Round 81.139 to the nearest tenth

Answers

Answer 1

Answer: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).

81.139 ≈ 81.1

Answer 2

Answer: the first place after the decimal place is the tenth's place, then next is the hundreth's and so on

when rounding, if the number is 5 or more then round up , if less than 5, round down
exg\
.5 runded up=1
.4 rounded would be 0

so 81.139
disregard the 9
81.13
3 is less than 5
81.10

Answers

In the first product the numerator of the fraction is greater than the denominator, therefore the fraction is greater than 1. On the other hand in the second product the numerator of the fraction is smaller than the denominator, therefore the fraction is smaller than one. That means the first product is greater than the second one.

figure out which fraction is larger first by making a mixed number:9 1/6 them find least common denominator between 6 and 10 to compare the two fractions. once you got that which numerator is larger. if that made no since sorry

What is the pair for p(x)=(x-2)^2-2

Answers

Answer:

(2,-2)

Step-by-step explanation:

Assuming you are looking for the pair that represents the vertex of the polynomial

$p(x) = {(x - 2)}^(2) - 2$

Then we compare to the vertex form:

$p(x) = a {(x - h)}^(2) + k$

whose vertex is given by x=h, y=k.

By comparing, we have x=2 , and y=-2.

The ordered pair representing the vertex is (2,-2)

What is the distance, in feet, across the patch of swamp water?

Answers

Answer:

Therefore the distance across the patch of swamp water is 50 ft

Step-by-step explanation:

Given:

VW = 100 ft

WX = 60 ft

XZ = 30 ft

To Find:

ZY = l = ?

Solution:

In Δ VWX and Δ YZX

∠W ≅ ∠ Z …………..{measure of each angle is 90° given}

∠VXW ≅ ∠YXZ ..............{vertically opposite angles are equal}

Δ ABC ~ Δ DEC ….{Angle-Angle Similarity test}

If two triangles are similar then their sides are in proportion.

$(VW)/(YZ) =(WX)/(ZX) =(VX)/(YX)\ \textrm{corresponding sides of similar triangles are in proportion}\n$

On substituting the given values we get

$(100)/(l) =(60)/(30)\n\nl=(3000)/(60)=50\ ft$

Therefore the distance across the patch of swamp water is 50 ft

Paul owes Paula 35 cents and has a pocket full of 5-cent coins, 10-cent coins, and 25-cent coins that he can use to pay her. What is the difference between the largest and the smallest number of coins he can use to pay her?
