Complete question :
Trevor plans on buying a car. Four banks offer the annual interest rates shown.
Which list shows these interest rates in order from greatest to least
3 1/10%, 3 2/5%, 3 1/4%, 3 1/3%
Answer:
3 2/5% ; 3 1/3% ; 3 1/4% ; 3 1/10%
Step-by-step explanation:
Arrange the given interest rates in order ; greatest to least :
To make comparison easier, we can convert the fractional values to decimal ;
3 1/10%, 3 2/5%, 3 1/4%, 3 1/3%
3 1/10% = 3 + (1/10 = 0.1) = 3 + 0.1 = 3.1%
3 2/5%, = 3 + (2/5 = 0.4) = 3 + 0.4 = 3.4%
3 1/4%, = 3 + (1/4 = 0.25) = 3 + 0.25 = 3.25%
3 1/3% = 3 + (1/3 = 0.333) = 3 + 0.333 = 3.33%
Hence, arranging in descending order (greatest to least) :
3 2/5% > 3 1/3% > 3 1/4% > 3 1/10%
3 2/5% ; 3 1/3% ; 3 1/4% ; 3 1/10%

One rule of thumb for estimating crowds is that each person occupies 3 square feet. Use this value to determine the number of people that would fit in a room that is 354in by 714 in.
Answer:
84252 personsStep-by-step explanation:
Given that the dimension of the room is
354in by 714in
let us find the area of the room
A=354x714
A=252,756in^2
The rule say 1 person occupies 3 in^2
hence x person will occupy 252,756in^2
cross multiply we have
3x=252,756
x=252,756/3
x=84252 persons will occupy the room

1. Select all polynomial expressions that are equivalent to 6x4 + 4x2 – 7x² + 5x + 8.
A. 16x10
B. 6x5 + 4x4 – 7x3 + 5x² + 8x
C. 6x4 + 4x3 - 7x2 + 5x + 8
D. 8 + 5x + 7x2 - 4x3 + 6x4
E. 8 + 5x – 7x2 + 4x3 + 6x4
Answer:
Options (C) and (E)
Step-by-step explanation:
Given polynomial is,
6x⁴+ 4x³- 7x² + 5x + 8
So all the polynomials which are (look alike) similar in terms of degree and number of terms to the given expression will be equivalent.
Option (A).
[tex]16x^{10}[/tex]
It's a monomial. So not the answer.
Option (B).
6x⁵ + 4x⁴ - 7x³ + 5x² + 8
This polynomial is a 5th degree polynomial, will not be equivalent to the given polynomial expression with 4 degree.
Option (C).
6x⁴ + 4x³ - 7x² + 5x + 8
All the terms and signs between the terms of this expression are similar to the given polynomial expression,
Expression will be equivalent to the given polynomial expression.
Option (D)
8 + 5x + 7x² - 4x³ + 6x⁴
= 6x⁴- 4x³ + 7x² + 5x + 8
Both are similar in number of terms and degree but signs between the terms are different.
Therefore, both the expressions are will not be equivalent.
Option (E).
8 + 5x - 7x² + 4x³ + 6x⁴
= 6x⁴ + 4x³ - 7x² + 5x + 8
Since, both the polynomials are similar so they are equivalent.

what are the coordnates of D if E (-2,2)is the midpoint of DF and F has the coordnates of (3,5)
Hi there & welcome to brainly!
Answer:
( -7 , -1 )Step-by-step explanation:
Let the co-ordinates of D be ( x , y )
Let D ( x , y ) be ( x1 , y1 ) and F ( 3 , 5 ) be ( x2 , y2 )
Midpoint of DF = E ( -2 , 2 )
Now, finding the co-ordinates of D :
[tex]\boxed{\sf{ midpoint = (\frac{x1 + x2}{2} , \frac{y1 + y2}{2} ) }}[/tex]
⇒ [tex]\sf{ ( - 2 , 2 ) = (\frac{x + 3}{2} , \frac{y + 5}{2} )}[/tex]
Equating corresponding elements, we get :
[tex]\sf{-2 = \frac{x + 3}{2} }[/tex]
⇒ [tex]\sf{ -4 = x + 3 }[/tex]
⇒ [tex]\sf{ x + 3 = -4 }[/tex]
⇒ [tex]\sf{ x = -4 - 3}[/tex]
⇒ [tex]\sf{x = -7 }[/tex]
Again,
[tex]\sf{ 2 = \frac{y+5}{2} }[/tex]
⇒ [tex]\sf{y + 5 = 4 }[/tex]
⇒ y = 4 - 5
⇒ y = -1
Hence, The co-ordinates of D = ( -7 , -1 )

Matt took a train traveling at an average speed of 80 mph from Boston, MA to Washington, D.C. The trip took 6 hours. On his way back to Boston, Matt decides to take an express train that travels at an average speed of 100 mph. How long will the trip home take?
Answer:
The trip will take 4.8 hours
Step-by-step explanation:
Firstly, we need to calculate the distance from Boston to Washington
Mathematically:
Distance = speed * time
Distance = 80 mph * 6 hours = 480 miles
Now we want to calculate the time it will take a train that travels at a speed of 100 mph
Mathematically;
time = distance/speed
time = 480/100 = 4.8 hours

YOUR WELCOME AND PLSSS MARK ME BRAINLIESSSTT!
Help me, pleaseeeeee:)(:
Answer:
X= 128º
Step-by-step explanation:
A triangle is stated to have 180º. This means that since we know 2 sides of the triangle you can simply subtract them from one another.
Doing this you would get: 180 - 90 - 38 = 52º
Noticing that X is on a straight line, this would result in the fact that X is on a line of 180º.
Subtracting the angle we found in the triangle would result you with the answer of:
180 - 52 = 128º for the value of X

isosceles triangles means that the two bottom angles and sides are equal
therefore, you can set R and T equal to each other:
(15x-31)=(9x+11)
(get x to one side)
15x=9x+42
6x=42
x=7
now you can plug x back into the equations:
15(7)-31
105-31
74
R and T = 74
all triangles' internal angles = 180
therefore you can add the two angles then subtract them from 180
74+74=148
180-148=32
S should be 32 :)

Abigail is making a trail mix. She pours 2 15 cups of pretzels, 35 cups of raisins, 1 cup of peanuts, and 45 cups of M&Ms into a bowl. How many total cups of trail mix will she have?
Answer:
296 cupsStep-by-step explanation:
We are expected to solve for the total number of cups, we can achieve this by adding all the individual ingredients together.
Given the number of cups poured
pretzels= 215 cups
raisins= 35 cups
peanuts= 1 cup
M&Ms= 45 cups
So the total is 215+35+1+45= 296 cups
what is six eighths minus one fourth
Answer:
1/2
Step-by-step explanation:
6/8-1/4
6/8-2/8
4/8
or one half
The value of six eights minus one fourth is 1/2
What is expression?An expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.).
Example of expression includes; 5x -2 , 5/2 , x +y . When two ore more terms are joined with an operation,we can call it expression.
six eights = 6/8
one fourth = 1/4
Therefore
of six eights minus one fourth
= 6/8 - 1/4
= 6 - 2/8
= 4/8
divide through by 4
= 1/2
Therefore the value of 6/8-1/4 is 1/2
