first, you must make the fractions have the Least Common Denominator, which in this case is 4. the new equation is 24 1/4 - 15 2/4. then you just subtract. the answer is <u>8 3/4</u>

Austin keeps a right conical basin for the birds in his garden as represented in the diagram. The basin is 40 centimeters deep,

Alenkinab [10]

Answer:

51.15 cm

Step-by-step explanation:

Data provided

Basin = 40 centimeters deep

The Angle between the sloping sides = 77°

The calculation of the shortest distance between the tip of the cone and its rim is shown below:-

The angle will get divided and the angle is as follows

$\frac{77^\circ}{2}=38.5^\circ$

Here In the first triangle, we will follow "Cosine formula" which follows:-

$\cos 38.5^\circ=\frac{Base}{Hypotenuse}$

$cos 38.5^\circ=\frac{40}{Hypotenuse}$

$\\\\0.782=\frac{40}{Hypotenuse}$

$\\\\Hypotenuse=\frac{40}{0.782}$

$=51.15\ cm$

The value of x is?<br> 84<br> 96<br> 132<br> 264<br> HELPPPP!!!!

Alexandra [31]

The 3 outside angles of a triangle need to equal 360 degrees.

To find X, subtract the 2 outside angles shown from 360.

X = 360 - 130 - 134 = 96

The answer is 96

Solve 2(x – 11)2 = 128.

Andrew [12]

Answer:

Step-by-step explanation:

Multiply the numbers 2 ( x - 11 ) * 2 = 128

4 ( x - 11 ) = 128

Distribute 4 ( x - 11 ) = 128

4x - 44 = 128

Add 44 to both sides 4x - 44 = 128

4x - 44 + 44 = 128 + 44

Simplify - Add the numbers

4x - 44 + 44 = 128 + 44

4x = 128 + 44

- Add the numbers

4x = 128 + 44

4x = 172

Divide both sides by the same factor 4x = 172

4x/4 = 172/4

Simplify

- Cancel terms that are in both the numerator and denominator

4x/4 = 172/4

x = 172/4

-Divide the numbers

x = 172/4

x = 43
