Which expressions are equivalent to (5⋅x)⋅3 ? Drag and drop the equivalent expressions into the box

dimaraw [331]

Answer:

First option.

Third option.

Fourth option.

Step-by-step explanation:

For this exercise is important to remember that equivalent expression have the same value.

Then given the following expression provided in the exercise:

$(5x)3$

You can find equivalent expression by:

- Changing the position of $3$ :

$3(5x)$ (This matches with the first option)

- Solving the multiplication indicated. Then:

$(5x)3=15x$ (This matches with the fourth option)

- Writting $x3$ inside the parentheses:

$5(x3)$ (This matches with the third option)

Consider a steel guitar string of initial length L=1.00 meter and cross-sectional area A=0.500 square millimeters. The Young's m

Goshia [24]

Answer:

15mm

Step-by-step explanation:

we are looking for extension

To get Extension you need the original length and the strain both of which you are given

initial length L = 1.00m

the area A = 0.5mm² = 0.5 mm² = 0.5 x 10⁻⁶ m² ( we are changing to metres squared)

E = 2.0 x 10¹¹ n/m², Young's modulus

P = 1500N, the applied tension

Now to Calculate the stress.

σ = P/A (force/area) = (1500 N)/(0.5 x 10⁻⁶ m²) = 3 x 10⁹ N/m²

Also, Let β = the stretch of the string.

Then the strain is

ε = β/L (extension/ original length)

By definition, the strain is ε = σ/E = (3 x 10⁹ N/m²)/(2 x 10¹¹ N/m²) = 0.015

Therefore β/(1 m) = 0.015β = 0.015 m = 15 mm

Answer: 15 mm

Chad used the table to show the ratios of the different types of sports game cards that he owns. For every 2 offense cards, he o

Travka [436]

Answer:

The graph that has the points (2,4) and (4,8) should be the answer.

Step-by-step explanation:

This is the answer because if you see the ratio 2:4, that means that for every 2 offense cards there are 4 defense cards. As you continue to go up it would be (4,8), (6,12), (8,16), and so forth.

Answer:

Area = 45 sq ft

Step-by-step explanation:

Scale conversion:

2 inches = 6 feet

5 inches = 15 feet

Area = 1/2 base times height

Area - 1/2 x 6 x 15

Area = 45 ft squared
