love history [14]3 years ago
5 0

Answer:

The simplification is done below.

Step-by-step explanation:

(\sin(\frac{\pi}{6})\cos(\frac{\pi}{4}) - \sin(\frac{\pi}{4})\cos(\frac{\pi}{6}))^{2}

=  (\frac{1}{2} \times \frac{1}{\sqrt{2}} - \frac{1}{\sqrt{2}} \times \frac{\sqrt{3}}{2})^{2}

=((\frac{1}{2\sqrt{2}}) \times (1 - \sqrt{3}))^{2}

= 0.125 \times (1 - (2 \times \sqrt{3}) +3)

Help please <br>hdjsjskssj
Serga [27]

For every 5 green picks, 2 are orange. Adding 5+2 makes 7. 21/7 = 3

There are 3 sets of 5 green 2 orange picks. So 2*3 = 6.


There should be 6 orange picks.


You can also just count. 5 + 2 = 7. Adding another 5 picks = 7 + 5 + 2 = 14. Another 5 picks, 14 + 5 + 2 = 21. Adding up the orange picks, which is the twos, we get 6.

Solve for the height (h) of this triangular prism if the volume is 1080. The
dexar [7]

Answer: 18

Step-by-step explanation:

Area of triangle = (0.5) × base(b) × height(h)

Base of triangle = 8

Height of triangle = 15

Area of triangle = (0.5) × 8 × 15 = 60

Volume of triangular prism = B × height

Where h = height

B = area of triangle

Volume of triangular prism = 1080

Find the height(h) of the triangular prism

Volume of triangular prism = B × height

1080 = 60 × h

h = 1080 / 60

h = 18

Simplify the expression <br> 4(-8x+5)-(-33x-26)=
Pavel [41]

Answer:

x+46

Explanation:

4(−8x+5)−(−33x−26)

Distribute the Negative Sign:

=4(−8x+5)+−1(−33x−26)

=4(−8x+5)+−1(−33x)+(−1)(−26)

=4(−8x+5)+33x+26

Distribute:

=(4)(−8x)+(4)(5)+33x+26

=−32x+20+33x+26

Combine Like Terms:

=−32x+20+33x+26

=(−32x+33x)+(20+26)

=x+46
