What is the inverse of a square root?

Two numbers are in the ratio 3:4 when 4 is added to each term their ratio becomes 10:13. Find the numbers.

Alex17521 [72]

So there’s 2 steps to this. First we subtract what was added on both sides. 10-4 : 13-4 and we get 6:9. This ratio is true, but is not in simplest form, since both numbers are divisible by 3. So after dividing both sides by 3, the answer in simplest form will be 2:3. The correct answer is 2:3

Challenge You have 2 different savings accounts. For Account A, the simple interest earned after 3 months is $1.60. For Account

const2013 [10]

Answer:

$1.28

Note for you:

I hope this helps!

Answer and Step-by-step explanation:

The computation is shown below;

As we know that

The simple interest is

Simple interest = Principal × rate × time

For Account A, the principal would be

2 = Principal × 3.2% × 3

So, the principal is $20.83

For account B, the principal would be

38.50 = Principal × 2.2% × 30

So, the principal is $58.33

Now the interest for both the accounts are as follows

For account 1

= $20.83 × 3.2%

= $0.67

And, for the account 2

= $58.33 × 2.2%

= $1.28

As it can be seen that the account 2 has the highest interest

The same is to be considered

Barbara is building a wooden cabin. The cabin is 424242 meters wide. She obtained a bunch of 272727 meters long wooden beams for

slava [35]

The roof will be in the shape of an isosceles triangle with a base length of 42 m and two sides that are 27 m. The two 27 m beams will have the same angle of elevation since they have to might in the middle.

So to find the angle of elevation, we can split the roof in half vertically to create a right triangle. The base will now be 21 m, and the hypotenuse will be 27 . Now we can use a trigonometry function to solve for the angle. We know the hypotenuse and the side adjacent to the angle, so we can use cosine.

$cos(\theta) = \frac{adjacent}{hypotenuse}$

$cos(\theta)= \frac{21}{27}$

$cos^{-1}( \frac{21}{27})=\theta$

$\theta = 38.9^{\circ}$

The answer is 38.9 degrees
