8 blue marbles, 24 red marbles, 16 green marbles, 4 yellow marbles.
~
1) 8/100
2) 2/13
3) 6/13
4) 4/13
Step-by-step explanation:
Total marbles = 24 + 8 + 16 + 4 = 52
Probability of blue marble = 8/ 52 = 4 / 26 = 2 / 13
Option 2 is the correct answer
what is the factor of -12n - 20 ( 50pts!!!!!)
Answer:
-4(3n + 5)
Step-by-step explanation:
We want to factor the expression:
-12n - 20
Look at the two terms, which are -12n and -20. Obviously, they don't share an "n", but they do share another number.
Notice that -12 can be written as the product of -4 and 3: -12 = -4 * 3. Similarly, -20 can be written as the product of -4 and 5: -20 = -4 * 5. Since 3 and 5 are prime numbers, we know that -4 is the biggest factor that -12 and -20 share. So, let's factor that out of the expression:
-12n - 20 = -4 * [(-12n/-4) + (-20/-4)] = -4 * (3n + 5)
So, the factored form of this expression is -4(3n + 5).
Steps to factor:
-12n - 20
~Rewrite -12n
-4 * 3n
~Rewrite -20
-4 * 5
~Put together
-4 * 3n + -4 * 5
~Factor out -4
-4(3n + 5)

Jessi has 9 feet of blue fabric. She need one third of that amount in red fabric. The fabric store sells fabric by the yard. How much fabric does Jessie need to buy?
Answer:
1 yard
Step-by-step explanation:
Let b represent the amount of blue fabric and r represent the amount of red fabric.
Given;
Jessi has 9 feet of blue fabric
b = 9 ft
She need one third of that amount in red fabric.
r = 1/3 × b
Substituting the value of b;
The amount of red fabric needed r is;
r = 1/3 × 9 = 3 ft
Since they sell in yards , we need to convert it to yards.
1 yard = 3 feets
Therefore,
r = 3 ft × 1/3 yard per ft
r = 1 yard

Find the interval of convergence for:
Please note: The 2 in the picture must actually also be an exponent, so n^2^n.
Answer:
-∞ < x < ∞
Step-by-step explanation:
∑ xⁿ / n^(2ⁿ)
Apply ratio test:
lim(n→∞) | [xⁿ⁺¹ / (n+1)^(2ⁿ⁺¹)] / [xⁿ / n^(2ⁿ)] |
lim(n→∞) | [xⁿ⁺¹ / (n+1)^(2ⁿ⁺¹)] × [n^(2ⁿ) / xⁿ] |
lim(n→∞) | x n^(2ⁿ) / (n+1)^(2ⁿ⁺¹) |
0
The series converges for all values of x.

A Wallace's giant bee is 1 1/2 inches long. If this bee is four times longer than a worker bee, how
long is the worker bee?
3/8 in.
1/3 in.
1/8 in.
3/10 in.
Answer:
3/8 in.
Step-by-step explanation:
If the giant bee is four times longer than a worker bee, you'd divide the giant bee's length by 4 to get the worker bee's length. 1.5 ÷4=0.375. 0.375 is equivalent to 3/8. So 3/8 in.
s= ut + 1/2 at x2
u=10
a=-2
t=1/2
work out the value of s
Answer:
s = 4 3/4.
Step-by-step explanation:
The formula is s = ut + 1/2 at^2
so s = 10^1/2 + 1/2 * -2 * (1/2)^2
s = 5 - 1/4
= 4 3/4.
In a quadrilateral, the measure of two opposite angles is the same. Each of the other
two angles measures exactly two times the given angle. Find the measure of each angle
in the quadrilateral.
Answer:
the two opposite angles equal 45 and the other two who are twice the amount is 90
Step-by-step explanation:
sum of angles in a quadrilateral is 360. Lets name the two equal diagonal angles x that means the equation wil be
x+x+2x+2x=360
8x=360
x=45
so the equal diagonal ones will be 45 and the other two angles will be twice as much so 45x2=90

Find the value of x. (Circles)
Answer:
x =64.5
Step-by-step explanation:
Inscribed Angle = 1/2 Intercepted Arc
The total circle is 360 degrees
The arc is 360 - 113 - 118
arc =129
x = 1/2 (129)
x =64.5
Answer:
64.5°
Step-by-step explanation:
Using the inscribed angle theorem here would help to find the value of x°.
The inscribed angle theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.
First find the arc PM. Write an equation to show that the measures of the following arcs: PQ, QM, and PM add up to 360°, since they span an entire circle. Then solve for the arc PM.
mPM + mPQ + mQM = 360°
mPM + 113° + 118° = 360°
mPM + 231 = 360°
mPM = 129°
Now, find m<Q. <Q is an inscribed angle that intercepts the arc PM, so use the Inscribed Angle Theorem.
m<Q = 1/2 * mHJ
= 1/2 ( 129 )
= 64.5°
X = 64.5 degrees.

Scarlett bought 9 chicken wings for $3. What was the cost of the wings in wings per dollar? Express your answer in simplest form.
Answer:
3
Step-by-step explanation:
To find how much you can get for one dollar, you have to divide 9 by 3. If you have to find how many units can you get for one dollar, (you need to divide the larger number by the smaller)
Divide 9 by 3.
9/3=3
So, with $1, you can get 3 chicken wings.
Find the volume of the cone khan academy
Answer:
V= 1/3 pi*r^2*
Step-by-step explanation:
The reason the volume of a cone involves using the fraction 1/3, is because it takes three cones to fill up a cylinder. So, if the volume of a cylinder is pi*r^2*h, and a cone is 1/3 the size, then the volume of a cone(which uses the same formula) has to have the 1/3rd in front.
