I don’t understand how to do this? Can someone explain this to me?

To round to the nearest thousand, we check the digit in the hundreds place. If it is less than 5, we round down, else we round up to the next thousand.

In this case, the digit in the hundreds place is "6" and "6" is 5 or more, so we round up to the next thousand.

Determine the equation of the line passing through the points (3,1) and (5,−1).

katrin [286]

Answer:

y=-x+4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-1)/(5-3)

m=-2/2

m=-1

y-y1=m(x-x1)

y-1=-1(x-3)

y-1=-x+3

y=-x+3+1

y=-x+4

Given: LM ∥ KN LP ⊥ KN , KL = MN KN = 30, LM = 20 m∠KLM=126° Find: LP

Ronch [10]

An angle is produced at the point where two or more lines meet. Thus the value of LP required in the question is approximately 14.

Two lines are said to be perpendicular when a measure of the angle between them is a right angle. While parallel lines are lines that do not meet even when extended to infinity.

From the question, let the length of LP be represented by x.

Thus, from the given question, it can be deduced that;

LM ≅ PN = 20

KP = KN - PN

= 30 - 20

KP = 10

LP = x

Also,

<MLP is a right angle, so that;

< KLP = < KLM - <PLM

= 126 - 90

<KLP = $36^{o}$

So that applying the Pythagoras theorem to triangle KLP, we have;

Tan θ = $\frac{opposite}{adjacent}$

Tan 36 = $\frac{10}{x}$

x = $\frac{10}{Tan 36}$

= $\frac{10}{0.7265}$

x = 13.765

Therefore the side LP ≅ 14.

Write and solve a word problem for the expression 8 divided by 1/2.

galben [10]

Answer:

if 8 times 1/2 is 4 then what does 8 divided by 1/2 equal. 16 is the answer

Step-by-step explanation:

8 divided by 0.5(1/2) is 16

if you multiply a decimal with a number it will be a smaller number as if you divide it will be a bigger number

Twice a number (z) added to 21 is equal to 9 times the number added to 7. What is the number?

pickupchik [31]

Answer:

The number is 2

Step-by-step explanation:

Twice a number (z) = 2*z = 2z

Twice a number (z) added to 21 = 2z + 21

9 times the number added to 7 = 9z + 7

9z + 7 = 2z + 21

Subtract 2z form both sides

9z - 2z + 7 = 21

7z + 7 = 21

Subtract 7 from both sides

7z = 21 - 7

7z = 14

Divide both sides by 7

z = 14/7

z = 2
