Answer:
195
Step-by-step explanation:
1) formula of the required area is:
A=0.5*d₁*d₂;
2) according to the formula above the required area is:
A=0.5*(7.5*2)*(13*2)=0.5*15*26=195 (yd²).
well if
120-74=46
then 46 is the correct answer.
74+46= 120
46 more students can sign up for the field trip.
Answer:
You should test out with different objects in different places. But, I would be careful not to use anything that could break!
Answer:
The answer is 149ft
Step-by-step explanation:
20 x 7 = 140 + 9 = 3x3
Not sure if this is correct
The correct answer is G) 4.5 mi.
Let b be the length of the blue route and g be the length of the green route:
6g+5b=52
12g+13b=119
We will use elimination to solve this. We will make the coefficients of g equal by multiplying the first equation by 2:
2(6g+5b=52) → 12g+10b=104
Now we will subtract the second equation from this:
12g+10b=104
-(12g+13b=119)
-3b=-15
Divide both sides by -3, and we have
b = 5
Substitute this into the first equation:
6g+5(5)=52
6g+25=52
Subtract 25 from both sides:
6g=27
Divide both sides by 6:
g = 27/6 = 4.5
