x + 2y = 65

Answer:

4.4 inches

Step-by-step explanation:

To work out the length of each side of the cube you would need to cube root of the volume as seen below:

[tex] \sqrt[3]{85.184} [/tex]

And this gives the answer 4.4 inches.

Answer:

Volume = Length * Width * Height

A cube has equal length, width, and height values.

[tex]\sqrt[3]{85.184}[/tex] is 4.4

So the length of each side is 4.4 units

Answer:

$28.20

Step-by-step explanation:

Let's set up an equation.

Let b be the cost of a bumper sticker.

Since the sum of the prices of 11 bumper stickers total up to $10.34, we can set up an equation!

11b = 10.34

Dividing by 11 on both sides,

b  = 0.94

Plugging in b into 30b,

30(0.94)

We get

$28.20

Answer:

$28.20

Step-by-step explanation:

First, find out how much each bumper sticker costs.

Assuming that the cost of each bumper sticker is the same, the following equation represents how much one bumper sticker costs

11x =  10.34

Solve for x [divide both sides by 11]

x = 0.94

So, one bumper sticker costs $0.94

Now, find out how many 30 bumper sticker costs.

The following equation represents how much 30 stickers cost.

30x = y

X represents the cost of one sticker and y represents the cost of 30 stickers.

We already know the value of x [one bumper sticker's cost] which is $0.94, so subsitute that in for x.

30[0.94] = y

28.2 = y

So, 30 bumper stickers cost $28.20.

I hope this helps!

Answer:

Absolute error = 39

Percent Error = 6.10%

Step-by-step explanation:

Actual value = 639 pounds

Observed Value = 600 pounds

The formula to find absolute error is:

Absolute Error = Actual value - Observed Value

                        = 639 - 600

                        = 39

The formula to find Percent error is:

Percent Error = (Actual value - Observed Value / Actual value)*100

                       = (639 - 600/639)*100

                       = 6.10%

Answer:

Absolute error = 39 pounds

Percent error = 6.10%

Step-by-step explanation:

We know that the estimated weight was 600 pounds while the actual weight of the beam was 639 pounds.

So we will find their difference to get the absolute error.

Absolute error = 639 - 600 = 39 pounds

We will use the following formula to find the percent error.

Percent error = (Estimated value - actual value / actual value) * 100

Percent error = 639 - 600 / 600 * 100 = 6.10%

The formula of a surface area of a cone:

[tex]S.A.=\pi r^2+\pi rl[/tex]

We have r= 8in and l = 21in. Substitute:

[tex]L.A.=\pi(8)(21)=168\pi\ in^2[/tex]

[tex]S.A.=\pi(8^2)+168\pi=232\pi\ in^2[/tex]

Answer:

D- (3, 1).

Step-by-step explanation: Add the first equation so you can figure out what x equals. Then, plug the value into your next equation in order to find y. Hope this helps. :)

For this case we have the following system of equations:

[tex]2x + 4y = 10\\3x-4y = 5[/tex]

We solve by the method of elimination, then:

We add both equations:

[tex]2x + 3x = 10 + 5\\5x = 15\\x = \frac {15} {5}\\x = 3[/tex]

We find the value of y:

[tex]3 (3) -4y = 5\\9-4y = 5\\9-5 = 4y\\4 = 4y\\y = \frac {4} {4}\\y = 1[/tex]

Option D

the answer for this question is the dilation is reduction

The statement which is true about these rectangles is:

          The dilation is an enlargement.

Dilation Transformation--

Here we see that each of the sides of the original figure is multiplied by "1.5" to obtain a larger rectangle.

This means that the dilation is a enlargement.

( since the scalar is strictly greater than one )

OK..

So first you need to divide it into two shapes, rectangle and square

Then u find the area for rectangle and add it with the area of square..

Answer:

It will shift down 6 units.

ANSWER

B) It will shift down 6 units.

EXPLANATION

The given function is

y=15x+2

We want to find how the graph of this function will change if the function is transformed to

y=15x-4

We rewrite this function in terms of the first one to get:

y=15x+2+-6

Hence the function with shift down 6 units.

Answer:

No,yes,yes,no,yes

Step-by-step explanation:

A^2 + b^2 = c^2

C is your hypotenuse or the longest side of the triangle; you plug in your values and solve for the missing side:

15^2 + b^2 = 17^2

225 + b^2 = 289

*-225 on both sides to get b by itself*

B^2 = 64

*to get rid of the ^2; you take the square root*

B = sqrt 64

B= 8 <— final answer

We can use the Pythagorean Theorem to solve for the missing side length (a).

Pythagorean Theorem:

a² + b² = c²

a and b are the legs (shorter sides) of the triangle and c is the hypotenuse (the longer side of the triangle).

1. Substitute in the known values.

a = ?

b = 15

c = 17

a² + 15² = 17²

2. Solve for a.

a² + 15² = 17²

a² + 225 = 289

a² + 225 - 225 = 289 - 225

a² = 64

√a² = √64

a = 8

the formula is:

[tex]a_n = \frac{n+1}{n+2}[/tex]

[tex]a_100 = \frac{101}{103}[\tex]

Answer:

see explanation

Step-by-step explanation:

We note that for each term, the numerator increases by 1 and the denominator increases by 1 from the previous term, that is

term 1 = [tex]\frac{1+1}{1+2}[/tex] = [tex]\frac{2}{3}[/tex]

term 2 = [tex]\frac{2+1}{2+2}[/tex] = [tex]\frac{3}{4}[/tex]

term 3 = [tex]\frac{3+1}{3+2}[/tex] = [tex]\frac{4}{5}[/tex]

-----------------------------------------------------------------------------

term 100 = [tex]\frac{100+1}{100+2}[/tex] = [tex]\frac{101}{102}[/tex]

If we let n be the term value, then the n th term is

[tex]a_{n}[/tex] = [tex]\frac{n+1}{n+2}[/tex]

Answer is “A”

Because since we know if we need to find the y is so we need to subtract 11-2.9=8.1

which mean y mean 8.1

The answer would be A

That is because you can not add unlike terms, so you would have to subtract 2.9 - 11 to find your answer. Therefore, the answer is 8.1

Step-by-step explanation:

Answer:

what

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

We know that the interior angle measures of a triangle are 180, and we are told that this is a right triangle.

Since we know the measure of two angles, we just have to do basic math:

180=90+70+x

solve for x (which equals 20) to get the measure of your acute angle

Final answer:

In a right triangle with one acute angle measuring 70 degrees, the measure of the other acute angle is 20 degrees, as the sum of all angles in a triangle is 180 degrees.

Explanation:

The sum of the angles in any triangle is always 180 degrees. In a right triangle, one of the angles is always 90 degrees, which is the angle that makes it "right." If a right triangle has one acute angle that measures 70 degrees, to find the measure of the other acute angle, we subtract the known angles from 180 degrees:

180 degrees (total in a triangle) - 90 degrees (right angle) - 70 degrees (given acute angle) = 20 degrees.

Therefore, the measure of the other acute angle in the triangle is 20 degrees.

Answer:

84 m^2

Step-by-step explanation:

We can break the polygon into a rectangle and a triangle

The rectangle at the bottom is 12 by 4

A = 12*4 = 48

The triangle at the top has a base of 12 and a height of (10-4) = 6

A = 1/2 (12) *6 = 36

The total is the sum of the two areas

A = 48+36 =84 m^2

100% + 20%= 120%

120% of $105.95

=6/5 × $105.95

A construction of the line plot for the length, in inches, of several nails is shown in the image attached below.

In Mathematics and Statistics, a line plot is a type of graph that is used for the graphical representation of data set above a number line, while using crosses, dots, or any other mathematical symbol.

In this scenario and exercise, we would make use of an online graphing calculator (tool) to graphically represent the given length (in yards) of several nails on a line plot as shown in the image attached below;

Length        Frequency

1/2                     2

5/16                   4

1/8                     2

3/8                     1

3/16                    1

In conclusion, we can reasonably infer and logically deduce that the mode of the data set is equal to 5/16 because it has the highest frequency of 4.

Complete Question;

This table shows the length, in inches, of several nails.

Length (in) 1/2, 5/16, 1/8, 1/2, 3/8, 5/16, 5/16, 3/16, 5/16, 1/8.

Simplifying the expression requires expanding the brackets, combining like terms, and applying algebraic rules including distribution. The resulting simplified form is – 35x2 + 8x – 8 after properly eliminating unnecessary terms and ensuring the solution is valid.

To simplify the expression 3x(x – 12x) + 3x2 – 2(x – 2)2, we need to apply standard algebraic techniques such as distribution, combining like terms, and simplifying polynomial expressions.

Firstly, distribute the 3x across the parentheses: 3x×(x – 12x) becomes 3x2 – 36x2.

Then, expand the square: – 2(x – 2)2 becomes – 2(x2 – 4x + 4).

Next, we can simplify the expression by combining like terms and further distributing where necessary:

Combine like terms:

Eliminate terms wherever possible and check to see if the simplified expression is reasonable. We are using multiplication, distribution, and combination of like terms to simplify the algebraic expression.

Answer: 3(x-4)

Step-by-step explanation:

Hii! Do you need to factor the expression 3x-12? No problem! (:

Note that both terms have something in common; it's known as the greatest common factor, or g.c.f.

The g.c.f. of 3x and -12 is 3, so we divide both 3x and -12 by 3.

We obtain

x-4

Now we put parentheses around x-4.

(x-4)

Next, we put 3 (the number we factored out) outside these parentheses.

3(x-4)
