Answer:
D. 3(x+2) can be rewritten as 3x + 6 using the distributive property
Step-by-step explanation:
Given
[tex]3(x + 2) = 3x + 6[/tex]
Required
Explain
From the list of given options, option D answers the question.
This is because, the expression above involves distributive property and only option D correctly states that.
A distributive property is:
[tex]a*(b + c) = a*b + a * c[/tex]
In this case:
[tex]a = 3[/tex] [tex]b = x[/tex] and [tex]c = 2[/tex]
So:
[tex]a*(b + c) = a*b + a * c[/tex]
Substitute values for a, b and c
[tex]3*(x + 2) = 3 * x + 3 * 2[/tex]
[tex]3(x + 2) = 3x + 6[/tex]
Answer:
C. Both expressions involve addition.

helpp
Answer:
24
Step-by-step explanation:
Let’s write them as numbers
6/1/4
Dividing by 4 means multiplying by its reciprocal.
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.

If the probability is 0.65 that a marriage will end in divorce within 20 years, what is the probability that out of 7 couples just married in the next 20 years
(A) None will be divorced?
(B) All will be divorced?
(C) Exactly 6 will be divorced?
(D) At least 6 will be divorced?
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
Which is the best estimate of the product of the fractions? StartFraction 4 Over 7 EndFraction times StartFraction 8 Over 9 EndFraction times StartFraction 14 Over 15 EndFraction
Answer:
Product = [tex]\dfrac{64}{135}[/tex]
Step-by-step explanation:
The expression is as follows :
[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
So, it will become :
[tex]4\times \dfrac{8}{9}\times \dfrac{2}{15}\\\\=\dfrac{4\times 8\times 2}{9\times 15}\\\\=\dfrac{64}{135}[/tex]
So, the product of the given fractions is [tex]\dfrac{64}{135}[/tex].

Speed= 1/3/1/6
Speed= 1/3*6/1
multiply the numerator by the inverse of the denominator
Speed=6/3
Speed= 2 miles per hour

A 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?
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

If the fraction 414/x-10 is equivalent to -23 , find the value of x. Show your work. Use reasoning to find x.
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

0-4-9 = -13 or -4-9 = -13
Explanation:
Basically it starts at 0, then it moves to the left of the number line meaning it subtracts. It moves to the left by 4, so it is subtracting 4 from 0. Then it moves to the left again by 9, so you subtract 9 from 0-4
In the end, it is 0-4-9 or you can remove the 0 and be -4-9

Step-by-step explanation:
A plane takes off from an airport on the bearing S 29°W. It continues for 20 minutes then changes to bearing S 52°W and flies for 2 hours 20 minutes on this course then lands at a second airport. If the plane's speed is 420 mph, how far from the first airport is the second airport? Round to the nearest mile.
A. 1011 mi
B. 1111 mi
C. 1010 mi
D. 1110 mi
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
