7 1/6 - 62/5 = ?
O A. 45
O B. 145
O C. 1/5
O D. 1335

Answer:

7

Step-by-step explanation:

x² + 5y² + 2y = 75

2x + 10y * dy/dx + 2 dy/dx = 0

2x + (10y + 2) dy/dx = 0

x + (5y + 1) dy/dx = 0

when x = 6, y = -3

6 + (-15 + 1) dy/dx = 0

6 - 12 dy/dx = 0

dy/dx = 1/2

dy/dt = dy/dx * dx/dt = 1/2 * 14 = 7

I believe 12 inches because 1 ft is equal to 12 inches.

Answer:

x=40

Step-by-step explanation:

The angles of both expressions (4x-28) and (3x+12) are congruent (alternating exterior angles). So, you can set up the equation 4x-28 = 3x+12 because both expressions are equivalent, so it makes sense. Then solve for x.

4x - 28 = 3x + 12

x - 28 = 12

x = 40

The expected number of red candy that you will get out of 10 bags is 3 red candies.

In each bag there are 100 candies, such that there are:

All the candies have the same probability of being randomly selected, so the probability of getting a red candy is equal to the quotient between the number of red candies in each bag and the total number of candy.

P = 30/100 = 0.3

Then if you draw one candy of each bag of 10 bags, the expected number of red candies that you will have is 10 times the above probability:

N = 10*P = 10*0.3 = 3

3 red candies.

Answer:

3 x 10^4

(3rd option)

Step-by-step explanation:

8.9 divided by 3.3 is 2.69

8.9 is roughly 9

3.3 is roughly 3

9 divided 3 is 3

10^8 divided 10^4 is 10^4

when dividing numbers with exponents you subtract the exponents

so the best estimate is

3 x 10^4

Answer:

The other factor is 12⇒ A

Step-by-step explanation:

The factors of a number are all the numbers multiplied to form this number

Examples:

The factors of 12 are 1, 2, 3, 4, 6, 12 because

1 × 12 = 12

2 × 6 = 12

3 × 4 = 12

∵ The product of numbers = 1236

∵ One factor of that number is 103

∴ ------ × 103 = 1236

→ Divide the number by its factor to find the other number

∴ 1236 ÷ 103 = -------

∵ 123 ÷ 103 = 1 R 20

∵ 206 ÷ 103 = 2

∴ 1236 ÷ 103 = 12

∴ The other factor is 12

Answer:

X = 11/36

Step-by-step explanation:

First, find the common denominator of the fractions and convert them.

(4/9) x 4 = 16/36

(3/4) x 9 = 27/36

X + 16/36 = 27/36

Now you can solve for X

X = 11/36

Answer:

y = -0.05x  + 2.05

Step-by-step explanation:

y = 21/x = 21x^-1

y' = -21x^-2 = -21/x^2

At x = 21 slope = -21/(21)^2 = -0.05 to nearest hundredth.

Tangent line is y - 1 = -0.05(x - 21)

y = -0.05x + 1.05 + 1

y = -0.05x  + 2.05

To find out the box number the boxes, extract the same number of balls as the number of the box, calculate the total weight.

Considering you can only weigh the balls extracted once and you need to find the box with balls that are 1-kilo lighter; here are the steps you can follow:

The total weight using this method would be 6,300 kg which is the result of adding 30 kg (first box) + 60 kg (second box)... However, since there is a box with lighter balls the total weight will be less.

Let's imagine the weight is 6,290, this means there are 10 fewer kilos and therefore the box with the lighter balls is box 10 since this is the box number from which 10 balls were extracted.
