Which is equivalent to the square root of 54.
Answer:3[tex]\sqrt{6}[/tex]
We first need to break up 54 into prime factors. An easy way to do this is two divide by something like 2 or 3 and repeating the process until you end up with all prime numbers. Simplifying 54 would look something like this. 54 = 27*2 , 27 = 9*3 , 9 = 3*3
We now take all the prime factors we have there and rewrite it into [tex]\sqrt{54}[/tex] = [tex]\sqrt{2*3*3*3}[/tex]. We have to take out each pair of the same factor we see since its the square root. Resulting in [tex]3\sqrt{2*3}[/tex] Simplify the inside and we finally get the answer of 3[tex]\sqrt{6}[/tex]

State the property that justifies the statement: If 4x + 9 = 15 and X=2y + 1,
then 4(2y+1) + 9 = 15.
Distributive Property
Multiplication Property of Equality
Transitive Property of Equality
Substitution Property of Equality
Answer:
Substitution property of equality
Step-by-step explanation:
Given
[tex]4x + 9 = 15[/tex] and [tex]x = 2y + 1[/tex]
Then
[tex]4(2y + 1) + 9 = 15[/tex]
Required
State the property
From the list of options, (d) answers the question.
This is so because:
Substitution property of equality states that
If [tex]a = b[/tex] then [tex]b = a[/tex]
In other words, both can replace one another.
So if [tex]x = 2y + 1[/tex], then 2y + 1 can be substituted for x in [tex]4x + 9 = 15[/tex]
So:
[tex]4x + 9 = 15[/tex] becomes
[tex]4(2y + 1) + 9 = 15[/tex]
Hence, it is substitution property of equality
HELP!!!!!!! The area of the rectangle shown below is 24 square centimeters. What is the area, in square centimeters, of the shaded triangle?
Answer:
is it multiple choice?
Step-by-step explanation:
The area of the rectangle given is 24 square centimeters. Hence, The area of the shaded triangle will be 12 square centimeters.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
The area of the rectangle given is 24 square centimeters.
The area of the rectangle = length × Width
24 = a x b
Also, a = 24/b
The area of the shaded region is equal to the area of the triangle.
So, The area of the triangle = 1/2 x b x h
= 1/2 x (a) x b
= 1/2 x 24
= 12
Hence, The area of the shaded triangle will be 12 square centimeters.

you have the choice b, the legs are adjacent to the right angle
(x+8)(x+2) = 10x+x^2
Answer:
.
Step-by-step explanation:
x^2 + 2x + 8x + 16 = 10x + x^2 (FOIL)
x^2 + 10x + 16 = 10x + x^2 (add like terms)
16 = 0 (10x and x^2 cancel out on both sides)
(x+8)(x+2) is NOT equal to 10x+x^2

1) What is the maximum number of mini Snickers you could buy?
2) What is the maximum number of Kitkats you could buy?
3) How do these maximums relate to the x and y-intercepts of the standard form linear equation that could be used to model this situation?
Answer:
1. 60 snickers
2. 20 KitKats
i cannot anwser 3 cause its not showing up somehow. Sorry.
Step-by-step explanation:
Answer:
1) 60 Mini Snickers
2) 20 Kitkats
3) We know that the x intercept is the value of x when y is 0. We also know that the Y intercept is the value of y when x is 0. Both maximums can represent either a y or x intercept because they are the value when you don't have any money left or $0.
Step-by-step explanation:
1) 15 ÷ 0.25= 60

How do I solve this ?
Answer:
See attachment :D
Step-by-step explanation:
y = 2/3x + 2
This is in slope-intercept form, y = mx+b. m is the slope, 2/3, and b is the y- intercept, 2. So you know the line intersects with the y-axis at (0,2). The slope is 2/3. So you can move up two points, then over three. Because it's a positive slope, you move right. This leaves you at point (0,3). Connect a line between these two points.
The line intersects with points (-3,0) and (0,2).

Help! It's geometry. :) 35 points.
Answer:
g = 21
h = 8
Step-by-step explanation:
3g + 5 + 6g - 14 = 180 (since they are adjacent angles and will equal 180)
Simplify to get g = 21.
Substitute 21 for g in 3g + 5 and set that equal to 9h - 4 and solve for h to get 8 (since they are opposite angles and will equal each other)
Answer:g=21 h = 8
Step-by-step explanation:
That's a rhombus supposedly so the opposite angles are congruent.
This means 9h-4=3g+5 Also the opposite sides of a rhombus add up to 180 degrees, so 3g+5+6g-14=180
9g=,189 g = 21
now plug this into the first equation
9h-4=3(21)+5
9h-4=63+5
9h=72
h=8

Step-by-step explanation:
Kristina, Liz, and Heather all made cookies. Kristina made 1.8 dozen less than 6 times as many dozen as Heather. Liz made 2.7 dozen more than 5 times as many dozen as Heather. If Kristina and Liz made the same number of cookies, how many dozen cookies did Heather make?
Answer:
Based on the number of cookies each girl made and if Kristina and Liz made the same number of cookies, then Heather made 4.2 dozen cookies.
Step-by-step explanation:
In order to find the number of cookies that Heather made, you need to set up two equations that represent the number of cookies that Kristina and Liz each made. Since Kristina made 2.4 dozen less than 6 times as many dozen as Heather, we can represent that with the equation 6c - 2.4. Since Liz made 1.8 dozen more than 5 times as many dozen as Heather, we can represent that with the equation 5c + 1.8. We can set both equations equal to each other since Liz and Kristina made the same number, so 6c - 2.4 = 5c + 1.8. Solving for 'c', which represents how many dozen cookies Heather made, we get 4.2

A plane set off to Portland at a speed of 232 mph. On the
return flight of 12 hours, the plane cruised at 204 mph.
How many hours long was the flight to Portland?
Answer:
The flight to Portland takes 10.6 hours.
Step-by-step explanation:
To find the time of flight to Portland we need to calculate the distance traveled by using the equation:
[tex] x = v*t [/tex]
Where:
v: is the speed = 204 mph (return flight)
t: is the time = 12 h (return flight)
[tex] x = v*t = 204 mi/h*12 h = 2448 mi [/tex]
Now, we can find the time of flight to Portland using v = 232 mph:
[tex]t = \frac{x}{v} = \frac{2448 mi}{232 mi/h} = 10.6 h[/tex]
Therefore, the flight to Portland takes 10.6 hours.
I hope it helps you!

. Jaime's hourly wage is $16 and her net pay is 65% of her earnings. Jaime spends about $1,300 on her monthly
expenses. If Jaime works 40 hours per week and has no other sources of income, what is her total monthly cash
inflow? (Hint: Assume that there are 4 pay periods per month.)
Answer:
Monthly income is $1664, positive balance each month is $364Step-by-step explanation:
Hourly wage = $16Net pay = 65%Monthly spending = $1300Work hours = 40 hours per week = 4*40 = 160 hours per monthMonthly earning:
160*16 = 2560Monthly net payment:
$2560*0.65 = $1664Remaining balance per month after expenses:
$1664 - $1300 = $364
