Answer:

D) -2.45*10^2, 6.987, \sqrt{93}

Step-by-step explanation:

The smallest number is -2.45*10^2 even though it's multiplied with 10^2 it's still has the negative sign

then comes  6.987 because the root of \sqrt{93} is equal to 9.6 approximately so the correct answer is D

Three more than twice a number x is 15. Determine the value of x.
GuDViN [60]

Answer:

Pretty sure the answer would be x=6

Step-by-step explanation:

The number (x) in: "3 more than twice a number is 15" is what we are solving here.

In other words, you are looking for a number (x) that if you multiply it by two (same as twice) and then add 3, you get 15.

To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 15

Then you solve the equation by subtracting 3 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 3 = 15

2x + 3 - 3 = 15 - 3

2x = 12

2x/2 = 12/2

x = 6

Suppose that a toy car moving at 7.20 m/s is going around a track that has a radius of 1.50 m. What acceleration will the car ex
wel

Answer:

a=34.56\ m/s^2

Step-by-step explanation:

Given that,

Speed of a toy car, v = 7.2 m/s

Radius of the circular track, v = 1.5 m

We need to find the acceleration of the car. When an object moves in a circular path, it will have centripetal acceleration. It can be given as follows :

a=\dfrac{v^2}{r}\\\\a=\dfrac{(7.2)^2}{1.5}\\\\=34.56\ m/s^2

So, the centripetal acceleration of the toy car is 34.56\ m/s^2. Hence, the correct option is (c).

X(21)+x(4)=300 I need solving
Genrish500 [490]

Answer:

12

Step-by-step explanation:

21x + 4x = 300         Put brackets around the first two terms.

(21x + 4x) = 300        Pull the x outside the brackets. Use the distributive property.  Combine the left

25x = 300                 Divide by 25

25x/25=300/25        Do the division

x = 12
