Jonathan studies for 5 hours and get to play 3 hrs.

Lucas studies for 1 hour and gets to play for 30 min =0.5 hrs

so if Lucas also studies for 5 hours he gets to play 0.5 * 5 = 2.5 hours which is less than Jonathan.

So Jonathan gets to play more

find the constant of variation k of the line y=kx through (5,8)

Use equation of line [tex]y=kx[/tex]

k is the constant of variation

LEts find out k using the point (5,8)

x=5 and y=8, plug in the values

two - point six

is the answer

The answer you are looking for is "Two and six tenths".

The reason this is, is because 2 is left of the decimal, which makes it "two". Since 6 is to right of the decimal, you have to look at how far it is from the decimal. It being directly after the decimal, it is in the tenths place, making it six tenths. Thus meaning the answer is two and six tenths.

The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of that variable would give a true mathematical statement.

We have been given a function of x that is k (x)=-7x+1. we need to find the value of the function with different values.

1. k (x)=-7x+1

When K (0)

k (x)=-7x+1

k (0)=-7 (0)+1

k (0) = 1

2. When K (-1)

k (x)=-7x+1

Substitue;

K (-1) = 7(-1) +1

K (-1) = -7 + 1

K (-1) = -6

3. when K (5)

k (x)=-7x+1

k (5)=-7(5) +1

k (5)= -35 + 1

k (5)= - 34

To solve sin (3\u03c0/4) cos (\u03c0/12), calculate the value of sin (3\u03c0/4), use the half-angle formula to find cos (\u03c0/12), and multiply the results.

To solve the expression sin (3\u03c0/4) cos (\u03c0/12), we need to find the sine and cosine values of the individual angles and then multiply them together. The sine of 3\u03c0/4 is \u221a2/2 and the cosine of \u03c0/12, which is not a standard angle on the unit circle, can be calculated using the half-angle formula since \u03c0/12 is half of \u03c0/6. Therefore, once we have both values, we simply multiply them to get the result of the expression.

If the oak tree is 48 feet tall, and is 8 times taller than Mike, you must divide 48 by 8 to find that Mike is 6 feet tall. To check your work, multiply 6 by 8 and see that you get 48 feet. Hope I helped!!

Please award brainliest!:)

Mike is 6 feet tall. This is determined by dividing the height of the oak tree, which is 48 feet, by 8, because Mike's height is said to be 1/8 of the oak tree's.

The subject of this question is a basic math problem involving division. The question states that the oak tree is 8 times as tall as Mike. So, to find Mike's height, we need to divide the oak tree's height by 8.

Applying this to the details given:
Oak Tree height = 48 feet
Mike's height = Oak Tree Height/8
Mike's height = 48/8
Mike's height = 6 feet
So, Mike is 6 feet tall.

Answer:

72 passenger planes

Step-by-step explanation:

ratio passenger to cargo = 8 to 5 = 8/5

Let p = number of passenger planes.

The ratio of passenger to cargo planes that actually landed is p/45.

The ratio in general is 8/5, so 8/5 must equal p/45.

p/45 = 8/5

5p = 45 * 8

p = 9 * 8

p = 72

Hello!

To solve for c, we will need to use SADMEP. SADMEP is strictly used to solve algebraic equations. It is an acronym for subtraction, addition, division, multiplication, exponents, and parentheses. There are some cases in which we need to divide or multiply before subtracting/adding terms, like in this problem. Our main goal is to isolate c.

3a + 4b = (1 - 2c)/d (multiply both sides by d)

d(3a + 4b) = 1 - 2c (subtract 1 from both sides)

d(3a + 4b) - 1 = 2c (divide both sides by 2)

d(3a + 4b)/2 - 1/2 = c

We can simplify still this equation.

(3ad + 4bd)2 - 1/2 = c (distribute d)

3ad/2 + 4bd/2 - 1/2 = c (divide 3ad and 4bd by 2)

3ad/2 + 2bd - 1/2 = c (simplify)

Therefore, c is equal to 3ad/2 + 2bd - 1/2.

Final answer:

c = -d(3a + 4b - 1)/2

Explanation:

To solve for c in the equation 3a+4b=1-2c/d, rearrange the terms to isolate c, multiply both sides by d to eliminate the fraction, and then divide by -2.

To solve 3a+4b=1-2c/d for c, we will isolate the variable c by following these algebraic steps:

This is how we derive the expression for c in terms of a, b, and d.

The ace pitcher was paid $14 million and the shortstop was paid $7 million.

In order to solve this problem, we can set up a system of equations. Let's say the salary of the ace pitcher is x million dollars and the salary of the shortstop is y million dollars. We are given that the ace pitcher was paid twice as much as the shortstop, so we can set up the equation x = 2y.

We also know that the total salaries paid were $21 million, so we can set up the equation

x + y = 21.

Using the first equation, we can substitute 2y for x in the second equation to get 2y + y = 21, which simplifies to 3y = 21. Dividing both sides by 3, we find that y = 7 million.

Substituting this value back into the first equation, we find that x = 2(7) = 14 million.

Therefore, the ace pitcher was paid $14 million and the shortstop was paid $7 million.

I see choice (A) is missing, so I am giving you two solutions for you to understand and decide which one applies:

(1) Final balance with compound interest - meaning every year you add the year's interest to the principal and earn interest on the increased amount, etc. This is the actual case in real banks:

principal amount is $425 at (annual) interest rate 4.5%

interest amount for 1 year $19.13

Now, use the formula for compound interest

total balance = principal*(1+interest rate)^year

[tex]\$425\cdot(1.0475)^4= \$511.68[/tex]

So the amount after 4 years with compound interest should be $511.68

(2) the silly way: earn interest of $20.1875 every year and keep it separately (not earning additional interest). That'll make 425+4*20.1875=$505.75 which is answer (C)

so if your (A) matches my solution (1) then go with that. If not, choose (C).

2 7/8 is 2.875 in decimal and then compare it to 2.75

2.875 > 2.75

therefore the answer is >(greater than)

answer:  [tex]2\frac{7}{8} < 2.75[/tex]

work: if you turn [tex]2\frac{7}{8}[/tex] into a decimal it would be [tex]2.25[/tex].

[tex]>[/tex] means greater than.

[tex]<[/tex] means less than.

so [tex]2.25[/tex] would be less than [tex]2.75[/tex] or in other words [tex]2\frac{7}{8} < 2.75[/tex] which would be your final answer.

Answer:

30 inches

Step-by-step explanation:

width = 1/4 ( 144 - 2 * 12 )

The width of the rectangle is 30 inches.

The perimeter is defined as the sum of all the sides of the figure. For a rectangle, the perimeter will be defined as the sum of all the sides of the rectangle.

Given that a rectangle has a perimeter of 144 inches. The width of the rectangle is 12 inches less than the length.

Lenght = L

Width = L - 12

The perimeter is calculated by the formula below:-

P = 144 inches

2 ( L + W ) = 144

2 ( L + L - 12 ) = 144

4L - 24 = 144

4L = 168

L = 42 inches

The width will be calculated as:-

W = L - 12

W = 42 - 12

W = 30 inches

Therefore, the width of the rectangle is 30 inches.

Estimate of product: ≈200, 50×4

The real product: 53×4=212

The product of 53 and 4, is  212.

The question is asking to estimate the product of 53 and 4, then to record the actual product of these numbers. To estimate, we could round 53 to the nearest ten, which would give us 50, and then multiply by 4:

50 x 4 = 200.

The actual product is calculated by multiplying 53 by 4:

53 x 4 = 212.

So the estimate of the product is 200 and the actual product is 212.

We are given the expression:

[tex]5(2)+2(4)^{2}-(4)^{3}[/tex]

[tex]=10+32-64[/tex]

=-22

So on plugging x=2 and y=4 in the given expression we get the value as -22

Answer : [tex]5x+2y^{2}-y^{3}[/tex]=-22

10. You are finding 3% of 100, or .03 x 100. The product should be 3.

11. You are finding the whole amount of 3, or 1 x 3. The product should be 3.

12. Again, find 80% of 120, or 0.80 x 120. The product should be 96.

13. This time, because the number is greater than 100%, you would write it as 1.15 x 6. The answer should be 6.90.

14. In this scenario you are going backwards--meaning instead of using multiplication you use division. If 32 is the amount inside of 128, you divide 32 by 128. The quotient should be 0.25, or 25%.

15. Just like #14 (except phrased differently), 3 is inside of 36, so you divide 3 by 36. The quotient should be 0.08333... or about 8%.

16. In this problem you will have to divide again, except (because the decimal is given) you divide the amount left, 23.7, by the decimal/percent, .30. The quotient should be 79.

17.  This problem is also the same as the previous, just phrased differently. 7[tex]\frac{1}{2}[/tex]%, or 7.5% is written as 0.075 in decimal form. Again, divide the amount left, 12, by the decimal/percent, 0.075. The quotient should be 160.
