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.
Answer:
11/12 is the answer
Step-by-step explanation:
Samara is adjusting a satellite because she finds it is not focusing the incoming radio waves perfectly. The shape of her satellite can be modeled by y^2=2(x+6), where x and y are modeled in inches. She realizes that the static is a result of the feed antenna shifting slightly off the focus point. What is the focus point of the satellite?
Answer:
(-5.5,0)
Step-by-step explanation:
The question is on finding the focus point of a parabola
Given y²= 2(x+6).....................................(a)
Compare equation (a) with the standard equation (y-b)²= 2p(x-a)
y²= 2(x+6)------can be written as (y-0)²=2(x+6)
(y-0)²=2(x+6)
(y-b)²= 2p(x-a)
2p=2-----------------divide both sides by 2 to get p
p=2/2=1
For the vertex (a,b)⇒(-6,0)
For the focus point ( a+p/2, b)........................................(b)
Substitute values i equation (b) above
(-6+1/2 ,0) =(-5.5, 0)

Answer:
A. 10 fluid ounces
Step-by-step explanation:
One fluid ounce is equal to one quart. This means she had 64 fluid ounces in her jug. She poured 6 3/4 fluid ounces in 8 mugs, so you would multiply 6 3/4 by 8 to get 54. Now you go back to the original amount, 64, and subtract 54 from that. 64 minus 54 equals 10. I hope this helped!

if a frog can move 1/4 of a mile every hour, then how many hours would it take for a frog to go 2 miles?
Answer: 8 hours
Step-by-step explanation: If a frog can jump 1/4 fourth a mile every hour then it will take 4 hours to complete a mile. But because we are talking a bout 2 miles, you have to double the time. Therefore, the answer is 8 hours
It would be one hour every quarter of the mile so count the hours by the amount of numbers there are in one mile so it would be 8 hours

What value of x would make the expression below equal to 8? Photo provided! 20points!
For this case, we must find the value of "x" so that the given expression is equal to 8.
That is to say:
[tex](\sqrt [5] {8 ^ 3}) ^ x = 8[/tex]
We apply "ln" to both sides of the equation to remove the exponent variable:
[tex]ln ((\sqrt [5] {8 ^ 3}) ^ x) = ln (8)\\xln (\sqrt [5] {8 ^ 3}) = ln (8)\\xln (\sqrt [5] {512}) = ln (8)[/tex]
We rewrite 512 as:
[tex]512 = 32 * 16 = 2 ^ 5 * 16\\xln (\sqrt [5] {2 ^ 5 * 16}) = ln (8)[/tex]
By definition of power properties we have:
[tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]
So:
[tex]xln (2 \sqrt [5] {16}) = ln (8)[/tex]
We clear x:
[tex]x = \frac {ln (8)} {ln (2 \sqrt [5] {16})}[/tex]
In decimal form, [tex]x = 1.6[/tex] periodic number
ANswer:
[tex]x = \frac {ln (8)} {ln (2 \sqrt [5] {16})}\\x = 1.6\ periodic\ number[/tex]

Answer:
118°
Step-by-step explanation:
Since it is an isosceles triangle, two angles must be the same.
Also angles in a triangle add up to 180° and from this we can deduce that
x + ( 31 + 31 ) = 180
( Simplify )
x + 62 = 180
( - 62 from both sides )
x = 118°

Answer:
AB = 17.3 cm
Step-by-step explanation:
We require to find the measure of ∠A then use the cosine ratio to calculate AB
sum the parts of the ratio 3 + 2 = 5 parts, then
90° ÷ 5 = 18° ← value of 1 part of ratio
∠A = 2 × 18° = 36°, thus
cos36° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{14}{AB}[/tex]
Multiply both sides by AB
AB × cos36° = 14 ( divide both sides by cos36° )
AB = [tex]\frac{14}{cos36}[/tex] ≈ 17.3 cm

Recycling center a processes aluminum at rate of 100 pounds per hour, while recycling center b processes aluminum at a rate of 2 tons per week. Assuming that both centers operate all day every day, which center processes aluminum faster, and why?
Answer:
Center a processes it faster
Step-by-step explanation:
Center B math: 2 tons as pounds is 4000 pounds.
4000/7=571.43 pounds a day
571.43/24=23.81 pounds a hour
23.81 pounds per hour is less than 100 pounds an hour. so center a is the faster one.
Answer:
Center A process aluminium faster
Because
Center A process 8.4 Tons of aluminium per week while center B processes 2 tons per week
Step-by-step explanation:
Topic: Unit Conversion
Given
Center A Rate of Processing Aluminium
A = 100 pounds per hour
Center B Rate of Processing Aluminium
B = 2 tons per week
To solve this question, the following assumptions will be made
Both centers operate 24 hours a dayBoth centers operate 7 days a weekHaving said that, the first step is to make conversions.
We either convert pounds to tons or tons to pounds.
Converting Center A Rate of Processing Aluminium from Pounds to Tons
1 Pound = 0.0005 Tons
So, 100 Pounds = 0.0005 * 100
100 Pounds = 0.05 Tons.
So, Center A Rate of Processing Aluminium is 0.05 Tons per hour
Before we make comparison, both must be in the same unit.
i.e. either in Tons per hour or Tons per units.
Converting Center A Rate of Processing Aluminium from Tons per hour to Tons per week
There are 24 hours a day;
So, Center A Rate of Processing Aluminium is 0.05 Tons/hr* 24 hr/day
Converting Center A Rate of Processing Aluminium is 1.2 Tons / day
There are 7 days a week;
So, Center A Rate of Processing Aluminium is 1.2 Tons/ day * 7 days / week
Converting Center A Rate of Processing Aluminium is 8.4 Tons / week
At this point, we have the following
Center A Rate of Processing Aluminium = 8.4 Tons / week
Center B Rate of Processing Aluminium = 2 tons per week
By Comparison,
8.4 Tons per week is greater than 2 tons per week; So, Center A process aluminium faster
How to find the area of a triangle on a coordinate plane
Equation of Area of Triangle = 1/2 x b x h
Find the base by counting the boxes across the bottom.
Find the height by counting the boxes from the base (bottom) to highest point on the triangle.
Insert those numbers into the equation and you get your answer.
To find the area of a triangle on a coordinate plane, you can use the formula: Area = 1/2 * base * height. The base can be any side of the triangle, and the height is the perpendicular distance from the base to the opposite vertex. We can calculate the lengths of the base and height by using the coordinates of the triangle's vertices.
Explanation:To find the area of a triangle on a coordinate plane, we can use the formula: Area = 1/2 * base * height. The base can be any side of the triangle, and the height is the perpendicular distance from the base to the opposite vertex. We can calculate the lengths of the base and height by using the coordinates of the triangle's vertices.
For example, if the coordinates of the vertices are (x1, y1), (x2, y2), and (x3, y3), we can find the length of the base by calculating the distance between (x1, y1) and (x2, y2). Then, we can find the height by calculating the distance between (x3, y3) and the line containing the base. Finally, we substitute the values of the base and height into the formula to find the area.
Suppose the coordinates of the triangle are (1, 2), (4, 6), and (7, 2). We can find the base and height as follows:
Base: Distance between (1, 2) and (4, 6) = sqrt((4 - 1)^2 + (6 - 2)^2) = sqrt(9 + 16) = sqrt(25) = 5 unitsHeight: Distance from (7, 2) to the line containing the base (1, 2) and (4, 6) = perpendicular distance from (7, 2) to the line = 2 units (since the line is parallel to the x-axis)Now, substitute the values into the formula: Area = 1/2 * base * height = 1/2 * 5 * 2 = 5 units^2. Therefore, the area of the triangle is 5 square units.

What is the equation of the midline for the function y = 3cos(x - π ) - 4?
y = -4
y = -π
y = 4
y = π
Answer:
The correct answer option is y = -4.
Step-by-step explanation:
We are to find the equation of the mid-line for the following function:
[tex]y=3cos(x-\pi)-4[/tex]
[tex]3 cos((x - \pi ) - 4 = 3 cos(x) - 4[/tex] because [tex]cos(x-\pi) = cos(x)[/tex]
[tex]-1 \leq cos(x) \leq 1[/tex]
[tex]-3 \leq 3cos(x) \leq 3[/tex]
[tex]-3-4 \leq 3 cos(x)-4 \leq 3-4[/tex]
[tex]-7 \leq 3 cos(x)\leq-1[/tex]
The range is -7 to -1 so the midpoint is [tex]\frac{-7-1}{2} =-4[/tex]
Therefore, the equation of the mid-line for the given function is y = -4.

B.
The enlarged picture has a length of inches.
C.
The enlarged picture has a length of inches.
plz solve soon i only have one min left to answer
Answer:
enlarge the picture 7 times by inches
To enlarge Tonya's picture by a factor of 7, the length of 4 1/5 inches is multiplied by 7 to get an enlarged length of 29 2/5 inches.
Tonya has a small picture with a length of 4 1/5 inches. To enlarge the picture by a factor of 7, we need to multiply the original length by 7. First, we convert 4 1/5 inches to an improper fraction: 4 1/5 = (4 * 5 + 1)/5 = 21/5. Next, we multiply by 7: (21/5) * 7 = 21 * 7 / 5 = 147/5 inches. To convert it to a mixed number, we divide 147 by 5 which equals 29 with a remainder of 2, leading to a mixed number of 29 2/5 inches. Thus, the enlarged picture has a length of 29 2/5 inches.
