Answer:
B. 3,4 VoltStep-by-step explanation:
Here we need to use Ohm's Law, because we have electric current, voltage and resistances. This law state: [tex]V=IR[/tex]
So, first we need to calculate the total resistance to then find the voltage. The resistances can be placed in two ways: in parallel, in series.
The pair 4 and 8 ohms are parallel, so we solve:
[tex]R_{T}=\frac{1}{R_{1}}+\frac{1}{R_{2}}[/tex]
[tex]\frac{1}{R_{T}}=\frac{1}{4}+\frac{1}{8}=\frac{8+4}{32}=\frac{12}{32}=\frac{3}{8}[/tex]
Which is, [tex]R_{T}=frac{8}{3}[/tex]
Now, this total resistance of parallels ones is placed in series with the 3 ohm resistance, in this case we just sum, because they are in series:
[tex]R=3+\frac{8}{3}=\frac{9+8}{3}=\frac{17}{3}=5.67 ohm[/tex]
Now that we have the total resistance of the circuit, we use the Ohm's Law:
[tex]V=IR\\V=(0.6A)(5.67ohm)=3.4 Volt[/tex]
Therefore, the right answer is B.

Answer:
1. m∠B=110°
2. 560 cm3
3. Numerical data
4. 2000 cm3
5. 50%
Step-by-step explanation:
1. The explanation of part 1 is given in the attachment.
2. Given dimensions : 10 cm, 8 cm, and 7 cm.
Let Length of cuboid =10 cm
breadth/width of cuboid =8 cm
height of cuboid = 7cm
Volume of cuboid = length *width* height
=( 10 *8*7) cm3
=(560) cm3
3. Age, Birth date and weight are the types/examples of "Numerical Data" because these all are describe in terms of numeric values.
4. 1 liter = 1000 cm3 or 1 cm3 = 0.001 liter
1.5 liters =(1.5*1000) cm3 = (15*100) =1500 cm3
1 dm3 =1000 cm3
0.35 dm3 = (0.35*1000) cm3 = (35*10) cm3 =350 cm3
Given expression: 1.5 litre + 0.35 dm3 + 150 cm3 = cm3
1500 cm3 + 350 cm3 +150 cm3 = 2000 cm3

The rate that The price increased from the original price to today
Answers
Answer:
700%
Step-by-step explanation:
The price increased from $0.30 to $2.40. What is the rate of increase, in percentage?
We can use the formula shown below:
[tex]\frac{New-Old}{Old}*100[/tex]
Where
New Price is 2.40 and the Old Price is 0.30
We substitute and calculate:
[tex]\frac{New-Old}{Old}*100\\\frac{2.40-0.30}{0.30}*100\\=7*100\\=700[/tex]
Hence,
Price increased 700%

find the 30th term of the arithmetic sequence with a first term of 4 and a comman difference of 8
Answers
Answer:
236
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 4 and d = 8, thus
[tex]a_{30}[/tex] = 4 + (29 × 8) = 4 + 232 = 236
Question 2) An online gaming club has a one-time registration fee of $14.95 and charges $0.69 to buy each game. If Sammy has $60.00

66
°C 108
D

PLEASE HELP
Answers
Answer:
the answer is b beacause
Step-by-step explanation:
when you multiply 14.95 times 6 it equals b
Answer: 65
Step-by-step explanation:
Let the number of games be x, this means that the cost of x games will be 0.69x.
There is also a one-time registration fee of $14.95 , this means that for Sammy to register and buy game with $60 , the equation will be
14.95 + 0.69x =60
subtract 14.95 from both sides
0.69x = 60 - 14.95
0.69x = 45.05
divide through by 0.69
x = 45.05/0.69
x = 65.28985507
Therefore , the maximum number of games she can buy is 65
4²+2²-(-3²)=m²-(-1²)+(√3)²
Answers
Answer:
m = ± 5
Step-by-step explanation:
Given
4² + 2² - (- 3²) = m² - (- 1²) + ([tex]\sqrt{3}[/tex])² ← evaluate exponents
noting that - 3² = - 9 and - 1² = - 1
16 + 4 - (- 9) = m² - (- 1) + 3, that is
20 + 9 = m² + 1 + 3
29 = m² + 4 ( subtract 4 from both sides )
25 = m² ( take the square root of both sides )
m = ± 5
