I think the answer is c I hope this help
Answer: Choice A
Point A is plotted 4 units to the right and 3 units above the origin. Point B is plotted 2 units to the right of and 1 unit above the origin. Point C is plotted 3 units to the right and 4 units above the origin
====================================================
Explanation:
The point A(4,3) means we start at the origin and move 4 units to the right and 3 units up. The x and y axis are separate number lines to mark a location
B(2,1) means we move 2 units to the right and 1 unit up
C(3,4) means we move 3 units to the right and 4 units up
Each time we plot a new point, we always start at the origin.
Answer:
a) 1.59967 * 10 ^-12
b) 7.52711497
c) 1.590778098 * 10^-1
Step-by-step explanation:
a= 3.47 x 10^-6,
b=4.61 x 10^-7,
c=5.52 x 10^-7
a) a*b = 3.47 x 10^-6* 4.61 x 10^-7
We multiply the numbers out front and add the exponents
(3.47*4.61) * 10^(-6+-7)
15.9967 * 10^-13
But this is not correct scientific notation, we need 1 number in front of the decimal. Move the decimal 1 place to the left and add 1 to the exponent
1.59967 * 10^(-13+1)
1.59967 * 10 ^-12
b) a/b = 3.47 x 10^-6/ 4.61 x 10^-7
We divide the numbers out front and subtract the exponents
(3.47/4.61) * 10^(-6- -7)
(3.47/4.61) * 10^(-6+7)
.752711497* 10^1
But this is not correct scientific notation, we need 1 number in front of the decimal. Move the decimal 1 place to the right and subtract 1 from the exponent
7.52711497* 10^1-1
7.52711497
c) c/a = 5.52 x 10^-7/3.47 x 10^-6
We divide the numbers out front and subtract the exponents
(5.52/3.47) * 10^(-7- -6)
(5.52/3.47) * 10^(-7+6)
1.590778098 * 10^-1
Answer:
x = 29
y = 6
Step-by-step explanation:
Let the two numbers be represented as x and y
x + y = 35
x = 5y - 1
Substitute x as 5y -1 in equation one
5y -1 + y = 35
5y + y -1 = 35
Add 1 to both sides
6y - 1 + 1 = 35 + 1
6y = 36
Divide both sides by 6
6y/6= 36/6
y = 6
Now substitute y as 6 in any of the equations to get x.
Using equation one ,
We have
x + y = 35
x +6 = 35
Subtract 6 from both sides
x + 6 - 6 = 35 - 6
x = 29
10 hours.
If you multiply 2 1/2 by 4, the product is 10.
