Answer:
t<45 mins
Step-by-step explanation:
If to qualify you must finish in less than 45 minutes, this simply means your time has to be less than 45 so it would be t<45 mins. If it had said in 45 mins or less, it would say t is less than or equal to 45 but that's not what we have here.
Answer:
1. 18
2. 72
3. 90%
Step-by-step explanation:
For number 1
To find percentage you multiply the total number of kids with the percentage.
To do this you have to convert the percent into a decimal by moving the dot 2 times from its original location Ex. 20% = .20 as 20 would look like 20.00 in decimal form.
So .20 x 90 = 18
For number 2
Subtract 18 and 90 to find the remanding kids
For number 3
Divide 72 and 90. Make sure the lower number is being divided.
The answer you will get is .8 so move the decimal back two times because you are converting it to a percentage."
You will then get 80.00 as an answer then from there turn it to a percentage
80%
Hope this helps!
Answer:
26+13i
Step-by-step explanation:
(4+7i)(3−2i)
Multiply complex numbers 4+7i and 3−2i like you multiply binomials.
4×3+4×(−2i)+7i×3+7(−2)i^2
By definition, i^2 is −1.
4×3+4×(−2i)+7i×3+7(−2)(−1)
Do the multiplications.
12−8i+21i+14
Combine the real and imaginary parts.
12+14+(−8+21)i
Do the additions.
26+13i
Real part steps:
(4+7i)(3−2i)
Multiply complex numbers 4+7i and 3−2i like you multiply binomials.
Re(4×3+4×(−2i)+7i×3+7(−2)i^2)By definition, i^2 is −1.
Re(4×3+4×(−2i)+7i×3+7(−2)(−1))
Do the multiplications in 4×3+4×(−2i)+7i×3+7(−2)(−1).
Re(12−8i+21i+14)
Combine the real and imaginary parts in 12−8i+21i+14.
Re(12+14+(−8+21)i)
Do the additions in 12+14+(−8+21)i.
Re(26+13i)
The real part of 26+13i is 26.
26
If there are 20 red seeds in each bag, then there are 20*2=40 green seeds in each bag.
There are 40*5=200 green seeds in 5 bags.
