if the dice is rolled 600 times, about how many 6s would you expect to get
Step-by-step explanation:
whis this is your answer
The number of times getting 6's, when the dice is rolled 600 times is 100.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Given that, the dice is rolled 600 times.
If you roll a fair, 6-sided die, there is an equal probability that the die will land on any given side. That probability is 1/6. This means that if you roll the die 600 times, each face would be expected to appear 100 times.
Therefore, number of times getting 6's, when the dice is rolled 600 times is 100.

Jeremy spent the entire weekend earning money by working around his neighborhood 15% of his total earnings was from raking leaves and $36 mowing lawns and earn the rest of his money walking dogs the end of the weekend with earning $90 how much money did he earn by walking dogs?
Answer: $40.50
Step-by-step explanation:
Since 15% of his total earnings was from raking leaves. The earning from taking leave will be:
= 15% × $90
= 0.15 × $90
= $13.50
Earnings from mowing lawns = $36
The earnings from walking dogs will be:
= $90 - $36 - $13.50
= $40.50

Katelyn was designing a cover for her binder and needed to cut some construction paper. The construction paper length can be represented by the expression (a2 + 7a - 3) if katelyn cut a piece that was (2a+5) long, how much construction paper is left
Answer:
a² + 5a - 8
Step-by-step explanation:
If the construction paper has a length of a² + 7a - 3, and Katelyn cut a piece 2a + 5 long, the amount of construction paper that would be left is,
a² + 7a - 3 - (2a + 5)
= a² + 7a - 3 - 2a - 5
collecting like terms, we have
= a² + 7a - 2a - 3 - 5
simplifying, we have
= a² + 5a - 8

How do I do this problem (similar right triangles) please explain how you did it!!
ASAP!!!
Answer:
by phythagoras theorem
(c+b)^2=(8)^2+(6)^2
(b+c)^2=64+36
(b+c)^2=100
b+c=√100
b+c=10.
by phythagoras theorem
(8)^2=(a)^2+(b)^2
64-b^2=a^2. {1}
by phythagoras theorem
(6)^2=(a)^2+(c)^2
36-c^2=a^2. {2}
In equation 1 and 2,
64-b^2=36-c^2
64-36= -c^2+b^2
28= b^2-c^2
28=(b+c)(b-c)
28=10(b-c)
b-c=28/10
b-c=2.8.
b+c=10
b-c=2.8
subtract both equations
c=3.6
option A is correct.

two parallel lines are cut by a transversal as shown below. Suppose m<8=131. Find m<1 and m<3.
Answer:
m∠1 is 49° and m∠3 is 49°
Step-by-step explanation:
In the given figure
∵ There are 2 parallel lines
∵ A transversal cuts them
∴ ∠4 and ∠8 are corresponding angles
→ Corresponding angles are equal in measures
∴ m∠4 = m∠8
∵ m∠8 = 131°
∴ m∠4 = 131°
∵ ∠1 and ∠4 formed a pair of linear angle
∵ The sum of the measures of the linear angles is 180°
∴ m∠1 + m∠4 = 180°
→ Substitute ∠4 by 131°
∴ m∠1 + 131° = 180°
→ Subtract 131 from both sides
∵ m∠1 + 131 - 131 = 180 - 131
∴ m∠1 = 49°
∵ ∠1 and ∠3 are vertically opposite angles
∴ m∠1 = m∠3
∵ m∠1 = 49°
∴ m∠3 = 49°

If a train travels 270 mi. in 9 hr., what is its average speed?
Answer:
The average speed of the train = 30 miles per hour
Step-by-step explanation:
Given
Total Distance traveled = 270 miTotal Time taken = 9 hTo determine
what is its average speed?
The average speed of the train can be calculated using the formula
Average Speed = Total Distance / Total time
= 270 / 9
= 30 miles per hour
Therefore, the average speed of the train = 30 miles per hour

write the standard form point slope form and slope intercept form of a line that passes through (-4,3) and (0,4)
Answer: See explanation
Step-by-step explanation:
Slope = 4 - 3 / 0 - (-4) = 1/4
Slope = 1/4
Point slope form: y - y₁ = m (x - x₁)
y₁ = 3
x₁ = -4
y - 3 = 1/4 ( x - [-4])
y - 3 = 1/4 (x + 4)
y - 3 = 1/4x + 1
Add 3 to both sides
y = 1/4x + 4
Standard Form: Ax + By = C
Point slope form- y = 1/4x + 4
Standard form:
y = 1/4x + 4
Subtract 1/4x from both sides
-1/4x + y = 4 or 1/4x - y = -4
Slope intercept form: y = mx + b
m = 1/4
y-intercept = 4
y = 1/4x + 4

Can you guys help we with this question.
Answer:
40
Step-by-step explanation:
(2x+1/(2x))^5 *(2x -1/(2x))^5
= ((2x)^2 -1/(2x)^2)^5 (a+b)*(a-b) =a2-b2
= (4x^2-1/4(x)^2)^5
now
x =4x^2. ,a = 1/4(x)^2 ,n =5
we have
general term = Cr *x^r *a^(n-r)
= Cr * (4x^2)^r * (1/4(x)^2)^(n-r)
= Cr *4^r * X^2r * 1/( 4^(n-r) *x^(2n-2r)
= Cr * 4^r/4^(n-r) * x^(2r)/x^(2n-2r)
= Cr * 4(2r-n) *x(4r-2n)
now for x^2
4r-2n = 2
4r -10=2
4r =12
r = 3
now for coeff
C(5,3) * 4^(2*3-5)
5!/(3!*(5-3)!) * 4
