Answer:
∠x = 72°
Step-by-step explanation:
since two sides are equal, their opposite angles are equal.
Then the upper angle is also equal to 54°.
All triangle angles add up to 180°.
∠x = 180 - 54 - 54 = 72°
Answer:
B
Step-by-step explanation:
x=√7
squaring
x²=7
It is given in the question that in the lemon squash 2 parts concentrate is added to 5 parts of water. Thus it makes the concentrate to water ratio as 2:5 or
. Now, if this ratio is maintained then the amount of water to be added to 90 ml concentrate in a glass can be calculated as:

Where x is the amount of water to be added, in ml (milliliters).
Cross multiplication of the above equation will give us:

Dividing both sides by 2 we will get:

Thus, if we put 90ml of concentrate in a glass, the water that should be added must be 225 ml.
There would be 6 waters and 5 snack mixes. Each water is 1.25, so 1.25x6 would be 7.50. And each snack is 2.50, so 2.50x5 would be 12.50. Adding those two or es together would be exactly $20 and adding all the items is 11. Hope this helps:)
Answer: 0.0898
Step-by-step explanation:
Probability = 
Given : Sample size : 528
Number pf customers say they are happy = 237
Probability of getting one happy customer= 
Probability of getting second happy customer=
[subtract 1 from both numbers]
Probability of getting third happy customer=
If 3 customers are elected without replacement
The probability they will all say they are happy with the service =

Hence, the required probability = 0.0898
