What is the area of the following trapezoid?

280 mm2
420 mm2
140 mm2
210 mm2

Answer:

Correct choice is 11/12.

Step-by-step explanation:

Given numbers are 2/3, 11/12, 5/6 and 7/12.

Now we need to find about which time is faster among 2/3, 11/12, 5/6 and 7/12.

To find that we need to make denominators equal.

2/3, 11/12, 5/6, 7/12

Common denominator is 12 so let's multiply by suitable numbers to get equal denominator.

8/12, 11/12, 10/12, 7/12

Now we see that largest numerator is 11.

Hence correct choice is 11/12.

The probability that it will be a clear day in San Antonio in May is 0.57 or 57%, calculated by dividing the number of clear days (17) by the total number of days in May (30).

In order to determine the probability of a clear day in San Antonio in May, we need to use the given data. From option OA, it is stated that there are 17 clear days out of 30. Probability is calculated by dividing the number of favorable outcomes (clear days) by the total number of outcomes (total days in May).

So, if we divide 17 (the number of clear days) by 30 (the total number of days in May), we get the probability as 0.57 after rounding to two decimal places which matches option OA.Therefore, the probability that it will be clear in San Antonio in May is 0.57 or 57%.

Answer:

3x^2+13x+12 square feet.

Step-by-step explanation:

Since the formula for area is lxw so we Multiply the given using the foil method: (3x+4)(x+3)

3x^2+9x+4x+12, combine like terms

3x^2+13x+12, since we no longer have other like terms then the area is 3x^2+13x+12 square feet.

Answer:

Area of rectangle = [tex]3x^2+13x+12[/tex] square feet

Step-by-step explanation:

We are given the following dimensions of a rectangle and we are to find its area:

[tex] ( 3 x + 4 ) feet [/tex]

[tex] ( x + 3 ) feet [/tex]

We know that the formula of area of a rectangle is given by: [tex]l \times w[/tex].

Substituting the given dimensions in the above formula.

Area of rectangle = [tex](3x+4) \times (x+3)[/tex] = [tex]3x^2+9x+4x+12[/tex] = [tex]3x^2+13x+12[/tex] square feet

The equation of the line parallel to 3x + y = 7 and passing through (-3,3) is y = -3x + 12 (Option A) because parallel lines have identical slopes and using the point-slope formula provides us with the y-intercept.

To find the equation of a line parallel to 3x + y = 7 and passing through the point (-3,3), we need two pieces of information:

The slope of the parallel line

The coordinates of a point it passes through

First, let's rewrite the given equation in slope-intercept form to find the slope. Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

y = -3x + 7

So, the slope m is -3. Because parallel lines have the same slope, our new line will also have a slope of -3.
Using the slope (-3) and the given point (-3,3), we apply the point-slope formula:

y - y1 = m(x - x1)

y - 3 = -3(x - (-3))

y - 3 = -3x - 9

y = -3x + 12

Thus, the equation in slope-intercept form for the line that passes through (-3,3) and is parallel to 3x + y= 7 is y = -3x + 12 which corresponds to Option A.

Answer:

99.7%

Step-by-step explanation:

The 68-95-99.7 rule refers to what percentage of data is contained within ranges a certain distance from the mean.

68% of the data lies within one standard deviation of the mean

95% lies within two standard deviations, and

99.7% lies within three standard deviations.

Our mean here is 600, and our standard deviation is 120, so those ranges would be:

480-720 for 1 standard deviation

360-840 for 2 standard deviations, and

240-960 for 3.

Our given range is 240 to 960, three standard deviations from the mean, so the 68-95-99.7 rule tells us that this range contains 99.7% of the people.

According to the empirical rule, approximately 99.7% of people taking the GRE score between 240 and 960.

The student is asking for the percentage of people taking the GRE who score between 240 and 960 using the 68-95-99.7 Rule (also known as the empirical rule). This rule applies to normally distributed data and indicates that approximately 68% of data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.

For the GRE, with a mean score of 600 and standard deviation of 120, one standard deviation range is from 480 to 720, two standard deviations is from 360 to 840, and three standard deviations is from 240 to 960. Using this rule:

68% of the scores fall between 480 (600-120) and 720 (600+120).

95% of the scores fall between 360 (600-2*120) and 840 (600+2*120).

99.7% of the scores fall between 240 (600-3*120) and 960 (600+3*120).

Hence, according to the empirical rule, approximately 99.7% of people taking the GRE score between 240 and 960.

Answer:

29.3 in³

Step-by-step explanation:

1. Volume of cone: V = ¹/₃ * πr²h

2. Find r: r = d/2 = 4/2 = 2 in

3. Plug in: V = ¹/₃ * π(2)²*7

4. Powers: V = ¹/₃ * π * 4 * 7

5. Multiply: V = ²⁸/₃π in³ ≈ 29.3 in³ (excluding outside of the cone)

Final answer:

Approximately 29.3 cubic inches of ice cream can fit in the chocolate cone.

Explanation:

To find the amount of ice cream that can fit in a chocolate cone, we need to calculate the volume of the cone. The volume of a cone is given by the formula V = (1/3)πr^2h, where r is the radius (half the diameter) of the base of the cone and h is the height of the cone. In this case, the diameter is 4 inches, so the radius is 2 inches. The height of the cone is 7 inches. Plugging these values into the formula, we get V = (1/3)π(2^2)(7) = (4/3)π(7) = 28/3π ≈ 29.3 cubic inches. Therefore, approximately 29.3 cubic inches of ice cream can fit in the chocolate cone.

To get the right answer just solve all the equations, even the one in the question. And match the one that is equivalent.

Note:

If you are reading this, please let me know if you need to know anything else.

Mark BRAINLIEST

Check the picture below.

For this case we have the following equation:

[tex]4 ^ {(x-2)} = 8 ^ 6[/tex]

We must create equivalent expressions in the equation, so that they have equal bases:

[tex]2 ^ {2 * (x-2)} = 2 ^ {3 * 6}[/tex]

If the bases are the same, then the two expressions are only equal if the exponents are equal:

[tex]2 (x-2) = 3 * 6\\2 (x-2) = 18\\2x-4 = 18\\2x = 18 + 4\\2x = 22\\x = \frac {22} {2}\\x = 11[/tex]

Answer:

[tex]x = 11[/tex]

Option D

Answer: OPTION D

Step-by-step explanation:

You need to remember the following:

[tex]a^x=a^y\\x=y[/tex]

 Then, you must descompose 4 and 8 into their prime factors:

[tex]4=2*2=2^2\\8=2*2*2=2^3[/tex]

Rewriting the expression:

[tex]2^{2(x-2)}=2^{3(6)}[/tex]

Now you get:

[tex]2(x-2)=3(6)[/tex]

Finally, you must solve for the variable "x".

Therefore, you get the following result:

[tex]2x-4=18\\2x=22\\x=11[/tex]

Answer:

3) -19 - 17i is our answer

Step-by-step explanation:

to solve A - BC we plug in the values given

A= -3 + 5i

B = 4 - 2i

C = 1 + 6i

-3 + 51i - (4 - 2i)(1 + 6i) is our expression. we can FOIL (4 - 2i)(1 + 6i) this expression out. FOIL stands for:

First

Outside

Inside

Last

i will highlight the terms i am using in the current step in bold and put the result next of those two terms next to the expression

F: (4 - 2i)(1 + 6i) = 4

O: (4 - 2i)(1 + 6i) = 24i

I: (4 - 2i)(1 + 6i) = -2i

L: (4 - 2i)(1 + 6i) = 12 < --- the reason why its 12 and not -12i or 12i is because i = √-1 and i² = -1

when we multiply -2i * 6i, we would have gotten a -12i², and i² = -1, so we are multiplying -12 by -1, which gives us 12 as the result

combining all these terms together and we have:

4 + 24i - 2i + 12

in the expression this is:

-3 + 5i - (4 + 24i - 2i + 12) < we need to distribute the negative sign into (4 + 24i - 2i + 12) and we now get:

-3 + 5i -4 - 24i + 2i - 12 < combine like terms (ex: i terms together)

-3 - 4 - 12 = -19

5i - 24i + 2i = -17i

the result of the expression is:

-19 - 17i

we cannot simplify this any further so this is our answer. the answer choice that matches this is 3, so 3) -19 - 17i is our answer

The result of the expression where i is the imaginary unit is -19-17i. Option 3 is correct

Given the following complex numbers A = -3 + 5i, B = 4 - 2i, and C = 1 +6i

We need to solve for A - BC

BC = (4 - 2i)(1 + 6i)

BC = 4(1) + 4(6i) - 2i(1) - 2i(6i)

BC = 4 + 24i -2i - 12(-1)

BC = 16+22i

Evaluate A - BC

A - BC = (-3 + 5i) - (16 + 22i)

A - BC = -3-16 + 5i - 22i

A - BC = -19 - 17i

Hence the result of the expression where i is the imaginary unit is -19-17i

A. The graphs of two of the functions have a minimum point.

Step-by-step explanation:

Option A is false, because the only function that has a minimum point is
