Find the unknown side: V u 2.5 85 26

Mathematics
1 answer:
tia_tia [17]3 years ago
5 0

Answer:

u ≈ 5.7

Step-by-step explanation:

Using the Sine rule in Δ TUV, that is

\frac{t}{sinT} = \frac{u}{sinU} , substitute values

\frac{2.5}{sin26} = \frac{u}{sin85} ( cross- multiply )

u × sin26° = 2.5 × sin85° ( divide both sides by sin26° )

u = \frac{2.5sin85}{sin26} ≈ 5.7 ( to 1 dec. place )

A regular hexagonal prism has an edge length 12 cm, and height 10 cm. Identify the volume of the prism to the nearest tenth.
Alexeev081 [22]

Check the picture below.

so the volume will simply be the area of the hexagonal face times the height.

\textit{area of a regular polygon}\\\\ A=\cfrac{1}{4}ns^2\stackrel{\qquad degrees}{\cot\left( \frac{180}{n} \right)}~~ \begin{cases} n=\stackrel{number~of}{sides}\\ s=\stackrel{length~of}{side}\\[-0.5em] \hrulefill\\ n=6\\ s=12 \end{cases}\implies A=\cfrac{1}{4}(6)(12)^2\cot\left( \frac{180}{6} \right) \\\\\\ A=216\cot(30^o)\implies A=216\sqrt{3} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{area of the hexagon}}{(216\sqrt{3})}~~\stackrel{height}{(10)}\implies 2160\sqrt{3}~~\approx ~~3741.2~cm^3

A line that includes the points ( - 2, - 9) and ( - 6,n) has a slope of - 1. What is the value of n?
Genrish500 [490]

Write out the slope formula:

m = (change in y) / (change in x)

Here,

m = n-(-9) / (-6-(-2)) = (n+9 / (-4)

Now set this slope equal to -1 and solve the resulting equation for n:

(n+9) / (-4) = - 1, or   (n+9) / 4 = 1, or n+9 = 4.  Then n = -5.

Amelie needs 2| 3/8 cups flour for one recipe and 1| 1/3 cups of flour for another recipe.
ryzh [129]

Answer:

3 and 17/24 cups of flour

Step-by-step explanation:

You need to make the denominator the same so find what number the 8 and 3 can both be turned into to make the same number. They can both be made into a 24. 8x3=24 so you multiply the 3 by 3 making 9. Do the same to the 1/3, multiplying both by 8 making 8/24.

2 9/24 and 1 8/24 which can be made into 3 17/24
