Si por el consumo de 80m de agua se pagan $57 ¿cuánto se pagaron por 50m de agua?

Answers

I hope you can understand me, but $57 for 80m of water. So you divide 57 by 80. That equals 0.7125. Now you have the unit price of one m of water. Since you’re looking for the price of 50m of water, you multiply 0.7125 by 50, which equals 35.625. Since you’re talking about dollars, you need to round to the nearest hundredth. Therefore, the price for 50m of water is $35.63. I hope this helps.

Which statement is true of the numbers 39/7 and-0.3287 A Only 39/7 is rational. B Only -0.328 is rational. C Both numbers are rational. D Both numbers are not rational.​

Answers

Both numbers are rational numbers, so the correct answer is (C).

What are rational numbers?An irrational number cannot be expressed using fractions, whereas a rational number can be expressed as the ratio of two integers with the denominator not equal to zero. Irrational numbers are non-terminating and non-recurring, whereas rational numbers have terminating decimals. It is now possible for 12 rational numbers between -1 and 2 to be: 0, 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, -0.1, -0.2, and -0.3. It's important to remember that there are other solutions besides the 12 rational numbers listed above.

So,

39/7 is already a rational number as it is already in a fraction with a denominator not equal to zero.

And -0.3287 can also be expressed in fractions where the denominator will not be equal to 0. (Refer to the image below for work)So, we can say that both numbers are ratio numbers.

Therefore, both numbers are rational numbers, so the correct answer is (C).

Why are  rational number?

The ratio or fraction among two numbers, p/q, where both p and q are the numerator and denominator, respectively, can be expressed as a rational number. For example, 3/7 and any integer represent rational numbers..

Why are numbers irrational and rational?

Rational numbers can really be expressed as ratios (such P/Q and Q0), while irrational numbers can indeed be expressed as a fraction. Both of these numbers, nevertheless, are real and can be displayed on a number line.

According to the given data:

39/7 and-0.3287

The decimal number as a fraction:

0.3287  = 0.3287/1

this can be written as:

[tex]\frac{0.3287}{1}[/tex] x [tex]\frac{1000}{1000}[/tex]  = [tex]\frac{3287}{1000}[/tex]

Find the inverse of each function.
y=log₂4 x

Answers

The inverse function of the function y = log₂ 4x is f ⁻¹(x) = 2ˣ/4.

Given the function is :

y = log₂4x

we are asked to find the inverse of the function.

steps to find inverse function are:

Change f(x) to y to get y = ax + b for the provided function f(x) = ax + b.To get x = ay + b from the equation y = ax + b, replace x with y and y with x.Here, find y and solve for x = ay + b. Then we get y = (x - b/a).Finally, we can substitute y = f-1(x) with f-1(x) = (x - b)/a.

now interchange the positions of x and y in the function.

x = log₂4y

the next step is to isolate the dependent variables.

f ⁻¹(x) = 2ˣ/4

hence, we get the inverse of the given function as f ⁻¹(x) = 2ˣ/4

Answer: at least 87.74

Explanation: We can model this with an equation where your balance must be at least 250. "At least" means greater than or equal to, so the account balance must be greater than or equal to 250. The balance is your starting amount minus any purchases and plus any deposits, so:

The measures of the angles are

TLN = 51 degrees, NLM = 129 degrees and MZQ =  129 degreesJZQ = TLN = 99 degreesLMO= ZMR = 34 degrees and  LMR = y = 166 degrees

How to determine the measures of the angles?

1. Angle TLN, MZQ and NLM

The angles TLN and NLM are supplementary angles

So, we have

TLN + NLM = 180

This gives

3x - 18 + y = 180

Also, we have

TLN + MZQ = 180

So, we have

3x - 18 + 5x + 14 = 180

Evaluate the like terms

8x -4 = 180

This gives

8x = 184

Divide

x = 23

Substitute x = 23 in 3x - 18 + y = 180

3 x 23 - 18 + y = 180

Evaluate

51 + y = 180

So, we have

y = 129

The above computations imply that:

TLN = 3 x 23- 18 = 51 degrees

NLM = y = 129 degrees

MZQ = 5 x 23 + 14 = 129 degrees

2. Angle JZQ and TLN

The above means that

JZQ = TLN

So, we have

9x + 9 = 8x + 19

Evaluate

x = 10

So, we have

JZQ = TLN = 9 * 10 + 9

JZQ = TLN = 99 degrees

3. Angle ZMR, LMO and LMR

The angles ZMR and LMO are congruent angles

So, we have

ZMR = LMO

This gives

x + 14 = 2x - 6

Evaluate

x = 20

Also, we have

LMR + LMO = 180

So, we have

y + 2x - 6 = 180

y + 2 x 10 - 6 = 180

y + 14 = 180

So, we have

y = 166

The above computations imply that:

LMO= ZMR = 20 + 14 = 34 degrees

LMR = y = 166 degrees

A point on the edge of a symmetrical canyon is 4500 feet above a river that cuts through the canyon floor. The angle of depression from each side of the canyon to the canyon floor is 60o.

a) Find the length of the canyon wall (from the edge to the river).
feet

b) Find the distance across the canyon.
feet

c) Is it more or less than a mile across the canyon? (5280 feet = 1 mile) more or less

Answers

The length and distance across the canyon is 5196.15 feet and it is more than 1 mile.

a) To find the length of canyon, we will sine function. As per the sine theta = length of opposite side ÷ hypotenuse. Keep the values in formula to find the hypotenuse, which is the length of the canyon wall.

sin 60 = 4500 ÷ hypotenuse

Hypotenuse = 4500 ÷ (✓3/2)

Hypotenuse = 4500 × 2 ÷ ✓3

Hypotenuse = 9000 ÷ ✓3

Hypotenuse = 5196.15 feet

The length of the canyon wall is 5196.15 feet.

b) To find the distance across the canyon, we will use cosine function. As per the cos theta = base ÷ hypotenuse. Keep the values in formula to find the base, which is half the length of the distance across the canyon.

cos 60 = base ÷ 5196.15

cos 60 × 5196.15 = base

Base = (1/2) × 5196.15

Base = 2958.075 feet

Total distance across the canyon = 2958.075 + 2958.075

Tota distance across the canyon = 5196.15 feet

c) Using the relation, 5280 feet = 1 mile

5196.15 feet = 5196.15 ÷ 5280 mile

5196.15 feet = 1.12 miles

So, distance across the canyon is more than 1 mile.

f (x) = x + 1 and g (x) = x² - 3 x - 4

We need to find the composite function:

Substituting the values, we get that:
