Step-by-step explanation:

Answer:

-15 meters

Step-by-step explanation:

Elevation means the height to which something is elevated. If the object is above sea level then it is positive. If the object is below sea level it is negative.

The elevation of the surface of the ocean is, - 15 meters.

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

A fish is 15 meters below the surface of the ocean.

Here, The fish is 15 meters below the surface of the ocean.

Hence, Its elevation shows in negative sign.

Thus, We get;

The elevation of the surface of the ocean = - 15 meters.

Answer:

I think 4/10 pizza he had ate .

The amount of the pizza he ate will be 9 / 40.

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.

There are ten pieces of pizza.

Anthony ate 1/8 of the pizza for dinner.

Then the amount of pizza left will be

⇒ 1 – 1/8

⇒ (8 – 1) / 8

⇒ 7/8

He ate 3/10 for a bedtime snack.

Then the amount of the pizza will be

⇒ 7/8 – 1/10

⇒ 31/40

The pizza has he eaten in all.

Then the amount of the pizza he ate will be

⇒ 1 – 31/40

⇒ 9 / 40

Then the amount of the pizza he ate will be 9 / 40.

Answer:

The length of DE is 5 because they are similar triangle .

Explanation:

The triangles are similar. We can use the SAS similarity theorem to prove that claim.

Because the triangles are similar, the corresponding sides form a proportion like shown below

12/8 = 9/x

12x = 8*9 ... cross multiply

12x = 72

x = 72/12

x = 6 which is why the answer is choice B

The speed of the boat will be 12.18 mph, and the angle of its direction measured from the positive x-axis will be 224.3°

First, let's define North as the positive y-axis and east as the positive x-axis.

In this coordinate axis, the angle S 60° W is equal to 210°.

Then the velocity of the boat will be:

v = (17mph*cos(210°), 17mph*sin(210°))

Now we also need to add the speed of the river, which is 6mph to the east, then the final velocity of the boat will be:

v = (17mph*cos(210°) + 6mph, 17mph*sin(210°))

v = (-8.72mph, -8.5 mph)

Then the speed of the boat will be:

|v| = √( (-8.72mph)^2 + (-8.5 mph)^2)  =12.18 mph

And the angle, measured from the positive x-axis, will be given by the arctangent of the quotient between the y-component and the x-component:

Atan(-8.5 mph/-8.72mph) = 224.3°
