Answer:
P(green) = 1/5
Step-by-step explanation:
P(yellow or blue on board 1) = 2/4 or 1/2
P(yellow or blue on board 2) = 2/5
2/5*2/4 = 4/20
Simplify.
1/5
0.6(2n-9) = 3.4-2 (3n-1)
solve the following equation only
Answer:
n=1.5
Step-by-step explanation:
distribute: 1.2n-5.4= 3.4-2(3n-1)
Add numbers]: 1.2 n - 5.4= 5.4-6n
Move terms: 1.2n+6n- 5.4=5.4
Add like terms: 7.2n= 5.4+5.4
Divide both sides of equation by 7.2
Answer n= 1.5
please help ASAP!!
Let ∠1, ∠2, and ∠3 have the following relationships.
what is the equation of the line that goes througtthe points (4,-1) and (2,3)?
Answer:
y = -2x + 7
Step-by-step explanation:
Answer:
Step-by-step explanation:
recall the two formulas
y = mx - b slope-intercept
y - y1 = m(x-x1) point-slope
with these we can get the equation . we also need to find the slope m
m = y2-y1 / x2-x1
m = 3 - (-1) / 2-4
m = 3 + 1 / -2
m = 4 / -2
m = -2
now with the slope known, plug in either point into the point-slope formula and work to the slope-intercept formula, I'll use (2,3) as the point to plug in.
y - 3 = -2(x-2)
y - 3 = -2x +4
y = -2x + 7
there.. that's your answer
y = -2x + 7

Answer:
9r^4−r^3s−8r^2s^2+5rs^3+37
Step-by-step explanation:
Distribute the Negative Sign:
=29r4−11r3s+5r2s2+19rs3+4+−1(20r4−10r3s+13r2s2+14rs3−33)
=29r4+−11r3s+5r2s2+19rs3+4+−1(20r4)+−1(−10r3s)+−1(13r2s2)+−1(14rs3)+(−1)(−33)
=29r4+−11r3s+5r2s2+19rs3+4+−20r4+10r3s+−13r2s2+−14rs3+33
Combine Like Terms:
=29r4+−11r3s+5r2s2+19rs3+4+−20r4+10r3s+−13r2s2+−14rs3+33
=(29r4+−20r4)+(−11r3s+10r3s)+(5r2s2+−13r2s2)+(19rs3+−14rs3)+(4+33)
=9r4+−r3s+−8r2s2+5rs3+37

Answer:
31.243 units
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationships between sides and angles in a right triangle. Using the attached figure, it is convenient to find the length of BE as an intermediate step in the solution.
Sin = Opposite/Hypotenuse
sin(30°) = BE/100
BE = 100·sin(30°)
Then ...
Tan = Opposite/Adjacent
tan(58°) = BE/x
x = BE/tan(58°) = 100·sin(30°)/tan(58°)
x ≈ 31.243 . . . . units
_____
Comment on the figure
The intermediate problem in creating the figure was to locate point D. That was accomplished by locating point C on a line at an angle of 58° CCW from the horizontal, using point B as a center. Then D is the intersection of BC with the x-axis. BE is drawn perpendicular to the x-axis.
Two friends leave school at the same time, Sarah is heading due north and Beth is heading due east. One hour later they are
5 miles apart. If Sarah had traveled 4 miles from the school, how many miles had Beth traveled?
OA. 2 miles
ОВ.
1 mile
OC. 3 miles
Answer:
Step-by-step explanation:
If you picture this scene in your head, you will get a simple 3x4x5 right triangle. 4 times 2 is 8, 5 times 2 is 10, so Sarah should, by now, have traveled 3 times 2 miles.
Final answer: Sarah has traveled 6 miles after an hour.
Hope this helped! :)
Helping tip: The reason it is not 4 is because they are not traveling west and east away from each other. They are traveling north and east, so they are moving in two directions to form a right triangle, and the hypotenuse would be 10 (miles). The side, or distance, that Beth has traveled is 8. So as this is a typical variation of a 3x4x5 triangle, Sarah will have traveled 6 miles.

The answers are 3 and -13
You need to plug 3 and -5 into x
By doing this, you get :
12 - 3^2 and
12 - (-5)^2
those expressions equal
12 - 9
12 - 25
So you get

She square was 10 ft by 10 ft. Suppose uses the same amount of fencing to enclose a circular area. What is the area of the circle? Use 3.14 for .
Answer:
127.41ft^2
Step-by-step explanation:
Given data
DImension of the square
10ft by 10ft
The perimeter of the square is
=10+10+10+10
=40ft
Hence the amount of the fencing of the circle is 40ft
That is the circumference is 40ft
C=2πr
solve for r
40=2*3.14*r
40=6.28r
r= 40/6.28
r=6.37 ft
Area= πr^2
Area= 3.14*6.37^2
Area= 3.14*40.5769
Area= 127.41ft^2

Use the Triangle Inequality Property to determine whether a triangle can be formed with the given side lengths. 4 m, 8 m, 9 m *
Answer:
Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene, isosceles, equilateral and so on.
The triangle inequality property states that the sum of any two sides of a triangle must be greater than the third side. If a, b and c are the sides of a triangle then:
a + b > c; a + c > b; b + c > a
Given a triangle with side length 4 m, 8 m, 9 m:
4m + 8m = 12m > 9m
4m + 9m = 13m > 8m
8m + 9m = 17m > 4m
Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m.

7 ( 2x - 3 ) = 7
Show work and you will get Brainliest
Answer:
x=2
Step-by-step explanation:
Distribute the 7 across the 2x and 3:
[tex](7)(2x)-3(7)=7[/tex]
[tex]14x-21=7[/tex]
Isolate the x term by adding 21 on both sides:
[tex]14x=28[/tex]
Isolate x by dividing by 14 on both sides:
[tex]\frac{14x}{14}=\frac{28}{14}[/tex]
[tex]x=2[/tex]
If this helped, brainliest answer would be greatly appreciated!

select all the statements that are true about the equation y=-2/3x+5
Answer:
The slope of the line is negative. The y-intercept is 5. The slope of the line is -2/3.
Step-by-step explanation:
With 2 given points on the line that are whole numbers, you can find the slope of the line with the equation [tex]m=\frac{y2-x2}{y1-x1}[/tex]. The answer will tell you whether it's negative or positive. For example, [tex]m=\frac{-2-1}{4-0} =\frac{-3}{4}[/tex]. The slope is negative for the example. The y-intercept would be the point with 0 as the x-value: (0, -5).
