The following cone has a height of 12 cm and a slant height of 13 cm. A right angle is formed between the height and radius of t

Pachacha [2.7K]

Length of the radius of the cone is equals to 5 cm.

<h3>What is right circular cone?</h3>

" A right circular cone is the 3 dimensional solid shape, which has an axis that is perpendicular to its circular base."

Formula used

Pythagoras theorem

(Hypotenuse)² = (adjacent side)² + (opposite side)²

According to the question,

Slant height 'l' of the cone = 13cm

height 'h' of the cone = 12cm

Let 'r' be the radius of the base of the cone.

As per the diagram,

InΔABC,

Apply Pythagoras theorem, we get

(l)² = (h)² +(r)²

Substitute the values of 'l' and 'h' in the formula we get,

(13)² =(12)² + (r)²

⇒ (r)² = 169 - 144

⇒ r =√25

⇒ r = 5cm

Hence, length of the radius of the cone is equals to 5 cm.

A woman is q years old while her son is p years old. the sum of their ages is equal to twice the difference of their ages. the p

Allisa [31]

Step-by-step explanation:

Given

$q + p = 2(q - p)$

as equation 1.

I used q-p as the difference as logically the woman will be older than her son.

Also given,

$qp = 675$

as equation 2.

Using equation 2,

$q = \frac{675}{p}$

substitute this equation into equation 1.

$\frac{675}{p} + p = 2( \frac{675}{p} - p) \\ \frac{675}{p} + p = \frac{1350}{p} - 2p \\ \frac{675}{p} - \frac{1350}{p} = - 2p - p \\ - 3p = - \frac{675}{p} \\ - 3p \times p = - 675 \\ - 3 {p}^{2} = - 675 \\ {p}^{2} = - 675 \div - 3 \\ {p}^{2} = 225 \\ p = \sqrt{225} \\ = 15$

Substitute P into equation 2.

$15q = 675 \\ q = 675 \div 15 \\ = 45$

Therefore the woman is 45 years old while her son is 15 years old.

What is the decimal multiplier to decrease by 72%?

mixer [17]

Answer:

0.28

Step-by-step explanation:

Given in question that,we have to decrease by 72%.that means from 100% of total, 72% should be decreased. that means an overall of 28% will be left. so if you make a number into 28% of it, it implies that you have decreased that number by 72%.so from this,we can say that we have to make the number 28%.that means we have to multiply the number with 28/100 which is equal to 0.28.

Tommy has a history test on Monday morning. He writes down the number of minutes he studies for the test each day for a week. Us

Schach [20]

To find the average, add up all the numbers, then divide that answer by the quantity of numbers.

STEP 1:
add all numbers

=30 + 20 + 0 + 0 + 0 + 0 + 120
=170 total

STEP 2:
divide total from step 1 by 7 (total quantity of numbers given, including zeros)

=170 ÷ 7
=24.2857
=24.3 rounded to nearest tenth

***You could also calculate the average by adding only non-zero results (20,30,120) and then dividing by 3 (the quantity of only non-zero numbers).

ANSWER: The average number of minutes studied per day is 24.3.

Hope this helps! :)
