And object is traveling at a steady speed of 8 2/3 mph how long will it take to object to travel 5 1/5 miles

1 answer:

8 0

$\bf \begin{array}{ccll}
miles&hours\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
8\frac{2}{3}&1\\\\
5\frac{1}{5}&h
\end{array}\implies \cfrac{8\frac{2}{3}}{5\frac{1}{5}}=\cfrac{1}{h}\implies \cfrac{\quad \frac{26}{3}\quad }{\frac{26}{5}}=\cfrac{1}{h}\implies \cfrac{26}{3}\cdot \cfrac{5}{26}=\cfrac{1}{h}
\\\\\\
\cfrac{5}{3}=\cfrac{1}{h}\implies 5h=3\implies h=\cfrac{3}{5}$

which is just 36 minutes.

The area of a sector of a circle is given by the equation , 3.142S/360 where r is the radius of the circle and S is the angle me

Diano4ka-milaya [45]

Given that the area of the sector is given by:
A=3.142r² S/360
where:
r is the radius
S is the angle measure of the sector
If Mia solved the equation for S, the equations that she wrote would be found as follows;

From A=3.142r² S/360
making S the subject by first dividing both sides by 3.142r^2 we shall have:
A/3.142r²=S/360
next we multiply both sides by 360
360×A/3.142r²=S/360×360
this will give us
(360A)/(3.142r²)=S
therefore the equation that Mia will get is:
S=(360A)/(3.142r²)

Eve measured a county park and made a scale drawing. The picnic area, which is 68 yards wide in real life, is 34 inches wide in

mote1985 [20]

Answer:

Eve used scale as 2 yards is equal to 1 inch.

Step-by-step explanation:

Given:

Actual Picnic area = 68 yards.

Drawing Picnic area = 34 inches.

We need to find the scale used by Eve.

Solution:

Now we can say that;

scale used by Eve can be calculated by dividing Actual Picnic area from drawing picnic area.

framing in equation form we get;

scale used by Eve = $\frac{68}{34} = 2\ yd/in$

Hence Eve used scale as 2 yards is equal to 1 inch.

Two airplanes leave the airport. Plane A departs at a 44° angle from the runway, and plane B departs at a 40° angle from the run

lawyer [7]

Answer: Answer:

Plane B was farthest away from the airport

Step-by-step explanation:

"This question requires you to visualize the run way as the horizontal distance to be covered, the height from the ground as the height gained by the plane after take of and the distance from the airport as the displacement due to the angle of take off.

In plane A

The take-off angle is 44° and the height gained is 22 ft.

Apply the relationship for sine of an angle;

Sine Ф°= opposite side length÷hypotenuse side length

The opposite side length is the height gained by plane which is 22 ft

The angle is 44° and the distance the plane will be away from the airport after take-off will be represented by the value of hypotenuse

Applying the formula

sin Ф=O/H where O=length of the side opposite to angle 44° and H is the hypotenuse

In plane B

Angle of take-off =40°, height of plane=22miles finding the hypotenuse

Solution

After take-off and reaching a height of 22 ft from the ground, plane A will be 31.67 miles from the airport

After take-off and reaching a height of 22 ft from the ground, plane B will be 34.23 miles away from the airport."
