Rank the following in order from most precise to least precise.
1500 grams
8.43 inches
1580 meters
5.426 seconds

Answers

Answer:

1st most = 8.43 inches

2nd most = 5,426 Seconds

3rd most = 1580 meters

4th most = 1500 grams

Step-by-step explanation:

8.43 inches = 0.7025 feet is most precise as it rounded to 0.7 feet it wouldn't be precise enough.

5,426 Seconds =  01:30:26. hrs mins sec can be converted.

1580 meters = 1.58 km = 158000cm  hasn't been properly converted as zeros get lost.

1500 grams = 1.5kg hasn't been precisely converted as zeros get lost.

Oliver lives in a state with no state income tax. He pays $180 in payroll tax each week. If the federal income tax is 0.75 of the payroll tax, how much are the other taxes?

Answers

Answer:

The other taxes are $135.

Step-by-step explanation:

From the information provided, you know that Oliver pays $180 in payroll tax and that the federal income tax is 0.75 of the payroll tax, so in order to find how much are the other taxes you have to calculate the 0.75 of the payroll tax Oliver pays:

180*0.75=135

According to this, the answer is that the other taxes are $135.

if MN=NQ and MQ=QR=RP, calculate for x​

Answers

Answer:

C. 18°

Step-by-step explanation:

Refer to attached diagramGiven MN = NQ MQ = QR = RPNMR = 3xQMR = xTo findValue of xSolutionMN = NQ  ⇒ ∠MRN = ∠QMN = 3x+x = 4xMQ = QR ⇒ ∠MRQ = ∠QMR = x

RQP is exterior angle of ΔMQR ⇒

∠RQP = x + x = 2x

QR = RP ⇒

∠RPQ = ∠RQP = 2x

∠QRN is exterior angle of ΔQRP ⇒

∠QRN = 2x + 2x = 4x∠MRN = ∠QRN - ∠QRM = 4x - x = 3x

∠MRN = ∠NMR = 3x ⇒

NR = MQ

NR = MQ ⇒

∠NQR = ∠QRN = 4x

We now have a straight angle MQP:

∠MQP = ∠MQN + ∠RQN + ∠RQP180° = 4x + 4x + 2x10x = 180°x = 18°

Correct choice is C

Can someone please solve this it's very important thank you

So basically you have the equation y=6/x-2 and as it shows you in the example on the bottom of the page, you plug in the X values for X and whatever you get will be the Y on the other side. For example the first one is already done for you so in the second one you take the next X which is -3 and plug it into your equation. Y=6/(-3)-2 and that would reduce to Y=6/-5 and you can either put that for your next answer or convert it into a decimal. (This example is for the second answer in the Y column)
