Answer:
x = y^2
:
Find the numbers if both are positive and their sum is 12
x + y = 12
replace x with y^2, you have a quadratic equation
y^2 + y - 12 = 0
Step-by-step explanation:
Factors to
(y+4)(y-3) = 0
The positive solution is all they want here
y = 3
then
x = 3^2
x = 9
;
they add up to 12

The world population was 6.114 billion in 2000 with an estimated growth
rate of 1.9% per year. Assuming the world population follows this exponential
growth mode, find the projected population in 2030.
Answer:
10.754 billion
Step-by-step explanation:
this is a exponential growth question. the initial value is 6.114 billion, with a growth rate of 1.9%, and 30 years. after you plug the values into the exponential growth equation, you should get 10.754 billion.

Carla and Deserea bought a dozen cookies from the bakery. Carla ate ¼ of the cookies and Deserea ate ½ of the cookies. Who ate the most?
Answer:
Deserea ate more
Step-by-step explanation:
One dozen equals 12
Carla ate 1/4 of it
1/4×12/1=3
Carla ate 3 cookies
Deserea ate 1/2
1/2×12/1=6
Deserea ate 6
6 is greater than 3 so Deserea ate more

20m + on ?
Which expression is equivalent to 54n
Answer:
Choice A, 20(3n-m)
Step-by-step explanation:
First, lets combine like terms for the question 54n - 20m + 6n,
60n - 20m.
Next, lets rule out the choices that are visibly wrong. This includes Choice B, because it wouldn't equal what is above and Choice C, as it ignores unlike terms.
Now, it is down to Choices A and D. Let's use the distributive property to simplify these options.
Choice A:
20(3n-m)
60n-20m
Choice D:
20(m-3n)
20m-60m
With this, it can be concluded that the correct answer is Choice A since it equals 60n-20m, which is equal to the original question when like terms are combined.
Answer:
Which inequality has the solution set shown on the graph?
-54n < 1080
-54n > 1080
594 > -11n <<<<<This one
594 < -11n

PLS HELP :) Which expression is equivalent to c+c-10?
2c−10
−8c
c−9
12c
Answer:
2c - 10
Step-by-step explanation:
When you combine the like terms of the expression c+c-10, you get 2c-10.
Therefore, 2c - 10 is equivalent to c + c - 10.
c + c - 10 → 2c - 10.

A circle has a diameter of 16 inches. What is the circumference of the circle using function on the calculator?
Answer: 50.26548 (50.27)
Step-by-step explanation:
Circumference = 2 x π x r(radius)
Diameter = 2 x r(radius)
C = π x 16 = 50.26548

In circle D with m \angle CDE= 122m∠CDE=122 and CD=6CD=6 units, find the length of arc CE. Round to the nearest hundredth.
Answer:
12.78 units
Step-by-step explanation:
The formula for arc length =
2πr × θ/360
From the question:
θ = 122°
r = 6 units
Therefore, the arc length =
2 × π × 6 × (122/360)
= 12.775810125 units
Approximately to the nearest hundredth = 12.78 units
Therefore, the length of arc CE is 12.78 units

When Theo was born his uncle put $1000 in a college savings account for him, at 4%
interest
- Develop a function to show the amount in the savings account after x years
- How much money will be in the account when Theo is 18 and ready for college?
Answer:
A= P(1+r)^x
$2025
Step-by-step explanation:
Given data
Principal= $1000
Rate= 4%
1. - Develop a function to show the amount in the savings account after x years
Time= x years
The function is
A= P(1+r)^x
2. How much money will be in the account when Theo is 18 and ready for college?
Time= 18 years
A= 1000(1+0.04)^18
A=1000(1.04)^18
A=1000*2.025
A=$2025
