if y varies inversely as the square of x and y= 7/48 when x=4 find y when x=3

If we have to find the total number of coins then we can use the following rule:

Thus,

︎⠀⠀ ⠀⠀ ⠀⠀ ⠀︎⠀⠀ ⠀⠀ ⠀8×Total Number of Purse.

Answer:

C

because:

[tex]y = 0.074x + 50.48 \: \: \\ \: when \: x = 2158 \\ y = 0.074(2158) + 50.48 \\ y = 210 \\ when \: x = 2040 \\ y = 0.074(2040) + 50.48 \\ y = 200 \\ [/tex]

So the equation can be used to calculate fair housing prices is:

[tex]y = 0.074x + 50.48[/tex]

Answer:

8 (hopefully)

Step-by-step explanation:

Exponents and Fractions always get dealt with before Math Symbols and Parentheses.

But other than that, you ALWAYS do times or divide from left to right, than plus or minus left to right (unless there's a parentheses, go for the number in the parentheses).

2 by the power of 3 (or 2^3) splits into three twos.

2 * 2 = 4 * 2 = 8 (2^3 = 8)

7 * 8 = 56

56 divided by 4 = 14

8 + 14 = 22

Long story sort

2^3 + 7 * 8 */. 4

8 + 7 * 8 */. 4

8 + 56 */. 4

8 + 14

22

Now than I do not remember what you're supposed to with the "= [Number]" but I do believe you're supposed to sum the left and the right. So I do believe it's 8, now than remember this is not an exact answer, due to not knowing what it's properly to be.

Answer:

  (2³ +7)·8÷4 = 30

Step-by-step explanation:

You want to add parentheses to make a true statement from ...

  2³ +7·8÷4 = 30

We recognize that 2³ +7 = 15 and 8÷4 = 2, and the product of these is 30. So, we need to insert parentheses to make (2³ +7) be evaluated before multiplying by 8 and dividing by 4:

  (2³ +7) · 8 ÷ 4 = 30

Area

Answer:

Length = 5

Width = 4

Area = 20

Triangle area = 10

Step-by-step explanation:

The length of the rectangle = the longest leg = 5 units

The width of the rectangle = the shortest leg = 4 units

The area of the rectangle = width x length = 4 x 5 = 20 units²

The area of the triangle = 1/2 the area of the rectangle = 20 ÷ 2 = 10 units²

Answer:

-12x+3 greater than or equal to 5

-12x greater than or equal to to 2

To turn the negative sign of -12x into positive, we multiply both sides by minus, which shifts the inequality sign.

So, 12x less than or equal to 2

x is less than or equal to 1/6

Therefore, 0, -1, -3, -4 and -6 satisfy this inequality

Answer:

The answer is 45

Step-by-step explanation:

135 and 225

Here, 225 > 135

225 = 135 × 1 + 90

Since remainder ≠ 0, we apply division Lemma to 135 and 90

135 = 90 × 1 + 45

Since remainder ≠ 0, we apply division Lemma to 90 and 45

90 = 45 × 2 + 0

Since remainder = 0, divisor 45 is the HCF

Thus, HCF (135, 225) = 45

-TheUnknownScientist 72

Answer:

HCF = 45

Step-by-step explanation:

225 = (135 × p) + q

⇒ 225 = (135×1) + 90

⇒ 135 = (90 × 1) + 45

⇒ 90 = (45 × 2) + 0

HCF (135, 225) = 45

Using a system of equations, it is found that the trains will be side by side in 15 seconds.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the equations are:

[tex]y_1 = 229t[/tex]

[tex]y_2 = 149t + 1200[/tex]

They will be side-by-side when:

[tex]y_1 = y_2[/tex]

Hence:

[tex]229t = 149t + 1200[/tex]

[tex]80t = 1200[/tex]

[tex]t = \frac{1200}{80}[/tex]

[tex]t = 15[/tex]

The trains will be side by side in 15 seconds.

A ratio can be expressed three (3) ways. The ratio of A to B can be expressed as any of ...

  A to B

  A : B

  A/B

It will be in reduced form when the numbers are mutually prime (have no common factors).

__

The ratio of burgers without onions to burgers with onions is ...

  without : with = 8 : 2 = 4 : 1

__

The ratio of history visitors (5) to science visitors (44) is ...

  history : science = 5 : 44

_____

Additional comment

Some problems can be fairly easily worked by considering the difference between A and B in the ratio A/B. However, those differences are irrelevant to this problem. Here, you're simply asked to write the ratios.

We note that the ratios asked for reverse the appearance of the numbers given in the problem. That is, the second number in the ratio requested is the number described first. This requires you pay attention to what you are given and what is requested. (That's always a good idea.)

y = 2(2) + 7 =11

There are several ways to prove a mathematical statement. These ways include: by contradiction, by induction, contraposition, etc

To prove the statement, we make use of proof by contradiction

From the question:

x is a composite number such that: x > 1

This means that 1 < a < x is a factor of x

This can be represented as:

[tex]x = a * b[/tex]

Where:

Assume that b is less than or equal to a.

Also, let

[tex]b > \sqrt x[/tex]​

This means that:

[tex]\sqrt x < b \ge a[/tex]

The above becomes

[tex]\sqrt x < a[/tex]

Rewrite as:

[tex]a > \sqrt x[/tex]

So, we have:

[tex]x = a * b > \sqrt x * \sqrt x = x[/tex]

The above means that:

[tex]x > x[/tex]

The above inequality is a contradiction because, a number x cannot be greater than itself

This means that, the supposition is wrong.

Hence, the given statement has been proved by contradiction

The amount of interest will be $50 for the investment.

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific amount of time.

Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to calculate interest, the principal amount in simple interest remains constant.

Given that Krisi took out a $500 discounted loan calculated using a simple interest rate of 5% for a period of 2 years.

Answer:

80

Step-by-step explanation:

When we first look at this, it generally says "90% of what number is 72?" so that's what we can do.

We can change 90% into a decimal, and put in x, which is what our answer will be!

[tex]0.9*x=72[/tex]

We can multiply both sides of this equation by 100, and then divide by 90. After all of this, we have

the volume of a box is the length width and height all multiplied together

so this is what the equation would look like

5(6)(13)

you can split this up into

5(6) * 13

so 5(6) is 30

30(13)

this is 390

so the box is 390 cubic centimeters
