Answer:

4/5, 16/20

Step-by-step explanation:

two fractions equivalent to 8/10 are 8/10 (the original fraction itself), 16/20 (obtained by multiplying by 2), and 4/5 (obtained by dividing by 2).

To find two fractions equivalent to 8/10, we can simplify 8/10 to its simplest form and then multiply or divide the numerator and denominator by the same number to find equivalent fractions.

Step 1: Simplify 8/10 to its simplest form:

The greatest common divisor of 8 and 10 is 2. Dividing both the numerator and denominator by 2, we get 4/5.

Step 2: Find equivalent fractions:

We can multiply or divide the numerator and denominator of 8/10 by the same number to find equivalent fractions. Here are two possibilities:

Multiplying both numerator and denominator by 2:

8/10 * 2/2 = 16/20

So, two fractions equivalent to 8/10 are 8/10 (the original fraction itself), 16/20 (obtained by multiplying by 2), and 4/5 (obtained by dividing by 2).

20 heads each head is one rabbit

Answer:

The answer is 20

Step-by-step explanation:

Answer:

(x² - 9)(x² - 1)

Step-by-step explanation:

Using Quadratic trinomials

Factor x⁴ - 10x² + 9

Step 1: Find the two integers whose product of 9 and whose sum of -10

Product

-9 × -1 = 9

Sum

-9 + -1 = -10

Step 2: Use -1 and -9 to complete the factors

x⁴ - 10x² + 9 = (x² - 9)(x² - 1)

Step 3: Use the foil method to check the factors

(x² - 9)(x² - 1) = x⁴ - 1x² - 9x² + 9 = x⁴ - 10x² + 9

Complete question :

A reporter determines a baseball player's batting average, which is a ratio of number of hits to the number of times at bats. The result shown on a calculator as 0.2121....

How many hits would the player be expected to get in 200 at bats? Explain

Answer:

42

Step-by-step explanation:

Given that:

Batting average = number of hits / number of time at bats

Batting average obtained = 0.2121...

If at bats of the player = 200

Hence, number of hits ;

Batting average = number of hits / number of time at bats

0.2121 = number of hits / 200

Number of hits = 0.2121 * 200

Number of hits = 42.42..

= 42 ( approx)

(2x - 6) + 4(x - 3)         use the distributive property a(b + c) = ab + ac

= 2x - 6 + (4)(x) + (4)(-3)

= 2x - 6 + 4x - 12        combine like terms

Answer:

The coordinates of the other endpoint are [tex]B(x,y) = \left(-x-2, -10-\frac{1}{3}\cdot y\right)[/tex].

Step-by-step explanation:

Let [tex]AB[/tex] a line segment in which [tex]M[/tex] is the midpoint. If both [tex]A[/tex] and [tex]M[/tex] are given, then we determine the location of [tex]B[/tex] from definition of midpoint. That is:

[tex]\frac{1}{2}\cdot \vec A + \frac{1}{2}\cdot \vec B = \vec M[/tex] (Eq. 1)

Where:

[tex]\vec A[/tex], [tex]\vec B[/tex] - Endpoints with respect to origin, dimensionless.

[tex]\vec M[/tex] - Midpoint with respect to origin, dimensionless.

[tex]\vec A + \vec B = 2\cdot \vec M[/tex]

[tex]\vec B = 2\cdot \vec M - \vec A[/tex]

If we know that [tex]A(x, y) = \left(x+6,\frac{1}{3}\cdot y \right)[/tex] and [tex]M(x, y) = (2,-5)[/tex], then the coordinates of [tex]\vec B[/tex] are:

[tex]\vec B = 2\cdot (2,-5)-\left(x+6,\frac{1}{3}\cdot y \right)[/tex]

[tex]\vec B = (4,-10)-\left(x+6,\frac{1}{3}\cdot y \right)[/tex]

[tex]\vec B = \left(-x-2, -10-\frac{1}{3}\cdot y\right)[/tex]

The coordinates of the other endpoint are [tex]B(x,y) = \left(-x-2, -10-\frac{1}{3}\cdot y\right)[/tex].

To find:

Solve the equation=?

Solution:

[tex]\to \bold{2(11t+1.5t) = 12- 5t}\\\\\to \bold{22t+3.0t = 12- 5t}\\\\\to \bold{22t+3.0t +5t= 12}\\\\\to \bold{30t= 12}\\\\\to \bold{t= \frac{12}{30}}\\\\\to \bold{t= \frac{4}{10}}\\\\\to \bold{t= 0.4}\\\\[/tex]

Step-by-step explanation:

Answer:

a. (0,-6) and (8,0)

b. [tex]m = 3/4[/tex]

c. [tex]y = 3x/4 - 6[/tex]

Step-by-step explanation:

Given

[tex]3x - 4y = 24[/tex]

Solving (a): Two solutions

To determine the solutions of the equation, we assume values for x and y.

First: Let, x = 0

Substitute 0 for x in the equation

[tex]3x - 4y = 24[/tex]

[tex]3(0) - 4y = 24[/tex]

[tex]- 4y = 24[/tex]

Divide  both sides by -4

[tex]y = 24/-4[/tex]

[tex]y = -6[/tex]

So, one solution is (0,-6)

To determine another solution, we assume that y = 0

Substitute 0 for y in the equation

[tex]3x - 4y = 24[/tex]

[tex]3x -4(0) = 24[/tex]

[tex]3x = 24[/tex]

Divide both sides by 3

[tex]x = 24/3[/tex]

[tex]x = 8[/tex]

So, another solution is (8,0)

Solving (b): The slope of the equation

We have to get the equation in the form: [tex]y = mx + b[/tex]

Where

[tex]m = slope[/tex]

[tex]3x - 4y = 24[/tex]

Subtract 3x from both sides

[tex]3x - 3x - 4y = 24 - 3x[/tex]

[tex]- 4y = 24 - 3x[/tex]

Divide both sides by -4

[tex]y = 24/-4 - 3x/-4[/tex]

[tex]y = -6 + 3x/4[/tex]

[tex]y = 3x/4 - 6[/tex]

By comparison,

[tex]m = 3/4[/tex]

Hence:

[tex]Slope = 3/4[/tex]

Solving (c): Slope intercept form

This has been solved in (b) above

[tex]y = 3x/4 - 6[/tex]
