Answer:

Step-by-step explanation:

a). By applying Pythagoras theorem in right triangle ABC,

AC² = AB² + BC²

20² = 16² + BC²

BC = $\sqrt{400-256}$

= 12

Therefore, another leg of the triangular base = 12 cm

Area of the triangular base ABC = $\frac{1}{2}(\text{Base})(\text{Height})$

= $\frac{1}{2}(16)(12)$

= 96 cm²

Volume of a triangular prism = Area of the triangular base × height

960 = 96 × b

b = 10 cm

b). Area of the triangle ABC = 96 cm²

At a pressure 41 kPa, the gas in a cylinder has a volume of 16 liters. Assuming temperature remains the same, if the volume of t

DiKsa [7]

If temperature (T) and amount of gas (n) remain constant, but pressure (P) and volume (V) change, then the ideal gas law: PV = nRT becomes
P1V1 = P2V2 --> (41)(16) = P2 (4)
--> P2 (4) = 656
P2 = 656/4 = 164 kPa

Ifn || m, find the value of x and the value of y.

Marat540 [252]

Answer: Option C

$y=5$ , $x=10$

Step-by-step explanation:

If the lines m and n are parallel then the large triangle and the small triangle are similar triangles, because they have equal angles.

By definition for similar triangles it is satisfied that if they have sides of length a, b, c and a', b', c' then:

$\frac{a}{a'}=\frac{b}{b'} =\frac{c}{c'}$

In this case

$a = 12\\a' = 4\\c = 15\\c' = y$

So:

$\frac{12}{4}=\frac{15}{y}$

Now solve the equation for the variable y

$3=\frac{15}{y}$

$y=\frac{15}{3}$

$y=5$

We know that

$x+y=15$ and $y=5$

Then

$x+5=15$

$x=10$

Finally the answer is:

$y=5$ , $x=10$

What does x equal in this equation -6=3/4x

SOVA2 [1]

Answer:

x = -1/8

Step-by-step explanation:

to determine the value of x in the expression-6=3/4x

first, cross multiply inorder to have a straight line equation ,then combine the like terms together and evaluate.

solution

-6=3/4x

using cross multiplication techique

4x × -6 = 3

-24x = 3

divide both sides by the coefficient of x which is -24

-24x/-24 = 3 /-24

x = -1/8

Multiply and simplify

steposvetlana [31]

That would be the cube root of (x+5)^11.

If desired, this could be reduced to the cube root of (x+5)^9*(x+5)^2, which would be

(x+5)^3*(x+5)^(2/3)
