b)what is the simplified form of 2² X 2⁵ (with explanation please)
Answers
Answer:
Step-by-step explanation:
Perimeter of square park = 2000 m
4*side = 2000
side = 2000 ÷ 4
side = 500 m
Area of square park = side * side
= 500 * 500

If I have 20 shares of a stock worth a total value of 440.80 what is the price per share of the stock?
If my total value dcreases by 6% what is it now?
Answers
Answer:
The price per share of the stock is 22.04. If the total value decreases by 6% the price becomes 20.71.
Step-by-step explanation:
440.80/20= 22.04
100-6= 94%
0.94 x 440.80= 414.35
414.35/20= 20.71
The City of Killeen utilities charges for water usage per gallon on a monthly basis as listed below.
Up to 500 gallons ($0.15/gallon)
More than 500 gallons - 1000 gallons ($0.33/gallon)
How much will Mrs Lapid pay if she uses 795 gallons in a particular month?
Answers
Answer:
$262.35
Step-by-step explanation:
From the above question we are given the cost for a given range of gallons
Mrs Lapis uses 795 gallons, hence this falls into the range of:
More than 500 gallons - 1000 gallons ($0.33/gallon)
Hence:
1 gallon = $0.33
795 gallons = $x
Cross Multiply
1 gallon × $x = $0.33 × 795 gallons
$x = 795 × $0.33
x =$ 262.35
Therefore, Mrs Lapis would pay $262.35 every month

Calculate the value of p and the value of q
Answers
Answer:
q= 20 p= 56
Step-by-step explanation:
A angle is also 62°
Answer:
q = 20 degrees
p = 59 degrees
Step-by-step explanation:
to find q, find all the other interior angles within that shape and subtract it from 360
angle E = 180 - 62 = 118
angle b = 90
angle c = 132
360 - (118 + 90 + 132) = 20
angle q = 20 degrees
to find p, add all the other interior angles within that shape and subtract it from 180
angle e = 62 degrees
angle a and b are the same so, take 62 and subtract it from 180 then divide the answer by 2
180 - 62 = 118
118 / 2 = 59
angle a = 59 degrees
angle p = 59 degrees

Write an equation that could be used to find the value of x using the interior angles of ∆ABD, then solve the equation.
Answers
Answer:
equation: 55 + (2x + 3) + 90 = 180
55 + 2x + 3 + 90 = 180
2x + 148 = 180
2x = 32
x = 16
Answer:
55 + 50 + 2x+3 + 2x+8 = 180
x = 16
Step-by-step explanation:
55 + 50 + 2x+3 + 2x+8 = 180
113 + 4x = 180
4x = 64
x = 16
In degrees, what is the measure of MFE?
Answers
Answer:
30°
Step-by-step explanation:
It tells us that MFE is equal to (x + 6)° so we need to find x
The angle accross from MFE is RFT. These angles are congruent, because they are a vertical pair. So RFT is also equal to (x + 6)°
The angle RFT and PFR combined form a right angle. This means that RFT + PFR = 90°.
They told us that PFR = (3x - 4)°
so that means that (x + 6) + (3x - 4) = 90°
Knowing that we can just solve the equation by combining like terms
4x + 2 = 90
Subtract two from both sides
4x = 88
And then divide by 4
x = 22
Now we can plug in 22 in the original equation to find MFE
22 + 6 = 30
so MFE = 30°

HURRYYY A company is introducing a new product. The equation y = –0.001(x – 600)2 + 90 predicts the expected profit, in thousands of dollars, where x represents the number of thousands of units of the product sold by the company. How many units must be sold to yield a maximum profit? 90 600 90,000 600,000

Step-by-step explanation:

The amount of units that must be sold to a number yields a maximum profit is 600. Hence 600 units will be the correct option.
How to find maxima?To find the maxima of any function it needs to differentiate with respect to the dependent variable and equate with zero to get stationary points.
After achieving the stationary points it needs to put on the double derivative of that function to check whether it's maxima or minima.
If the double derivative got negative then it will be maxima.
Given that function
f(x) = -0.001(x-600)² + 90
By differentiation
[tex]$f'(x)$[/tex] = -0.002(x - 600) + 90
Now equate with zero
-0.002(x - 600) + 90 = 0
x - 600 = 0
x = 600
Now checking the x at double derivative
[tex]$f''(x)$[/tex] at x = 600 it is coming out to -0.002 which is negative Hence, the 600 units will be the correct answer.
