ake and Nico both measured their thumbs. Jake’s thumb is 55 millimeters long. Nico’s thumb is 5.7 centimeters long. Who has the
qaws [65]

Answer:

Nico

Step-by-step explanation:

We have to convert both to the same units! Think about the units: we have millimeters and centimeters. There are 10 millimeters in a centimeter, so

55 mm = 5.5 cm

We just had to move the decimal point!

Now compare the two measurements in cm. 5.5 and 5.7: which is greater? Look at the tenths place: 5<7, so 5.7 is greater and Nico’s thumb is longer!

The index rises 4.9% over the course of the day. What is the value of the index at the end of the day? Round your answer to the
makvit [3.9K]

Answer: $70400

Step-by-step explanation:

Attached is the question:

Based on the information given in the question:

Value of Stock X = 5000 × $4.30 = $21500

Value of Stock Y = 2000 × $3.20 = $6400

Value of Stock Z = 8000 × $4.90 = $39200

Total Stock Value = $67100.

Since there's a 4.9% increase in value of index, the value of the index at end of the day will be:

= $67100 × (100% + 4.9%)

= $67100 × 104.9%

= $67100 × 1.049 =

= $70388

= $70400 approximately

What is the solution set to the equation (2x−4)(4x−5)=0
Misha Larkins [42]
First, distribute the parenthesis:
(2x - 4) (4x - 5) = 8x - 20
 \___\_/___/
       |       |
2x * 4x, 4 * 5
Then you add 20 to both sides
8x - 20 = 0
      +20 +20
8x = 20
Then you divide both sides by 8
\frac{8x = 20}{8}
x = 2.5

I think I did that right... I don't quite remember what a solution set is
