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]
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.

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.

find the value of X in the triangle
Two sides of the triangle are the same length, so the two angles of the long side are identical.
The three inside angles total 180, so the sum of the 2 identical angles would equal: 180-70 = 110
x is one of those angles. X = 110/2 = 55 degrees.
X = 55
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

On holidays three friends decided to buy a Christmas tree for $96. They made a cash contribution of 3: 5: 8. The two friends who invested less decided to return the third friend's money so that their cash contributions became the same. What is the ratio of the money returned by the first person to the money returned by the second person
Answer: 7:1
Step-by-step explanation:
First off, we see that the contribution was divided into 16 parts (8+5+3). If the tree was $96, 96/16 = $6, so each individual part was $6.
First Person: 3(6) = $18
Second Person: 5(6) = $30
Third Person: 8(6) = $48
We know that after the two friends return the money, the $96 will have been split evenly between all three of them.
96/3 = 32 - each person pays $32 total
Because each person has to pay $32 total, the first person must return $14 and the second person must return $2. This means that the ratio is 14:2 which can be reduced to 7:1.
Person 1: 32-18 = 14
Person 2: 32-30 = 2
Person 3: 48-14-2 = 32. - check to see if we were correct, which we are because after two friends pay 3rd back, their total is also 32 dollars.

uses a combined length of 1,000 yards of
wire. What length of tie wire was used?
Help me
9514 1404 393
Answer:
500 ft or 166 2/3 yards
Step-by-step explanation:
The tie wire is (100)/(100 +500) = 1/6 of the total length of wire used. If 1000 yards of wire is used, 1/6 of that amount can be expected to be tie wire. That is ...
(1000 yd)/6 = 166 2/3 yd = 500 ft
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

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.
