Answer: a) 30 and b) 24.

Step-by-step explanation:

Since we have given that

a) Number of visitors = 100

According to question, we get that If three-tenths of the visitors were adults.

So, number of adults would be

\dfrac{3}{10}\times 100\\\\=3\times 10\\\\=30

b) Number of prizes = 64

According to question, Five-eighths of the prizes at the Giant Spin were dolls.

So, Number of prizes are not dolls is given by

(1-\dfrac{5}{8})\times 64\\\\=\dfrac{3}{8}\times 64\\\\=3\times 8\\\\=24

Hence, a) 30 and b) 24.

Find all numbers whose absolute value is – 3.
Gwar [14]

Answer:

remember that |x|=x if x\geq0 and |x|=-x \; \text{ if } x\leq 0. This means that |x| always is a positive number.

Then, there are no numbers such that |x|=-3 because -3 is a negative number.

Need help with this question; What is the measure of one leg of a right angle given that the hypotenuse measure 14cm and the oth
melamori03 [73]

Answer:

11.5 cm

Step-by-step explanation:

The dimensions of a right angled triangle can be determined using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c = hypotenuse

a² + 8² = 14²

a² + 64 = 196

a² = 196 - 64

a² = 132

find the square root of 132

a = 11.5 cm
