Answer:

$38.1

Step-by-step explanation:

Add $86 to the value of -$47.90

-47.9 + 86 = 38.1

The value of h + k is 0 if, on the number line below, the numbers h and k are the same distance from 0 the answer is 0 or zero.

It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.

As we know,

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

It is given that:

On the number line below, the numbers h and k are the same distance from 0.

From the number line.

h = k (the magnitude of the h and k are equal)

There are all negative numbers left side of the zero on a number line.

There are all positive numbers right side of the zero on a number line.

h = -k

The value of h + k

= h + k

Plug the value of h in the above expression:

= -k + k

= 0

Thus, the value of h + k is 0 if, on the number line below, the numbers h and k are the same distance from 0 the answer is 0 or zero.

#SPJ2

Answer:

dividing by 100

Step-by-step explanation:

Step-by-step explanation:

Start by creating expressions

t= A tray of tomato plants

3t = $16.47

Solve the equation above

3t/3= 16.47/3

t= 5.49

A tray of tomato plants costs $5.47

Now create the ratios

b= A tray of basil plants

t:b = 3:2

Substitute t

5.49:b = 3:2

Rewrite as fractions

[tex]\frac{5.49}{b}[/tex] = [tex]\frac{3}{2}[/tex]

Cross multiply

5.49(2) = 3(b)

10.98 = 3b

10.98/3 = 3b/3

3.66 = b

A tray of basil plants costs $3.66

In total she bought 3 trays of tomato plants, which cost $16.47, and 10 trays of basil plants

T0 find out the cost of the 10 basil plants, multiply 3.66 by 10

3.66 × 10 = 36.6

She bought 10 trays of basil plants for $36.60 and 3 trays of tomato plants for $16.47

Add the 2 values together

36.60+16.47 = 53.07

$53.07 is the total

Answer:

The y-intercept in coordinate form is (0, 2.9), which the y-intercept represents the pickup fee which is $2.90 before any mileage

Step-by-step explanation:

Hello, I do apologize that no one responded for two hours.

1 - Understanding what it means to be a y-intercept

When mathematics presents the "y-intercept" its the unimaginative way of saying "Where the equation crosses the y-axis"

Looking at a graph we can deduce that, the y axis in traditional graphs is always at the x value of 0.

What can this mean for this situation?

We want to find out how much each person with 0 miles or no miles driven.

This will be our pickup fee alone

How can we do this?

Theres multiple ways, however the way I like is to set an equation to zero.

2 - Slope Intercept Form

We need to get it into the slope-intercept form using data given to us to use as our equation.

For reference the slope-intercept form is

y = mx + b

y = y value

m = slope

x = x value

b = y - intercept

2.1 - Find the slope

for y = mx + b we'll need to find our slope, m, and to do so we use the following formula

[tex]slope = m = \frac{\triangle y}{\triangle x} = \frac{change~in~y}{chnage~in~x} = \frac{y_2 ~ - ~ y_1}{x_2 ~ - ~ x_1}[/tex]

To do this we need to assign x values and y values.

Our total cost is our y value, because its a total, and our variable is x which will be our miles.

(x value is always the variable, and our y value is always the totals)

So now looking at the data;

Gus;

$12.00 for a 6.5-mile journey

Tony;

$15.50 for a 9-mile journey

We can deduce at 6.5 miles we'll pay $12, and at 9 miles we'll pay $15.50

Because 6.5 is less than 9 our x1 and y1 will be deduced from that, and with that in mind, let's solve that equation.

POINT → (x, y)

(6.5, 12)

(9, 15.50)

[tex]\frac{y_2 ~ - ~ y_1}{x_2 ~ - ~ x_1} = \frac{15.50 ~ - ~ 12.00}{9 ~ - ~ 6.5} = \frac{3.5}{2.5} = 1.4[/tex]

Our slope is 7/5, so therefore,

y = mx + b

      =

y = 1.4x + b

2.2 - Plug and chug to find our y-intercept, b.

We'll need to plug in a point into the unfinished equation to solve for b

y = 7/5x + b

In this instance let's use (6.5, 12)

(x, y)

12 = 1.4(6.5) + b

12 = 9.1 + b

-9.1  -9.1

2.9 = b

Lets plug that in to our y = mx + b

y = 1.4x + b

        ↓

y = 1.4x + 2.9

And would you look at that, just by setting up the equation we now know our y-intercept, now if you recall from earlier one of my notes said this:

POINT → (x, y)

This is the same thing as coordinate form I'm assuming, and as a result, we have all the information we need to answer the problem.

3 - Putting it together to answer the problem

 POINT → (x, y)

           =

Coordinate Form:

           =

        (x, y)

Now remembering what I said earlier, the y-axis, is always on x = 0

So our y-intercept in coordinate form is;

(0, 2.9)

This means;

The pickup fee is $2.90 which excludes any mileage.

See the answer for it put together

Hope this helps :)

Step-by-step explanation:

[tex]\frac{x}{3} - 2 + \frac{x}{2} + 6 = 3\\[/tex]

[tex]\frac{x}{3} - 2 + \frac{x}{2} + 6 = 3[/tex]

[tex]\frac{1}{3} x + -2 + \frac{1}{2} x + 6 = 3[/tex]

[tex]5/6 x + 4 = 3[/tex]

[tex]5/6x + 4−4= 3−4[/tex]

[tex]5/6x = −1[/tex]

[tex](6/5) * (5/6x) = (6/5) * (−1)[/tex]

Answer:

V(hemisphere) = 1072.3in^3

Step-by-step explanation:

To find the volume of a hemisphere, we will have to take the volume of a sphere as a whole and divide it by 2. This is because a hemisphere is half of a sphere.

The volume of a sphere is:

[tex]V(sphere) = \frac{4}{3} \pi r^3[/tex]

Let's plug in the radium of 8 into the equation and solve:

[tex]V(sphere) = \frac{4}{3} \pi (8)^3\\V(sphere) = \frac{4}{3}\pi 512 \\V(sphere) = 2144.660585[/tex]

Now, divide it by 2

V(sphere) = (2144.660585)/2

V(hemisphere) = 1072.3in^3

I hope this helps!!

Answer:

You would divide both by 4

Step-by-step explanation:

16 and 24 are both multiples of 4.

Answer:

8

Step-by-step explanation:

To answer this question, you need to find the common factors of each number. The factors of 16 are 1, 2,4, 8, and 16. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. You then have to find the greatest common factor. In this case, it would be 8.
