A bag contains 40 red and green marbles. The ratio of red marbles to
green marbles is 3 to 1. How many green marbles are in the bag?
A. 10
B. 15
C. 20
D. 30
Answer:
39/40
Step-by-step explanation:
Since 39 out of 40 marbles are green, the probability of randomly choosing green is 39/40.
However, the probability becomes 100% when you look into the bag and choose a green marble. (Unless you are blind or unable to distinguish blue from green, in which case the probability remains 39/40.)

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the
time after launch, x in seconds, by the given equation. Using this equation, find out
the time at which the rocket will reach its max, to the nearest 100th of a second.
y = -16x2 + 168x + 92
9514 1404 393
Answer:
5.25 seconds
Step-by-step explanation:
The vertex of the parabola defined by ax²+bx+c is located at x = -b/(2a).
The time to maximum altitude is ...
x = -(168)/(2(-16)) = 168/32 = 5.25
The time at which maximum height is reached is 5.25 seconds after launch.
Twenty-four boxes of crayons weigh 235.2 ounces. How many ounces is each box of crayons? Do not include units.
Answer:

a man of mass 50 kg climbs up stairs each of height 0.2 m in 20 seconds .calculate the power of the man
Answer:
Given that ,
A man whose mass is 50kg climbs up 30 steps of a stair in 30s
each step is 20 cm high
Height at 30 steps , h=30×0.2=6 m
Change in potential energy , =mgh=50×10×6=3000 J
So, Work done by the man , W=3000 J
Power used , P=

The sum of two consecutive integers is 81. Determine the lesser of the two numbers.
Given that,
the two numbers are consecutive
The two numbers are
x and x + 1
Sum of the numbers = 81
x + (x + 1) = 81
x + x + 1 = 81
2x = 81 - 1
2x = 80
x = 80/2
x = 40
Therefore, the two numbers are x = 40 and x + 1 = 41
Find the area of the shaded figure.
Answer:
30
Step-by-step explanation:
lets see so step 1 would be to separate the shapes. to get a 3 by 6 rectangle and a triangle immediately you can figure out the area of the rectangle is 18, and from there you go to the triangle the triangle has a base measure of 6 and a height of 4 so you do 4x6 divided by 2 to get 12 so you add your two areas and you have a total area of 30
find value of x, y and z plsssss slove it
Answer:
x = 65°
y = 50°
z = 65°
Step-by-step explanation:
130° + y = 180°
y = 50°
115° + z = 180°
z = 65°
x + y + z = 180°
x + 50° + 65° = 180°
x + 115° = 180°
x = 65°

Find the slope of the line through
(-11,8),(-11, -17)
Answer:
Undefined or Infinity
Step-by-step explanation:
(x1,y1)=(-11,8)
(x2,y2)=(-11,-17)
Slope = (y2-y1)/(x2-x1)
= (-17-8)/(-11-(-11))
= -25/0
= Undefined
PLEASEE HELP.!! ILL GIVE BRAINLIEST.!! *EXTRA POINTS* DONT SKIP:((
Answer: -4
Step-by-step explanation:
Answer:
- 1/4
Step-by-step explanation:
The formula to find slope from two points is (x₂ - x₁) / (y₂ - y₁).
Substituting the points in (2, 4 = x₁, y₁ and 5, -8 = x₂, y₂) we get (5 - 2) / (-8 - 4).
= 3 / -12
= - 1/4
(Tip: when assigning the numbers to the variables, make sure x₁, y₁ are always from the same pair.)

You would just continue this pattern.
if chsd had 5 apples and 19 oranges and he sold 8 how much left
1.. YASSSS CSHD XD
2. sold 8 of which ill just assume equal?
so 1 apple and 15 orange would be left?
Kinda a weird question
Answer:
Step-by-step explanation:
he has 5 apples and 19 oranges so in total he has how many.
5+19=24 he sold 8 so you subtract that from your total 24-8=16 he has 16 left
What is the absolute value of Point B labelled on the number line? A number line with point A at coordinate negative 2.2, point B at coordinate negative 1.6, and point C at coordinate 1.2. Drag and drop the answer into the box to match the correct statement. Number Plotted at Point B a. 1/35 b. 1/15 c. -1/35 d. -1/15 PLZ HURRY
Answer:
The absolute value of Point B labeled on the number line is 1.6.
Step-by-step explanation:
Data provided in the question
In a number line
A coordinates = -2.2
B coordinates = -1.6
And, C coordinates = 1.2
Now we have to determine the absolute value of point B
Here the absolute value means the real number that contains non-negative value
So if we assume the real number be x
So,
We need to find the absolute value of Point B labelled on the number line.
[tex]\vert x \vert= \vert -x\vert = x[/tex]
[tex]\vert - 1.6 \vert = 1.6[/tex]
So, the absolute value of point B is 1.6
