Answer:
Y= 2x+3
Step-by-step explanation:
The slope of two parallel lines are always the same.
1. To solve this problem, you must apply the formula for calculate the area of the trapezoid, which is:
A=(B+b)h/2
A is the area of the trapezoid (A=69.6 in²).
(B+b) is the sum of the bases of the trapezoid.
h is the height of the trapezoid (h=8.7 in).
2. When you clear the sum of the bases (B+b), you have:
A=(B+b)h/2
2A=<span>(B+b)h
</span><span> (B+b)=2A/h
</span> (B+b)=2(69.6 in²)/(8.7 in)
(B+b)=16 in
3. The problem says that <span>the sum of its legs is equal to the sum of its bases, therefore, the perimeter is:
</span>
Sum of the legs=Sum of the bases (B+b)=16 in
Perimeter=16 in+16 in
Perimeter=32 in
Answer:
Round up all costs
Least expensive: $6
Most expensive: $13
Half (half of 12 people is 6) ordered $10 calculators so 6x10=$60
Other half
(6+13)/2= $9.5 round up to $10 so 6x10=$60
$60 + 60=$120 best estimate $125

Answer:
5 units down
Step-by-step explanation:
To find the answer all you do is switch the percentage to a decimal and multiply by the number you were given. For example on 1a, 19% as a decimal is 0.19 and 0.19 * 360 is 68.4. All of 1 and 2 questions work this way. For number three, take the fraction and convert it to a decimal (so 1/2 will be 0.5, 1/3 will be 0.33, etc) and add that to the whole number. For example, 3a would be 33.33%. 3b would be 12.5%.
Hope this helps!
