Answer:
56.35 ft^2, or 56 7/20 ft^2
Step-by-step explanation:
One way of doing this problem quickly is to convert both measurements into improper fractions before multiplying them:
9 4/5 = 49/5 and 5 3/4 = 23/4.
Then the area of the garden is 49/5 times 23/4, or 1127/20 ft^2, or
56.35 ft^2, or 56 7/20 ft^2.
Answer: 42 students are in the musical
Answer:
1/1560
Step-by-step explanation:
The chance of you winning is 1/40, since there are 40 students and you are one of those students. Since, you cannot win again once you win once, you are eliminated. This leaves us with 39 people left. The chances of your friend being chosen out of the 39 people left is 1/39. Now you must multiply 1/40 and 1/39. After multiplying, you get 1/1560.
The number 1 goes at the end of the number line because it represents 1 whole. Hope this helps c;
The number 12,300 is written 1.23 x 10⁴ as a scientific notation. It's coefficient is 1.23; base is 10⁴ in exponent form.
Scientific notation is a method developed by scientists to shorten the number that expresses a very large number. The scientific notation is based on powers of the base number 10.
Scientific notation has two numbers: coefficient and base. The coefficient must be greater than or equal to 1 and less than 10. The base is always 10 written in exponent form.
12,300 as coefficient in standard form in scientific notation.
1) put decimal after the first digit and drop the zeros. from 12,300 to 1.23 this is the coefficient.
2) to find the exponent, count the number of places from decimal to the end of the number.
1.2300 ; there are 4 places
So the scientific notation is 1.23 x 10⁴
