Ancient Egyptians did not write the fraction 4/5 as 4/5. Instead they used unit fractions. The numerator of a unit fraction is a

lways 1.No denominator used to represent a given fraction can be repeated. For this reason, Egyptians would have written 4/5 as 1/2 + 1/5 + 1/10 and not as 1/2 + 1/10 + 1/10 + 1/10. Write each of the following as a sum of unit fractions.

<u>3/4</u> = 1/2 + 1/4

<u>5/8</u> = 1/2 + 1/8

<u>7/12</u> = 1/2 + 1/12

Principal = $2,400<br> Rate = 4%<br> Time = 30 months

grandymaker [24]

Answer:

$240

Step-by-step explanation:

I = prt

I = (2,400) (0.04) (2.5)

note: I changed 4% to a decimal and 30 months to 2.5 years

I = 96 (2.5)

I = 240 <-- The interest

------------------------------------------------------------------------------------------------------------

The simple interest accumulated on a principal of $ 2,400.00 at a rate of 4% per year for 2.5 years (30 months) is $240.00.

---------------------------------------------------------------------------------------------------------

The diagram shows a right triangle and three squares. The area of the largest square is 55 units.

Keith_Richards [23]

Answer:

A

B

C

Step-by-step explanation:

Well the sides of the smaller squares have to be greater than the biggest when put together.

a + b > c

So we need to find the square root of 55.

$\sqrt{55}$

≅ <u>7.4</u>

<u />

Now for option A)

srt ⇒ 12 ≅3.5

srt ⇒ 43 ≅ 6.6

3.5 + 6.6 = <u>10.1</u>

So option A is correct.

Option B)

srt ⇒ 14 ≅ 3.7

srt ⇒ 40 ≅ 6.3

3.7 + 6.3 = <u>10</u>

So option B is also correct.

Option C)

srt ⇒ 16 = 4

srt ⇒ 37 ≅ 6.1

4 + 6.1 = <u>10.1</u>

So option C is also correct.

<em>Therefore,</em>

<em>all options are correct.</em>

<em>Hope this helps :)</em>

Length of DA: 90°
They are placed on a obtuse angle, which is 180° and DA are also placed on a right angle, so that means 180°-90°=90°

Length of AB: 180°
Their placed on a obtuse angle, therefore it will just be 180°

ADF=BDE because, both of them are right angles. This means their degrees will equal (90°=90°).

Hopefully this helps, sorry if I turn out to be wrong!

If f(x) = x^2-1 which of the following ordered pairs would be on the graph of f(x)

Alex Ar [27]

These following ordered pairs are on the graph:

(0,1)
(5, 24)
(-2,3)

-------------------------------

An ordered pair (x, f(x)) will be on the graph if replacing them into the equation, we get an equivalence.

-------------------------------

The equation is:

$f(x) = x^2 - 1$

-------------------------------

(0,1)

Here, we test $x = 0, f(x) = 1$

Replacing into the equation:

$1 = 0^2 - 1$

$1 = -1$

False, so not on the graph.

-------------------------------

(0,1)

Here, we test $x = 1, f(x) = 0$

Replacing into the equation:

$0 = 1^2 - 1$

$0 = 0$

True, so on the graph.

-------------------------------

(3,5)

Here, we test $x = 3, f(x) = 5$

Replacing into the equation:

$5 = 3^2 - 1$

$5 = 8$

False, so not on the graph.

-------------------------------

(5,24)

Here, we test $x = 5, f(x) = 24$

Replacing into the equation:

$24 = 5^2 - 1$

$24 = 24$

True, so on the graph.

-------------------------------

(-2,3)

Here, we test $x = -2, f(x) = 3$

Replacing into the equation:

$3 = (-2)^2 - 1$

$3 = 3$

True, so on the graph.

-------------------------------

(-4,-17)

Here, we test $x = -4, f(x) = -17$

Replacing into the equation:

$-17 = (-4)^2 - 1$

$-17 = 15$

False, so not on the graph.
