Answer:
X is 160. because you can add all the value of x. But first substrate 540 with 100 which is 440. then 1/2x + 1/2x+ (x-15) + (x-25) which is further simplified as x + 2x - 40. then it's further simplified as 3x - 40 = 440. then add 40 with 440 which is 480 then divide it by 3 which is 160. therefore X= 160.
Find the value of the angle θ rounded to 1 DP.
The diagram is not drawn accurately.
The measure of the indicated angle θ is approximately 39.9°.
Use the concept of a triangle defined as:
A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.
After labeling the figure
In triangle ABC
Sin θ = AC/AB
Sin 26° = AC/19
AC ≈ 0.44 x 19
AC ≈ 8.36
Now in Triangle ADC,
tan θ = (opposite side of θ)/(Adjacent side)
tan θ ≈ 7/8.36
tan θ ≈ 0.837
Take the inverse of tan on both sides, we get,
θ ≈ 39.9°
Hence,
The value of angle θ is approximately 39.9°.

A pet store has three fish tanks, each holding a different volume of water and a different number of fish.
Tank A holds 40 L and 5 fish. Tank B holds 100 L and 12 fish. Tank holds 180 L and 23 fish,
Order the tanks by volume per fish from least to greatest
For each tank just divide the number of L by the number of fish to get the volume or fish.
For tank A it is 40/5=8, for tank B it is 100/12=8.3, and for tank C it is 180/23=7.8.
If you number them least to greatest, it is (tank C, tank A, tank B)

What is the instantaneous slope of y = eight over x at x = -3?
A. -8/3
B. 8/3
C. -8/9
D. 8/9
Answer:
C
Step-by-step explanation:
[tex]\frac{d}{dx} (8x^-1)\\-8x^{-2}\\[/tex]
using x = -3
[tex]-8(-3)^{-2}\\\frac{-8}{9}[/tex]
The instantaneous slope of the function y = 8/x at x = -3 is -8/9.
Option C is the correct answer.
We have,
To find the instantaneous slope of the function y = 8/x at x = -3, we can differentiate the function with respect to x.
Differentiating y = 8/x using the power rule, we get:
dy/dx = -8/x²
Now, we can evaluate the instantaneous slope at x = -3 by substituting the value into the derivative:
dy/dx = -8/(-3)²
= -8/9
Therefore,
The instantaneous slope of the function y = 8/x at x = -3 is -8/9.

If you divide a negative by a negative, then it equals a positive, because the two negatives cancel out.
So, -15/-5 = 3.

Average movie in the Uruled States gerveral . Cost tickets in Japan plus two tickets in Switzerlandtickets in Switzerland plus two tickets in Japan would cost \$/5.27 . How much does an average movie ticket cost in each of these countries in Japan the average costis Switzerland the average cost is $
Answer:
The average cost of a movie ticket in Japan is $17.86 and the average cost of a movie ticket in Switzerland is $13.75
Step-by-step explanation:
The question seems to be incomplete. Here is a similar question and the solution:
Average movie prices in the United States are, in general, lower than in other countries. It would cost $81.08 to buy three tickets in Japan plus two tickets in Switzerland. Three tickets in Switzerland plus two tickets in Japan would cost $76.97. How much does an average movie ticket cost in each of these countries?
Step-by-step explanation:
Let the cost of tickets in Japan be $x and the cost of tickets in Switzerland be $y.
From the question,
It would cost $81.08 to buy three tickets in Japan plus two tickets in Switzerland. That is
3x + 2y = 81.08 ...... (1)
Also from the question,
Three tickets in Switzerland plus two tickets in Japan would cost $76.97. That is
2x + 3y = 76.97 ...... (2)
Multiply equation (1) by 2, so that we get
6x + 4y = 162.16 ...... (3)
and multiply equation (2) by 3, so that we get
6x + 9y = 230.91 ...... (4)
Now, Subtract equation (3) from equation (4), we get
5y = 68.75
y = 68.75/5
y = 13.75
Put the value of y into equation (1) to determine x
3x + 2y = 81.08
3x + 2(13.75) = 81.08
3x + 27.5 = 81.08
3x = 81.08 - 27.5
3x = 53.58
x = 53.58/3
x = 17.86
∴ x = 17.86 and y =13.75
Hence, the average cost of a movie ticket in Japan is $17.86 and the average cost of a movie ticket in Switzerland is $13.75.

Answer:
The pentagon shape = 8
The star shape = 6
The curl shape = 3
The wave pattern shape = 5
Step-by-step explanation:
Let the pentagon shape = w, the star shape = x, the curl shape = y, and the wave pattern shape = z
Horizontally, we have;
w + 2·x + y = 23.....(1)
2·y + 2·z = 16...........(2)
2·z + w + x = 24.. ..(3)
3·y + x = 15..............(4)
Vertically, we have;
2·x + z + y = 20.......(5)
2·y + w+ z = 19........(6)
From the above equations, we have;
From equation (4), we have x = 15 - 3·y
From equation (2), we have z = 8 - y
From equation (1), we have w = 23 - (2·(15 - 3·y) + y)
∴ w = 23 - 30 + 6·y - y = 5·y - 7
w = 5·y - 7
Substituting the above values for x, and z i equation (5) gives;
2·x + z + y = 2·(15 - 3·y) + 8 - y + y = 20
30 - 6·y + 8 - y + y = 20
6·y = 30 + 8 - 20 = 18
y = 18/6 = 3
y = 3
w = 5·y - 7 = 5×3 - 7 = 8
w = 8
z = 8 - y = 8 - 3 = 5
z = 5
x = 15 - 3·y = 15 - 3×3 = 15 - 9 = 6
x = 6
Therefore, we have;
w = The pentagon shape =8
x = The star shape =6
y = The curl shape = 3, and
z = The wave pattern shape =5
The number of each of the four given shapes filled in the rows and columns are;
8 inscribed pentagon shape
6 star shapes
3 spiral shapes
5 Waves inside rectangle shape
From the diagram, we see four shapes and so let us identify them with letters;
Inscribed pentagon shape = a
Star shape = b
Spiral shape = c
Waves inside rectangle shape = d
For the first row, we see 2 stars, one inscribed pentagon and one spiral shape. Thus;
a + 2b + c = 23 .....(eq 1)
For the second row, we see 2 spiral shapes and 2 Waves inside rectangle shape. Thus;
2c + 2d = 16 ......( eq 2)
For the third row, we see 1 star, one inscribed pentagon and 2 Waves inside rectangle shape. Thus;
a + b + 2d = 24 ....(eq 3)
For the fourth row, we see 3 spiral shapes and one star shape. Thus;
b + 3c = 15 ....(eq 4)
Looking at the columns, we see that;
First column;
2c + a + d = 19 ....(eq 5)
Second column, we have;
2b + c + d = 20 .....(eq 6)
From eq 4; b = 15 - 3c
From eq 2, we have; d = 8 - c
Putting them in eq 1 gives;
a + 2(15 - 3c) + c = 23
a + 30 - 6c + c = 23
a = 5c - 7
Putting d = 8 - c and a = 5c - 7 into eq 5 gives;
2c + 5c - 7 + 8 - c = 19
6c + 1 = 19
6c = 18
c = 3
Put 3 for c in a = 5c - 7
a = 5(3) - 7
a = 8
Put 3 for c in b = 15 - 3c
b = 15 - 3(3)
b = 6
Put 3 for c in d = 8 - c
d = 8 - 3
d = 5
Thus, we have;
8 inscribed pentagon shape
6 star shapes
3 spiral shapes
5 Waves inside rectangle shape
