Answer:
-2.1
Step-by-step explanation:
2.5(x+4)=4.75
or,2.5x+10=4.75
or,2.5x=4.75-10
or,2.5x= -5.25
or,x =-5.25/2.5
or,x= -2.1
∴x=-2.1
(Ans)
Hope you find it helpful.........
Answer:
2.5(x+4)=4.75
2.5x+10=4.75
2.5x=4.75-10
2.5x=-5.25
Divide through by 2.5
2.5x÷2.5=-5.25÷2.5

Answer:
115
Step-by-step explanation:
Answer: x = 115 degrees
Step-by-step explanation:
a triangle we know all angles had up to 180 degrees
for the first triangle we have 65 + 90 = 155 then we do 180 - 155 = 25
so for the small triangle one angle is 25 degrees
now for the other triangle we have 80 + 60 = 140 then 180 - 140 = 40
so now we have all angles except x and to find that we do 25 + 40 = 65 then to find x do 180 - 65 = 115

Answer:
B: 1/6
Step-by-step explanation:
make 1/4 to 3/12. 7/12 + 3/12 is 10/12. So the green is 2/12. 2/12 simplified is 1/6.
Answer:
B
Step-by-step explanation:
7/12=53%
1/4=25%
the remaining would be 16 % ad 1/6 is 16%

PLS! ANSWER MY QUESTION..Noah will simulate the situation by putting marbles in a bag. Drawing one marble from the bag will represent the outcome of one of the batteries in the toy after 15 hours. Red marbles represent a battery that dies before 15 hours are up, and green marbles represent a battery that lasts longer. How many marbles of each color should he put in the bag?
Answer:
The number of marbles of each color that should be present in the bag is;
1 red marble and 2 green marbles
Here, we note that the probability of a battery going dead = 1/3 and the
Therefore if the red marbles represent that a battery dies before 15 hours then the probability of picking the red marble should be 1/3. That is if there is only one red marble in the bag, the probability of picking the red will be 1/3 when there are other 2 green batteries in the bag
That is there should be 1 red marble and 2 green marble in the bag.

Find the equation of the linear function
9514 1404 393
Answer:
y = -5x -1
Step-by-step explanation:
The 2-point form of the equation for a line can be useful.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (-11 -(-6))/(2 -1)(x -1) +(-6)
y = -5/1(x -1) -6 . . . . . simplify a bit
y = -5x -1 . . . . . slope-intercept form

The exact value of the given trigonometric function sin(140°)cos(20°) – cos(140°)sin(20°) is -√3/2.
What are Trigonometric functions?Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.
To find the exact value of sin(140°)cos(20°) – cos(140°)sin(20°), we can use the angle addition formula for sine:
sin(A+B) = sin(A)cos(B) + cos(A)sin(B)
We can use this formula to rewrite the expression as:
sin(140°)cos(20°) – cos(140°)sin(20°) = sin(120°+20°) - sin(120°-20°)
Then, using the angle addition formula for sine, we get:
sin(120°+20°) - sin(120°-20°) = sin(120°)cos(20°) + cos(120°)sin(20°) - sin(120°)cos(20°) + cos(120°)sin(20°)
This simplifies to:
2sin(120°)cos(20°) = 2sin(120°)cos(20°)
The value of sin(120°) is -1/2, and the value of cos(20°) is √3/2, so the final value of the expression is:
2(-1/2)(√3/2) = -√3/2
