At what percent rate of compound interest p.a will the compound interest on rs343000be rs169000 in 3 years
Answer:
The money was invested at an interest of 14.28% per year.
Step-by-step explanation:
To determine at what percent rate of compound interest per year will the compound interest on $ 343000 be $ 169000 in 3 years, the following calculation must be performed:
343,000 x (1 + X / 1) ^ 3x1 = 343000 + 169000
343,000 x 1 + X ^ 3 = 512,000
1 + X ^ 3 = 512,000 / 343,000
1 + X ^ 3 = 1.4927
1 + 0.14286 ^ 3 = 1.4927
1.4927 = 1.4927
X = 0.14286 x 100 = 14.28%
Therefore, the money was invested at an interest of 14.28% per year.
A force of 68 N is applied to an area of 540 cm2. Calculate the pressure in N/m2. Give your answer to the nearest integer.
Answer:
[tex]P=1259.26N/m^2[/tex]
Step-by-step explanation:
From the question we are told that:
Force [tex]F=68N[/tex]
Area [tex]A=540cm^2=0.054m^2[/tex]
Generally the equation for Pressure is mathematically given by
[tex]P=\frac{F}{A}[/tex]
[tex]P=\frac{68}{0.054}[/tex]
[tex]P=1259.26N/m^2[/tex]

The histogram shows the number of laps completed by swimmers on a team during practice.
A. which interval contains the most values?
B. How many swimmers are on the team?
C. What percent of the swimmers swam more than 14 laps? Round o the nearest tenth of a percent.
Explain.
Answer:
A) 10-14
B) 45
C) 6.7%
Step-by-step explanation:
A) The interval that contain the most values can be gotten by looking at the histogram and selecting the interval with the highest frequency. Hence the interval 10-14 contains the most values because it has a frequency of 20.
B)The total number of swimmers is gotten by summing all the frequency of each individual lap. Hence:
Total swimmers on team = 10 + 12 + 20 + 0 + 3 = 45 swimmers
C) The percentage of swimmers who swam more than 14 laps = (number of swimmers that swam more than 14 laps/total swimmers) * 100%
The percentage of swimmers who swam more than 14 laps = [(0 + 3)/45] * 100% = (3/45) * 100% = 6.7%
What is the length of the diagonal of the square shown below?
5√2
Step-by-step explanation:
By the Pythagorean theorem,
A² + B² = C²
5² + 5² = C²
25 + 25 = C²
C² = 50
C = √50
C = √(2 • 25)
C = √2 x √25
C = √2 • 5
C = 5√2

A cylinder and a sphere both have the same radius, 4. The height of the cylinder is equal to the diameter of the sphere. Select the expression that describes the volume of the cylinder that is not occupied by the sphere.
Answer:
134.04 cubic units
Step-by-step explanation:
Step 1
Find the Volume of the Sphere
Formula = 4/3πr³
r= radius = 4
Hence,
Volume = 4/3 × π × 4³
= 268.08 cubic units
Step 2
Find the Volume of the cylinder
Formula = πr²h
r = radius = 4
h = Height = Diameter of the sphere
Radius of a sphere = 4
Diameter = Height of cylinder = 2 × r = 2 × 4 = 8
Hence: π × 4² × 8
= 402.12 cubic units
Step 3
The expression that describes the volume of the cylinder that is not occupied by the sphere = Volume of Cylinder - Volume of sphere
= 402.12 cubic units - 268.08 cubic units
= 134.04 cubic units
The expression that describes the volume of the cylinder that is not occupied by the sphere is 134.04 cubic units
We have given radius of sphere is 4
What is the formula for volume of the Sphere?[tex]V= 4/3\pi r^3[/tex]
r= radius
We have given that r=4
[tex]Volume = 4/3 \times \pi \times 4^3[/tex]
V= 268.08 cubic units
What is the formula for volume of the cylinder?[tex]Formula = \pi r^2h[/tex]
r = radius = 4
h = Height = Diameter of the sphere
Radius of a sphere = 4
Diameter = Height of cylinder
= 2 × r
= 2 × 4
= 8
Therefore we get
[tex]V=\pi \times 4^2 \times 8[/tex]
V= 402.12 cubic units
The expression that describes the volume of the cylinder that is not occupied by the sphere = Volume of Cylinder - Volume of sphere
= 402.12 cubic units - 268.08 cubic units
= 134.04 cubic units
Therefore the expression that describes the volume of the cylinder that is not occupied by the sphere is
(402.12 - 268.08) cubic units.

Answer:
THE ANSWER IS NOT C / 3
THE ANSWER IS "A"
Step-by-step explanation:
all the "hard" work is done (the numbers)...
lets start with the "units" at the end of the problem you have to have mm/day... so just start crossing out "top to bottom" when you see the same unit on the top and bottom... if you se day in the numerator and day in the denominator cross them out...
Do that and the one that has mm on the top and day on the bottom is the answer...
Step #2 ... two of the answers have that ... so now look for "silly fractions"
something like 1 year/ 999 days... your problem does not have totally silly things like that , but the WRONG answer has 1mm/ 10 cm (or something like that ) there is 10 mm in 1 cm, you choices has that opposit in one answer.

Answer:
∠ 1 = 53°, ∠ 2 = 37°
Step-by-step explanation:
let ∠ 2 be x then ∠ 1 = x + 16
Complementary angles sum to 90° , then
x + 16 + x = 90
2x + 16 = 90 ( subtract 16 from both sides )
2x = 74 ( divide both sides by 2 )
x = 37
Then
∠ 2 = 37° and ∠ 1 = 37 + 16 = 53°

Match each function with its impact
Answer: g(f)= 2f - The input is f
h(g)=-4+g - The input is g
f(h)=h-7 - The input is h
Step-by-step explanation:
The matches are:
h(g) = -4 + 9 corresponds to input g.
f(h) = h - 7 corresponds to input h.
g(t) = 21 corresponds to input t.
We have to given that,
To Match each function with its input.
h(g) = -4+9
The input is f.
f(h) = h - 7
The input is h.
g(t) = 21
The input is g.
Now, We get;
h(g) = -4 + 9 corresponds to input g.
f(h) = h - 7 corresponds to input h.
g(t) = 21 corresponds to input t.
So the matches are:
h(g) = -4 + 9 corresponds to input g.
f(h) = h - 7 corresponds to input h.
g(t) = 21 corresponds to input t.

I’m the parallelogram above, what is the value of x+y
Help please
Answer:
x + y = 248
Step-by-step explanation:
Using the property : Sum of co- interior angles = 180
[tex]\angle y + 56 = 180\\\\\angle y = 180 - 56 = 124\\\\\angle x + 56 = 180\\\\\anle x = 180 - 56 = 124\\\\\angle x + \angle y = 124 + 124 = 248^\circ[/tex]
The value of 'x' and 'y' are 124° and 124°, respectively. Thus, the value of the expression x + y will be 248°.
What is a parallelogram?It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides and angles are parallel and equal.
According to the definition, the value of 'x' and 'y' will be equal.
And the sum of adjacent angles will be 180 degrees. Then the equation is given as,
x + 56° = 180°
x = 124°
The sum of 'x' and 'y' is given as,
x + y = 124° + 124°
x + y = 248°
