What is 20% of 90???
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.

What does A equal: 3(6a+12)=9
Answer:
a = -3/2
Step-by-step explanation:
3(6a+12)=9
Divide each side by 3
3/3(6a+12)=9/3
6a+12 = 3
Subtract 12 from each side
6a+12-12 = 3-12
6a = -9
Divide by 6
6a/6 = -9/6
a = -3/2
3(6a+12)=9
distribute
18a+36=9
subtraction P.O.E.
18a=-27

Answer:
114.6
Step-by-step explanation:
Left Side
It's a rectangle.
L = 12 km
w = 5 km
Area = L*W= = 60
Right Side (top)
It too is a rectangle.
L = 10
W = 3
Area = L*W = 30
Triangles
Area = 1/2 * b * h
Area = 1/2 * 12 * 4.1 24.6
Total Area 114.6

as a decimal number
Answer:
0.391.00Step-by-step explanation:
"100% as a decimal is written as 1.00 as decimal notation.""39% = 0.39 in decimal form. Percent means 'per 100'. So, 39% means 39 per 100 or simply 39/100."Find the slope of the line containing the points whose coordinates are (1/,) and (1/,) a. Ab b. A+b/ab c. 1/ab d. A-b/ab
Answer:
1/ab
Step-by-step explanation:
Complete question
Find the slope of the line containing the points whose coordinates are(a,1/b) and (b,1/a)
Slope is expressed as;
m = y2-y1/x2-x1
Substitute the coordinate values
m = (1/a - 1/b)/b -a
m = (b-a)/ab ÷ b-a
m = (b-a)/ab × 1/b-a
m = b-1/b-a × 1/ab
m = 1 × 1/ab
m = 1/ab
Hence the slope is 1/ab

Christopher's backyard is in the shape of a trapezoid. The bases of the backyard are 30 and 50 feet long. The area of the backyard is 960 square feet. Write and solve an equation to find the height of Christopher's backyard. =12(1+2)ℎ
Answer:
24 feet
Step-by-step explanation:
The formula for the height of a trapezoid =
h = 2A/ a + b
A = 960 square feet
a = 30 feet
b = 50 feet
h = 2 × 960/30 + 50
h = 1920/80
h = 24 feet
please help!!!!!!!!!!!!! due in 5 min!!!!!!!!!!
I don't understand the problem. Can you help me solve it please? I also have an IEP.
Answer:
12
Step-by-step explanation:
The Pythagorean theorem is
a^2+b^2 = c^2 where a and b are the sides and c is the hypotenuse ( the side opposite the right angle)
a^2 + b^2 = c^2
Substitute the known values
5^2 + b^2 = 13^2
25+b^2 = 169
Subtract 25 from each side
25+b^2-25 =169-25
b^2 = 144
Take the square root of each side
sqrt(b^2) = sqrt(144)
b=12
Answer:
Given:
a = 5c = 13To find:
missing side b
Solution:
Using Pythagorean theorem,
(Hypotenuse² = base² + perpendicular²)
b² = c² - a²
= 13² - 5²
= 169 - 25
= 144
b = √144
= 12

1. You start a biology experiment with 4,500 cells. The cells are continuously growing and 2 minutes later
there are about 22583 cells. What is the rate of growth per minute?
Answer:
80.65% per minute
Step-by-step explanation:
For continous growth :
A = Pe^rt
A = amount after time, t
P = initial amount
r = growth rate
22583 = 4500 * e^r*2
22583 = 4500 * e^2r
22583 / 4500 = e^2r
5.0184444 = e^2r
Take the In of both sides
1.61312 = 2r
r = 1.61312 ÷ 2
r = 0.80656
0.80656 * 100% = 80.65%

Herby is a corn farmer in lowa who likes to track the growth of his crops. At various times Herby will go
into the field and document the height of the corn (in cm) and how many weeks it has been since the corn
was planted. He plotted the points below.
He is looking for a function that models his data. Since the trend of the data is increasing and convex, he
found an increasing convex exponential model and an increasing convex quadratic model.
Which of the following functions fits the data better?
Choose 1 answer:
Function A: y = 7.2
B
Function B: y = 1202 – 12x + 18

2 1/10
-2 1/1
-1 1/10
11/10
Answer:
Step-by-step explanation:
slope = m
m = y2-y1 / x2 - x1
m = (-4) - 7 / (-6) - (-4)
m = -11 / (-6) + 4
m = -11 / -2
m = 11/2

Factor out the GCF from the given polynomial. 10^3 + 16^2 - 18x 10^3 + 16^2 - 18x = (Type your answer in factored form.)
Answer:
2x
Step-by-step explanation:
Given the expression 10x^3 + 16x^2 - 18x, we are to find the GCF
First find the factors
10x^3 = 2 * 5 * x * x^2
16x^2 = 2 * 8 * x * x
18x = 2 * 9 * x
From the factors shown, you will see that 2 and x are the common factors. Hence the GCF of the expression is 2x
