Answer:
6
Step-by-step explanation:
16/4=4 (to brother) 16-4=12 (whats remaining) 12/2=6 (to sister)
Ruby gives her sister 6 animals.
Explanation:To find out how many animals Ruby gives her sister, we need to follow the instructions step by step. Ruby starts with 16 stuffed animals. She gives 1/4 of her collection to her brother, which is equal to 16 * 1/4 = 4. Now Ruby has 16 - 4 = 12 stuffed animals left. Then she gives half of the remaining animals to her sister, which is equal to 12 * 1/2 = 6. So Ruby gives her sister 6 animals.
Riley drink 4/5 quart of iced tea and her friend drink 0 3/10 quart how much more of a quart of iced tea did Riley drink than her friend
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.

Describe the sequence of transformations that maps triangle XYZ onto triangle X”Y”Z”.
Answer:
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.
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
Translation 5 units to the left: (x,y) → (x - 5, y) Vertex X: (-6,2) → (-6 - 5, 2) = (-11,2)Vertex Y: (-4, 7) → (-4 - 5, 7) = (-9,7)Vertex Z: (-2, 2) → (-2 -5, 2) = (-7, 2)Translation 1 unit down: (x,y) → (x, y-1)
(-11,2) → (-11, 2 - 1) = (-11, 1)(-9,7) → (-9, 7 - 1) = (-9, 6)(-7, 2) → (-7, 2 - 1) = (-7, 1)Reflextion accross the x-axis: (x,y) → (x, -y)
(-11, 1) → (-11, -1), which are the coordinates of vertex X"(-9, 6) → (-9, -6), which are the coordinates of vertex Y""(-7, 1) → (-7, -1), which are the coordinates of vertex Z"
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.
If 5x - 3y = 1 and x = 2y - 4, then x • y = ?
I don’t need an explanation of the answer since it’s multiple choice, but feel free to give an explanation if you want :) thank you and please answer quickly this is due tomorrow!!
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.
how to solve u/5+3=1
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.
If the arc length shown in blue is 21.3 inches, then 0 to the nearest hundredth of a
radian is
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]

A cylinder has volume 78 cm3 . What is the volume of a cone with the same radius and height? A 26 cm3 B 39 cm3 C 156 cm3 D 234 cm3
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.

In 2004, about $38 out of every $100 spent on advertising was spent on television advertising. The amount spent on radio advertising was about 21% as much as was spent on television advertising. How much of every $100 spent on advertising was spent on radio advertising?
Answer:
$8
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.

If the base angles of an isosceles triangle each measure 37° then the vertex angle measures 106°
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.

Tavon has a gift card for $ 155 that loses $ 3.50 for each 30-day period it is not used. He has another gift card for $ 135 that loses $ 3 for each 30-day period it is not used.
a. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal.
b. What will the value of each card be when they have equal value?
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

what of the following is not a characteristic of all parallelograms diagonals bisect each other be opposite angles are congruent C diagonals are angle bisectors deep is the sides are congruent
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.
Explanation: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:
Diagonals bisect each other.Opposite angles are congruent.The sides are parallel, but not necessarily congruent.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.
