday and Sunday, she runs 4 laps on the trail and then runs 2 more miles. On Saturday, she just runs laps. How many laps does Lilliana run on Saturday?
Answers
Answer:
5 Laps
Step-by-step explanation:
The question says that she runs the same distance everyday. This shows us that...
2 laps on a running trail and 6 more miles = 4 laps on a running trail and 2 more miles
We can turn laps into the variable L and miles into the variable M to create an equation
2 L + 6 M = 4 L + 2 M
We can start by subtracting 2 M from both sides to get:
2 L + 4 M = 4 L
Now, we can subtract 2 L from both sides
4 M = 2 L
This tells us that 2 laps are 4 miles which means that 1 lap is 2 miles.
Now, we can break down either side of the equation. Let's break down
2 L + 6 M
First, we can turn the miles into laps. We know that 2 miles is one lap so we can divide 6 by 2. Our Equation:
2 L + 3 L
Now, we can simplify this :
5 L
Now we know that she ran 5 laps on saturday.
Hope this Helps!!! :)

A= 2h(B+b); A=44, B = 2, b= 9
h=
Answers
Step-by-step explanation:
44 = 2 * h * 11
44 = 22 * h
divide 22 on both sides, and you get the answer
2 = h
A = 2h(B + b)
Disregard my first reply.
Here is the math work.
44 = 2h(2 + 9)
44 = 4h + 18h
44 = h(4 + 18)
44/(4 + 18) = h
44/22 = h
Divide top and bottom by 11.
4/2 = h
2 = h
Done!

Wilfred is feeding his goats. He gives 56% of the bag of feed to the goats in field A and the rest to the goats in field B. If the bag has 21kg of feed, how much do the goats in field A get?
Answers
Answer:
[tex]Feeds = 11.76kg[/tex]
Step-by-step explanation:
Given
[tex]Field\ A= 56\%[/tex]
[tex]Field\ B= The\ rest[/tex]
[tex]Bag = 21kg\ feed[/tex]
Required
Determine how much goats in field A, get.
To do this, we simply multiply the percentage feed received by goats in field A by the actual bags of feeds
i.e.
[tex]Feeds = 56\% * 21kg[/tex]
Convert percentage to decimal
[tex]Feeds = 0.56 * 21kg[/tex]
[tex]Feeds = 11.76kg[/tex]
Hence, goats in field A get 11.76kg of feeds

solving the expression
[tex]\:\:\frac{4\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}=4\cdot \:\frac{\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}[/tex]
[tex]=4\:\frac{27x^3y^{12}}{16x^{12}y^{20}}[/tex]

Steve saw 313 birds during a bird-watching trip to Yellowstone National Park. He observed 15 more trumpeter swans than sand-hill cranes. He saw twice as many mountain chickadees as dusky grouses. How many birds of each type did Steve observe if he saw half as many trumpeter swans as dusky grouses?
Answers
Answer:
trumpeter swans = t = 41
sand-hill cranes = s = 26
chickadees = c = 164
dusky grouses = d = 82
Step-by-step explanation:
Total birds = 313
Let
trumpeter swans = t
sand-hill cranes = s
chickadees = c
dusky grouses = d
t = 15 + s
c = 2d
d = 2t
t + s + c + d = 313
(15+s) + s + 2d + d = 313
15 + s + s + 2(2t) + 2t = 313
15 + 2s + 4t + 2(15+s) = 313
15 + 2s + 4(15 + s) + 30 + 2s = 313
15 + 2s + 60 + 4s + 30 + 2s = 313
105 + 8s = 313
8s = 313 - 105
8s = 208
s = 208 / 8
= 26
s = 26
t = 15 + s
= 15 + 26
= 41
d = 2t
d = 2(41)
= 82
c = 2d
c = 2(82)
= 164
trumpeter swans = t = 41
sand-hill cranes = s = 26
chickadees = c = 164
dusky grouses = d = 82

determine the equation of the quadratic function represented by the table of values below: x -4 -3 -2 -1 0 1 y -20 -13 -8 -5 -4 -5
Answers
Answer: y = -1*x^2 - 4
Step-by-step explanation:
A generic quadratic equation is written as:
y = a*x^2 + b*x + c
we need to find the values of a, b, and c
We have the table:
x y = f(x)
-4 -20
-3 -13
-2 -8
-1 -5
0 -4
1 -5
In the table we can see two things:
y(0) = a*0^2 + b*0 + c = c = -4
Then we know that:
y(x) = a*x^2 + b*x - 4
Now we only need to find a and b.
We also can see that we have symmetry around the point x = 0, this means that x = 0 is the vertex of the quadratic equation, and for a general case the vertex is at:
x = -b/2a
and this is equal to zero:
-b/2a = 0
then we must have b = 0.
So for now, the equation is:
y = a*x^2 -4
Now we can just replace the values of any of the points to find the value of a, for example we can use the point (1, -5)
this means that:
y = -5 = a*1^2 - 4
-5 = a - 4
-5 + 4 = a
-1 = a
Then the quadratic equation is:
y = -1*x^2 - 4

Answers
Answer:
The line has a slope of zero which means the line is a horizontal line.
Step-by-step explanation:
Given that:
The two points are (-3,2) and (4,2)
Slope of a line is given by the formula,
[tex]m = \frac{Rise}{Run} = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
Here,
[tex]x_{1}=-3,\ y_{1}=2\\x_{2}=4,\ y_{2}=2[/tex]
Putting these values in formula;
[tex]m=\frac{2-2}{4-(-3)} \\m = \frac{0}{4+3}\\m = \frac{0}{7} = 0[/tex]
Hence,
The line has a slope of zero which means the line is a horizontal line.
