The approximate side length of a square game board with an area of 160in² is equal to 12.6 inches.

As given in the question,

Area of the square game board is equal to 160in².

Let 'x' inches be the side length of the square game board.

Area of the square game board = (side length)²

⇒ 160 = ( x )²

Take square root both the sides we get,

    x = √160

⇒ x = 12.649 inches

⇒ x = 12.6 inches( approximately)

Therefore, the approximate side length of a square game board with an area of 160in² is equal to 12.6 inches.

In terms of x and y, Julia's withdrawal from her savings account was equal to y/4 + x/12.

An expression obtained by performing a finite number of algebraic fundamental operations on symbols representing numbers.

Both Ang and Julia have savings balances of x and y dollars, respectively.

Ang = x dollars

Julia = y dollars

Ang offers Julia a third of his savings, which she then transfers to her own savings account.

Amount in Julia's account = (1/3)x + y

Julia then spends a quarter of the total into her savings account.

Amount of money Julia spent = 1/4 × [(1/3)x + y]

                                                 = (1/12)x + (1/4)y

                                                 = y/4 + x/12

Therefore, in terms of x and y, the amount Julia spent from her savings account is y/4 + x/12.

Answer:

I believe it should be 5/6

Step-by-step explanation:

Here's why, the probability of getting a B, or an even number is 3/6 since there are 3 even numbers on a dice. The probability of getting a multiple of 3 is 2/6 since the only multiples of 3 are 1 and 3. Add the 2 together to get 5/6. Hope this helps.

Answer:

[tex]\text{P}(B \text{ or }C)=\dfrac{5}{6}[/tex]

Step-by-step explanation:

Mutually Exclusive Events

For two events, A and B, where A and B are mutually exclusive:

[tex]\boxed{\text{P}(A \text{ or }B)=\text{P}(A)+\text{P}(B)}[/tex]

Probability distribution table:

[tex]\begin{array}{|c|c|c|c|c|c|c|c|}\cline{1-7} x & 1 & 2 & 3 & 4 & 5 & 6 \\\cline{1-7} \text{P}(X=x)\phantom{\dfrac11}&\frac{1}{6}&\frac{1}{6}&\frac{1}{6}&\frac{1}{6}&\frac{1}{6}&\frac{1}{6}\\\cline{1-7}\end{array}[/tex]

where X is the score on a fair, six-sided dice.

P(B or C) means "the probability of rolling an even number or a multiple of 3".

As an even number of a fair, six-sided dice can never be a multiple of 3, the two events B and C are mutually exclusive.

Calculate the probabilities for events B and C.

Event B

Rolling an even number.

[tex]\begin{aligned}\implies \text{P}(X \text{ is even})&=\text{P}(2 \text{ or }4\text{ or }6)\\\\&=\text{P}(X=2)+\text{P}(X=4)+\text{P}(X=6)\\\\& = \dfrac{1}{6}+ \dfrac{1}{6}+ \dfrac{1}{6}\\\\&=\dfrac{3}{6}\end{aligned}[/tex]

Event C

Rolling a multiple of 3.

[tex]\begin{aligned}\implies \text{P}(X \text{ is multiple of 3})&=\text{P}(3 \text{ or }6)\\\\&=\text{P}(X=3)+\text{P}(X=6)\\\\& = \dfrac{1}{6}+ \dfrac{1}{6}\\\\&=\dfrac{2}{6}\end{aligned}[/tex]

Solution

[tex]\begin{aligned}\implies \text{P}(B \text{ or }C)&=\text{P}(B)+\text{P}(C)\\\\& = \dfrac{3}{6}+\dfrac{2}{6}\\\\& = \dfrac{5}{6}\end{aligned}[/tex]

Answer: 100

Step-by-step explanation:

525/84 x 100= 625 total students

625 - 525 = 100

Variable x as the subject of the equation given is expressed as: x = p(m - n).

To make a variable the subject of a formula implies that we express the equation in terms of the variable. Thus, to make a variable the subject of the formula, we have to make the variable stand alone on one side of the equation.

Given the equation, m = n + x/p, make x the subject as explained below:

m = n + x/p [given]

Subtract n from both sides

m - n= n + x/p - n (subtraction property of equality)

m - n = x/p

Multiply both sides by p

p(m - n) = x/p(p) (multiplication property)

p(m - n) = x

x = p(m - n)

the total price paid for a pair of shoes after tax is included is $37.1.

A sales tax is a tax paid to the government for sales of certain types of goods and services.

According to the question,

Cost of the shoes =  $35.             (given)

Total amount/price paid = cost + tax

As the tax percentage is not given in the question, we will assume it to be 6% for example. Then,

Tax amount = 6% of $35

= 6/100*35

= $2.1

Now, total price = cost + tax

= $35+$2.1

= $37.1

Therefore, we conclude that the total price paid for a pair of shoes after tax is included is $37.1.

The output value of f( -4 ) in the function f(x) = -x² - 4x + 42 is 42

A function is simply a relationship that maps one input to one output. Every x-value can only have one y-value to qualify as a function.

Given the data in the question;

To find the output value of f( -4 ), replace all the occurrence of x with -4 in the function and simplify.

f( x ) = -x² - 4x + 42

f( -4 ) = -(-4)² - 4(-4) + 42

f( -4 ) = -( 16 ) + 16 + 42

f( -4 ) = -16 + 16 + 42

f( -4 ) =  42

Therefore, the output value of f( -4 ) is 42, this forms an ordered pair of (-4, 42).

The number of tiles measuring 20cm by 50cm  that are needed to completely cover a wall 4m by 8m is :320.

First step is to convert the Meters to Centimeters

4m = 400cm

8m = 800 cm

Hence,

4m by 8m = 400 cm × 800 cm

4m by 8m = 320,000 cm²

Second step is to determine the how many tiles are needed

Number of needed tiles =  320,000 cm² / ( 20 cm × 50 cm)

Number of needed tiles =  320,000 cm² /1,000 cm²

Number of needed tiles =  320

Therefore 320 tiles are needed.

53 sets

Step-by-step explanation:

730 - 204 = 526

526 / 10 = 52 r 6

therefore he'd have to buy 53 sets to have enough knives.

There are 53 number of sets of knives Jordan could buy for the restaurant to have enough knives.

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The restaurant needs at least 730 knives.

There are currently 204 knives.

And, each set on sale contains 10 knives.

Now,

By the given condition, we formulate;

⇒ 730 ≤ 204 + 10x

Solve for x as;

⇒ 730 ≤ 204 + 10x

⇒ 730 - 204 ≤ 204 + 10x - 204

⇒ 529 ≤  10x

Divide by 10 as;

⇒ 52.9 ≤ x

After rounding, we get;

⇒ 53 ≤ x

Thus, There are 53 number of sets of knives Jordan could buy for the restaurant to have enough knives.
