In a cash drawer there is $125 in $5 and $10 bills. The number of $10 bills is twice the number of $5 bills. How many of each ty
WINSTONCH [101]

Let us take number of $5 bills = x and

                   number of $10 bills  = y.

Give that "number of $10 bills is twice the number of $5 bills".

So, y is twice of x,

We can setup an equation.

y= 2x                      ............................... equation(1)

Total value of all bills = $125.

We can setup another equation,

5*(number of $5 bills) + 10*(number of $10 bills) =125.

5(x) +10(y) = 125                         ................................... equation(2)

Plugging y=2x in equation(2), we get

5(x) +10(2x) = 125   .

5x+20x = 125.

Adding like terms

25x = 125

Dividing both sides by 25.

25x /25 = 125/25

x= 5.

Plugging x=5 in first equation, we get

y= 2(5) = 10.

Therefore, number of number of $5 bills=5 bills  and number of $10 bills = 10 bills.

PLATO: Type the correct answer in each box. The vector is first dilated by a factor of 2.5 and then rotated by pi/2 radians. If
yawa3891 [41]

Answer:

a = -1, b = -2.5

Step-by-step explanation:

Rule for the dilation of a vector \binom{x}{y} by a scale factor of k is,

(x, y) → (kx, ky)

BY using this rule for a vector \binom{-1}{4} by a scale factor of 2.5

\binom{-1}{4} → \binom{-2.5}{1}

Followed by the rotation by 90° Or \frac{\pi }{2} radians,

Rule for rotation of a vector by 90° is,

(x, y) → (-y, x)

By this rule vector \binom{-2.5}{1} will become,

\binom{-2.5}{1} → \binom{-1}{-2.5}

If we represent this vector by \binom{a}{b},

Then a = -1 and b = -2.5 will be the answer.

The point (–3, –5) is on the graph of a function. Which equation must be true regarding the function?
Artist 52 [7]

Answer:

f(-3)=-5

Step-by-step explanation:

we are given a point as

(-3,-5)

we know that any point can be represented as (x,y)

so, (x,y)=(-3,-5)

now, we can find x and y

we get

x=-3

y=-5

we know that any function can be represented as

y=f(x)

It means when x=-3 , y=-5

so, we can plug these values

and we get

-5=f(-3)

f(-3)=-5
