Answer:

8

Step-by-step explanation:

4.5x+10<=50

4.5x<=50-10

4.5x<=40

x<=8.9

round down because can't go beyond 50

x=8 max

Answer:

8 cups

Step-by-step explanation:

The equation is:

Let \(c\) be amount of cups she can buy.

\(10+4.5c=50\)

Using this equation, we get:

\(10+4.5c=50\)

Subtract 10 from both sides

\(4.5c=40\)

Divide both sides by 4.5

\(c\) ≈ \(8.89\)

Since she can only buy whole cups, the max she can buy is 8 cups.

It is a unique variety of quadrilateral called a parallelogram that has both pairs of opposite sides parallel and equal.

A polygon with has four sides, four angles, and four vertices is called a quadrilateral. The Latin words 'Quadri', which denotes four, and latus, which means side, were combined to form the English word quadrilateral.

Given, Height of the Parallelogram = 2 units

Each segment on the grid is represented as = 1 unit.

So, One side of the Parallelogram = 3 units

Properties of Parallelogram

a. Opposite sides are equal.

b. Opposite sides are parallel.

c. Diagonals Bisect each other.

Step-by-step explanation:

population at 1992 = 3590

Population after Seven years (1999) = 4500

Given two points (t1, P1) and (t2, P2), the slope of the line m can be found.

p1 = (1992, 3590) and p2 = (1999, 4500)

m= ΔP/Δt

m= ((4500-3590))/((1999-1992))

m = 910/7

m=130 is the slope

The linear population function P(t) is

P(t)=130t + P0

Find the Y-Intercept P0

The population function P(t) is measured since the year 1990, year zero. The first moose population was measured in 1992, one year later. This provides an initial condition P (1) = 4500.

P (1) =130 (1) + P0 = 4500

P0 = 4370

P(t)=20t+4630

The moose population P(t) changes linearly year after year. The population function P(t) is measured in terms of t years since 1990.

t= 1990, P (0) =4370

t =1992, P (1) =130 (1) + 4370 = 4500 matches data

t=1999, P (2) = 130(2) + 4370 = 4630

t=2006, P (3) = 130(3) + 4370 = 4760

Answer: The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run).

There are 5 cans left over after painting the walls.

Let x represent the maximum number of trims that can be painted

Since each trim requires 1/2 a can, x trims will take x/2 cans

This cannot exceed 5 cans so we get the inequality:
x/2 ≤  5

Multiplying by 2 both sides of inequality:
x  ≤ 10

In words:
Maximum number of trims that can be painted with 5 cans is 10

Step-by-step explanation:

The total score in the basket game = 139

Falcons score = 9x + 22

Maverick score = 16x - 8

Therefore,

139 = 9x + 22 + 16x - 8

collect like term

139 - 22 + 8 = 9x + 16x

125 = 25x

divide both sides by 25

x = 125/25

x = 5

Falcons score = 9x + 22

Falcons score = 9(5) + 22

Falcons score = 45 + 22

Falcons score = 67

The correct option is (c) \(3x^2 +8x -10=-8\).

Given:

The given equation is,

\(x=\dfrac{-8\pm\sqrt{8^2-4(3)(-1)}} {2(3)}\)---------------------------(1)

Write the general quadratic equation.

\(ax^2 + bx +c=0\)

Write the quadratic formula.

\(x =\dfrac {-b \pm \sqrt{(b^2 - 4ac)} } {2a}\)------------------------------- (2)

Compare equation (1) and (2).

\(a=3\\b=8\\c=-2\)

Answer: 15.8

Step-by-step explanation:

The correct statement is "Stores A and B have an equal spread." (option b).

To determine the spread of the data, we first need to find the range. The range is calculated by subtracting the smallest number from the largest number in a dataset.

For Store A:

The smallest number recorded is 2, and the largest number is 4. Therefore, the range of Store A is 4 - 2 = 2.

For Store B:

The smallest number recorded is 3, and the largest number is 5. Thus, the range of Store B is 5 - 3 = 2.

Comparing the ranges of both stores, we see that both Store A and Store B have the same range, which means the spread of the data is equal for both stores.

Therefore, the correct statement is:

b) Stores A and B have an equal spread.

Answer:

The last option:  \(3 x^{^{\frac{9}{2}}}y^{^{\frac{3}{2}}}\)

Step-by-step explanation:

Main concepts:

Concept 1. Parts of a Radical

Concept 2. Radicals as exponents

Concept 3. Exponent properties

Concept 4. How to simplify a radical

Concept 1. Parts of a Radical

Radicals have a few parts:

If the index isn't shown, it is the default index of "2".  This default index for a radical represents a square root, which is why people sometimes erroneously call the radical symbol a square root even when the index is not 2.

In this situation, the radical's index is 4, and the radicand is 81 x^18 y^6.

Concept 2. Radicals as exponents

For any radical, the entire radical expression can be rewritten equivalently as the radicand raised to the power of the reciprocal of the index of the radical.  In equation form:

\(\sqrt[n]{x} =x^{^{\frac{1}{n}}}\)

So, the original expression can be rewritten as follows:

\(\sqrt[4]{81x^{18}y^{6}}\)

\((81x^{18}y^{6})^{^{\frac{1}{4}}}\)

Concept 3. Exponent properties

There are a number of properties of exponents:

Continuing with our expression, \((81x^{18}y^{6})^{^{\frac{1}{4}}}\), we can apply the "distributive" property since all of the parts are multiplied to each other...

\((81)^{^{\frac{1}{4}}}(x^{18})^{^{\frac{1}{4}}}(y^{6})^{^{\frac{1}{4}}}\)

Applying the "Bases raised to powers, raised again to another power, multiplies powers" rule for the parts with x and y...

\((81)^{^{\frac{1}{4}}}(x^{^{\frac{18}{4}}})(y^{^{\frac{6}{4}}})\)

Reducing those fractions, (both the numerators and denominators have a factor of 2)...

\((81)^{^{\frac{1}{4}}}(x^{^{\frac{9}{2}}})(y^{^{\frac{3}{2}}})\)

Rewriting the exponent of the "81" back as a radical...

\(\sqrt[4]{81} x^{^{\frac{9}{2}}}y^{^{\frac{3}{2}}}\)

Concept 4. How to simplify a radical

For any radical with index "n", the result is the number (or expression) that when multiplied together "n" times gives the radicand.

In our case, the index is 4.  So, we're looking for a number that when multiplied together four times, gives a result of 81.

One method of simplifying radicals is to completely factor the radicand into prime factors, and forms groups (each containing an "n" number of matching items).

Note that 81 factors into 9*9, which further factors into 3*3*3*3

This is a group of 4 matching items, and since the index of the radical is 4, we have found a group that can be factored out of the radical completely:

\(\sqrt[4]{81} =\sqrt[4]{(3*3*3*3)}=3\)

So, our original expression, simplifies finally to \(3 x^{^{\frac{9}{2}}}y^{^{\frac{3}{2}}}\)

This is the last option for the multiple choice.
