Answer:
(7a+y)=(z-4)
Step-by-step explanation:
(7a+y)=z-4
(7a+y)=(z-4)
The number of times which the number 2 x 10-5 is greater than 4 x 10-12 is; 5 × 10⁶ times
To estimate how many times larger 2 x 10-5 is than 4 x 10-12 in the form of a single digit times an integer power of 10;
We must evaluate as follows;
- 2 x 10-5 divided by 4 x 10-12

Therefore; we have;
Since we are required to express the answer in the form of a single digit times an integer power of 10; we have;

Step-by-step explanation:
2(xy)^3
= 2(0.6 * 5)^3
= 2(3)^3
= 2 * 27
= 54
Answer:
92
Step-by-step explanation:
x= the ideal mark for his third test
100 + 63 + x/3 = 85
163+x=85x3
163 + x = 255
x=92
He would need to get at least a 92 to have the 85 average.
Answer:
the home is
5.83 blocks 31° North of west of the school
Step-by-step explanation:
Resolving the displacement to vertical and horizontal axis
Let north and south represent positive and negative vertical axis, also east and west represent positive and negative horizontal axis;
Vertical axis; , 2 blocks south to visit her aunt, then 5 blocks north to go home
Ry = -2 + 5
Ry = +3
Horizontal axis; 5 blocks west to the grocery store
Rx = -5
Resultant distance = R = √(Rx^2 + Ry^2)
R =√(-5^2 + 3^2)
R = √34
R = 5.83 blocks
For the direction;
∅ = arctan(Ry/Rx) = arctan(3/5)
∅ = 31°
Therefore, the home is
5.83 blocks 31° North of west of the school.
