This is equivalent to:

(2.2533/2.59)(10^8/10^4)

(0.87)(10^4) which is:

0.87X10^4 which is equal to:

0.87X10000 which is equal to:

8.7X1000 and since 1000=10^3 we can say:

8.7X10^3

A kitchen measures 3.75 meters by 4.2 meters.

dalvyx [7]

Answer:

a. $A_{(kitchen)}=15.75\ m^2$

b. $A_{(total)}=39.375\ m^2$

Step-by-step explanation:

The formula for calculate the area of a rectangle is:

$A=lw$

Where "l" is the lenght and "w" is the width

a. We know that the kitchen measures 3.75 meters by 4.2 meters; then we can say that:

$l=3.75\ m\\\\w=4.2\ m$

Therefore, substituting these values into the formula, we get that the area of the kitchen is:

$A_{(kitchen)}=(3.75\ m)(4.2\ m)=15.75\ m^2$

b. The area of the living room is one and a half times (1.5 times) that of the kitchen, this is:

$A_{(living)}=(1.5)(15.75\ m)=23.625\ m^2$

Therefore, the total of the living room and the kitchen is:

$A_{(total)}=15.75\ m^2+23.625\ m^2=39.375\ m^2$

During a school race, Sonic ran around the entire track 5 times in 10 seconds. Everyone was shocked by his speed, which was equa

Aleonysh [2.5K]

Step-by-step explanation:

there is no diagram here.

I assume that the race track is a rectangle in the middle and two half-circles at the left and right ends, and that the length of the rectangle is D = 2R. which makes the rectangle actually a square, as the width is the diameter of the (half-)circles, which is also 2R.

Sonic ran the track 5 times in 10 seconds with a speed of 321 m/s.

that means he ran 10×321 m in 10 seconds = 3210 m.

so, 5 times the track is 3210 m, which means that the track itself is 3210/5 = 642 m long.

and based on the assumptions above the track consists of 2 times the length of the rectangle (or square), and the full circumference of a circle with radius R (2 half-circles make one full circle).

we know the formula for the circumference of a circle :

2×pi×radius

so, we have then

642 = 2×2R + 2×pi×R = R×(4 + 2×pi)

R = 642 / (4 + 2×pi) = 62.43201701...

and when using the requested "cut-off" pi = 3.14, we get

R = 642 / (4 + 2×3.14) = 62.45136187...

and that is rounded 62.5

so, the second answer option is correct.
