Answer: 18
Step-by-step explanation:
First we want to turn 20% into a decimal so we can multiply it by 90.
So to do that we divide 20 by 100.
20/100=0.2 so 0.2 is the decimal form of 20%.
Then we multiply 90 by 0.2 to get 18 as our answer.
Answer:
Answer: 20% of 90 is 18.
Let's find 20% of 90.
Explanation
20% of 90 can be written as 20% × 90
= 20/100 × 90
= 18
Thus, 20% of 90 is 18.

A. 98pi units3
B. 784pi units3
C. 112pi units3
D. 196pi units3
Answer:
D) 196π
Step-by-step explanation:
Volume of a cylinder formula:
V = πr²h
Given:
r = 7

use the graph f(x)=-x^2+8x+20 to determine the values of m for which m= -x^2+8x+m=0 will have two positive roots
Answer:
first root -2 and the second is 10
Step-by-step explanation:
delta=b squared-4ac=64-4(-1)(20)=144>0
then we have 2 +roots
x1= -b+ radical delta/2a =-2
x2=-b - radical delta/2a=10
The value of m for which -x² +8x+m=0 to have two positive roots is m ≤ 0.
What is a polynomial?A polynomial is an expression that involves the addition, subtraction and multiplication of variables.
A quadratic polynomial is a polynomial of degree 2.
Given that:
f(x)=-x² + 8x + 20
To determine the values of m for which -x² +8x+m=0 would have two positive roots
For -x² +8x+m=0 to have two positive roots, m ≤ 0.
The value of m for which -x² +8x+m=0 to have two positive roots is m ≤ 0.

Write the equation in standard form for a circle that has a diameter with endpoints (8,0) and (-8,0)
Answer:
x²+y² = 64
Step-by-step explanation:
The standard form of writing the equation of a circle is expressed as;
(x-a)²+(y-b)² = r² where;
(a, b) is the centre of the circle
r is the radius of the circle
Given the diameter of the circle with endpoints (8,0) and (-8, 0)
d = √(x2-x1)²+(y2-y1)²
d = √(-8-8)²+(0-0)²
d = √(-16)²
d = √256
d = 16
radius r = 16/2
r = 8
The centre of the circle will be the midpoint of the coordinates
M = (8-8/2, 0+0/2)
M = (0/2, 0/2)
M = (0,0)
Hence the centre is at (0,0)
Get the required equation
Recall that (x-a)²+(y-b)² = r²
Substitute the centre and the radius
(x-0)²+(y-0)² = 8²
x²+y² = 64
This gives the required equation

I need help finding the volume of the diameter please help ASAP!!!
Answer:
6885.1 yd^3
Step-by-step explanation:
the shape in the attached image is a sphere.
thus, we are to find the volume of a sphere
Volume = 4/3 nr^3
n = 22/7
r = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
radius = 23.6/2 = 11.8 ft
4/3 x 22/7 x 11,8^3 = 6885.1 yd^3

Answer:
36 i think
Step-by-step explanation:
Assume that the readings at freezing on a bundle of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find the probability of obtaining a reading greater than -0.084°C.
P(Z>-0.084)
Answer:
0.53347
Step-by-step explanation:
We solve the above question using z score formula
z = (x-μ)/σ, where
x is the raw score = -0.084 °C
μ is the population mean = 0 °C
σ is the population standard deviation = 1°C
Z score =x - μ/σ
= -0.084 - 0/1
= -0.084
Probability value from Z-Table:
P(x<-0.084) = 0.46653
P(x>-0.084) = 1 - P(x<-0.084) = 0.53347
The probability of obtaining a reading greater than -0.084°C = P(x > -0.084) =
is 0.53347

Find the approximate area of the lake whose shape is overlaid on the grid below. Each
square of the grid represents one square mile. (3 points)
Answer:
7.5 square miles
Step-by-step explanation:
Begin by counting the number of squares that the lake completely or almost completely covers. There are six of these, as indicated by an X. Then find the squares which are about half covered by the lake. These are indicated by a Y. There are three of these. The remainder of the squares that contain some portion of the lake are less than half covered, so we will not count them.
Irregular Object
1 square = 1 sq. mile
Each X counts as one square mile, and each Y counts as 0.5 (12) of a square mile.
(6 × 1) + (3 × 0.5) = 6 + 1.5 = 7.5
The area of the lake is about 7.5 square miles.

Answer:
c = 88
Step-by-step explanation:
c = 180 - a - b
c = 180 - 43 - 49
c = 137 - 49
c = 88
Answer:
c= 88
Step-by-step explanation:
What you want to do is take (a) which it says is 43 and (b) which it says is 49 and plug them into the equation. Here it says c = 180 - a - b so what you would do is take c=180-43-49 or c=88.

Make q the subject of the formula p = 2q2 .
Answer:
q = ± [tex]\sqrt{\frac{p}{2} }[/tex]
Step-by-step explanation:
Given
p = 2q² ( divide both sides by 2 )
[tex]\frac{p}{2}[/tex] = q² ( take the square root of both sides )
± [tex]\frac{p}{2}[/tex] = q
Answer:
q = +√p/2
Step-by-step explanation:
p = 2q²
divide both sides by 2 and root we get,
√p/2 = √2q²/2
√p/2 = q
q = +√p/2
Thus, q = +√p/2
