Answer: 8.67 x 
Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point. In this problem, we can write 8,670,000,000 as 8.670000000. Notice that there is only one digit to the left of the decimal point. Next, we count the number of places the decimal point would need to move to get back to our starting number which is 8,670,000,000. In this case, the decimal point would need to move 9 places to the right in order to get back to our original number. This would make our exponent positive 9 because we would need to move to the right 9 places. Lastly, we can drop any zeroes that are at the end of the decimal. Therefore, 8,670,000,000can be written in scientific notation as 8.67 x .
Answer:
40 degrees
Step-by-step explanation:
The measurments of corresponding angles in similar shapes are equal.
<C=<Z
<C=180-40-100=40
<Z=40
If you want to know about geometry, the best thing to know would probably what it is. Geometry is a branch of mathematics that deals with the properties and relations of points, lines, surfaces, solids, and higher dimensional analogs.
The surface area of the cube is 384 square mm. Hope it help!
A) The radius of the hemisphere is:
r = d÷2 = 21÷2 = 10.5cm
We can now calculate the volume of a hemisphere:
V = 2/3 π r<span>³
= </span> 2/3 π (10.5)³
= 2423 cm³
As we can consider that 1000cm³ contains 1l, each bowl contains
2423 ÷ 1000 =2.423l.
In total, the milk served will be: 2.423 × 100 = 242l
B) The total cost will be:
242 × 10 = 2420Rs
