Answer:
a) We can just add Distance from Tulsa to Dallas and distance from Dallas to Houston,
258 + 239 = 497
b) It's the same distance = 497
c) We can tell its the same distance, because we are travelling in the same road, which would mean it would be no different when going to or coming back from Houston.
Answer:
wilma is 22.5 mph
fred is 25.5 mph
Step-by-step explanation:
Time:40 minutes, or 2/3 hours
Speed:
Fred:x+3
Wilma: x
Distance:32 miles
2/3(x+x+3)=32
2/3(2x+3)=32
1 1/3x+2=32
4/3x=30
x=22.5
wilma is 22.5 mph
fred is 22.5+3= 25.5 mph
Answer:
this mean in case of multiplying exponents with same base you should add the exponent and keep base same.
example:
Answer:
860cm²
Step-by-step explanation:
1. area of the side triangle:
(15×8)×2= 120×2= 240cm²
there's two side triangles with the same length and width, so just multiply by two.
2. area of the square on top:
20×8= 160cm²
3. area of the rectangle behind:
20×8= 160cm²
4. area of the square below:
20×15= 300cm²
5. the total of all areas (surface area):
240+160+160+300= 860cm²
Answer:
Step-by-step explanation:
Well depends the shape
volume of a rectangular solid : V = length * width * height, or V = lwh.
volume of a triangular pyramid: V=13Ah
Volume of a cone: V=πr^2 h
/3
etc..
