2 x 1/4 is the same as 1/4 + 1/4

When you multiply something, you are adding one value the amount of the other value, meaning if you have 4*x, it is equal to x+x+x+x. Using this, we can determine that 2*(1/4) is equal to (1/4)+(1/4), or answer choice A.

Write parametric equations of the line through the points (7,1,-5) and (3,4,-2). please use the first point as your base-point w

Roman55 [17]

Given:

A line through the points (7,1,-5) and (3,4,-2).

To find:

The parametric equations of the line.

Solution:

Direction vector for the points (7,1,-5) and (3,4,-2) is

$\vec {v}=\left$

Now, the perimetric equations for initial point $(x_0,y_0,z_0)$ with direction vector $\vec{v}=\left$ , are

$x=x_0+at$

$y=y_0+bt$

$z=z_0+ct$

The initial point is (7,1,-5) and direction vector is $\vec {v}=\left$ . So the perimetric equations are

$x=(7)+(-4)t$

$x=7-4t$

Similarly,

$y=1+3t$

$z=-5+3t$

Therefore, the required perimetric equations are $x=7-4t, y=1+3t$ and $z=-5+3t$ .

The new balance of a charge account is $145.00. The minimum payment is $20.00. If the interest rate is 1.5%, how much will the n

juin [17]

The balance is $145 but after one makes he minimum payment of $20, there is $125 left to pay. However interest is added before the next month’s bill is generated.

Remember that percent means out of 100. 1.5% means 1.5/100 = .015

To find 1.5% of 125 we multiply (.015)(125) = 1.875 But as this is money the interest is rounded to two decimal places and so is $1.88

We add this to 125 to get next month’s balance which is 125 + 1.88 = $126.88

What is 645/87 rounded to the nearest integer?

Vlad1618 [11]

Answer:

Step-by-step explanation:

Firstly, let us divide the two numbers as so-

$645/87=7.41379310345\\$

To round a number to the nearest integer, look at the decimal places.

Here we have .41 - The 4 is less than 5, so it cannot round the ones place to 8.

So our answer here is 7.
