To the nearest cent, how much interest will she earn in 2 years?
Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answers
Answer:
10.50 is the interest
Step-by-step explanation:
B = p(1 + r)^t
P = 50
r = .10
t = 2
B = 50(1 + .1)^2
= 50(1.1)^2
= 50(1.21)
= 60.5
But we want to know the interest and this is the balance
60.5- 50 = 10.5

What is the residual of a regression equation?A residual is the difference between the observed y-value (from scatter plot) and the predicted y-value (from regression equation line). It is the vertical distance from the actual plotted point to the point on the regression line.
Given here function g plots the model more accurately than function f thus this can only be when function f has more residuals because g plots the model more accurately.

Kari estimated the quotient of Negative 12 and one-fifth divided by 4 and two-fifths to be –8. Which best describes her error? Kari multiplied the compatible numbers –12 and 4. Kari found that the quotient of a negative number and a positive number is negative. Kari found that the quotient of a positive number and a negative number is positive. Kari added the compatible numbers –12 and 4.
Answers
Answer:
D. Kari added the compatible numbers –12 and 4.
Step-by-step explanation:
Our numbers are [tex]-12\frac{1}{5}[/tex] and [tex]4\frac{2}{5}[/tex]. We want to find Kari's error. Let's look through the answer choices and try them out:
A: "Kari multiplied the compatible numbers –12 and 4"
Well, if we multiply -12 by 4, we get -48, which is very different from -8, so A cannot be right.
B: "Kari found that the quotient of a negative number and a positive number is negative"
This is actually a true statement because whenever we multiply or divide a positive number and a negative number, the result is always negative. So, this isn't an error. B is wrong.
C: "Kari found that the quotient of a positive number and a negative number is positive"
If B is a true statement, C must be false - and that's right: it is false because the quotient of a positive number and a negative number is always negative not positive. Eliminate C.
D: "Kari added the compatible numbers –12 and 4"
What do we get if we add -12 and 4? We get: -12 + 4 = -8, which is exactly the number that Kari got. So instead of dividing, Kari accidentally added and got -8, which is the wrong answer. Thus, D is correct.
Answer:

In the past twenty years, scientists have seen the sea level rise at a rate of approximately 0.13 inches per year. If this rate continues, which best represents the change in sea level over the next 27 months (2.25 years)?
Answers
Answer:
The change in the sea level will be by 0.2925 inches
Step-by-step explanation:
First of all , we will need to write out the rate at which the sea level is rising. This is 0.13 inches, per year. This means that every year, the sea level increases by 0.13 inches.
Since the sea level increases by 0.13 inches every year, in 2.25 years, to get the sea level, we will have to multiply the current rate at which it is rising by that duration of time.
This will be 2.25 years X 0.13 inches/ year = 0.2925 inches
Therefore, the change in the sea level will be by 0.2925 inches
Answer:
0.2925 inches

these 15 colored pencils make up 20% of jordon's colored pencil collection.how many colored pencils does jordon have in his collections
Answers
Answer:
75 coloured pencils
Step-by-step explanation:
Let's say Jordon has x total pencils.
We know that 20% of these x pencils is 15, so we have:
20% * x = 15
Remember that % is just "out of 100", so 20% = 20/100 = 0.20. Then:
0.20x = 15
x = 15 / 0.20 = 75
Jordon has 75 coloured pencils.
Answer:
75 pencils
Step-by-step explanation:
Let the total no. of pencils be T
20% of T = 15
20/100 × T = 15
T = 15 × 100/20
T = 15 × 5
T = 75

Step-by-step explanation:
We have a right triangle with hypotenuse 10 and the height 8. Either the one on the left or the one on the right
We can find the base using the Pythagorean theorem
a^2 + b^2 = c^2
a^2 +8^2 = 10^2
a^2 +64 = 100
Subtract 64 from each side
a^2 = 100 -64
a^2 = 36
Take the square root of each side
a = 6
Now a is 1/2 of the total base of the big triangle. It is identical since the triangles are equal
x = 2 * a
x = 2*6 = 12
Answer:
x = 12
Step-by-step explanation:
Consider the right angle triangle with
base: x/2
height: 8
hypotenuse: 10
Using pythagoras theorem
10² = 8² + (x/2)²
(x/2)² = 100 - 64
(x/2)² = 36
x/2 = 6
x = 12
Fiona draws a circle with a diameter of 14 meters. What is the area of Fiona’s circle?
Answers
Answer:
The area of the circle is [tex]153.94meters^2[/tex]
Step-by-step explanation:
The formula for the area of a circle is : [tex]\pi *radius^{2}[/tex]
To work this out you would first need to divide the diameter of 14 by 2, this gives you 7. This is in order for us to calculate the radius. The radius of a circle is the length from one side to the centre.
Now that we know the radius the next step is to multiply pi by the radius of 7 squared, this gives you 153.94. This is because in order for you to calculate the area you would substitute the values into the formula.
1) Divide 14 by 2.
[tex]14/2=7[/tex]
2) Multiply pi by 7 squared.
[tex]\pi *7^2=153.94 meters^2[/tex]
153.94 square meters is the area of the triangle.
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
The formula to calculate the area of a circle is A = πr², where A is the area and r is the radius of the circle.
Since the diameter is given as 14 meters, the radius can be calculated by dividing the diameter by 2:
r = d/2 = 14/2 = 7 meters
Now, we can substitute this value of radius into the formula for the area of a circle:
A = πr² = π(7)² = 49π square meters
Therefore, the area of Fiona's circle is 49π square meters (or approximately 153.94 square meters if π is approximated to 3.14).
