Which expression is equivalent to (4.5x10^2) + (6.0x10^3) and written in scientific notation?

A. 1.05 x 10^6
B 2.7 x 10^6
C. 6.45 x 10^3
D. 10.5 x 10^5

Answers

Your answer for this problem is c

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.

help me again. i need help. thx 4 helping

Answers

Answer:

16 square units

Step-by-step explanation:

The formula for the area of a right triangle is ab/2 (a and b both being legs).

First, we find the legs' length which is MK and JK.

Since both points J and K are on the same y level, we look at the X coordinates and see how far apart they are.

Since both points M and K are on the same x level, we look at the Y coordinate.

M is 4 points away from K, so the leg MK is 4 units long.

J is 8 points away from K, so the leg JK is 8 units long.

Plug this into the formula and we get

[tex]\frac{4*8}{2}[/tex]

[tex]\frac{32}{2} = 16[/tex]

A map has a scale of 3 cm : 18 km. If Riverside and Smithville are 54 km apart then they are how far apart on the map?
rainliest plz solve

Answers

Riverside and Smithville will be 9 km apart on the map. For every 6 km they will be 1 cm apart on the map.

54 km is 3 times of 18km and 3 times of 3 cm is 9 cm. So, Riverside and Smithville are 9 cm apart on the map.

Ratio and proportion:

Important information:

The given scaling ratio is 3 cm : 18 km.Riverside and Smithville are 54 km apart.

We need to find the distance between Riverside and Smithville in the map.

Let x cm be the distance between Riverside and Smithville in the map. The distance in the map and the actual distance are always proportional.

[tex]\dfrac{x}{54}=\dfrac{3}{18}[/tex]

[tex]x=\dfrac{3}{18}\times 54[/tex]

[tex]x=9[/tex]

Therefore, Riverside and Smithville are 9 cm apart on the map.
