A rectangular magazine cover is photocopied by using a scale factor of One-third. The length of the photocopy of the magazine cover is enlarged by a factor of 3. enlarged by a factor of One-third. reduced by a factor of 3. reduced by a factor of One-third.
Answers
Answer: "reduced by a factor of One-third."
Step-by-step explanation:
Suppose that the original magazine has a length L and a width W.
If it is photocopied using a scale factor of K, then the measures of the photocopy will be:
length = K*L
Width = K*W
In this case, the scale factor is K = 1/3, then the measures of the photocopy will be:
length = (1/3)*L = L/3
Width = (1/3)*W = W/3
For usual notation:
When k > 1, we have an enlargement by a factor k
when 0 < k < 1, we have a reduction by a factor k
in this case, k = 1/3, then:
We have a reduction by a factor of 1/3
The correct option is:
"reduced by a factor of One-third."
Answer: D-reduced by a factor 1/3

Answers

Step-by-step explanation:
Answer:
2 x 2 x 5 x 5
Step-by-step explanation:
since 2, 3, and 5 are prime numbers I always begin by seeing if the number to be factored has those as factors
100 is divisible by 2 so you can start there:
2 x 50
50 is divisible by 2 so you now have:
2 x 2 x 25
25 is divisible by 5 so you now have all prime factors whose product is 100

Answer:
y=(-4/3)x+2
Step-by-step explanation:
we have two points (3,-2) and (0,2) given from the statement
the equation of the lines is:
y=mx+b
m=slope
m=(y2-y1)/(x2-x1)
m=(2-(-2))/(0-3)
so we have the slope is
m=4/-3 =-4/3 =-1.3333
we need to find "b"
using the point (0,2)
we have :
2=m*0+b
2=b
finally, we have
the answer is y=(-4/3)x+2
2a) Solve using substitution.
y = 2

Frank and his family went on vacation one summer, and drove 3,000 miles in 10 days. If they drove an equal distance every day, how many miles a day did frank and his family drive.
Answers
Answer:
Distance cover by Frank and family each day = 300 miles per day
Step-by-step explanation:
Given:
Total distance cover by Frank and family = 3,000 miles
Number of days = 10
Find:
Distance cover by Frank and family each day
Computation:
Distance cover by Frank and family each day = Total distance cover by Frank and family / Number of days
Distance cover by Frank and family each day = 3,000 / 10
Distance cover by Frank and family each day = 300 miles per day
Answer:
C. 300
Step-by-step explanation:
Divide the distance by the time it took to travel that distance: 3,000 miles ÷ 10 days = 300 miles per day.

Find the inequality represented by the graph.
Answers
Answer:
[tex]y<-\frac{4}{3}x+5[/tex]
Step-by-step explanation:
Since, the given line in the graph is a dotted, line will represent an inequality with no sign of equal to (=).
Since, the shaded area is below the dotted line, inequality will have the sign less than (<).
Therefore, equation of the inequality will be in the form of,
y < mx + b
Here, m = slope of the line
b = y-intercept
Slope of the line passing through two points (0, 5) and (3, 1),
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{5-1}{0-3}[/tex]
= [tex]-\frac{4}{3}[/tex]
Y-intercept (at x = 0),
b = 5
Therefore, equation of the inequality will be,
[tex]y<-\frac{4}{3}x+5[/tex]

what is the y intercept of x+ 7y = 35
Answers
Answer:
5
Step-by-step explanation:
get the equation into slope intercept form, y = mx +b
where b is the y-intercept
subtract x from both sides
7y = -x + 35
divide 7 from both sides
y = -1/7 x + 5
thus b = 5
5
Explanation:
A linear equation is typically organized in the form y=mx+b. In this equation, b represents the y-intercept. Our goal is to rearrange the given equation into this form to identify b.
x+7y=35
Subtract both sides by x
x+7y-x=-x+35
7y=-x+35
Divide both sides by 7
7y/7=-1/7x+35/7
y=-1/7x+5
Now, we can tell clearly that the y-intercept of the equation is 5.

Find the sum of the first 8 terms of the series 3 + 6 + 9 + …, given that a8 = 24.
Answers
Step-by-step explanation:
You want to use the sum of an arithmetic sequence formula.
(a1 + an) × n/2
a1 is the first term and an is the last term. n is the number of terms.
In this case: (3+24) × 8/2 = 27×8/2 = 27×4 = 108
The sum of the first 8 terms of the series 3 + 6 + 9 + ... is 108.
To find the sum of the first 8 terms of the series, we need to find the common difference (d) and then use the formula for the sum of an arithmetic series.
Given that [tex]\(a_8 = 24\)[/tex], we can see that the 8th term is 24.
The formula for the nth term of an arithmetic series is [tex]\(a_n = a_1 + (n-1) \cdot d\)[/tex], where [tex]\(a_n\)[/tex] is the nth term, [tex]\(a_1\)[/tex] is the first term, and d is the common difference.
Substitute n=8 and [tex]\(a_n=24\)[/tex] into the formula:
[tex]\(24 = 3 + (8-1) \cdot d\)[/tex]
Simplify the equation:
[tex]\(24 = 3 + 7 \cdot d\)[/tex]
Now, solve for d:
[tex]\(7d = 24 - 3\)\\\\\(7d = 21\)\\\\\(d = \frac{21}{7} = 3\)[/tex]
Now that we have the common difference d = 3, we can use the formula for the sum of an arithmetic series:
[tex]\(S_n = \frac{n}{2} \cdot (a_1 + a_n)\)[/tex]
Substitute [tex]\(n=8\)[/tex], [tex]\(a_1=3\)[/tex], and [tex]\(a_n=24\)[/tex] into the formula:
[tex]\(S_8 = \frac{8}{2} \cdot (3 + 24)\)\\\\\(S_8 = 4 \cdot 27\)\\\\\(S_8 = 108\)[/tex]
So, the sum of the first 8 terms of the series is 108.

Step-by-step explanation:
2x + 1 = 16
2x = 15 (subtract 1 on both sides)
x = 7.5 (divide 2 om both sides)
Since 7.5 is not an integer, (a) is No.
However 7.5 is rational, therefore (b) is Yes.
Answer:
