Can I see the rest of the problem of number 18 please
Answer:
- premium: 165 gallons
- water: 120 gallons
Step-by-step explanation:
Let 'a' represent the amount of 95% antifreeze in the mix. Then the amount of water is (285 -a). The mix has this amount of antifreeze in it:
0.95a +0(285 -a) = 0.55(285)
a = 0.55/0.95(285) = 165 . . . gallons of 95%
285 -a = 285 -165 = 120 . . . . gallons of water
There are 120 gallons of water and 165 gallons of premium antifreeze in the mixture.
Hello there!
1. The theoretical possibility of spinning every number out of the 200 spins is approximately to the nearest whole number: 16 times. We found that by dividing 200 by 12 to see how many of each number could fit in 200. 200 divided by 12 equals 16.666 but we can't spin a number 16.6 times so we have to round it to the nearest whole number that stays in the range of 200.
2.
i. The experimental probability of spinning a 1 is 20/200 or 1/10.
ii. The experimental probability of spinning an 8 is 30/200 or 3/20.
iii. The experimental probability of spinning an 11 is 2/200 or 1/100.
3. The numbers on the spinner that has a greater experimental probability than the theoretical probability is: 1,2,5,6,8, and 9.
Experimental probabilities:
2: 18/200 or 9/100
5: 17/200
6: 26/200 or 13/100
9: 18/200 or 9/100
Given:
A figure of a right triangle with perpendicular 500 m and hypotenuse x.
To find:
The value of x.
Solution:
If a transversal line intersect two parallel lines, then alternate interior angles are congruent.
Using the above definition the measure of angle opposite to the perpendicular is 40 degrees.
In a right angle triangle,
In the given triangle,
Round the value to the nearest tenth.
Therefore, the value of x is 777.9 m.
