Answer:
1 ÷ 6
Step-by-step explanation:
Let us assume the probability of the red marble for selecting it first time be x
And, it is to be done 3 times
that means
= 1 ÷ x × 1 ÷ x × 1 ÷ x
This equivalent to = 1 ÷ 216
And the 216 could be calculated by multiplied 6 3 times i.e.
= 6 × 6 × 6
= 216
So, the probability for selecting it for a first time is
= 1 ÷ 6
Solve for b. Show your work (ALL steps must be shown): 4b-3b+7=10 *
Answer:
the answer should be 3 100% sure
Step-by-step explanation:
Simplify 4b-3b+74b−3b+7 to b+7b+7.
b+7=10b+7=10
2 Subtract 77 from both sides.
b=10-7b=10−7
3 Simplify 10-710−7 to 33.
b=3b=3

Answer:
The first one.
Step-by-step explanation:
I believe the correct answer is the first one on the list because the variable, R, is 6 ticks below 0. How I got that was by going to 0 and counting down 6 lines and thats where R was located.
Answer:
Second
Step-by-step explanation:
Because, according to the question we are searching for the opposite of R. So, a distance of 6 and marks above 0 represent the positive side, so the opposite.
Algebra i P.1 Identify arithmetic and geometric sequences X76 You have prizes to re Farmer Hanson has a plot of tomato plants. There are 2 tomato plants in the first row, 8 tomato plants in the second row, 32 tomato plants in the third row, and 128 tomato plants in the fourth row. What kind of sequence is this? arithmetic geometric both neither Submit
===============================================
Explanation:
The sequence 2,8,32,128,... is geometric
To get a new term, we multiply by the common ratio 4.
2*4 = 8
8*4 = 32
32*4 = 128
To find the common ratio, you pick any term you want, and divide by its previous term
r = (term2)/(term1) = 8/2 = 4
r = (term3)/(term2) = 32/8 = 4
r = (term4)/(term3) = 128/32 = 4
The starting term is a = 2, so the nth term is
a(n) = a*(r)^(n-1)
a(n) = 2*(4)^(n-1)

What is the interest rate if...
Principal = $1,250
Time = 4 years
Interest = $285.
Answer:
The answer is 5.7 %Step-by-step explanation:
To find the rate given the principal , time and interest , we use the formula
[tex]r = \frac{100I}{pt} \\ [/tex]
where
p is the principal
t is the time
I is the interest
From the question
Principal = $1,250
Time = 4 years
Interest = $285
We have
[tex]r = \frac{285 \times 100}{4 \times 1250} = \frac{28500}{5000} = \frac{285}{50} \\ = 5.7[/tex]
We have the final answer as

There are 100 seniors and 80 juniors in the homecoming parade. The students split up into groups of even size, to fit on the parade floats. They want the most students possible on each float, with just juniors or just seniors on each float. How many students should be on each float?
Answer:
20
Step-by-step explanation:
Number of juniors = 80
Number of seniors = 100
To obtain the same and highest number of student on each float ; we find the highest common factor :
____80 ___100
_2__40___50
_2__20___25
_5__ 4____5
The highest common factor = (2 * 2 * 5) = 20

This is the same as 9pi/2 or (9/2)pi
===================================================
Explanation:
A full circle has area
A = pi*r^2
Since the radius is r = 3, we know that
A = pi*r^2
A = pi*3^2
A = pi*9
A = 9pi
is the area of the full circle with radius 3.
But we have a semicircle here, so we need to cut this area in half
9pi/2 = (9/2)pi = 4.5pi
Answer:
9pi
Step-by-step explanation:
A=pi r ^2 / 2
Sofia wants to rent an apartment. She visits Apartment A which charges $100 for a one-time deposit and $400 per month for rent. She also visits Apartment B which charges $500 for a deposit, but only charges $350 per month in rent. Write and solve an inequality that shows how many months it would take for the total paid to be less for Apartment B.
Answer:
It takes 9 or more months for the Apartment B to pay less than Apartment A.
Step-by-step explanation:
Apartment B:
8 x 350 = $2800
$2800 + $500 = $3300
----------------------------------------------
9 x 350 = $3150
$3150 + $500 = $3650
Apartment A:
$400 x 8 = $3200
$3200 + $100 = $3300
----------------------------------------------
9 x 400 = 3600
3600 + 100 = 3700
Solve |-21 + 5|
What is the answer of this expression?
Answer:
|-21 + 5| = 16
Answer:
16
Step-by-step explanation:
The absolute value function always gives a positive value, that is
| - a | = | a | = a , thus

Answer:
every number you can think of
Step-by-step explanation:
6x - 3y = -6
=> 3(2x - y) = -6
=> 2x - y = -2
And you see there's a problem here. The question doesn't have enough information because x and y can be every numbers.
Take an example, x can be 200 and y can be 402 or x can be 5 and y can be 12.

PLEASEEEE ANSWER! Jasmins dog weighs 58 pounds.Hef vet told her that a healthy weight for her dog would be less than or equal to 47 pounds. Jasmins dog can lose an average of 4.5 pounds every week. Write the solution to an inequality that describes all possible number of weeks for which her dog can be at a healthy weight
Answer:
w ≥ 3
Step-by-step explanation:
Weight of dog = 58pounds
Healthy weight ≤ 47
Average weight loss = 4.5 pounds per week
Write the solution to an inequality that describes all possible number of weeks for which her dog can be at a healthy weight
Minimum Weight loss required to be a healthy dog :
(58 - 47) pounds = 11 pounds
Weight loss per week = 4.5 pounds
Possible number of weeks for which dog can be a healthy dog :
Number of weeks ≥ (11 / 4.5)
Number of weeks(w) ≥ 2.44
Hence, number of weeks(w) ;
w ≥ 3

state the slope of a line parallel to the given line y-5 = 4 ( x+3)
Answer:
slope = 4
Step-by-step explanation:
Parallel lines have equal slopes.
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 5 = 4(x + 3) ← is in point- slope form
with slope m = 4
A parallel line has a slope of 4
