Help!!!! I need this due my 9:30
Answer:
D. Subtract 15 cents and add 29 cents
Step-by-step explanation:
He should subtract 15 cents and add 29 cents. This is because at 33.85 we estimated to 34 dollars which was 15 cents higher, so we must subtract by 15 to get to the exact cost. We also need to add 29 cents since we rounded down from 16.29 to 16.

Let's solve for w :
[tex] \dfrac{2w + 4}{2} = 6 - w[/tex][tex]2w + 4 = 2( 6- w)[/tex][tex]2w + 4 = 12 - 2w[/tex][tex]2 w+ 2w = 12 - 4[/tex][tex]4w = 8[/tex][tex]w = 8 \div 4[/tex][tex]w = 2[/tex]hence , value of w = 2 ~
Answer:
Choice d. w = 2 is correct
Step-by-step explanation:
[tex] \\ \frac{2w + 4}{2} = 6 - w[/tex]
[tex] \\ \mapsto2w + 4 = 2(6 - w)[/tex]
[tex] \\ \mapsto2w + 4 = 12 - 2w[/tex]
[tex] \\ \mapsto2w + 2w = 12 - 4[/tex]
[tex] \\ \mapsto4w = 8[/tex]
[tex] \\ \mapsto \: w = \frac{8}{4} [/tex]
[tex] \\ \mapsto \: w = 2[/tex]
Thus, the value of w is 2

Deon plans to ride a 15 mile bicycle trail. If his average speed is 20mi/h, which equation can he use to find the time t, in hours, for the ride?
Answer
15=20t
Step-by-step explanation:
Answer:
t = 15 / 20
Step-by-step explanation:
Given:
Distance traveled by Deon to ride a bicycle trail = 15 mile
Average speed of Deon to ride a bicycle trail = 20 mi/hour
Step-by-Step:
Let 'T' be the time taken to ride the bicycle trail.
We will use distance speed formula to write the equation to find the time 'T' in hours, for the ride.
[tex]Distance=\frac{Speed}{Time}[/tex]
Distance = 15 miles
Speed = 20 miles / hour
Time = 15 / 20
Assuming time is t, the formula would be:
t = 15 / 20
"t = 15 mi/ 20 mi/hr " will help Deon calculate the time he will take.
Therefore, t = 15 / 20
A representative from the bank speaks with you about opening a savings product. You would be guaranteed at least a 3.5% return for the next 10 years when you agree to add $25.00 each month for the entire time. Given this information and that you meet the minimum monthly contribution requirement, what would be your total accumulated value at the end of the 10 years?
Answer:
a 3.5 % return is .035/12 - .002917 / mo
10 years is 120 mos.
This is basically an annuity payment - after 10 years 1$, deposited monthly, would be worth (similar to house mortgage, etc.)
N = (1 - (1 + i)^-120) / i = 241.73
Total amount = 25 * 241.73 = 6043
Note 120 payments at $25 = 3000

Step-by-step explanation:
identify the solutions of the inequality 5 ≤ s − 6
Answer:
s≥11
Step-by-step explanation:
5 ≤ s -6
=5 + 6 ≤ s
=11 ≤ s or s≥11
The solution to given inequality 5 ≤ s − 6 for s will be s ≥ 11.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
Inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
Given the inequality,
5 ≤ s − 6
Subtracting by 5 on both sides,
5 - 5 ≤ s - 6 - 5
0 ≤ s - 11
Adding 11 on both sides
0 + 11 ≤ s - 11 + 11
11 ≤ s or s ≥ 11
Hence "The solution to given inequality 5 ≤ s − 6 for s will be s ≥ 11".

explain why 120% cannot be the probability of some event?
Answer:
A probability must be between zero and one.
Step-by-step explanation:
Probability is the chance of something occuring. 120% is not realistic in real world examples, because the probability standard ranges from "definitely will not happen" to "definitely will happen", meaning a 0% chance of it occurring to 100% chance of it occurring. The only time 100.0%+ will be applicable are typically in simulations, which allows for such to counterbalance any negatives percentages that is allocated to the target. However, in the real world, it will never go over 100%.

In warmer climates, approximate temperature predictions can be made by counting the number of chirps of a cricket during a minute. The Fahrenheit temperature
decreased by forty is equivalent to one-third of the number of cricket chirps.
(a) Write an equation for this relationship.
(b) Approximately how many chirps per minute should be recorded if the temperature is 90°F?
(c) If a person recorded 72 cricket chirps in a minute, what would be the Fahrenheit temperature according to this formula?
(a) Let F represent the Fahreheit temperature and let x represent the number of chirps. The equation for this relationship is
(Use integers or fractions for any numbers in the expression.)
The relationship between temperature and the number of chirps based on the information given goes thus :
150 chips 64°F[tex] f - 40 = \frac{x}{3}[/tex]Let :
Temperature = f ; number of cricket chirps = n[tex] f - 40 = \frac{n}{3}[/tex]1.) Chirps per minute if temperature is 90°F
Put f = 40°F into the equation :
[tex] 90 - 40 = \frac{n}{3}[/tex]
[tex] 50 = \frac{n}{3}[/tex]
[tex] n = 50 \times 3 = 150 chirps [/tex]
2.) Fahrenheit temperature if n = 72
[tex] f - 40 = \frac{72}{3}[/tex]
Cross multiply
[tex] 3(f - 40) = 72[/tex]
[tex] 3f - 120 = 72[/tex]
[tex] 3f = 72 + 120 [/tex]
[tex] 3f = 192[/tex]
[tex] f = \frac{192}{3} = 64 [/tex]
3.)
The equation for the relationship with f = Fahrenheit temperature and x = number of chirps
[tex] f - 40 = \frac{x}{3}[/tex]

what is Sample space?A sample space is a set of potential results from a random experiment. The letter "S" is used to denote the sample space. Events are the subset of possible experiment results. Depending on the experiment, a sample area could contain a variety of results.
Given:
The sample space for rolling two 6-sided dice, there are 36 possible outcomes
(1,1),(1,2),(1,3),(1,4),(1,5),(1,6)
(2,1),(2,2),(2,3),(2,4),(2,5),(2,6)
(3,1),(3,2),(3,3),(3,4),(3,5),(3,6)
(4,1),(4,2),(4,3),(4,4),(4,5),(4,6)
(5,1),(5,2),(5,3),(5,4),(5,5),(5,6)
(6,1),(6,2),(6,3),(6,4),(6,5),(6,6)
The possibility of getting sum of three is (1,2) and (2,1)
and, The possibility of getting sum of ten is (4,6), (5,5), and (6,4)
Thus, the expected winning on a role is
= (2/36) x 20 + (3/36) x 10
= $1.94
If the gambler paid $5 which means
= -$5 +$1.94
= -3.06
Hence, The gambler can expect to lose $3.06 per play on average.
