Which construction correctly shows how to construct a perpendicular bisector ok XY?
A). a
B). b
C). c
D). d

Answer:

pass the code

Step-by-step explanation:

Dale spends 12 hours on the internet, 75% on messages and 25% on games.

To make this easier, we can just convert the percentages into fractions and then continue.

To turn a percentage into a fraction, take the percentage number and put it into the numeriator, and add 100 to the denominator.

75% = 75/100  

25% = 25/100

Simplify!

75% = 75/100 = 3/4

25% = 25/100 = 1/4

So, now we know how to convert the percentages into a fraction. Now! We must use the fractions to find out how to find the time he uses to play games.

We know now that he spends 1/4 of his time working on games, and 3/4 of his 12 hours working on messages. However, we want to know how much 1/4 is. Divide 12 by the denominator, 4, and this will determine how long 1/4 is.

12 / 4 = 3  

So, that means that of his 12 hours he spends on the internet, he spends 3 hours doing games.

Now, subtract the time he spends doing the games by the time he spends on the internet to find the time on he spends messaging.

12 - 3 = 9

Which means that:

9 = Hours Spent Doing Messaging

3 = Hours Spent Playing Games

Answer:

8 more men are needed to complete the job

Step-by-step explanation:

Proportions

This problem can be solved by step-by-step reasoning applying proportions:

The above statement stands because the fewer hours of work, the more time the job needs to be completed. Let's continue.

The same reasoning applies here, fewer men=more days.

Now for the second condition. Increase the hours/day:

More hours/day=less days to complete the job

We know this last time is 12 days, thus:

[tex]\displaystyle 12=\frac{14*9*16}{7*x}[/tex]

Solving for x:

[tex]\displaystyle x=\frac{14*9*16}{7*12}=\frac{2016}{84}=24[/tex]

24 men are needed now, this is an increase of 24-16=8 more men

8 more men are needed to complete the job

Answer: 46-3i

Step-by-step explanation: Use the FOIL method, (a+b)(c+d)=ac+ad+bc+bd. Collect like terms then simplify.

(6+7i)(3−4i)

18−24i+21i+28

(18+28)+(−24i+21i)

46-3i

- Hope this helps, have a blessed and wonderful day! :-)

In the standard form we can write (6 + 7i)(3 − 4i) as (- 3i + 46).

A complex number is a number of the form a + bi, where [a] and [b] are real numbers and [i] is equal to [tex]\sqrt{-1}[/tex].

Given is the following complex expression -

(6+7i)(3−4i)

We have -

(6 + 7i)(3 − 4i)

On expanding, we get -

6(3 - 4i) + 7i(3 - 4i)

18 - 24i + 21i - 28i²

18 - 3i - 28i²

18 - 3i - 28 (-1)

18 - 3i + 28

46 - 3i

- 3i + 46

Therefore, in the standard form we can write (6 + 7i)(3 − 4i) as (- 3i + 46)

Step-by-step explanation:

Correction:

A trader sells 5 mobiles for Rs 35840 and had profit of 12% . Find the cost price of each mobile.

Solution:

Selling price of 5 mobiles = Rs 35840

Now, we have to find the selling price of 1 mobile. So, for the cost of 1 mobile , the cost of 5 mobiles is divided by 5.

i.e [tex]\frac{35840}{5} =[/tex] Rs [tex]7168[/tex]

We have,

Cost of 1 mobile = Rs 7168

Profit % = 12 %

Finding the cost price of each mobile :

[tex]\boxed{\sf{ CP = \frac{SP * 100}{100 + Profit percent}}}[/tex]

[tex]CP = \frac{7168 * 100}{100 + 12}[/tex]

[tex]CP = \frac{716800}{112}[/tex]

[tex]CP =[/tex] Rs [tex]6400[/tex]

Step-by-step explanation:

The number expression 5⁻¹⁵ rewritten using a positive exponent as -5¹⁵ option (A) -5¹⁵ is correct.

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that:

The number expression is:

= 5⁻¹⁵

By the property of the integer exponent we can write the above number exponent as follows:

= (5¹⁵)(-1)¹⁵

(-1)¹⁵ = -1   (because 15 is the odd number)

= -5¹⁵

Thus, the number expression 5⁻¹⁵ rewritten using a positive exponent as -5¹⁵ option (A) -5¹⁵ is correct.

If L || M. Then the value of the variable 'x' will be 17.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees.

The side of the rectangle is L and M. If L || M.

L = 8x + 20

It should be 3:1 since the number of apples comes first in the ratio.

Answer:

yes, because if you express it as 1:3 or 1/3 is the same thing

Step-by-step explanation:

You can solve this with kinematics or with energy.

Using kinematics, given:

v₀ = 600 m/s

v = 200 m/s

Δx = 0.05 m

Find: a

v² = v₀² + 2aΔx

(200 m/s)² = (600 m/s)² + 2a (0.05 m)

a = -3,200,000 m/s²

Given:

v₀ = 600 m/s

v = 0 m/s

a = -3,200,000 m/s²

Find: Δx

v² = v₀² + 2aΔx

(0 m/s)² = (600 m/s)² + 2(-3,200,000 m/s²) Δx

Δx = 0.05625 m

So the bullet needs to travel an additional 0.00625 m, or 0.625 cm.

Using energy, the work done on the bullet equals the change in kinetic energy.

ΔKE = W

½ mv² − ½ mv₀² = Fd

½ m (200 m/s)² − ½ m (600 m/s)² = F (0.05 m)

(-160,000 m²/s²) m = F (0.05 m)

F/m = -3,200,000 m/s²

½ mv² − ½ mv₀² = Fd

½ v² − ½ v₀² = (F/m) d

½ (0 m/s)² − ½ (600 m/s)² = (-3,200,000 m/s²) d

d = 0.05625 m
