Answer:

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

0.81

Step-by-step explanation:

the answer is 0.81

0.9×0.9=0.81

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.

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.

Answer: The y intercept is 1.

Step-by-step explanation: Sorry I could only answer the one about the y-intercept. So basically finding the y intercept is where the line crosses at the y-axis. So in this case the y-intercept is 1 because thats the point the line crosses at the y-axis. I hope this clarifies your question and I hope this helps. Good Luck on your upcoming test if you have one soon!

Answer:

7inches

Step-by-step explanation:

Given the conversion rate expressed as:

1 in = 7ft

We are to find the equivalent with of  49ft in inches.

x in = 49ft

Divide both equations:

1/x = 7/49

Cross multiply;

7*x = 1*49

7x = 49

x = 49/7

x = 7

Hence the correct answer is 7inches

​

Answer:

7 inches

Step-by-step explanation:

(divide 49 by 7) 7 feet go into 49 feet 7 times. If there are 7 groups of 7 feet, and every 7 feet is one inch, then 7 inches is the width of the drawing.

Answer:

the answer is:

4 - 4x+ 2x = -3x -3

4 - 2x = -3x -3

4 + 3 = -3x +2x

7 = -x

x = (-7)

Answer: -7

Step-by-step explanation:

4(1 – x) + 2 x = –3( x + 1)

Simplify the parentheses

4 - 4x + 2x = -3x - 3

Combine like terms

4 - 2x = -3x - 3

Subtract like terms on each side of the equal sign to isolate variable

x=-7

Steps:

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)
