Which equation models the cost for having Fernando clean a pool for x hours and how much will a 3-hour cleaning cost?

A. y=25x+15;90

Explanation:

Answers

Answer 1

Answer:

15x+25 ; 70

Step-by-step explanation:

Given that,

Fernando cleans pools for the summer for $25 an hour plus a supply fee of $15.

Here, $25 is constant and $15 increases as the number of hour increase. For x hours, the cost for Fernando to clean a pool is given by :

y = 15x+25

For 3 hours,

y = 15(3)+25

= 45 + 25

= 70

So, the required option is (c) " 15x+25 ; 70 ".

half the price as Ron. If they paid a total of $45 for the 2 pairs, how much did
each spend on their jeans?
PLEASE HELP 20 POINTS!!

Answers

Answer:

Ron paid $ 30 for his pair of jeans, while Tim paid $ 15 for the same model of jeans.

Step-by-step explanation:

Given that Ron paid X dollars for a pair of jeans, and Tim bought the same pair of jeans for half the price as Ron, if they paid a total of $ 45 for the 2 pairs, to determine how much did each spend on their jeans you must perform the following calculation:

X + 1 / 2X = 45

1X + 0.5X = 45

1.5X = 45

X = 45 / 1.5

X = 30

So Ron paid $ 30 for his pair of jeans, while Tim paid $ 15 for the same model of jeans.

evaluate the following expression log^6 8. round your answer to two decimal places
A.0.90
B.1.16
C.2.08
D.0.86

Answers

Answer:

B. 1.16

Step-by-step explanation:

Correct!

The following expression [tex]log^6 8[/tex] evaluates to 0.86. So, The correct  answer is 0.86.

We can evaluate the expression log^6 8 as follows:

[tex]log^6 8 = log 8 / log 6 = 0.90309...[/tex] which rounds to 0.86 to two decimal places.

Therefore, the correct answer is D.

Logs:

The exponential function's inverse is known as the logarithm, or log. In other terms, a number's logarithm is the power that a different number, b, must be raised to in order to equal that number.

The expression log x = b represents a logarithm and is symbolized by the symbol "log". This implies that b is equivalent to x when raised to the power of log b.

For instance, since 2 raised to the power of 3 is 8, the logarithm of 8 to the base 2 is 3.

Calculus, statistics, computer science, and other branches of mathematics all make use of logarithms. Numerous more practical uses include determining pH levels and decibel levels.

what is the approximate diameter of a sphere with a volume 34 cm the third power?​

Answers

Answer:

Diameter = 4cm________________

Step-by-step explanation:

volume = 34cm³

volume = 4/3×π×radius³

34cm³ = 4/3 × 3.14 × radius³

34cm³ = 12.56/3 × radius³

radius³ = 34×3/12.56

radius³ = 8

radius = ³√8

radius = 2cm

diameter = 2×radius

= 2×2

= 4cm

In ΔUVW, the measure of ∠W=90°, UV = 6.2 feet, and WU = 1.2 feet. Find the measure of ∠V to the nearest tenth of a degree.

Answers

Answer:

m<V = 11.2 degrees

Step-by-step explanation:

In ΔUVW, the measure of ∠W=90°, UV = 6.2 feet, and WU = 1.2 feet.

From the triangle;

UV = hypotenuse = 6.2feet

WU = opposite = 1.2feet

Required

m<V

Using the SOH CAH TOA identity

sin m<V = opp/hyp

sin m<V = WU/UV

sin m<V = 1.2/6.2

sin m<V = 0.1936

m<V = arcsin(0.1936)

m<V = 11.16

m<V = 11.2 degrees ((to the nearest tenth of a degree)

16.7 cm

Step-by-step explanation:

Area of a triangle = ½*base*height

Area of the shaded region = area of triangle = 100.2 cm³

base = w

height = 12 cm

Plug in the value into the equation:

½*w*12 = 100.2

6w = 100.2

w = 100.2/6

w = 16.7 cm
