1 Explained:
12 * 3 = 36
36 - 24 = 12
Therefore if he had taken 3 times as many he would have had 36. And 36 is 24 more than 12.

In ΔVWX, x = 97 cm, v = 48 cm and ∠W=28°. Find the length of w, to the nearest centimeter.
Answers
The answer would be 59. This is for law of cosines (sas)
The requried length of side w is approximately 44 cm to the nearest centimeter.
What are trigonometric equations?These are the equation that contains trigonometric operators such as sin, cos.. etc, in algebraic operations.
To find the length of side w in ΔVWX, we can use the law of sines, which states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides and angles in the triangle. In other words:
w/sin(W) = x/sin(X)
where X is the angle opposite side x.
We are given x = 97 cm, v = 48 cm, and W = 28°. To find X, we can use the fact that the sum of the angles in a triangle is 180°:
X = 180° - W - V
X = 180° - 28° - 180°/2
X = 72°
Now we can plug in the values into the law of sines equation:
w/sin(28°) = 97/sin(72°)
Solving for w, we get:
w = sin(28°) * 97 / sin(72°) = 43.9 cm
Therefore, the length of side w is approximately 44 cm to the nearest centimeter.

Answers
Answer:
[tex](f\circ g)(8)=-3[/tex]
Step-by-step explanation:
Composite Function
Given f(x) and g(x) real functions, the composite function named [tex](f\circ g)(x)[/tex] is defined as:
[tex](f\circ g)(x)=f(g(x))[/tex]
For practical purposes, it can be found by substituting g into f.
The functions are defined as follows:
[tex]f(x)=x^2-4[/tex]
[tex]g(x)=7-x[/tex]
To find [tex](f\circ g)(8)[/tex], we evaluate g in x=8 and then apply the composition formula.
[tex]g(8)=7-8=-1[/tex]
[tex](f\circ g)(8)=f(g(8))[/tex]

XYZ’s print publication charges $15 for each of the first four lines of an ad, and $9 for each additional line. Express the cost of an x-line ad, c(x), as a piecewise function.
Answers
By using the given information we can infer the domains of the function, and we will see that the piecewise function is:
c(x) = $15*x if 0 ≤ x ≤ 4
c(x) = $60 + 9*(x - 4) if x > 4.
How to get the piecewise function?
We know that the print charges $15 for each of the first four lines on an add, and $9 for each additional line.
Then we will have one piece for x between 0 and 4, and another piece for x larger than 4. The function will be:
c(x) = $15*x if 0 ≤ x ≤ 4
c(x) = $60 + 9*(x - 4) if x > 4.
Where the y-intercept on the second part is equal to the cost for the first four lines of the add.

O Loss of $2,250
O Profit of $2,325
O Profit of $85,950
Answers
Answer:
profit of $2325
Step-by-step explanation:
so a loss of $4000 in the first month, with profit of $575 each month. let's say a year have 12 months, first month with loss, the other 11 months with profit. so, $575 x 11 months = $6325. $6325 is the amount for 11 months with $575 profit. take $6325 and minus with $4000 and you will get $2325, which is the profit for the first year.

the total angle of a triangle is 180°
since all of the sides of the triangle are even, then it means that all the angles are also equal
180 divided by 3 (because theres 3 angles) = 60
since one of the interior angle of the triangle is 60, the congruent angle of x also equals to 60° and also 60+60+60=180 (straight line)
i made a little diagram above for you, i hope it helps you and goodluck!! :)
The value of angle x is 60° in the triangle.
What is triangle?Triangle is defined as the polygons of the three-sided and three-sided variety. The fundamental equation for a triangle's area is A = 1/2 b h, where b and h are the product of the triangle's base and height. All triangle shapes, including scalene, isosceles, and equilateral triangles, can be calculated using this formula.
The exterior angle of a triangle is equal to the sum of the interior angles at the other two vertices, and angle x is one of the triangle's exterior angles.
Given that all three angles in a triangle are equal and all three sides of the triangle are even, the total angle of the triangle is 180°.
Since one of the interior angles of the triangle is 60°, the congruent angle of x is also 60°, therefore 60+60+60=180. (straight line).
So, the value of x is 60°
Thus, the value of angle x is 60° in the triangle.

(a) How cold was it in Oslo in °F?
(b) What temperature is it the same in °F and °C?
Answers
Answer:
(a)
Step-by-step explanation:
The relationship between temperatures measured in Fahrenheit, and in Celsius can be represented using equations.
The equations are: [tex]F = 1.8C + 32[/tex] and [tex]C = \frac{(F - 32)}{1.8}[/tex].The temperature in Oslo is [tex]60.8^oF[/tex].[tex]-40^oF[/tex] is equivalent to [tex]-40^oC[/tex]Given that:
[tex](F_1,C_1) = (32,0)[/tex]
[tex](F_2,C_2) = (212,100)[/tex]
First, calculate the slope (m)
[tex]m = \frac{C_2 - C_1}{F_2 - F_1}[/tex]
So we have:
[tex]m = \frac{100 - 0}{212 - 32}[/tex]
[tex]m = \frac{100}{180}[/tex]
[tex]m = \frac{5}{9}[/tex]
So, the equation is calculated using:
[tex]C= m(F - F_1) + C_1[/tex]
So, we have:
[tex]C = \frac 59(F - 32) + 0[/tex]
[tex]C = \frac 59(F - 32)[/tex]
Rewrite as:
[tex]C = \frac{(F - 32)}{9/5}[/tex]
[tex]C = \frac{(F - 32)}{1.8}[/tex]
To solve for F, we multiply both sides by 1.8
[tex]1.8C =F - 32[/tex]
Add 32 to both sides
[tex]F = 1.8C + 32[/tex]
(a) The temperature of Oslo in F
We have:
[tex]C = 16[/tex]
So, we make use of:
[tex]F = 1.8C + 32[/tex]
[tex]F = 1.8 \times 16 + 32[/tex]
[tex]F = 60.8[/tex]
The temperature in Oslo is [tex]60.8^oF[/tex]
(b) When F = C
We have:
[tex]F = 1.8C + 32[/tex]
Substitute F for C
[tex]F = 1.8F +32[/tex]
Collect like terms
[tex]F - 1.8F =32[/tex]
[tex]-0.8F =32[/tex]
Make F the subject
[tex]F = \frac{32}{-0.8}[/tex]
[tex]F = -40[/tex]
Hence,
[tex]-40^oF[/tex] is equivalent to [tex]-40^oC[/tex]

Answer:
We need to find the circumference, and in order to find the circumference we must know the formula for it.
Formula for circumference of a circle;
a = 2πr
Where π is the pi(3.14 or 22/7), and r is the radius which is half of the diameter.
Since we are given the diameter, we need to find the radius. So 1/2 of the diameter (26 x 1/2) = is 13
Now we just plug in the actual values in the formula:
a = 2πr
a = 2 x 3.14 x 13
a = 18.84 feet
But now, we need to find how many revolutions it would take to get to 500 feet.
So we divide 500 feet by 18.84 feet;
500/18.84 = 26.53, around 27 revolutions.
