Answer:

Discount:

20% is .2 as a decimal, so you multiply the value of 12 by .2

12(.2)=2.4

The discount is $2.40

Sale Price:

subtract 2.4 from the price of the original price

12-2.4=9.6

The sale price is $9.60

Answer:

Each can of soda will cost $0.37

Step-by-step explanation:

First you write 24/8.99 = 1/x because you are trying to find the cost for 1 soda

24/8.99 = 1/x

Then you cross multiply.

24*x  8.99*1

24x=8.99

Divide each side by 24

24x/24=8.99/24

x=0.374583

Round it to the nearest hundredths place.

x=0.37

Answer:

the height will be 11 cm

Step-by-step explanation:

As:

given,

base area = 380

volume = 4180

We know,

Base area = l * w

or, 380 = l * w

Then,

volume= l * w * h

or, 4180 = 380 * h

or, 4180/380 = h

or, h = 11

Therefore, the height will be 11 ft.

All the best!!

The height of the rectangular prism is 11 feet

The volume of the prism is given as:

Volume = 4180 cubic feet

The base area of the prism is given as:

Base Area = 380 square feet

The volume of the prism is calculated as:

[tex]Volume = Bh[/tex]

Where, B represents the base area and h represents the height

So, we have:

[tex]4180= 380 \times h[/tex]

Divide both sides by 380

[tex]11 = h[/tex]

Rewrite the equation as:

[tex]h =11[/tex]

Hence, the height of the rectangular prism is 11 feet

The correlation of the values in the tables is the existence of a

relationship between the x and y values.

Correct response:

A table that shows a strong correlation is one in which the y-values can be predicted more or less accurately from the x-values.

The table that shows no correlation is one in which the x and y-values have different patterns;

The level of correlation is given by the correlation coefficient, which is found by the following formula;

[tex]\displaystyle r = \mathbf{ \dfrac{\sum \left(x_i - \overline{x} \right) \cdot \left(y_i - \overline{y} \right)}{\sqrt{\sum \left(x_i - \overline{x} \right)^2 \cdot \sum \left(y_i - \overline{y} \right)^2} }}[/tex]

By plotting the values using MS Excel, we have the values of r², for the tables as follows;

The value of r² for the first table is r² = 0.7307

Therefore;

r ≈ 0.8548 The correlation of the first table is strong.

Second table, r² = 0.8156

r = √(0.8156) ≈ 0.9031 The correlation in the second table is very strong.

Third table, r² = 0.0107

Therefore, r ≈ 0.1034

Fourth table, r² = 0.9342

Therefore, r ≈ 0.9665

The correlation of the x and y-values of the fourth table is very strong indicating the presence of a correlation.

Therefore;

Answer:

5/4kg

Step-by-step explanation:

Given data

Weight of apples bought by Neetu=  3 ¾ kg

Weight of apples bought by  Naren=  2 ½ kg

From the numbers/weights above, Neetu bought more apples

=3 ¾ kg to simple fraction

= 15/4 kg

=2 ½ kg kg to simple fraction

= 5/2 kg

The difference is

=15/4-5/2

=15-10/4

= 5/4kg

Hence  Neetus Apples is 5/4kg morethan Narens Apples

Step-by-step explanation:

Choose any value of x, substitute into the equation for y

Choose x = 1 , then

y = 2(1) + 1 = 2 + 1 = 3

Then (1, 3 ) is an ordered pair on the line

Step-by-step explanation:

the linear inequality is how to measure value of a line through quality and quantity.

Answer:

-4, 6, 16, 26

Step-by-step explanation:

For each y-value, all you need to do is put x into the function or equation wherever there is an x, and the result will be the y-value.

When x = 0; y = 2(0)-4, or y = -4.

When x = 5; y = 2(5)-4 = 10-4 = 6

When x = 10; y = 2(10)-4 = 20-4 = 16

When x = 15; y = 2(15)-4 = 30-4 = 26

Answer:

9.8cm

Step-by-step explanation:

The pythagorean theorem states that, for right triangles, [tex]a^{2}+b^{2} =c^{2}[/tex]. Using this equation, we can solve for the hypotenuse.

a = 9cm

b = 4cm

c = hypotenuse

9^2 + 4^2 =c^2

81 + 16 = c^2

[tex]\sqrt{97} =c[/tex]

9.8 = c

Answer:

Answer: 66

Step-by-step explanation:

From the question, we are informed that a player at a basketball camp set a goal to make 55% if his shots and that he has 120 attempts.

The number of shots that he would he need to make in order to reach his goal will be 55% of 120. This will be:

= 55% × 120

= 55/100 × 120

= 0.55 × 120

= 66

He would need to make 66 shots

Answer:

I'm pretty sure its w=128

"A set of numbers arranged in rows and columns so as to form a rectangular array."

"A matrix formed by combining the columns of two matrices to form a new matrix."

"The mathematical operations that are performed on rows of a matrix."

For given question,

We have been given an augmented matrix.

[tex]\begin{bmatrix}4 & 0 & -4& |& -8 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

We need to perform the row operation 4R3 + R1 → R1

To perform above row operation,

- First multiply the third row by 4. ([tex]4R_3[/tex])

- Add the new third row (4[tex]R_3[/tex]) with the first row.

- Then replace Row 1 with the result.

The resultant augmented matrix would be,

[tex]\begin{bmatrix}\bold{4} & \bold{0} & \bold{0}& |& \bold{4} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

That is,

[tex]\begin{bmatrix}4 & 0 & -4& |& -8 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix} \xrightarrow{\text{4R3+R1}\rightarrow \text{R1}} \begin{bmatrix}\bold{4} & \bold{0} & \bold{0}& |& \bold{4} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

Now, we need to perform the row operation  [tex]\frac{1}{4}[/tex] R1 → R1 on the above resultant augmented matrix.

To perform above row operation,

- Multiply the Row 1 by the reciprocal of 4.

- Then replace Row 1 with the result.

The resultant augmented matrix would be,

[tex]\begin{bmatrix}4 & 0 & -4& |& 4 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix} \xrightarrow{\frac{1}{4} \text{R1}\rightarrow \text{R1}} \begin{bmatrix}\bold{1} & \bold{0} & \bold{0}& |& \bold{1} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

Therefore,

[tex]\begin{bmatrix}4 & 0 & -4& |& -8 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix} \xrightarrow{\text{4R3+R1}\rightarrow \text{R1}} \begin{bmatrix}\bold{4} & \bold{0} & \bold{0}& |& \bold{4} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

and,

[tex]\begin{bmatrix}4 & 0 & -4& |& 4 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix} \xrightarrow{\frac{1}{4} \text{R1}\rightarrow \text{R1}} \begin{bmatrix}\bold{1} & \bold{0} & \bold{0}& |& \bold{1} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]
