Answer: B) BC=4 in.
Step-by-step explanation:
Given: In △ABC , AB=4 inch ,AC=4 in. , and m∠A=60°
⇒ AB=AC= 4 inches
⇒ △ABC is an isosceles triangle.
⇒ m∠A=60°=m∠B [angles opposite to the equal sides of a triangle are equal]
Now by angle sum property,
m∠A+m∠B+m∠C=180°
⇒60°+60°+m∠C=180°
⇒ m∠C=180°-120°
⇒ m∠C=60°
⇒ △ABC is an equilateral triangle.
⇒ BC= 4 inches [sides of an equilateral triangles are equal]
⇒ B is the right answer.
Answer:
10p+12p+37
Step-by-step explanation:
Combine like terms:
12p-2p=10p
15t-3t=12t
24+13=37
10p+12t+37
hope this helps if not its ok ig
Circumference = 2πr
So the circumference of the track is C = 2π .2 or .4π
3 times around the track is .4π x 3 or 1.2π - this is the answer but most teachers will want you to use 3.14 for pi.
so 1.2 x 3.14 = 3.768 km
Do you notice that I waited until the end to use the actual value of pi (3.14) in my calculations.
Keeping things in pi units until the very end saves time.
Answer:B
Step-by-step explanation:
The value of x will be 7000 for the expression 12 % x = 840.
We are given a number x.
We are also given as 12 % of x is 840
writing it in the form of an expression, we get that:
12 % x = 840
12 / 100 × x = 840
12 x = 84,000
Dividing both sides by 12, we get that:
12 x / 12 = 84,000 / 12
x = 7000
Therefore, the value of x will be 7000.
