13×10=130
13-10=3
13 and 10 is the answer
Answer: the interest is $8137.8
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = $62,604.18
r = 13% = 13/100 = 0.13
n = 1 because it was compounded once in a year.
t = 1 year
Therefore,.
A = 62604.18(1 + 0.13/1)^1 × 1
A = 62604.18(1.13)
A = $70742.7
Her interest would be
70742.7 - 62604.18
= $8137.8
Answer:
48 cubes can be cut from the wooden cuboid
Step-by-step explanation:
Total calculate this, we will first of all find the volume of the cuboid, and the volume of the cubes to be cut, then divide the volumes to see how many cubes can be cut from the cuboid.
Volume of cuboid = 12 × 12 × 9 = 1296 cm
volumes of each cube to be cut = 3 × 3 × 3 = 27 cm
Next, we will divide the volume of cuboid by the volume of the cubes:
Number of cubes = Volume of cuboid ÷ volume of cubes
Number of cubes = 1296 ÷ 27 = 48 cubes
Therefore, 48 cubes of sides 3cm can be cut from the wooden cuboid
area of trapezoid is 1500 & represented with expression 
. Correct answer is c) .
<u>Step-by-step explanation:</u>
Here we have , a Trapezoid in figure. A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel . A trapezoid:
-
has a pair of parallel sides
- is an isosceles trapezoid when it has equal angles from a parallel side
-
is called a "trapezium" in the UK
Area of Trapezoid = 
, a & b are the parallel sides and , h is height of trapezoid . Let's find area of Trapezoid:
⇒ 
⇒
⇒ 
⇒ 
⇒ 
So, area of trapezoid is 1500 & represented with expression . Correct answer is c) .
Answer: 280
=======================================
Explanation:
x = number of downloads for standard version
If x is the number of standard version, then 3*x is the number of the high quality versions because there are 3 times as many HQ versions than standard.
2.7*x represents the total size of all the standard versions, 4.5*3x = 13.5x is the total size of the HQ versions. Combined, we have 2.7x+13.5x = 16.2x as the overall size of all the downloads (standard+HQ).
Set this equal to 4536 and solve for x
16.2x = 4536
16.2x/16.2 = 4536/16.2
x = 280
