Surface area of this triangular prism is

Area of 2 congruent triangles + Area of rectangle(6*2) + Area of rectangle(2*4) + + Area of rectangle (2*3)

Area of triangle = 1/2*6*2 =6 in²

Surface area of this triangular prism = 2*6 +6*2 +2*4 +2*3= 12+12+8+6= 38 in²
Answer is 38 in².

A hole the size of a photograph is cut from a red piece of paper to use in a picture frame.

mario62 [17]

Answer:

D. 47 square units

Step-by-step explanation:

The area of the piece of red paper after the hole for the photograph has been cut is the difference between the area of large square and are of small square.

Area of large square:

The length of the side of large square is

$EF=|-4-4|=8\ units$

Area of large square $=8^2=64\ un^2.$

Area of small square:

The length of the side of large square is

$AB=\sqrt{(-3-(-2))^2+(-2-2)^2}=\sqrt{(-1)^2+(-4)^2}=\sqrt{1+16}=\sqrt{17}\ units$

Area of small square $=\sqrt{17}^2=17\ un^2.$

Difference:

$64 \ un^2-17\ un^2=47\ un^2$

The space shuttle travels at 28,000 km per hour. Using that information, estimate how many hours it will take the shuttle to rea

spayn [35]

Subtract the distance of the Earth from the sun from the distance of Saturn from the sun to find the distance from Earth to Saturn:

1,424,000,000 - 149,600,000 = 1,274,400,000 km ( Saturn from Earth)

Divide the distance by the speed to find the time:

1,274,400,000 km / 28,000 km per hour = 45,514.2857 hours.

Round to 45,514 hours.

Chana and Josiah started skating at the same time in the same direction, but Josiah had a head start 10 meters past the starting

kodGreya [7K]

Josiah and Chana travel at constant and different speeds.

The point F indicates that after 25 seconds Josiah is 60 meters from the starting line but behind Chana

<h3>How can the what the the point F represent be known?</h3>

Josiah's head start = 10 meters from the start

Josiah's speed = 2 m/s

Chana's speed = 3 m/s

Expressing the distance traveled as an equation, we have;

D = d + s × t

Where;

D = The distance covered

d = The distance from the starting line the runner starts

s = The speed of the runner

t = The time spent running

For Josiah, we have;

D = 10 + 2•t (line a)

For Chana, we have;

D = 0 + 3•t = 3•t (line b)

The above equations are straight line equations.

The point F is on line a, which shows Josiah distance after 25 seconds which is 60 meters. The corresponding point on line b, Chana's distance after 25 minutes is 75 meters.

Therefore;

The point F indicates that after 25 seconds Josiah is 60 meters from the starting line but behind Chana
