Answer:
42%
Step-by-step explanation:
figure probability of the first:
7+6+3=16
7/16=0.44
figure probability of the second:
6/15=0.40
find the average:
0.44+0.4=0.84
0.84/2=0.42
convert from decimal to fraction:
42%!
The solution is , 42% is the probability, to the nearest 10 th of a percent, that both marbles drawn will be red.
What is probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
here, we have,
given that,
A bag contains 7 red marbles, 3 blue marbles and 6 green marbles. If two marbles are drawn out of the bag.
we have,
figure probability of the first:
7+6+3=16
7/16=0.44
figure probability of the second:
6/15=0.40
find the average:
0.44+0.4=0.84
0.84/2=0.42
convert from decimal to fraction:
42%
Hence, The solution is , 42% is the probability, to the nearest 10 th of a percent, that both marbles drawn will be red.

what’s the perimeter of a rectangle with 6x+10 as it’s width and 4x+1 as it’s length
Answer:
the equation will be 2(6x+10+4x+1)
simplified to
12x+20+8x+2
simplified to
20x+22
The perimeter of the rectangle will be 20x+22
Thank you, Hope it helps
Answer: The length of both sides would be 12x+20 and the width of both sides would be 8x+2, so the perimeter of the rectangle would be 20x+22

You want to surround the perimeter of a garden with 35 stones. You need to place a certain number of large and small stones and every large stone you want to use 4 small stones. Choose the correct equation to find the number of stones for each size
Answer:
The answer is "x + 4x = 35; 7 large stones and 28 small stones"
Step-by-step explanation:
Please find the complete question in the attached file.
Let
[tex]x = \text{big stone number}\\\\y = \text{tiny stone number}\\\\x + y= 35[/tex]
Users want to use four small stones for each big stone:
[tex]Y = 4x[/tex]
solving the equations system:
[tex]x + y = 35\\\\y = 4x[/tex]
we find:
[tex]x = 7 \ \text{for big stones}\\\\y = 28\ \text{for tiny stones}\\\\[/tex]

Answer:
180
Step-by-step explanation:
Given :
the number has three digits
it is multiple of 20
hundreds digit and tens digit add to make 9
half of it is less than 100.
I suppose 180 can correctly fit into all above criterions
It is 3 digit number. 1+8 =9, 180/2 =90 which is less than 100.

I need to write an algebraic expression that includes 2 constatants, 2 variables, and 2 different operations. It also need it in word form as well as number form. NEED HELP ASAP BEEP HELP ASAP
Answer:
An example would be
(x+3)-(y+12)
The two constants are 3 and 12 (I'm assuming you meant "constant" as in the number that stands by itself and not "constatant" lol)
The two variables are x and y
The two operations are addition and subtraction
In words you could say "the quantity of x plus three minus the quantity of y plus twelve"

The middle person in a row is the 18th, how many persons are in the row?
Answer:
35
Step-by-step explanation:
You have 17 either side to make 18 the middle e.g if 2 was the middle then you have 1 either side.
Answer:
36
Step-by-step explanation:
if 18 is the middle there are 17 on each side of that person so 17+17+1=36

If the perimeter of a rectangular picture frame must be less that 200 in, and the width is 36 in. what must the height H of the frame be?
Answer:
w = width
h = height
2(w+h) < 200
w + h < 100
since w = 36, then
36 + h < 100
h < 100 - 36
h < 64
Step-by-step explanation:
The perimeter of the rectangular picture frame can be calculated by the equation,
2h + 2w = P
where h and w are height and width , respectively. Substituting the known values and the condition for the inequality,
2h + 2(36 in) < 200
The inequality gives h as,
h < 64
Thus, the answer is letter A.

What is the relationship between the corresponding angle bisectors BD and XZ?
Answer:
XZ = 2.5 BD
Step-by-step explanation:
Comparing the two triangles,
[tex]\frac{BD}{BC}[/tex] = [tex]\frac{XZ}{XY}[/tex]
[tex]\frac{6}{8}[/tex] = [tex]\frac{XZ}{20}[/tex]
⇒ XZ = [tex]\frac{20*6}{8}[/tex]
= 15
XZ = 15
So that,
BD:XZ = 6:15
= 1:2.5
Therefore, the relationship between BD and XZ is XZ = 2.5 BD.
A rectangular prism is filled with 356 cubes with an edge length of 1/4 what is the volume of this prism
Answer: volume = 5.5625 cubic units.
Step-by-step explanation:
A rectangular prism is filled with 356 cubes, then the volume of the prism will be equal to 356 times the volume of a single cube.
We know that for a cube with side length L, the volume is:
V = L^3
And we know that these small cubes have an edge length of 1/4 units.
Then the volume of each small cube is:
V = (1/4)^3 cubic units
V = (1/64) cubic units
And the volume of the prism will be 356 times that, then the volume of the prism is:
volume = 356*(1/64) cubic units
volume = 5.5625 cubic units.

Aidan took a 1020 km trip, travelling by Bus and By Train. The bus travelled at 105 km/h, and the train travelled at 160 km/h. The whole trip took 8 Hours. How Far did he travel on the train? Solve algebraically, and round your final answer to one decimal place.
Answer:
523.6 km
Step-by-step explanation:
Let x represent the distance traveled by train. Then 1020-x is the distance traveled by bus. The travel times are given by the relation ...
time = distance/speed
Then the total travel time in hours is ...
x/160 +(1020-x)/105 = 8
21x +32640 -32x = 26880 . . . . . multiply by 3360
5760 = 11x . . . . . . . . . add 11x -26880
523.6 ≈ x . . . . . . . . . . divide by 11
Aidan traveled about 523.6 km by train.

The vertex of this parabola is at (3, 5) . When the y-value is 6, the x-value is - 1 What is the coefficient of the squared term in the parabola's equation? (3, 5) A. -4 B. 4 C. 2 D.2
Answer:
The correct approach is Option A (-4).
Step-by-step explanation:
The given values are:
Vertex of the parabola,
(h, k) = (3, 5)
Passing through,
(x, y) = (-1, 6)
As we know,
The equation of parabola is:
⇒ [tex]x=a(y-k)^2+h[/tex]
On substituting the given values in the above equation, we get
⇒ [tex]-1=a(6-5)^2+3[/tex]
⇒ [tex]-1=a+3[/tex]
On substracting "3" from both sides, we get
⇒ [tex]-1-3=a+3-3[/tex]
⇒ [tex]a=-4[/tex] (coefficient of squared term)
Thus the above is the right choice.
