Answer:
2) d. 60°
3) a. AB
Step-by-step explanation:
<u>Question 2</u>
ΔABC and ΔCDA are <u>congruent</u> because:
- they are both <u>right triangles</u>
- they <u>share one side</u> (AC)
- their hypotenuse are <u>parallel</u> (marked by the arrows)
This means the corresponding side lengths and angles are equal.
Therefore,
∠CDA = ∠ABC
⇒ x = 60°
<u>Question 3</u>
The <u>hypotenuse</u> is the <u>longest side</u> of a <u>right triangle</u> - the side opposite the right angle (the right angle is shown as a small square).
Therefore, the hypotenuse of ΔABC is the line AB.
Answer:
60%
Step-by-step explanation:
let ,x% is birds of prey
total animals=110
birds of prey=66
then,
x%of 110=66
x/100×110=66
110x/100=66
1.1x=66
x=66/1.1
x=60%
I'm not sure if this is correct.
Answer: the number, converted to base 10 is 884
Step-by-step explanation:
The table gives symbols for a base 12 numerical system and it is called Caidoz numbers.
Looking at the table, the corresponding Caidozian number that we considering is 618 to base 12. Converting 618 to base 10, it becomes
8 × 12^0 = 8 × 1 = 8
1 × 12^1 = 1 × 12 = 12
6 × 12^2 = 6 × 144 = 864
Therefore, 618 to base 12 to 618 to base 10 would be
8 + 12 + 864 = 884
Answer:
a ≤ 3
Step-by-step explanation:
3a + 7 ≤ 16
3a ≤ 9
a ≤ 3
Subtract 7 from 16 to get 9, then divide 9 by 3 to get your answer.

Drinks, x, and popcorn, y.
38.75 = 5x+2y
37.25 = 3x + 4y
Let's solve this using the elimination method
subtract the 2nd row from the first
<span>7x=40.2<span>5
divide both sides by 7 to isolate x
</span></span><span>x=5.7<span>5
Substitute x into an equation
</span></span><span><span>10(5.75)+4y=77.5
multiply
</span></span>57.5+4y=77.<span>5
subtract 57.5 from both sides
</span>4y=77.5−57.<span>5
Simplify
</span>4y=2<span>0
divide both sides by 4 to isolate y
y = 5
To check you would plug x and y into the equations and see if it equals properly...
The price of drinks is $5.75, the price of popcorn is $5.
Hope this helps
