The investments are $ 4000 and $ 3000 in the respective accounts
What is Algebra ?The mathematical field of algebra assists in the depiction of problems or conditions as mathematical statements. It involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form a meaningful mathematical expression.
In the given question,
x = amount invested at 10 %
( 7000 - x ) = amount invested at 11 %
The total interest was $730 :
.10 (x) + .11 (7000-x) = 730
0.1 x + 770 - 0.11 x = 730
0.01 x = 40
x = 4000
Therefore, the amount invested in an account that pays 10 % per year is $ 4000.
Hence , the amount invested in an account that pays 11 % per year is
= ( 7000 - x ) = 7000 - 4000 = $ 3000.

A set contains the numbers 0,6,12 and 15. 2 different numbers are selected randomly from this set. What is the probability that the sum is greater than 12
Answer:
Step-by-step explanation:
To find the probability of the sum of two randomly selected numbers from a set being greater than 12, we need to first find the total number of possible combinations of two numbers and then count the number of combinations that result in a sum greater than 12.
The set contains four numbers, so there are 4 choose 2 possible combinations of two numbers, which is equal to (4! / (2! * (4 - 2)!)), or 6 combinations. These combinations are:
(0,6), (0,12), (0,15), (6,12), (6,15), (12,15)
Next, we'll count the number of combinations that result in a sum greater than 12. These combinations are:
(6,15), (12,15)
There are 2 combinations that result in a sum greater than 12.
Finally, to find the probability, we'll divide the number of favorable outcomes (combinations with a sum greater than 12) by the total number of outcomes (all possible combinations of two numbers), and express the result as a fraction:
probability = 2 / 6
Reducing the fraction, we get:
probability = 1 / 3
So, the probability that the sum of two randomly selected numbers from the set is greater than 12 is 1/3.
That's how you find the probability of the sum of two randomly selected numbers from a set being greater than a certain value. By counting the number of favorable outcomes and dividing by the total number of possible outcomes, you can find the probability of a certain event.
Riding equation of the line that has the same slope as 3X minus 2Y equals 12 in the same y-intercept as 5Y +21 equals 4X
The linear equation can be written as:
y = (3/2)*x - 21/5
How to write the linear equation?
A general linear equation can be written as:
y = m*x + b
Where m is the slope and b is the y-intercept.
First, we know that our line has the same slope than:
3x - 2y = 12
Rewriting that we will get:
3x - 2y = 12
3x - 12 = 2y
(3/2)x - 12/2 = y
So the slope of this line is (3/2).
And our lie has the same y-intercept as 5y + 21 = 4x
We can rewrite that to get:
5y = 4x - 21
y = (4/5)x - 21/5
The y-intercept is -21/5
Then the linear equation is:
y = (3/2)*x - 21/5

The ansewr is C
Answer: 523.3cm^3
Step By Step Explanation:-The volume of a sphere can be calculated using the formula:
V = (4/3) * π * r^3
where r is the radius of the sphere. The diameter of the sphere is 10 cm, so the radius is half of that, or 5 cm.
Substituting the radius into the formula, we get:
V = (4/3) * π * (5 cm)^3
= (4/3) * π * 125 cm^3
= approximately 523.6 cm^3
So, the closest measurement to the volume of the sphere in cubic centimeters is approximately 523.3 cm^3.

If the radius of one of the semicircles is 7 meters, what is the circumference of one of the semicircle? asap 70 Ponits!!!!!!!!!!
10.99 m
21.98 m
87.92 m
43.96 m
Answer:
The circumference of one of the semicircles with a radius of 7 meters would be approximately 21.98 meters.
Step-by-step explanation:
The circumference of a circle can be calculated using the formula:
C = 2πr
where C is the circumference, π (pi) is approximately equal to 3.14, and r is the radius of the circle.
For a semicircle with a radius of 7 meters, the circumference can be calculated as follows: Because the semicircle is a half circle, then:
C = (2πr)/2= 3.14 × 7 = 21.98 meters
So, the circumference of one of the semicircles with a radius of 7 meters would be approximately 21.98 meters.
Answer:
The circumference of one of the semicircles is 21.98 m.
Step-by-step explanation:
The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle.
A semicircle is half a circle, therefore the length of the curved part of the circumference of a semicircle is half the circumference of a circle: πr.
Given the radius of one of the semicircles is 7 m and π ≈ 3.14, the circumference of the semicircle is:
⇒ C = 3.14 · 7
⇒ C = 21.98 m
Ice cream is packaged in cylindrical gallon tubs. A tub of ice cream has a total surface area of 232.36 square inches.

6.75 inches
5.25 inches
3.375 inches
2.625 inches
If the diameter of the tub is 8 inches, then the height of gallon tube is, 5.25 inches
What is surface area ?Surface area is the sum of the areas of all the faces (or surfaces) of a three-dimensional object. It is a measure of how much area the surfaces of an object take up in two dimensions. The surface area of a solid can be found by adding up the areas of its faces.
The surface area of a cylinder can be expressed as:
SA = 2πr² + 2πr x h
where r is the radius of the cylinder, h is its height, and π is the constant pi (3.14).
The diameter of the tub is 8 inches, which means the radius is 4 inches. We are also given that the total surface area is 232.36 square inches.
So we can write:
232.36 = 2(3.14)(4²) + 2(3.14)(4)(h)
Simplifying and solving for h, we get:
232.36 = 100.48 + 25.12h
131.88 = 25.12h
h = 131.88/25.12
h ≈ 5.25 inches
Therefore, the height of the ice cream tub is approximately 5.25 inches.

A passenger train traveled 240 miles in the same amount of time it took a freight train to travel 160 miles. The rate of the freight train was 20 miles per hour slower than the rate of the passenger train. Find the rate of the passenger train.
The rate of the passenger's train is given as follows:
60 miles per hour.
What is the relation between velocity, distance and time?Velocity is distance divided by time, hence the following equation is built to model the relationship between these variables:
v = d/t.
For the passenger train, the equation is given as follows:
v = 240/t.
vt = 240
t = 240/v.
For the freight train, the velocity is 20 miles slower than for the passenger train, hence:
v - 20 = 160/t
v = 160/t + 20.
Replacing the first equation into the second, the rate of the passenger train is obtained as follows:
v = 160v/240 + 20
v = 2v/3 + 20
v/3 = 20
v = 60 miles per hour.
