Mathematics
1 answer:
Makovka662 [10]3 years ago
8 0

Answer:

Step-by-step explanation:

1.

19² = 17² +x²

19² - 17² = x²

√361-289 =x

√72 = 8.5 ≈ x

Area = base*h/2 = 17*8.5/2 ≈ 72.3

Perimeter = 19+17+8.5= 44.5

and so on...

2.

x²= 5² +13²...

A= 5*13/2 =...

P= 5+13+x=...

3.

20² = 10² +x²...

A=10*x/2=...

P=20+10+x=...

4.

x² = 5² +14²...

A=5*14/2 =...

P= 5+14+x = ...

The value of the given expression -1 5/6 x 6 1/2 is equal to  -11 11/12.

As given in the question,

Given expression is equal to :

-1 5/6 x 6 1/2

Simplify the given expression -1 5/6 x 6 1/2 to get the value of the expression:

-1 5/6 x 6 1/2

Convert mixed fraction to proper fraction we have :

-1 5/6 = -11 /6

6 1/2 = 13 /2

-11/6 × 13 /2

= -(11 ×13) / (6×2)

= -143 /12

Convert the proper fraction into mixed fraction we get,

= -11  11/12

Therefore, the value of the given expression -1 5/6 x 6 1/2 is equal to  -11 11/12.

What is 8x-3y=-16,5x+2y=-41
strojnjashka [21]
I'm assuminng you want to find x and y


eliminate

hmm
eliminate y's
3 times 2=6

multiply first equation by 2 and 2nd by 3 and add

16x-6y=-32
<u>15x+6y=-123 +</u>
31x+0y=155

31x=155
divide both sides by 31
x=5
sub back

5x+2y=-41
5(5)+2y=-41
25+2y=-41
minus 25 both sides
2y=-66
divide by 2
y=-33


(x,y)

What is 8.25 as a fraction in simplest form?
vekshin1
8 is a whole number, so this will be the whole number part of our mixed number.

0.25 is a decimal, where 25 is in the HUNDREDths place, so we write 25 as a fraction over 100.

\sf\dfrac{25}{100}

Simplify by dividing 25 to the numerator and denominator.

\sf25\div25=1
\sf100\div25=4

So our fraction is \sf8\dfrac{1}{4}

0.55 is a decimal, where 55 is in the HUNDREDths place, so we write 55 as a fraction over 100.

\sf\dfrac{55}{100}

Simplify by dividing 5 to the numerator and denominator.

\sf55\div5=11
\sf100\div5=20

So our fraction is \sf\dfrac{11}{20}

\sf\dfrac{5}{8}

To convert this to a decimal, just divide 5 / 8

\sf5\div8=0.625

Can some one help me with this question its hard :( down below ill give brainliest

Answer:

The Answer is A. 8

Explanation:

<em>For Answer Choice A: </em>

There's nothing to explain here. It's just the number 8.

<em>For Answer Choice B: </em>

2 · 2 · 2 · 2 is 16. That symbol ( · ) is another way of writing the multiplication symbol. So this problem is essentially 2 x 2 x 2 x 2, which equals 16.

<em>For Answer Choice C: </em>

Well, this one needs no explanation either. It's just the number 16.

<em>For Answer Choice D: </em>

<em />2^{4} is also equal to 16. I'm too lazy to explain how to do this one so yea.  

Hope this helps you. Uh, yea. Have a good day? omg I'm so tired
