43,000 in scientific notation is 4.3 x 10^4
Answer:
9.1 is the nearest tenth
9.11 to the nearest hundredth
just slightly to the right of 9.1
Step-by-step explanation:
sqrt(83)
sqrt(81) = 9
So we know that it is slightly greater than 9
9.1*9.1 =81.81
9.2*9.2=84.64
9.1 is closer
9.11 * 9.11 =82.9921
9.12 * 9.12 =83.1744
9.11 is closer
Easy! just compare then cross multiply 70:1 × 10:4 because you need to use the negative reciprocal of either one to create division with ratios/fractions
Answer:
1 or -9, depends on the problem, see below.
Step-by-step explanation:
-11--7+5
Two negatives make a positive so our new equation is:
-11+7+5
-11+7 is -4, so:
-4+5
And this leaves us with:
1
But I saw there was a parentheses, was it misplaced or was one not added? If one was not ended to the end, then the answer would be different.
(-11)-((-7)+5)
-7+5 is negative 2, so:
-11-(-2)
Once again, two negatives make a positive, so our new equation would be:
-11+2
Which gets us:
-9
9 is 1/10 of 90 because if you add 1 zero it is 90
