Could anyone help with math?? Will up vote, thanks!If a cone-shaped vase can hold 45 cubic centimeters of water and has a radius of 2 centimeters, what is the height of the vase? Use 3.14 for pi. Round your answer to the nearest hundredth.

7.45 centimeters
10.75 centimeters
14.33 centimeters
22.50 centimeters

Answers

Answer 1
Answer:

Answer:

The height of the cone is 10.75 cm.

Step-by-step explanation:

Given the volume of cone = 45 cubic cm

Radius of the cone = 2 cm

Height of the cone = ?

The volume formula of cone is = \pi r^(2) (h)/(3)

45= 3.14*2*2* (h)/(3)

=> 45*3 =12.56h

=> 135=12.56h

h = 10.748 ≈ 10.75 cm

So, the height of the cone is 10.75 cm.

Answer 2
Answer: volume of a cone  V = pi * r * r * h / 3
so V = 45, r = 2 therefore 45 = 3.14 * 2 * 2 * h /3  => 45 = 3.14 * 4 * h /3
=> 135 = 3.14 * 4 * h  => 33.75 = 3.14 * h  => 10.75 = h
height = 10.75 cm rounded to 2 decimal places

redo question 18 above with the same amount of deposit and the same interest rate, but with the interest compounded quarterly. how much money would you have at the end of the four years in this situation?

Answers

There are no given figures. I'll just show what the difference is. Let us assume the following
Principal = 10,000
interest rate = 12%
term = 4 years

Simple Interest = Principal * interest rate * term
S.I = 10,000 * 12% * 4 years
S.I = 4,800

Total value at the end of 4 yrs = 10,000 + 4,800 = 14,800

Compounded Interest. Compounded quarterly.
A = P(1 + r/n)^n*t
A = 10,000 (1 + 12%/4)^4*4
A = 10,000 (1.03)^16
A = 10,000 (1.60)
A = 16,000 value after 4 years.

Please help me solve all of these for M and B.1) Y=10/3x+19
2) Y=-2/7x+2

6) Y= 2/7x+2


Please and thank you!

In number 1:

m = 10/3

b = 19

Step-by-step explanation:

To find the answers to these, simply look to the coefficient of x and the constant at the end of the equation. The number attached to x is always m (which is known as the slope). The number at the end is b (or the y-intercept).

Find the Area of the figure below, composed of a rectangle and a semicircle. Round to the nearest tenths place.

Answers

Answer:

153.1 square unit

Step-by-step explanation:

for rectangle

length = 16

breadth = 8

area of rectangle = l*b

=16*8

=128 square unit

semicircle

diameter =8

area of semicircle =πd^2/8

=3.14 * 8^2 /8

=3.14 *64/8

=200.96/8

=25.12 square unit

area of the givem figure = area of rectangle + area of semicircle

=128 + 25.12

=153.12

=153.1 square unit

Final answer:

To find the area of the figure made up of a rectangle and a semicircle, calculate the areas of both shapes and add them together. Use the formula for the area of a rectangle, and calculate the area of the semicircle by finding half the area of a full circle with the same radius. Finally, sum up the areas to find the total area of the figure.

Explanation:

To find the area of the figure, we need to find the areas of the rectangle and the semicircle, and then add them together. The area of the rectangle is found by multiplying its length by its width. The area of the semicircle is half the area of a full circle with the same radius. Finally, we add the two areas together to get the total area of the figure.

Let's assume the length of the rectangle is 10 units and the width is 5 units. The area of the rectangle is then 10 units * 5 units = 50 units^2. If the radius of the semicircle is 3 units, the area of the semicircle is half the area of a full circle with radius 3 units, which is 1/2 * 3.14 * 3^2 = 14.13 units^2 (rounded to the nearest tenths place).

Therefore, the total area of the figure is 50 units^2 + 14.13 units^2 = 64.13 units^2 (rounded to the nearest tenths place).

Translate the sentence into an equation. The product of 8 and a number increased by 4 is 60.a. 8y + 4 = 60
b. 4y + 8 = 56
c. 8 ÷ y + 4 = 56
d. y + 8 + 4 = 56

Answers

Okay so if they say the product of 8 and a number that means multiplication. If they said the quotient of 8 and a number that would mean dividing. so knowing this your answer would be A because 8y means 8 times y which could be any number and then when you add 4 it has to equal 60. The answer is A.
Hope that helps.

Final answer:

The equation for the sentence is 8y + 4 = 60.

Explanation:

The sentence can be translated into the equation 8y + 4 = 60.

Here's why:

  1. The phrase 'the product of 8 and a number' can be represented as 8y, where y is the number.
  2. The phrase 'increased by 4' means adding 4 to the product.
  3. The phrase 'is 60' means the sum is equal to 60, which is represented by the equal sign (=) in the equation.

Therefore, the correct answer is a. 8y + 4 = 60.
