The speed of the boat is 7 miles/hour and the current of the river is 1 mile/hour.

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

We have:

A boat goes 24 miles at a constant speed in 4 hours against a river current.

It takes the boat 3 hours to go the same distance at the same speed with the current of the river.

Let's suppose the speed of the boat is x miles/hour and the current of the river is y

x- y = 24/4

x - y = 6 ..(1)

x + y = 24/3

x + y = 8  ..(2)

Adding equation (1) and (2):

2x = 14

x = 7 miles/hour

y = 8 - 7 = 1 miles/hour

Thus, the speed of the boat is 7 miles/hour and the current of the river is 1 mile/hour.

Step-by-step explanation:

8.3÷0.25

Multiply that by 30 and you get 996

The actual distance between the two cities will be 996 miles.

Distance is defined as the product of speed and time.

Scale is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions of the actual figure or object.

The given scale is 0.25 inches on the map representing 30 miles.

If the distance between two cities is 8.3 inches

As per the given scale, the actual distance between the two cities will be as:

⇒ 8.3 × 30/0.25

⇒ 83/10 × 3000/25

⇒ 249,000/250

Apply the division operation, and we get

⇒ 996 miles

Given:

One linear function represented by the table.

Another linear function represented by the graph.

To find:

The greater unit rate and greater y-intercept.

Solution:

Formula for slope (unit rate):

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

From the given table it is clear that the linear function passes through (0,5) and (5,15). The function intersect the y-axis at (0,15), so the y-intercept is 15.

[tex]m_1=\dfrac{15-5}{5-0}[/tex]

[tex]m_1=\dfrac{10}{5}[/tex]

[tex]m_1=2[/tex]

So, the unit rate of first function is 2.

From the given graph it is clear that the linear function passes through (0,6) and (-4,0). The function intersect the y-axis at (0,6), so the y-intercept is 6.

[tex]m_2=\dfrac{0-6}{-4-0}[/tex]

[tex]m_2=\dfrac{-6}{-4}[/tex]

[tex]m_2=\dfrac{3}{2}[/tex]

So, the unit rate of first function is [tex]\dfrac{3}{2}[/tex].

Now,

[tex]2>\dfrac{3}{2}[/tex]

[tex]m_1>m_2[/tex]

And,

[tex]15>6[/tex]

Therefore, the greater unit rate of the two functions is 2. The greater y-intercept of the two functions is 15.

Answer:

The greater unit rate of the two functions is 2.

The greater y-intercept of the two functions is 6.

Step-by-step explanation:

Answer:

Step-by-step explanation:

to find x we can use tangent function

tan 31= x/9

0.60=x/9

x=0.60*9=5.4 choice B

The measure of x side.

We have given a right angle triangle whose angle A=31 degrees and two sides that is x and 9.

We have to determine the value of x.

Therefore we use here the trigonometric ratio

[tex]tan\theta=\frac{opposite side}{adjacent side}[/tex]

Therefore we get

tan 31= x/9

tan(31)=0.60

0.60=x/9

Isolate the x

x=0.60*9

x=5.4

Therefore option B is correct.

Answer:

The numerical value of the circumference is greater than the numerical value of the area.

Step-by-step explanation:

This has already been answered

The numerical value of the circumference is less than the numerical value of the area.

For a circle of radius R, remember that the diameter is twice the radius, we have:

area = pi*R^2

And the circumference is:

C = 2*pi*R

In this case, we have:

D = 6m

R = 6m/2 = 3m

The circumference is:

C = 2*3.14*3m = 18.84m

And the area:

A = 3.14*(3m)² = 28.26 m^2

So the area is larger than the perimeter, the true statement is:

"The numerical value of the circumference is less than the numerical value of the area."

Answer:

(2)(9) + 75 = 75+18

Step-by-step explanation:

(2)(9) + 75 = 75+18

The expression written as a product of a number and another sum is 3(25 + 8)

Given the expression 75 + 18, we are to write as a product of a number and another sum.

First we need to find the GCF of 75 and 18

75 = 3 * 25

18 = 3 * 6

Since 3 is common to both D+GCF, we can factor it out from the expression to have:

75 + 18 = 3(25 + 8)

Hence the expression written as a product of a number and another sum is 3(25 + 8)
