What the meaning of statement this?

The surface area of the cylinder is 905 square centimeters

From the question, we have the following parameters that can be used in our computation:

Diameter, d = 12 cm

Height, h = 18 m

This means that

Radius, r = 12/2 = 6 cm

Using the above as a guide, we have the following:

Surface area = 2πr(r + h)

Substitute the known values in the above equation, so, we have the following representation

Surface area = 2π * 6 * (6 + 18)

Evaluate

Surface area = 905

Hence, the surface area is 905 square centimeters

Answer: B 18oz

Step-by-step explanation:

You would compare how much each jar costs per oz

Unit = [tex]\frac{cost}{oz}[/tex]

The above tells you to divide cost by oz

12 oz :    $3.00/12 oz     = $.25 / oz

18 oz:   $4.40/18 oz      = $.24 / oz

25 oz:    $6.75/25 oz    = $.27 / oz

32 oz:   $8.25/32 oz     = $.26 / oz

Answer:  18 oz is cheapest per oz

It should be noted that triangle ABC is an isosceles triangle.

An isosceles triangle has two sides of equal length, and the third side is longer than the other two sides. In triangle ABC, AB = DCE, which means that sides AB and DCE are equal in length. The third side, AC, is longer than AB and DCE, because ABC = 80, which is greater than 50.

The two angles opposite the equal sides are also equal. In triangle ABC, angles A and C are equal because sides AB and AC are equal.

The altitude (a line drawn from a vertex perpendicular to the opposite side) bisects the opposite side. In triangle ABC, the altitude from vertex A bisects side BC.

Answer:

C. (-2,0)  **See diagram**

Step-by-step explanation:

For a coordinate system, the origin is the point located at (0,0).

Any coordinate ordered pair (x,y) is given with the x-coordinate (the "left-right" distance from the origin) first, and the y-coordinate (the "up-down" distance from the origin) second.

With the given starting point (-6,3), the original point is to the left (in the negative "x" direction) 6 units, and up (in the positive "y" direction) 3 units.

the y-coordinate

To translate (slide or move) the point down 3 units would affect the y-value by subtracting 3.  The original y-value is 3, so subtracting 3 will give a new y-value result of 0.

the x-coordinate

To translate the point right 4 units would affect the x-value by adding 4.  The original x-value is -6, and we need to add 4.

Adding positive and negative numbers

When adding two numbers where one is positive and one is negative, we'll want to look at the magnitude ("size," or distance from zero) of the two numbers.  Negative six is 6 units from zero, and positive four is 4 units from zero.

When adding one positive and one negative number, the result has a sign matching the number with the larger magnitude, and a value that is the difference of their two magnitudes.

The negative six is the larger number, so the result will be negative.

The difference between 4 and 6 is 2 (counting from 4 up to 6 takes two steps... or differently, six minus four is two).

So adding 4 to -6 will give a new x-value result of -2.

Hence, the final point (as illustrated in the diagram), is (-2,0), which is answer choice C.

Carrie has 4 more pints of paint than Bryan.

Carrie has 3 gallons of paint, which is equivalent to 12 quarts (1 gallon = 4 quarts). On the other hand, Bryan has 10 quarts of paint.

To compare the quantities in the same unit, we note that 1 quart is equal to 2 pints.

Carrie's 12 quarts of paint is equivalent to 12 × 2 = 24 pints.

Bryan's 10 quarts is equivalent to 10 × 2 = 20 pints.

To find the difference, we subtract Bryan's pint quantity from Carrie's:

24 - 20 = 4 pints.

Therefore, Carrie has 4 more pints of paint than Bryan.

The area of a triangle is given by the formula 1/2 * base * height. Substituting the given values for the base and height into this formula, we get:

1/2 * √63 * √28 = 1/2 * 7√9 * 2√7 = 7 * √9 * √7 = 21√7 cm^2

So the area of the triangle is 21√7 cm^2.

Answer:

To find the angle of elevation, we can use the inverse tangent function (arctan). The angle of elevation is the angle between the ground and the line of sight from the ground to the top of the ladder.

Let's calculate it:

Angle of elevation = arctan(opposite/adjacent)

Angle of elevation = arctan(15 feet / 18 feet)

Using a calculator or table of trigonometric functions, we can find the arctan of (15/18) to be approximately 41.19 degrees.

Rounded to the nearest degree, the angle of elevation from the ground to the top of the ladder is 41 degrees.

Step-by-step explanation:

The probability of a family with 4 people will be 0.244.

Here, we have,

A survey found the distribution of some families by size and is as follows:

Family Size 2 3 4 5 6 7 8

Frequency 87 50 61 31 16 3 2

The probability is given as,

P = (Favorable event) / (Total event)

The probability of a family with 4 people is calculated as,

P = (61) / (87 + 50 + 61 + 31 + 16 + 3 + 2)

P = 61 / 250

P = 0.244

Hence, The probability of a family with 4 people will be 0.244.

Answer:

If two linear functions have the same coefficients of x, then the graphs of the two linear functions do not intersect at exactly one point.

Step-by-step explanation:

The statement that is logically equivalent to q→ p is:

If two linear functions have the same coefficients of x, then the graphs of the two linear functions do not intersect at exactly one point.

This is because the contrapositive of an implication is logically equivalent to the original implication. The contrapositive of q→ p is ¬p→ ¬q, which means:

If two linear functions do not have different coefficients of x, then the graphs of the two functions do not intersect at exactly one point.

Simplifying this statement, we get:

If two linear functions have the same coefficients of x, then the graphs of the two linear functions do not intersect at exactly one point.

Another way to write the mixed number 2 4/12 is 2 1/3.

Another way to represent the shaded portions that model the mixed number 2 4/12 is by simplifying the fraction to its simplest form.

In this case, 4/12 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 4. By simplifying, we get 1/3. Thus, the mixed number 2 4/12 can be expressed as 2 1/3.

This representation implies that there are two whole units (2) and an additional fractional part equivalent to one-third (1/3) of a unit. It provides a clearer and more concise representation of the same quantity, avoiding unnecessary complexity.

The speed of the radius changing at the instance the radius is 4 feet is 0. 72 ft per second.

Given that the balloon is inflating at the rate of 144 cubic feet per second :

dV  / dt = 144 cubic feet/second.

The volume equation of a sphere would need to be differentiated as a result to find the rate at which the radius of the balloon is changing:

dV/ dt = d / dt [4/3 x π x r ³ ]

dV/ dt = 4π x r²  x dr / dt

144 = 4 π x (4)² x dr / dt

144 = 64 π x dr / dt

Based on the dot plots, it appears that students generally did more push-ups this year than last year.

The range of the push-ups completed this year is 12, while the range of the push-ups completed last year is only 10.

This means that there is a greater spread of values in the data set for this year, with some students completing many more push-ups than others. In the data set for last year, the values are more evenly distributed, with most students completing between 5 and 10 push-ups.

The range of a data set affects the shape of the dot plot by determining how spread out the values are. A wide range will result in a dot plot that is more spread out, while a narrow range will result in a dot plot that is more compact. In the case of the push-up data, the wider range of values for this year results in a dot plot that is more spread out than the dot plot for last year.

Answer:

x = 12, y = -1

Step-by-step explanation:

x - 2y = 14            (call this equation '1.')

x + 3y = 9             (call this '2')

'2' - '1' :

0x  + (3 - -2)y = 9 -14

(3 + 2)y = -5

5y = -5

y = -1.

substitute than into '1':

x - 2(-1) = 14

x + 2 = 14

x = 12.

check we are correct by subbing into '2'.

x + 3y = 9

12 + 3(-1) = 12 - 3 =9

so, x= 12 and y = -1

Answer:

X=14+2y

14+2y+3y=9
