Martha : 17% of 8 gallons
0.17(8) = 1.36 gallons
Brett : used 0.18
0.18(8) = 1.44
Mike : used 0.7
0.7(8) = 5.6 gallons
Mike used the most
Answer:
![P(A\cup B)= 0.875](https://tex.z-dn.net/?f=P%28A%5Ccup%20B%29%3D%200.875)
Step-by-step explanation:
From the diagram, none of the students play both instruments.
This means the two events are mutually exclusive.
![P(A\cup B)=P(A)+P(B)](https://tex.z-dn.net/?f=P%28A%5Ccup%20B%29%3DP%28A%29%2BP%28B%29%20)
The number of people playing instruments is 20.
![P(A\cup B)= \frac{20}{40} + \frac{15}{40}](https://tex.z-dn.net/?f=P%28A%5Ccup%20B%29%3D%20%5Cfrac%7B20%7D%7B40%7D%20%20%2B%20%20%5Cfrac%7B15%7D%7B40%7D%20)
![P(A\cup B)= \frac{35}{40}](https://tex.z-dn.net/?f=P%28A%5Ccup%20B%29%3D%20%5Cfrac%7B35%7D%7B40%7D%20)
![P(A\cup B)= 0.875](https://tex.z-dn.net/?f=P%28A%5Ccup%20B%29%3D%200.875)
The value of 8 in 58.2 is 8 ones.
The place value of 1/10 of a value in the ones place is 8 tenth.
Therefore, from the given options, the length that has an 8 with a value of 1/10 the value of the 8 in 58.2 centimeters is 209.86cm
B.) y=0, because here, the slope is zero but it rests on the x-axis thus yielding an infinite amount of touching
Answer:
y=4, x=-5
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
Well, we could merge the two equations together to do as shows:
4(2y-13)-3y=-32
8y-52-3y=-32
5y-52=-32
5y=20
y=4
To find x, we'd do
4x-3(4)=-32
4x-12=-32
4x=-20
x=-5
