Answer:
x=2 and y=6
Step-by-step explanation:
thee isn't any other way im sorry but there isn't here is a list:
1 nickel = $0.05 and 5 dimes =$0.50 = $0.55
2 nickels = $0.10 and 6 dimes = $0.60 = $0.70
3 nickels = $0.15 and 7 dimes = $0.75 = $0.85
4 nickels = $0.20 and 8 dimes = $0.80 = $1.00
5 nickels equal $0.25 and 9 dimes equals $0.90 = $1.15
so as you can see the more you add the higher the number gets and if its any lower it won't be enough sorry if you really needed that last part

If 3/5 of a cup of water fills 3/4 of a plastic container, how many containers could you fill with one cup of water?
Answer:
3/5 cup of water = 3/4 of container
1 cup of water = 3/4 * 5/3 of container
= 5/4 of container
Answer:
Step-by-step explanation:
ok so first you have to make equalt denominaters
3/5 = 12/20
3/4 = 15/20
so you can fill one and 3/20 with one full glass of water.

Which of these figures has rotational symmetry?
Rotational symmetry, also known as radial symmetry, is the quality that a form exhibits when it looks the same after a partial turn rotation. The correct option is D.
What is Rotational Symmetry?
Rotational symmetry, also known as radial symmetry, is the quality that a form exhibits when it looks the same after a partial turn rotation. The degree of rotational symmetry of an item is the number of possible orientations in which it appears precisely the same for each revolution.
Since for the rotational symmetry, the figure should look the same even if the figure is rotated. Thus, the figure that has a rotational symmetry is a rhombus. Hence, the correct option is D.

12+(8divided by 2/3)- 2
Answer:
22
Step-by-step explanation:
12+(8/(2/3)-2
22
Answer:
22
Step-by-step explanation:
First divide 8 by 2/3 ( since it’s in parentheses) and that gives you 12. Then add 12 + the 12 that was in parentheses. That leaves you with 24-2 which equals 22.
Set up an integral of the form
dc h2(y) h1(y) f(x,y) dx dy
for the volume of the region enclosed by the surfaces z = 2 - x2 - y2 and z = 2x + 2y. What is h2(0)+f(0,0)?
A. 5.
B. 13 + 2.
C. V2+1.
D. V3+1.
E. V2 + 2.
Answer:
Option D.
[tex]\mathbf{\sqrt{3}} +1}[/tex]
Step-by-step explanation:
The given integral is:
[tex]\int^d_c \int ^{h_2(y)}_{h_1(y)} f(x,y)\ dx \ dy[/tex]
The intersection curves enclosed by the surfaces:
z = 2 - x² - y² and z = 2x + 2y
This implies that:
[tex]2x +2y = 2 - x^2- y^2[/tex]
[tex](x^2 + 2x) +(y^2 + 2y) = 2 \\ \\ (x+1)^2 + (y + 1)^2 = 4 --- (1)[/tex]
We will realize that the curve of this intersection is a circle which is centered at (-1, -1) of the radius 2.
So, from equation (1)
[tex](x + 1)^2 = 4 - (y + 1)^2[/tex]
x + 1 = ±[tex]\sqrt{4 - (y + 1)^2}[/tex]
[tex]x = -1 \pm \sqrt{4 - (y+1)^2}[/tex]
Now,
[tex]h_2 (y) = -1 + \sqrt{4 - (y +1)^2}[/tex] and [tex]h_1 (y) = -1 - \sqrt{4 - (y +1)^2}[/tex]
[tex]h_2(0) = -1 + \sqrt{4-1}[/tex]
[tex]h_2(0) = -1 + \sqrt{3}[/tex], and:
[tex]At \ \ (-1, -1); \\ \\ z = 2 - (-1)^2 - (-1)^2 \\ \\ z = 2 - 1 - 1 \\ \\ z = 0[/tex]
and
[tex]z = 2x + 2y \\ \\ z = 2(-1) + 2 (-1) \\ \\ z = -2 + (-2) \\ \\ z = -4[/tex]
The surface z = 2-x²-y² lies above z = 2x + 2y in the region of intersection
∴
[tex]f(x,y) = (2 - x^2 - y^2) - (2x + 2y) \\ \\ f(0,0) = 2 - 0 \\ \\ f(0,0) = 2[/tex]
So, h₂ (0) + f(0,0) = [tex]\sqrt{3}} - 1 + 2[/tex]
h₂ (0) + f(0,0) = [tex]\mathbf{\sqrt{3}} +1}[/tex]

Determine any data values that are missing from the table, assuming that the data represent a linear function.
a. Missing x:13 Missing y:20
b. Missing x:13 Missing y:19
c. Missing x:11 Missing y:20
d. Missing x:11 Missing y:19
Answer:
d. Missing x:11 Missing y:19Step-by-step explanation:
It can be determined that the function is:
y = 0.5x + 12.5So missing x is:
18 = 0.5x + 12.5 ⇒ 0.5x = 5.5 ⇒ x = 11Missing y is:
y = 13*0.5 + 12.5 = 19Missing numbers are:
x= 11 and y = 19Correct choice is d.
FIRST METHOD
Answer:
Missing x = 11Missing y = 19Step-by-step explanation:
Given the table
x y
7 16
9 17
Missing x 18
13 Missing y
From the table, it is clear that y-values are incremented by 1 unit and the x-values are incremented by 2 units.
i.e.
y = 17-16 = 1
y = 18-17 = 1
as 19-18 = 1
Thus,
Thus, the value of Missing y = 19
also the x-values increment by 2.
i.e.
x = 9-7 = 2
as x = 11 - 9 = 2
Thus, Missing x = 11
Therefore,
Missing x = 11Missing y = 192ND METHOD
Given that the table represents a linear function, so the function is a straight line.
Taking two points
(7, 16)(9, 17)Finding the slope between (7, 16) and (9, 17)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(7,\:16\right),\:\left(x_2,\:y_2\right)=\left(9,\:17\right)[/tex]
[tex]m=\frac{17-16}{9-7}[/tex]
[tex]m=\frac{1}{2}[/tex]
Using the point-slope form to determine the linear equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 1/2 and the point (7, 16)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-16=\frac{1}{2}\left(x-7\right)[/tex]
Add 16 to both sides
[tex]y-16+16=\frac{1}{2}\left(x-7\right)+16[/tex]
[tex]y=\frac{1}{2}x+\frac{25}{2}[/tex]
Thus, the equation of the linear equation is:
[tex]y=\frac{1}{2}x+\frac{25}{2}[/tex]
Now substituting y = 18 in the equation
[tex]18=\frac{1}{2}x+\frac{25}{2}[/tex]
Switch sides
[tex]\frac{1}{2}x+\frac{25}{2}=18[/tex]
subtract 25/2 from both sides
[tex]\frac{1}{2}x+\frac{25}{2}-\frac{25}{2}=18-\frac{25}{2}[/tex]
[tex]\frac{1}{2}x=\frac{11}{2}[/tex]
[tex]x=11[/tex]
Thus, the value of missing x = 11 when y = 18
Now substituting x = 13 in the equation
[tex]y=\frac{1}{2}\left(13\right)+\frac{25}{2}[/tex]
[tex]y=\frac{13}{2}+\frac{25}{2}[/tex]
[tex]y=\frac{13+25}{2}[/tex]
[tex]y=\frac{38}{2}[/tex]
[tex]y = 19[/tex]
Thus, the value of missing y = 19 when x = 13
Hence, we conclude that:
The value of missing x = 11The value of missing y = 19Hence, option D is true.

Sara bought a pen at 25$ and sold it for $30. She then bought the same pen back at $35 and sold it again for $40. Did she make or lose money from these two deals in the end.
Answer:
honestly if u ask me ima have to say she lost some money cause
Step-by-step explanation:
she got it for 25 right then she got an exstra 5 dollars cause she sold it
for 30 then she got the same pen for 35 when she got it for 25 the first time so 25-35 = 10 meaning she lost 10 dollars and got 10 dollars back because if u add the 5 dollars from the 30 then from the 40 u get ten meaning
she just got her money right back

Any help is appreciated
Answer:
[tex]64a^{3} b^{6}[/tex]
Step-by-step explanation:
1) Distribute the exponent outside of the parentheses to the terms inside the parentheses. In this case, multiply the 3 outside the parentheses with the exponent of each of the terms inside:
[tex](4ab^{2} )^3[/tex]
[tex]4^{3}[/tex] · [tex]a^{3}[/tex] · [tex]b^{6}[/tex]
2) The variables are fine - you can't simplify them further. All you need to do now is multiply the [tex]4^{3}[/tex] out. Remember that it's kind of like asking, "what is 4 × 4 ×4?"
[tex]4[/tex] · [tex]4[/tex] · [tex]4[/tex] · [tex]a^{3}[/tex] · [tex]b^{6}[/tex]
[tex]16[/tex] · [tex]4[/tex] · [tex]a^{3}[/tex] · [tex]b^{6}[/tex]
[tex]64a^{3} b^{6}[/tex]
Therefore, [tex]64a^{3} b^{6}[/tex] is the answer.
There are 4 quarts in 1 gallon. A restaurant orders 112 quarts of milk to use 3 points as an ingredient in holiday baking. How many gallons of milk did they order?
Answer:
The restaurant ordered 28 gallons of milk.
Step-by-step explanation:
We have 4 quarts in 1 gallon:
[tex] \frac{1 G}{4 Q} [/tex]
Since the restaurant orders 112 quarts we have:
[tex] \frac{1 G}{4 Q}*112 Q = 28 G [/tex]
Hence, the restaurant ordered 28 gallons of milk.

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks. Today's cafeteria specials at a high school in Ashland are a deluxe turkey sandwich and a chef salad. During early lunch, the cafeteria sold 14 turkey sandwiches and 61 chef salads, for a total of $150. During the late lunch, 14 turkey sandwiches and 25 chef salads were sold, for a total of $78. How much does each item cost? A turkey sandwich costs $ , and a chef salad costs $ .
Answer:
Equation 1: 14t + 61s = 150
Equation 2: 14t + 25s = 78
Use Elimination (x)
(-1) (14t + 25s) = (78) (-1)
-14t - 25s = -78
14t + 61s = 150
+ -14t - 25s = -78
--------------------------
36s = 72
s = 2
Salad costs $2
Then find t
14t + 61(2) = 150
14t + 122 = 150
14t = 28
t = 2
Sandwich costs $2
