Answer:
1,970
Step-by-step explanation:
The amount earning Elisa Harrington for July through October were 2,087 1,912 1,876 2,005
The formula for Average amount can be calculated as:.
Sum of Amount/Number of terms
Number of terms = 4
Hence:.Average Amount =
2,087 + 1,912 + 1,876 + 2,005/4
= 7,880/4
= 1,970
Therefore, the average amount Elisa was earning was 1,970

Answer:
300 nickels
Step-by-step explanation:
Reading the question, someone has 435 nickels and dimes.
The total is $28.50.
You're trying to find how many nickels he has.
All you need to do is set up a system of equations.
I'm going to use x as the number of nickels and y as the number of dimes.
Based on the question, you can say that
x + y = 435
(the number of nickels and dimes have t equal 435)
and 0.05x + 0.1y = $28.50
(nickels are 5 cents and dimes are 10 cents)
You want to solve for x, the number of nickels.
You can manipulate the first equation by subtracting x on both sides.
After you do that, you will get y = 435 - x. Now, you can substitute this equation into the second one.
First, you can distribute the 0.1.
0.05x + 0.1(435 - x) = 28.50
Then, you can put the two x's together.
0.05x + 43.5 -0.1x = 28.50
Next, you can subtract 43.5 on both sides to isolate x.
-0.05x + 43.5 = 28.50
Finally, you can divide on both sides to get x, which is the number of nickels.
-0.05x = - 15
x = 300 nickels

Find f(5)
Answer:
f(5) = 2
Step-by-step explanation:
To evaluate f(5), that is when x = 5 in the interval x ≥ 5
then
f(5) = 6x - 28 = 6(5) - 28 = 30 - 28 = 2, so
f(5) = 2
Andrew wants to run ten miles in three days .He ran 212 miles on Monday and 425 miles on Tuesday how many miles does Andrew need to run on Wednesday?
Answer: 3.63 miles
Step-by-step explanation: I think you meant to type 2.12 and 4.25 so I'm just going to go by that. To figure out how many more miles he needs to run, you add the amount he already ran together, and then subtract that from his goal. 4.25 plus 2.12 equals 6.37. 10 minus 6.37 equals 3.63. He needs to run 3.63 miles on Wednesday, in order to reach his goal of 10 miles.

Answer:
14.65
9.2
Step-by-step explanation:
For this question I will be using SOH CAH TOA and I will assume that you know that that means
For the first use I have the adjacent side and need to solve for the hypotonouse which means I will be using CAH
which means that cos35=12/x
solve for x and get 14.65
For the second one I have the opposite side and need the adjacent so I will use TOA
Tan41=8/x
I will do the same thing for the last one and get x=9.2

Factorise the given expressions :
a) (6p2 – 36p + 30) b) (256 − 64y + 4y2
)
Answer:
a) Factorizing [tex]6p^2 - 36p + 30[/tex] we get [tex]6(p-5)(p-1)[/tex]
b) Factorizing [tex]4y^2-64y+256[/tex] we get [tex]4(y-8)(y-8)[/tex]
Step-by-step explanation:
Factorise the given expressions :
a) [tex]6p^2 - 36p + 30[/tex]
First we take 6 common:
[tex]6p^2-36p+30\\=6(p^2-6p+5)\\=6(p^2-5p-p+5)\\=6(p(-5)-1(p-5))\\=6(p-5)(p-1)\\[/tex]
So, factorizing [tex]6p^2 - 36p + 30[/tex] we get [tex]6(p-5)(p-1)[/tex]
b) [tex]256 -64y + 4y^2[/tex]
Rearranging terms:
[tex]4y^2-64y+256[/tex]
Taking 4 common
[tex]4(y^2-16y+64)\\4(y^2-8y-8y+64)\\4(y(y-8)-8(y-8))\\4(y-8)(y-8)[/tex]
So, factorizing [tex]4y^2-64y+256[/tex] we get [tex]4(y-8)(y-8)[/tex]

what is the slope and the point based on the equation: (y-2) = 5(x - 4)
Answer:
Slope = 5
Point = (4, 2)
Step-by-step explanation:
Slope: 5
Step-by-step explanation:
This is called point slope form. y-y1=m(x-x1)
If m is slope then your slope is 5

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
-6x + 5y = 34
-6x - 10y = 4
Step 2: Rewrite Systems
-6x + 5y = 34
Multiply everything by -1: 6x - 5y = -34Step 3: Redefine Systems
6x - 5y = -34
-6x - 10y = 4
Step 4: Solve for y
Elimination
Combine 2 equations: -15y = -30Divide -15 on both sides: y = 2Step 5: Solve for x
Define equation: -6x - 10y = 4Substitute in y: -6x - 10(2) = 4Multiply: -6x - 20 = 4Add 20 on both sides: -6x = 24Divide -6 on both sides: x = -4After 50 years, Helena's age will be three times her age now. How old is Helena now?

A portion of a map with cities a and b is shown.The map uses a scale of 1 inch to 30 miles. A new map has a scale of 2 inches=15 miles. How far apart are cities a and b
Answer:
22.5miles
Step-by-step explanation:
For Map 1;
1 inches = 30miles
For Map 2:
2 inches = 15miles
1 inches = x
2x = 1 *15
x = 15/2
x = 7.5miles
This means that 1 inch represents 7.5miles on Map 2'
The distance between the two cities in miles = 30miles - 7.5miles
The distance between the two cities (in miles) = 22.5miles

James Bond is rappelling down a cliff face to infiltrate an enemy base, but there is a gust of wind, and he starts swinging side to side. If he makes a 45 m pendulum once you factor in the length of the rope, how long does it take for him to complete a full oscillation? He'll need to know this so that he can time his distraction of the guards
Answer:
13.46 s
Step-by-step explanation:
The time it takes James Bond to complete one full oscillation is the period of a pendulum of length, l which is, T = 2π√(l/g) where l = length of pendulum = length of rope = 45 m and g = acceleration due to gravity = 9.8m/s²
So, substituting the values of the variables into the equation, we have
T = 2π√(l/g)
= 2π√(45 m/9.8m/s²)
= 2π√(4.592s²)
= 2π × 2.143
= 13.46 s
So, it takes 13.46 s for him to complete one full oscillation.
