When a number greater than 1 is written in scientific notation, the exponent is positive.
Scientific notation is a way of expressing numbers that are very large or very small using a decimal number between 1 and 10, multiplied by a power of 10. For example, instead of writing the number 100,000,000 as 100,000,000, it can be written in scientific notation as 1 x 10^8.
The exponent of a number in scientific notation is the power of 10 that the decimal number is multiplied by, and it gives the number of places the decimal point is moved to the right or left to obtain the original number. In the example above, the exponent is 8, which indicates that the decimal point has been moved 8 places to the right to get the original number 100,000,000.
When the number is greater than 1, the exponent of scientific notation is positive and indicates that the decimal point is moved to the right.

How far is the portion of her route from A to D? Round to the nearest whole number. Explain. I NEED IT BY TONIGHT SO PLSS SOMEONE HELP ME!
9514 1404 393
Answer:
A to D is about 2087 ft
Step-by-step explanation:
For the portion of the path of interest, the sine and cosine relations apply.
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
__
AB is the adjacent side to the angle marked 33°, with hypotenuse 975 ft.
cos(33°) = AB/(975 ft)
AB = (975 ft)cos(33°) ≈ 817.70 ft
BC is the opposite side in the same triangle.
sin(33°) = BC/(975 ft)
BC = (975 ft)sin(33°) ≈ 531.02 ft
CD is the hypotenuse of the right triangle BCD. The side BC that we know is opposite the given angle, so the sine relation applies.
sin(46°) = BC/CD
CD = BC/sin(46°)
CD = (531.02 ft)/sin(46°) ≈ 738.21 ft
__
Now we know the segments of the path of interest:
A–D = AB +BC +CD
A–D = 817.70 ft + 531.02 ft + 738.21 ft = 2086.93 ft
A–D ≈ 2087 ft
_____
Additional comments
The attachment shows all of the segments computed working counterclockwise from A. The angles in triangle DEF are computed using the Law of Sines from sides DF and DE and angle DEF. Segments EG and GH are computed using the Law of Cosines.
When we get to points F, G, H, we find that there is some inconsistency with the locations that would be computed working clockwise using AB and angle BFA. This inconsistency shows up in an error in the 119° angle in the attached figure.
This means that segments on the back side of the route, along path EFGHA, will vary somewhat depending on how they're computed.
We assume that points B, C, F, G are collinear.

A and B together complete a work in 20days. They worked together for 5days and B leaves. How long will A takes to finish the remaining work if A alone can finish the work 36days.
Answer:
27 days
Step-by-step explanation:
A alone, rate per day = 1/36
A and B together, rate per day = 1 / 20
Total Workdone for 5 days :
1/ 20 * 5 = 5 / 20 = 1/4
Fraction of work left :
1 - 1/4 = 3/4
3 / 4 * 36 /1
= (3 * 36) / 4
= 108 / 4
= 27 days
write the fraction in ascending order.

A scientist mixes x liters of water into a container that had 10 liters of a mixture that is 12% salt and 88% water. The function f(x)=
Answer:
110 liters of water
Step-by-step explanation:
The computation of the number of liters of water added is shown below:
Let us assume the x be the liters of water
f(x) represents the salt percentage in the mixture
Given that
f(x) = 1.2 ÷ x + 10
f(x) = 1% = 1 ÷ 100 = 0.01
Now out the f(x) value in the above equation
0.01 = 1.2 ÷ x + 10
x + 10 = 1.2 ÷ 0.01
x + 10 = 120
x = 110 liters

On a map ,the distance between two towns is 2.6 cm .The scale of the map is 1 cm :50 km. What is the actual distance between the two towns ?
A-100km
B-70km
C-130km
D-150km
And how
Answer:
C-130km
Step-by-step explanation:
50 km = 5 000 000 cm
=> Actual distance between 2 towns = 2.6 x 5 000 000 = 13 000 000 cm = 130 km
=> C-130 km will be the correct ans.
Answer:
C - 130
Step-by-step explanation:
We have two towns that have a distance of 2.6cm, at the same time we know the scale of the map is 1cm : 50km and the question being asked is the actual distance between the two towns.
What we have to do to find the answer is multiply 2.6 by 50, since we know that one centimeter is equal to 50 kilometers on the scale, this is what we must do.
50 * 2.6
Therefore, the distance between the two towns is 130 kilometers.
