Diagonal formula: a^2 + b^2 = c^2

Now, solve for the length of the diagonal.

8^2 + 3^2 = c^2

64 + 9 = c^2

73 = c^2

√73 = √c^2

8.5 ≈ c (This is the diagonal and its rounded).

Best of Luck!

Using pythagoras a^2 + b^2 = c^2
8^2 + 3^2 = c^2
64 + 9 = 73
The square root of 73 is 8.54
So the length of the diagonals are 8.54cm

A sum of money was divided between Riaz ad Ali in the ratio of 3:2. Riaz received the larger share. Write the amount each receiv

sasho [114]

Riaz : Ali
3 : 2

Add the two values; so 3 + 2 is 5

Then 100/5 = 20

So: 20 x 3 = 60
and 20 x 2 = 40

Riaz = 60%
Ali = 40%

Then write 60% and 40% as a fraction:
60% = 3/5 (3 over 5)
40% = 2/5 (2 over 5)

The answers are in bold :)

The standard diameter of a golf ball is 42. 67 mm. A golf ball factory does quality control on the balls it manufactures. Golf b

levacccp [35]

Using function theory, the function that could represent this situation is

f(x) = |42. 67 – x| .

It is given that

The standard diameter of the golf ball = is 42.67

Allowable discrepancy = ±0.002

So upper limit of diameter = 42.672

The lower limit of diameter = 42.668

We need a function that can help in finding a discrepancy.

<h3>What is a function?</h3>

A function is a rule which determines the relation between two variables.

The correct function that could represent this situation will be

f(x ) = |42. 67 – x|

Where x is the diameter of the ball produced.

For example, if a ball of diameter 42.665 is produced

f(x) = |42. 67 – x|

f(42.665) = |42. 67 – 42.670| = 0.005 which is more than the permitted tolerance i.e 0.002.

So, one can easily decide whether to stop production or not.

Therefore, the function that could represent this situation is

f(x) = |42. 67 – x| .

Answer:

A) 6

Step-by-step explanation:

The ratio is found by dividing a sequence value by the one before. It is "common" if it is the same for any pair of sequence values.

r = y2/y1 = 36/6 = 6

The common ratio is 6.

jessica gave the cashier $20 to pay for four pair of socks the cashier gave her $4.12 in change each pair of socks cost the same

Deffense [45]

The cost price of each pair of socks is 3 dollars and 97 cents

The total money paid by Jessica for 4 pair of socks = $20

The money that the cashier returned = $4.12

It is also given that, each pair of sock would cost same price

We need to find, The cost price of each pair of socks

To do that, first let's find

The amount that was paid for 4 pair of socks = 20 - 4.12 = $15.88

Now,

The cost price of one pair of sock = $\frac{15.88}{4}$

= $3.97

= 3 dollars and 97 cents
