$2,500 {(1/.005) - [1/.005(1.005)12 ×25]}

Afina-wow [57]

Answer:

-12771250

Step-by-step explanation:

We want to evaluate;

$2500( \frac{1}{0.005} - ( \frac{1}{0.005} \times 1.005 ^{12} \times 25)$

We expand to get;

$2500 \times \frac{1}{0.005} - 2500( \frac{1}{0.005} \times 1.005 ^{12} \times 25)$

$500000 - 500000 \times 1.0617 \times 25$

We multiply to get;

$500000 - 13271250$

We now subtract to get :

$= - 12771250$

A bluebird is sitting in her nest 10 feet up in a tree when she looks down and sees a cat and a worm. she decides to use math to

GarryVolchara [31]

Answer:

12.2 feet

Step-by-step explanation:

The key to this problem is trigonometry.

Imagine a right triangle. With a height, 10 ft (representing the tree's height), and a base of 7 ft (representing the horizontal distance to the worm).

Now the hypoteneuse length, or otherwise the distance from the worm is unknown.

So this is where we can use the pythagorean theorem.

$a^2 + b^2 = c^2$

$c$ here is the hypoteneuse length, and $a$ and $b$ are the other lengths of the triangle.

Since we know a and b we can solve for c.

But first we will square root both sides of the equation to get $c$ and not $c^2$ .

$\sqrt{a^2 + b^2} = c$

Now just plug in our values for a and b respectively. (It doesn't matter what number replaces a or b, just make sure you are replacing a and b with the 2 known values) Calculate.

$\sqrt{10^2 + 7^2} = \sqrt{100 + 49} = \sqrt{149} = 12.206....$

Round to the nearest tenth.

$12.2$ feet

You save $35 each week. You now have $140. You plan to save enough money for a cruise that costs $1,050. Write and solve an equa

Cloud [144]

Answer:

It will 26 weeks to save for the cruise starting from a balance of $140

(It will take 30 weeks in total, if you start saving from $0)

Step-by-step explanation:

let x = number of weeks

Given starting balance = $140

⇒ 140 + 35x = 1050

⇒ 35x = 1050 - 140

⇒ 35x = 910

⇒ x = 910 ÷ 35

⇒ x = 26

If a spinner is spun 5 times then each event is independent <br><br> True or false?

steposvetlana [31]

Answer:

True

Step-by-step explanation:

Each time a spinner is spun, there is an equal chance that each result will occur, thus each of these spins are independent.

Zepler [3.9K]

Are there any dimensions on the triangle? or is it in terms of s? if so the answer would be 2s/sqrt(3) or you can rationalize the bottom and youd get 2sqrt(3)s/3
