Mathematics

Nata [24]3 years ago

Answer:

The correct answer is A.

Step-by-step explanation:

Scientific notation has to be a number between 1 and 10, so we know b and d are out. Then, you have to count how many places you'd have to move to get to the end of the number. It's 10 jumps, so the correct answer would be 1.19*10^10.

Hope this helps!

What is the sum of 1 2/16 + .6 + (-½)

Mashutka [201]

Answer:

1 9/40

Step-by-step explanation:

Any calculator can tell you the sum is ...

1 + 2/16 + 0.6 - 1/2 = 1.225

The decimal fraction can be reduced, if you like:

225/1000 = (25)(9)/(25(40)) = 9/40

As a mixed number, the sum is 1 9/40.

Alternate solution

1 2/16 + 0.6 -1/2 = 1 1/8 + (6/10 -5/10) = 1 1/8 + 1/10

= 1 + (1/8 +1/10) = 1 +(5/40 +4/40) = 1 9/40

What is the equation of the line that is parallel to the line y − 1 = 4(x + 3) and passes through the point (4, 32)

Finger [1]

<span>y − 1 = 4(x + 3)
y - 1 = 4x + 12
y = 4x + 13, slope = 4
parallel lines, slope is the same so slope = 4
</span><span>passes through the point (4, 32)
</span>y = mx+b
b = y - mx
b = 32 - 4(4)
b = 32 - 16
b = 16

equation
y = 4x + 16
