Answer:

4000 meters

Step-by-step explanation:

There are 60 minutes in an hour. Divide 60 by 14 and get 4. So she walks 4 km in an hour, but we want to know the answer in meters so we multiply 4 by 1000 to get 4000 meters.

Answer:

larger number=19

smaller number=7

Step-by-step explanation:

x=2y+5

x-y=12

(2y+5)-y=12

y+5=12

y=7

x=2(7)+5

x=14+5

x=19

Answer:

b=7,A=19

Step-by-step explanation:

A=2b+5

a-b=12

2) make both equations equal to 'a' by adding b on both sides so

a=2b+5,a=b+12

since both equations are equal to a, they are equal(is a=b then b=c property)

2b+5=b+12

this is a start, you can finish by combining the like terms and moving them to one side to get b=7 and a=19

The correct statement regarding whether we can determine the order of the rational numbers:

C) No, it is not possible to determine the order of the rational numbers because we do not know the signs of the rational numbers.

The absolute value of a number is the number without the signal, for example:

|-2| = |2| = 2.

In this problem, we are only given the absolute value of the numbers, we do not know the signs of the numbers, hence we cannot order them.

No, we cannot determine the order of the set of rational numbers because we only know their absolute values, not their signs. The answer is option C.

The question is asking whether we can determine the order of a set of rational numbers given their absolute values. The answer to this is option C: No, it is not possible to determine the order of the rational numbers because we do not know the signs of the rational numbers. Knowing only the absolute values does not give us any information about whether the original rational numbers were positive or negative. Absolute value only indicates the magnitude of a number, not its sign, therefore without this information, the original sequence of the rational numbers cannot be determined.

a. Equation that represents the volume of the rectangular prism glass is:  (x)(x - 8)(1) = 768

b. The dimensions are, length = 32 cm, width = 24 cm.

Volume = (l)(w)(h)

Given the following dimensions of the glass case:

a. Plug in the values into the volume formula to find the equation

(x)(x - 8)(1) = 768

x² - 8x - 768 = 0

b. Factorize x² - 8x - 768 = 0 to find the x, and find the dimensions of the rectangular prism glass

x² - 8x - 768 = 0

(x + 24)(x - 32) = 0

x= −24 or x = 32

The length cannot be a negative number, so:

Length of the glass = x = 32 cm

Width = x - 8 = 32 - 8 = 24 cm

Answer:

option D

0 < t < 3

Step-by-step explanation:

Given in the question the equation

d = 144 - 16t²

where d is the distance

           t is the time

Since, it is a descent, d should be decreasing until it reaches zero

by plugging d = 0 in the equation

0 = 144 - 16t²

-144 = -16t²

144/16 = t²

t² = 9

take square root on both sides

√t² = √9

t = ±3

since time can't be negative so we will reject -3

t = 3

This means that at 3 seconds the roller coaster was at ground but before that it was in the air

so when t < 3 Greg's car was moving in the air.

3+|n•-9|=4

|n•-9|=1

n•-9=1 Or n•-9= -1

n= -1/9 n=1/9

n=±1/9

Answer:

The value of x is ± (1/9).

Step-by-step explanation:

Consider the provided statement.

If 3 is added to the absolute value of the product of a number and −9,

Now convert this into mathematical form.

Let the number is x then the product of number and -9 is -9x.

For absolute value we use the mode. Thus the required expression is:

3 + |-9x|

Now it is given that the result is equal to 4. Thus,

3 + |-9x| = 4

Solve the above equation as shown:

|-9x| = 4-3

|-9x| = 1

Now remove the mode by introducing ± sign as shown:

-9x = ± 1

-9x = 1 or -9x = -1

x = -1/9 or x = 1/9

Hence, the value of x is ± (1/9).

Answer:

D. 30 2/3

Step-by-step explanation:

What you want to do is convert everything for feet, ill explain why later. 1 yard is 3 feet long. SO 9 x 3 = 27. 27 + 2 = 29 feet. The patio is 29 feet long.

5 x 3 = 15. 15 + 2 = 17 feet. So the patio is 29 x 17. To find the perimeter, you want to do: 29 + 29 + 17 + 17 = 92 feet. Convert it back to yards by doing 92/3. That equals 30.6667. In other words, 30 2/3. The answer is D. Hope this helps!

Answer:

Step-by-step explanation:

The problem is asking for the perimeter in yards, that means we have to transform feet to yards. Also, remember that the perimeter refers to the sum of all sides.

We know that 1 yard represent 3 feet. So:

[tex]2ft\frac{1yd}{3ft}=\frac{2}{3}yd[/tex]

That is, 2 feet represent 2/3 yards.

Now, we have to sum all sides:

[tex]2(9+\frac{2}{3})+2(5+\frac{2}{3})=18+\frac{4}{3}+10+ \frac{4}{3}=28+\frac{8}{3}=\frac{84+8}{3}=\frac{92}{3}=30\frac{2}{3}[/tex]

Therefore, the right answer is D.

Either $41.64 per person or $42.07, depending on if they tip pre or post sales tax.

Step-by-step explanation:

b=98.75

x=6.5/100=0.065

p=20/100=0.2

If tipping on taxed subtotal:

T=[(bx+b)p+(bx+b)]/3

T=[(98.75(0.065)+98.75)(0.2)+98.75(0.065)+98.75]/3

T=42.07 per person

If tipping on untaxed subtotal:

T=(bx+bp+b)/3

T=(98.75(0.065)+98.75(0.2)+98.75)/3

T=41.64 per person

It takes 10 workers 5 days to complete a road repair when working 2 hours a day.

So, this becomes : [tex]2*5*10=100[/tex] man hours required to finish the work.

Given is, if 2 people work for 5 hours a day, then let the number of days to finish the road be = d

So, total man hours = [tex]2*5*d=10d[/tex]

Now, [tex]10d=100[/tex] or [tex]d=10[/tex]

Hence, it will take 10 days for 2 people working 5 hours daily, to complete the work.

It will take 10 days for 2 people working 5 hours a day to finish the road repair.

From the question;

10 workers can finish road repair in 5 days working 2 hours a day

We need to find;

The number of days required to complete the road repair by 2 workers  working 5 hours a day.

Assuming the number of days required to complete the work is x

Number of working hours of 10 people is 10 hours ( 2 hours a day for 5 days)

Number of working hours of 2 people is 5x hours (5 hours a day for x days)

Note that; the number of workers or people is inversely related to the number of working hours.

Therefore;

Product of number of people and working hours or work done is a constant

Thus;

10 × 10 =  2 × 5x

100 = 10 x

x = 10

Therefore;

2 workers working 5 hours a day will require 10 days to complete the road repair.

Answer: 8 times

Step-by-step explanation:

By definition, the sum of the exterior angles of a polygon is 360 degrees.

Therefore, each exterior angle of the polygon is:

[tex]\frac{360\°}{n}[/tex]

Where n is the number of sides of the polygon.

 The lengths of the sides of  a regular octagon are equal and the measures of the internal angles are equal too.

The sum of the exterior angles of a polygon is 360 degrees and it has 8 sides, therefore, the measure of each exterior angle is:

[tex]=\frac{360\°}{8}=45\°[/tex]

You know that the regular octagon rotates 360° about its center.

Therefore, keeping all the above on mind, you have that the number of times (which you can call x) the image of the octagon coincide with the preimage during the rotation is:

[tex]x=\frac{360\°}{45\°}=8\ times[/tex]

U find the rate of change by using the equation:

Y^2-y^1

————-

X^2-x^1

You can use the formula to find the rate of change:

Rate of change = (y₂ - y₁) / (x₂ - x₁)

To find the rate of change using a graph, you need to determine the slope of the graphed line or curve at a specific point. The slope represents the rate at which the dependent variable changes with respect to the independent variable.

Here's a step-by-step process to find the rate of change using a graph:

a) Identify two points on the graph that you want to calculate the rate of change between.

These points should have known coordinates (x₁, y₁) and (x₂, y₂).

b) Calculate the difference in the dependent variable (y) between the two points: Δy = y₂ - y₁.

c) Calculate the difference in the independent variable (x) between the two points: Δx = x₂ - x₁.

d) Divide the difference in the dependent variable by the difference in the independent variable: Δy/Δx.

e) The result of this calculation represents the average rate of change between the two points. If you want to find the instantaneous rate of change at a specific point, you can make the interval between the two points infinitesimally small by moving the points closer together. In this case, the rate of change will be represented by the slope of the tangent line to the graph at that point.

By following these steps, you can determine the rate of change at a particular point on a graph.
