Given that:
Larger square is a dilation of smaller square
Dimension of smaller square (5 - 3) units by (5 - 3) units = 2 by 2
Dimension of larger square (7 - 1) units by (7 - 1) units = 6 by 6
Hence, the scale factor used to create the larger square from the smaller square will be:
Scale factor (x) * side of smaller square = side of larger square
x * 2 = 6
2x = 6
x = 6/2
x = 3
Hence, scale factor used to generate larger square is 3

Mary has some money to purchase furniture for her home. She bought a television that cost $1400. She spent 40% of the remaining money on a bed. If the bed cost 25% as much as the total amount of money she had at first. What is the difference between the cost of the television set and the bed?
Answer:
The difference $2.733.30
Step-by-step explanation:
Let the total money be x
The remaining money will be (x-1400)
40% of this on a bed
= 40/100 (x-1400)
= 0.4(x-1400)
cost of bed is 25% of x
Thus;
0.4(x-1400) = 25/100 * x
0.4(x-1400) = 0.25x
0.4x - 560 = 0.25x
0.4x-0.25x = 560
= 0.15x = 560
x = 560/0.15
So the difference between the tv and. bed, will be ;
560/0.15 - 1400
= (560-210)/0.15 = $2,333.33

Lupita bought 7 pounds of pretzels at a local wholesaler for $16.80. Her friend Charles bought 5 pounds of pretzels at the supermarket for $12.75. Charles thinks he got the better deal because $12.75 is less than $16.80. 8a. Is Charles's reasoning correct? Explain why or why not.
Answer:
Charly has the better buy
Step-by-step explanation:
The unit cost is
=16.8/7
=$2.4
Her friend Charles bought 5 pounds of pretzels at the supermarket for $12.75
Unit cost
=12.75/5
=$2.55
Charly got the best deal because the unit cost per item is less than that of the friend
Your brother traveled 117 miles in 2.25 hours to come home for Christmas. What's the average speed that he was traveling?
Answer:
52 miles per hour
Step-by-step explanation:
The formula for Average speed is given as: Distance(miles)/Time in hours
From the question,
Distance = 117 miles
Time = 2.25 hours
Average Speed = 117 miles/2.25 hours
Average Speed = 52 miles per hour
The average speed that he was traveling is 52 miles per hour

Can someone help me with this math problem? “Solve the equation for y, if it’s not already solved for. If already solved for, type already solved.”
the equation: 5x+3y=15
Answer:
y=(-5/3x)+5
Step-by-step explanation:
so you want to isolate the variable of y.
5x+3y=15
5x+3y-5x=15-5x
3y=-5x+15
3y/3=(-5x+15)/3
y=(-5/3x)+5

Write the simplest polynomial function for each set of zeros
Zeros = -2, 5, -1
Answer:
The polynomial is ;
x^3 -2x^2 -13x - 10
Step-by-step explanation:
Given the zeros, we set them to equal zero so as to get the linear factors
Mathematically, that will be as follows;
x = -2
x + 2
x = 5
x-5
x = -1
x + 1
So we have the polynomial as;
(x + 1)(x + 2)(x-5)
= (x -5)(x^2 + 3x + 2)
= x^3+ 3x^2 + 2x -5x^2 -15x - 10
= x^3 -2x^2 -13x - 10
A polynominal function that describes an enclosure is v(x)=1500x_x2 where x is the length of the fence in feet what is the maximum area of the enclosure
Answer:
The answer is below
Step-by-step explanation:
A polynominal function that describes an enclosure is v(x)=1500x-x2 where x is the length of the fence in feet what is the maximum area of the enclosure
Solution:
The maximum area of the enclosure is gotten when the differential with respect to x of the enclosure function is equal to zero. That is:
V'(x) = 0
V(x) = x(1500 - x) = length * breadth.
This means the enclosure has a length of x and a width of 1500 - x
Given that:
v(x)=1500x-x². Hence:
V'(x) = 1500 -2x
V'(x) = 0
1500 -2x = 0
2x = 1500
x = 1500 / 2
x = 750 feet
The maximum area = 1500(750) - 750² = 562500
The maximum area = 562500 feet²
Answer:
562500 feet²

The value of tan 60° in the triangle ABC is √3
Right angle triangle:Right angle triangle have one of its angles as 90 degrees. The sides are called hypotenuse, adjacent and opposite side base on the angles.
Therefore,
ΔABC
∠C = 90°
AB = 12
BC = 6
∠B = 60°
∠A = 30°
Therefore,
tan 60° = opposite / adjacent
AC = √12² - 6² = √108 = 6√3
tan 60° = AC / BC
tan 60° = 6√3 / 6
tan 60° = √3

There are 159 students to be grouped in math teams. Each team is to have the same number of students. Can each team have 3, 4, 5 or 6 students?
Answer:
3 students for each team
Step-by-step explanation:
Answer:
Each team can have 3 students.
Step-by-step explanation:
159 students grouped in three's = 159/3=53
The same thing goes for if they were grouped in 4's, 5's, or 6's.
159/4=39.75 159/5=31.8 159/6=26.5
And since you cant divide single students into splits objects, 3 is
the only solution that works.
