Answer:

Option A - [tex]26 \mathrm{cm}^{3}[/tex]

Step-by-step explanation:

Given: The volume of a cylinder = [tex]78 \mathrm{cm}^{3}[/tex]

Let us substitute the volume of cylinder in the formula.

The formula for volume of a cone is [tex]V=\frac{\pi r^{2} h}{3}[/tex]                    (1)

The formula for volume of a cylinder is [tex]V=\pi r^{2} h[/tex]              (2)

Substituting [tex]V=78[/tex] in equation (2), we get,

[tex]\begin{array}{c}{V=\pi r^{2} h} \\{78=\pi r^{2} h}\end{array}[/tex]

Given that the cone has the same radius and height of that of the cylinder, let us substitute [tex]78=\pi r^{2} h[/tex] in equation (1)

[tex]\begin{array}{l}{V=\frac{\pi r^{2} h}{3}} \\{V=\frac{78}{3}} \\{V=26}\end{array}[/tex]

Thus, the volume of a cone with the same radius and height of a cylinder is [tex]26 \mathrm{cm}^{3}[/tex].

The volume of the cone is 26 cubic centimeters.

A cylinder has a volume of [tex]78 \;\rm{cm}^3[/tex].

We need to determine the volume of a cone with the same dimensions compared to a cylinder.

Now,

The formula for finding the volume of the cylinder is [tex]\pi r^2h[/tex].

The formula for finding the volume of the cone is [tex]\dfrac{1}{3}\pi r^2h[/tex].

Therefore, the volume of the cylinder is thrice the volume of the cone if we consider the same dimensions.

Thus,

[tex]\begin{aligned} 3 \times \rm{volume\;of\;the\;cone}&=78\;\rm{cm^3}\\&=26\;\rm{cm^3} \end{aligned}[/tex]

Hence, the volume of the cone is 26 cubic centimeters.

Answer:

x = 2,  y = 3

Step-by-step explanation:

i) It is given that 5x - 3y =1

ii) It is also given that x = 2y - 4

iii) we can substitute the value of x from ii) in the equation in i) and we will get 5(2y - 4) - 3y = 1   ⇒ 10y - 20 -3y =  1   ⇒  7y = 21  ∴ y = 3

iv) substituting the value of y obtained in ii) we get x = (2 × 3) - 4 = 6 - 4 = 2.

v) Therefore x = 2.

Step-by-step explanation:

Given: Television advertising= $38 out of every $100 spent on advertising.

           Radio advertising= 21% as much as was spent on television ads.

As given there are $38 spent on television ads on every $100 of advertising.

∴ Amount spent on television ads= [tex]\frac{38}{100}[/tex]

Now, finding amount spent on radio advertising on every $100 spent on advertising.

We know, The amount spent on radio advertising was about 21% as much as was spent on television advertising.

∴ Amount spent on radio advertising= [tex]\frac{38}{100} \times \frac{21}{100}[/tex]

⇒ Amount spent on radio advertising= [tex]\$ 0.0798[/tex]

To know the amount spent on radio advertising on every $100 spending on advertising.

Amount spent on Radio advertising on every $100 spending= [tex]0.0798\times 100= \$ 7.98 \approx \$ 8[/tex]

Hence, $8 spent on radio advertising on every $100 spending.

About $7.98 out of every $100 spent on advertising was allocated to radio advertising, based on the information that $38 out of every $100 was used for television advertising and radio advertising accounted for 21% of the television advertising amount.

In 2004, about $38 out of every $100 spent on advertising was spent on television advertising. To find out how much of every $100 was spent on radio advertising, which was about 21% as much as was spent on television advertising, we apply the following calculation:

Amount spent on radio advertising = Television advertising amount × (Radio advertising percentage / 100)

Amount spent on radio advertising = $38 × (21 / 100)

Amount spent on radio advertising = $7.98

Therefore, $7.98 out of every $100 spent on advertising was spent on radio advertising.

Use the distance formula Sqrt ( (x2-x1)^2 +(y2-y1)^2)

Distance = sqrt ( (-8 - -2)^2 +(4- -4)^2)

Distance = sqrt(-6^2 + 8^2)

Answer:

7 and 6

are the alternate interior angles.

Answer:

Explanation:

By inspection (watching the figure), you can tell that to transform the triangle XY onto triangle X"Y"Z", you must slide the former 5 units to the left, 1 unit down, and, finally, reflect it across the x-axys.

You can check that analitically

Departing from the triangle: XYZ

Thus, in conclusion, it is proved that the sequence of transformations that maps triangle XYZ onto triangle X"Y"Z" is translation 5 units to the left, followed by translation 1 unit down, and relfection accross the x-axis.

First subtract 3: u/5 = -2

Now, because u is divided by 5, we can multiply by 5 to get u on its own.

u = -10

To check, -10/5 + 3 = 1

-2 + 3 = 1

1 = 1

This leaves us with a true statement, so the answer is correct.

Answer:

the given statement is true.

Step-by-step explanation:

i) It is given that the base angles of an isosceles triangle each measure 37°.

ii) Adding the values of the base angles is = 37° + 37° = 74°

iii) from the property of triangles we know that the sum of all the angles in a triangle is equal to 180°

iv) let the vertex angle be = y°

v) Therefore we can say from ii), iii) and iv) above that

      74° + y° = 180°

vi) therefore the vertex angle y = 180° - 74° = 106°

Hence the given statement is true.

Answer: [tex]\theta\approx1.78\ rad[/tex]

Step-by-step explanation:

By definition, the Arc lenght can be calculated with the following formula:

[tex]s=r\theta[/tex]

Where "s" is the Arc lenght, "r" is the radius and [tex]\theta[/tex] is the central angle measured in radians.

From that equation you can solve for [tex]\theta[/tex] dividing both sides of the equation by the radius "r", then:

[tex]\frac{s}{r}=\frac{r\theta}{r}\\\\\theta=\frac{s}{r}[/tex]

According to the information given in the exercise:

[tex]s=21.3\ in[/tex]

And you can identify in the figure that the radius of the circle is:

[tex]r=12\ in[/tex]

Therefore, you can substitute values into the equation:

[tex]\theta=\frac{21.3\ in}{12\ in}[/tex]

Finally, evaluating, you get the following result:

[tex]\theta=1.775\ rad[/tex]

Rounded to the nearest hundredth of a radian:

[tex]\theta\approx1.78\ rad[/tex]

Answer:

A) 40

B) $ 15

Step-by-step explanation:

A)An equation for the number of​ 30-day periods until the value of the gift cards will be equal

Let x be the number of time periods for which the gift card is not used, then

For the gift card $ 155 if it is not used for x periods, then the amount that will be lost is

155 - 3.50 x---------------------(1)

For the gift card $ 135 if it is not used for x periods, then the amount that will be lost is

135 - 3x---------------------- (2)

Now when both the amount lost is equal

[tex]155 - 3.50x = 135 - 3x[/tex]

solving the equation, we get

[tex]155 -135 = -3x + 3.50x[/tex]

20 =  0.5x

[tex]x = \frac{20}{0.5}[/tex]

x = 40

Thus the value of gift cards will be equal for 40 ,30 day periods.

B)The value of each card be when they have equal​ value

The two cards  will have equal value after 40 30 day periods, this denotes that at this time, the value of each card will be equal.

Then

[tex]155 - 3.50x = 135 - 3x[/tex]

substituting  x = 40, we get

[tex]155 - 3.50(40)= 135 - 3(40)[/tex]

[tex]155 - 140= 135 - 120[/tex]

[tex]15 =15[/tex]

when they have equal​ value, the value of each card will be $15

Answer:

[tex]\frac{1}{2}[/tex] quart

Step-by-step explanation:

Given:

Riley drink 4/5 quart of iced tea

And her friend drink 0 3/10 quart of iced tea

Question asked:

how much more of a quart of iced tea did Riley drink than her friend = ?

Solution:

Riley drank of iced tea = [tex]\frac{4}{5}[/tex]

Her friend drank of iced tea = [tex]0\frac{3}{10}[/tex]

                                                = [tex]\frac{3}{10}[/tex]

We will subtract the share of her friend from Riley's share

Riley drank more than her friend =[tex]\frac{4}{5} - \frac{3}{10}[/tex]  

                                                     = [tex]\frac{5}{10}[/tex]

                                                     =    [tex]\frac{1}{2}[/tex]

Thus, Riley drank [tex]\frac{1}{2}[/tex]  quart more than her friend.

Final answer:

Riley drank 1/2 quart more iced tea than her friend, which is the difference between 4/5 quart and 3/10 quart.

Explanation:

The question asks how much more of a quart of iced tea did Riley drink than her friend. Riley drank 4/5 quart and her friend drank 3/10 quart. To find out the difference, we subtract the smaller amount from the larger amount:

4/5 quart - 3/10 quart = 8/10 quart - 3/10 quart = 5/10 quart or 1/2 quart.

Therefore, Riley drank 1/2 quart more iced tea than her friend.

Step-by-step explanation:

The correct option that is not a characteristic of all parallelograms is C, 'diagonals are angle bisectors,' as it does not apply to every parallelogram, unlike the other options listed.

The question is related to the properties of parallelograms, and specifically, it asks which option is not a characteristic of all parallelograms. To answer this, we must review the properties of parallelograms:

Option A (Diagonals bisect each other) and Option B (Opposite angles are congruent) are indeed true characteristics of parallelograms. However, diagonals being angle bisectors is not a general characteristic of all parallelograms, making it incorrect for Option C. Finally, Option D (The sides are congruent) describes a property specific to a rectangle or a rhombus rather than all parallelograms. Thus the correct answer is C, diagonals are angle bisectors, as it is not a defining feature for all parallelograms. Parallelograms have diverse shapes like rectangles, squares, and rhombi, and this property doesn't apply universally.

a. function A has a slope of -2/3. the negative means it goes down. function B is going down on the graph so both functions have neg. rates of change.

b. function A's slope is -2/3. function b has a slope of -1.

c. since both functions slopes aren't the same they are not parallel.

d. 2/3 is a lesser rate of change than 1.

e. looking at the graph, function b is linear. A is linear since the "x" is not squared, cubed, etc.

Answer:

0.0025

Step-by-step explanation:

:)

1/4 of 1%, when expressed as a decimal, is equal to 0.0025

A percentage is a ratio with the second part always equal to 100. It represents parts per hundred.

We have been given 1%.

We replace percentage in fraction, and then fraction to decimal.

1% = 1/100 = 0.01

Now, we need to calculate 1/4th of this value, that is, 0.25 multiplied by the above value,

= 0.25 * 0.01 = 0.0025
