The product of (-1/4)(-3/7) is:

(-1/4)(-3/7)

As both are negative, the outcome is posostive.

1/4 × 3/7

=3/4×7

=3/28

Therefore the answer is C.3/28.

Hope it helps!

Answer: 3/28

Step-by-step explanation: First of all, we have two negative fractions we are multiplying. Whenever multiplying or dividing two negative fractions, the answer is always positive.

Now, to get our answer, we multiply the numerators and denominators together and but the numerator product over the denominator product as follows.

$-\frac{1}{4} (-\frac{3}{7}) = \frac{3}{28}$

3/28 cannot be further simplified, so that is your answer.

Find an equation for the line with the given properties. Express your answer using the general form or the slope-intercept form

Damm [24]

Answer:

$y=-3x+4$

Step-by-step explanation:

To get the equation in the slope-intercept form first, put the equation in slope-point form using the information given. The slope-point form is $y-(-2)=-3(x-2)$ . Then solve for y.

Distribute -3 to $(x-2)$ ,

$y-(-2)=-3x+6$

Then, add -2 to both sides,

$y=-3x+4$

This is your final answer; the slope is -3 and the y-intercept is 4. There are also a few other ways to solve but I find this the easiest.

Fill in Sin, Cos, and tan ratio for angle x. <br> Sin X = 4/5 (28/35 simplified)

Fantom [35]

Answer:

Given: $\sin(x) = (4/5)$ .

Assuming that $0 < x < 90^{\circ}$ , $\cos(x) = (3/5)$ while $\tan(x) = (4/3)$ .

Step-by-step explanation:

By the Pythagorean identity $\sin^{2}(x) + \cos^{2}(x) = 1$ .

Assuming that $0 < x < 90^{\circ}$ , $0 < \cos(x) < 1$ .

Rearrange the Pythagorean identity to find an expression for $\cos(x)$ .

$\cos^{2}(x) = 1 - \sin^{2}(x)$ .

Given that $0 < \cos(x) < 1$ :

$\begin{aligned} &\cos(x) \\ &= \sqrt{1 - \sin^{2}(x)} \\ &= \sqrt{1 - \left(\frac{4}{5}\right)^{2}} \\ &= \sqrt{1 - \frac{16}{25}} \\ &= \frac{3}{5}\end{aligned}$ .

Hence, $\tan(x)$ would be:

$\begin{aligned}& \tan(x) \\ &= \frac{\sin(x)}{\cos(x)} \\ &= \frac{(4/5)}{(3/5)} \\ &= \frac{4}{3}\end{aligned}$ .

Mike hiked to a lake in 4.5 hours at an average rate of 4 1/5 miles per hour. Pedro hiked the same distance at a rate of 4 3/5 m

ExtremeBDS [4]

Answer:

distance = rate x time

3 and 1/5 = 3.2 and 3 and 3/5 = 3.6

distance = 3.2 x 4.5 = 14.4

14.4 = 3.6 x T

T = 14.4 / 3.6 = 4 <--- Pedro's time

The width of a DVD case is the same as the width of a

konstantin123 [22]

Answer:

12m

Step-by-step explanation:

Given that the area of the square DVD case is 144 square cm

Since Area = L²

144 =L²

L = √144

L = 12m

Since the width of the DVD and its case are the same, hence the with of the DVD is also 12m
