PLEASE HELP ! 12 POINTs!

Mathematics
1 answer:
lisov135 [29]3 years ago
3 0

Answer:

Perimeter = 101.496 cm

Step-by-step explanation:

draw line from point C that is perpendicular to line AD. Call that point E.

tan 43° = 16.7/ED

0.9325 = 16.7/ED

ED = 17.909 cm

sin 43° = 16.7/CD

0.6820 = 16.7/CD

CD = 24.487 cm

Perimeter = AB + BC + CD + ED + AE

Perimeter = 16.7 + 21.2 + 24.487 + 17.909 + 21.2 = 101.496 cm

Grace is practicing free throws. The probability that she will shoot the ball into the basket is 5/9 . What is the probability t
Naddika [18.5K]

Answer:

There is a 25/81 probability that Grace will make both of her next two shots.

Step-by-step explanation:

The probability of her making the first shot is 5/9.

The probability of her also making the shot after that is still 5/9, that does not change.

To find the probability of both of those events, multiply the fractions.

5/9 * 5/9

25/81.

explain your process of converting a mixed number to an improper fraction.explain your process of converting a improper fraction
Sophie [7]
So I'll start with the mixed number to improper fraction.
Step one - multiply the denominator and the whole number.
Step two- take your product and add it to the numerator
Step three- the sum is the numerator of the mixed number and the original denominator is the denominator
___________________________
Now for improper fraction to mixed number
Step one- see how many times the denominator goes into the numerator (ex. 2 goes into 9, 4 times With one left over)
Step two -the 4 becomes the whole number and the 1 the numerator
Step three- use the same denominator

Let f(x) = 3x + 2 and g(x) =x - 3. Find f(x) - g(x). Question 3 options: 2x - 5 4x - 1 2x - 1 2x + 5
Alexxx [7]

Answer: f(x)-g(x)=2x+5

Step by step:

f(x) = 3x+2

g(x) = x-3

f(x)-g(x) = 3x +2 - (x-3) = 3x + 2-x+3=2x+5
