Answer 1

Answer:

52 in^2

Step-by-step explanation:

If the diameter = 3 in, then the radius = 1.5 in.

To find the surface area, you need to find the area of the two circle areas (the base and the top of the cylinder) and the "sides" of the cylinder. If you look at the net shape of a cylinder, look at the picture below. That middle region aka the "side" of the cylinder is actually a rectangle. The length of the rectangle is also the circumference of the circle and the width is also the height of the can.

So:

2 * Area of the circle + rectangle = total surface area of the can

= 2(πr^2) + 2πrh

= 2π(1.5^2) + 2π(1.5)(4)

= 2π(2.25) + 12π

= 4.5π + 12π

= 16.5π

≈ 51.8

≈ 52 in^2

Answers

Considering that it has only positive probabilities, and the sum of the probabilities is of 1, the table that shows a probability distribution is given by:

X 0 1 2 3

P 0.1 0.5 0.3 0.1

When does a table represent a probability distribution?

A table is formed by a set of points (x, P(x)), and represents a probability distribution if:

The sum of the probabilities is of 1.All probabilities are 0 or positive.

In this problem:

In the first table, there is a negative probability, which is P(X = 0) = -0.3.In the second and the fourth tables, the sums are of 1.2 and 0.8, respectively.

Hence, the table that represents a probability distribution is given as follows:

X 0 1 2 3

P 0.1 0.5 0.3 0.1

Which of the following is a property of all squares?
A.
There is only 1 pair of parallel sides.
B.
All 4 sides are congruent.
C.
There are 4 acute angles.
D.
Consecutive angles are complementary.

Answers

Answer:D.All sides are congruent

The solution is: a) Opposite sides are parallel, the following is true for all parallelograms.

What is parallelogram?

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

Here, we have

a) In a parallelogram, opposite sides are parallel (which is why it is called a Parallelogram).

b) Opposite angles are congruent (not ALL angles). The only parallelograms where all of the angles are congruent are Squares and Rectangles.

c) Consecutive angles are supplementary so their SUM must be 180°. Therefore if one angle is less than 90° (acute), the other angle must be greater than 90° so it is not possible that all angles are acute (∠ 90°).

d) The sides do not have to be equal. The only parallelogram whose sides have equal lengths are Squares.

Hence, The solution is: a) Opposite sides are parallel, the following is true for all parallelograms.

A tabletop in the shape of a trapezoid has an area of 5029 square cenimeters. Its longer base measures 123 cenimeters, and the shorter base is 65 cenimeters. What is the height?

Answers

Answer:

Length of height = 53.5 cm

Step-by-step explanation:

Given:

Area of trapezoid = 5,029 cm²

Length of longer base = 123 cm

Length of shorter base = 65 cm

Find:

Length of height

Computation:

Area of trapezoid = [(a+b)/2]h

5,029 = [(123 + 65)/2]h

5,029 = [(188)/2]h

5,029 = [94]h

Length of height = 53.5 cm

Answers

Answer: 36.9

Step-by-step explanation:

For this question you have to find out whether you are using Sin, Cos or Tan.

To work out which one you are using you can use SOH CAH TOA to help you.

SOH- The 'S' is for Sin, the 'O' and the 'H' is for Opposite over Hypotenuse.

CAH- The 'C' is for Cos and the 'A' and the 'H' is for Adjacent over Hypotenuse.

TOA- The 'T' is for Tan, the 'O' and the 'A is for Opposite over Adjacent.

As you have the Opposite (the side opposite the angle we're looking for) and the Adjacent (the side next to the angle were looking for) we would be using Tan.

So first you would have to write:

Tanθ=3/4

Then because we want Theta (θ) on it's own we would have to do the inverse to 'undo' the equation. Tan-1 is the inverse of Tan.

θ=Tan-1 3/4

To find the answer you would have to put it in your calculator.

θ=36.9

Answers

Answer:

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse

a^2 + (2.1)^2 = (2.9)^2

a^2 +4.41=8.41

a^2 = 8.41-4.41

a^2 =4

Take the square root of each side

sqrt(a^2)=sqrt(4)

a=2

a) 3 1/8
b) 1/8
c) 8
d) 8/25

Answers

Answer:

b) 1/8

Step-by-step explanation:

5/8 ÷ 5 = 1/8

The unit rate in cups per teaspoon is 1/8 cup of sugar.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

5/8 cup of sugar=5 teaspoons of vanilla.

or, 5 teaspoons of vanilla = 5/8 cup of sugar

So, 1 teaspoon of vanilla = (5/8)/5 cup of sugar

(5/8)/5 = (5/8)*(1/5)

(5/8)/5 =1/8

So, 1 teaspoon of vanilla = 1/8 cup of sugar

Hence, the unit rate in cups per teaspoon is 1/8 cup of sugar.
