Answer:
∠XYZ = 74°
Step-by-step explanation:
∠XYZ = 
arcXZ
∠XYZ = 148°
∠XYZ = 74°
The sum of the sides of a triangle is equal to 180º.
The three angles will be: 3x,4x and 5x.
we can suggest the following equation:
3x+4x+5x=180
12x=180
x=180/12
x=15
The angles would be:
3x=3(15)=45
4x=4(15)=60
5x=5(15)=75
Answer: the highest angle would measure 75º.
Answer:
15.25
Step-by-step explanation:
The probability of getting a question right is 1/4 because there are 4 possible answers, and you're just guessing randomly.
You can expect to get 1/4 of the questions right.
<span>After deeply looking at the table it seems
z= .05
which means only 52% is less than Z
so, that is greater than z by 48%</span>
Answer:
B.
Step-by-step explanation:
So there are 16 grams initally. Then, the amount of water decreases by 3.5%.
So first we must find 3.5% of 16. 3.5% in decimal form is 0.035, since you divide 3.5 by 100. Then, when you multiply 0.035 by 16, you get 0.56. Since the solution decreased by that percentage, you must subtract 0.56 from 16, which is 15.44.
Then the amount of water decreases by 4.25%. That in decimal form is 0.0425. You multiply it by 15.44, and it comes out to 0.6562. You subtract that from 15.44, not 16, since some of the water has evaporated. So you get 14.7838.
