Sophia used the Order of Operations to simplify 4(5 - 2) to 4x3.

Mathematics

Alchen [17]3 years ago
5 0

Answer:

  • Yes

Step-by-step explanation:

<u>Order of operations, use the operation within the parenthesis:</u>

  • 1) 5 - 2 = 3
  • 2) 4*3 = 12

<u>Distributive property, a(b + c) = ab + ac:</u>

  • 1) 4*5 - 4*2 = 20 - 8
  • 2) 20 - 8 = 12

Both ways are correct and lead to same result

Abcd is a rectangle if DB=26 and DC=24 find bc
Anettt [7]
Let's solve this problem step-by-step.

STEP-BY-STEP EXPLANATION:

Let's first establish that triangle BCD is a right-angle triangle.

Therefore, we can use Pythagoras theorem to find BC and solve this problem. Pythagoras theorem is displayed below:

a^2 + b^2 = c^2

Where c = hypotenus of right-angle triangle

Where a and c = other two sides of triangle

Now we can solve the problem by substituting the values from the problem into the Pythagoras theorem as displayed below:

Let a = BC

b = DC = 24

c = DB = 26

a^2 + b^2 = c^2

a^2 + 24^2 = 26^2

a^2 = 26^2 - 24^2

a = square root of ( 26^2 - 24^2 )

a = square root of ( 676 - 576 )

a = square root of ( 100 )

a = 10

Therefore, as a = BC, BC = 10.

If we want to check our answer, we can substitute the value of ( a ) from our answer in conjunction with the values given in the problem into the Pythagoras theorem. If the left-hand side is equivalent to the right-hand side, then the answer must be correct as displayed below:

a = BC = 10

b = DC = 24

c = DB = 26

a^2 + b^2 = c^2

10^2 + 24^2 = 26^2

100 + 576 = 676

676 = 676

FINAL ANSWER:

Therefore, BC is equivalent to 10.

A lab technician is dividing a cell that has a diameter of 4.32×10^-4 millimeters. Each of the new cells has a diameter measurin
RideAnS [48]

Answer:

2.16 \times  {10}^{ - 4}

Step-by-step explanation:

The lab technician is dividing a cell that has a diameter of

4 .32 \times  {10}^{ - 4}

The new cells has a diameter that is half of the diameter of the original cell.

The diameter of the new cell is given as:

\frac{4.32 \times  {10}^{ - 4} }{2}

Rewrite the numerator in standard notation:

\frac{0.000432}{2}

= 0.00216

We rewrite in scientific notation to obtain:

2.16 \times  {10}^{ - 4}
