If the diameter is 26 inches, what is the radius

Answers

Answer:

13 inches

Step-by-step explanation:

In any circle, the radius is always half of the diameter.

So, the diameter can be found by multiplying the radius by 2, and the radius can be found by dividing the diameter by 2.

Since the diameter is 26 inches, we can divide this by 2 to get the radius

26/2

= 13

The radius is 13 inches

Answer:

[tex] \bf \huge13[/tex]

Step-by-step explanation:

Given that :

the diameter is 26 inches.

to find :

what is radius .

formulas used :

radius = diameter / 2

explanation :

we know that,

finding the radius

diameter = 26 inches

⟼ radius = diameter / 2

⟼ radius = 26 / 2 inches

⟼ radius = 13 / 1 inches

⟼ radius = 13 inches.

radius is 13 inches .

sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{2.5}{5}[/tex] = [tex]\frac{1}{2}[/tex] , then

x = [tex]sin^{-1}[/tex] ([tex]\frac{1}{2}[/tex] ) = 30

Nic sells advertising packages for a radio station. The company pays him $ 150 $150 per week and they also pay him $ 75 $75 for every package he sells. His friend Asia works for the same radio station but she receives a salary only, which is $ 1 , 275 $1,275 per week. How many packages does Nic need to sell in a week to earn as much as Asia?

Answers

Answer:

15 Packages

Step-by-step explanation:

Let number of packages = x

For Nic

Nic sells advertising packages for a radio station. The company pays him $ 150 per week and they also pay him $ 75 for every package he sells.

Equation =

150 + 75x

His friend Asia works for the same radio station but she receives a salary only, which is $ 1 , 275per week.

We solve by equating

150 + 75x = 1275

75x = 1275 - 150

75x = 1125

x = 1125/75

x = 15 Packages

Answer:

Step-by-step explanation:

Slope of line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the graph attached,

Slope of the line passing through (-3, 0) and (0, 5) = [tex]\frac{5-0}{-3-0}[/tex]

                                                                                    = [tex]-\frac{5}{3}[/tex]

Line passing through a point (h, k) and slope 'm' will be,

y - h = m(x - k)

Since, line passing through (11, 0) is parallel to the line given in the graph,

Slope of the parallel line will be same as [tex]-\frac{5}{3}[/tex]

Equation of a line passing through (11, 0) and slope = [tex]-\frac{5}{3}[/tex]

y - 0 = [tex]-\frac{5}{3}(x-11)[/tex]

y = [tex]-\frac{5}{3}(x-11)[/tex]

Now satisfy this equation with the points given in the options,

Option (1)

For (1.67, -15.59),

-15.59 = [tex]-\frac{5}{3}(1.67-11)[/tex]

-15.59 = -15.55

False.

Therefore, given point doesn't lie on the line.

Option (2)

For (-0.33, -13.59)

-13.59 = [tex]-\frac{5}{3}(-0.33-11)[/tex]

-13.59 = -18.88

False

Option (3)

For (0.67, -18.59),

-18.59 = [tex]-\frac{5}{3}(0.67-11)[/tex]

-18.59 = 17.22

False

Option (4)

For (1.67, -15.59)

-15.59 = [tex]-\frac{5}{3}(1.67-11)[/tex]

-15.59 = -15.55

False.

Therefore, none of the points given in the options are lying on the line.

Sin A = 5/13; tan C = 12/5

Step-by-step explanation:

Sin = opposite / hypotenuse. The opposite of A is 5, and the hypotenuse is 13, therefore Sin A = 5/13.

Tan = opposite / adjacent. The opposite of C is 12, and the adjacent is 5, so tan C = 12 / 5

A cylindrical barrel holds 10,164 cubic inches of oil (44 gallons). If the cylindrical barrel is 23 inches in diameter, what is the approximate height of the barrel?
a. 21 inches
b. 24 inches
c. 60 inches
d.141 inches

Answers

Answer:

I believe it’s A.21

Step-by-step explanation:

HOPE THIS HELPS YOU

The approximate height of the barrel is 22.9 inches. They are also important in mathematics and engineering, as they are used to model and solve problems in various fields, such as calculus, geometry, physics, and fluid mechanics.

What is Cylinder?

A cylinder is a three-dimensional geometric shape that consists of two parallel, congruent circular bases connected by a curved surface. The curved surface is composed of a set of parallel lines that connect the two circular bases.

here, we have,

The cylinder can be described by several measurements, including its height (the distance between the two circular bases), its radius (the distance from the center of one circular base to its edge), and its diameter (the distance across the cylinder at its widest point, passing through the center of the circular bases).

We can use the formula for the volume of a cylinder to find the height of the barrel:

V = πr²h

We are given that the volume of the oil is 10,164 cubic inches and the diameter (which is twice the radius) is 23 inches.

r = 23/2 = 11.5 inches

10,164 = π(11.5)²h

Solving for h, we get:

h = 10,164 / (π(11.5)²) ≈ 22.9 inches

So the approximate height of the barrel is 22.9 inches.

Water makes up about 60% of the average adult's body weight. Represent this percent by shading in the squares.

Answers

Answer:

shading three boxes

Step-by-step explanation:

It is given that :

The body weight of an average adult = 60%

We have to show this by shading the square boxes shown.

There are 5 square boxes in total which makes up 100%.

So divide 100 by 5, we can 20% for each box.

So, 20% + 20% + 20%  will give us 60%

Therefore, shading three boxes will give us 60% which is the water percent in an average adult's body weight.

This is represented by the figure below.
