Jonathon has a collection of coins worth a total of $10.75. If he has one-fourth as many dimes as pennies, and two-thirds as man
Mrrafil [7]

Step-by-step explanation:

d = number of dimes

n = number of nickels

p = number of pennies

d×$0.10 + n×$0.05 + p×$0.01 = $10.75

d = p/4

d = n × 2/3

now we need to transform these equation and substitute the variable equations in the main equation, so that we have actually only one variable left. and that we can solve.

so, it seems to me transforming p and n into expressions of d might be the easiest one.

d = p/4

=>

p = 4d

d = n × 2/3

=>

3d = 2n

n = d × 3/2

so, now putting that into the main equation

d×$0.10 + (d × 3/2)×$0.05 + 4d×$0.01 = $10.75

since we have a fraction in there, let's multiply everything by that denominator (2) to be fraction free :

2d×$0.10 + 3d×$0.05 + 8d×$0.01 = $21.50

now we can simplify the terms by multiplying the integer factors of d into the value decimals

d×0.20 + d×0.15 + d×0.08 = 21.50

now we can simply add up ask the factors of d

d×(0.2 + 0.15 + 0.08) = 21.50

d×0.43 = 21.50

d = 21.5 / 0.43 = 50

p = 4d = 4×50 = 200

n = d × 3/2 = 50 × 3/2 = 25 × 3 = 75

so he has 50 dimes, 75 nickels and 200 pennies

Smiley's Cookies makes the best chocolate chip cookies in town! Yesterday, the store sold 7 large cookies for every 5 small cook
True [87]

Answer: The number of small cookies sold = 75

Step-by-step explanation:

GIven: Yesterday, the store sold 7 large cookies for every 5 small cookies.

Let 7x be the number of cookies and 5x be the number of small cookies.  (i)

They sold 30 more large cookies than small cookies.

i.e. 7x-5x=30           (Using (i))

\Rightarrow\ 2x=30\\\\\Rightarrow\ x=\dfrac{30}{2}\\\\\Rightarrow\ x=15

Thus, the number of small cookies sold = 5 (15)=75   (Using (i))

Hence, the number of small cookies sold = 75

The equation of a circle is ​ (x−2)^2+(y−16)^2=169 ​ . What is the circle's radius?
Svetllana [295]
Hello!

The equation for a circle is

(x-h)^{2} +(y-k)^{2} =  r^{2}

r is the radius

To find the radius we take the square root of the number in the radius spot

sqrt169 = 13

The answer is 13

Hope this helps!
