Answer:

4 hours 55 minutes

Step-by-step explanation:

Time, speed, and distance are related by ...

t = d/s

t = (177 mi)/(36 mi/h) = 4 33/36 h = 4 11/12 h

The fractional part of this time is ...

11/12 hour is (11/12)(60) = 55 minutes

The van will take 4 hours and 55 minutes to travel a distance of 177 miles.

Answer:

160 m

Step-by-step explanation:

For the 15-deg angle, h is the opposite leg.

The hypotenuse is 628 m.

The trigonometry ratio that relates the opposite leg and the hypotenuse is the sine.

sin A = opp/hyp

$\sin 15^\circ = \dfrac{h}{628~m}$

$h = 628~m \times \sin 15^\circ$

$h = 162.54~m$

Rounded to 2 significant figures:

h = 160 m

Based on experimental data, the function T(x) = -3(x − 4)3 + 10 models the temperature of a special substance after being placed

If I assume you meant

$-3(x-4)^{2}+10$

Then the answer is at 4 minutes. This is just the vertex form of the parabola which is

$y=a(x-h)^{2}+k$

where (h,k) is the vertex. h = 4 so the vertex is at 4 in the x-axis, or in the context of the problem it means at 4 minutes.

Answer:

Option C is correct

Step-by-step explanation:

In similar triangles corresponding sides are in same ratio.

Notice that sides b and q are corresponding ( they are opposite equal angles) and so are a and p
