Six fifths of what number is 60?

Crazy boy [7]

<h3>Hey Buddy,</h3>

<h3>Answer :-</h3>

Answer is 72 .

<h3><u>Explanation :-</u></h3>

$\frac{6}{5} \: of \: what \: number \: is \: 60 \:$

You probably , Know that the number above the fraction line is called the numerator and the number below it is called the denominator. To work out the fraction of any number, we first need to convert that whole number into a fraction as well .

• Any number can be converted to fraction if you use 1 as the denominator:

$\frac{60}{1}$

• So now that we've converted 60 into a fraction, to work out the answer, we put the fraction 6/5 side by side with our new fraction, 60/1 so that we can multiply those two fractions.

• convert the whole number to a fraction and then multiply the numerators and denominators.

$\frac{6 \times 60}{5 \times 1} = \frac{360}{5}$

• Our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.

• You can use our handy GCF calculator to work this out yourself if you want to. We already did that , And the GCF of 360 and 5 is 5.

• We can now divide both the new numerator and the denominator by 5 to simplify this fraction down to its lowest terms.

$\frac{360}{5} = 72$

$\frac{5}{5} = 1$

• When we put that together, we can see that our complete answer is :-

$\frac{72}{1}$

<h3> Hence ,the complete and simplified answer to the question what is 6/5 of 60 is :- 72 .</h3>

Write a single transformation that maps ABC onto A' B' C'

blsea [12.9K]

9514 1404 393

Answer:

Either of ...

(x, y) ⇒ (-x, -y)
Rotation 180° about the origin

Step-by-step explanation:

There are at least two ways to express the transformation that maps each coordinate to its opposite.

1. reflection across the origin: (x, y) ⇒ (-x,-y)

2. rotation 180° (either direction) about the origin.

Take your pick.

Find the value of x if ∡A and ∡B are supplementary angles.

Elanso [62]

Answer:

$x = 30.5$

Step-by-step explanation:

Two angles are supplementary when they add up to 180°.

So we know that:

$C + D = 180$

Supplanting we get:

$(3x-44) + (5x-20) = 180$

We add up the X's.

$8x-44-20 = 180$

$8x-64 = 180$

Then we send 64 to the other side adding:

$8x = 180+64$

$8x = 244$

And then the 8 goes dividing:

$x = 244 : 8$

$x = 30.5$

(-7)(-5) what’s the answer please help

Lina20 [59]

Hello!

Let’s do it step-by-step, shall we? Don’t worry! These problems can be a bit tricky but you’ll get it in no time! It’s really simple.

So, we have (-7)(-5)

This means that the problem will be multiplied because of the parentheses. They substitute the multiplication sign.

So, we have -7 (multiplied by) -5= 35

So your answer would be 35. Hope this helps :) and good luck!

1. Simplify.

<h2>1. The "required option c) 45" is correct.</h2><h2>2. The value of 8 − 2⋅3 + 7 = 9</h2><h2>3. The required "option c) 45" is correct.</h2><h2>4. The required "option a) 40" is correct.</h2><h2>5. The value of $3^2-2.3+5$ = 8</h2>

Step-by-step explanation:

1. We have,

$5^2$ + 20

To find, the value of $5^2$ + 20 = ?

∴ $5^2$ + 20

= 5 × 5 + 20

= 25 + 20

= 45

Thus, the "required option c) 45" is correct.

2. We have,

8 − 2⋅3 + 7

To find, the value of 8 − 2⋅3 + 7 = ?

∴ 8 − 2⋅3 + 7

= 8 - 6 + 7

= 15 - 6

= 9

Thus, the value of 8 − 2⋅3 + 7 = 9

3. We have,

$6^2+3^2$

To find, the value of $6^2+3^2$ = ?

∴ $6^2+3^2$

= 6 × 6 + 3 × 3

= 36 + 9

= 45

Thus, the required "option c) 45" is correct.

4. We have,

$2^{3} +4.8$

To find, the value of $2^{3} +4.8$ = ?

∴ $2^{3} +4.8$

= 2 × 2 × 2 + 4 × 8

= 8 + 32

= 40

Thus, the value of $2^{3} +4.8$ = 40

Thus, the required "option a) 40" is correct.

5 . We have,

$3^2-2.3+5$

To find, the value of $3^2-2.3+5$ = ?

∴ $3^2-2.3+5$

= 3 × 3 - 2 × 3 + 5

= 9 - 6 + 5

= 14 - 6

= 8

Thus, the value of $3^2-2.3+5$ = 8
