A plane traveling at a constant speed flew over

Mathematics
1 answer:
kumpel [21]3 years ago

Answer:

1. Its constant speed is 550 miles per hour.

2. Time taken to fly from Albuquerque to Phoenix is \frac{3}{5} hours (36 minutes).

Step-by-step explanation:

Speed = \frac{distance}{time}

a. Its speed from Pittsburgh to Saint Louis can be calculated by;

speed = \frac{550}{1}

           = 550 miles/hour

b. Its speed from Saint Louis to Albuquerque can be determined by;

42 minutes = \frac{42}{60} hours

                   = \frac{7}{10} hours

so that time taken = 1\frac{7}{10} hours

speed = \frac{935}{1\frac{7}{10} }

          = \frac{9350}{17}

          = 550 miles/hour

c. From Albuquerque to Phoenix, let the time be represented by t. We have;

speed = \frac{330}{t}

since the speed is constant, then'

550 = \frac{330}{t}

⇒ t = \frac{330}{550}

      = \frac{3}{5}

Thus, time taken to fly from Albuquerque to Phoenix is \frac{3}{5} hours (36 minutes).

A candy bar box is in the shape of a triangular prism the volume of the box is 2400 cubic centimeters part A: what is the height
Whitepunk [10]
The volume of a triangular prism is the "area of a triangle" times the "thickness."
The area of a triangle is (base times height) over 2.
V = ((b*h)/2)*T
Given V = 2400 cu. cm, b = 16 cm, T = 20 cm, and h is unknown,
h = (2V)/(bL) = (2*2400)/(16*20) = 15 cm

Note that the given 17 cm in the picture is useless.

Kirk's family drove 36 miles in 50 minutes, which was 48% of the distance to his grandmother's house. What was the total distanc
Makovka662 [10]

Answer:

Option D is correct.

75 miles is the total distance in miles to Kirk's grandmother's house

Step-by-step explanation:

Let x represents the total distance in miles to Kirk's grandmother's house.

As per the statement:

Kirk's family drove 36 miles in 50 minutes, which was 48% of the distance to his grandmother's house

⇒ Distance Kirk's family drove = 36 miles.

then;

36 = 48% of x

36 = \frac{48}{100}x

Multiply both sides by 100 we get;

3600 = 48x

Divide both sides by 48 we have;

75 miles = x

Therefore, the total distance in miles to Kirk's grandmother's house is 75 miles
