Rewrite the expression in the form 7^n
7^2 x 7^6
Answer:
The expression in the form [tex]7^n[/tex]
[tex]7^2\times \:\:7^6=7^n[/tex]
Step-by-step explanation:
[tex]7^2\:\times \:7^6[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\times \:a^c=a^{b+c}[/tex]
[tex]7^2\times \:7^6=7^{2+6}[/tex]
So the expression becomes

A large water tank holds 210 liters of water. About how many gallons of water does the same tank hold, if there are approximately 15 liters in 4 gallons?
Answer:
Step-by-step explanation:
Set up a proportion
15 Liters / 4 gallons = 210 Liters / x Cross Multiply
15x = 4 * 210 Combine the right
15x = 840 Divide by 15
x = 840 / 15
x = 56 gallons
If the width of the dining room table is w feet, and the length is 3w - 2 feet, write an algebraic expression that represents the perimeter of the table
The required algebraic expression that represents the perimeter of the dining room table is 8w - 4.
What is the perimeter?Perimeter is the measure of the figure on its circumference.
Here,
The perimeter of a rectangle is given by the formula P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.
Substituting the given expressions for the length and width of the dining room table, we get:
P = 2(3w - 2) + 2w
Simplifying the expression, we get:
P = 6w - 4 + 2w
Combining like terms, we get:
P = 8w - 4
Therefore, the algebraic expression that represents the perimeter of the dining room table is 8w - 4.

In the first ten months of the year, people took out 427,113 books from the Brookton Library. The librarian would like to set a new record and have 500,000 books go out in one year. If 38,264 books are taken out in November, how many must go out in December to meet the librarian's goal?
Answer:72,887
Step-by-step explanation: 500,000 - 427,113 = 72,887
Answer:
34,623 books
Step-by-step explanation:
First, add the amount taken out in November to the amount from the first 10 months of the year.
427,113 + 38,264
= 465,377
Then, subtract this from 500,000:
500,000 - 465,377
= 34,623
So, to meet the librarian's goal, 34,623 books need to go out in December.
Explain how you know these two figures are similar.

RDN’s sales of cable modem in San Mateo, California, for the months of January through April were as follows:January February March April 50 80 70 60Suppose exponential smoothing is used with a smoothing constant (alpha) of 0.30. If the forecast for January were 50, the forecast for May would be approximately:a. 51.60b. 59.04c. 60d. 53.08e. 50
To calculate the exponential smoothing forecast for May, we need to use the formula Therefore the correct option is A 51.60 .
[tex]Ft = alpha * Xt + (1 - alpha) * Ft-1[/tex] Where: - Ft is the forecast for time period t - Xt is the actual sales for time period t - Ft-1 is the forecast for the previous time period (t-1) - alpha is the smoothing constant Given that the forecast for January is 50, we can calculate the forecast for February as follows: [tex]F1 = 0.30 * 50 + (1 - 0.30) * 50 = 50[/tex] Similarly, we can calculate
the forecasts for March and April: F2 [tex]= 0.30 * 80 + (1 - 0.30) * 50 = 65[/tex] F3 [tex]= 0.30 * 70 + (1 - 0.30) * 65 = 66.50[/tex] F4 [tex]= 0.30 * 60 + (1 - 0.30) * 66.50 = 63.05[/tex] Now, to calculate the forecast for May: F5 [tex]= 0.30 * Xt-1 + (1 - 0.30) * Ft-1 F5 = 0.30 * 60 + (1 - 0.30) * 63.05 F5 ≈ 51.60[/tex] Therefore, the forecast for May using exponential smoothing with a smoothing constant of 0.30 is approximately 51.60 (option a).
Hence the correct option is A

A florist uses 225 branches of winterberry to make 75 wreaths. Based on the ratio or unit rate, how many branches of winterberry will the florist use for 25 wreaths?
Answer:
the number of branches required to use 25 wreaths is 75 branches
Step-by-step explanation:
Given that
The florist used 225 branches of winterberry for making 75 wreaths
First we have to compute the unit rate or the ratio
= 225 ÷ 75
= 3 : 1
Now the number of branches required to use 25 wreaths is
= 3 × 25
= 75 branches
Hence, the number of branches required to use 25 wreaths is 75 branches
Jack's goal is to lose 4.25 pounds every month. If he keeps this up, how much weight will he have lost after 9.5 month
round to the nearest hundredth
Answer:
40.38 pounds
Step-by-step explanation:
9.5 x 4.25 = total weight lost
9.5 x 4.25 = 40.375 = 40.38 pounds
Two sidewalks in a park are represented by lines on a coordinate grid. Two points on each of the lines are shown in the tables. Sidewalk 1 x y 2 5 0 1 Sidewalk 2 x y 1 3 3 -3 (a) Write the equation for Sidewalk 1 in slope-intercept form. (b) Write the equation for Sidewalk 2 in point-slope form and then convert to slope-intercept form. (c) Is the system of equations consistent independent, coincident, or inconsistent? Explain. a. Note: Review 2.11 Strange Solutions and 5.04 Classifying Systems if you’re not sure where to start. (d) Use the substitution or elimination method to solve your system, and explain which one you picked. If the two sidewalks intersect, what are the coordinates of the point of intersection? Answer:
Answer:
y = 2x + 1 ;
y - 3 = - 3(x - 1) ; y = - 3x + 6 ;
Independent ;
(1, 3)
Step-by-step explanation:
Given the data:
Sidewalk 1:
x __ y
2 _ 5
0 _ 1
Sidewalk 2:
x __ y
1 _ 3
3 _ -3
Equation for sidewalk 1 in slope - intercept form:
Slope intercept form:
y = mx + c
c = intercept ; m = slope
m = (change in y / change in x)
m = (1 - 5) / (0 - 2) = - 4 / - 2 = 2
Y intercept ; value of y when x = 0
(0, 1) ; y = 1
Hence, c = 1
y = 2x + 1
Sidewalk 2:
Point slope form:
y - y1 = m(x - x1)
m = slope
m = = (-3 - 3) / (3 - 1) = - 6/2 = - 3
Point (x1, y1) = (1, 3)
y - 3 = - 3(x - 1)
To slope intercept form:
y - 3 = - 3(x - 1)
y - 3 = - 3x + 3
y = - 3x + 3 + 3
y = - 3x + 6
Since the slope of both lines are different, intersection will be at single point and will have a single solution. This makes it independent.
Using substitution method :
y = 2x + 1 - - - (1)
y = - 3x + 6 - - - (2)
Substitute (1) into (2)
2x + 1 = - 3x + 6
2x + 3x = 6 - 1
5x = 5
x = 1
From (1)
y = 2(1) + 1
y = 2 + 1
y = 3
Coordinate of the point of intersection = (1, 3)
