Describe a way to make the arithmetic problem 45% x 680 mentally

lord [1]

Answer:

306.

Step-by-step explanation:

Firstly, we are aware 100% of 680 is obviously 680,

Next, we know half of a 100% is 50% therefore half of 680 is 340.

Then, we know 45% is 5% less than 50%

To find 5% of a number mentally, divide it by 10 as 100÷5=20

680÷20=34

Lastly 50% subtracted by 5%: 340-34=306.

Now we know, 45% of 680 is 306.

C) A manufacturer is making 100 times as many bows as Tess to sell in stores nationwide.

Luda [366]

1. Tess is making 12 bows.

2. 100 time as 12 bows = 100 × 12 = 1200 bows

3. In exponent form ; 12 × 10²

Given : Number of bows Tess makes = 100 times as the of x

Let the number of bows Tess makes be x

Thus the number of bows Tess is making is 12.

100 times as many means the number which we have calculated should be multiplied by 100.

thus the number as w2e have found out is 12

so multiplied by 100 will give us 1200

Exponential form means that the given number should be expressed in the form of 10.

As the number which is given to us is 1200n

thus in exponential form we can write it as 12 multiplied by 10 raise to the power as the number of zeros of present.

Here then number of number of zeros is 2

thus 10 raised to the power 2.

Answer:

width of the rectangle=x=4in and length of the rectangle=11in

Step-by-step explanation:

Let the width of the rectangle be x, then according to the question, length is one less than three times its width that is l=3x-1.

Now, width=b=x and length=l=3x-1, thus

Perimeter of the rectangle= 2(l+b)

⇒ $30=2(3x-1+x)$

⇒ $15=(3x-1+x)$

⇒ $15=4x-1$

⇒ $16=4x$

⇒ $x=4in$

Thus, width of the rectangle=x=4in and length of the rectangle=l=3x-1=3(4)-1=12-1=11in.
