Step-by-step explanation:
The perfect square that is less than 15 is 9 and greater 15 is 16 and the square root of 15 falls between 3 and 4 because 3 times 3 is 9 and 4 times 4 is 16.
First row: 9 < 15 < 16
Second row [tex]\sqrt{9} < \sqrt{15} < \sqrt{16}[/tex]
Third row ; 3 < [tex]\sqrt{15}[/tex] < 4
Is is greater than less or equal to 4.09_4.90

Karen sells tickets at a movie theater. Last night she sold 128 tickets for a total of $1108. Adult's tickets cost $10 and children's tickets cost $6. How many of each kind of ticket did Karen sell?
Answer:
Adult's tickets 85
children's tickets 43
Step-by-step explanation:
x + y = 128
10x + 6y = 1108
x = 128 - y
10(128 - y) + 6y = 1108
1280 - 10y + 6y = 1108
1280 - 4y = 1108
-4y = 1108 - 1280
-4y = -172
y = -172/-4
y = 43
x = 128 - y
x = 128 - 43
x = 85
write in standard form x2 + y = 2x -4
Answer:
y = - x² + 2x - 4
Step-by-step explanation:
The equation of a parabola in standard form is
y = ax² + bx + c ( a ≠ 0 )
Given
x² + y = 2x - 4 ( subtract x² from both sides )
y = - x² + 2x - 4 ← in standard form

please solve for x, and give me an explanation on how you did so? 1/2x-1/3=5/6
=======================================================
Explanation:
Fractions are a pain to deal with, so whenever possible I recommend you eliminate them. With equations like this, you can multiply both sides by the same number to do so. The question is: which number would that be?
If you pick on the LCD, then you'll be able to clear out the fractions. The LCD of 1/2, 1/3, and 5/6 is 6 since the LCM of the denominators is 6.
Multiply both sides by 6 to get
(1/2)x - 1/3 = 5/6
6*[ (1/2)x - 1/3 ] = 6(5/6)
6*(1/2)x - 6*(1/3) = 6(5/6)
3x - 2 = 5
------------
At this point, the fractions are gone. We can now solve like so
3x-2 = 5
3x-2+2 = 5+2 ... adding 2 to both sides
3x = 7
3x/3 = 7/3 .... dividing both sides by 3
x = 7/3
Answer:
x=5/6
Step-by-step explanation:
12x−13=5612x-13=56
Combine 1212 and xx.
x2−13=56x2-13=56
Move all terms not containing xx to the right side of the equation.
Add 1313 to both sides of the equation.
x2=56+13x2=56+13
To write 1313 as a fraction with a common denominator, multiply by 2222.
x2=56+13⋅22x2=56+13⋅22
Write each expression with a common denominator of 66, by multiplying each by an appropriate factor of 11.
Multiply 1313 and 2222.
x2=56+23⋅2x2=56+23⋅2
Multiply 33 by 22.
x2=56+26x2=56+26
Combine the numerators over the common denominator.
x2=5+26x2=5+26
Add 55 and 22.
x2=76x2=76
Multiply both sides of the equation by 22.
2⋅x2=2⋅

Point K is on line segment JL. Given JK = 5x + 7, JL = 2x+8, and KL = 4,
determine the numerical length of JL.
Answer:
The numerical length of JL is 6 units
Step-by-step explanation:
Here, we want to determine the numerical length of JL
Mathematically;
JL = JK + KL
2x + 8 = 5x + 7 + 4
2x + 8 = 5x + 11
5x -2x = 8-11
3x = -3
x = -1
But JL = 2x + 8
JL = 2(-1) + 8 = -2 + 8 = 6

At Becky's Restaurant, 10 out of 25 customers order wheat rolls. The rest of the customers order cornbread. Which does NOT represent the part of the customers who order wheat rolls
Answer:
C. 25 ÷ 10
Step-by-step explanation:
A. 10/25
B. 2/5
C. 25 ÷ 10
D. 0.4
Total customers at Becky's restaurant = 25
Customers who order wheat rolls = 10
It means 10 out of 25 customers order wheat rolls
That is
10 / 25
Dividing both numerator and denominator by 5
= 2 / 5
2/5 in decimal
= 0.4
The option Which does NOT represent the part of the customers who order wheat rolls
is 25/10
Option C. 25 ÷ 10
A researcher randomly selected 30 people to participate in a study to investigate which of two materials, A or B, used in the heels of sneakers will last longer. The researcher is considering two design types for the study.
Design 1: Randomly assign 15 participants to wear sneakers with material A on their left feet and material B on their right feet. The remaining participants will wear sneakers with material B on their left feet and material A on their right feet.
Design 2: Randomly assign 15 participants to wear sneakers with material A on both feet and the remaining participants to wear sneakers with material B on both feet.
Which of the following best describes each design?
Answer:
Design 1
Step-by-step explanation:
Design one would work better because the students get to see both materials (each on one foot) and if they do the same things each day with both feet, they can test how the material works with the activity...If that makes sense
The question is an illustration of a random selection.
The descriptions of the designs are:
Design 1 is a matched pair designDesign 2 is a completely randomized design.Design 1
From the question, we understand that:
15 participants wear material A on the left feet, and material B on the right feet.The other 15 wear material B on the left feet, and material A on the right feet.The above description is a matched pair design, because half of the participants gets randomly assigned to material A and B, while the other half gets automatically assigned to the remaining materials.
Design 2
From the question, we understand that:
15 participants wear material A on both feetThe other 15 wear material B on both feetThe above description is a completely randomized design, because half of the participants gets randomly assigned to material A, while the other half gets randomly assigned to material B.

=> 10^½(1 +1/10)^½
WE KNOW THAT:

need help please help
Answer:
9 minutes
Step-by-step explanation:
The water volume in pool 1 starts at 50 gallons and increases at 2.3 gallons per minute. An expression for that volume could be ...
v = 50 +2.3t
The water volume in pool 2 starts at 102.2 gallons and decreases at 3.5 gallons per minute. An expression for that volume could be ...
v = 102.2 -3.5t
The volumes will be equal when ...
50 +2.3t = 102.2 -3.5t
5.8t = 52.2 . . . . . . . . . . . subtract 50-3.5t from both sides
t = 52.2/5.8 = 9 . . . . . . . divide by the coefficient of t
After 9 minutes, the pools will contain the same amount of water.
_____
The equation 5.8t = 52.2 tells you the 52.2 gallon difference in volumes is being reduced at the rate of 5.8 gallons per minute. You don't really need the 'v' equations to figure that out.

Antony borrowed 20,000,000 for 7 years his interest rate is 5% how much interest will he pay in all
Answer:
7,000,000
Step-by-step explanation:
[tex]Principal = 20,000,000\\Time =7\:years\\Rate = 5\%\\Simple\:interest =?\\\\Simple\:interest = \frac{Principal\times Rate\times Time}{100} \\\\S.I= \frac{20000000\times 5 \times 7}{100} \\\\S.I==\frac{700000000}{100}\\\\Simple\: interest=7000000[/tex]
The solution is, he will pay 7000000 interest in all.
What is interest?Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.
Here, we have,
formula: I = Prt.
here, we have,
given that,
Antony borrowed 20,000,000 for 7 years his interest rate is 5%
i.e. we get,
P= 20,000,000
t = 7
r= 5%
and, we have to find I
so, we have,
I = P r t
=20,000,000*5*7/100
=7000000
Hence, he will pay 7000000 interest in all.
