Answer: 9 inch
Step-by-step explanation:
Given
Distance between city A and city B is 540 miles
Scale on the map is 1 inch: 60 miles i.e. 1 inch on the map is equivalent to 60 miles in the real situation
suppose the distance between city A and B on the map is x
[tex]\therefore \dfrac{1}{60}=\dfrac{x}{540}\\\\\Rightarrow x=\dfrac{540}{60}=9\ in.[/tex]
Therefore, the distance between city A and B is 9 in.
32^1/25 x 2^x = 8^1/4. work out the exact value of x.
Answer:
The exact value of x is 2.Step-by-step explanation:
To find the exact value of x, we need to solve the given equation for x. The equation is:
32^1/25 x 2^x = 8^1/4
To solve this equation, we need to rewrite it in a form that allows us to isolate the variable x. We can start by using the properties of exponents to simplify the left-hand side of the equation. We can use the property that says that raising a number to a fractional power is the same as taking the square root of that number, raised to the power of the denominator of the fraction. So, we can write:
(32^1/25)^2 = (32^1/25)^25/25 = 32^1/25
This simplification allows us to rewrite the left-hand side of the equation as follows:
32^1/25 * 2^x = (32^1/25)^2 * 2^x
Next, we can use the property of exponents that says that the product of two numbers raised to the same power is equal to the product of the numbers, raised to that power. So, we can rewrite the left-hand side of the equation as follows:
(32 * 2)^1/25 * 2^x = (32^1/25)^2 * 2^x
Then, we can use the property of exponents that says that raising a product to a power is the same as raising each factor to that power. So, we can rewrite the left-hand side of the equation as follows:
(32^1/25) * 2^(1/25 + x) = (32^1/25)^2 * 2^x
Finally, we can use the property of exponents that says that the exponent of a power is equal to the product of the exponents of the base and the power. So, we can rewrite the left-hand side of the equation as follows:
(32^1/25) * 2^(1/25 * 25 + 1 * x) = (32^1/25)^2 * 2^x
Since the right-hand side of the equation is already in a form that allows us to isolate the variable x, we can now use the property of exponents that says that raising a number to a power and then taking the square root of that number is the same as
Are all equilateral triangles similar and congruent?
Yes, All equilateral triangles are similar to each other.
No, All equilateral triangles are not congruent to each other.
How all equilateral triangles are similar?The fact that every angle in an equilateral triangle is equal to 60 degrees is one of its characteristics.
According to the AAA Triangle Similarity Postulate, two triangles are similar if all of their angles are identical to their corresponding angles in another triangle.
According to the AAA Postulate, all equilateral triangles are similar because their angles are all 60 degrees.
why all equilateral triangle are not congruent?The reason is that although an equilateral triangle's angles are all 60 degrees, their corresponding sides are not necessarily the same .

What is the vertex of the graph of f x )=[ x 5 ]- 6?
The vertex of the graph of f(x) = |x - 5| - 6 is (5, -6). It lies in the fourth quadrant.
Therefore the answer is (5, -6).
The graph f(x) = |x - 5| - 6 is symmetrical about the axis x = 5.
A vertex of a graph is a node of a graph. For a graph of the form f(x) = a|x - h| + k, the vertex is (h, k). So in this case where f(x) = |x - 5| - 6, a = 1, h = 5 and k = -6. Therefore the vertex of the given graph f(x) is

Use the Law of Cosines to find the values of x°and y°. Round to the nearest tenth.
The value of x° and y° are 26.8° and 86.2°.
What is rounding to tenth?
Look at the hundredth number to round the decimal number to the nearest tenth. If it's more than 5, add one to the tenth value. Remove all the numbers that are present after the tenth place and leave the tenth place value alone if it is less than 5.
The length of sides of the triangle are 8, 6, and 5.
Assume that AB = c = 6, BC = a = 5, and AC = b = 8
m∠A = x° and m∠B = y°.
Cosine law:
c² = a² + b² - 2ab cos C ....(i)
b² = a² + c² - 2ac cos B ....(ii)
a² = b² + c² - 2bc cos A ....(iii)
Putting a = 5, b = 8, c = 6, and A = x° in law (iii)
5² = 8² + 6² - 2×8×6 cos x
25 = 64 + 36 - 84 cos x
84 cos x = 75
cos x = 75/84
x = 26.76°
x = 26.8° (nearest tenth)
Putting a = 5, b = 8, c = 6, and B = y° in law (ii)
8² = 5² + 6² - 2×5×6 cos y

overtime pay rate is 150% of the normal rate. Matias makes 5% commission
on all jewelry he sells. Who earns more money in a week if Tori works
60 hours and Matias sells $21,000 worth of jewelry? Explain.
Divide the base for that period by the appropriate commission rate to determine your commission for that period. Mark earns more money.Since $1680 > $1080, Mark earns more.
Who makes the most money each week?This is a pretty straightforward computation based on percentages. Simply take the selling price, multiply it by the commission rate, then divide the result by 100.
Mark: $24/h; 150% OT
Calculate Mark's overtime (OT) pay
Convert OT rate to decimals --> 150% = 1.5
Mark's OT wage is 1.5*$24 = $36
Mark worked for 20h OT. (60h-40h = 20h)
(Regular pay X regular hours worked) + (OT wage X OT hours worked)
= ($24 X 40h) + ($36 X 20h)
= $1680
Joe: 5% commission
Convert 5% to decimals --> 0.05
(Jewelry sold) X (commission rate)
= $21000 X 0.05
