Answer is choice CThe length of a picture frame is 8 inches more than the width. For what values of x is the perimeter of the picture frame greater than 152 inches.
For, "x" greater than 34, the perimeter of the picture frame greater than 152 inches
Solution:
Let "x" be the width of the frame
Given that, The length of a picture frame is 8 inches more than the width
Therefore,
Length = width + 8
Length = x + 8
The perimeter of rectangle is given by formula:
Perimeter = 2(length + width)
Substituting the values we get,
Perimeter = 2(x + 8 + x)
Perimeter = 2(2x + 8)
Perimeter = 4x + 16
The perimeter of the picture frame greater than 152 inches
Perimeter > 152
[tex]4x + 16>152\\\\\text{Subtract 16 from both sides of inequality}\\\\4x + 16 - 16 > 152 - 16\\\\4x>136\\\\\text{Divide both sides by 4}\\\\x>34[/tex]
Therefore, for, "x" greater than 34, the perimeter of the picture frame greater than 152 inches
Answer:
x>35

The expression 3 1/2x+18 represents the perimeter of the rectangle shown. Write an expression that represents the length of the rectangle.
Answer:the answer is a
Step-by-step explanation:
Answer:
[tex]1\frac{1}{2}x + 4[/tex]
Step-by-step explanation:
We are given the Perimeter: P = Perimeter[tex]3\frac{1}{2}x + 18[/tex] in decimal 3.5x+18
we know that a Perimeter is equal to all sides added up: S1+S2+S3+S4=P
we know that this is a rectangle so that means that it has 4 sides and two sides are the same and the other 2 are the same.
We are given the the height on the image
Height: H = [tex]\frac{1}{4}x + 5[/tex] in decimal 0.25x + 5
That height is one side so we know another of the sides is the same.
Perimeter is equal to all sides added up. So we have to subtract the sides to find out each ones measurements.
(Height x 2) + (Width x 2) = Perimeter
Therefore we know the height which is given on the image is 0.25x+5 so that times 2 = 0.5x+10 (height x 2)
so now we can subtract the heights from the perimeter.
3.5x + 18
- 0.5x + 10
--------------------
3x + 8
So we got rid of both heights. Now we are left with our two lengths:
3x+8 = (length x 2)
To get the length of one side we divide that by 2 because there are 2 sides that have the same length and get 1.5x+4 in fractions that is:
[tex]1\frac{1}{2}x + 4[/tex]

17x+6y=17 in slope intercept form
Answer:
6y = -17x + 17
Step-by-step explanation:
All you have to do for this equation to put it into slope-intercept form is to minus 17x from both sides giving you 6y = -17x + 17 which is the correct form. Then you can simplify by dividing everything by 6 but I'll let you do that.

To find, the value of [tex]\dfrac{4}{5}[/tex] ÷ [tex]\dfrac{7}{6}[/tex] + [tex]\dfrac{2}{7}.2\dfrac{1}{5}[/tex] = ?
∴ [tex]\dfrac{4}{5}[/tex] ÷ [tex]\dfrac{7}{6}[/tex] + [tex]\dfrac{2}{7}.2\dfrac{1}{5}[/tex]
[tex]=\dfrac{4}{5}\times \dfrac{6}{7} +\dfrac{2}{7}.\dfrac{8}{5}[/tex]
[tex]=\dfrac{24}{35} +\dfrac{16}{35}[/tex]
Taking LCM of denominator, we get
[tex]=\dfrac{24+16}{35}[/tex]
[tex]=\dfrac{40}{35}[/tex]
Dividing numerator and denominator by 5, we get
[tex]=\dfrac{8}{7}[/tex]
∴ The value of [tex]\dfrac{4}{5}[/tex] ÷ [tex]\dfrac{7}{6}[/tex] + [tex]\dfrac{2}{7}.2\dfrac{1}{5}[/tex] [tex]=\dfrac{8}{7}[/tex]
Hence, the value of [tex]\dfrac{4}{5}[/tex] ÷ [tex]\dfrac{7}{6}[/tex] + [tex]\dfrac{2}{7}.2\dfrac{1}{5}[/tex] is equal to [tex]\dfrac{8}{7} .[/tex]

A man drove x miles per hour for 3e hours and (2x-60) miles per hour for the next 4.75 hours. Express the total distance he traveled in terms of x
Answer:
A man drove x miles per hour for 3 hours and (2x-60) miles per hour for the next 4.75 hours.Express the total distance traveled in terms of x.
Total distance covered by the man in terms of 'x' = (12.5x-285)miles
Step-by-step explanation:
Given:
Speed of a man = 'x' miles/hour
Time taken = [tex]3[/tex] hour
So, distance = product of speed and time.
Distance covered in term of 'x' [tex]=(d_1=3x)[/tex]
Now,
Speed = [tex](2x-60)[/tex] miles/hour
Time taken= [tex]4.75[/tex] hours
Distance [tex](d_2)[/tex] = [tex](2x-60)\times 4.75[/tex]
= [tex](2x\times 4.75) -(60\times 4.75)[/tex]
= [tex](9.5x - 285)[/tex] miles
Total distance covered by the man = Summation of [tex]d_1[/tex] and [tex]d_2[/tex]
= [tex](9.5x-285+3x)[/tex]
= [tex](12.5x-285)[/tex] miles
So the total distance covered by the man in terms of 'x' = (12.5x-285) miles.

The recommended angle for a wheelchair ramp is 5 degrees. If the rise of the ramp to go up the steps is 5 feet, find the horizontal run length that the ramp must start. (Round to one decimal place)
Answer:
[tex]57.2\ ft[/tex]
Step-by-step explanation:
we know that
The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)
In this problem
The tangent of angle of 5 degrees is equal to the quotient of "rise over run"
Let
y ----> the rise of the ramp
x ----> the run of the ramp
[tex]tan(5^o)=\frac{y}{x}[/tex]
we have
[tex]y=5\ ft[/tex]
substitute and solve for x
[tex]tan(5^o)=\frac{5}{x}[/tex]
[tex]x=\frac{5}{tan(5^o)}[/tex]
[tex]x=57.2\ ft[/tex]

Evaluate the expression when y=-6.
y² + 7y - 5
When y is equal to -6, the evaluation of the formula [tex]y^2 + 7y - 5[/tex] is -11.
Explanation:In order to assess this mathematical statement when y=-6, we substitute -6 for y in the expression y² + 7y - 5.
In the expression, swap out y for -6. This gives us (-6)² + 7(-6) - 5.Total up each component. 36, 42, and 5 are the results. Addition and subtraction are to be done left to right. 36 - 42 therefore equals -6, and -6 - 5 equals -11.

What is the equation for the line?
Enter your answer in the box.
the graph is below
The equation of a line is y = mx + b [m is the slope, b is the y-intercept or the y value when x = 0 ----> (0, y) or the point where the line goes through the y-axis]
To find the slope, you use the slope formula (m):
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] and plug in 2 points
I will use the points (0, 0) and (1, 8)
(0, 0) ----> (x₁, y₁)
(1, 8) ----> (x₂, y₂)
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{8-0}{1-0}[/tex]
m = 8
Since you know m, plug it into the equation.
y = 8x + b
The graph shows that the y-intercept is 0, so plug it into the equation
y = 8x

Ramon has 7/8 of a cup of cottage cheese. How many 1/4 cup servings can he make?
Answer:
Ramon can make 3 1/2 or 3.5 servings of 1/4 of a cup each one
Step-by-step explanation:
1. What information was given to us to answer the question correctly?
Amount of cottage cheese Ramon has = 7/8 of a cup
2. How many 1/4 cup servings can he make?
For answering this question, we make this calculation:
7/8 * 1/4
7/8 * 4/1 = 28/8 = 7/2 or 3 1/2 cup servings
This means that Ramon can make 3 1/2 or 3.5 servings of 1/4 of a cup each one:
1/4 + 1/4 + 1/4 + (1/2 * 1/4) = 7/8
3/4 + (1/2 * 1/4) = 7/8
3/4 + 1/8 = 7/8
6/8 + 1/8 = 7/8
7/8 = 7/8

b)
Old factory
The growth rate from week 0 to week 1 is 20.
The growth rate from week 1 to week 2 is 22.
New factory:
The growth rate from week 0 to week 1 is 30.

What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Old factory:
f(x) = 223 (1.09)^x
When x = 0,
f(0) = 223(1.09)^0 = 223(1) = 223
In zero weeks, the number of specialties produced is 223.
When x = 1,
f(1) = 223(1.09)^1 = 243.07 = 243
When x = 2,
f(2) = 223(1.09)^2 = 265.32 = 265
When x = 3,
f(3) = 223(1.09)^3 = 290.41 = 290
When x = 4:
f(4) = 223(1.09)^4 = 318.53 = 318
New factory:
(0, 190), (1, 220), (2, 252), (3, 290), (4, 337)
This means,
(0, 190)
In zero weeks, the number of specialties produced is 190.
Thus,
a)
During week 0, the number of specialty items produced at the old factory than at the new factory.
= 223 - 190
= 33
b)
The growth rates in the weekly number of specialty items produced at each factory.
Old factory:
The growth rate from week 0 to week 1 = (243 - 223)/(1 - 0) = 20/1 = 20
The growth rate from week 1 to week 2 = (265 - 243)/(2 - 1) = 22/1 = 22
New factory:
The growth rate from week 0 to week 1 = (220 - 190)/(1 - 0) = 30/1 = 30
The growth rate from week 1 to week 2 = (252 - 220)/(2 - 1) = 32/1 = 32
c)
The weekly number of specialty items produced at the new factory exceeds the weekly number of specialty items produced at the old factory
in week 4.
i.e
f(4) = 223(1.09)^4 = 318.53 = 318

Answer: if your question is the same as mine, it should be correct!
Step-by-step explanation:
(a) 40 more specialty items, as 230 (initial value at the Old Factory) minus 190 is 40.
(b) y2 – y1/x2 – x1
252-220/2-1
32
(c) The new factory seems to have a faster production rate.
(d) Week 3 is the week when the production is faster at the New Factory.
p(w)=230(1.1)^w
p(w)=230(1.1)^3
p(w)=230(1.33100)
p(w)= 306.13
At week 3 for the Old Factory, it seems that there is less production happening than the 3rd week at the New Factory.
