The square root of 125 is between
Answer:
[tex] \sqrt{125 } \\ = 11.18[/tex]
It is in between 0 to 12.
Answer:
√125 must be between 11 and 12.
Step-by-step explanation:
Identify perfect squares in the neighborhood of 125:
121 = 11^2 or √121 = 11
144 = 12^2 √144 = 12
√125 must therefore be between 11 and 12.

Calculate the distance between the points E=(-6,8) and N=(-1,5) in the coordinate plane. Give an exact answer (not a decimal approximation).
Answer:
6 units
Step-by-step explanation:
The formula for calculating the distance between two points is expressed as;
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Given the coordinate points E=(-6,8) and N=(-1,5)
[tex]EN = \sqrt{(5-8)^2+(-1+6)^2}\\EN = \sqrt{(-3)^2+(5)^2}\\EN = \sqrt{9+25}\\EN = \sqrt{34}\\EN = 5.8\\EN \approx 6[/tex]
Hence the distance between the points is approximately 6 units

ABCD is a square with an area of 49 cm2, and BE = 4.95 cm. Point E is the midpoint of 2 diagonal lines crossed inside the square.
Answer:
I suppose we want to find the side length of the square.
We know that:
The area of the square is 49cm^2
The distance between one of the vertices of the square and the middle of the square is:
BE = 4.95cm
Now let's remember some things.
For a square of side length L, the area is:
A = L^2
and the diagonal length is:
D = √(2)*L
In this case, we know that half of the diagonal is equal to:
BE = 4.95 cm
Then the diagonal is:
D = 2*BE = 2*4.95cm = 9.9cm
And for the diagonal formula, we have:
D = 9.9cm = √(2)*L
Then the side length is:
L = 9.9cm/√(2) = 7cm
And if we check the area of this square, is:
A = L^2 = (7cm)^2 = 49cm^2
So it checks.
Then we can conclude that the sidelength of the square is 7cm, which means that:
AB = 7cm
BC = 7cm
CD = 7cm
DA = 7cm
A rental car company charges $68.64 per day to rent a car and $0.12 for every mile driven. Jaxon wants to rent a car, knowing that:
•He plans to drive 500 miles
•He has at most $210 to spend
What is the maximum number of days that Jaxon can rent the car while staying within his budget?
Answer:
Step-by-step explanation:
x is the number of miles driven, and I'm assuming that's supposed to say that he plans on driving 500 miles per day and has $210 to spend. We need a cost equation for his trip. $68.64 is the flat fee the company charges regardless of how many miles, x, are driven. If they charge $.12 per mile, that's the rate per mile of the equation which is the same thing as the slope of the linear equation. The cost equation is
y = .12x + 68.64
If he has $210 to spend, let's see how many miles he can go on that by subbing in 210 for y:
210 = .12x + 68.64 and
141.36 = .12x so
x = 1178
He can drive a total of 1178 miles with $210. If he drives 500 miles per day, 1178/500 = 2.356 days. So depending upon when he has to return the car and assuming it's in the morning, he can keep the car for 2 full days and stay within his budget.
Mike and Julie receive $20,000 in gifts from friends and relatives for their wedding. They deposit the money into an account that pays 2.75% interest, compounded daily.
Will their money double within 10 years?
Will their money double within 15 years?
Answer:
A= P(1+r/n)^nt
P=20,000
r=2.75%/100=0.0275
n=365
t= 10 and 15
Will their money double within 10 years?
A=20,000(1+0.0275/365)^365t
=20,000(1.00007534)^365(10)
=26,330.340 --> $26,330.34
No
Will their money double within 15 years?
A=20,000(1+0.0275/365)^365t

WITH THE WORK THO PLEASE?
Answer:
According to the theorem of chords intersecting inside the circle,
1) 15 * 8 = 10 * x
120 = 10x
120/10 = x
12 = x
2) 21 * 10 = 14 * x
210 = 14 x
210/14 = x
15 = x
3)10 * 4 = 5x
40 = 5x
40/5 = x
8 = x
4) 5x * 2x = 10*9
10x^2 = 90
x^2 = 90/10
x^2 = 9
x = √9
x = 3
5)3x + 3 * 3x = 10 * 18
9 x^2 + 9x = 180
dividing the whole eq. by 9
x^2 + x = 20
x^2 + x - 20 = 0
x^2 + 5x - 4x - 20 = 0
x(x + 5) - 4(x + 5) = 0
x - 4 = 0 OR x + 5 = 0
x = 4 or x = -5
The length cannot be negative, so,
x = 4

You and your friend decide to go to Red Robin to eat. You are both part of the rewards club and receive coupons in the mail. You have a coupon a coupon for 10% off the total bill. Your friend has a coupon for $5 off the total bill. Which coupon should you use to save the most money if the total bill was $29.90? *
A. the $5 off coupon
B. the 10% off coupon
C. either one
D. cannot be determined
Answer:
A. the $5 off coupon
Step-by-step explanation:
10% off would only be 2.99 off the bill making it 26.91 but the $5 would take off more
The coupon I would use to save the most amount of money on the total bill is my friend's coupon worth $5.
Which coupon should I use?Coupons reduce the price of an item. An item becomes cheaper after a coupon has been used. In order to determine the better coupon, calculate the price after each coupon has been used.
Coupon 1 : 10% x 29.9 = $3
Coupon 2 : 29.90 - $5 = $24.90

look at the rectangle and the square. ada says the length of diagonal SQ is two times the length of diagonal OM. is ada correct? justify your answer and show all of your work your work should state the serum you use to find the length of the diagonals.
Answer:
No Ada is not correct
Step-by-Step Explanation:
The length of diagonal SQ is not two times the length of diagonal OM. When you split the rectangle using the diagonal you can make a right triangle and use the Pythagorean Theorem to the rest of it.
This would be the Rectangle:
a^2+b^2=c^2
8^2+16^2=c^2
64+256+c^2
320=c^2
√320
17.8
This would be the Square:
a^2+b^2=c^2
8^2+8^2=c^2
64+64=c^2
128=c^2
√128
11.3
Now when I divide these answers that I came up with I get 1.7 which is not equal to 2 therefore SQ is not two times bigger than OM.

Answer:
240 cm^3
Step-by-step explanation:
The solid is composed by two rectangular parallelepipeds. To find the total volume we have to find the volume of the two solids and added up.
To find the volume of a parallelepiped we have to use this formula:
V = base surface x height
The area of rectangle is : base x width
So:
Area first rectangle: 4 x 6 = 24 cm^2
V = 24 x 7 = 168 cm^3
Area second rectangle: 4 x 2 = 8 cm^2
V = 8 x 9 = 72 cm^3
total volume = 168 + 72 = 240 cm^3

On Wednesday 72% of the costumers who bought gas at a gas station made additional purchases. There were 259 costumers made additional purchase?
Answer:
360 approx
Step-by-step explanation:
Given data
We want to find the total number of customers that bought gas
Let the total number of customers be x
So
72% of x = 259
let us solve for x
72/100*x= 259
0.72*x=259
x= 259/0.72
x= 359.72
Hence the actual number of customers is 360 approx
