Which Expression Is Equivalent To (4.5x10^2) + (6.0x10^3) And Written In Scientific Notation? A. 1.05

Answers

Answer 1
Your answer for this problem is c
Answer 2

The value of the expression (4.5 x 10²) + (6.0x10³) is 6.45 x 10³. Therefore, the correct option is C.

Scientific notation:

The given expression is the sum of two numbers written in scientific notation.

[tex](4.5\times 10^2)+(6.0\times 10^3)[/tex]

It can be written as:

[tex](0.45\times 10\times 10^2)+(6.0\times 10^3)[/tex]

[tex]=(0.45\times 10^3)+(6.0\times 10^3)[/tex]

[tex]=(0.45+6.0)\times 10^3[/tex]

[tex]=6.45\times 10^3[/tex]

The required expression in scientific notation is [tex]6.45\times 10^3[/tex].

Therefore, the correct option is C.

Which sequence of transformations creates a similar, but not congruent, triangle?

A) Rotation and translation
B) Reflection and rotation
C) Dilation and rotation
D) Translation and reflection

Answers

Answer:

C) Dilation and rotation

Step-by-step explanation:

Dilation changes the size of the shape (how big or small the shape is), rather then changing the shape itself (into a completely different shape). The other options are transformations, but they only move the shape along the graph, nothing else.  Hope this helps!

help! Container ships sail all over the world to deliver cargo from port to port. Even though such ships can
weigh as much as 400,000 tons, they stay afloat because of the buoyant force exerted on them by the
water.
Below is a diagram of a container ship floating in the water. Its weight is represented by a downward
arrow and a negative number because the weight exerts a downward force on the boat. The buoyant
force of the water balances out the weight of the ship, so the ship can float. Describe an arrow that
would represent the buoyant force. What value should be associated with this arrow? Explain how this
situation relates to the concept of combining a number with its additive inverse.

Answers

Answer:

An object that weighs 100 tons and is floating is displacing exactly 100 tons of the fluid, and the buoyant force on it is 100 tons. The vertical forces on it are balanced (add up to zero), and that's why it isn't accelerating up or down.

-2 1/4 / (-1 1/2) =

A) 1 1/2

B) -1 1/2

C) 3 3/8

D) -3 3/8

Answers

Answer:

A) 1 1/2

Step-by-step explanation:

First, make sure both of the fractions are improper fractions. -2 1/4 will become -9/4 and -1 1/2 becomes -3/2. Then we do the keep, switch, flip trick and get -9/4 X -2/3 and multiply across. Since we have two negatives, the answer becomes positive. When we multiply across we get 18/12, then we reduce and get 1 6/12 which is the same as 1 1/2.

Answer: 18/12=1 3/12=1 1/4

Step-by-step explanation:-2 1/4=-9/4   -1 1/2=-3/2 keep the first change /to* flip the last fration

C. 0.5 meters

D. -0.5 meters

E. -1.3 meters

F. -1.8 meters

Answers

Answer: 1.3 Meters or B

Step-by-step explanation:

To answer this question, it must be noted first that the reference points of the given distances in this item is (1) the surface of the water and (2) the feet. We are given with the distance from the hand to the feet, 1.8 m, and from the feet to the surface of the water, 0.5 m. To get the distance from the hands to the surface of the water, we just have to subtract the given distances giving us an answer of 1.3 m.

Answer:

e. -1.3 meters

Step-by-step explanation:

subtract 1.8 by 0.5 and you get 1.3 since youre below water level youd put - in front of 1.3 since its negative
