Answer:

A

Step-by-step explanation:

He paid $376.20

The cost to rent a canoe for 4 hours is $57.

It should be noted that the equation given is illustrated as equation C= 8h+25 represents the cost in dollars, C, to rent a canoe.

C = 8h + 25.

where h = number of hours

C = 8h + 25

When h = 4..

C = 8h + 25

C = 8(4) + 25

C = 32 + 25

C = 57

Therefore, the cost to rent a canoe for 4 hours is $57.

Answer:

6 people

Step-by-step explanation:

To figure this out, let's set up an equation.

We know 30 people went last year to Universal, and that this is 5 times as many people as who went the year before

So to figure out how many went the year before, we divide 30 by 5

30/5 = 6

So 6 people went to Universal the year before.

Han produced hot chocolate by combining 6 tablespoons of cocoa with 4 cups of milk. For every spoonful of cocoa, 0.67 glasses of milk are required.

The relationship between two values is described by a ratio. It displays how frequently one value appears in another. The answer to this question will depend on how many cups of milk there are to every tablespoon of chocolate.

Divide the provided cups of coffee by the cost of the tablespoon of coffee to get the required quantity of milk per tablespoon of chocolate.

Cups per tablespoon of coffee equal cups of milk divided by tablespoons of cocoa.

Given that,

Number of cups of milk = 4

Tablespoons of cocoa = 6

4/6=0.67 cups

Therefore, for every spoonful of cocoa, 0.67 glasses of milk are required.

Answer:

Step-by-step explanation:

Given two points on the linear toll function T(d) are (20, 119) and (33, 184), you want the equation for the function T(d), and the value of T(96).

It is usually convenient to write the equation of a line in slope-intercept form when you want to find the value at a particular point. To use that form, we need to know the slope of the line. It is given by the formula ...

  m = (y2 -y1)/(x2 -x1)

Using the given points, we have ...

  m = (184 -119)/(33 -20) = 65/13 = 5

The point-slope form of the equation for a line is ...

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

Using the first point and the slope we found, the equation is ...

  y -119 = 5(x -20)

Solving the above equation for y, we get ...

  y = 5x -100 +119 . . . . . . . simplify, add 119

  y = 5x +19 . . . . . . . . . . combine terms

Using variables d and T instead of x and y, the function is ...

  T(d) = 5d +19

The value T(96) is ...

  T(96) = 5(96) +19 = 480 +19 = 499

The toll for 96 miles is 499 cents.

6 inches more than 2 times the height, 54 square inches the base and height is

b=13.8 inches

h=3.9 inches

Let base and height be b and h respectively,

So ,

Area = b*h= 54 square inches

So,

(2h+6)(h)=54

2h²+6h=54

h²+3h=27

h²+3h-27=0

The measurement that indicates the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the border of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

The quantity of unit squares necessary to completely cover a shape is its area. As a result, it is stated and measured in square units.

Area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies. Consider your square as being composed of smaller unit squares.

Answer:

3.9 x [tex]10^{8}[/tex]

Step-by-step explanation:

0.39 is not in scientific notation.  For a number to be in scientific notation the first factor has to be 1 or greater, but less then 10.  0.39 is less than one.

First we must write 0.39 in scientific notation.  We need to move the decimal so that the number is greater than 1, but less than ten.  If we move the decimal one place to the right, we get 3.9.  The standard number is smaller than 3.9.  How much smaller?  [tex]10^{-1}[/tex] smaller.

0.39 in scientific notation would be 3.9 x [tex]10^{-1}[/tex].  We cannot forget the [tex]10^{9}[/tex], so our number looks like this now:

3.9 x [tex]10^{-1}[/tex] x [tex]10^{9}[/tex]  The product of powers principle tells us that if we have powers with the same bases, we can add the exponents.

With the help of the volume of cube it is concluded that Beth should buy 4 bags of beans.

The volume of a cube is the total three-dimensional space that it occupy. A cube's volume is expressed as cubic units. The SI unit of volume is the cubic meter [tex](m^3)[/tex], which is the volume occupied by a cube with each side measuring 1 m.

The first thing to do in this case is to find the volume of the cube, which will be given by:

V = [tex]L ^ 3[/tex]

where, L = sides of the cube.

Substituting we have:

V = [tex](2) ^ 3[/tex]

V = [tex](8) ^ 3[/tex]

Since, beans are sold in bags that hold two cubic feet of beans.

The slope of Parallel Lines:

Slopes of parallel lines are equal. The parallel lines are equally inclined with the positive x-axis and hence the slope of parallel lines is equal. If the slopes of two parallel lines are represented as m1, m2 then we have

In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.

The net change in the y-coordinate is represented by Δy and the net change in the x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,

m = change in y/change in x = Δy/Δx

Where “m” is the slope of a line.

The slope of the line can also be represented by

tan θ = Δy/Δx

So, tan θ to be the slope of a line.

Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter ‘m’

m1 = m2.

y 2/3 = x + 1 ...1

2y = 3x+3

y = 3/2x +3/2

m1= 3/2

x,y = -6,-1

y = mx +b

(y-y1 ) =m (x-x1) +b

m1=m2

m2= 3/2

(y +1) = 3/2 (x+6)

2(y+1 )= 3x+18

the equation of the line that is parallel to y 2/3 = x + 1 and passes through the point (–6, –1) = 2y+2 = 3x+18

a. The weight of a particular crate such that the probability of randomly selecting a heavier crate is 0.05 is 16.30kg.

b. The probability that a randomly selected crate will weigh more than 16kg is 0.0764.

c. The probability that.at least 2 of them will weigh more than 16kg is 0.4584.

a. From the information, there is a mean of 14 kg and a standard deviation of 1.4 kg. The weight will be:

Let the weight = x

X = (Z × mean × standard deviation)
