Answer and Explanation:

To find : Explain why \frac{45}{100} is written as decimal with a 4 in the tenths place and a 5 in the hundredths place ?

Solution :

When we write fraction as decimal we place decimal according to number of zeros in the denominator.

As \frac{45}{100}=0.45

According to place value system,

Ones   |    Tenths        Hundredths

   0               4                    5

As first digit to the right of decimal point is basically tenths place and second digit to the right of decimal point is basically hundredths place.

So, When we write \frac{45}{100} in decimal form i.e. 0.45 then 4 in the tenths place and a 5 in the hundredths place.

A rectangle has an area of 20 cm^2. What will the area be if the rectangle tripled in size?
antoniya [11.8K]

Answer:

  180 cm^2

Step-by-step explanation:

For similar figures the ratio of areas is the square of the ratio of linear dimensions.

We take "tripled in size" to mean that the linear dimensions of the larger rectangle are 3 times those of the smaller rectangle. That means the area of the larger rectangle will be 3² = 9 times the area of the smaller one.

  Area = (3²)(20 cm²) = 180 cm² . . . . area after tripled in size

PLEASE HELP ME I WILL GIVE YOU POINTS
Brilliant_brown [7]

Answer:I got 18.28

Step-by-step explanation:

so for getting the perimeter, you only need the outer line, so you sum the measurements you have for the rectangle: 1+2+2+7= 12. After that you need the circumference of the circle, you can figure it out by using the formula C = 2pi(r) You can find the radius by substracting the known sides of the rectangle attached to the circle from the bottom base and then dividing it in 2, leaving us with a radius of 2. Then we input values; C=2pi(2) which equals 4pi, but we need to divide that in half since it’s only half a circle. That leaves us with 2pi, or 6.28. Then we add the perimeter of the square, which was 12, and 6.28+12= 18.28
