how do i solve 2i x 3i
Answer:
it's 6
Step-by-step explanation:
2*3 is 6 and I*I is i^2 which equals to 1 so overall 6
Answer:
-6
Step-by-step explanation:
2i* 3i
Multiply the numbers 2*3 = 6
Multiply the imaginary number i*i = i^2
We know that i^2 = -1
6* i^2 = 6*-1 = -6

Catalin works in an office. One week he divides his time between these tasks:
1/4 of his time in meetings
5/8 of his time writing reports
the rest of his time doing the accounts
He spends a total of 6 hours doing the accounts
Find the total number of hours he works in the week. How would I go about solving this problem?
Answer:
Catalin works 48 hours during the week.
Step-by-step explanation:
Since Catalin divides his weekly worktime using 1/4 of his time in meetings, 5/8 of his time writing reports and the rest of his time doing the accounts, and he spends a total of 6 hours doing the accounts, to find the total number of hours he works in the week the following calculation must be performed:
1/4 + 5/8 = X
1/4 + 2.5 / 4 = X
3.5 / 4 = X
0.5 = 6
(4 / 0.5) x 6 = X
8 x 6 = X
48 = X
Therefore, Catalin works 48 hours during the week.

Gwendolyn placed a 10-foot ladder against the side of her house so that the base of the ladder was 3 feet from the base of the house, as shown in the diagram below. Which measurement in feet is closest to d, the distance from the top of the ladder to the ground?
Answer 9.5
you do the pyragtaham theory thing its A(squared) + B (squared) = C squared
you put the 3 at the A and you put the 10 at the C you sqaure them all up and then subtrct 9 from 100 and you get 91 and then you square root 91 and you get 9.5
The distance from the top of the ladder to the ground is 9.54 ft.
What is a right triangle?"It is a triangle whose one of the angle is 90°"
What is hypotenuse?"The longest side of the right triangle is called as hypotenuse."
What is Pythagoras theorem?"For a right triangle,
c² = a ² + b²,
where c = hypotenuse and a, b are other two sides of right triangle."
For given example,
Gwendolyn placed a ladder against the side of her house.
This means, it makes right triangle with ladder hypotenuse and base of the triangle is the distance between base of the ladder and the base of the house.
Let 'a' be the hypotenuse of triangle, 'b' be the base and 'd' be the distance from the top of the ladder to the ground
⇒ a = 3 ft. and b = 10 ft.
Using Pythagoras theorem,
⇒ b² = a² + d²
⇒ 10² = 3² + d²
⇒ 100 = 9 + d²
⇒ d² = 91
⇒ d = 9.54 ft.
Therefore, the distance from the top of the ladder to the ground is 9.54 ft.

Answer:
87.5%
Step-by-step explanation:
There are 376 students in 8th grade at Samuel's school. There are 47 8th graders trying out for football last Thursday.
The number is students not trying out for football last Thursday is calculated as:
376 students - 47 students
= 329 students
The percent of 8th graders that did not try out for football is calculated as:
329 students/376 students × 100
= 329/376 × 100
= 87.5 %

Josh can long-jump 195% of his height with a running start. If Josh is 66 inches tall, how far can he long-jump?
Answer: 128.7 inches
Step-by-step explanation:
Josh's height is 66 inches.
When he jumps with a running start, he can jump as far as 195% of his height.
The length he can jump is therefore 195% multiplied by his height:
= Josh height * 195%
= 66 * 195/100
= 128.7 inches
Answer: 128.7

The polygons are similar. Find the values of
the variables. Write an equation and solve,
showing ALL the work.
Answer:
x = 12, y = 8
Step-by-step explanation:
Since we know that the two triangles are similar that means we can find the ratio. The larger triangle is two times larger, we can find that out using 7/3.5 = 2. That means x + 4 = 2y and 3y = 2x. We can solve for y using substitution. We can double the first equation. 2x + 8 = 4y. We know that 2x = 3y so we can plug that in. 3y + 8 = 4y. Solving for y, gets us y = 8. Now we can plug that into any of the prior equations. I'll use 3y = 2x. 3(8) = 2x. 24 = 2x. Divide both sides by 2. x = 12.

The time required to complete a job varies inversely as the number of people working. It took 4 hours for 7 electricians to wire a building. How long would it have taken 3 electricians?
A. 1 hour 43 minutes
B. 5 hours 15 minutes
C. 7 hours 30 minutes
D. 9 hours and 20 minutes
Answer:
9 hours and 20 minutes: b
Step-by-step explanation:
4*60=240
7x240=1680
1680/3=560
560= 9 h 20 m
The time required when 3 electricians are working is 9 hours and 20 minutes.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The time required to complete the job varies inversely with the number of people working.
This means that if the number of people working decreases, the time required to complete the job will increase.
We can use the formula for inverse variation to solve the problem:
t = k/n
where t is the time required to complete the job, n is the number of people working, and k is a constant of proportionality.
We can find k by plugging in the given values:
4 = k/7
k = 28
Now we can use the formula to find the time required when 3 electricians are working:
t = 28/3
t ≈ 9.33 hours
Converting this to hours and minutes, we get:
t ≈ 9 hours and 20 minutes
Thus,
The time required when 3 electricians are working is 9 hours and 20 minutes.

Answer:
A. All motion is relative to the frame of reference chosen for measurement.
Step-by-step explanation:
Student 1 riding in the car is going at a certain speed. He sees the bus going a bit faster, so he thinks the bus is going at 20 km/h because to him, since he is also moving, it seems that the bus is only a little faster. Student 2 is on the sidewalk standing. He is not moving. When he sees the bus moving, the bus seems to be going fast because he is not moving. He estimates the speed of the bus to be 50 km/h.
The difference in estimates is due to their frames of reference.
Answer: A. All motion is relative to the frame of reference chosen for measurement.
