Answer:

1. x = 10

2. x = 4

Step-by-step explanation:

I use the angle ABC method:

AB² + AC² = BC²

6² + 8² = x²

x = 10

AB² + AC² = BC²

3² + x² = 5²

x = 4

HOPE THIS HELPS AND HAVE A NICE DAY <3

Michael has finished 25% of an art project that has taken him a total of 4 hours so far. If he continues to work at the same rat

guapka [62]

It will take him 16 hours because 25 is 1/4 of 100% so 4 times 4 is 16. So 16 is your answer :)

Explain why any of the four operations (+-x / )placed between the two terms 5 and-3/(radical sign) 8 will result in an irrationa

strojnjashka [21]

Answer:

5 + (-3/2√2) = irrational number

5 - (-3/2√2) = irrational number since we have √2

Step by step explanation

Here the given two numbers are 5 and -3/√8.

Here we can rewrite √8 = √2√4

Which is 2√2.

So √8 = 2√2, where √2 is an irrational number.

-3/√8 = -3 / 2√2 = =3/ 2√2 is an irrational number.

When you add, subtract, multiply and divide a whole number (5) with an irrational number (-3/2√2) is always an irrational number.

Therefore, when you do the operations with 5 and -2/2√2 always result in irrational number.

Hope you will understand the concept.

Thank you.

3) Lane and Zack purchased a house for $245,000 in 2016. The house loses 4% of its value each year,

kherson [118]

Answer:

In 2030 Lane & Zack's house be worth $65,739.27.

Step-by-step explanation:

Here, as we know The value of property = $245,000

Rate of depreciation = 4% of its present value

Time = From 2016 to 2030 = 14 years

Now, here: Amount depreciated = -( COMPOUND INTEREST on the value)

Step 1: CALCULATE THE COMPOUND INTEREST on P = $245,000

$A = P(1 + \frac{r}{100} )^t\\\implies A = (245,000)(1 + \frac{4}{100} )^{14} = (245,000)(1 + \frac{4}{100} )^{14}\\=245,000 (\frac{104}{100} )^{14} = 424,260.73$

or, AMOUNT = $424,260.73

Now, AMOUNT = Compound I + Principal

⇒Compound I = A - P = $424,260.73 - $245,000 =$ 179,260

So, the amount of the house by which house depreciates = $ 179,260

⇒The depreciated value = Actual Value - The depreciated amount

= $245,000 - 179,260 = $65,739.27

Hence, in 2030 Lane & Zack's house be worth $65,739.27.
