Find the interest
earned:
$26,000 for 36 months
at 7.5% annual
compound interest
Answer:
Interest = $6,300 (Approx.)
Step-by-step explanation:
Given:
Amount deposit (P) = $26,000
Number of month = 36 month
Number of year (n) = 36 / 12 = 3 year
Rate of interest (r) = 7.5% = 0.075
Find:
Interest earned
Computation:
Interest = p[(1+r)ⁿ-1]
Interest = 26,000[(1+0.075)³-1]
Interest = 26,000[(1.075)³-1]
Interest = 6,299.71
Interest = $6,300 (Approx.)

Is the amount of sugar you need proportional to the amount of lemonade mix you use?
Cups of sugar ∝ Number of packets
C ∝ N
C = k/N
k = C/N
a) For
1/3 cups of sugar and 1 packet of Lemonade mix
1/3 ∝ 1
1/3 = 1k
k = 1/3/1
k = 1/3
b) For
1 cups of sugar and 3 packets of Lemonade mix
1 ∝ 3
1 = 3k
k = 1/3
k = 1/3
c) For
3 cups of sugar and 9 packets of Lemonade mix
3 ∝ 9
3= 9k
k = 3/9
k = 1/3
Therefore, Yes, the amount of sugar you need proportional to the amount of lemonade mix you use. This is because the value is k is the same

The total cost of a pair of shoes and a hoodie is $150 the hoodie cost $100 more than the pair of shoes how much does each item cost?
Answer:
shoes = $25
hoodie = $125
Step-by-step explanation:
total cost = $150
hoodie = x + 100
shoes = x
x + x + 100 = 150
2x = 150 - 100
x = 50/2
x = 25
shoes = $25
hoodie = $125
add them up and u get the price of the shoe 125+25= $150
1. By what factor did the medicine decrease in the first hour and a half? Explain how you know.
Answer:
4/9
Step-by-step explanation:
At t = 0 ; volume = 270
At t = 1.5 ; volume = 80
y = P(1 - r)^t
y =ab^x (exponential)
a = initial amout at t = 0
y = final amount
t = 1.5
80 = 270b^t
80/270 = b^t
8/27 = b^1.5
8/27 = b^3/2
b^3/2*2/3 = (8/27)^2/3
Cube root of 8/27 = 2/3
Square of 2/3 = (2/3)^2 = 4/9

Find the volume of a right circular cone that has a height of 2.7 ft and a base with a diameter of 14.4 ft. Round your answer to the nearest tenth of a cubic foot.
Answer:
20.4 cubic feet
Step-by-step explanation:
formula for the volume of a cone is (r^2xhxpi)/3
so, r= 14.4/2
(7.2x2.7xpi)/3
The volume of a right circular cone is 146.49 cubic foot.
What is the volume of a right circular cone?The Volume of Right Circular Cone formula is defined as The volume of a cone is one-third of the product of the area of the base and the height of the cone.
The volume of a right circular cone is given by;
[tex]\rm Volume=\dfrac{1}{3}\pi r^h\\\\r = radius, \ h = height\\[/tex]
The volume of a right circular cone that has a height of 2.7 ft and a base with a diameter of 14.4 ft.
The radius of the cone is;
[tex]\rm Radius=\dfrac{diameter}{2}\\\\ Radius=\dfrac{14.4}{2}\\\\ Radius=7.2[/tex]
The volume of a right circular cone is;
[tex]\rm Volume=\dfrac{1}{3}\pi r^h\\\\ Volume=\dfrac{1}{3}\times 3.14 \times (7.2)^2\times 2.7\\\\Volume=146.49[/tex]
Hence, the volume of a right circular cone is 146.49 cubic foot.

If the sequence 4, 8, 12, 16 continues, what will be the 7th
term?
Answer:
28
Step-by-step explanation:
In order to find the seventh term in this arithmetic function, you need to find its function; in order to do this, you must first identify the common difference by finding the difference between two consecutive terms:
16 - 12 = 4; the common difference is 4
Now, you need to find the 0th term, which is the 1st term minus the common difference:
4 - 4 = 0
At this point, you can write out the function (where f(n) = [0th term] + [common difference]n:
f(n) = 4n
Finally, you can plug 7 into this function:
f(n) = 4(7)
f(n) = 28, so the 7th term is 28
