Step-by-step explanation:

72 times 108 = 7776 sq inches

to convert inches to yds divide by 36

7776/ 36 = 216 sq yds

Answer: 6 yards^2

Step-by-step explanation:

first lets find the area of the space in inches and then convert the total to square yards :)

area = length * width

A = 108 * 72 = 7776 inches^2

now lets convert it

there are 1296 inches in a yard, so we divide 7776 by 1296 to find the number of square yards

7776 / 1296 = 6

so the area of the space is 6 yards^2

Answer:

57

Step-by-step explanation:

Answer:

x < 2

Step-by-step explanation:

Let's actually solve the given inequality 3x + 1 < 7.  First we want to combine the constants into one:  3x < 6.  Solving for x, we get x < 2.

The graph you have chosen as your answer is correct.  x does not equal 2, but rather is less than 2, as the given inequality states.  Since x is less than 2, we start at the (open) circle at 2 and move to the left.

Answer:

the range is 21.( range=highest value-lowest value)

Answer:

33

Step-by-step explanation:

180 minus 114 minus 33

soln,

x°+114°+33°=180° ( because sum of all angles of triangles is equal to 180°)

or, x°+147=180°

or, x°=180°-147°

hence, x°= 33°

Answer:

A) r=d/t

B) 221,760 feet per hour

C) 42 miles per hour

D) in this scenario feet per mile makes more sense since the distance is listed in feet.

Step-by-step explanation:

A) you solve for r by divided both sides of the equation by (t)time

B) you take your formula r=d/t and substitute the values of (d) and (t) with 665,280 feet and 3 hours.

C) convert feet to miles by dividing the given amount of feet by 5280 since there are 5,280 feet in 1 mile

D) use feet to make the calculations easier and to avoid making a mistake in converting feet to miles

Answer:

Step-by-step explanation:

This is exponential. I'll show you how I found it. After many attempts at other types of functions, I realized the points were either forming a quadratic or an exponential. Definitely not a line.

the standard form of an exponential function is

[tex]y=a(b)^x[/tex] so we sub in coordinates from the table to determine what the equation is and then test it on another set of points to see if it works. Using the first coordinate of (1, 2):

[tex]2=a(b)^1[/tex] so

[tex]a=\frac{2}{b}[/tex] . The next  coordinate is (2, 4), so:

[tex]4=\frac{2}{b}(b)^2[/tex] which simplifies down to

4 = 2b so

b = 2. Now we plug in 2 for b and solve for a:

a = 2/2 which is 1. So the equation, if this is exponential, is

[tex]y=1(2)^x[/tex] Let's test the next point in line and see if it works, (3, 8):

[tex]8?=?1(2)^3[/tex] and yes, 8 is equal to 2 cubed. And the next point says that 16 should equal 2 to the 4th, and it does, as well. So this is exponential...growth to be specific.

Answer:yes, base = 9. No, the exponent is not variable. yes, base =9/10.

Step-by-step explanation:

Given data

Radius= 14in

The expression for the area of circle is given as

A= πr^2

Area= 3.142*14^2

Area= 3.142*196

Area= 615.832in^3

Hence the area is 615.8in^3

Answer:

5/2

Step-by-step explanation:

We know,

Equation of the slope is, y = mx + c.   Where m is the slope.

y - 4 = 5/2*(x-2)

y = 5/2*(x-2) + 4

y = (5/2)x - 5 + 4

y = (5/2)x - 1

y = (5/2)x + (-1)      [y = mx + c form]

Slope, m = 5/2

Answer:

A

Step-by-step explanation:

The tangent- tangent angle DEF is half the difference of the measure of the intercepted arcs , that is

[tex]\frac{1}{2}[/tex] (y - 127) = 53 → A

The intercepted arcs of y is 1/2(y -127) = 53.

The intercepted arc exists the arc that exists inside the inscribed angle and whose endpoints exist on the angle. The vertex of an inscribed angle can be anywhere on the circle as stretched as its sides intersect the circle to construct an intercepted arc.

Let, DE and EF exist as tangents to O.

The value of y will be evaluated as follows:

For angle created outside of circle by intersection:

Two tangents or two secants or a tangent and a secant, the formula for angle created outside will be:

An angle formed outside = 1/2(Difference of Intercepted Arcs)

An angle formed outside exists ∠DEF = 53°

Intercepted arcs exist y and 127°

Hence, 53 = 1/2(y -127)

Therefore, the correct answer is option C). 1/2(y -127) = 53.

hope this helps

Answer:

Third option or 3,9,27,81

Step-by-step explanation:

A geometric sequence is a sequence where the term multiplies by the last term to make the next term.

In these options, we can clearly see the second and fourth one are not geometric as their relationship is not by multiplying.

The first option is also wrong since 4*-16 is -64, not 64.

That leaves the third option. 3*9 = 27, 9*27 is 81. Therefore, it is the third option

Answer:

  y = -1/2x +4

Step-by-step explanation:

The y-intercept is where the line crosses the y-axis, at y=4.

The slope is found by following the line to the right until it meets another grid line crossing point. That is 2 units to the right and down 1 unit.

The slope is ...

  m = "rise"/"run" = -1/2

Then the slope-intercept equation is ...

  y = mx + b . . . . . slope m, y-intercept b

According to the given information, the slope of the line is -1.

In mathematics, slope is a measure of how steep a line is, or how much y (vertical) changes for a given x (horizontal) change. It is represented by the letter "m" and is calculated as the change in y divided by the change in x, or rise over run. The slope can be positive, negative, zero, or undefined.

The answer is D, -1; the amount of water decreases by 1 gallon per minute.

To find the slope of the line, we need to use the slope formula:

slope = (change in y)/(change in x)

In this case, the change in y represents the change in the amount of water, and the change in x represents the change in time.

Option A says that the slope is 2/3, which means that for every 3 minutes, the amount of water decreases by 2 gallons. This is incorrect because as time increases, the amount of water should decrease, so the slope should be negative.

Option B says that the slope is -2/3, which means that for every 3 minutes, the amount of water decreases by 2 gallons. This is the same as option A but with a negative slope, which is correct because the amount of water decreases over time.

Option C says that the slope is -3/2, which means that for every 2 minutes, the amount of water decreases by 3 gallons. This is incorrect because the amount of water should decrease by the same amount every minute.

Option D says that the slope is -1, which means that for every minute, the amount of water decreases by 1 gallon. This is the correct answer because it describes a constant rate of change in the amount of water over time.

Therefore, according to the given information, the slope of the line is -1.

Answer:

The speed of the normal train is 60 kilometers per hour.

Step-by-step explanation:

Let suppose that both trains move at constant speed and cover the same distance. Then, we have the following identity:

[tex]v_{1}\cdot t_{1} = v_{2}\cdot t_{2}[/tex] (1)

Where:

[tex]v_{1}, v_{2}[/tex] - Average speeds of the express train and the normal train, in kilometers per hour.

[tex]t_{1}, t_{2}[/tex] - Travel times of the express train and the normal train, in hours.

In addition, there is the following relationship between average speeds:

[tex]v_{1} = v_{2} + 90[/tex] (2)

By (2) in (1), we have the following expression for the average speed of the normal train:

[tex](v_{2} + 90) \cdot t_{1} = v_{2}\cdot t_{2}[/tex]

[tex]90\cdot t_{1} = v_{2} \cdot (t_{2} - t_{1})[/tex]

[tex]v_{2} = \frac{90\cdot t_{1}}{t_{2}-t_{1}}[/tex]

If we know that [tex]t_{1} = 4\,h[/tex] and [tex]t_{2} = 10\,h[/tex], then the average speed of the normal train is:

[tex]v_{2} = 90\cdot \left(\frac{4\,h}{10\,h - 4\,h} \right)[/tex]

[tex]v_{2} = 60\,\frac{km}{h}[/tex]

The speed of the normal train is 60 kilometers per hour.
