A wooded piece of land is 68 3/4 acres. If 4/5 of this land is cleared for development, how many acres of wooded land will remain?​

Answers

Answer:

13.75 or 13 3/4 acres

Step-by-step explanation:

68.75*0.2 = 13.75

The number of acres that wooden land remains is 13.75 acres.

Given that,

The wooded piece of land is 68 3 ÷ 4 acres i.e. 68.75 acres.The fourth-fifth of the land is cleared i.e. 0.80.So, the remaining should be 0.20

Therefore the number of acres that wooden land remains is

= 68.75 acres × 0.20

= 13.75 acres.

Therefore we can conclude that The number of acres that wooden land remains is 13.75 acres.

Answers

1/2 step 1 Address formula, input parameters & values.
Input parameters & values:
7
8
& 4
1

7
8
x
4= ?

step 2 Multiply both numerators
= 7 x 4
= 28

step 3 Multiply both denominators
= 8 x 1
= 8

step 4 Use above values of step 2 & 3, and rewrite as below
= 28/8

Thus, 28/8 is equivalent fraction for 7/8 times of 4, and its simplified term is 7/2.

The expression (7/8) x (4/7) simplified to its simplest form is 1/2.

To simplify the expression (7/8) x (4/7), you can multiply the numerators together and the denominators together, and then simplify the resulting fraction if possible.

(7/8) x (4/7)

= (7 x 4) / (8 x 7)

= 28 / 56

To simplify this fraction, we can divide both the numerator and the denominator by their greatest common divisor (GCD), which is 28:

28 / 56

= (28 ÷ 28) / (56 ÷ 28)

= 1 / 2

Therefore, (7/8) x (4/7) simplified to its simplest form is 1/2.

Simplify the expression:
8 ( 5w + 7) + 9 (4w - 7)

Answers

Answer:

40

Step-by-step explanation:

Answer: 1.Remove any grouping symbol such as brackets and parentheses by multiplying factors.

2.Use the exponent rule to remove grouping if the terms are containing exponents.

3.Combine the like terms by addition or subtraction.

4. Combine the constants

Step-by-step explanation:

[tex]8(5w+7) + 9 ( 4w- 7)[/tex]

The first thing we do is distribute

[tex]8(5w+7)& 9(4w-7)[/tex]

We distribute what is outside the parenthesis to everything that is inside the parenthesis

so for 8(5w+7) we do [tex]8x5w = 40w[/tex] and [tex]8x7 = 56[/tex]

so for 9  So  9(4w−7) turns into 36w+63

so now we have 40w+56+36w+−63

now combine like terms

Two students, Alice and Bob, forgot to put their names on their exam papers. The professor knows that Alice does well with probability 0.8, and Bob does well with probability 0.4, independently of each other. What is the probability that exactly one of Alice and Bob does well on the exam

Answers

Answer:

[tex]Probability = 0.56[/tex]

Step-by-step explanation:

Represent the probability that Alice does well with P(A), the probability that Bob does well with P(B).

So, we have:

[tex]P(A) = 0.8[/tex]

[tex]P(B) = 0.4[/tex]

Required

Determine the probability that only one of them do well

This event is represented as: (A and B') or (B and A')

Where B' means Bob does not perform well and A' means Alice does not perform well.

And:

[tex]P(B') = 1 - P(B)[/tex]

[tex]P(A') = 1 - P(A)[/tex]

So, the probability becomes:

[tex]Probability = P(A\ and\ B')\ or\ P(B\ and\ A')[/tex]

[tex]Probability = P(A) * P(B')\ +\ P(B)*P(A')[/tex]

[tex]Probability = P(A) * (1-P(B)) +\ P(B)*(1-P(A))[/tex]

[tex]Probability = 0.8 * (1-0.4) +\ 0.4*(1-0.8)[/tex]

[tex]Probability = 0.8 * 0.6 +\ 0.4*0.2[/tex]

[tex]Probability = 0.48 + 0.08[/tex]

[tex]Probability = 0.56[/tex]

Hence, the required probability is 0.56
