The exponent of a number says how many times to use the number in a multiplication.
For Example, In 8² , the 2 is the number of times 8 has to be multiplied. In this case It has to multiplied by itself 2 times, 8x8 = 64 so 8² = 64.
Another example is 9³ since the number above is 3 we have to multiply 9 three times, 9x9x9 = 729 which means 9³ = 729.
Hope this helps
Answer:
△ AMC ≅ △ BMC ⇒ proved down
Step-by-step explanation:
Let us revise the cases of congruence
- SSS ⇒ 3 sides in the 1st Δ ≅ 3 sides in the 2nd Δ
- SAS ⇒ 2 sides and including angle in the 1st Δ ≅ 2 sides and including angle in the 2nd Δ
- ASA ⇒ 2 angles and the side whose joining them in the 1st Δ ≅ 2 angles and the side whose joining them in the 2nd Δ
- AAS ⇒ 2 angles and one side in the 1st Δ ≅ 2 angles and one side in the 2nd Δ
- HL ⇒ hypotenuse and leg of the 1st right Δ ≅ hypotenuse and leg of the 2nd right Δ
In Δ ABC
∵ CM ⊥ AB
∴ m∠AMC = m∠BMC = 90°
∴ ∠1 ≅ ∠2
In the two triangles AMC and BMC
∵ ∠1 ≅ ∠2 ⇒ proved
∵ ∠3 ≅ ∠4 ⇒ given
∵ CM is a common side in the two triangles
∴ CM ≅ CM ⇒ common side
→ Two angles and the side joining them in the 1st triangle ≅ two angles
and the side joining them in the 2nd triangle, then use the 3rd case
of congruency above
∴ Δ AMC ≅ Δ BMC ⇒ by using ASA postulate
The problem has to do with finding what percentage is one quantity over another.
We can solve as a rule of three, knowing that <span>$27,650 is the 100%
</span><span>$27,650 ----> 100%
1382.5 ------> x
x = (1382.5)(100)/</span><span>27650
x = 5
therefore, $</span>1382.5 is the 5% of $<span>27650</span>
Answer:
150
Step-by-step explanation:
Rolling a 2, 3, or 4 should happen approx 60% of the time
250 x 60%= 150
