An electrician needs to know that the relationship between amps, volts, and resistance is
expressed in the formula V = IR where V is volts, I is amps, and R is ohms. How large a
resistance is needed to produce 8 amps from 184 volts?
Answer:
R = 23 ohms
Step-by-step explanation:
Start with V = I*R. Solve for R: R = V/I
Here I = 8 amps and V = 184 volts, and so
R = (184 volts) / (8 amps) = 23 ohms

What is the approximate area?
Answer:
71.77cm
Step-by-step explanation:
Answer:
71.76 cm^2
Step-by-step explanation:
The composite figure is made up of a rectangle with a missing half circle and a triangle.
area = area of rectangle + area of triangle - area of half circle
For the circle, radius = r = diameter/2 = 7 cm/2 = 3.5 cm.
area = LW + bh/2 - (pi)r^2/2
area = 10 cm * 7 cm + 7 cm * 6 cm/2 + (3.14)(3.5 cm)^2/2
area = 70 cm^2 + 21 cm^2 - 19.24 cm^2
area = 71.77 cm^2
Answer: 71.76 cm^2

Answer:
(x,y) = (-2,7)
Step-by-step explanation:
7x+2y=0
9x+4y=10
y = -9x/4 + 5/2
7x+2 (-9x/4 + 5/2) = 0
5x/2 = -5
5x = -10
x = -2
use x and substitute to get y
y = -(9/4) (-2) +5/2 = 7
Use the distributive property to expand (simplify): 3(4x - 12yz)
Answer:
12x -36yz
Step-by-step explanation:
hope this helps!
Hello!
In order to simplify this expression, all we have to do is multiply 3 times the terms inside the parentheses:
3(4x-12yz)
12x-36yz
That's the final answer, because there are no like terms here, so we cannot simplify this expression any further.
Hope everything is clear.
Let me know if you have any questions!

daniel eats 2/10 of yogurt for breakfast each morning how much yogurt does daniel eats for 3 days
Answer:
6/10
Step-by-step explanation:
2/10 times 3/1=6/10
hope this helps:) plz mark me brainliest
Answer:
3/5
Step-by-step explanation:
alrighty, so this is a standard rate and multiplication problem. How do we know? Well, because there's a steady rate of 2/10 per day, and for 3 days so:
2/10 x 3 = 6/10
6/10 can be simplified:
6/10 ÷ 2 = 3/5
So Daniel eats 3/5 yogurt over the course of 3 days
hope this helps:)

The Snyder family uses up a 1 2 -gallon jug of milk every 3 days. At what rate do they drink milk?
Answer: 4 gallons per day
Step-by-step explanation:
From the question, we are informed that the Snyder family uses up a 12 -gallon jug of milk every 3 days.
The rate at which they drink milk will be gotten by dividing the gallons of milk they drink by the number of days. This will be:
= 12/3
= 4 gallons per day
Therefore, the rate they use in taking milk is 4 gallons per day.
Isabella invested $1300 in an account that pays 4.5% compounded annually. Assuming no deposits or withdrawals are made , find how much money Isabella would have in the account 14 years after her initial investment . Round to the nearest tenth.
Answer:
$2,407.5
Step-by-step explanation:
To solve this question, we will use the formula for calculating the amount formula as shown;
A =P(1+r)^n
Given that;
P = #$1300
r = 4.5% = 0.045
t = 14years
Substitute
A = 1300(1+0.045)^14
A = 1300(1.045)^14
A = 1300(1.8519)
A = 2,407.5
Hence Isabella would have $2,407.5 in her account after 14years
A truck requires 35 liters of petrol to travel a distance of
450km.Find
The amount that the truck owner has to pay to travel distance of
1050 km if a liter of petrol costs $2.95.
Answer:
$240.92
Step-by-step explanation:
From the question,
The distance traveled by the truck is directly proportional to the amount of petrol used.
I.e,
d ∝ v............... Equation 1
d = kv
d/v = k
d₁/v₁ = d₂/v₂............. Equation 2
Where d₁ and d₂ are initial and final distance respectively, v₁ and v₂ are initial and final amount of petrol used respectively.
Given: d₁ = 450 km, d₂ = 1050 km, v₁ = 35 liters
Substitute into equation 2 and solve for v₂
450/35 = 1050/v₂
v₂ = (1050×35)/450
v₂ = 36750/450
v₂ = 81.67 Liters.
If a liter of petrol cost $2.95,
Then,
81.67 liters will cost (81.67×$2.95) = $240.92
Find the volume of the figure.
Answer:
90 m³Step-by-step explanation:
Volume of the prism is the product of the base area and the height
Base area is:
A = 1/2*10*3.6 = 18 m²Volume is:
V = 18*5 = 90 m³Answer:
Required Answer :-The base is representing a trapezium.
So,
Area = ½ × 10 × 3.6
Area = 5 × 3.6
Area = 18 m²
Now,
Volume = 5 × Area
Volume = 5 × 18
Volume = 90 m²

If a house is built on sand is sinking at a rate of two inches per day which is the change in the height above ground of the house after 11 days
Answer:
Height of the house will reduce by 22 feet after 11 days.
Step-by-step explanation:
A house is sinking at the rate of 2 inches per day.
That means rate of sinking of the house is 2 inches in a day.
Therefore, house will sink or change in height of the house in 11 days
= Rate o change in height × Number of days
= 2 × 11
= 22 feet
Height of the house will reduce by 22 feet after 11 days.
