Answer:

V = 4 2/3 units ^3

Step-by-step explanation:

We are given the area of the back rectangle

V = BH where B is the area of the base

V = 3 1/3 * 1 2/5

Rewriting the mixed numbers as improper fractions

V = 10/3 * 7/5

V = 70/15

Simplifying

V = 14/3

Changing back to a mixed number

V = 4 2/3 units ^3

Answer:

44°

Step-by-step explanation:

180° - 68° = 112° (Angle 1)

The sum of the angles of a triangle is equal to 180°, so:

180° - 112° - 24° = 44°

Answer: A????????????

Step-by-step explanation:

you need to show the following

Since the price has been increasing by $7 per month, the rate at which revenue is changing when the price is $70 is $24500/month

To answer the question, we need to know what revenue is

This is the total price for the total amount of goods sold.

Revenue, R = px where

So, R = px

= p(77000 - 5p²)

= 77000p - 5p³

To find the rate at which the revenue is increasing with respect to price, we differentiate R with respect to p.

So, dR/dp = d(77000p - 5p³)/dp

= 77000dp/dp - 5dp³/dp

= 77000 - 15p²

Substituing p = 70 into dR/dp, we have

dR/dp = 77000 - 15p²

dR/dp = 77000 - 15(70)²

= 77000 - 15(4900)

= 77000 - 73500

= 3500

The rate at which the revenue is changing per month is

dR/dt = dR/dp × dp/dt where dp/dt = rate at which price is changing = $7 per month.

Now, dR/dt = dR/dp × dp/dt

So, dR/dt = 3500 × $ 7/month

dR/dt = $24500/month

So, the rate at which revenue is changing when the price is $70 is $24500/month

Answer:

x = 5/2 or x = 6

Step-by-step explanation:

(2x)(2x)=(x+10)(2x-3)

4x^2 = 2x^2 - 3x + 20x - 30

2x^2 - 17x + 30 = 0

(2x - 5)(x - 6) = 0

x = 5/2 or x = 6

The sum of the external side of a figure is its perimeter.  the perimeter of the larger flag is 48

Shapes are known to be similar if the ratioof their similar sides is equal to a constant.

From the given diagram, find the scale factor of the large triangle

k = 12/4

k = 3

Determine the perimeter of the large flag

Perimeter = 3 * perimeter of small flag

Perimeter of large flag = 3 * 16 = 48

Hence the perimeter of the larger flag is 48

Answer:

The Answer is 8m square

Step-by-step explanation:

2m is the width

4m is the length

Answer:

52m²

Step-by-step explanation:

First since its only showing the front, top, and right side of the shape you count up all of the cubes you see.

Amount of cubes on each side:

Front: 6 cubes

Top: 8 cubes

Side: 12 cubes

6+8+12=26 cubes

But there is 6 sides total on the shape. Because we only did 3 sides, to get the final answer you multiply it by 2.

26×2=52

Final answer: 52m²

[tex](x + 3)^2 + (y - 5)^2 = 5^2[/tex]

Step-by-step explanation:

Well, the center origin of the circle is given (h,k) =  (-3,5).

Point on the circle is (x,y) = (1,8)

We have to find our radius as they gave us a point. from origin to the edge of the circle.

Using the formula: (x - h)^2 + (y - k)^2 = r^2

Plug in our (h,k) = (-3,5) and (x,y) =  (1,8) to solve for radius.

(x - h)^2 + (y - k)^2 = r^2

(1 - (-3))^2 + (8 - (5))^2 = r^2

(4)^2 + (3)^2 = r^2

16 + 9 = r^2

r^2 = 25

r = 5

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

The good maximum sample size is usually around 10% of the population, as long as this does not exceed 1000.

The sample size will be calculated as:-

=   10 % of 800

=  800 x  0.1 = 80 students
