Answer:

(1, 5)

Step-by-step explanation:

The midpoint of a line segment has coordinates that are the average of the end-point coordinates.

M = (X + Y)/2 = ((-3, 4) +(5, 6))/2 = (-3+5, 4+6)/2 = (2, 10)/2

M = (1, 5)

The midpoint is (1, 5).

Delvig [45]

Answer:

The height of the building is $73.2\ ft$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC

$tan(38\°)=\frac{BC}{AB}$

we have

$AB=63\ ft$

substitute and solve for BC

$tan(38\°)=\frac{BC}{63}$

$BC=(63)tan(38\°)=49.2\ ft$

Find the height of the building

The height of the building (h) is equal to

$h=BC+24=49.2+24=73.2\ ft$

You use 4 gallons of water on 30 plants. At that rate how much water will you need for 45 plants?

Alja [10]

You would use 6 gallons of water to water 45 plants
4=30
$\frac{45}{30}$ = $\frac{3}{2}$
$\frac{3}{2}$ of 4 gallons = 6 gallons

Some members of the cooking club are making cakes which they will sell at a street fair for $10 apiece. It costs $10 for a booth

Alika [10]

Answer:

The cooking club sales covers the expenditure when 2 piece of cakes are sold.

Step-by-step explanation:

Given:

Selling price of each piece of cake = $10

Cost for booth at fair = $10

Ingredients for each piece of cake = $5

We need to find the number of pieces of cake sold when the sales cover the expenditures.

Solution:

Let the number of pieces be 'x'

So We can say that the point at which the sales cover the expenditures can be calculated as Selling price of each piece of cake multiplied by number of pieces will be equal to Cost for booth at fair plus Ingredients for each piece of cake multiplied number of piece of cakes.

framing in equation form we get;

$10x =10+5x$

Now Subtracting both side by '5x' using Subtraction property we get;

$10-5x=10+5x-5x\\\\5x=10$

Now Dividing both side by 5 we get;

$\frac{5x}{5}=\frac{10}{5}\\\\x=2$

Hence The cooking club sales covers the expenditure when 2 piece of cakes are sold.
