Answer:

Option b) 17.1 mph

Step-by-step explanation:

Given that a bicycle’s speedometer measures speed to the nearest 0.1 miles per hour.

There are 4 options given and we have to select the option which is nearest to 0.1 miles per hour.

Option a) is incorrect because 17mph is rounded off to the nearest integer.

Option C) is incorrect because 17.15 mph is rounded off upto 0.01

Option d) is incorrect because 20mph is rounded off to the nearest integer.

Optionb) 17.1 mph here miles rounded off to 0.1 miles per hour. So this is correct option

What is the perimeter of the parallelogram???
enot [183]
Answer: 22

explanation: the easiest way is to separate one of the diagonals into a triangle and use the pythagorean theorem.
a^2 + b^2 = c^2
4^2 + 3^3 = c^2
16 + 9 = c^2
25 = c^2
5 = c
you now know that both of the diagonals have a length of 5.
by counting the units on the two straight, you know that their length is 6.
6 + 6 + 5 + 5 = 22

The selling price of a​ refrigerator, is ​$ 796.40 . If the markup is 10 % of the​ dealer's cost, what is the​ dealer's cost of
8_murik_8 [283]

The final price (what it is selling for) is $796.40

The markup is 10% of the original price (the dealer's cost) , meaning that it is 10% more.

We need to find the original price.

We write this as an equation

The original price *110% = final price

This is because the original price is itself (100%) added with 10%

Plug in the known final price

Original Price * 110% = 796.40

Convert 110% to a decimal because the other numbers- such as the final price are also decimal numbers.

Convert 110% to a decimal by moving the decimal point up 2 spaces ( basically dividing it by 100)

110% = 1.1

So it is now

Original price *1.1 = 796.40

Divide both sides by 1.1 to isolate our unknown, the original price

Original price = $724

IrinaVladis [17]

Answer:

24°

Step-by-step explanation:

The diagram attached is a pictorial representation of the position of the Gun Boat and the Enemy ship. We want to determine the given angle.

Tan \theta= \frac{Opposite}{Adjacent}

Tan \theta= \frac{150}{330}

\theta= arctan (\frac{150}{330})

\theta= 24.4^{0}

The angle of elevation is 24° to the nearest degree.
