Round 44,769 to the nearest ten

2 answers:

8 0

When rounding to the nearest ten, always check up on the ones place value. 9 is the ones place value digit: 44769 

As I said before on the other answer: 4 or less, round down, 5 or more, round up.

44769 rounded to the nearest ten is 44770.
Hope this helps!

first we identify wich one is in the tenth position, In this case it is the 6. Now we look at the number next to our number in the ones position. In this case is 9. from 0 to 4 our number would stay the same but from 5-9 it changes so our answer is
44,770

The length of the hypotenuse of a right triangle is 14 inches. If the length of one leg is 6 inches, what is the approximate len

Mice21 [21]

In this question, you need to use Pythagoras' Theorem, c^2 - b^2 = a^2. In this case, C is 14 and B is 6, so you would do 14^2 - 6^2 = 196 - 36 = 160, and the approximate square root of 160 is 12.6 inches, which is your answer.

I hope this helps!

If 24 marks is 60% what is full marks

Luda [366]

If 24 marks is 60 %, then full marks is 40

Solution:

Given that 24 marks is 60 %

We are asked to find the full marks

Let the full marks be "x"

So out of "x" marks, he has got 24 marks

Therefore,

60 % of full marks = 24

60 % of x = 24

$60 \% \times x = 24\\\\\frac{60}{100} \times x = 24\\\\0.6x = 24\\\\x = \frac{24}{0.6}\\\\x = 40$

Therefore, full marks is 40

<h3>Method 2:</h3>

If 60 % is 24, then we have to find what is 100 %

60 % = 24

100 % = x

This forms a proportion, So we can solve the sum by cross multiplying

$60 \% \times x = 24 \times 100 \% \\\\60x = 2400\\\\x=\frac{2400}{60}\\\\x = 40$

Thus full marks is 40

Disks of polycarbonate plastic from a supplier are analyzed for scratch and shock resistance. The results from 100 disks are sum

Naddika [18.5K]

Answer:

P(A) = 86/100

P(B) = 79/100

P(A') = 14/100

P(A U B) = 95/100

P(A' U B) = 84/100

Step-by-step explanation:

i. P(A) = number of disks with high shock resistance/total number of disks

= (70+16)/100

= 86/100

ii. P(B) = number of disks with high scratch resistance/total number of disks

= (70+9)/100

= 79/100

iii. P(A') = number of disks without high shock resistance/total number of disks

= (100-86)/100

= 14/100

iv. P(AUB) = number of disks with high shock resistance or high scratch resistance/total number of disks

= (70+9+16)/100

= 95/100

v. P(A'UB) = number of disks without high shock resistance or with high scratch resistance/total number of disks

= (5+9+70)/100

= 84/100

Combine 2y+1x=40 and y=2x using substitution

fomenos

2(2x) + 1x = 40 or 4x + 1x = 40 is the result of combining by substitution

Solution:

Given that we have to combine 2y + 1x = 40 and y = 2x using substitution method

The substitution method for solving systems of equations involves expressing one variable in terms of another, thus removing one variable from an equation.

Given equations are:

2y + 1x = 40 -------- eqn 1

y = 2x ----------- eqn 2

We can substitute eqn 2 in eqn 1

Which means, substitute y = 2x in place of y in eqn 1

2(2x) + 1x = 40

4x + 1x = 40

5x = 40

x = 8

From eqn 2,

y = 2(8)

y = 16

Thus by combining using substitution method we found the solution
