1 answer:

4 0

It is a percent increase and it increased by 15%

I got this answer by doing 24.61/21.40 which equals 1.15

You can check this answer by doing 21.40 * .15 on a calculator and when you do this you get 3.21 which you can then add back to 21.40 to get $24.61

Leons older brother is 4 and 3/4 feet tall. Leon is 1/3 foot shorter than his brother .how tall is leon

Mandarinka [93]

Let

x------> height of Leon's older brother

y------> height of Leon

Convert mixed number to an improper fraction

$4\frac{3}{4}\ ft=\frac{4*4+3}{4}= \frac{19}{4}\ ft$

we know that

$x=\frac{19}{4}\ ft$ -----> equation A

$y=x-\frac{1}{3}$ -----> equation B

substitute equation A in equation B

$y=\frac{19}{4}-\frac{1}{3}=\frac{53}{12}\ ft$

Convert to mixed number

$\frac{53}{12}=\frac{48}{12}+\frac{5}{12}=4\frac{5}{12}\ ft$

therefore

<u>the answer is</u>

$4\frac{5}{12}\ ft$

Jeremy is playing a board game and rolls two number cubes. Let A = {the sum of the number cubes is even} and let B = {the sum of

Roman55 [17]

Answer:

A ∩ B = {12}

Step-by-step explanation:

What are the possible even outcomes?

Assuming the number cubes are 1-6,

our possible outcomes run from 2-12, but we are looking for even rolls, so A={2,4,6,8,10,12}.

How many of those are divisible by 3? B={12}.

We are looking for what is in common between these, so

A ∩ B= {12}

Write an equation of the line below.

Veronika [31]

Answer: y=2x+2

Step-by-step explanation:

slope-intercept form: y=ax+b

----------------------------------------

#1 Find the slope

- Use rise/run to find the slope: 8/4=2

- Use slope formula: (2-(-6))/(0-(-4))=8/4=2

#2 Find the y-intercept

- Given the point (2, 0) it is already the y-intercept which is 2

----------------------------------------

a=2

b=2

y=2x+2

Each of three coins has two sides, heads and tails. Represent the heads or tails status of each coin by a logical variable (A fo

jeka94

Answer:

(a) F(A, B, C) = AB'C' + A'BC' + A'B'C

(b) F(A, B, C) = (A' + B' + C')(A' + B + C)(A + B' + C)(A + B + C')(A + B + C)

Step-by-step explanation:

(a) If F(A, B, C) = 1 iff exactly one of the coins is heads, then either

A is heads and the others are tails (AB'C')

B is heads and the others are tails (A'BC')

C is heads and the others are tails (A'B'C)

Hence, as a minterm expansion,

F(A, B, C) = AB'C' + A'BC' + A'B'C

(b) To get the corresponding maxterm expansion, we convert to binary.

$F(A, B, C) = \sum (100, 010, 001) = \sum(4,2,1)$

The maxterm is the product of the complements.

$F(A, B, C) = \prod (0, 3, 5, 6, 7) = \prod(000, 011, 101, 110, 111)$

Expanding,

F(A, B, C) = (A' + B' + C')(A' + B + C)(A + B' + C)(A + B + C')(A + B + C)
