Answer:

The jumping dolphin --  changes

The flying seagull -- same

The octopus --  same

Step-by-step explanation:

The distance of the Albatross from the sea surface when compared to the vertical distance from the eyes of the :

The jumping dolphin :

As the dolphin jumps out from the sea, the vertical distance of the albatross from the surface seems to be decreasing and then increasing as seen by the jumping dolphin.

The flying seagull :

The distance of the albatross is at the same height as seen by the seagull since it is flying at the same level, i.e. at the level of the sea surface

The octopus :

The octopus remains at the same depth below the water surface. So the distance of the albatross for the octopus remains the same at 5 m above the ocean surface.

Answer:

x = 33

Step-by-step explanation:

Sum of the angles in a triangle is 180 so,

35 + 3x + 2x - 20 = 180

35 + 5x - 20 = 180

15 + 5x = 180

5x = 180 - 15

x = 165/5

x = 33

Answer:

12/35

please give me brainliest!

The product of the fractions is 12/35, or 2/5 x 6/7 as a fraction is equal to 12/35.

Given that we need to convert 2/5 x 6/7 in a fraction.

To multiply fractions, you simply multiply the numerators (top numbers) together and the denominators (bottom numbers) together. In this case, you have:

(2/5) x (6/7)

Multiplying the numerators gives you 2 x 6 = 12, and multiplying the denominators gives you 5 x 7 = 35.

So, the product of the two fractions is: 12/35

Therefore, 2/5 x 6/7 simplifies to 12/35 as a fraction.

Answer:

v= 25

Step-by-step explanation:

Try to isolate the variable by getting rid of the 5. Multiply both sides of the equation by 5 to cancel out the 5 on the left side. You are left with 7v= 35(5). Simplified it is 7v= 175. Then to get the v alone, you need to divide both sides by 7 to cancel out the 7 on the left side. You are left with v= 175/7.

This is v= 25

Answer:

50

Step-by-step explanation:

Wen: 30% of the total number of cards = 60 cards

Set this up as an equation

30/100 = 60/x

Cross multiply

30 × x = 100 × 60

30x = 6000

Divide both sides by 30 to isolate the variable

x = 200

There are 200 cards total

Gina: 25% of the total 200 cards

Set this up as an equation

25/100 = x/200

Cross multiply

25 × 200 = 100 × x

5000 = 100x

Divide both sides by 100 to isolate the variable

50 = x

Gina's share is 50 cards

Answer:

3 minutes; 27 minutes; 30 minutes

Step-by-step explanation:

Let the common multiplier of the given ratios be x. So, the ratios 1: 9 : 10 will become x, 9x and 10x respectively.

Therefore,

[tex]x + 9x + 10x = 1 \: hour \\ \\ 20x = 60 \: minutes \\ \\ x = \frac{60 \: minutes}{3} \\ \\ x = 3 \: minutes \\ \\ 9x = 9 \times 3 = 27 \: minutes \\ \\ 10x = 10 \times 3 = 30 \: minutes[/tex]

Thus, 1 hour in the ratio 1 : 9 : 10 can be divided as:

3 minutes; 27 minutes; 30 minutes

Answer:

13.8 ounces of salt

Step-by-step explanation:

A restaurant small salt shakers contains 0.6 ounces of salt. The shakers are filled from a container that has 18.6 ounces of salt. If 8 shakers are filled, how much salt will be remaining in the salt container?

Step 1

Note that:

1 shaker = 0.6 ounces of salt

8 shakers = x

Cross Multiply

x = 8 × 0.6 ounces of salt

x = 4.8 ounces of salt

Step 2

The shakers are filled from a container that has 18.6 ounces of salt. If 8 shakers are filled, how much salt will be remaining in the salt container?

This is calculated as:

18.6 ounces of salt - 4.8 ounces of salt

= 13.8 ounces of salt

Answer:

The answer is X = 18

Step-by-step explanation:

2x/3 - 7 = 5

Multiply both sides if the equation by 3 : 2x - 21 = 15

Move the constant to the right hand side and change its sign : 2x = 15 + 21

Calculate 2x = 15 + 21

2x = 36

Divide both sides of the eqaution by 2 : 2x = 36

x = 18

Answer X = 18

Answer:

[tex]Average = 30[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 4^{x - 1} + 2[/tex]

Required

Average [tex]rate\ of\ change[/tex] from 2 to 4

This is calculated using:

[tex]Average = \frac{f(b) - f(a)}{b - a}[/tex]

Where

[tex]a= 2[/tex]  and  [tex]b = 4[/tex]

So:

[tex]Average = \frac{f(4) -f(2)}{4 - 2}[/tex]

[tex]Average = \frac{f(4) -f(2)}{2}[/tex]

Calculate f(2) and f(4)

[tex]f(x) = 4^{x - 1} + 2[/tex]

[tex]f(2) = 4^{2-1} + 2[/tex]

[tex]f(2) = 4 + 2[/tex]

[tex]f(2) = 6[/tex]

[tex]f(4) = 4^{4-1} + 2[/tex]

[tex]f(4) = 4^3 + 2[/tex]

[tex]f(4) = 66[/tex]

So:

[tex]Average = \frac{f(4) -f(2)}{2}[/tex]

[tex]Average = \frac{66 - 6}{2}[/tex]

[tex]Average = \frac{60}{2}[/tex]

[tex]Average = 30[/tex]

Answer: 2

Step-by-step explanation:

Let's substitute the number as x in the equation.

Triple means you multiply it by 3.

Then you add four, and get 10.

We can write that like this:

3x + 4 = 10

Then subtract 4 from both sides:

3x = 6

And then divide both sides by 3:

x = 2

So the number is 2.

Answer:

If you wanted to simplify the equation:

9y - 30 = 6

If you wanted to solve for y:

y = 4

Step-by-step explanation:

3(3y - 10) = 6

9y - 30 = 6

Add 30 to both sides of the equation:

9y - 30 + 30 = 6 + 30

Simplify:

9y = 6 + 30

9y = 36

Divide both sides of the equation by 9:

9y ÷ 9 = 36 ÷ 9

Cancel terms that are in both the numerator and denominator:

y = 36 ÷ 9

y = 4

Answer:

Angle number 5 is adjacent to angle psl

Answer:

No. It's just a 90° angle.

Step-by-step explanation:

Answer:

(here i assume that the daily record is another rectangle)

For a rectangle with width W and length L, the perimeter is:

P = 2*W + 2*L

in this case we know that:

P = 125

W = 15

Replacing these in the perimeter equation we get:

125 = 2*15 + 2*L

125 = 30 + 2*L

125 - 30 = 2*L

95 = 2*L

95/2 = L = 47.5

Now we know that the daily record has a scale factor of 60%.

This means that each measure of this rectangle is (60%/100%) times the equivalent measure of the rectangle garden.

Then if the width of the daily record is W' and the length of the daily record is L'

This means that:

L' = (60%/100%)*L = 0.6*L = 0.6*47.5

W' = (60%/100%)*W = 0.6*W = 0.6*15

Then the perimeter is:

P' = 2*0.6*47.5 + 2*0.6*15 = 75

(notice that is exactly the same than multiplying the original perimeter by (60%/100%) = 0.6)
