Round 3.75 to the nearest whole number

2 answers:

4 0

The nearest hole number would be 4 , if it is .5 and above then it gets rounded up to the next number and if it is .4 or less that you round it to the whole number

Because your round the last number out of 75 and the 5 makes the number change and move up. Anything that’s bigger then 5 changes if it’s below it stays and gets lower. 3.75 is like saying 3.80 but as a whole number you would use 4 that way you don’t have a decimal in whatever your doing gets you confused.

In triangle ABC angle A=45 angle B =40 and a=7.Which equation should you solve to find b?

coldgirl [10]

We have been given that in triangle ABC angle A=45 angle B =40 and a=7. We are asked to find the equation that we can use to solve for 'f'.

We have two angles and opposite sides to these angles.

We will use Law of Sines to solve our given problem.

$\frac{a}{\sin(A)}=\frac{b}{\sin(B)}=\frac{c}{\sin(C)}$ , where a, b and c are opposite sides corresponding to angles A, B, and C respectively.

The angle opposite to side b is 40 degrees and angle opposite to side a is 45 degrees.

Upon substituting these values in Law of Sines, we will get:

$\frac{7}{\sin(45^{\circ})}=\frac{b}{\sin(40^{\circ})}$

Therefore, our required equation would be $\frac{7}{\sin(45^{\circ})}=\frac{b}{\sin(40^{\circ})}$ .

The midpoint of AB is (3,2). If point is is located at(8,4) what are the coordinates of point B

Dmitry [639]

Step-by-step explanation:

8-3 = 5,

3-5 = -2 = the x coordinate of B

-2-4 =-6,

-2-6 =-8 = the y coordinate of B

(-2,-8) is the point B

A is 5 to the right of the midpoint, so B is 5 to the left of the midpoint

A is 6 up from the midpoint so B is 6 down from the midpoint
