Answer:

9√2

Step-by-step explanation:

a^2+b^2=c^2

a^2+b^2=18^2

a^2+b^2=324

324 ÷ 2 = 162

162 + 162 = 324 (on a 45 45 90 right triangle)

81 and 2 are factors of 162

square root of 162

√162 = √81 * 2  = 9√2

a savings account receives 12% simple interest p.a. how long would it take for £30000 to gain £28800 in interest
Elis [28]

Answer:

<h2>8 years</h2>

Step-by-step explanation:

Given,

Principal (P) = £ 30000

Simple Interest ( I ) = £ 28800

Rate (R) = 12%

Time (t) = ?

Now,

t =  \frac{i \times 100}{p \:  \times  \: r}

=  \frac{28800 \times 100}{30000 \times 12}

=  \frac{2880000}{360000}

= 8 \: years

Hence, It would take 8 years.

Hope this helps...

Good luck on your assignment...

Find the least common multiple of 8y^2 and 7m
Flura [38]

Answer:   56y^2m

which is the same as writing 56y^2m

====================================================

Explanation:

Let's focus on the coefficients 8 and 7 for now.

To find the LCM of those values, list out the multiples. Circle the smallest number that can be found in both sets at the same time.

  • multiples of 8 are: 8, 16, 24, 32, 40, 48, 56, 64, ...
  • multiples of 7 are: 7, 14, 21, 28, 35, 42, 49, 56, 63, ....

We see that 56 is the LCM of 7 and 8.

Or you could use this shortcut

LCM = (x*y)/GCF

where x and y are the two numbers. The mention of "GCF" refers to the GCF of x and y. In this case, the GCF is 1 so,

LCM = (x*y)/GCF = (8*7)/1 = 8*7 = 56.

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

Once we determine that, we look at the variable terms now.

The y^2 and m will be tacked onto the 56 to arrive at the final answer 56y^2m

This is because y and m are the unique variables, and we go for the highest exponent of each. It's similar to the LCM formula used earlier.
