When a number is decreased by 10% of itself, the result is 9. What is the number?
Answer:
10-10%
Step-by-step explanation:
Think of it like this, 100% - 10% is 90%. But instead of 3 digits, it's just 2. So it would be the same as that just not as a hundred.

Raina runs 3 miles in 25 minutes. At the same rate, how many miles would she run in 20 minutes?
Answer:
2.4miles
Step-by-step explanation:
3/25 = x/20
60/25=x=2.4miles
Set up a ratio:
3/25 = x/20
Cross multiply:
3x 20 = 25x
60 = 25x
Divide both sides by 25
X = 2.4 miles

The difference between the annual and semi-annual compound interest on a sun of money is Rs. 482 at the rate of 20% per annum for 2 years. Find the sum.
The sum of money cannot be negative, it indicates an error in the calculation. However, the negative value of x suggests that the compound interest for the annual compounding is greater than the semi-annual compounding, which is not possible.
Let's find the sum of money using the given information.
First, we need to calculate the compound interest for both annual and semi-annual compounding.
For annual compounding:
Principal amount (P) = x (the sum of money)
Rate of interest (R) = 20% per annum = 0.2
Time (T) = 2 years
The compound interest for annual compounding is given by the formula:
CI = P * (1 + R)^T - P
CI_annual = x * (1 + 0.2)^2 - x
= x * 1.44 - x
= 0.44x
For semi-annual compounding:
Principal amount (P) = x (the sum of money)
Rate of interest (R) = 20% per annum = 0.2
Time (T) = 2 years
Number of compounding periods in a year (n) = 2 (semi-annual)
The compound interest for semi-annual compounding is given by the formula:
CI = P * (1 + R/n)^(n*T) - P
CI_semi-annual = x * (1 + 0.2/2)^(2*2) - x
= x * (1 + 0.1)^4 - x
= 1.4641x - x
= 0.4641x
The difference between the annual and semi-annual compound interest is given as Rs. 482.
CI_annual - CI_semi-annual = 0.44x - 0.4641x = 482
To solve for x, we can set up the equation:
0.44x - 0.4641x = 482
-0.0241x = 482
x = 482 / -0.0241
x ≈ -20000
Since the sum of money cannot be negative, it indicates an error in the calculation. However, the negative value of x suggests that the compound interest for the annual compounding is greater than the semi-annual compounding, which is not possible.

translate left 9 units, stretch by a factor of 5, and translate down 23 units
Answer:
j(x) = 5 |x+9|-23
Step-by-step explanation:
f(x) = |x|
translate left 9 units
y = f(x + C) C > 0 moves it left
g(x) = |x+9|
translate down 23 units
y = f(x) + C C < 0 moves it down
h(x)= |x+9|-23
stretch by a factor of 5
y = Cf(x) C > 1 stretches it in the y-direction
j(x) = 5 |x+9|-23

The volume of the crayon given it's dimensions is 4,647.9 mm³
The surface area of the crayon is 2,388.9 mm².
What is the volume and surface area of the crayon?Cylinder:
r = d/2
= 8.5 mm/2
= 4.25 mm
h = 80 mm
Cone
r = d/2
= 6.5 mm/2
= 3.25 mm
h = 10 mm
Volume of a cylinder = πr²h
= 3.14 × 4.25² × 80
= 3.14 × 18.0625 × 80
= 4,537.3 mm³
Volume of a cone = 1/3πr²h
= 1/3 × 3.14 × 3.25² × 10
= 1/3 × 3.14 × 10.5625 × 10
= 331.6625/3
= 110.5541666666666
Approximately,
110.6 mm³
Volume of the crayon = Volume of a cylinder + Volume of a cone
= 4,537.3 mm³ + 110.6 mm³
= 4,647.9 mm³
Surface area of a cone = πr (r + √h² + r²)
= 3.14 × 3.25(3.25 + √10² + 3.25²)
= 3.14 × 3.25(3.25 + √100 + 10.5625)
= 3.14 × 3.25 (3.25 + √110.5625)
= 3.14 × 3.25(3.25 + 10.5)
= 3.14 × 3.25(13.75)
= 3.14 × 44.6875
= 140.3 mm²
Surface area of a cylinder = 2πrh + 2πr²
= 2×3.14×4.25×80 + 2×3.14×4.25²
= 2,135.2 + 113.4325
= 2,248.6 mm²
Surface area of the crayon = Surface area of a cone + Surface area of a cylinder
= 140.3 mm² + 2,248.6 mm²
= 2,388.9 mm²
Hence, 2,388.9 mm² and 4,647.9 mm³ is the surface area and volume of the cone.

Which of the following is a result of shifting a circle with equation (x-3)2+ (y-5)2 = 36Which of the following is a result of shifting a circle with equation down 2 units
The equation of the shifted circle is (x-3)² + (y-3)² = 36.
Shifting a circle with equation (x-3)² + (y-5)² = 36 down 2 units means that we need to subtract 2 from the y-coordinate of the center of the circle. Since the center of the circle is (3, 5), the new center will be (3, 3) after the shift.
To find the equation of the shifted circle, we can simply replace the y-coordinate of the center with the shifted value in the original equation:
(x-3)² + (y-3)² = 36
This is the equation of a circle with center (3, 3) and radius 6, which is the result of shifting the original circle down 2 units.
