Answer:0
Step-by-step explanation:3b(-27 + 9b) = 0
(-27 * 3b + 9b * 3b) = 0
(-81b + 27b2) = 0
Answer:
[tex]b=3[/tex], or [tex]0[/tex]
Step-by-step explanation:
[tex]\mathrm{Using\:the\:Zero\:Factor\:Principle:\quad \:If}\:ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0[/tex]
[tex]b=0\quad \mathrm{or}\quad \:9b-27=0[/tex]
[tex]9b-27=0[/tex], [tex]\mathrm{Add\:}27\mathrm{\:to\:both\:sides}.[/tex]
[tex]9b-27+27=0+27[/tex]
[tex]9b=27[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}9[/tex]
[tex]\frac{9b}{9}=\frac{27}{9}[/tex]

Answer:
245.5 cm²
Step-by-step explanation:
Formula : -
Area of square = side²
Area of square
= 18²
= 324 cm²
Formula : -
Area of circle = πr²
Area of circle
= ( 22 / 7 ) x 5 x 5
= 3.14 x 25
= 78.5 cm²
Area of shaded region
= ( Area of square ) - ( Area of circle )
= 324 - 78.5
= 245.5 cm²

The sum of two numbers is -4.5. Six less than twice the value of the first number is equal to the second number. Find the numbers.
Answer:
first is 3.5, second is 1
Step-by-step explanation:
-4.5 = x + 2x - 6
-4.5 - 6 = 3x
10.5 = 3x
10.5/3 = x
3.5 = x

Answer: <B= 101, <C= 79, <D=101
Step-by-step explanation: all parallelograms have the diagonal angles equal so that is why <c=79. Parallelograms also have all angles equal to 360. so if you add <C, and <A you have 158. then you subtract that from 360 and you get 202. You then need to divide it by to to get the measures of angles B and D which are 101 each.

Answer:
962.5 ft²
Step-by-step explanation:
Area of landing pad = Area of circle
d = 35 ft, r = 35/2 ft
Area = [tex]\pi r^2[/tex]
[tex]\pi r^2[/tex] = [tex]\frac{22}{7} * \frac{35}{2}* \frac{35}{2}[/tex]
= 962.5 ft²
Thus area of landing pad = 962.5 ft²
How far apart are the points (0,-1) and (6,5)?
Answer:
(6, 6)
Step-by-step explanation:
Answer:
The distance is 8.4853
Step-by-step explanation:
Input Data :
Point 1 (xA, yA) = (0, -1)
Point 2 (xB, yB) = (6, 5)
Objective :
Find the distance between two given points on a line?
Formula :
Distance between two points = √(xB − xA) ^ 2 + (yB − yA) ^ 2
Solution :
Distance between two points = √ (6 − 0)^2 + (5− −1) ^ 2
= √6^2 + 6^2
= √36 + 36
= √72
= 8.4853
Distance between points (0, -1) and (6, 5) is 8.4853
hope this helps and is right :)
5. Chante was very cold. She wanted to wear her new jacket with the pink
flowers on it. Her mother said that it was negative seven degrees Celsius
but that it was going to be eleven degrees Celsius by afternoon. How many
degrees would the temperature have to rise to reach eleven degrees
Celsius? Convert 11 degrees Celsius to Fahrenheit.
Step-by-step explanation:
To find how many degrees the temperature would have to rise you need to do 11 - (-7) which is equal to 18. So the temperature rose 18 degrees.
To convert Celsius to Fahrenheit you need to do
(C * 9/5) + 32. In this case it would be (11 * 9/5) + 32 which results in 51.8 degrees Fahrenheit.

Answer:
B reflected over y, translated up
Step-by-step explanation:
The left-right reversal means there was a reflection over a vertical line. The only one among the offered choices is the y-axis.
If the lines are reflected over the y-axis, the points on the y-axis don't move. The intercepts would still be 2 and 5 after the reflection.
However, the y-intercepts have moved up 3 units to 5 and 8.
Lines g and h were reflected over the y-axis and translated up 3 units.

Answer:
w = 21
Step-by-step explanation:
Given that,
game 1 game 2
Points 12 18
Shots 14 w
One proportion is : [tex]\dfrac{12}{14}=\dfrac{6}{7}[/tex]
Other proportion is : [tex]\dfrac{18}{w}[/tex]
So,
[tex]\dfrac{6}{7}=\dfrac{18}{w}\\\\w=\dfrac{7\times 18}{6}\\\\w=21[/tex]
So, the value of w is equal to 21.

Please Help Jane has 10 cards Jane is going to make a row containing four cards how many unique ways can she ordered the row
it will be 151200 is the anwser
There will be a total of 5040 unique ways to make arrangements of 4 cards out of 10 so option (A) will be correct.
What are permutation and combination?When the order of the arrangements counts, a permutation is a numerical approach that establishes the total number of alternative arrangements in a collection.
The number of alternative configurations in a collection of things when the order of the selection is irrelevant is determined by combination.
Given the 4 cards arrangement out of 10
npr = n! /(n-r)!
Here n = 10 , r = 4
10p4 = 10! /(10-4)!
10p4 = 10 × 9 × 8 × 7 × 6! /6!
10p4 = 5040
So there will be a total of 5040 ways to arrange the cards.
