Answer:

7569.36

Step-by-step explanation:

Given that a quantity with an initial value of 7800 decays continuously at a rate of 0.1% per hour. What is the value of the quantity after 1.25 days, 

First convert 1.25 days to hours

1.25 × 24 = 30 hours

Using exponential equation

N = No ( 1 - R% )^t

Where N = new value of the quantity

No = initial value

R = rate

t = time

N = 7800 ( 1 - 0.001 )^30

N = 7800 ( 0.999 )^30

N = 7800 × 0.97043

N = 7569.36154

N = 7569.36 to the nearest hundredth.

Therefore, the value of the quantity after 1.25 days is 7569.36

Step-by-step explanation:

Here we want to study the magnetic force due to a magnet, we will see that the correct option is D, move.

Magnets create a magnetic field around them, such that any object inside that field is affected due to that field (you can think that the magnet is submerged in this magnetic field that is in the space around it).

The magnetic field affects other magnetized objects (such as magnets) repulsing or attracting them, depending on the polarization (opposite polarizations attract and equal polarizations repel)

With that in mind, the property of the magnetic force is that it can move another magnet without touching them, thus the correct option is D, move.

Answer:

  z + y = 52; z - y = 10; z = 31; y = 21; $9.85 total

Step-by-step explanation:

The variables are defined in the problem statement. The equations could be ...

  z + y = 52 . . . . . . total number of coins

  z - y = 10 . . . . . . . 10 more quarters than dimes

These equations can be solved by adding them together.

  (z +y) +(z -y) = (52) + (10)

  2z = 62 . . . . . . . simplify

  z = 31 . . . . . . . . . divide by 2

  31 -10 = y = 21 . . . . find the number of dimes

There are 31 quarters and 21 dimes.

The value of the coins is ...

  31($0.25) +21($0.10) = $7.75 +2.10 = $9.85

Answer:

84 inches

Step-by-step explanation:

12 inches are in 1 foot, so you take the number of feet (28) and multiply by the number of inches in a foot (12)

28×12=336 (inches)

then you take 336 and divide by 4 to get your 4 equal pieces.

336 divided by 4 = 84, 84 inches

Answer:  The value of ∠K is 56°.

Step-by-step explanation:

Given: A pair of triangles Δ EDC ~ Δ KGH

∠E = 56°  and ∠H = 34° .

Since corresponding angles of similar triangles are equal.

⇒∠E = ∠K               ...(i)

⇒∠D = ∠G

⇒∠C = ∠H

∠E = 56°    [Given]

⇒∠K =  56°    [From (i)]

Hence, the value of ∠K is 56°.

he would have to take 8 more shots.

Step-by-step explanation:

9saves divided by 12 shots = .75

if you keep adding a shot and a save each time, you get to 17saves divided by 20shots=.85.

Hope this helps!

The percentage can be determined by multiplying the fraction to 100. In order to raise his save percentage to 0.850 goalie has to make one additional save.

Given that,

The number of shots saved out of 12 = 9.

Save percentage = (number of saves  ÷ number of shots faced)

In the given case save percentage is as below,

= 9 ÷ 12

= 0.75

Suppose the number of saves to increase the save percentage to 0.85 be N.

Then as per the question,

0.85 = N ÷ 12

=> N = 12 × 0.85

=> N = 10

Thus, the number of additional saves is given by 10 - 9 = 1.

Hence, goalie must make one additional save to raise his percentage to 0.850.

Step-by-step explanation:

Answer:

4 pitches

Step-by-step explanation:

if a cylinder with height 9 inches and radius r is filled with water, it can fill a certain pitcher. how many of these pitchers can a cylinder with height 9 inches and radius 2r fill? explain how you know.

Solution:

The volume of a cylinder is given by:

V = πr²h;

where V is the volume, r is the radius of the cylinder and h is the height of the cylinder.

A cylinder with height 9 inches and radius r can fill a certain pitcher. Therefore the volume of the cylinder is:

V = πr²h = πr²(9) = 9πr²

V = volume of pitcher = volume of cylinder with radius r = 9πr²

For a cylinder with height 9 inches and radius 2r its volume is:

V2 = πr²h = π(2r)²(9) = 36πr²

Therefore, the number of pitchers a cylinder with height 9 inches and radius 2r can fill is:

number of pitches = 36πr² / 9πr² = 4

Therefore a cylinder with height 9 inches and radius 2r can fill 4 pitches.

As,

17.44 ÷ 8 = 2.8

Answer:

are u sure the question is completed?

Since there is a negative on the y term, we need to get rid of that and thus flip the sign at the same time. Getting.

-43>8/3y

Now we just need to divide 8/3 on both sides dividing 8/3 on left can also be written as *3/8

-43*3/8>y

Now flip this entire equation

y<-43*3/8

y<-129/8

If your teacher want you to calculate just divide the fraction, but I recommend not to if your teacher don't ask for it and just leave it this way.

Answer:

Step-by-step explanation:

They're never going to be the same because Bob's Gym starts at a higher number and also increases by a larger number

Answer:

-20 months lol

Step-by-step explanation:

so the first step to this is to create and equation for each

for guys gym the equation would be 5x+100 and for bob's gym the equation would be 8x+160

because we want them to equal each other we write the equation

5x+100=8x+160 and solve for x to see how many months it will take for the gyms to charge the same amount

step 1 subtract 100 from each side

5x=8x+60

step 2 subtract 8 from each side

-3x=60

step 3 divide each side by -3

x=-20 it will take -20 week for them to charge the same amount

Answer:

The equation for your graph is Y=2x+1

Answer:

Step-by-step explanation:

Given the expression 3 * 2 2/3

This can also be expressed as;

3 * 2 2/3

= 3 * 8/3

= (24/3)

= 8

hence the product of both numbers is 8

The equivalent value of the fraction is A = 8

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first fraction be represented as p

Let the second number be represented as q

Now , A = pq

when the value of p = 2 2/3

And , when the value of q = 3

On simplifying the equation , we get

A = ( 2 2/3 ) / ( 3 )

So , the left hand side of the equation is equated to the right hand side by the value of ( 2 2/3 ) / ( 3 )

A = ( 2 2/3 ) / ( 3 )

A = ( 8/3 ) / ( 3 )

On simplifying , we get

Multiply by 3 on the fraction , we get

A = ( 8 x 3 ) / 3

A = 8

Therefore , the value of A = 8

Hence , the fraction is A = 8

Step-by-step explanation: Calculator

After multiplication of pair of complex numbers, the results of product are respectively 45, 41, 73

The complex number is a combination of real number and imaginary number. The representation of complex number is like, a + bi.

where a is real part and b is imaginary part, the value of i is √-1.

i × i = -1

i⁴ = 1

Given that, pair of complex numbers

(6 +3i )×( 6 - 3i) =  6×6 -6×3i + 6×3i - (3i × -3i)

                         = 36 - 18i + 18i + (-3i × 3i)

                         =  36 + 9

                         =  45

(4-5i) × (4+5i)   =  4×4 + 4×5i - 4×5i - (5i × -5i)

                        = 16 - 20i + 20i + (-5i × 5i)

                        = 16+25

                        = 41

(-3+8i) × (-3-8i) = -3×-3 + (-3× -8i) - 3×8i + (8i × -8i)

                        = 9 +24i-24i +64
