Step-by-step explanation:
Simply the following: [tex]-3\sqrt{50a^{2} b^{2} }[/tex]
Given:
The expression is
[tex]-3\sqrt{50a^2b^2}[/tex]
To find:
The simplified form of the given expression.
Solution:
We have,
[tex]-3\sqrt{50a^2b^2}[/tex]
It can be written as
[tex]=-3\sqrt{2\times 25a^2b^2}[/tex]
[tex]=-3\sqrt{2\times 5^2a^2b^2}[/tex]
Using the properties of radical and logarithm, we get
[tex]=-3\sqrt{2\times (5ab)^2}[/tex] [tex][\because (mn)^x=m^xn^x][/tex]
[tex]=-3\sqrt{2}\times \sqrt{(5ab)^2}[/tex] [tex][\because \sqrt{mn}=\sqrt{m}\sqrt{n}][/tex]
[tex]=-3\sqrt{2}\times 5ab[/tex]
[tex]=-15\sqrt{2}ab[/tex]
Therefore the simplified form of the given expression is [tex]-15\sqrt{2}ab[/tex].

in a complete sentence, describe the angle relationship
Fine the value of x
Answer:
30
Step-by-step explanation:
90+2x+x=180
3x=90
x=30
Answer:
30
Step-by-step explanation:
First we can find the total angle that we are "adding" to. This total angle is 180 degrees. Now since there is a right angle, H,E,G, we can remove 90 from that total to get 90. Now for x. Since there is a total of 3 x's, we divide 90 by 3 to get 30.

Which of the following objects show an OBTUSE angle?
2 + 6m + 7 = 57
pls show your work pls.
i need a full answer
Answer:
m=8
hope this helps
have a good day :)
Step-by-step explanation:
2 + 6m +7=57
9+6m=57 add like terms
6m=48 subtract 9 from each side
m=8 divide by 6 on each side
Answer:
M=8
Step-by-step explanation:
First your going to subtract 2 from 7 and thats 5.
then your going to do:
6m+5=57
Then subtract 5 from 57 and thats 52
and divide 52 from 6 and thats 8.
question “If y =5, what is the value of the following expression

Identify a set of parallel lines and a set of perpendicular lines in this image
Answer
It is the first answer.
Step-by-step explanation:
Parallel lines are lines that will never cross each other.
Perpendicular lines are lines that cross each other at 90 degree angles (represented by the box in the corner).
A set of parallel lines and a set of perpendicular lines in this image are; AB║CD, CD ⊥ EF and AB ⊥ EF
How are parallel straight lines related?Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.
Since Parallel lines are lines that will never cross each other.
We know that Perpendicular lines are lines that cross each other at 90 degree angles.
The parallel lines are AB and CD, the perpendicular are AB and EF because the first sets are side by side and the second sets cross each other at a certain point.
Therefore the set of parallel lines and a set of perpendicular lines in this image are; AB║CD, CD ⊥ EF and AB ⊥ EF

Step-by-step explanation:
which value of x makes the equation 1.25(4 x-10)=7.5 true?
A. 3.5
B. -1
C. -0.5
D. 4
Answer:
4
Step-by-step explanation:
1.25(4x-10)=7.5
First step is to divide the 1.25 on both sides
4x-10 = 6
next step is to get x by itself by adding 10 to both sides
4x = 16
continue getting x by itself by dividing both sides by 4
x = 4.
Andrew collects coins. He collected a total of 275 coins. If 84% of the coins he collected were foreign, how many other coins did he collect? Andrew collected coins that were not foreign
Answer:
44
Step-by-step explanation:
1. Find out how many coins were foreign
x. 84
------ = ---------
275. 100
2. Subtract 231 (Foreign coins) by 275 (Total coins)
3. The answer is 44
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
The number of foreign coins.
84% of 275 = 231
The number of foreign coins is 231.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Total number of coins = 275
Percentage of foreign coins = 84%
The number of foreign coins.
= 84% of 275
= 84/100 x 275
= 231
Thus,
The number of foreign coins is 231.

Write equation of a line parallel or to a y=2x+3 that passes the ordered pair (3,6)
Answer:
y = 2x
Explanation:
To write the equation of a line u use the formula y = mx + b, where
y = y coordinate
m = slope
x = x coordinate
b = y intercept
One thing about parallel lines is that they always have the same slope. If you want to find a line parallel to y = 2x + 3, then the parallel line will also have a slope of 2.
So far, then, the equation would look like this: y = 2x + b
To find the y-intercept, we substitute in the values from (3,6) into the equation because the line passes through that point. So:
y = 2x + b
(6) = 2(3) + b
6 = 6 + b
6 - 6 = b
b = 0
Since the y-intercept is 0 (so the line passes through the origin), it doesn't need to be written on to the end of the equation.
y = 2x + 0 is just
y = 2x
That's your final equation! hope this helps!

Answer:
362.35N/m²
Step-by-step explanation:
Pressure = Force/Area
Area = πr²
Area = 3.14(0.75)²
Area = 3.14(0.5625)
Area = 1.76625m²
Force = 640N
Pressure = 640/1.76625
Pressure = 362.35N/m²
Hamburger Heaven is having a lunch special where customers buy one 3/4-pound cheeseburger and get one free. If they set aside 130 2/3 pounds of meat, how many 3/4-pound cheeseburgers can they make?
Answer:
174 cheeseburgers
Step-by-step explanation:
The computation of the number of 3 by 4 pound cheese burgers made is shown below:
3 by 4 would be written as 0.75 pound
And, 130 2 ÷ 3 = 130.66667 pounds
Now the number of 3 by 4 pound cheese burgers made is
= 130.66667 pounds ÷ 0.75 pound
= 174.22
= 174 cheeseburgers

Write the equation of the line in slope intercept form that has a slope of -1/5 and contains (-5,-3)
Answer:
y = [tex]-\frac{1}{5}x[/tex] - 4
Step-by-step explanation:
As we know the point slope form of an equation is as follows -
y - y₁ = m ( x - x₁ )
As we have slope , m = [tex]-\frac{1}{5}[/tex]
And point (x₁ , y₁ ) = ( -5, -3)
⇒ y - ( -3) = [tex]-\frac{1}{5}[/tex] ( x - (-5) )
⇒ y + 3 = [tex]-\frac{1}{5}[/tex] ( x + 5 )
⇒ y + 3 = [tex]-\frac{1}{5}[/tex] x - 1
⇒ y = [tex]-\frac{1}{5}[/tex] x - 1 - 3
⇒ y = [tex]-\frac{1}{5}[/tex] x - 4
So, the equation becomes
y = [tex]-\frac{1}{5}x[/tex] - 4
