Answer:
2362.5 km
Step-by-step explanation:
Speed= 450 km/hr
Time= 5 hr 15 min= 5 1/4 hr= 5.25 hr
distance= 450*5.25= 2362.5 km
I don't know the area of a parallelogram off the top of my head but you can use the area of the rectangle and the area of the triangle and add those. The area of the triangle is 1/2*base*height and use the pythagorean theorem to find the base. 3² + b² = 5²; 9 + b² = 25; b² = 16; b = 4. The area of the triangle is 1/2*4*3 or 6 in. Since there are two of them, the total area of the triangles are 12 in. The area of the rectangle is length*width or (12 - 4) * 3 which is 8 * 3 or 24in. Add these areas together to get 36in total
Answer:
3*8=24 --------- 35-24=11
Answer:
Perimeter: 30
Step-by-step explanation:
So we know that to get the area we multiply the height by the width and we already know the area and height.
Area: 50
Height: 5
So to find the width, we just divide:
50/5 = 10
So now we have everything we need to find the perimeter. The perimeter is all the sides added up. So, 5+10+5+10 = 15+15 = 30
Hope this helps
Answer:
x = 22/15
Step-by-step explanation:
2.5(6x-4)=10+(1.5+0.5)
Combine like terms
2.5(6x-4)=10+(2)
2.5(6x-4)=12
Divide each side by 2.5
6x-4 = 4.8
Add 4 to each side
6x = 8.8
Divide by 6
6x/6 = 8.8/6
x = 88/60
x = 22/15
