Pythagoras theorem ! (a²+b²=c²)
Q1) AC = √4.8²+3.6²
= √36
= 6cm
Q2) AB= √17.55² - 6.75²
= √262.44
= 16.2cm
Q3) BC= √14² - 6²
= √160
= 12.64911
= 12.6 cm (to 3sf)
Answer:
(a) greater
Step-by-step explanation:
When comparing numbers, it is helpful to have them in the same form. You could express them both as fractions with the same denominator, as percentages, as decimals, or any other form you like.
walk to school: 18%
close to school: 11/50 = 22/100 = 22% . . . (greater than 18%)
The portion of students who live within 1/2 mile of school is greater than the portion who walk to school.
_____
<em>Additional comment</em>
The % symbol essentially means /100.
Then 18% = 18/100 = 9/50. The fraction 11/50 is greater than this.
All you have to do is simplify each term. And by doing so, you will get 4y^-4 + 2 - 1
Answer:
B. 80 cm^2
Step-by-step explanation:
A = bh/2
A = (FE)(16 cm)/2
A = (10 cm)(16 cm)/2
A = 80 cm^2
