Step-by-step explanation:
Question 1:
1foot=0.3m(2.718282)t(2.718282)r
Step 1: Divide both sides by o^2t.
fo2to2t=2.216717mrto2t
f=2.216717mro2
Answer:
f=2.216717mro2
Question 2:
1mil(2.718282)=1.6kilom(2.718282)t(2.718282)rs
Step 1: Add -11.82249iklmorst to both sides.
2.718282ilm+−11.82249iklmorst=11.82249iklmorst+−11.82249iklmorst
−11.82249iklmorst+2.718282ilm=0iklmorst
Step 2: Factor out variable i.
i(−11.82249klmorst+2.718282lm)=0iklmorst
Step 3: Divide both sides by -11.82249klmorst+2.718282lm.
i(−11.82249klmorst+2.718282lm)−11.82249klmorst+2.718282lm=0iklmorst−11.82249klmorst+2.718282l
Answer:
i=0ikorst−11.82249korst+2.718282

please simplify <3
Answer:
16y - 4
Step-by-step explanation:
4y(4y - 4) - 4(- 4 + 5 + 4y^2)
16y - 16y - 4(1 + 4y^2)
16y - 16y - 4(4y^2 + 1)
16y^2 - 16y^2 + 4

Please help it’s due tomorrow and I can’t figure this out :c
Answer:
The farmer's market apples cost $1.50 per pound.
The grocery store apples cost $1.35 per pound.
Samantha should buy her apples from the grocery store, where the apples cost $0.15 less per pound than the farmer's market apples.
Step-by-step explanation:
The graph shows that 2 pounds of apples costs $3.00, so divide the cost by 2 for the cost of a single pound:
3 ÷ 2 = 1.5
Solve for the grocery store apple cost per pound by replacing x with 1 in the given equation:
y = 1.35(1)
Then solve for y:
y = 1.35
Jeff is 4 times older than his daughter. Five years ago he was 9 times older than his daughter. Write an algebraic equation to determine the age of his daughter.
Jeff is 32, His Daughter is 8
The relationship between the age of Jeff and his daughter can be summarized by the following systems of equation:
Jeff's age = x
Jeff's Daughter's age = y
x=4y jeffs age is equal to his daughters times four
x-5=9(y-5) jeffs age minus five is equal to his daughters age minus five as well times 9
Combining these equations will get us x=32, y=8.
The algebraic equation 4D - 5 = 9D - 45. The current age of Jeff's daughter is 8 years old.
Let's represent the current age of Jeff's daughter as "D" and Jeff's current age as "J".
According to the problem:
Jeff is 4 times older than his daughter, so we can express this relationship as:
J = 4D
Five years ago, he was 9 times older than his daughter. This means that their ages five years ago are:
(J - 5) = 9(D - 5)
Now, we can write the algebraic equation to determine the age of his daughter (D):
(J - 5) = 9(D - 5)
Since we already know that J = 4D, we can substitute this into the equation:
(4D - 5) = 9(D - 5)
Now, we can solve for D, which represents the current age of Jeff's daughter. Expanding equation:
4D - 5 = 9D - 45
Next, move the variables to one side and the constants to the other side of the equation:
4D - 9D = -45 + 5
Combine like terms:
-5D = -40
Finally, solve for D:
D = -40 / -5
D = 8
Therefore, the current age of Jeff's daughter is 8 years old.

Step 1: Calculating with rational numbers in real-world contexts
In the first event, the eighth graders are running a baton relay race with three other classmates. The team’s top speed for each leg is 56.81 seconds, 59.22 seconds, 57.39 seconds, and 60.11 seconds. Use the information to predict the team’s best time for the race. (2 points)
If the team’s best time for the race is less than 4 minutes, then the eighth graders earn 40 points. If not, the seventh graders earn 40 points. Which grade should be awarded 40 points?
Each leg of the race from part a is the same distance. Calculate the team’s average time for each leg of the race. Show your work. (2 points)
If the team’s average time is less than one minute per leg, then the eighth graders earn 50 points. If not, the seventh graders earn 50 points. Which grade should be awarded 50 points?
Step 2: Using properties of operations to add and subtract with fractions
a) Jill jumped "6" "1" /"3" feet in the long-jump event. Jill’s best friend jumped "6" "5" /"7" feet. How much farther did Jill’s best friend jump? Describe in words the process you used to solve the problem. (2 points)
If Jill’s best friend jumped farther than 6.5 feet, then she beat the school record and the seventh graders earn 50 points. If not, the eighth graders earn 50 points. Which grade should be awarded 50 points?
b) Claire and her partner, Grace, are throwing for the javelin event as a team. Claire threw the javelin 42"5" /"8" feet and Grace threw it 39"3" /"5" feet. How far did the team throw the javelin? Show your work. (2 points)
If the total distance of Claire and Grace’s javelin throw is greater than 82.5 feet, then the seventh graders earns 50 points. If not, the eighth graders earn 50 points. Which grade should be awarded 50 points?
For the high jump, each competitor receives multiple opportunities to clear the bar at each height. On average, Shane completes 2 out of 3 jumps on the lowest bar, 4 out of 6 jumps on the middle bar, and 1 out of 4 jumps on the highest bar. Write an equation that you could use to find Shane’s overall average number of jumps completed. Calculate Shane’s average using the equation. (2 points)
If Shane’s average number of jumps completed is greater than one-half, then the eighth graders earn 50 points. If not, the seventh graders earn 50 points. Which grade should be awarded 50 points?

[ls answer if u know it
Answer:
Step-by-step explanation:
Answer:
1 - The sum of best times for the legs is 56.81 +59.22 +57.39 +60.11 = 233.53 seconds (3.89 minutes). Without additional information about the effects of training or the normal variation in times, this is the best prediction we can make.
2 - Since the team’s best time for the race is less than 4 minutes, the eighth graders earn 40 points.
3- 58.3825 (About 58) Average is found by adding all the data up and dividing by the amount of info there is. In this Case: 233.53 divided by 4 = 58.3825 which is around 58.
4- The seventh graders because the eighth graders got 58 which is more than 50 so the 7th grader would get the points
5- Kate’s best friend jumped 8/21 feet more than Kate did. First to find the difference between two fractions they need a common denominator, 21 works for this. Then the actual fractions need to match the denominator. 7/21 and 15/21 are our new fractions. Then when subtraction you subtract the numerators, the answer to that is 8/21 after simplifying (in this case you cant) you subtract the whole numbers, 6 – 6 = 0 the add the whole and fraction together. Kate’s best friend jumped 8/21 more feet than Kate did.
6- The seventh graders.
7- 42 5/8 + 39 3/5 Find common denominator for the fractions and rewrite them using the common denominator: 5/8 = 25/40 3/5 = 24/40 25/40 + 24/40 = 49/40 = 1 9/40 1 9/40 + 42 + 39 = 82 9/40 feet.
8- 9/40 = 0.225, plus 82 feet = 82.225 feet, this is less than 82.5, so the 8th graders earned the 50 points.
9- The equation would be the total of completed jumps divided by the total number of attempts: (2 +4 + 1) / (3 + 6 +4) = 7/13 = 0.538 average.
10- 0.538 is greater than 1/2 ( 0.50), so the 8th graders earned 50 points.
11- The race is 111.6 m long. 8 hurdles spaced 12.3 m apart means 7 spaces that are 12.3 m in length; 7*12.3 = 86.1
