Answer:
9[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Simplify the radicals
[tex]\sqrt{20}[/tex]
= [tex]\sqrt{4(5)}[/tex]
= [tex]\sqrt{4}[/tex] × [tex]\sqrt{5}[/tex]
= 2[tex]\sqrt{5}[/tex]
[tex]\sqrt{45}[/tex]
= [tex]\sqrt{9(5)}[/tex]
= [tex]\sqrt{9}[/tex] × [tex]\sqrt{5}[/tex]
= 3[tex]\sqrt{5}[/tex]
Then
3[tex]\sqrt{20}[/tex] + [tex]\sqrt{45}[/tex]
= 3(2[tex]\sqrt{5}[/tex] ) + 3[tex]\sqrt{5}[/tex]
= 6[tex]\sqrt{5}[/tex] + 3[tex]\sqrt{5}[/tex]
= 9[tex]\sqrt{5}[/tex]

[tex]m= 14 \sqrt 2, \: n = 14[/tex]
Step-by-step explanation:
Hope it helps you in your learning process.
Given is a 45°-45°-90° triangle.
Measure of sides n and 14 are opposite to 45° degree angles.
Therefore, they are equal.
So, n = 14
[tex] 14 = \frac{1}{\sqrt 2}\times m[/tex]
[tex] 14 \sqrt 2=m[/tex]
what is a way that i can get 3x and 2x to cancel out in this problem? i need to get - 5y = -13 and + 15y = -3 alone.
problem:
3x + 5y = -13
2x + 15y= 3
Answer:
For 3x + 5y = -13 the answer is x= -13/3 + 5y/3
and for 2x + 15y=3 the answer x= 1.5 + (-15y/2)
Step-by-step:
For 3x+5y=-13 you have to add 5y on both sides. Then you have to divide by 3 on both sides and cancel out the common factor of 3. Then you would get x= 13/3 + 5y/3.
For 2x + 15y=3 you have to subtract 15y on both sides of the equation. You should have 2x=3 + (-15y). Then divide by 2 on both sides. 3 divided by 2 is 1.5 and -15y divided by 2 is -15y/2 since 2 doesn't have the same variable. so the answer should be x= 1.5 + (-15y/2).

I NEED THIS ASAP!!! The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 5 to 4. If there were 4045 yes votes, what was the total number of votes?
Answer:
The total number of votes was 7281 .
Step-by-step explanation:
Let the number of no votes be x
yes : no
5 : 4
4045 : x
4045÷5 = 809
so,
x = 4 × 809 = 3236
3236 people voted no .
Total number of votes = 4045 + 3236
= 7281 ( Ans )

Jason has 1/3 of a liter of milk. Jason divides the milk equally into 4 mugs of tea.
How much milk will Jason have in each mug?
Answer:
1/12 l
Step-by-step explanation:
Amount of milk = 1/ 3 l
No: of mugs = 4
Amount in each mug = 1/3 ÷ 4 = 1/3 x 1/4 = 1/12 l
(Hope its right!)
Answer:
They will have 1/12 of a liter of milk on each mug because you are dividing 1/3 into 4 so the denominator is multiplied by 4

Find the exact area of ABC
Answer:
A = 18[tex]\sqrt{3}[/tex] sq meters
Step-by-step explanation:
find BD, can use altitute rule:
3 / BD = BD / 9
BD² = 27
BD = [tex]\sqrt{27}[/tex] = 3[tex]\sqrt{3}[/tex]
Area of ΔABC = 1/2 · (3+9) · 3[tex]\sqrt{3}[/tex]

Solve two fifths minus one seventh equals blank.
Answer:
9/35.............,..........
Answer:
1/5
Step-by-step explanation:
2/5 - 1/7 = ???
find the least common denominator!
45 would be the least common demoninator!
so...
2 (7) / 5(7) - 1 (5) / 7 (5) = ?
14/ 45 - 5 /45 = ?
14 - 5 = 9
9/45. Simplify!
9/45 divide 9 from both sides
9/9 / 45/9
= 1/5, one fifths is your answer!

2. Nick and Adam workout together. Nick weighs
160 pounds and is gaining about 3 pounds per
week. Adam weighs 195 pounds and is los ng
about 2 pounds each week. Write an equation
that can be used to find the number of weeks
that it will take them to weigh the same amount.
a. Equation:
b. Solution:
c. How much will Nick and Adam weigh?
Answer:
Equation: 160 + 3x = 195 - 2x
Solution: 7 weeks
Step-by-step explanation:
x is going to stand for the number of weeks
Nick:
160 + 3x
Adam:
195 - 2x
Equation: 160 + 3x = 195 - 2x
Solution: 7
They would weigh 181 pounds
The equation to find when Nick and Adam will weigh the same amount is
160 + 3w = 195 - 2w
It will take 7 weeks for Nick and Adam to weigh the same amount.
After 7 weeks, Nick and Adam will both weigh 181 pounds.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
a.
Let w be the number of weeks, then the equation to find when Nick and Adam will weigh the same amount is:
160 + 3w = 195 - 2w
b.
To solve for w, we can simplify the equation:
160 + 3w = 195 - 2w
5w = 35
w = 7
c.
To find how much Nick and Adam will weigh after 7 weeks, we can plug w = 7 into either of the original equations:
Nick's weight = 160 + 3w = 160 + 3(7) = 181 pounds
Adam's weight = 195 - 2w = 195 - 2(7) = 181 pounds
Thus,
The equation to find when Nick and Adam will weigh the same amount is
160 + 3w = 195 - 2w
It will take 7 weeks for Nick and Adam to weigh the same amount.
After 7 weeks, Nick and Adam will both weigh 181 pounds.

Step-by-step explanation:

This is an arithmetic sequence.
First term = a = 2
Common difference = Second term - first term
= -3 - 2 = -5
Nth term = a + (n - 1)*d
= 2 + (n - 1)*(-5)
= 2 + n*(-5) - 1 *(-5)
= 2 - 5n + 5
= 7 - 5n
n = 19,
19th term = 7 - 5*19
= 7 - 95
= - 88
n = 21,
21st term = 7 - 5*21
= 7 - 105
= -98

Answer:
C
Step-by-step explanation:
The discriminant informs us about the nature of the zeros
• If b² - 4ac > 0 then 2 real and distinct zeros
• If b² - 4ac = 0 the 2 real and equal zeros
• If b² - 4ac < 0 then zeros are not real
The graph crosses the x- axis at 2 distinct zeros, then
b² - 4ac > 0 , that is positive → C
