**Answer 1**

**Answer:**

1 : 4

**Step-by-step explanation:**

A ratio is simplified by removing the greatest common factor from each of the elements of the ratio.

The ratio 2 : 8 has a factor of 2 in each element, so we can divide by 2 to get the simplest form:

### Answers

**Answer:**

see explanation

**Step-by-step explanation:**

The volume (V) of a cube is calculated as

V = x³ ( x is the side length )

V ≠ 20

Since 20 is not a perfect cube

That is there is no integer when multiplied by itself 3 times gives 20

The crew on a boat catch four fish that weigh a total of 240 pounds. The king mackerel weighs twice as much as the black fin tuna, and the wahoo weighs twice as much as the kind mackerel. The weight of the sailfish is 5 times as much as the black fin tuna. How much does each fish weight?

### Answers

**Answer:**

f + 2f + 4f + 5f = 240lbs

**Step-by-step explanation:**

Black fin tuna (f): let f be the weight of the black fin tuna

King mackerel: 2(f)

Wahoo: 2(2(f))

Sailfish: 5(f)

so f + 2f + 4f + 5f = 240lbs

Solve for w:

### Answers

Isolate the variable by dividing each side by factors that don't contain the variable.

w= 48/lh

The **value of variable w **after solving the **equation** 48 = l × w × h is equal to 48 / (l × h).

**What is algebra ?**

**Algebra** is a branch of mathematics that deals with **various symbols **and the **arithmetic operations **such as division , multiplication , etc.

The given **equation** is :

48 = l × w × h

Let's solve this equation to get the value of w.

We know that to find the **value of variable** , we need to **represent** it into form of other variables or constants.

Here , in the** expression** , 48 = l × w × h , we can write the value of w in form :

48 = l × w × h

or

**dividing both sides by l × h** , we get **value of w **as :

48 / l × h = l × w × h / l × h

or

48 / (l × h) = w

Therefore , the **value of variable w **after solving the equation 48 = l × w × h is equal to 48 / (l × h).

0.09 feet

-0.09 feet

11.1 feet

-68.16 feet

68.16 feet

### Answers

The predicted depth of the dive is **68.16 feet**

Since the equation given is **y=5.1+10.51t,** then, in order to get the predicted depth of the dive, we've to put the value of** t = 6 seconds** into the equation and this will be:

**y = 5.1+10.51t**

y = 5.1 + 10.51(6)

y = 5.1 + 63.06

**y = 68.16 feet**

**Step-by-step explanation:**

**1. **If 27° is the supplement of another angle (or vice versa), that means both angles add up to 180.

**2.** To find the supplement of 27°, we simply subtract that number from 180.

180 - 27153

The **value **of a for the given **square **will be -8.

What is a square?

A square is a **geometrical figure **in which we have four sides each side must be **equal **and the angle between two **adjacent** sides must be 90 degrees.

Area of **square **= Side²

The **perimeter **of the square = 4× side

**Length **of diagonal of square = √(2) × side

Given a **rectangle**, ABCD with a side CD on the x-axis

C(2,0) and D(x,0) because both are on x-axis.

Now,

**coordinate **of B(2,y) and C(x,y)

Now,

By putting B o function,

y = 2²/2 + a

a = y - 2

Now,

y = x²/2 + a

y = x²/2 + y - 2

x²/2 = 2

x = -2 or 2 since 2 is the **coordinate **of C so it will be -2.

Now,

Area of **rectangle**

Length (x - 2) × width(y) = 24

(x - 2)y = 24

By **substitution**,

(-2 - 2)y = 24

y = -6

Now,

y = x²/2 + a

-6 = (-2)²/2 + a

a = -8

Hence "The **value **of a for the given **square **will be -8".
