Mathematics
1 answer:
TiliK225 [7]3 years ago
3 0

Answer:

Q1: is 0

Q2: is 20

Step-by-step explanation:

Q1: Divide the numbers 0 ÷ 6 = 0

√8 × 0

√8 = 2√2

2 × 0 × √2

Apply rule 0 × a = 0

Q2: Apply exponent rule : (a × b)^n = a^n b^n

2^2(√5)^2 = 2^2 (√5)^2

2^2 = 4

4 (√5)2

(√5)^2 = 5

4 × 5

Multiply the numbers: 4 × 5 = 20

Solve please. 20 points.
Yakvenalex [24]

Answer:

336 cm^2

Step-by-step explanation:

Well theres not exactly a formula, I jsut solve the 3 faces and then double it all since 2 are the same for each except for 1 so the first side is the 10X12 one. that would give you 60 and then you double that and get 120 since 2 same faces.

The next one the 6X13  one is just a sideways rectangle, a=lw and that would be 78. Two faces same side double 78 and get 156.

Now the final side is the bottom which is jsut 10X6. a=lw and that would eqaul 60. No need to double since thats the only side that doesn’t have a duplicate. Add all your result up and you would get

336 cm^2

The graph shows the distances traveled by two toy trains.
liraira [26]

From the graph ...

-- Train-1  travels more than  15  feet in  3  seconds.

-- Train-2  travels less than  15  feet in  3  seconds.

So, if  Train-3  travels exactly  15  feet in  3  seconds,
then  Train-3  is faster than  #2  but slower than  #1 .

Here are the monthly charges for Jo's mobile phone
Sindrei [870]
Jo's Mobile Plan:
Fixed monthly charge = £16
Monthly 150 free minutes, post that 13p (or £0.13) per minute,
Monthly 150 free texts, post that 15p (or £0.15) per text
Jo's mobile phone usage details:
170 minutes of calls
182 texts
Total Charges for Jo = Fixed Monthly Charge + Charges for Calls + Charges for Texts
⇒ Total Charges for Jo = 16 + (170-150) × 0.13 + (182-150) × 0.15
⇒ Total Charges for Jo = 16 + (20) × 0.13 + (32) × 0.15
⇒ Total Charges for Jo = 16 + 2.6 + 4.8
⇒ Total Charges for Jo = 23.4
Hence, Jo should be charged £23.4 for the month.

Hope this helps !
