Answer:  speed = 17m/s

              time taken = 3min = 3 x 60 = 180 seconds   (1min = 60sec)

distance = ST

               = speed x time

                = 17 x 180

= 3060m

Answer:

NQ=15

Step-by-step explanation:

To solve this we can use the side-splitter theorem.

NS/SR=NP/PQ

PQ=x since we do not know it's value

now to subsitute the given/known values.

12/78=2/x

solve for x using cross multiplication.

12x=156

x=13

PQ=13

NQ= PQ+NP

NP=2

NQ=13+2

NQ=15

The length of NQ is 15.

Answer:  3x-2y=24 in slope intercept form is [tex]y=\frac{2}{3}x -12[/tex]

The graph of the equation is in the attachment

Step-by-step explanation: Slope intercept form is y = mx + b

m is the slope b is the y-intercept  x is the "input" in the equation y is the "output" or the y-value in the graph for a given x-value.

You need to rearrange the standard form to slope-intercept to isolate y on the left side of the equation.

3x - 2y = 24 Standard form. Subtract 3x from both sides.

-2y = -3x + 24   divide both sides by -2

-2y/-2 = -3x/-2 + 24/-2 . Simplify.

y = 3x/2 - 12 .

To clarify the slope as a fraction

[tex]y=\frac{2}{3}x -12[/tex]

Answer:

He needs 3 packs of hot dogs and 2 packs of hot dog buns. He has 4 hot dogs and 4 hot dog buns left over.

Step-by-step explanation:

Because 8 x 3 = 24 and 12 x 2 = 24

But since he needs enough for 20 people he would have 4 hot dogs and 4 hot dog buns leftover.

16 cups in 1 gallon

16*6 = 96 cups in 6 gallons

96 - 30 = 66

Answer:

3 bags per weekday

Step-by-step explanation:

Total bags of leaves at the end of the week = 26 bags

Bags of leaves she fills over the weekend = 11 bags

Bags of leaves she fills during weekdays = x bags

Total bags of leaves at the end of the week = Bags of leaves she fills over the weekend + Bags of leaves she fills during weekdays

26 = 11 + x

Subtract 11 from both sides

26 - 11 = 11 - 11 + x

15 = x

x = 15 bags

If she fills the same number of bags with leaves on each of the 5 weekdays.

how many bags she filled each weekday.

Bags she filled each weekday = Total Bags of leaves she fills during weekdays / 5 weekdays

= 15 bags / 5 weekdays

= 3 bags per weekday

Answer:

3

Step-by-step explanation:

1. Bags filled on weekdays + bags filled on weekends = total bags filled

2. 5b + 11 = 26

3. Isolate variable (subtract 11 from both sides) = 5b=15

4. Divide both sides by 5 = 15/5 = 3

5. How many bags does Grace fill each weekday? = 3

Answer:

[tex]y = 50x[/tex]

Step-by-step explanation:

Let's start off by trying to find the slope/gradient (commonly denoted as [tex]m[/tex]) of this function

[tex]m = \frac{\Delta y}{\Delta x}[/tex]

This means we divide the change in y over the change in x

Let's pick, for example, x = 3 (who's corresponding y is 150) and x = 4 (who's corresponding y is 200)

[tex]m = \frac{200 - 150}{4 - 3}\\\\m = 50[/tex]

Now we have this:

[tex]y = 50x+b[/tex]

Let's plug in a random value of x and y from this function in order to find b. I'll pick x = 2:

[tex]100 = 50\cdot 2 + b\\100 = 100 + b\\b = 0[/tex]

Since b is 0, we don't have to write it on our equation, meaning that our final equation is just

[tex]y = 50x[/tex]

To verify this, let's say we didn't know the value of y when x is equal to 4 and all we had was that equation:

[tex]y = 50\cdot 4\\y = 200[/tex]

Just like it is on the graph :)

Good luck!

Answer:

Step-by-step explanation:

Using the information provided we can create two different equations for this system. The first of which would be Fred's overall weight, while the second equation would be Fred's and Barney's combined weight. These equations would be the following...

F = 2B - 40

320 = F + B

As requested I will not solve the system of equations and leave them as they are.

Answer:

87

Step-by-step explanation:

Let d = number of desktops.

Let a = number of laptops.

a + d = 165

a = d + 9

d = a - 9

a + d = 165

a + a - 9 = 165

2a - 9 = 165

2a = 174

a = 87

Answer: 87

Answer:

87

Step-by-step explanation:

By the remainder theorem,

p(a) = 3a³ + a² + 5a = -7

so that

3a³ + a² + 5a + 7 = 0

Since you know a is an integer, you can try to factorize this, or use the rational root theorem to generate a list of potential rational roots, and from there you'd select the integer roots. The rational ones are of the form m/n, where m divides the constant term 7 and n divides the leading coefficient 3. They are

a = ± 1 or ± 1/3 or ± 7 or ±7/3

so there are 4 integer candidates,

a = -1 or 1 or -7 or 7

Check the value of f(a) = 3a³ + a² + 5a + 7 at each of these:

a = -1   →   f(a) = 0

a = 1   →   f(a) = 16

a = -7   →   f(a) = -1008

a = 7   →   f(a) = 1120

and only a = -1 is a root of 3a³ + a² + 5a + 7, so that's your answer. In fact,

3a³ + a² + 5a + 7 = (a + 1) (3a² - 2a + 7)

Answer:

the number of milligrams of the vitamin in the drink is 75 mg

Step-by-step explanation:

The computation of the number of milligrams of the vitamin in the drink is as follows:

= RDA of the vitamin × given percentage ÷ percentage

= 50 mg × 150 ÷ 100

= 75 mg

hence, the number of milligrams of the vitamin in the drink is 75 mg

We simply applied the above formula so that the correct value could come

Answer:

0.556 foot wide or 6 ²/₃ inches wide

Step-by-step explanation:

first we must calculate the total perimeter of the poster that will be decorated with the fabric:

the total perimeter of the poster = 4 + 4 + 5 + 5 = 18 feet long

you have 10 square feet of fabric, so its width should be 10 / 18 = 0.556 foot wide or 6 ²/₃ inches wide

Answer:

C

Step-by-step explanation:

By converting radians 5π /6 into a degree, we get the nearest degree 150.

We can convert radians into a degree by using the formula

Degree = Radians x (180°) / π

To 5π /6 convert radians into a degree,

Degree = Radians x (180°) / π

Degree =  5π /6 x (180°) / π

             = 5 /6 x  (180°)

             = 150°
