Answer:

Step-by-step explanation:

square root of 73 is about 8.5

square root of 10 is about 3. multiply by 3, you get 9.

square root of 7 is about 2.6. multiply by 5, you get 13.

when determining if you can make a triangle, if all variants of two sides can add up to be greater than the third side, you can make the triangle. so 8.5+9 > 13; 13+9 > 8.5; 13+8.5 > 9. this means it can make a triangle and all you have to do is order the sides.

8.5 is smallest which corresponds to angle c because it's opposite. 9 goes to angle a, then finally 13 goes to angle b. thus, angles c, a, b is the order.

side note: the smallest side length will always correspond with the smallest angle.

hope this helps :)

5 ft is ____ % of 37 1 2 ft; 37 1 2 ft is ____ % of 5 ft

hichkok12 [17]

Answer:

The answer is:

5 ft is 13.33% of 37 1/2 ft; 37 1/2 ft is 750% of 5 ft.

Step-by-step explanation:

Given:

5 ft is ____ % of 37 1 2 ft.

Now, to find the __ :

Let __ be $x.$

So, 5 ft is $x\%$ of 37 1/2

$5=x\% of 37\frac{1}{2}$

⇒ $5=\frac{x}{100} \times \frac{75}{2}$

⇒ $5=\frac{75x}{200}$

Multiplying both sides by 200 we get:

⇒ $1000=75x$

Dividing both sides by 75 we get:

⇒ $13.33=x$

⇒ $x=13.33\%.$

Now, 37 1/2 ft is $x$ % of 5 ft.

$\frac{75}{2} =x\%\ of\ 5$

$\frac{75}{2}=\frac{x}{100}\times 5$

$\frac{75}{2} =\frac{5x}{100}$

Multiplying both sides by 100 we get:

$\frac{7500}{2} =5x$

Dividing both sides by 5 we get:

$750=x$

$x=750\%$

Therefore, the answer is 5 ft is 13.33% of 37 1/2 ft; 37 1/2 ft is 750% of 5 ft.

you are going to run at a constant speed of 6.5 miles per hour for 30 minutes. you calculate the distance you will run. what mis

Rudiy27

The distance you run should be 6.5 * 30 / 60 which evaluates to 3.25 miles.

Pls pls help I’m really confused could someone explain to me pls

Answer: 11.6

--------------------------------------

Explanation:

See the attached image for a visual reference

The distance from point D to E is 21 units. Point C is the midpoint, so CD is 10.5 units long (21/2 = 10.5)

We have a right triangle ACD. The legs are
AC = 5
CD = 10.5
The hypotenuse is
AD = x
Because AD is another radius of the same circle

Use the pythagorean theorem to find x
a^2 + b^2 = c^2
5^2 + 10.5^2 = x^2
25 + 110.25 = x^2
135.25 = x^2
x^2 = 135.25
x = sqrt(135.25)
x = 11.629703349613
which rounds to 11.6 when rounding to the nearest tenth (one decimal place)
