Suppose y varies directly with x, and y = 8 when x = –6. What direct variation equation relates x and y? What is the value of y
Agata [3.3K]
Given:
y varies directly with x
y = 8 when x = -6

what is the value of y when x = -2?

y = kx

we need to get the constant of variation.
8 = k(-6)
8/-6 = k
4/-3 = k or - 1 1/3

y = -4/3 (-2)
y = (-4*-2) / 3
y = 8 / 3
y = 2 2/3 OR 2.67

The correct answer is Choice B. y = -1.33x ; 2.67

Tom caught 4 fish and his son caught 12 fish. The number of fish that Tom’s caught was what percent of the number of fish his so
Fofino [41]

Answer:

33.3 % (Approx) percent of fish that Tom’s caught  of the number of fish his son caught .

25% is the percent of the total amount Tom caught.

Step-by-step explanation:

Formula

Percentage = \frac{Part\ value\times 100}{Total\ values}

Part First

As given

Tom caught 4 fish and his son caught 12 fish.

Here

Part value = 4

Total value = 12

Put in the formula

Percentage = \frac{4\times 100}{12}

Percentage = \frac{400}{12}

Percentage = 33.3 % (Approx)

Therefore the 33.3 % (Approx) percent of fish that Tom’s caught  of the number of fish his son caught .

Second Part

As given

Tom caught 4 fish and his son caught 12 fish.

Total number of fish caught = 4 + 12

                                              = 16

Part value = 4

Total value = 16

Put in the formula

Percentage = \frac{4\times 100}{16}

Percentage = \frac{400}{16}

Percentage = 25%

Therefore the 25% is the percent of the total amount Tom caught.

At a pet store, one fifth of the animals are cats and three-fourth are fish. There are 40 animals at the pet store. How many are
dybincka [34]

Answer:

2 animals

Step-by-step explanation:

Number of animals=40

Fraction of fish=3/4

=>number of fish=3/4*40=30

Fraction of cats=1/5

=>number of cats=1/5*40=8

Animals which are not cats or fish are=total number of animals-(number of cats + number of fish)

Animals which are not cats or fish=40-(8+30)

Complementary, Supplementary, Vertical, and Adjacent Angles<br> 100 POINTS
shutvik [7]

Answer:

The first picture is A

The second picture is 21.8

The third picture is 20

The fourth picture is B

Step-by-step explanation:

4x + 8x = 180

12x = 180

x = 15

90 - 68.2 = 21.8

7x + 10 = 150

7x = 140

x = 20

Angle A = 63

180 - 63 = 117
