Form a right-angled triangle where

One leg side of the triangle = opposite side (opp) = perpendicular

= 9 units

Other leg side of the triangle = adjacent side (adj) = base

= $(14 - 10)$ units

= 4 units

Slanted height = Hypotenuse

= $x$ units

Since this is a right-angled, x can be calculated using the Pythagorean Theorem:

$hyp^{2} = opp^{2} + adj^{2}$

$x^{2} = 9^{2} + 4^{2}$

$= 81 + 16$

= $97$

Square root has to be applied to get rid of the square:

∴ x = $\sqrt{97}$ units

= 9.848 units
∴x = 9.85 units (Rounded off to the nearest hundredth)

Ricardo’s goal was to run 40 laps. At the end of the week, he ran 125% of his goal. How many laps is that?

Answers

Answer: He ran 50 laps.

Step-by-step explanation:

40 x 1.25 = 50

Answer:

Step-by-step explanation:

40/1 = 100/1

125% = 100/100 + 25/100

25% of 40 = 10

so you have the 40 laps which equal 100% and you also have 25 percent of the from the 125% and 25 percent of 40 is 10 so the answer is 40 plus 10 wich is 50

How can I find the cube root of 64?

Answers

Answer:

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.
