The area of a rectangle is the product of its length and width. Both length and width are whole numbers. A rectangular poster has an area of 204 square inches. The width of the poster is greater than 10 inches and is prime. What is the width of the poster?
Answer:
17 inches.
Step-by-step explanation:
If the area of a rectangle is the product of its length and width, then;
Area of a rectangle = Length × Width
Given that the width of the poster is greater than 10 inches and is prime, this means and W>10
Area of the rectangle = 204in²
On substituting the values in the formula;
A = LW
204 = LW
Since W is greater than 10 and is prime, it can be between the prime numbers 11, 13 and 17. Note that L must be a whole number as well for any number to be the right answer we seek.
Let's test each values of the prime width that will give a length that is a whole number.
If W = 11
204 = 11×L
L = 204/11
L = 18.54
Since the length didn't give us a whole number, this means our width is not 11.
If W = 13
204 = L × 13
L = 204/13
L = 15.69
Also, we can see that the length is not also a whole number for the value of 13 as the prime width.
If W = 17
204 = L × 17
L = 204/17
L = 12
It can be seen that the length of the rectangle gave us a whole number when we used the prime width of 17, hence the width of the poster that is greater than 10 inches and is prime that makes both length and width to be a whole number is 17 inches.
Answer:17 inches

Solve for r. 7(r+1) = 20.3
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{r = 1.9}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{7(r + 1) = 20.3}[/tex]
Distribute 7 through the parentheses
⇒[tex] \sf{7r + 7 = 20.3}[/tex]
Move 7 to right hand side and change it's sign
⇒[tex] \sf{7r = 20.3 - 7}[/tex]
Subtract 7 from 20.3
⇒[tex] \sf{7r = 13.3}[/tex]
Divide both sides of the equation by 7
⇒[tex] \sf{ \frac{7r}{7} = \frac{13.3}{7} }[/tex]
Calculate
⇒[tex] \sf{r = 1.9}[/tex]
Hope I helped!
Best regards!!
r is 1.9
Solve 7(r+1) = 20.3
Remove the brackets by dividing both sides by 7:
7(r+1) / 7 = 20.3 / 7
r + 1 = 2.9
Take 1 to the other side so that you can be left with r. When you do this, the sign will change from positive to negative:
r = 2.9 - 1
r = 1.9
r is therefore 1.9

a saleswoman earns 60% commission on all that she sells. Last month she sold $400 worth of merchandise. How much commission (In dollars) did she earn last month?
Answer:
$240
Step-by-step explanation:
If she earns 60% commission, that means she only earns 60% of all sales. So if you take that 60% or (.60) you can multiply that 400 by .60, that equates to 240.
what is the percentage of the total variation in candy bar sales explained by the regression model? a. 78.39% b. 88.54% c. 100% d. 48.19%
Complete question :
A candy bar manufacturer is interested in trying to estimate how sales are influenced by the price of their product. To do this, the company randomly chooses 6 small cities and offers the candy bar at different prices. Using candy bar sales as the dependent variable, the company will conduct a simple linear regression on the data below:
City - - - - - Price ($) -- - Sales
River City - - 1.30 - - - - - - 100
Hudson - - - 1.60 - - - - - 90
Ellsworth - - - 1.80 - - - - - 90
Prescott - - - - 2.00 - - - - 40
Rock Elm - - 2.40 - - 38
Stillwater - - 2.90 - - 32
Answer:
78.39%
Step-by-step explanation:
what is the percentage of the total variation in candy bar sales explained by the regression model?
The question could be interpreted as meaning the percentage of the total variation in the dependent variable (candy bar sales) which can be explained by the regression model. Hence the independent variable is price. This variance can be known by calculating the Coefficient of determination (R^2) value of the regression model.
To save computation time, the R^2 value can be obtained using an online Coefficient of determination calculator.
To obtain the R^2 value, the values of the dependent and independent variables are entered. The R^2 value obtained is : 0.7839
Therefore the total proportion of variance in candy bar sales explained by the regression model is 0.7839 which is equivalent to:
(0.7839 * 100) = 78.39%

Please Help ASAP it's my Math HW
Step-by-step explanation:
Use segment addition/subtraction:
GK = GJ − HJ + HK
GK = 2x + 5 − x + 4x − 1
GK = 5x + 4
If GK = 39, then the value of x is:
39 = 5x + 4
5x = 35
x = 7
Use segment subtraction to find GH and JK.
GH = GJ − HJ
GH = 2x + 5 − x
GH = x + 5
GH = 12
JK = HK − HJ
JK = 4x − 1 − x
JK = 3x − 1
JK = 20
Find an equation of the sphere that passes through the point (7, 1, −3) and has center (5, 6, 5).
Answer:
The equation of the sphere that passes through the point (7,1,-3) and center at (5, 6, 5) is [tex](x-5)^{2}+(y-6)^{2}+(z-5)^{2} = 93[/tex].
Step-by-step explanation:
Any sphere centered at [tex](h,k,s)[/tex] in an Euclidean space with a radius [tex]r[/tex] is represented by the following formula:
[tex](x-h)^{2} +(y-k)^{2}+(z-s)^{2} =r^{2}[/tex]
If [tex](x,y,z) = (7,1,-3)[/tex] and [tex](h,k, s) = (5,6,5)[/tex], the radius of the sphere is obtained:
[tex](7-5)^{2}+(1-6)^{2}+(-3-5)^{2} = r^{2}[/tex]
[tex]r^{2} = 93[/tex]
[tex]r = \sqrt{93}[/tex]
The equation of the sphere that passes through the point (7,1,-3) and center at (5, 6, 5) is [tex](x-5)^{2}+(y-6)^{2}+(z-5)^{2} = 93[/tex].

The depth of Sam's from the surface is 23 feet.
We are given that Ben and Sam are diving in a lake.
Ben and Sam are 14 feet below the surface.
But after a while, Ben spots Sam 9 feet directly below him.
We have to find sam's depth from the surface.
Let the depth at which both Ben and Sam were diving in the lake be X.
i.e X = 14 feet.
Let the depth of Sam from Ben be Y.
i.e Y = 9 feet.
Now Sam's depth from the surface would be:
= X + Y
= 14 + 9
= 23 feet.
Thus, the depth of Sam's from the surface is 23 feet.

Answer:
-4-5
Step-by-step explanation:
The temp was at -4 and if it dropped that means you subtract another 5 from it which is -4-5
Answer:
The correct answer is -4 - 5.
Step-by-step explanation:
The original temperature is -4 degrees. Then, the temperature falls by 5 degrees. The temperature "falling" means that it is getting colder or that the temperature is getting lower. This lets us know that we need to use subtraction. The final answer is -4 - 5, which would give us the temperature of -9 degrees as the new temperature.
