Find the volume of the square pyramid, given its slant height

Reptile [31]

Answer:

Step-by-step explanation:

base length b = 32 cm

slant height L = 30 cm

height h = √(L²-(½b)²)

= √(30²-0.25·32²)

≅ 25.3771550809 cm

volume V = (⅓)b²h

= (⅓)32²·25.38

≅ 8662.07 cm³

The arch of a bridge forms the upper half of an ellipse. The arch is 6 meters above the 20-meter-wide river. Write an equation f

aksik [14]

Answer:

$\frac{x^2}{36} + \frac{y^2}{100} = 1$

Step-by-step explanation:

Required

The equation of the ellipse

This is calculated as:

$\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1$

Where:

$b =6$ ---- height

$a = 0.5 * 20 =10$ --- width

So:

$\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1$

$\frac{x^2}{6^2} + \frac{y^2}{10^2} = 1$

$\frac{x^2}{36} + \frac{y^2}{100} = 1$

A middle school is selling tickets to a play. The number of child tickets sold is half the number of adult tickets sold. They so

Sidana [21]

Answer:

child tickets - 47

adult tickets - 94

Explanation:

since the number of adult tickets sold is twice that of the number of child tickets sold, we can divide 141 into three parts to find the number of child tickets sold.

141 ÷ 3 = <u>47</u> (number of child tickets sold)

we can now multiply this by two to find the number of adult tickets sold.

47 × 2 = <u>94</u>

i hope this helps! :D
