If both containers of orange juice are being sold at the same unit rate, the ratio of ounces to dollars would be the same for the two.

solve the equation by making an inequality:

96 oz. is to $4.80, as 128 oz. is to x

96/ 4.80 = 128/ x

cross multiply 128 and 4.80 to get 614.4

next divide the 614.4 by 96

to get an answer of 6.4

answer: $6.40

Mrs. Start's class paid $5.60 for 4/5 yd of lace for an art project. Later, the class decided to buy another 7 3/4 yd of the sam

MissTica

Answer:

$54.25

Step-by-step explanation:

4/5 yards of lace = $5.60

Price per yard = 5.60 ÷ 4/5

= 5.60 × 5/4

= 28 /4

= $7 per yard

The class decided to buy another 7 3/4 yd

Cost of 7 3/4 yd = cost per yard × number of yards

= $7 × 7 3/4

= $7 × 31/4

= 217 / 4

= $54.26

Cost of 7 3/4 yd = $54.25

3. For the polynomial: ()=−2(+19)3(−14)(+3)2, do the following:A. Create a table of values that have the x-intercepts of p(x) in

Pepsi [2]

Part A. We are given the following polynomial:

$\mleft(\mright)=-2\mleft(+19\mright)^3\mleft(-14\mright)\mleft(+3\mright)^2$

This is a polynomial of the form:

$p=k(x-a)^b(x-c)^d\ldots(x-e)^f$

The x-intercepts are the numbers that make the polynomial zero, that is:

$\begin{gathered} p=0 \\ (x-a)^b(x-c)^d\ldots(x-e)^f=0 \end{gathered}$

The values of x are then found by setting each factor to zero:

$\begin{gathered} (x-a)=0 \\ (x-c)=0 \\ \text{.} \\ \text{.} \\ (x-e)=0 \end{gathered}$

Therefore, this values are:

$\begin{gathered} x=a \\ x=c \\ \text{.} \\ \text{.} \\ x=e \end{gathered}$

In this case, the x-intercepts are:

$\begin{gathered} x=-19 \\ x=14 \\ x=-3 \end{gathered}$

The multiplicity are the exponents of the factor where we got the x-intercept, therefore, the multiplicities are:

Part B. The degree of a polynomial is the sum of its multiplicities, therefore, the degree in this case is:

$\begin{gathered} n=3+1+2 \\ n=6 \end{gathered}$

To determine the end behavior of the polynomial we need to know the sign of the leading coefficient that is, the sign of the coefficient of the term with the highest power. In this case, the leading coefficient is -2, since the degree of the polynomial is an even number this means that both ends are down. If the leading coefficient were a positive number then both ends would go up. In the case that the leading coefficient was positive and the degree and odd number then the left end would be down and the right end would be up, and if the leading coefficient were a negative number and the degree an odd number then the left end would be up and the right end would be down.

Part C. A sketch of the graph is the following:

If the multiplicity is an odd number the graph will cross the x-axis at that x-intercept and if the multiplicity is an even number it will tangent to the x-axis at that x-intercept.

Can someone help me with this please

jenyasd209 [6]

To solve the first question, the angles J and K are perpendicular to each other, that means also that the angles are 90 degrees.

Apart from each other.

This is the total angle measure, that means the sum of the smaller angles must equal 90 degrees.

So the expression would be

2x - 9 + 27 = 90

2x + 18 = 90

2x = 90 - 18

2x = 72

X = 72/2 = 36 degrees.

For the second question since w and v are parallel that means the angles are equal to each other

Thus make the expressions and value equal to each other and solve for x

3x + 60 = 120

3x = 60

X = 20 degrees.

How to get a square root of a given number

bonufazy [111]

Answer:

See below

Step-by-step explanation:

The square root of a number is defined as $\pm y=\sqrt[2]{x}$ where $(\pm y)^{2}$ gives the original number. For example, $\sqrt{4}=\pm2$ because $2^{2}=2*2=4$ and $(-2)^{2}=-2*-2=4$ .
