Answer:
cos(θ) = (5√74)/74
Step-by-step explanation:
The length of the hypotenuse is given by the Pythagorean theorem:
h = √(5² +7²) = √74
The cosine of the angle is the ratio of the adjacent leg to the hypotenuse:
cos(θ) = 5/√74 = (5√74)/74
A sprinkler system uses 800 gallons of water in 5 days. The system uses ___ gallons of water in 1 day
Answer:
160
Step-by-step explanation:
800 gallons in 5 days. The days is the denominator and the gallons are the numerator, whatever you do the the bottom you do to the top, so you divide the denominator by 5 and the numerator by 5 and you get 160 gallons per day. If you want to know how your answer is right, multiply 160 by 5

[tex]\sqrt{2n^{2}}[/tex]
You have the side lengths of the two legs, n and n.
Then, using the pythagorean theorem you have to find the length of the third side:
[tex]a^2 + b^2 = c^2\\n^2 + n^2 = c^2\\2n^2 = c ^ 2\\\sqrt{2n^2} = c[/tex]
where c is the third side
Jenny bought scrapbooking supplies for $145.00. She paid $11.60 in sales tax. What was the sales tax rate on the supplies? If necessary, round your answer to the nearest tenth.
a) 7%
b) 8%
c) 9%
d) 7.5%
The sales tax rate is 8%.
The correct option is (b).
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Jenny bought scrapbooking supplies for $145.00.
She paid $11.60 in sales tax.
let the tax rate be x%.
So, the price without sales tax = 145 - 11.6 = $133.4
Thus, x% of 133.4 = 11.6
133.4 x = 1160
x = 8.65%
x= 8%
Hence, the tax rate is 8%.

Answer:
-6x+7
Step-by-step explanation:
Start by multiplying (x-1) by -4 and (x+1) by -2.
Then you will have the equation 5-4x+4-2x-2
Next, just find your like-terms.
Your like-terms are 5,4,-2 and -4x, 2x
Then, for easier for calculation, just use the equation:

Answer:
a, b, e (only)
Step-by-step explanation:
The circle centered at A is all of the points that are distance AB from A.
The circle centered at B is all of the points that are distance AB from B.
The points C and D are points that are distance AB from both A and B.
The line joining those points (C and D) consists entirely of points that are equal distances from A and from B. CD is the perpendicular bisector of AB.
Point M is one of the points on line CD, and is also on segment AB. Because it is on CD, we know it is the same distance from A as from B. That means AM = BM, and M is the midpoint of AB.
__
Points B, C, D are not on the same line, so can form a triangle. As with any triangle, the sum of any two segments is greater than the length of the third. Here, this is expressed as CB + BD > CD.
__
With some work using the Pythagorean theorem, you can show that ...
CM = AM×√3
Similarly, MD = BM×√3.
Adding these two relations tells us ...
CM +MD = √3(AM +BM)
CD = AB×√3 . . . . . AB and CD are not the same length
__
AM and BM are on the same line, so cannot be perpendicular to each other.

What is the solution to the system of equations2x + 3y = 40andy=x + 10?
A
x = 2; y = 12
B
x = 4; y = 14
C x = 12; y = 2
D x = 14; y = 4
Answer:
A is the correct answer
Step-by-step explanation:
If you plug y=x+10 in for the Y variable you just have to solve by multiplying.
1.) It should look like this:
2x + 3(x +10) = 40
2.) You will distribute the three which will make the equation look like this:
2x + 3x + 30 = 40
3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.
Hope that helps

Step-by-step explanation:
[tex](3x - 2) = \frac{(2x-1)}{2}[/tex]
2(3x - 2) = (2x - 1)
6x - 4 = 2x -1
4x = 3
x= 3/4
Answer:
x=3/4
Step-by-step explanation:
Remove parentheses.
3x-2=\frac{2x-1}{2}3x−2=22x−1
Multiply both sides by 22.
6x-4=2x-16x−4=2x−1
Add 44 to both sides.
6x=2x-1+46x=2x−1+4
Simplify 2x-1+42x−1+4 to 2x+32x+3.
6x=2x+36x=2x+3
Subtract 2x2x from both sides.
6x-2x=36x−2x=3
Simplify 6x-2x6x−2x to 4x4x.
4x=34x=3
Divide both sides by 44.
x=\frac{3}{4}x=43

sales tax is added.
What is the total after markup and tax?

The perimeter of a rectangular pool is 72 meters. If the length of the pool is twice its breadth. Its length is_________.
Answer:
Length = 18 meters
Step-by-step explanation:
Let the length of the rectangular pool = l meters
And breadth of the pool = w meters
Perimeter of the rectangular pool = 2(l + 2w)
Since, perimeter of the rectangular pool is 72 meters.
2(l + 2w) = 72
l + 2w = 36 --------(1)
If length of the pool is twice of its breadth,
l = 2w
w = [tex]\frac{l}{2}[/tex] -------(2)
By substituting the value of 'w' from equation (2) to equation (1),
[tex]l+2\times{\frac{l}{2}}=36[/tex]
2l = 36
l = 18 meters
