Whats double of 8x4?
Answer:
64
Step-by-step explanation:
cus 8 times 4 is 32 and 32 times 2 is 64
The double of 8 multiplied by 4 is 64. This means that if we multiply 8 by 4 and then multiply the result by 2, we obtain 64. The multiplication operation is performed first (8 * 4 = 32), and then the result is doubled by multiplying it by 2 (2 * 32 = 64).
To find the double of 8 multiplied by 4, we can perform the following calculation:
Double of 8x4 = 2 * (8 * 4)
First, we multiply 8 and 4:
8 * 4 = 32
Next, we multiply the result by 2:
2 * 32 = 64
Therefore, the double of 8 multiplied by 4 is 64. This means that if we multiply 8 by 4 and then multiply the result by 2, we obtain 64. The multiplication operation is performed first (8 * 4 = 32), and then the result is doubled by multiplying it by 2 (2 * 32 = 64).

Which of the following arithmetic sequences have a common difference of 2 1/2
Answer: -4,-1.5,1,3.5,6,8.5
Step-by-step explanation: You can check that the difference of any of its consecutive terms is always equal to 2.5.
8.5 - 6 = 2.5
-1.5 - (- 4) = 2.5
3.5 - 1 = 2.5

Answer:
-4/3 m/s
Step-by-step explanation:
Using Pythagoras :
a² = x² + c²
5² = x² + y² - - - (1)
The horizontal distance x with respect to time t = 1m/sec
dx/dt = 1m/sec
To obtain the vertical height 'y' with respect to time t when x = 4
5² = x² + y²
Wen x = 4
5² = 4² + y²
25 = 16 + y²
y =√(25 - 16)
y = 3
Differentiate (1) with respect to t
x² + y² = 25 - ---- - (1)
2x * dx /dt + 2y dy/dt = 0
dx/dt = 1
x = 4.
y = 3
2(4)(1) + 2(3) * dy/dt = 0
8 + 6dy/dt = 0
6 dy/dt = - 8
dy/dt = - 8/6
dy/dt = - 4/3

parentheses- 4 to the 2nd power is 16, 16 + 7 is 23.
exponents- 2 to the 3rd power is 8.
multiplication- 6 x 8 is 48
so then its easy from there. its 48 minus 23, which equals 25
Each square has a side length of 12 units. Compare the areas of the shaded regions in the 3 figures. Which figure has the largest shaded region? Explain or show your reasoning.
Answer:They are equal
Step-by-step explanation:
they will add up they are just token apart or in pieces
Three different figures are given. The area of the shaded region of all the figures is the same.
We need to determine the highest shaded area among all.
Now, the area of the square is common to all.
Thus,
[tex]\begin{aligned}\rm{Area\;of\;square}&=12^2\\&=144 \;\rm{units^2}\end{aligned}[/tex]
1). Calculate the shaded area for figure A.
The diameter of the circle is 12 units, hence its radius is 6 units.
Therefore,
[tex]\begin{aligned}\rm{Area\;of\;circle}&=\pi \times 6^2\\&=36 \pi \;\rm{units^2}\end{aligned}[/tex]
[tex]\begin{aligned} \rm{Shaded\; area} &= \rm{Area\; of\; the\; square - Area\; of\; the\; circle}\\&=144-36 \pi \end{aligned}[/tex]
Thus, the area of the shaded region for figure 1 is [tex]114-36 \pi[/tex].
2). Calculate the shaded area for the figure B.
The diameter of the circle is 6 units, hence its radius is 3 units.
Therefore,
[tex]\begin{aligned}\rm{Area\;of\;circle}&=\pi \times 3^2\\&=9 \pi \;\rm{units^2}\end{aligned}[/tex]
[tex]\begin{aligned} \rm{Shaded\; area} &= \rm{Area\; of\; the\; square - 4 \times Area\; of\; the\; circle}\\&=144-36 \pi \end{aligned}[/tex]
Thus, the area of the shaded region for figure 2 is [tex]114-36 \pi[/tex].
3). Calculate the shaded area for figure C.
The diameter of the circle is 4 units, hence its radius is 2 units.
Therefore,
[tex]\begin{aligned}\rm{Area\;of\;circle}&=\pi \times 2^2\\&=4 \pi \;\rm{units^2}\end{aligned}[/tex]
[tex]\begin{aligned} \rm{Shaded\; area} &= \rm{Area\; of\; the\; square - Area\; of\; the\; circle}\\&=144-36 \pi \end{aligned}[/tex]
Thus, the area of the shaded region for figure 3 is [tex]114-36 \pi[/tex].
Therefore, the area of the shaded region of all the figures is the same.

Each school year, the seventh graders who study Life Science participate in a special field trip to the city zoo. In 2010, the school paid $1,260 for 84 students to enter the zoo. In 2011, the school paid $1,050 for 70 students to enter the zoo. In 2012, the school paid $1,395 for 93 students to enter the zoo. A. Is the price the school pays each year in entrance fees proportional to the number of students entering the zoo? Explain why or why not.
Answer:
The price is proportional to number of students
Step-by-step explanation:
Given
2010: $1260 for 84 students
2011: $1050 for 70 students
2012: $1395 for 93 students
Required
Determine if the price is proportional to number of students
To do this, we simply divide the price by number of students in each year.
[tex]Ratio = \frac{Price}{Students}[/tex]
In 2010
[tex]Ratio = \frac{\$1260}{84}[/tex]
[tex]Ratio = 15[/tex]
In 2011
[tex]Ratio = \frac{1050}{70}[/tex]
[tex]Ratio = 15[/tex]
In 2012:
[tex]Ratio = \frac{1395}{93}[/tex]
[tex]Ratio = 15[/tex]
Notice that the ratio in the 3 years is 15.
Hence, the price is proportional to number of students
