Which expression represents the difference (6b+9) – (7b — 4)?
Answer:
there arent any options but this is what i got
− b + 13
Step-by-step explanation:
Final answer:
The difference expression (6b+9) – (7b — 4) simplifies to -b + 13 after distributing the negative sign and combining like terms.
Explanation:
The expression representing the difference (6b+9) – (7b — 4) is obtained through the subtraction of the second polynomial from the first. To perform the subtraction, one must distribute the negative sign to the terms within the second polynomial, which flips the signs of the terms inside the parentheses. Therefore, the subtraction becomes:
(6b + 9) + (-7b + 4)
Now, combine like terms:
Combine the b terms: 6b - 7b = -1b
Combine the constant terms: 9 + 4 = 13
After combining like terms, the final simplified expression is -1b + 13 or simply -b + 13.

Answer:
100 Cos 40° + 100 Sin 40° ≈ 141 yards
Step-by-step explanation:
From the diagram, side x is adjacent to the angle 40° while side y is the opposite to that same angle
This means that;
Cos 40° = x/100
x = 100 Cos 40°
Sin 40° = y/100
y = 100 Sin 40°
Therefore, total distance walked = x + y
" = 100 Cos 40° + 100 Sin 40° ≈ 141 yards
Phil collected 60 eggs and sold 44 of them to the local grocer. Phil wrote down that he sold 0.44 of the eggs he
collected. Did Phil write the decimal correctly? Explain.
Answer:
Yes
Step-by-step explanation:
Answer:
No, Phil did not write the decimal correctly. If Phil started out with 100 eggs and sold 44 then the decimal would be 0.44, but he only had 60, so the decimal would be 0.73
Step-by-step explanation:
enable to find the decimal of 2 numbers, you must divide usually the smaller number by the larger number anable to get the percentage. so, in this question, you divide 44 by 60 and therefore getting your answer, Phil sold 0.73 of his eggs.
In ΔFGH, the measure of ∠H=90° GF = 37 HG = 12 and FH = 35.
What ratio represents the sine of ∠F?
Answer:
[tex]\sin F =\dfrac{12}{37}[/tex]
Step-by-step explanation:
We are given the following in the question:
GF = 37 units
HG = 12 units
FH = 35 units
We have to find the ratio that represents sine of ∠F.
Formula:
[tex]\sin F = \dfrac{\text{Perpendicular}}{\text{Hypotenuse}}\\\\\sin F = \dfrac{HG}{GF}=\dfrac{12}{37}[/tex]
is the required ratio of sine of ∠F.
The attached image shows the triangle.
In the right triangle ΔFGH, the sine of ∠F is represented by the ratio of the opposite side (HG) to the hypotenuse (FH), so the sine of ∠F is 12/35.
Explanation:In the right triangle ΔFGH, the sine of an angle is defined as the ratio of the length of the opposite side to the length of the hypotenuse. Considering ∠F, the side opposite to it would be HG and the hypotenuse in this scenario would be FH.
Given that HG = 12 and the length of the hypotenuse FH = 35, then the sine of ∠F (sin F) would be represented by the ratio 12/35.
Therefore, the sine of ∠F in the triangle ΔFGH is 12/35.

Micah’s bicycle wheel has a radius of 14 inches. About how far will micah’s bicycle travel each time his wheel turns one full rotation?
Answer:
D. 88 inches
Step-by-step explanation:
to get the circumference of a circle the equation is C=2πr
C=87.96
Final answer:
Every time Micah's wheel turns one full rotation, the bicycle would travel approximately 88 inches.
Explanation:
The student's question relates to the travel distance of a bicycle wheel in one full rotation.
The distance traveled by a wheel in one rotation is equal to the circumference of the wheel, which is calculated by the formula:
Circumference = 2π × radius.
Given Micah's bicycle wheel has a radius of 14 inches, the calculation would be:
Circumference = 2 × π × 14 inches
Circumference = 2 × 3.1416 × 14 inches
Circumference ≈ 88 inches
Therefore, every full rotation of Micah’s 14-inch-radius bicycle wheel will result in the bicycle traveling approximately 88 inches, which is the circumference of the wheel.

Option B is the correct answer.
What is a percentage?The percentage means the required value out of 100.
It is calculated by dividing the required value by the total value and multiplying it by 100.
The percentage change is also calculated using the same method.
In percentage change, we find the difference between the values given.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Since Lilly deposited $3000 into a Roth IRA, that means she had already paid taxes on that money before depositing it.
Therefore, when she withdraws the entire $6000, she will not have to pay any taxes on the original contribution of $3000.
Now,
For the remaining $3000 (the growth), she will also not have to pay any taxes since Roth IRA withdrawals of earnings are tax-free if the account holder is over 59½ and the account has been open for at least five years.
Therefore,
Lilly will not have to pay any taxes when she withdraws the entire $6000.

how many dollars will you earn if you mow the lawn 10 times
A train station employee collects data on 160 incoming trains to the station. He notices that 18 of the 90 incoming trains on line A arrive late, and 14 of the 70 incoming trains on line B arrive late.
What is the probability that a train on line A arrives on time? What is the probability that any train arrives on time?
Answer:
Probability of a train on line A arriving on time: 80%
Probability of any train arriving on time: 96%
Step-by-step explanation:
If 18 of the 90 incoming trains on line A arrive late, we have that 90 - 18 = 72 trains of the 90 arrive on time, so the probability of a train on line A arriving on time is:
P(A) = 72/90 = 0.8 = 80%
on line B, we have that 70 - 14 = 56 trains of the 70 arrived in time, so the probability of a train from line B arriving on time is:
P(B) = 56/70 = 0.8 = 80%
To find the probability of any train arriving on time, we can use this formula:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.8 + 0.8 - 0.8*0.8
P(A or B) = 1.6 - 0.64 = 0.96 = 96%
The probability that a train on line A arrives on time is 0.8 or 80%. The probability that any train arrives on time, considering both line A and line B, is also 0.8 or 80%.
Explanation:To calculate the probability that a train on line A arrives on time, we subtract the number of trains that arrive late from the total number of trains on line A:
Probability = (Total trains on line A - Trains on line A that are late) / Total trains on line A
Probability = (90 - 18) / 90
Probability = 72 / 90
Probability = 0.8 or 80%
To calculate the probability that any train arrives on time at the station, we need to consider the total number of trains arriving on time for both lines:
Total trains on time = (Total trains on line A - Trains late on line A) + (Total trains on line B - Trains late on line B)
Total trains on time = (90 - 18) + (70 - 14) = 72 + 56 = 128
Then, we divide the number of trains on time by the total number of trains:
Probability = Total trains on time / Total trains
Probability = 128 / (90 + 70)
Probability = 128 / 160
Probability = 0.8 or 80%
