Amir has a bag of dimes and quarters. He has a total of 31 coins worth $5.20.

Step2247 [10]

Answer

B is the correct answer.

Step-by-step explanation:

This is the given information for which system of equations would be used to find out how many dimes and quarters Amir has?

x = dimes x = 0.10 or 0.1

y = quarters y = 0.25

31 coins

worth $5.20 = 5.2

x + y = 31

0.1x + 0.25y = 5.2

You and your friend collect each rocks and fossils. your friend collects three times as many rocks and half as many fossils as y

Murljashka [212]

Answer:

you - 4 rocks and 16 fossils
friend - 12 rocks and 8 fossils

Step-by-step explanation:

Let the rock be r and the fossil be f

Equations

You: r + f = 20
Friend: 3r + 1/2f = 20

Double the second equation and subtract the first one:

2(3r + 1/2f) - (r - f) = 2*20 - 20
6r - r = 20
5r = 20
r = 4

Then find f:

f = 20 - 4 = 16

So you collect 4 rocks and 16 fossils

Friend collects:

4*3 = 12 rocks and
1/2*16 = 8 fossils

ving as a relation, state the domain and range, then determine if it is a6.2X-2 0.-2Relation:DomainRangeFunction3 i

Travka [436]

The relation is the set of ordered pairs of point drawn in the graph

The points are:

(-2, 3), (0, 1), (2, -1), (3, -2)

So the relation is:

R = {(-2, 3), (0, 1), (2, -1), (3, -2)}

The domain is the values of x in the ordered pairs

x = -2, 0, 2, 3

The domain = {-2, 0, 2, 3}

The range is the values of y in the ordered pairs

y = 3, 1, -1, -2

Arrange them in the set

The range = {-2, -1, 1, 3}

A Ferris wheel has a diameter of 100 feet. The highest point of the wheel is 125 feet. The y-axis represents the center of the w

Free_Kalibri [48]

Answer: $x^2+(y-125)^2=2500$

Step-by-step explanation:

Given: The diameter of the Ferris wheel= 100 feet

therefore, the radius of the Ferris wheel= 50 feet

Also, the highest point of the wheel is 125 feet.

Since , y axis represents the center of the wheel.

The center of the wheel= (0,125)

The equation of circle with center (h,k) and radius 'r' is given by :

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

Thus, the equation of the circle with center (0,125) and radius=50 is given by :-

$(x-0)^2+(y-125)^2=(50)^2\\\Rightarrow\ x^2+(y-125)^2=2500$
