What is the volume of the cone pictured? (Use 3.14 for pi)

Answer:

20%

Step-by-step explanation:

Step 1: Subtract starting value minus the final value (decrease)

[tex]\$5.75 - \$4.60\\\\= 5.75 - 4.60 \\\\= 1.15[/tex]

Step 2: Divide the decrease by the original number

[tex]1.15 \div 5.75\\\\= \frac{1.15}{5.75}\\\\= 0.2[/tex]

Step 3: Multiply the result by 100 to get a percent decrease

[tex]0.2 \times 100\\\\= 20[/tex]

Therefore, the percent decrease of the price of paper per package is 20%

Note: If the percentage is negative, it means there was an increase and not a decrease.

Since the lengths EH and FG have the identical slope ratios as the parallel lines problem that is being given, assertion 4 is true, and so statement 4 is: EHFG.

Two non-vertical lines with the same slope that are located in the same plane are said to be parallel. Two parallel lines cannot cross each other. Right angles connections are those that intersect two non-vertical line in the same plane at a right angle.

Here,

The slope values in EH and FG are the same.

This implies that they follow one another in a straight line.

Since the sections EH and FG share the same gradient values as the parallel lines problem that is being given, assertion 4 is true, and so statement 4 is: EH||FG.

Answer:

for the first picture, the answer is A

Step-by-step explanation:

this is because it moves up 4, and 2 to the right, which means if it was to move 2 up, it will move 1 to the right. y - 2x, when you put it into y-intercept form, the equation will be y = 2x. which matches the points on the graph.

Answer: A. y = 2x

Step-by-step explanation: You can figure out the relationship between the x and y coordinates on the graph by imagining a line that runs through the given points and then figuring out the equation of the line in slope-intercept form by following the format of y=mx+b. "y" represents the output, "m" represents the slope (vertical change compared to the horizontal change), "x" represents the input, and "b" represents the y-intercept (where the line crosses the y-axis). Since the line is increasing, the slope is going to be positive. To get from the point at (0, 0) to the point at (2, 4), you go 4 units up and 2 units to the right; therefore, the value of "m" (slope) is 2, which is just  the simplified version of 4/2. Since the line crosses the y-axis at (0, 0), the value of "b" is 0. With this information, the slope-intercept equation is y=2x+0. You can disregard the 0 in the equation since it does not have any affect on the graph since it holds no value. Now, the final equation is y=2x.

Answer:

Y = 7.60X + 1246.67

Step-by-step explanation:

Given the data:

Production Volume (units) Total Cost ($)

400 4000

450 5000

550 5400

600 5900

700 6400

750 7000

Using technology, the linear regression calculator, the regression model obtained by fitting the data is :

Y = 7.60X + 1246.67 ; which is the model giving the relationship between Production volume, x and total cost, y.

Slope = 7.60

Intercept = 1246.67

Answer:

{ 8, 2}

Step-by-step explanation:

Basic algebra, the object which is not in a set quantity, which we have to find, is the "some vans" and the "some buses"

So let the number of van be x

Let the number of buses be y

So, since there are 10 vehicles,

x+y=10

Makes sense right

Now, it says that every car can carry 6 students, and every van can carry 35 students, so in another way, we could represent this by saying

6 x Number of van + 35 x Number of buses

thus,

6x + 35y

And since 118 students went on the field trip, this means that

6x +35y = 118

So now we have two equations,

x + y = 10

6x + 35y = 118

We can solve this with substitution

x + y = 10

x = 10 - y

Thus, x = 10-y

Put this in this

6(10-y)+ 35y= 118

60-6y+35y=118

60+29y=118

29y=118-60

29y= 58

y = 58/29

y = 2

Thus, the number of buses, y, is 2

Now since there are 10 vehicles, and 2 are buses, then the other are 8 van

There are 9 full cases and 2 additional items are needed to fulfill the order 56 items ordered 6 items per case.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

56 items ordered for 6 items per case.

Now, After divide the quotient shows the number of full case and remainder shows the additional items.

Hence, We get;

 6 ) 56 ( 9

      54

   ---------

        2

Thus, There are 9 full cases and 2 additional items are needed to fulfill the order 56 items ordered 6 items per case.

The graph of an inequality in two variables is the set of points that represents all solutions to the inequality.

The boundary line that separates the coordinate plane into two halves by a linear inequality represents the solutions to the inequality in one half. For > and, the border line is solid, and for and, it is dashed.

To determine the equation governing the inequality line, enter your slope and a point into the formula y = mx + B, where "m" denotes the slope, "x, y" denotes a point on the line, and "b" is the y-intercept. By inserting (0, 0), you get 0 = 0 + b, which equals 0.

When you rewrite the equation, you get y = x/2. The linear inequality x - 5 > 3x - 10 is an illustration. Due to the greater than symbol being utilised in this inequality, the LHS is clearly greater than the RHS.

When the cross-section of a wall is 7/16 of an inch thick and the drywall is 1/4 inches thick, the thickness of the texturing on wall is A. 3/16

A fraction simply means a piece of a whole. In this situation, the number is represented as a quotient such that the numerator and denominator are split. In this situation, in a simple fraction, the numerator as well as the denominator are both integers.

From the information, the cross-section of a wall is 7/16 of an inch thick. If the drywall is 1/4 inches thick. The thickness of the texturing on the wall is the total thickness of the wall minus the thickness of the drywall. The total thickness of the wall is 7/16 inches, and the thickness of the drywall is 1/4 inches, so the thickness of the texturing is:

= 7/16 inches - 1/4 inches

= 3/16 inches.

The volume of the parallelopiped is 14 cubic units

The volume of a parallelopiped with vector sides a, b and c is given by

V = (a × b).c

We know that the parallelopiped has sides

Thus, we proceed as follows

(a × b) = (2, 1, 0) × (3, -1, 2) = (2 × 3)i × i + (2 × -1)i × j + (2 × 2)i × k + (1 × 3)j × i + (1 × -1)j × j + (1 × 2)j × k + (0 × 3)k × i + (0 × -1)k × j + (0 × 2)k × k

Since

So, we have

(a × b) = (2, 1, 0) × (3, -1, 2) = (6) × 0 + (-2)k + -(4)j + 3i + (-1) × 0 + (2)i + -(3)j + -(0)i + (0) × 0

= 0 -2k - 4j + 3i + 2i - 3j - 0 + 0

= 5i  -7j - 2k

= (5, -7, -2)

Since (a × b) = (5, -7, -2)

Thus, the volume of the parallelopiped is

V = (a × b).c

= (5, -7, -2).(4, 0, 3)

= 5 × 4 + (-7 × 0) + (-2 × 3)

= 20 - 0 - 6

= 14

So, the volume is 14 cubic units

From the classification angles, it was possible to find the arcs:

UL=40, UY= 90, TY=50, YLE =270, LE=140 and UET=220.

If UE= 180 and TE=40, you have:

UET=UE+TE

UET=180+40

UET=220

They are a lot of classifications for angles like complementary angles, supplementary angles, right angles, and others. See below:

The question gives mTE=40, and it asks:

UL is opposite the arc TE, therefore its value is also 40.

The figure shows a right angle, then UY is equal to 90.

If UY is equal 90, YE is equal to 90 too, because they are supplementary. If YE=90 and TE=40, you have:

TE+TY=90

40+TY=90

TY=90-40

TY=50

YLE = YE+UE. The figure shows YE=90 and UE represents a semicircle (180). Thus,

YLE= 90+180=270

If UE= 180 and UL=40, you have:

UE=UL+LE

180=40+LE

LE=180-40

LE=140

If UE= 180 and TE=40, you have:

UET=UE+TE

UET=180+40

UET=220

40% of an hour is 24 minutes = 2/5 hours.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

Given that,

there are 60 minutes in an hour,

we can multiply this by 0.4 to find that 24 minutes constitutes 40% of an hour.

i.e. 60*40%= 24 minutes

Hence, 40% of an hour is 24 minutes = 2/5 hours.
