The length of DE=sqrt((1-4)^2+(4-0)^2)=sqrt(3^2+4^2)=5
In principle, a rhombus has four equal sides, so the perimeter is 4*5=20 (units)
However, to ensure there is no typo, it is advisable to calculate separately the length of each and every side.
Answer:
59%
Step-by-step explanation:
19/32= 59.375 so rounded would be 59 :)
Answer:
1 2/7
Step-by-step explanation:
Hi! so this is very easy to solve. Let me guide you through it!
6/7 divided by 2/3
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
6/7 X 3/2
For fraction multiplication, multiply the numerators and then multiply the denominators to get
6 x 3 18
__ ___ = ____
7 x2 24
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 18 and 14 using
GCF(18,14) = 2
18 ÷ 2 9
___ ___ = ___
14 ÷ 2 7
The fraction
9/7
is the same as
9÷7
Convert to a mixed number using
long division for 9 ÷ 7 = 1R2, so
9/7=1 2/7
so there fore =
6/7÷2/3=1 2/7
(sorrry this took long i was solving it!)
Answer: 286 minutes
Step-by-step explanation:
x : # of months that has gone by
0.24x : cost of the 24 cent plan after "x" minutes
39.95 + 0.10x : cost of the 10 cent plan after "x" minutes
1. 39.95 + 0.10x > 0.24x
2. 39.95 > 0.24x - 0.10x
3. 39.95 > 0.14x
4. 285.36 > x
x must be AT LEAST 286 minutes for plan #2 (39.95 + 0.10x) to be a better deal
Answer:
352 cm/s
Step-by-step explanation:
circ = 44pi
speed = distance * time
distance = circ * 4 = 176pi
speed = 176pi/0.5
