Answer:

9.9 is your answer

Step-by-step explanation:

by using Pythagoras law

p²+b²=h²

7²+7²=x²

x=√{2×49)=7√2or 9.9 is your answer

Answer:

x = 9.9

Step-by-step explanation:

This is a isosceles triangle, with sides measurements (1 , 1 , √2), and the angles being (45° - 45° - 90°). Note that the side measurements of 1 is opposite of that of a 45°, while the measurement of √2 is opposite of that of 90°.

In this case, multiply. The side measurement of 1 has 7.

1 x 7 = 7

In the same, you must multiply 7 with √2

x = 7 * √2 = 7√2.

√2 = ~1.414

7 x 1.414 = 9.898

Round to the nearest tenth:

9.898 rounded to the nearest tenth = 9.9

x = 9.9

OLEGan [10]

Answer:

20,4

Step-by-step explanation:

Suppose that x, y are the the length and width

Area=x*y=80

Parameter=2(x+y)=48....x+y=24

Xy=80...x(24-x)=80...x=20,y=4

Assuming that Hamid’s revenue is found by multiplying the book price by the number of copies sold, create an equation (in standa
Vadim26 [7]

An equation of Hamid’s revenue by multiplying the book price by the number of copies sold is  x = ny.

<h3>What is an equation?</h3>

The process of equating one thing with another.

Let Hamid’s revenue is $x and the price of book is $y.

If he sold n number of copies.

Then, the general equation will be x = n * y.

Therefore, an equation of Hamid's revenue will be x = ny.

The formula for the cost of buying a car is:
Mice21 [21]

Answer:

a) The cost of buying this car is of £6200.

b) The monthly payment is of £450.

Step-by-step explanation:

The cost of buying a car is given by:

cost = 12 X monthly payment + deposit

a) Find the cost of a car when the monthly payment is £350 and the deposit is £2000.

So

cost = 12*350 + 2000 = 4200 + 2000 = 6200

The cost of buying this car is of £6200.

b) The cost of another car is £8000. Find the monthly payment when the deposit is £2600.

Again, the formula is applied. So

cost = 12 X monthly payment + deposit

8000 = 12x + 2600

12x = 5400

x = 5400/12

x = 450

The monthly payment is of £450.

A pole 11 feet tall is used to support a guy wire for a tower, which runs from the tower to a metal stake in the ground. After p
Juliette [100K]

The given question is on trigonometry which requires the application of required <em>function</em> so as to determine the <em>value known</em>. So that the <u>length</u> of the guy wire is 67.0 feet.

<em>Trigonometry </em>is an aspect of mathematics that requires the application of some <u>functions</u> to determine the <em>value</em> of an unknown quantity.

Let the <u>length</u> of the guy wire be represented by l, and the angle that the guy wire makes with the <u>stake</u> be θ. So that applying the appropriate trigonometric function to determine the <em>value</em> of θ, we have:

Tan θ = \frac{opposite}{adjacent}

          = \frac{11}{4}

Tan θ = 2.75

θ = Tan^{-1} 2.75

  = 70.0169

θ = 70^{o}

Considering triangle formed by the <u>tower</u> and the <u>stake</u> to determine the value of l, we have;

Cos θ = \frac{adjacent}{hypotenuse}

Cos 70^{o}  = \frac{23}{l}

l = \frac{23}{Cos 70^{o} }

 = \frac{23}{0.3420}

l = 67.2515

l = 67 feet

The <u>length</u> of the guy wire is 67 feet.
