If the fraction 414/x-10 is equivalent to -23 , find the value of x. Show your work. Use reasoning to find x.
Answers
Answer:
x = -8
Step-by-step explanation:
Solve for x by getting rid of the fraction.
414/(x-10) = -23
414 = -23(x-10)
414 = -23x + 230
184 = -23x
-8 = x

5·x³/x² = 5·x = 5·2 = 10A farmer wants to build a rectangular pen which will be bounded on one side by a river and on the other three sides by a single-strand electric fence. If the farmer has 40 meters of wire to use, what is the largest area that the farmer can enclose?
Answers
Answer:
A) Dimensions;
Length = 20 m and width = 10 m
B) A_max = 200 m²
Step-by-step explanation:
Let x and y represent width and length respectively.
He has 40 metres to use and he wants to enclose 3 sides.
Thus;
2x + y = 40 - - - - (eq 1)
Area of a rectangle = length x width
Thus;
A = xy - - - (eq 2)
From equation 1;
Y = 40 - 2x
Plugging this for y in eq 2;
A = x(40 - 2x)
A = 40x - 2x²
The parabola opens downwards and so the x-value of the maximum point is;
x = -b/2a
Thus;
x = -40/2(-2)
x = 10 m
Put 10 for x in eq 1 to get;
2(10) + y = 40
20 + y = 40
y = 40 - 20
y = 20m
Thus, maximum area is;
A_max = 10 × 20
A_max = 200 m²
The area of the pen is the product of its dimensions
The largest area the farmer can enclose is 200 square meters
The perimeter of the pen is given as:
[tex]\mathbf{P = 40}[/tex]
Because one side of the fence is covered by a river, the perimeter would be:
[tex]\mathbf{2x + y = 40}[/tex]
Make y the subject
[tex]\mathbf{y = 40 - 2x}[/tex]
The area of the pen is:
[tex]\mathbf{A = xy}[/tex]
Substitute [tex]\mathbf{y = 40 - 2x}[/tex]
[tex]\mathbf{A = x(40 - 2x)}[/tex]
Expand
[tex]\mathbf{A = 40x - 2x^2}[/tex]
Differentiate
[tex]\mathbf{A' = 40 - 4x}[/tex]
Set to 0
[tex]\mathbf{ 40 - 4x = 0}[/tex]
Rewrite as:
[tex]\mathbf{ 4x = 40}[/tex]
Divide through by 4
[tex]\mathbf{x = 10}[/tex]
Substitute 10 for x in [tex]\mathbf{A = x(40 - 2x)}[/tex]
[tex]\mathbf{A = 10 \times (40 - 2(10))}[/tex]
[tex]\mathbf{A = 200}[/tex]
Hence, the largest area the farmer can enclose is 200 square meters

Step-by-step explanation:
() means to multiply
So, -3(5) = -3 x 5 = -15
Answer: -15
The question asks you to find the "product," which means the result of multiplying. Both the word "product" and the parentheses indicate that you have to multiply.
Since it's a negative (-) multiplied by a positive (+), your product will be negative (-).
So, -3(5) = -15.

[tex]\dfrac{4}{7}\times \dfrac{8}{9}\times \dfrac{14}{15}[/tex]
We need to find the product of the above expression
As 7 × 2 = 14

A. 1011 mi
B. 1111 mi
C. 1010 mi
D. 1110 mi
Answers
Answer: 1110 miles
Step-by-step explanation:
Given that :
Speed (V) = 420 mph
t1 = 20 minutes = 20/60 = 0.3333 hour
t2 = 2 hours 20 minutes = 2.333 hours
Distance = speed * time
d1 = 420 * 0.333 = 140 miles
d2 = 420 * 2.33333 = 979.98 = 980 miles
Using cosine rule :
x = sqrt(d1² + d2² - 2(d1 * d2) cos 157
x = sqrt(140^2 + 980^2 - 2(140 * 980) cos157
x = sqrt(1232586.5)
x = 1110.2191
x = 1110 miles

(D) At least 6 will be divorced?
Answers
Answer:
0.00064
0.049
0.185
0.234
Step-by-step explanation:
Using binomial distribution formula :
P(x = x) = nCx * p^x * (1 - p)^(n-x)
p = 0.65
1 - p = 1 - 0.65 = 0.35
n = 7
(A) None will be divorced?
P(x = 0) : 7C0 * 0.65^0 * 0.35^7
= 1 * 1 * 0.00064339296875
= 0.00064
(B) All will be divorced?
P(x = 7) : 7C7 * 0.65^7 * 0.35^0
1 * 0.04902227890625 * 1
= 0.049
(C) Exactly 6 will be divorced?
P(x = 6) : 7C6 * 0.65^6 * 0.35^1
7 * 0.075418890625 * 0.35
= 0.18477628203125
= 0.185
(D) At least 6 will be divorced?
P(x ≥ 6) = p(6) + p(7)
P(6) = 0.185
P(7) = 0.049
P(x ≥ 6) = 0.185 + 0.049 = 0.234

Reciprocal of a number: Can be found when you switch the positions of the denominator and numerator
So reciprocal of 1/4=4/1=4
Next, we multiply by its reciprocal
6*4=24
Therefore, 6 divided by one fourth is 24.
