Alyssa opened a bank account that earns 1.5% simple interest. Over 4 years, she earned $72 in interest. How much money did
she initially deposit into the bank account?
Answer:
1200
Step-by-step explanation:
72/4=$18 interest each year
amount x interest rate = interest
amount x .015 = 18
amount = 18/.015
amount = 1200
find the value of x.
Answer:
139 degrees
Step-by-step explanation:
we only have a central angle here (angle at the center of the circle).
and that angle remains the same along these 2 lines all the way out to the circle arc (and beyond, wherever these 2 lines take us).
so, if there is nothing missing in this graph, then x is the same as the inner angle : 139 degrees
In a test, +3 marks are given for every correct answer and -1 are given for every incorrect answer (i) Sona scored +20 marks though she got 10 correct answers. How many incorrect answers has she attempted??
Answer:
10 incorrect answers
Step-by-step explanation:
Correct answer = +3
Incorrect answer = - 1
Mark scored = 20
Number of correct answers = 10
Let:
Incorrect answers = y
Hence, we can fashion out the expression for total score :
(Number of correct answers * score per Correct answer + number of incorrect * score per incorrect) = total score
(10 * 3) + (y * - 1) = 20
30 - y = 20
-y = 20 - 30
-y = - 10
y = 10

A honeydew melon is shaped like a sphere with a diameter of 8 inches. Which value is closest to the volume of the melon?
Answer:
The volume of sphere = 268.08
Step-by-step explanation:
Below is the calculation for the volume of melon (sphere).
Given the diameter of the sphere is = 8 inches
Now find the radius by dividing the diameter by 2 = 8/2 = 4 inches
Now use the below formula to find the volume.
The volume of sphere = [tex]\frac{4}{3} \times \pi \times r^{3}[/tex]
The volume of sphere = 268.08

Assuming exponential function has a starting value of 360 and a decay rate of 73% write an equation to model the situation
Answer:
a = 360 * 0.27^n
Step-by-step explanation:
a = 360 * (1 - .073)^n
a = 360 * 0.27^n
What is the value of y in the equation 5x + 2y = 20, when x = 0.3?
Answer:
y=9.25
Step-by-step explanation:
5x+2y=20
5(.3)+2y=20
1.5+2y=20
2y=20-1.5
2y=18.5
y=18.5/2
y=9.25

What is the area of this polygon?
___ units2
If you can please explain with you answer!! Thank you so much!
Answer:
39 units
Step-by-step explanation:
area of polygon = area of rectangle VERD + area of triangle MVR
[length of rectangle (6) * width of rectangle (5)] + [1/2 * 3 (height of triangle) * 6 (height of triangle)] = area of polygon
(6*5) + (1/2*3*6) = area of polygon
30 + 9 = area of polygon
area of polygon = 39

An ice cream shop has a sign in their window that says, "We sell 12,000 scoops per month." The number of scoops has been rounded. Which could be the number of scoops sold if they rounded to the nearest thousand? Choose all answers that apply
Answer:
B - 12,111
C - 11,589
Step-by-step explanation:
Here are the options
A - 10, 999
B - 12,111
C - 11,589
In order to round off to the nearest thousand, look at the hundred figure, if the number is greater or equal to 5, add 1 to the thousand figure. If this is not the case, add zero. Replace all the figures before the thousand figure with zero. i.e. the hundred ten, unit
Rounding off 10,999 to the nearest thousand is 11,000
the hundred figure is greater than 5, so one is added to the thousand figure. The
Rounding off 12,111 to the nearest thousand is 12,000
the hundred figure is less than 5, so zero is added to the thousand figure.
Rounding off 11,589 to the nearest thousand is 12,000
the hundred figure is equal to 5, so one is added to the thousand figure.
Arithmetic and Geometric Sequences
1. Consider the sequence: 3, 7, 11, 15...
Find an explicit formula for the n-th term of this sequence.
Answer:
Step-by-step explanation:
This is arithmetic since adding 4 to each term gets us to the next term in the sequence. That means that the common difference, d, is 4. The general arithmetic explicit formula is
[tex]a_n=a_1+d(n-1)[/tex] and using the info given when a1 = 3 and d = 4:
[tex]a_n=3+4(n-1)[/tex] or, if you want to make it easier to deal with:
[tex]a_n=4n-1[/tex] (I just distributed through the parenthesis and then combined like terms. As you can see, arithmetic sequences are linear).

B.-3 3/8
