1 answer:

Answer:

x = 20°

y = 70°

Step-by-step explanation:

the angle adjacent to the 40° angle must be 140° because the two angles form a straight line (which contains 180°)

in the isosceles triangle with the 'x', that means the other two angles must be equal and are (180-140) ÷ 2, which equals 20°

to find 'y', consider the larger right triangle with angles of 90° and 20°; angle y must equal 180 - (90 + 20) = 70°

Consider the formula P = \dfrac{ H\cdot d}{m}P=

Lilit [14]

Answer:

The productivity is measured in cubic meters per kilogram.

Step-by-step explanation:

For the formula for the productivity $P$ of the camel

$P = \dfrac{ H\cdot d}{m}$

where $H$ is the area of the hump and is measured in square meters, $d$ is the distance the camel can travel (measure in meters), and $m$ is the mass of the camel (measured in kilograms $kg$ ).

Then, the productivity of the camel is measure in

$P=\dfrac{meters^2\:*meters}{kilograms}$

$P=\dfrac{m^3}{kg}$

cubic meters per kilogram.

Does someone know the answer to 3/12=2/?

Elina [12.6K]

Answer:

2/8

Step-by-step explanation:

since 3/12 = 1/4, you have to find a fraction that equals 1/4 that has 2 as the numerator.

that would be 2/8 since 1/4=2/8.

The height of a triangle is 8ft greater than the base. The area of the triangle is 136.5 square ft. Find the length of the base

mixer [17]

Answer:

the base is 9/2 ft and the height is 9/2 + 8, or 25/8, ft.

Step-by-step explanation:

Note that the formula for the area of a triangle is A = (1/2)(base)(height). Let's abbreviate that to A = (1/2)(b)(h). We are told that h = b + 8.

Then A = 136.5 = (1/2)(b)(b + 8), or

(after multiplying both sides by 2)

A = 273 = b^2 + 8b

which, when put into standard quadratic form, becomes:

b^2 + 8b - 273 = 0

The coefficients of this quadratic are a = 1, b = 8 and c = -273.

Thus, the discriminant is b^2 - 4ac, or 64 - 4(1)(-273) = 1156 = 17^2.

The roots are then

-8 ± √1156 -8 ± 17

x = -------------------- = ------------ = 9/2 and -25/2

2 2

Only the root 9/2 makes sense here, because measurements of length are positive.

Thus, the base is 9/2 ft and the height is 9/2 + 8, or 25/8, ft.

A cone has a volume of 24 cubic inches. What is the volume of a cylinder that the cone fits exactly inside of?

Soloha48 [4]

Answer:

72 cubic inches

Step-by-step explanation:

Volume of cone = $\frac{1}{3}\pi r^{2} h$ --1

Volume of cylinder = $\pi r^{2} h$ --2

We are given that a cylinder should fit exactly inside the cone

On comparing 1 and 2 we can see:

$\text{Volume of cone}= \frac{1}{3} \text{Volume of cylinder}$

Since we are given the volume of cone is 24 cubic inches .

So, $24= \frac{1}{3} \text{Volume of cylinder}$

$24 \times 3= \text{Volume of cylinder}$

$72= \text{Volume of cylinder}$

Hence the volume of cylinder is 72 cubic inches

Option D is correct.
