Answer:

her degree of accuracy in measurement is 0.05 cm (Option D)

Step-by-step explanation:

The degree of accuracy in the measurement of the botanist depends on the instrument used.

For a length of 3.56 centimeters, it shows that the length of the tomato seedling was measured using meter rule or tape.

Meter rule is graduated in 1 mm or 0.1 cm. The estimated uncertainty in measurement using meter rule is half of its graduation i.e ( ¹/₂ of 0.1 cm = 0.05 cm).

If the botanist measured the length of tomato seedling as 3.56 centimeters, then her degree of accuracy in measurement is 3.56 cm ± 0.05 cm.

Therefore, her degree of accuracy in measurement is 0.05 cm (Option D)

While shopping, Dawn finds a backpack that she likes on the sale rack. Its original price is $60,

Nadya [2.5K]

No. Because 33 $ is the money deducted from the 60 $. Dawn bought everything for less than 60 $.

So, if Dawn purchases everything on the rack with a 30% discount and 15% coupon the total will indeed make 45%.

We have to take 100% - 45%= 55% to know the reduction number. Let's proceed to the calculations now.

100%= 60 $

1%=60/100

55%= 60/100 × 55 = 33 $

Now NOTE; 33 $ is the money reduced from the 60 $. So, logically, 33 $ isn't the amount which Dawn purchased the whole rack. 

To find the amount at which she purchased everything, we need to do,

60 $ - 33 $ = 27 $

If DB = 36 and AC = 3x - 3, what is the value of x?

algol13

Answer:

A.) 13

Step-by-step explanation:

Since DB =36, and AC is the same line, then AC = 36. The new equation is 36 = 3x - 3. Do inverse operation. Add 3 to both sides of the equation: 36+3=39 & -3+3=0. New equation is 39=3x. Finally divide. 39/3= 13.
