Two possible floor plans for a new bathroom are shown.
Is there a value for x for which the perimeters are equal?
What is the linear equations?
Answer:
Hope it works for u
Step-by-step explanation:
As we have given two shapes bathroom
square and rectangle
Parameter of square= sum of all the sides ( : In square all sides are equal
Parameter of square= 4*L = 4*(x+3) (:L=x+3
similarly,
In rectangle opposites sides are equal hence
Perimeter of rectangle= 2*length+2*width ( : length=x+4,width can't be seen clearly so I assume and take it width=x+1 hope this is equal to the width of ur question otherwise do the calculation by ur self).
Perimeter of rectangle= 2*(x+4)+2(x+1)
so now we have to find the value of "x" for which both perimeter are equal, so
perimeter of square= perimeter of rectangle
4*(x+3)=2*(x+4)+2(x+1) we can also write as
2(x+3)+2(x+3)=2(x+4)+2(x+1)This is the linear equation requirednow to find value of "x"simplify both sides, we get4x+12=4x+100≠2 so that not true and also there is no value of "x"for which both parameters become equal
so from my side "b" option is correctPlease brain-list it if u find it help-full it requires effort!
Answer: B option is correct. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.
explanation: I hope that was helpful!

Find the percent change to the nearest whole percent. from 45 feet to 95 feet.
Answer:
211%
Step-by-step explanation:
To calculate the percentage change between these two numbers we need to divide the end result from the initial starting point. Once we do this we need to multiply the product by 100 to get the percentage value.
95 / 45 = 2.11111
2.11111 * 100 = 211.11%
Finally, we can see that the percentage change from 45 ft. to 95 ft. is 211.11%. If we round this to the nearest whole percent it would be a change of 211%
Which shows all the values of x that make the rational expression 2x^2-72/5x^2-245 underlined
Answer:
7 and -7
Step-by-step explanation:
Correct question
Which shows all the values of x that make the rational expression 2x^2-72/5x^2-245 undefined
For the expression to be undefined, the denominator must be equal to zero
Hence 5x² - 245 =0
Add 245 to both sides
5x²-245+245 = 0+245
5x² = 245
x² = 245/5
x² = 49
x = ±√49
x =7 and -7
Hence the values of x that will make the function undefined are 7 and -7

Solve the triangle. Round your answers to the nearest tenth.
Answer:
Angles: [tex]\angle A = 43^{\circ}[/tex] [tex]\angle B = 55^{\circ}[/tex] [tex]\angle C = 82^{\circ}[/tex]
Sides: [tex]BC = 20[/tex] [tex]AB = 29[/tex] [tex]AC =24[/tex]
Step-by-step explanation:
See attachment for complete question
From the attachment, we have:
[tex]AB = 29[/tex]
[tex]AC =24[/tex]
[tex]\angle C = 82^{\circ}[/tex]
Required
Complete the missing side and missing angles
To calculate angle B, we apply sine laws:
[tex]\frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}[/tex]
In this case:
[tex]\frac{AB}{sinC}=\frac{AC}{sinB}[/tex]
This gives:
[tex]\frac{29}{sin(82^{\circ})}=\frac{24}{sinB}[/tex]
[tex]\frac{29}{0.9903}=\frac{24}{sinB}[/tex]
Cross Multiply
[tex]sinB * 29 = 24 * 0.9903[/tex]
Divide both sides by 29
[tex]sinB = \frac{24 * 0.9903}{29}[/tex]
[tex]sinB = 0.8196[/tex]
Take arcsin of both sides
[tex]B = sin^{-1}(0.8196)[/tex]
[tex]B = 55^{\circ}[/tex]
So:
[tex]\angle B = 55^{\circ}[/tex]
To solve for the third angle, we make use of:
[tex]\angle A + \angle B + \angle C = 180^{\circ}[/tex]
This gives:
[tex]\angle A + 55^{\circ} + 82^{\circ} = 180^{\circ}[/tex]
[tex]\angle A + 137^{\circ}= 180^{\circ}[/tex]
[tex]\angle A = 180^{\circ}- 137^{\circ}[/tex]
[tex]\angle A = 43^{\circ}[/tex]
Hence, the angles are:
[tex]\angle A = 43^{\circ}[/tex] [tex]\angle B = 55^{\circ}[/tex] [tex]\angle C = 82^{\circ}[/tex]
To calculate the length of the third side, we apply cosine law
[tex]BC^2 = AB^2 + AC^2 - 2*AB*AC*cosA[/tex]
[tex]BC^2 = 29^2 + 24^2 - 2*29*24*cos(43^{\circ})[/tex]
[tex]BC^2 = 841+ 576 - 1392*cos(43^{\circ})[/tex]
[tex]BC^2 = 841+ 576 - 1392*0.7314[/tex]
[tex]BC^2 = 841+ 576 - 1018.11[/tex]
[tex]BC^2 = 398.89[/tex]
Take the square root of both sides
[tex]BC = \sqrt{398.89[/tex]
[tex]BC = 19.9722307217[/tex]
[tex]BC = 20[/tex]
Sarah buys a shirt on sale at Jersey's. The original price was $28, but the shirt is on sale for 30% off. If there is a 5% sale tax, how much did Sarah pay for the shirt?
Answer:
$20.58
Step-by-step explanation:
28 x 0.30 = 8.4
28 - 8.4 = 19.6
19.6 x 0.05 = 0.98
19.6 + 0.98 = 20.58

A) 4(x – 3) = -28
B) 7 = 3x + 11 – 8x + 4x
C) (2x – 16) =-6
D) 19x – 21 + 10 – 15x = -10

In a fruit cocktail, for every 25 ml of orange juice you need 30 ml of apple juice and 45 ml of coconut milk. What proportion of the cocktail is apple juice?
Give your answer as a fraction in its simplest form.
Answer:
The proportion of apple juice
[tex]p = \frac{3}{10} = 0.3[/tex]
Step-by-step explanation:
Given that fruit cocktail, for every 25ml of orange juice
Given that 30ml of apple juice
Given that 45ml of coconut milk
we need to find the proportion of apple juice
The proportion of apple juice
[tex]p = \frac{x^{-} }{n} \\ = \frac{30}{100} \\[/tex]
[tex]p = \frac{3}{10}[/tex]
The proportion of apple juice [tex]p = \frac{3}{10}[/tex]

A falling object travels a distance given by the formula d=3t+5t2, where d is measured in feet and t is measured in seconds. How many seconds will it take for the object to travel 84 feet?
Answer:
Approximately 3.81 seconds
Step-by-step explanation:
d = 3t + 5t²
d = 84
84 = 3t + 5t²
3t + 5t² - 84 = 0
5t² + 3t - 84 = 0
5(t² + 3/5t - 84/5) = 0
5(((t + 3/10)² - 9/100) - 84/5) = 0
5((t + 3/10)² - 9/100 - 84/5) = 0
5((t + 3/10)² - 9/100 - 1680/100) = 0
5((t + 3/10)² - 1689/100) = 0
5(t + 3/10)² - 1689/20 = 0
5(t + 3/10)² = 1689/20
(t + 3/10)² = 1689/100
t + 3/10 = ±√(1689)/10
t = -3/10 ± √(1689)/10
t = -3/10 ± ≈41.1/10
t = -3/10 ± ≈4.11
t ≈ -0.3 ± 4.11
t [can only be positive] ≈ 4.11 - 0.3
t ≈ 3.81

Determine whether each equation represents a linear or nonlinear function.
Equation Linear Non - linear
y = 2x³ + 1 No Yes
y = 3x Yes No
y = x/5 Yes No
What is a function?A function is a relationship between inputs where each input is related to exactly one 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,
y = 2x³ + 1
For x = 1, 2, 3,
y = 2 + 1 = 3
y = 2 x 2³ + 1 = 2 x 8 + 1 = 17
y = 2 x 3³ + 1 = 2 x 27 + 1 = 54 + 1 = 55
The rate of change.
Between 3 and 17 = 17 - 3 = 14
Between 17 and 55= 55 - 17 = 38
This means the equation is not linear.
y = 3x
For x = 1, 2, 3,
y = 3 x 1 = 3
y = 3 x 2 = 6
y = 3 x 3 = 9
The rate of change.
Between 3 and 6 = 6 - 3 = 3
Between 6 and 9 = 9 - 6 = 3
This means the equation is linear.
y = x/5
For x = 1, 2, 3,
y = 1/5
y = 2/5
y = 3/5
The rate of change.
Between 1/5 and 2/5 = 2/5 - 1/5 = 1/5
Between 2/5 and 3/5= 3/5 - 2/5 = 1/5
This means the equation is linear.
Thus,
y = 2x³ + 1 is a linear equation.
y = 3x is not a linear equation.
y = x/5 is a linear equation.
