A lot is 60 m by 34 m. A house 24 m by 9 m is built on the lot. How much area is left over?
Answer:
Area of the plot = 60m × 34m = 2040sq.m
Area of the house = 24m × 9m = 216sq.m
Area left over = (2040 –216)sq.m = 1824sq.m

Answer:
The sample is calculated by adding the samples and dividing by the number of sample size.
X ± 2.58(6$)/√64
Step-by-step explanation:
Given:
Data were collected by 64 customers for lunch.
Based on past studies, the population standard deviation is known with =∂= $6
a) At 99% confidence
By using given information,
∂= $6, n= 64,
At 99% confidence, the value of z = 2.58
By using formula of margin error:
ME=za/2 ∂/√n
= 2.58 $6/√64
= 15.48/8
=1.935
b) Find the 99% confidence interval for mean amount spent on lunch?
By using given information:
∂= $6, n= 64,
At 99% confidence, the value of z = 2.58
By using the formula:
X ± z∂/√n
Where x is the sample means, z is the %99 confidence level, which is equal to 2.58
The sample is calculated by adding the samples and dividing by the number of sample size.
X ± 2.58(6$)/√64

Step-by-step explanation:
The GCD(a, b) = 9, the LCM(a, b)=378. Find the least possible value of a + b.
========================================================
Work Shown:
I'm assuming your teacher is applying the restriction that both 'a' and 'b' are positive integers.
L = LCM(a,b) = LCM of 'a' and 'b' = 9
G = GCD(a,b) = GCD of 'a' and 'b' = 378
L = (a*b)/G .... this shows how the LCM and GCD are connected
G*L = a*b
a*b = G*L
a*b = 9*378
ab = 3402
b = 3402/a
-------------------
a+b = a + (3402/a)
a+b = (a^2)/a + (3402/a)
a+b = (a^2+3402)/a
Replace 'a+b' with y. Replace every copy of 'a' with x. We get this equation
y = (x^2+3402)/x
Use a calculator or calculus to find that the lowest point occurs at the approximate location (x,y) = (58.3266662412, 116.6533325713)
Check out the diagram below. The graph was made with GeoGebra.
At this point we would stop since we found the lowest y value; however, keep in mind that 'a' and 'b' are integers. There is no way to have a+b add to the non-integer result 116.6533325713
---------------------
What we must do is look at a table of values where we see what integer x values lead to y being an integer as well. Those pairs are
x = 54, y = 117
x = 63, y = 117
Which are highlighted in the same diagram as the graph.
I restricted the table so that [tex]50 \le x \le 60[/tex] due to the lowest point found earlier having an x coordinate of roughly 58.3266662412
Based on what the table says, the smallest a+b can be is 117.
Lynn plotted point G, 3 units to the left and 2 units above point F. Where did lynn plot point G?
Answer:
[tex]G = (2,6)[/tex]
Step-by-step explanation:
See Attachment for Complete Question
From the attachment, we can see that F is plotted at
[tex]F = (5,4)[/tex]
On the x axis, G is 3 units to the left;
And on the y axis, G is 2 units above
So, the coordinates of G is calculated as:
[tex]G = (5-3,4+2)[/tex]
[tex]G = (2,6)[/tex]
Hence:
G is plotted at (2,6)

What is the LCD of 1/2 and2/17
Answer:
the answer would be 34
Step-by-step explanation:
Rewriting input as fractions if necessary:
1/2, 2/17
For the denominators (2, 17) the least common multiple (LCM) is 34.
LCM(2, 17)
Therefore, the least common denominator (LCD) is 34.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
1/2 = 1/2 × 17/17 = 17/34
2/17 = 2/17 × 2/2 = 4/34

How can credit cards be safer than cash? a. It is harder to lose a single credit card than a large number of bills. b. A credit card requires a signature, so it is impossible for anyone other than you to use. c. If a merchant does not hold up their end of an agreement, you can call the credit company and dispute the charges. d. Cash can be miscounted, but credit cards cannot.
Answer:
C. If a merchant does not hold up their end of an agreement, you can call the credit company and dispute the charges
Step-by-step explanation:
Credit cards can be safer than cash because of: c. If a merchant does not hold up their end of an agreement, you can call the credit company and dispute the charges
What is Credit Card?Credit card is a small plastic payment card issued by an individual's bank, which allows the owner of the card to pay a merchant for goods and services, based on the accrued debt of the card owner.
In case a merchant doesn't keep up with an agreement, to be on a safer side, a cardholder can contact the credit company to settle the disputed charges.
Therefore, credit cards can be safer than cash because of: c. If a merchant does not hold up their end of an agreement, you can call the credit company and dispute the charges.

use the following functions: yf(x) = 3x - 7
g(x) = 2x - 4
1. Find (f + g)(x).
2. Find (f - g)(x).
Answer:
(f + g) (x) = 5x - 11
(f - g) (x) = x + 3
Step-by-step explanation:
f(x) = 3x - 7
g(x) = 2x - 4
to find ; (f + g) (x) and (f - g) (x)
now,
(f + g ) (x) = f (x) + g(x)
= (3x - 7) +( 2x - 4 )
= 3x - 7 + 2x - 4
= 5x - 11
again ,
(f - g ) (x) = f(x) - g(x)
= (3x - 7) - (2x - 4)
= 3x - 7 - 2x + 4
= x + 3

Which of the following statements about the function cannot be used to conclude that is defined at x = 1?
a) lim x—>1 f(x) exists
b) f is continuous at x = 1
c) f is differentiable at x = 1
d) the line tangent line to the graph of f at x=1 exists
a) [tex]\lim_{x \to 1} f(x)[/tex] exists
As the limit of a function at any certain point can exist, but the function itself may be not defined at that point.
For example, if [tex]f(x) =\frac{ (x^3 - 1) }{(x - 1)}[/tex], then [tex]\lim_{x \to 1}\frac{(x^3 - 1)}{ (x - 1)} = 3[/tex],
So, here f(1) is undefined as there is a hole in the graph of the function f(x) at the point (1,3).
Therefore the correct statement about the function cannot be used to conclude that is defined at x = 1 is [tex]\lim_{x \to 1} f(x)[/tex] exists.

Give the equation of the line with a slope of
1
7
and a y-intercept of 1.
Answer:
y = 17x + 1
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m = slope
b = y-intercept
Answer:
y=17x+1
Step-by-step explanation:
When a question asks us to give the equation of a line, we usually organize it into this formula:
y=mx+b
This formula is called slope-intercept form. Here's what the variables mean:
y=the y-axis
m=the slope
x=the x-axis
b=the point on the line that crosses the y-axis (the y-intercept)
So to write an equation of a line with a slope of 17 and a y-intercept of 1, we would need to plug those values in as m and b.
y=17x+1

Hunter invested $580 in an account paying an interest rate of 4.6% compounded monthly. Assuming no deposits or withdrawals are made, how much money, to the nearest dollar, would be in the account after 19 years?
Answer: 1388
Step-by-step explanation:
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + R/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
The amount in the account after 19 years is $1388.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + R/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
P = $580
R = 4.6%
n = 12 ( compounded monthly)
t = 19 years
Now,
Convert R as a percent to r as a decimal
r = R/100
r = 4.6/100
r = 0.046 rates per year,
Now,
A = P [tex](1 + R/n)^{nt}[/tex]
A = 580 [tex](1 + 0.046)^{12\times19}[/tex]
A = 580 [tex](1.0046)^{228}[/tex]
A = $1,387.64
Rounding to the nearest dollar we get,
A = $1388
Thus,
The amount in the account after 19 years is $1388.
