Answer:
A
Step-by-step explanation:
This one is best done by doing a pre factor.
140 = 14 * 10 Now all you need do is factor those two numbers.
140 = 7*2 * 5 * 2
Rearranging this you get 2 * 2 * 5 *7
A
Final answer:
The prime factorization of 140 is found by dividing it by the prime numbers 2, 2, 5, and 7 in sequence, resulting in 2 x 2 x 5 x 7, which corresponds to option A.
Explanation:
The prime factorization of a number is the expression of the number as a product of its prime factors. To find the prime factorization of 140, we can use a factor tree or continuously divide by prime numbers. Beginning with the smallest prime number, 2, we divide 140 by 2 to get 70. Then, we divide 70 by 2 again to get 35. After that, we divide 35 by its smallest prime factor, which is 5, to get 7. Since 7 is already a prime number, we have completed the factorization. So, the prime factorization of 140 is:
2 x 2 x 5 x 7
Therefore, the correct answer is A.2 x 2 x 5 x 7.

ANSWER
D.
[tex]16 {x}^{2} + 24xy + 9 {y}^{2} [/tex]
EXPLANATION
We want to find the expression which is a square of a binomial.
In other words, we want to identify the expression which is a perfect square trinomial.
[tex]16 {x}^{2} + 24xy + 9 {y}^{2} [/tex]
This expression can be rewritten as,
[tex] {(4x)}^{2} + 2(4 \times 3)xy + {(3y)}^{2} [/tex]
This is a perfect square trinomial that can be factored as:
[tex] {(4x)}^{2} + 2(4 \times 3)xy + {(3y)}^{2} = (4x + 3y) ^{2} [/tex]
This is the square of a binomial.
The correct answer is D
The answer is:
D) [tex]16x^{2} +24xy+9y^{2}[/tex]
Why?We are looking for an expression that satisfies the perfect square trinomial form, which can be defined by the following notable product:
[tex](a+b)^{2}=a^{2}+2ab+b^{2}[/tex]
From the given options, we can see that the only option that matches with the perfect square trinomial form is:
[tex]16x^{2} +24xy+9y^{2}[/tex]
We can rewrite the expression by the following way:
[tex](4x+3y)^{2}[/tex]
If we square the binomial, we will have the perfect square binomial expression given from the options.
So, squaring, we have:
[tex](4x+3y)^{2}=(4x)^{2}+2*(4x*3y)+(3y)^{2}\\\\(4x+3y)^{2}=16x^{2} +24xy+9y^{2}[/tex]
Hence, the answer is:
D) [tex]16x^{2} +24xy+9y^{2}[/tex]

The volume ratio of two similar prisms with a surface area ratio of 81:4 is obtained by cubing the square root of the surface area ratio, resulting in a volume ratio of 729:8.
Explanation:The question involves finding the volume ratio of two similar prisms when the surface area ratio is given.
Since the surface areas are in a ratio of 81:4, the corresponding linear dimensions will be in the square root ratio, which is 9:2. For two similar three-dimensional shapes, if the ratio of their corresponding lengths is a:b, then the ratio of their surface areas is a^2:b^2, and the ratio of their volumes is a^3:b^3.
Therefore, the volume ratio of Prism A to Prism B can be found by cubing the linear dimension ratio: (9:2)^3 which equals 729:8. Hence, the volume ratio of Prism A to Prism B is 729:8.

The length of a rectangle is 3 inches longer than its width. If the perimeter of the rectangle is 62 inches , find its length and width
Answer:
Length = 17 inches, Width = 14 inches
Step-by-step explanation:
Let the width(W) of the rectangle be x inches
The length(L) of the rectangle will be x + 3 inches
Perimeter(P) of the rectangle is 62 inches
i.e
P = 2L + 2W
2(x + 3) + 2x = 62
2x + 6 + 2x = 62
4x = 62 - 6 = 56
x = [tex]\frac{56}{4}[/tex] = 14 inches
So the width is 14 inches and;
The length is 14 + 3 = 17 inches
The width of the rectangle is 14 inches, and the length is 17 inches.
Explanation:To find the length and width of a rectangle, we can use the information given in the problem and set up an equation. Let's say the width of the rectangle is x inches. The length would then be x + 3 inches. The formula for the perimeter of a rectangle is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. Plugging in the given values for the perimeter, we get:
62 = 2(x + 3) + 2x
Simplifying the equation:
62 = 2x + 6 + 2x
Combine like terms:
62 = 4x + 6
Subtract 6 from both sides:
56 = 4x
Divide both sides by 4:
x = 14
So the width of the rectangle is 14 inches. Substituting this value back into the equation for the length, we get:
Length = 14 + 3 = 17 inches

A cone has a diameter of 6 inches and a height of 6 inches. Find the volume of the cone to the nearest tenth. Use 3.14 for pie
Final answer:
The volume of a cone with a diameter of 6 inches and a height of 6 inches is approximately 56.5 cubic inches when rounded to the nearest tenth, using the volume formula for a cone.
Explanation:
To calculate the volume of a cone, we can use the formula
V = [tex]\(\frac{1}{3}\)\pi r^2 h[/tex]
First, find the radius (r) by dividing the diameter by 2.
The cone's diameter is 6 inches, thus the radius[tex]\(r = \frac{6}{2} = 3\) inches.[/tex]
Next, apply the values to the cone volume formula:
V =[tex]\(\frac{1}{3}\)\pi (3)^2 \times 6\)[/tex]
Now perform the calculations
V = [tex]\(\frac{1}{3}\)\times 3.14 \times 9 \times 6[/tex]
V = 56.52 cubic inches
Therefore, the volume of the cone is approximately 56.5 cubic inches to the nearest tenth.

Answer:
Because some applicants volunteer and meet the GPA requirements the events are NOT MUTUALLY exclusive. Thus, the probability is 65%
The probability that an applicant meets the GPA requirements or volunteers is 65%.
Explanation:To find the probability that an applicant meets the GPA requirements or volunteers, we need to determine the number of applicants who meet either requirement. From the given information, there are 950 applicants who meet the GPA requirements and 600 applicants who volunteer for community service. However, there are 250 applicants who meet both requirements, so we count them only once.
To find the total number of applicants who meet either requirement, we add the number of applicants who meet the GPA requirements and the number of applicants who volunteer and subtract the number of applicants who meet both requirements:
Total number of applicants who meet either requirement = 950 + 600 - 250 = 1300
The probability that an applicant meets the GPA requirements or volunteers is the number of applicants who meet either requirement divided by the total number of applicants:
Probability = Number of applicants who meet either requirement / Total number of applicants = 1300 / 2000 = 0.65 = 65%

A small business sells dog harness and leashes. The harnesses sell for $7.50, and the leashes sell for $3.25. Last month, the business sold 56 items made $267
Answer:
20 harnesses
36 leashes
Step-by-step explanation:
h = number of harnesses
l = number of leashes
set up two equations based on the information provided:
h + l = 56; since the number of harnesses and leashes made up the total item sold, which is 56
7.5h + 3.25l = 267; the same concept as the last step
h = 56 - l; let one of the variable stand by itself
7.5(56 - l) + 3.25l = 267; substitute the variable h into the other equation
420 - 7.5l + 3.25l = 267; solve
420 - 4.25l = 267; add common variables, remember you take the sign in front of the number when doing math
-4.25l = -153; subtract 420 from both side
l = 36; divide both side by -4.25
36 leashes were sold last month; 56 - 36 = 20, which means 20 harnesses were sold.

Answer:
g(x)=(x+7)^2-3
Step-by-step explanation:
Given:
f(x)= x^2
Now we have to translate f(x) 7 units to the left and 3 units down to form the function g(x).
As per the rules of translation
when any parent function, in given case f(x)=x^2, is translated to 'a' units to the left then 'a' is added to the value of x. thus making f(x+a)
Also when the parent function is translated any 'a' units down then 'a' is subtracted from the value of function. thus making f(x)-a
Translating f(x), 7 units to the left
f(x+7)= (x+7)^2
Translating f(x+7), 3 units down
f(x+7)-3 = (x+7)^2-3
Hence new function g(x)=(x+7)^2-3!

Answer:
x = [tex]\frac{5}{26}[/tex]
Step-by-step explanation:
Given equation:
[tex]\frac{3}{4}x + \frac{5}{8} = 4x[/tex]
[tex]\frac{3(2)x + 5}{8} = 4x[/tex] ∵taking GCF 8
[tex]\frac{8 (6x + 5) }{8}[/tex] = 4x × 8
6x + 5 = 32x ⇒ 5 = 32x - 6x ⇒ 5 = 26x ⇒ x = [tex]\frac{5}{26}[/tex]

In circle O, radius OQ measures 9 inches and arc PQ measures 6 pie inches. What is the measure, in radians, of central angle POQ? edge
The circle has circumference [tex]18\pi\,\mathrm{in}[/tex]. If [tex]m\angle POQ=\theta[/tex], then
[tex]\dfrac{6\pi\,\rm in}{18\pi\,\rm in}=\dfrac\theta{2\pi\,\rm rad}\implies\theta=\dfrac{2\pi}3\,\mathrm{rad}[/tex]
Answer: [tex]\dfrac{2\pi}{3}\text{ radians}[/tex]
Step-by-step explanation:
We know that the formula to calculate the length of arc having central angle 'x' is given by :-
[tex]l=x r[/tex], where r is radius of the circle.
Given : In circle O, radius OQ = [tex]l=9\text{ inches}[/tex]
The measure of arc PQ =[tex]6\pi\text{ inches.}[/tex]
The measure of central angle POQ ( in radians ) is given by :-
[tex]x=\dfrac{l}{r}\\\\\Rightarrow\ x=\dfrac{6\pi}{9}}\\\\\Rightarrow\ x=\dfrac{2\pi}{3}[/tex]
Hence, the measure of central angle POQ =[tex]\dfrac{2\pi}{3}\text{ radians}[/tex]
What is 0.0034 in scientific notation? Pleaseee hurrrryyyyyy
Answer:
3.4 x 10 ^-3
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
The scientific or the exponential form of the number is A = 3.4 × 10⁻³
Given data ,
To express 0.0034 in scientific notation, we need to represent it as a number between 1 and 10 multiplied by a power of 10.
First, we move the decimal point to the right until we have a number between 1 and 10. In this case, we move the decimal point three places to the right, resulting in 3.4.
Next, we determine the power of 10 by counting the number of places we moved the decimal point.
Since we moved it three places to the right, the power of 10 is -3
So , the exponential form is
Putting it all together, 0.0034 in scientific notation is 3.4 × 10⁻³
