20
u get this by doing 4 times 5 and then doing 5 times 4 because they both equal the same number

Answer:

3 hours: 38,250

1 day: 122,440

I’m not sure if this is exactly right, my brain gave out half way. Someone check my answer pls

Step-by-step explanation:

3 hours: 3 x 60= 900

900 divided by 20= 450

450 x 85 = 38,250

1 day: 24 x 60 = 1440

1440 x 85 = 122,440

A palm tree is supported by two guy wires as shown in the diagram below. Which trig expression can be used to find the height on

Volgvan

Answer:

D. $tan(30^\circ+45^\circ)$ is the correct answer.

Step-by-step explanation:

The given situation can be represented as a figure attached in answer area.

B is the base of tree.

C is the base of wires.

A and D are the end of 2 wires supporting the tree.

$\angle DCB =45^\circ\\\angle ACB =75^\circ\\$

Here, we need to find the Height of the tree which is represented the by side AB.

and we are given that bases of wires and tree base are at a distance 4 ft.

i.e. side BC = 4 ft

If we look at the $\triangle ABC$ , we are given the base BC and the $\angle ACB$ , and the perpendicular is to be find out.

We can use trigonometric identity:

$tan\theta =\dfrac{Perpendicular}{Base}$

$tan 75^\circ = \dfrac{AB}{BC}\\\bold {tan (45+30)^\circ }= \dfrac{AB}{4}\\\Rightarrow AB = \bold {tan (45+30)^\circ } \times 4 = 14.93\ ft$

Hence, D. $tan(30^\circ+45^\circ)$ is the correct answer.

Find the number if:

Paraphin [41]

Answer:

162 and $\frac{5}{2}$

Step-by-step explanation:

To find the original number multiply by the reciprocal of the multiplier, that is

90 × $\frac{9}{5}$ = $\frac{810}{5}$ = 162

------------------------------------------------------------------------

Similarly

Change the mixed number into an improper fraction

5 $\frac{5}{6}$ = $\frac{35}{6}$ , then

$\frac{35}{6}$ × $\frac{3}{7}$ ( cancel 35 and 7 by 7 / cancel 6 and 3 by 3 )

= $\frac{5}{2}$ × $\frac{1}{1}$

= $\frac{5}{2}$
