Answer:
15
Step-by-step explanation:
2x/2y = 16
First, we can cancel out the 2s as there is one on the numerator and another on the denominator.
x/y = 16
To make it fraction form, we know that 16 = 16/1.
x/y = 16/1
We then get x and y.
x = 16
y = 1
x - y = 15
Find the sum, if it exists, of the infinite geometric series = 102+112. 2+123. 42+…
Answer:
it does not exist
Step-by-step explanation:
if it is a geometric sequence, there must be a common ratio or multiplication factor between neighboring terms :
102 × r = 112.2
r = 112.2/102 = 1.1
is 112.2 × 1.1 = 123.42 ?
yes.
so, it is a geometric sequence with the common ratio of 1.1.
the problem is now : the ratio is > 1.
that means the sequence tends are growing, and growing, and the sum is therefore rather "exploding" than converging.
for the sum to converge to a specific number the individual terms need to get smaller and smaller in absolute numbers.
with r > 1 this is impossible, so there is no sum for this sequence (with n going to infinity, so does the sum, and as "infinity" is not a value per se, the sum does not exist).
Find the circumference of the circle. You must show all work to get full credit. Don't forget to label your answer. Round to the nearest hundredth.
Answer:
The circumference is 26.38 yards
Step-by-step explanation:
The formula for finding the circumference of a circle is 2π(r). 2 times pi times the radius. We see that the radius is 4.2 yards, so we plug 4.2 into the variable labeled "r"
2 (3.14) (4.2) = 26.376
26.376 rounded to the hundredths place is 26.38

A ball has a diameter of 6 inches. A smaller ball has a radius of 2 inches. What is the approximate difference between the volume of the two balls
The difference between the volumes is 79.55 cubic inches.
What is the difference between the volumes?The volume of a sphere of radius R is:
[tex]V = (4/3)*3.14*R^3[/tex]
Here we have two spheres, the larger has a diameter of 6 inches, so its radius is:
R = 6in/2 = 3in
The smaller ball has a radius of 2 in.
Then the difference between the volumes is:
[tex]V = (4/3)*3.14*( (3in)^3 - (2in)^3) = 79.55 in^3[/tex]

Answer:
Since we know that each of the three triplets are the same age we can put next to n, 3.
And given that another child is 14 years old we can put that next to the "+" sign.
In total, it would equal 32, so put the 32 after the equal sign.
It should look like this:
3n + 14 = 32
But now they want us to solve for the triplet's ages, so we just solve for n;
3n + 14 = 32
-14 -14
3n = 18
/3 /3
n = 6, the triplet's ages are 6 years old each.

1. Weather Forecasting
2. Sales Forecasting
explanation
Weather Forecasting : the individual might question themselves about what the weather is gonna look like the day . is it gonna rain ? should I bring an umbrella ? should i take the car to work just incase it starts raining , or should I walk on foot and enjoy the hot sun?
Many retailers use probability to forecast the possibility of selling a specific amount of products on a given day, week, or month. This allows companies to forecast how much stock they will require in the future. A company, for example, may use a forecast model that claims it has a 90% chance of selling at least 100 items on a given day. To avoid running out of items to sell, keep at least 100 (preferably more) on hand at all times.

at the same rate. Assume that the initial profit from the store in town B is the same as the initial profit from the store ir

O 65%
O 96%
104%
154%
Mark this and retium
Answer:
96%
Step-by-step explanation:
he rigth equation to anticipate the profit after t years is p(t) = 10,000 (1.075)^t
So, given that both
store A and store B follow the same equations but t is different for them, you can right: Store A: pA (t) 10,000 (1.075)^t
Store B: pB(t'): 10,000 (1.075)^t'
=> pA(t) / pB(t') = 1.075^t / 1.075^t'
=> pA(t) / pB(t') = 1.075 ^ (t - t')
And t - t' = 0.5 years
=> pA(t) / pB(t') = 1.075 ^ (0.5) = 1.0368
or pB(t') / pA(t) = 1.075^(-0.5) = 0.964
=> pB(t') ≈ 0.96 * pA(t)
This means that the profit of store B is about 96%of the profit of store A at any time after both stores have opened.

Solve the following system of equations.
Answer:
n= -6, a= 5
Step-by-step explanation:
Label the two equations:
a= -2n -7 -----(1)
-3a +n= -21 -----(2)
Substitute (1) into (2):
-3(-2n -7) +n= -21
Expand:
-3(-2n) -3(-7) +n= -21
6n +21 +n= -21
Simplify, minus 21 on both sides:
7n= -21 -21
7n= -42
Divide both sides by 7:
n= -42 ÷7
n= -6
Substitute n= -6 into (1):
a= -2(-6) -7
a= 12 -7
a= 5

mr castle shares out 56 marbles between emily and asif in the ratio of 7:1 how many does each child get?
Answer:
Emily = 49
Asif = 7
Step-by-step explanation:
Let's take the number of marbles given to asif = x
Then, the marbles got by Emily will be 7 times that of asif 7x
Then,
7x + 1x = 56
8x = 56
x = 56/8
x = 7
So, number of marble asif got = x = 7
And number of marbles Emily got = 7x = 7 * 7 = 49

Two sides of the rectangle differ by 3. 5 cm find the dimension of the rectangle if its perimetre is 67cm
Answer:
Step-by-step explanation:
Two sides of the rectangle differ by 3.5 cm means that one side is 3.5 cm more than the other side.
If width = x cm, then length = x + 3.5
Perimeter = 67 m
2*(length +width) = 67
2*(x + 3.5 + x) = 67
2*(2x + 3.5) = 67
2*2x + 2*3.5 = 67
4x + 7 = 67
4x = 67 - 7
4x = 60
x = 60/4
x = 15 cm
Width = 15 cm
Length = 15 + 3.5
= 18.5 cm

Write down the next two terms of this pattern :8,18,30,44,......
Answer:
60, 78
Step-by-step explanation:
To find a pattern, try experimenting.
Going from 8 to 18 is + 10
Going from 18 to 30 is + 12
Going from 30 to 44 is + 14
We see that we add 2 more extra than the term before (+10, +12, +14)
So, we just add 2 for the next 2 terms which will be +16 and + 18
which are 44 + 16 = 60
and 60 + 18 = 78
Answer:
im not sure but the pattern im seeing is adding by even numbers i could be wrong but I think the next two numbers are 60, and 78
Step-by-step explanation:
8 + 10 is 18
18+ 12 is 30
30 +14 is 44
so i did
44+16 and got 60
and 60 + 18 is 78.
