1.A.
The base lengths of the trapezoid are 35cm and 19cm. The height is 15cm.
1.B.
The formula for the area of a trapezoid is
A=(b1+b2)/2*h
plug in the data we know
A=(35+19)/2*15
A=54/2*15
A=27*15
A=405cm²
since there are two trapezoids, we double that number 405*2=810cm²
Answer=810cm²
1.C.
To solve for this, we need to find the perimeter of the trapezoid
P=35+19+17+17=88cm
Answer=No. The edges of the trapezoid are longer than 80cm.
2.A.
3units. Since their x values are the same, you just subtract the y values to calculate distance 5-2=3
Answer=3
2.B
A right triangle. Since one coordinate is directly above, and the other is directly to the right of the bench
3.A
The two triangles would be...
A=1/2b*h=1/2*30*72=15*72=1080ft² each
and the center rectangle would be
A=l*w=20*72=1440ft²
Add them all together and you get
Total area=3600ft²
Adding 25% is multiplying by 1.25:
$12 × (1 + 25/100) = 12(1.25) = $15
Answer: $15
Answer:
40%
Step-by-step explanation:
The probability he misses at least one of the targets is 1 minus the probability that he hits all of the targets.
P = 1 − 0.95¹⁰
P = 1 − 0.599
P = 0.401
Rounded, there is a 40% chance he misses at least one target.
Answer:
8:64
Step-by-step explanation:
I'm not sure tho. hope you get it right!!!
16/40 x 100 =40
so the answer is 40
