A) 1/7, 3/7, 9/7, 27/7, 81/7
Multiple the numerator by 3
B) 24, 12, 6, 3, 1.5
Divide by 2
Answer:
42 miles
Step-by-step explanation:
10% of 120 is 12 and 5% is 6 so first you need o multiply 10x3 to get 30% then 12x3 to get the miles. Then you add the six to 12x3 and the five to 10x3 and you get
35%=42
If a/b and c/d are proportional then (a/b)(d/c)=1, aka ad=bc
25/45=15/27?
25*27=45*15?
675=675?
true
they are proportional
Answer:
1/2 of 4/5 = 1/2 of four fifths = two fifths
Step-by-step explanation:
1/2 x 4/5 = 4/10
4/10 simplified is 2/5
4 divided by 2 = 2
---- ----
10 divided by 2= 5
Answer:
The length of the hypotenuse ≈ 39.7 cm
Explanation:
Since the given triangle is a right-angled triangle, this means that we can apply the Pythagorean theorem.
The equation for Pythagorean calculation is:
(hypotenuse)² = (first leg)² + (second leg)²
In the given, we have:
first leg = 30 cm
second leg = 26 cm
Substitute with the givens in the above equation to get the hypotenuse as follows:
(hypotenuse)² = (30)² + (26)²
(hypotenuse)² = 1576
This means that:
either hypotenuse = √1576 = 39.69 ≈ 39.7 cm ..........> accepted
or hypotenuse = -√1576 = -39.69 ......> rejected as length can't be negative
Hope this helps :)
