Answer: I don't know the answers for 3&4

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

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

16y - 4

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.

Answer:

Step-by-step explanation:

the answer is -1/10x+240

The function can be used to find y, the number of gallons of fuel remaining in the tank of the semi-truck after it has traveled x miles is -1/10x + 240.

The equation of a straight line can be represented by:

y = mx + c

Where m is the slope of the graph and c is the intercept on the y axis.

From the graph attached, the intercept on the y axis is 240,

therefore c = 240.

To find the slope, we use the equation:

m = change in y / change in x

m = (195 - 240) / (450 - 0)

m = -45/450

m = -1/10

by substituting the value of c and m in the equation gives:

y = mx + c

Therefore, the answer is -1/10x + 240.

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

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
