Answer: 8 minutes

Step-by-step explanation:

You need to find the rate at which he peels the oranges (you need to first find out how many minutes he takes to peel per minute). To do this you need to:

- divide 20 minutes by 4 to find how many minutes he takes to peel each orange

- you will get 4 minutes per orange

- then you can multiply 4 minutes times 2 oranges which gives you 8 minutes

Therefore, it takes him 8 minutes to peel 2 oranges (assuming that he peels the oranges at a constant speed)

Answer:

2

Step-by-step explanation:

ist you have to lind the lcd of each fraction. that would be 10.

1/2x5/5=5/10 of the boys have brown eyes

1/5x2/2=2/10 of the boys have blue eyes

3/10=3/10 of the boys have hazel eyes

The question is asking to see how many more boys have brown eyes than hazel eyes.

Subtract 3/10 from 5/10

and that gives you 2/10

The answer is 1/5.

We know that half of the boys in Jason's class has brown eyes, while three-tenths of the boys in his class have hazel eyes. Therefore, if we subtract the two values, you should get your answer.

\(\frac{1}{2} -\frac{3}{10} =\frac{2}{10}\)

1/5 is the simplified version of 2/10. Therefore, 1/5 is your answer.

Answer: Seki's interest rate for the bike is 33.33% each year; Seki will owe $8250 at the end of the loan.

Step-by-step explanation:

To calculate the simple interest rate, the equation is: r = (1/t)(A/P - 1)

Where:

r - interest rate per year (in decimal format)

t -time (loan time in years)

A - total accrued amount (initial price paid + amount of interest paid)

P - principle (initial price paid)

For this scenario:

r = (1 / 30)(8250 / 7500 - 1)

   - simplify both sets of parentheses: 1 / 30 and 8250 / 7500

r = (.033333)(1.1 - 1)

   - simplify the second set of parentheses

r = (0.033333) x 0.1

   - multiply

r = 0.0033333

   - convert r (as a decimal) to R (as a percentage) by multiplying r x 100

R = .3333

The interest rate on Seki's loan is 33.33%

The total amount Seki will pay:

equation for total due: A = P + I

Where:

A - total accrued amount (initial price paid + amount of interest paid)

P - principle (initial price paid)

I - amount paid in interest that accrued over time

For this scenario:

A = 7500 + 750

A = 8250

Seki will pay $8250 when the loan is due.

Answer:

Andre should stop at (-3 , 6.5)

Step-by-step explanation:

The change in x is from -15 to 25 which is 40 units. 40 x 3/10 = 12 which means Andre moves 12 units right starting from -15 so the x coordinate is -15+12 = -3

The change in y is from 2 to 17 which is 15 units. 15 x 3/10 = 4.5 which means Andre moves 4.5 units up starting from 2 so the y coordinate is 2+4.5 = 6.5.

Answer:

the flagpole is 12 ft  

Step-by-step explanation:

2.5 ft / 4 ft = 7.5 ft / x ft

2.5x = 30

2.5x/2.5 = 30/2.5

x = 12 ft

Answer:

You = 50 mph

Friend = 30 mph

Step-by-step explanation:

You = \(\frac{250-150}{5-2}\) = \(\frac{100}{2}\) = 50

Friend = \(\frac{240-120}{8-4}\) = \(\frac{120}{4}\) = 30

Use slope formula.

Answer:

I will tell you how to do it :)

Step-by-step explanation:

ok so, an initial value of a function means that it is the y-intercept of the function, so one can also find initial values by looking for the constant of an equation now that you know the y-intercept will help in graph functions. To confirm the initial value, substitute in for x and solving for y.

Answer:

kirk is correct. it could also be represented as x= 44 - 7

Step-by-step explanation:

Answer:

A. x = -6
B. x = 15

Step-by-step explanation:

A.

\(\frac{x}{3}-5=-7\\\frac{x}{3}-\frac{15}{3}=-7\\\frac{x-15}{3}=-7\\x-15 = -7*3\\x-15=-21\\x=-21+15\\x=-6\)

B.

\(\frac{x}{2}-5=2.5\\\frac{x}{2}-\frac{10}{2} = 2.5\\\frac{x-10}{2}=2.5\\x-10= 2.5*2\\x-10=5\\x=5+10\\x=15\\\)

I hope this helps brother! :D

The circumference of a circle can be found using the formula:

C = πd

where d is the diameter of the circle and π is the mathematical constant pi (approximately equal to 3.14).

Given that the diameter of the circle is 10 m, we can substitute this value into the formula:

C = πd = π(10) ≈ 31.4

Rounding to the nearest tenth, we get a circumference of 31.4 meters. Therefore, the circumference of the circle is approximately 31.4 meters.

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

1.95 m

Step-by-step explanation:

The ratio between the parent's height and the child's height stays the same.

Therefore, 9:6 = 1.5:1.

1.5:1 = x:1.3

Hence, after calculation, the parent's height is 1.95 m.

Answer:

A letter.

You can use any letter of the alphabet, but the ones that are most commonly used are x, y, and z.

Answer:

The reflection of point S across the y-axis is point   V   . The reflection of point Q across the x-axis and the y-axis is point   V   , whose coordinates are (   -5   ,   -5.5   ).

===============================================

Explanation:

Point S is exactly 5 units away from the vertical y axis. Move from point S(5,-5.5) to the location (0,-5.5); ie move 5 units to the left. Then move another 5 units to the left to land on point V(5, -5.5)

Points V and S are the same distance away from the mirror line.

-----------------------

Reflecting point Q over the x axis lands us on point S. This time we move down 5.5 units to get to the x axis. Then move another 5.5 units to arrive at point S. As discussed above, point S then will reflect over the y axis to get to point V.

Side note: Combining two reflections produces a rotation. So effectively, going from Q to V is a rotation of 180 degrees.
