find the measure of the missing side
Answer:
10.3
Step-by-step explanation:
a^2 + b^2 = c^2
3.9^2 + b^2 = 11^2
b^2 = 121 - 15.21
b = 10.3
Answer:
10.3
Step-by-step explanation:
We use the pythagorean theorem. (a^2+b^2=c^2)
3.9^2 + b^2 = 11^2
3.9^2 = 15.21
11^2 = 121
15.21 + b^2 = 121
Subtract 15.21 from both sides
b^2=105.79
Take the square root of both sides
b = 10.28
10.28 is closest to 10.3 and it is also rounded to 10.3, therefore 10.3 is the answer.
Anyone know how to do this
Answer:
9 sqrt(2) /2 = PQ
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp/ hypotenuse
sin 45 = PQ = 9
9 sin 45 = PQ
9 sqrt(2) /2 = PQ
Answer:
7.7 cm
Step-by-step explanation:
You need to use trig ratios
this one needs the sin as we been to find the opposite side with the hypontenuse
9 x sin(45) = PQ = 7.65813172081
PQ = 7.7

Answer:
[tex]\$128.43[/tex]
Step-by-step explanation:
Since the cost for border paper is given in terms of feet and the dimensions of the gym are given in meters, we want to convert them to the same unit. Let's choose to convert feet to meters since that would be only one conversion:
[tex]15\:\mathrm{ft}=4.572\:\mathrm{m}[/tex]
Therefore, the cost of border paper is $6.99 pet 15 feet or $6.99 pet 4.572 meters.
Since the gym is rectangular, the gym's perimeter is equal to:
[tex]p=15+27+15+27,\\p=2(15)+2(27)=84\:\mathrm{m}[/tex]
Therefore, the cost of the total border paper for the gym is equal to:
[tex]\text{cost}=\frac{84}{4.572}\cdot 6.99\approx \boxed{\$128.43}[/tex]

The triangles at the right are similar. What is the ratio (larger to smaller ) of the perimeters ?
Answer:
The perimeters are in the same ratio as the corresponding sides.
Step-by-step explanation:
There is no diagram given in your question, so imagine an example in which the ratio of two corresponding sides is, say, 7:4 (or 7/4). Then the perimeters are in the same ratio, 7:4.
Note: The areas are in the ratio which is the square of the ratio of sides, so 49:16 in the example.

The three sides lengths of four triangles are given. Which triangle is a right triangle?
A- Triangle 2: 8,15,17
B-Triangle 3: 15, 16, 23
C- Triangle 1: 10, √65, 14
D- Triangle 4: 9, √260, 19
9514 1404 393
Answer:
A- Triangle 2: {8, 15, 17}
Step-by-step explanation:
You may recognize that the triple of choice A is a Pythagorean triple, so can be the side lengths of a right triangle.
Checking the numbers can be done nicely by a graphing calculator or spreadsheet to help avoid the tedium of doing it "by hand".
The basic idea is that the triangle will be a right triangle if the sum of the squares of the shorter sides is the square of the longer side.

The regular price of a pair of jeans is x dollars. Let f(x) = x - 15, where frepresents the price of
the jeans discounted by $15. Let g(x) = 0.8 x represent the price of the jeans discounted by 20%.
Use composition to find the price of the jeans if they are first discounted by 20%, then by $15.
Answer:
(f o g)(x) = 0.8x - 15
Step-by-step explanation:
(f o g)(x) = f(g(x)) = applying first g(x), and then using that result as input value for f(x).
so, first we discount by 20% and use g(x)
g(x) = 0.8x
and then we use that in f(x)
f(0.8x) = 0.8x - 15
and that is the result.
Please Convert 21/44
Answer:
Converted into Decimal Form : 0.47727272727
Step-by-step explanation:
To convert a fraction to a decimal you take the numerator (the number in the top of the fraction) and divide that by the denominator (the number in the bottom of the fraction.)
21 ÷ 44 = 0.47727272727
This is how you convert a fraction to a decimal. When you convert a decimal to a fraction it gets a little more complicated. Another way you could change a fraction could be by simplifying. Simplifying is when you make the fraction look more simple by decreasing the values of the numerator and denominator, dividing by the same number on both the top and bottom. If you are confused and want more detail, please comment down below.
Answer:
0.477272727........
Because 21÷44= 0.477272727..........
Kevin is 3 years older than Daniel. Two years ago, Kevin was 4 times as old as
Daniel.
Let k be Kevin's age and let d be Daniel's age.
Which system of equations renresents this situation?
Answer:
k - 2 = 4d - 8
d + 1 = 4d - 8
Step-by-step explanation:
Daniel's age = d
Kevin's age = k
Given that, k = d + 3 -------------- (1)
Two years ago, the age of Daniel = d - 2
Two years ago, the age of Kevin = k - 2
Since, two years ago, Kevin was 4 times as old as
Daniel, k - 2 = 4(d - 2)
Opening the bracket,
k - 2 = 4d - 8
Since the value of k is d + 3 (see (1))
d + 3 - 2 = 4d - 8
d + 1 = 4d - 8
(I am just giving the answer cause I LOVE Linear Equation )
1 + 8 = 4d - d
9 = 3d
9/3 = d
3 = d
Therefore, Daniel's present age is 3 and Kevin's present age = 6
Hope You understood

#CMIIWGiven m
|| n, find the value of x.
m
n
126°
(8x+6)
Answer:
6
Step-by-step explanation:
since m is parallel to n, they both also have the same angles at the intersection with the crossing line.
the total angle on one side of a line is simply a half circle = 180 degrees (the angle of flipping over from laying flat in one direction of the line to laying flat in the other direction of the line).
so, the two angles of m with the intersecting line are
126 degrees and
(8x + 6) degrees.
and their sun must be 180.
126 + (8x+6) = 180
132 + 8x = 180
8x = 48
x = 6

Answer:
answer below
Step-by-step explanation:
angles of a Tringle Addup to 180
let <2=x
61+58+x=180
x=180-61-58
x= 61°
now we know that the triangle was an isocelies triangle
<2=61°
But <2 and <4are on a straight line
therefore the sum of the angles are 180
<2+<4=180°
61°+<4=180°
<4=180°-61°
<4=119°

Answer:
f(x) +g(x) = 4x^2 +3
f(x) -g(x) = 4x^2 -6x +1
f(x)·g(x) = 12x^3 -5x^2 +3x +2
Step-by-step explanation:
Substitute for f(x) and g(x) and simplify.
(a) f(x) +g(x) = (4x^2 -3x +2) +(3x +1)
f(x) +g(x) = 4x^2 +3
__
(b) f(x) -g(x) = (4x^2 -3x +2) -(3x +1)
f(x) -g(x) = 4x^2 -6x +1
__
(c) f(x)·g(x) = (4x^2 -3x +2)(3x +1)
= (4x^2 -3x +2)(3x) +(4x^2 -3x +2)(1) . . . use the distributive property
= 12x^3 -9x^2 +6x +4x^2 -3x +2
f(x)·g(x) = 12x^3 -5x^2 +3x +2
Answer:
a.) f( x ) + g( x ) = 4 x² + 3
b.) f( x ) - g ( x ) = 4x² -6x + 3
c.)f ( x ) . g ( x ) = 12x³ - 5x² + 3x + 2
Step-by-step explanation:
Given :- f ( x) = 4x² - 3x + 2 and g(x)= 3x +1
Substitute the values of f(x) and g(x) and simplify all .
a.) f( x ) + g( x )
( 4x² - 3x + 2 ) + ( 3x + 1 )
4 x² - 3x + 2 + 3 x + 1
collect like terms
4x² - 3 x + 3 x + 2 + 1
4 x² + 3
b.) f ( x ) - g ( x )

Plss help I don't understand A circle has a diameter that extends from (2,6) to (-6,-8). What are the coordinates the
center of the circle
Answer:
(-2, -1)
Step-by-step explanation:
The centre of a circle is located at the mid-point of any diameter, hence we take the average of the coordinates of the end-points.
Cx = (2-6)/2 = -2
Cy = (6-8)/2 = -1
So the centre is located at (-2, -1)

Answer: [tex]2\sqrt{2}[/tex]
=====================================
Explanation:
Let's say we replace every copy of [tex]\sqrt{2}[/tex] with x
Doing so means we have the expression 5x-3x. That simplifies to 2x.
The last thing to do is replace the x with [tex]\sqrt{2}[/tex] and that's how we end up with [tex]2\sqrt{2}[/tex] as the final answer.
----------
In short: we subtract the numbers out front, and then tack on a root 2 at the end.
As another example, [tex]19\sqrt{2}-11\sqrt{2} = (19-11)\sqrt{2} = 8\sqrt{2}[/tex]
This is basically the same as saying 19x-11x = (19-11)x = 8x where [tex]x = \sqrt{2}[/tex]

You have to push it up the driveway into a service station. The ramp is 4 meters long and rises 0.10 meters. The car weighs 9000 N. You push with a force of 300N. How efficient is the ramp?
Answer:
Step-by-step explanation:
slope, m = 0.1m/4m = 0.025
Theoretical effort (ignoring friction) = 9000N * 0.025 = 225 N
actual effort = 300 N
efficiency
= potential energy out / actual energy in
= 225 N / 300 N = 0.75
