Answer:
The equation that represents the relation between the figure number, x, and the number of the tiles, y is y = 2x + 1
Step-by-step explanation:
The slope-intercept form of the equation is y = m x + b, where
m is the slope ⇒ constant rate of changeb is the y-interceptIn the given pattern
∵ x represents the figure number
∵ y represents the number of tiles
∵ At x = 1, y = 3
∵ At x = 2, y = 5
∵ At x = 3, y = 7
∵ 5 - 3 = 2 and 7 - 5 = 2
→ That means the constant rate of change is 2
∴ m = 2
→ Substitute it in the form of the equation above
∴ y = 2x + b
→ To find b substitute x and y by the first figure
∵ x = 1 and y = 3
∴ 3 = 2(1) + b
∴ 3 = 2 + b
→ Subtract 2 from both sides to find b
∴ 3 - 2 = 2 - 2 + b
∴ 1 = b
→ Substitute it in the equation
∴ y = 2x + 1
The equation that represents the relation between the figure number, x, and the number of the tiles, y is y = 2x + 1

The sum of two integers is 31. The larger of the two integers is
4 more than 2 times the smaller integer. What are the integers?
Answers
Answer:
The integers are 9 and 22
Step-by-step explanation:
Step one:
given data
let the smaller integer be x
and the bigger be y
x+y=31-----------1
so
y=(2x+4)
Step two:
put y=(2x+4 in equation 1 we have
x+2x+4=31
3x+4=31
3x=31-4
3x=27
divide both sides by 3
x=27/3
x=9
the smaller integer is 9
the bigger is 2(9)+4= 18+4=22

A cube has a volume of 216 cubic inches, and another cube has a volume of 729 cubic inches. What is the ratio of the surface area of the larger cube to the surface area of the smaller cube?
Answers
Answer:
Ratio is [tex]\frac{9}{6}[/tex]
You can simplify it of course to 3/2
Step-by-step explanation:
Volume of a cube is V = length^3 or l^3
Volume for larger cube = 729 cubic inches
Volume for smaller cube = 216 cubic inches
Surface area is S = 6*l^2
So we just need to find the length of each side of the cube.
We take the cube root for each cube volume since there are three sides.
Larger cube = 729^(1/3) = 9
smaller cube = 216^(1/3) = 6
Ratio is [tex]\frac{9}{6}[/tex]

Can someone help me solve multiple step equations? For example (7t - 2) - (-3t + 1) = -3(1 - 3t)
Answers
Answer:
t = 0
Step-by-step explanation:
(7t - 2) - (-3t + 1) = -3(1 - 3t)
because you can not do anything inside the parantheses, you distribute. there aren't any numbers on the left side of the parantheses on the left side of the equation so we just imagine the number 1. on the right side of the equation, just distribute normally
[ 1(7t - 2) -1(-3t + 1) = -3(1 - 3t) ]
will be
7t - 2 + 3t - 1 = -3 + 9t
add like terms
10t - 3 = -3 + 9t
subtract 9t from both sides
t - 3 = -3
add 3 to both sides
t = 0

A machine that fills bottles on an assembly line does so according to a normal distribution, where the mean amount of liquid poured into each bottle is 11.95 ounces with a standard deviation of 0.045 ounces. If more than 12.10 ounces is poured into a bottle, it will overflow and waste the liquid.
Required:
What is the probability that a bottle has more than 12.10 ounces poured into it, causing it to overflow?
Answers
Answer:
The probability is [tex]P( X > 12.10 ) =0.0004[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 11.95 \ ounce[/tex]
The standard deviation is [tex]\sigma = 0.045 \ ounce[/tex]
Generally the probability that a bottle has more than 12.10 ounces poured into it, causing it to overflow is mathematically represented as
[tex]P( X > 12.10 ) = P( \frac{X - \mu }{\sigma } > \frac{ 12.10 - 11.95}{0.045} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
[tex]P( X > 12.10 ) = P( Z > 3.33 )[/tex]
From the z table the area under the normal curve to the right corresponding to 3.33 is
[tex]P( Z > 3.33 ) = 0.0004[/tex]
=> [tex]P( X > 12.10 ) =0.0004[/tex]
Jeremiah is saving money from a tutoring job. After the first three weeks, he saved $135. Assume the situation is proportional. Use the unit rate to write an equation relating the amount saved s to the number of weeks w worked. At this rate, how much will Jeremiah save for eight weeks? *
Answers
Answer:
After the first 3 weeks Jeremiah saved $135. If the situation is proportional:
$135 : 3 = $ 45. It means that he can save $45 for one week.
Therefore an equation is:
s = 45 * w,
where s is the amount saved and w is the number of weeks.
After 8 weeks :
s = 45 * 8 = $360.
