Robert has x books. Marie has twice as many books as Robert has. Together they have 18 books. Which of the following equations can be used to find the number of books that Robert has?Choose one multiple choice answer
x+x+2=18
x+2x=18
2x=18
Answer:
2x=18
Step-by-step explanation:
2 times 9 equals 18 and if they both have 18 together the only anwser would be 2x=18 x=9 Another way I could put it to make it more simple is 2X9=18 or 29=18

11. Angela is using several cones to decorate for a party. The cones she has
chosen are 8 inches tall and have a radius of 3 inches. What is the volume of
one of the cones to the nearest whole cubic inch?
Answer:
[tex]75.4 in^3[/tex]
Step-by-step explanation:
First start with your cone volume equation which is
[tex]V=\pi r^2\frac{h}{3}[/tex]
Now plug in what you know
r=3
h=8
[tex]V=\pi (3)^2(\frac{8}{3})[/tex]
put in calculator and get
[tex]75.4 in^3[/tex]

Given 300mL of a gas at 17.0 degrees Celsius, what is the volume at 10 degrees Celsius if the pressure remains constant?
Answer:
292.75mL
Step-by-step explanation:
From the ideal gas equation
PV= nRT
With each symbols having standard meaning
For pressure remaining constant the equation for two states can be written as
[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]
Given V_1 = 300mL, T_1 = 17° C = 290K and T_2 = 10°C or 283K
Now plugging values in above equation to find V_2
[tex]\frac{300}{290} =\frac{V_2}{283}\\V_2 =\frac{300}{290}\times283 = 292.75mL[/tex]
Therefore, the volume at 10 degrees Celsius = 292.75mL

A town government is designing a new bus system. The planners are deciding where to put the different bus stops. They want to pick a set of bus stop locations that will minimize the distance anyone needs to walk in order to get to any bus stop in town. What term best defines this kind of problem
Answer:
Optimisation Problem
Explanation:
Optimisation Problem is a mathematical economics, computer science problem - which finds the best solution from all feasible solutions (based on constraints & other aspects).
The problem might be in form of maximisation or minimisation. The bus system designing is based on minimizing walking distance. Thus is an optimisation problem.

The area of a circle is 201 square meters. Find
the radius.
Answer:
8.0meters
Step-by-step explanation:
Given data
Area of cirlce= 201 square meters
The expression for the area is
A=πr^2
Substitute our area
201= 3.14*r^2
r^2= 201/3.14
r^2= 64.01
square both sides
r= √64.01
r= 8.0 meters
Hence the radius is 8.0meters

Sum of interior angles of a quadrilateral is 360°
110° + 130° + x + x - 3° = 360°2x = 360° - 237°2x = 123°x = 61.5°(18)
Sum of interior angles of a hexagon is 180°*(6 - 2) = 720°
2*90° + 2x + 2(x + 22°) = 720°90° + x + x + 22° = 360°2x = 360° - 112°2x = 248°x = 124°(19)
Interior angles of a given pentagon are all marked as congruent, so the exterior angles are congruent too.
Sum of exterior angles is 360°.
x = 360°/5x = 72°

Eric and pam are paid $48.75 for their work. Eric worked 2.5 hours, and pam worked 4 hours. They split the money according to the amount of time each of them worked. How much is erics's share of the money? Explain.
Answer:
$18.75
Step-by-step explanation:
Determine the total hours worked by both individuals = 2.5 + 4 = 6.5 hours
Determine the fraction of hours that Eric worked = 2.5/6.5 = 0.384615
Multiply this fraction by the total amount earned = 0.384615 x $48.75 = $18.75

Alaina has 7 in her bank account and earns 6 each day . joel has 48 in his banck account and earn 8 earch day in how many days will joel have as much money alaina
Answer:
I think you wrote something wrong.
Step-by-step explanation:
If Alaina has $7 in her bank account and Joel had $48 in his Joel already has more then Alaina but I will attempt to teach you how to solve these types of problems.
for this example I'm giving Alaina 79 dollars.
First we know were starting with 79 dollars and increasing 6 dollars each day so the equation for this is; y = 6x + 79 that is Alaina's equation.
For Joel our equation will be; y = 8x + 48.
Since they already have 79 and 48 dollars in their bank we put those as our B in the equation cause they are our y-intercepts. (Y = mx + b) Next we know their increasing by 6 and 8 dollars a day so we make those our m. Once we have these equations we can plot them and see where the lines meet. (thats our answer) I plotted them on desmos graphing calculator.
They crossed at (15.5, 172) Which means it will take 16 days for Joel to catch up they will both have 172 dollars in the bank account on the 16th day.
Hope this helps!
