Answer:

The correct answer is option C.

Step-by-step explanation:

Precision is defined as the closeness of two or more measurements to each other.This is how much close are the series of measurements of a same object to each other.

For example : If we measure volume of water in flask which comes out to be 2 mL and again on measuring for the number of times we get same value of 2 mL. Hence, this measurement will said to be precise.

A scale measures weight to the nearest 0.5 lb.So, from the given options the measurement which is appropriate to the given precision scale is 140.5 lbs.

What is the value of y?
nata0808 [166]

Answer: y = 16.5

Step-by-step explanation:

We would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Considering triangle BCD,

BD² = 14² - 8²

BD² ° 196 - 64 = 132

BD = √132

Considering triangle ABD,

AB² = BD² + y²

AB² = (√132)² + y²

AB² = 132 + y²- - - - - - - - - - 1

Considering triangle ABC,

(8 + y)² = AB² + BC²

(8 + y)² = AB² + 14²

(8 + y)² = AB² + 196

AB² = (8 + y)² - 196- - - - - - - -2

Substituting equation 1 into equation 2, it becomes

132 + y² = (8 + y)² - 196

y² - (8 + y)² = - 196 - 132

y² - (64 + 16y + y²) = - 328

y² - 64 - 16y - y2 = - 328

- 16y = - 328 + 64

- 16y = - 264

y = - 264/- 16

y = 16.5

PilotLPTM [1.2K]

Answer:

C. $40,000

Step-by-step explanation:

Basic salary = $500

Expected earning this week = $2,500

Expected commission on appliance sales = $2,500 - $500 = $2,000

% commission = 5% = 0.05

Appliance sales = $2,000/0.05 = $40,000

What is the length of segment TQ?
oksano4ka [1.4K]

Answer: 14

Step-by-step explanation:

We know that \triangle SRV \con \triangle QRV by SAS, so this means QV=SV by CPCTC. Hence, 4x-1 \longrightarrow x=4.

We also know that \triangle STR \cong \triangle QTR by SAS, so this means TS=TQ by CPCTC. Since TS=3x+2=3(4)+2=14, <u>TQ=14.</u>
