Simplify. Multiply and remove all perfect squares from inside the square roots. Assume z is positive. z* 30z2* 35z3
Answer:
[tex]5z^3\sqrt{42}[/tex]
Step-by-step explanation:
You can multiply and put everything under one square root to get [tex]\sqrt{1050z^6}[/tex]. You can take out [tex](5z^3)^2[/tex] from the square root to get [tex]\boxed{5z^3\sqrt{42}}[/tex]
Find the value of x.
Answer:
45 degrees
Step-by-step explanation:
Before we start, it is important to know that the sum of all angles of a triangle adds up to 180. Since one of the angle measure is already given to us, 90, we can subtract this from 180.
180-90=90
This tells us that the two remaining angles will add together to equal 90. In addition, it also tells us that the two remaining angles are equal. This means we can divide 90 by 2, and it leaves us that x= 45 degrees.

GEOMETRY. I will give brainliest
Answer:
15 (3rd option)
Step-by-step explanation:
Circumference formula=2 x pi x r(radius)
So, 30 pi = 2 pi r
Next, isolate the r(radius)
30 pi / 2 pi = r
The 2 pi's cancel out and leaves 30/2
r=15
Joshua went to the grocery store and purchased cans of
soup and frozen dinners. Each can of soup has 200 mg
of sodium and each frozen dinner has 400 mg of sodium.
Joshua purchased a total of 10 cans of soup and frozen
dinners which collectively contain 2400 mg of sodium.
Write a system of equations that could be used to
determine the number of cans of soup purchased and
the number of frozen dinners purchased. Define the
variables that you use to write the system.
Answer:c + f = 10
200c + 400f = 2400
Step-by-step explanation:
Let's say c is the number of cans of soup and f is the number of frozen dinners.
The total number of items is 10:
c + f = 10
The total amount of sodium is 2400 mg. Each can of soup has 200 mg, and each frozen dinner has 400 mg.
200c + 400f = 2400
The problem doesn't ask you to solve the system, but I'll solve it anyway. We can use substitution or elimination. But first, simplify the second equation by dividing both sides by 200.
c + 2f = 12
Using elimination, subtract the first equation.
f = 2
Plug into either equation to find c:
c = 8
There are 8 cans of soup and 2 frozen dinners.

y is inversely proportional to V1+x.
When x=8, y = 2.
Find y when x = 15.
Please help me with this real quick!
Answer:
y = 1.5
Step-by-step explanation:
Given y is inversely proportional to [tex]\sqrt{1+x}[/tex] , then the equation relating them is
y = [tex]\frac{k}{\sqrt{1+x} }[/tex] ← k is the constant of variation
To find k use the condition when x = 8, y = 2 , then
2 = [tex]\frac{k}{\sqrt{1+8} }[/tex] = [tex]\frac{k}{\sqrt{9} }[/tex] = [tex]\frac{k}{3}[/tex] ( multiply both sides by 3 )
6 = k
y = [tex]\frac{6}{\sqrt{1+x} }[/tex] ← equation of variation
When x = 15, then
y = [tex]\frac{6}{\sqrt{1+15} }[/tex] = [tex]\frac{6}{\sqrt{16} }[/tex] = [tex]\frac{6}{4}[/tex] = 1.5
Find the slope of the line

please answer and show step.
Answer:
i believe the answer is 25.
Step-by-step explanation:
this is because if a=how much money deposited after t= depositing weekly and 16 is being multiplied by t. that leads me to believe she deposits $16 weekly. therefore, her original deposit was $25.
tell me if this is incorrect.
Answer:
25
Step-by-step explanation:
In this equation, the original deposit was 25 dollars. The equation shows how much total money was in the account every week. It is written in slope-intercept form, which is y=mx+b, where m is the slope (how much the account is increasing each week) and b is the y-intercept (what was in the account after 0 weeks). This means 25 dollars must be the initial deposit because it is the total before any new weekly deposits.

25 points. Need help with this math question
Answer:
1 kilometer is 1000 meters
1 hectometer is 100 meters
1 dekameter is 10 meters
1 meter is 1 meter
1 decimeter is 0.1 meters
1 millimeter is 0.001 meters
Answer:
1 kilometer = 1000 meters
1 hectometer = 100 meters
1 dekameter = 10 meters
1 meter = 1 meter
1 decimeter = .1 meter
1 centmeter = .01 meter
1 milimeter = .001

You need to convert those units to other units, the most common way is to have a table with different factors. I would recommend the one of cm, mt, km, m/h. You can find those on internet.
Triangle QRS is a right triangle.
What is the lenghts of RS.
0 10
0 7.1
05.3
0 14
Answer:
5.3
Step-by-step explanation:
a² + b² =² c² the Pythagorean theorem
RQ² + RS² = QS² Solve RS
6² + RS² = 8²
RS² = 64 -36
RS² = 28
RS = √28 28 is slightly > 25 and since √25 =5
RS = 5.3 actually 5.2915 to a few more significant digits

why is the equation y = mx + b called the slope - intercept form?
Answer:
Step-by-step explanation:
The equation y = mx + b is called the slope-intercept form because both the slope and y-intercept are represented. The variable m, stands for slope, and the variable b, stands for slope.

Erica can thoroughly analyze the company’s monthly credit card statements
in 80 minutes. It takes Alexa 2 hours to do the same job. One afternoon, Erica and Alexa start analyzing the company’s credit card statements together. Half an hour later, Mack, the new employee, joins them. If the three of them finish 15 minutes later, how long would it have taken
Mack to analyze the company’s monthly credit card statements on his own?
Answer:
240 minutes or 4 hours
Step-by-step explanation:
So if it takes Erica 80 minutes to analyze the company's monthly credit card statements, she will get 30/80 of it done in 30 minutes.
If it takes Alexa 2 hours to analyze the company's monthly credit card statements, she will get 30/120 of it done in 30 minutes.
Add 15 to each of the fractions because they analyze the company's monthly credit card statements with Mack for 15 more minutes.
So you have 45/80 and 45/120.
Now add both fractions by finding the lowest common denominator which is 240.
135/240 + 90/240 = 225/240
So Mack did the remaining 15/240.
Now to find how long it would take him to analyze the company's monthly credit card statements by himself divide 240 by 15 which is 16.
Then multiply
15 x 16 = 240
so it would take him 240 minutes or 2 hours.

Answer is 16 because 16/4 = 4 + -12 = -8
Answer:
m=16
Step-by-step explanation:
-8=m/4+(-12)
4=m/4
16=m
so first, you add 12 to the other side to cancel out the -12. 12-8=4. so now you have 4=m/4. to isolate the m, you have to multiply by 4 on both sides, which gives you 16=m or m=16.
