Answer: third one
Step-by-step explanation:
Answer:
3√2
Step-by-step explanation:
the 2nd answer
y=3√2
find the length of x.
Answer:
3.5
Step-by-step explanation:
so this triangle is symmetrical by AA. so x would be symmetrical to 7, and 2.5 is symmetrical to 5.
[tex]\frac{x}{2.5}[/tex] = [tex]\frac{7}{5}[/tex]
x×5=5x
2.5×7=17.5
5x=17.5
x=17.5/5
x=3.5

(2x+3x) x 3+15=12x+36
Answer:
Is this what you meant?
(2x + 3x) × (3 + 15) = 12x + 36
(5x) × (18) = 12x + 36
90x = 12x + 36
78x = 36
x = 36 / 78
x = 18 / 39
_____________________
or
3(2x+3x) + 15 = 12x + 36
10x + 15 = 12x + 36
-21 = 2x
2x = -21

It costs $46 for 8 people to go ice skating how much will it be for 11 people to go show your work please
Answer:
It will cost 63.25
Step-by-step explanation:
We can use a ratio to solve
46 dollars x dollars
--------------- = ---------------
8 people 11 people
Using cross products
46 * 11 = 8x
506 = 8x
Divide each side by 8
506/8 =8x/8
63.25 =x
It will cost 63.25
Answer:
$63.25
Step-by-step explanation:
46/8 = $5.75 each
11 x 5.75 = $63.25

Mario was shopping for a new camera. He found one with an original price of $125.00 and is marked 45% off. Sale tax for the item is 5.2%. What is the final price of the camera, including tax?
Answer:
72.33
Step-by-step explanation:
45 percent of 125 is 56.25 so you subtract that from 125 and get 68.75 and then you do 5.2 percent of 68.75 and get 3.575 which rounds to 3.58 and you add that to 68.75 and get 72.33

is x = 10 part of the solution 2x + 5 > 23? why or why not?
Answer: Yes
Step-by-step explanation: 2 x 10 = 20, then add the 5 to get 25, which is larger then 23 :)
A mechanic has two pieces of sandpaper of different sizes. Each piece is in the shape of a circle. The radius of the larger circle is 4 times the radius of the smaller circle. The area of the larger circle is how many times the area of the smaller circle?
Answer:
16 times
Step-by-step explanation:
difference in area = area of bigger circle / area of smaller circle
Area of a circle = πr²
r = radius
imagine the radius of the smaller circle = 1
Area of circle in terms of π= π
radius of the bigger circle = 4 x 1 = 4
Area of bigger circle in terms of π = π4² = 16 π
16 π / π = 16 times
A triangle is formed with side lengths of 7 inches, 24 inches, and 25 inches. Is the triangle a right triangle?
A
The triangle is a right triangle because 2(7)+2(24)=2(25) .
B
The triangle is a right triangle because 7^2+24^2=25^2 .
C
The triangle is not a right triangle because 25^2−24^2=7^2 .
D
The triangle is not a right triangle because 7^2+^25^2=24^2 .
Step-by-step explanation:
The traingle in Question B and A are right traingle because..If you use pythagoras theorem in those two questions,the sum of square of smaller two sides will be equal to the square larger side. Therefore they are rt.triangle. In D the case is opposite. As the sum of square of two smaller sides are comparatively more than larger sidei.e. hypotenuse. So it is not rt. triangle. This is your answer.
What is the equation of the line that passes through the point (4,-4) and has a
slope of -5/2
Answer:
y = -5/2x + 6
Step-by-step explanation:
y = -5/2x + b
-4 = -5/2(4) + b
-4 = -10 + b
6 = b
y = -5/2x + 6
A triangle has sides with lengths of 33 meters, 56 meters, and 65 meters. Is it a right triangle?
Answer:
Yes it is a right angled triangle.
Step-by-step explanation:
Applying the right angle rule X^2+Y^2=Z^2
33^2 + 56^2=4225
Square root=65
What is the equation of the line that passes through point Q and is parallel to line P?
Answer:
[tex]y=\frac{3}{2} x+1[/tex]
Step-by-step explanation:
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Parallel lines always have the same slope (m) and different y-intercepts (b)1) Find the slope of line P
The slope of a line is equal to the [tex]\frac{rise}{run}[/tex], or the number of units the line moves up over the number of units the line moves to the right.
We can see that for line P, for every 2 units it moves to the right, it moves up 3 units.
Therefore, the slope of line P is [tex]\frac{3}{2}[/tex].
Knowing this, the equation of a line parallel to line P would have a slope of [tex]\frac{3}{2}[/tex] as well. Plug this into [tex]y=mx+b[/tex] as m:
[tex]y=\frac{3}{2} x+b[/tex]
2) Plug the given point Q into [tex]y=\frac{3}{2} x+b[/tex] to find the y-intercept (b)
[tex]y=\frac{3}{2} x+b[/tex]
Plug in point Q (2,4)
[tex]4=\frac{3}{2} (2)+b\\4=\frac{6}{2}+b\\4=3+b[/tex]
Subtract 3 from both sides
[tex]4-3=3+b-3\\1=b[/tex]
Therefore, the y-intercept of this line (b) is 1. Plug this back into our original equation:
[tex]y=\frac{3}{2} x+b[/tex]
[tex]y=\frac{3}{2} x+1[/tex]
I hope this helps!
PLEASE HELP I HAVE TEST!! Find the measure of the arc or angle indicated
Answer:
Step-by-step explanation:
<JKL = 90 ( being inscribed angle in semi circle )
< JKP = 38 ( Inscribed angles on same arc are equal )
So now
<PKL = <JKL - < JKP
= 90 - 38
= 52
FINALLY
ARC PL = 2 * < PKL (Relation between arc and inscribed angle )
ARC PL = 2 * 52
= 104
hope it helps :)

The number above the root symbol is the amount of time you have to multiply a number by itself. When we write the square root symbol the 2 is invisible, just like the 1 with a lone variable (x=1x).
In this case it is a cube root

Ja’quan was told to go inside one afternoon while he was at summer camp. He heard thunder and saw flashes of lightning. Suddenly, small balls and chunks of ice were falling on the field. Ja’quan checked the thermometer, because he never saw ice fall in South Florida, and noticed that it was 77°F (or 25°C). How was ice able to fall even though the temperature was much warmer than freezing? a) Ja’quan read the thermometer wrong b) He must have observed hail falling from thunder clouds c) It was cold enough to allow solid precipitation to fall d) Children were most likely throwing ice Reasoning (explain your answer using science facts) _________________________________________ _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Answer:
b
Step-by-step explanation:
hail can occur at temperatures not too cold and not too hot. since he checked his thermometer and it was warm, it is certainly possible that he saw hail

Answer:
No, this is not a function. If you place the points, it will not pass the vertical line test. And, in a function, each x-coordinate has to have one y-coordinate. In this problem, there are two x-coordinates of 3, and they both have a different y-coordinate.
