A sports store received a shipment of 400 baseball gloves, 30% were left-

noname [10]

280 right handed gloves. First, we'd need to find out the amount of left handed gloves. We do this by multiplying 0.3 (which is basically 30%) by the total number of gloves. This is because we are finding out 30% of the 400 gloves, and "of" represents multiplication. We get 120. Then, we subtract that number from 400 to get the amount of right handed gloves, which is 280. hope this helps :)

Use a calculator to find the value of t. Round to the nearest thousandth. T=ln 1.5-3

spin [16.1K]

Answer:

-2.595

Step-by-step explanation:

When inputting this function into your calculator, we need to be aware of a couple things:

1.) his is ln(1.5) - 3, and not ln(1.5-3). Negative numbers cannot be put into the natural log function.

2.) That is because lnx is another way of saying $log_{e}x$ . If you're having trouble finding ln on the calculator, use logx/loge (an odd rule that you'll learn soon from the looks of it.)

The equation of the line through (2,-5) and parallel to the line x+3y-9=0is:

djyliett [7]

Answer:

x + y = -13

Step-by-step explanation:

The equation of a line is y=mx+c

Line x+3y-9=0

Let's rearrange.

3y= -x+9

Divide both sides by 3.

3y/3 = -x/3 +9/3

y= -x/3 + 3

The gradient is the coefficient of x which is -1/3.

Therefore, m1 = -1/3

Where m1 is the gradient of the first line.

When two lines are parallel, their gradients are equal.

Therefore m1=m2

Where m2 is the gradient of the second line.

Therefore m2=-1/3

Now, we need to find c.

(2,-5)

Here, x=2, y=-5

y=mx+c

-5 = -1/3(2) + c

-5 = -2/3 + c

-5 + 2/3 = c

This can also be written as...

c = -5 +2/3

The LCM is 3.

The addition will give -13/3.

Now, let's create the equation We have m2 and c.

y = mx + c

y = -1/3(x) + (-13/3)

Take note of the signs, (+), and (-).

y = -x/3 - 13/3

Multiply both sides by 3 to remove the denominators.

(3)y = (3)-x/3 - (3)13/3

y = -x - 13

Or

x + y = -13

I hope you understand. Please give brainliest, thank, and rate 5 stars. thanks.
