Hi I need help on this I've been working on it for about 20 minutes now please help :)
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:
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

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°

(2x)(2x)=(x+10)(2x-3) what is x?
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

A company has found that the number of items sold, x, depends upon the price, p at which they're sold, according the equation x=77000−5p^2
The price has been increasing by $7 per month. Find the rate at which revenue is changing when the price is $70. Note: the answer might be negative
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
What is revenue?This is the total price for the total amount of goods sold.
Revenue, R = px where
p = price and x = quantity = 77000 - 5p²So, R = px
= p(77000 - 5p²)
= 77000p - 5p³
The rate at which the revenue is increasing
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
The rate at which the revenue is changing with the price is $70
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
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

Write the equation of a circle with center (-3, 5) and a point on the circle is (1, 8).
Equation:
Answer:
[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

80 students
50 students
8 students
85 students
The best representation of the preferences of all the students at her school will be 80 students.
What is probability?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
