Answer:
6:9 ÷3
2:3
Step-by-step explanation:
1st write the ratio then simplify it with dividing with the Highest common factor on both sides
Let the two numbers be x and x + 40, then
x + x + 40 = 180
2x = 180 - 40 = 140
x = 140/2 = 70
Therefore, the measures of the two angles are 70° and 70 + 40 = 110°
6.9 x 10⁷ is a scientific notation.
6.9 x 10⁷ in standard form is 69,000,000
Scientific notation is used to represent very large numbers or very small numbers.
Scientific notation has three parts. Its parts are the coefficient, base of ten, and the exponents.
6.9 is the coefficient
10 is the base of 10
7 is the exponent
The must always be 1 digit before the decimal point in the scientific notation.
The exponent tells us the number of places the decimal point has moved. Its sign tells us the direction of the decimal point's movement.
Since the exponent is positive, it tells us that the decimal point moved from right to left.
69000000. to 6.9000000
If the exponent had a negative sign, it means that the decimal point moved from left to right.
example: 6.9 x 10⁻⁷
its standard form would have been .00000069
We will say that the eastbound cyclist is going x mph. This means that the westbound cyclist is going x+3 mph.
They are both cycling for 6 hours and end up 162 miles apart.
Distance=rate*time
6x+6(x+3)=162
6x+6x+18+162
12x=144
x=12
So, the eastbound cyclist is going 12 mph.
Remember the westbound cyclist is going 3 mph faster, so s/he is going 15 mph.
Hope this helps!!
