This trapezoid-based right pyramid has a volume of 48 m3 what is the area?

Answer: 10%

Step-by-step explanation:

Since the shopkeeper purchased 60 pencil boxes for 4,500, he purchased them at the rate of:

= 4500 / 60

= 85 per pencil box

If the shopkeeper sold them at the rate of 4,125 for 50 pencil boxes, then he sold them at the rate of:

= 4125 / 50

= 82.50 per pencil box.

Therefore the percentage profit will be:

= Gain / Cost price × 100

= (82.50 - 75) / 75 × 100

= 7.5/75 × 100

= 10%

I would maybe say 34% im in sixth grade and this hard for me atleast i tried

Answer:

1 out of 27,636,336,000

Step-by-step explanation:

40 · 39 · 38 · 37 · 36 · 35 = 27,636,336,000

Answer:

Answer B.

Because we know He's checking the experiment every 5 minutes.

Answer: B. 183 cm^3

V = pi r^2 h/3

V = pi (5^2) (7/3)

V = pi (25) (2.33)

V = 183

Answer:

B.183 [tex]cm^{3}[/tex]

Step-by-step explanation:

Volume of cone is [tex]V=\pi r^{2} \frac{h}{3}[/tex]

where h=7 and r=5 (because r=d/2, where d=10)

V=[tex]5^{2}\frac{7}{3}\pi[/tex]

V=25·[tex]\frac{7}{3} \pi[/tex]

V=175/3[tex]\pi[/tex]

V=183.2595715 or 183 [tex]cm^{3}[/tex]

Given:

The figure of a triangle.

To find:

The missing length.

Solution:

Let x be the missing length.

Basic proportionality theorem(BPT): According to this theorem, if a line is parallel to the one side of a triangle then that the line intersects the other two sides of the triangle in the same ratio.

Using Basic proportionality theorem, we get

[tex]\dfrac{6}{8-6}=\dfrac{12-x}{x}[/tex]

[tex]\dfrac{6}{2}=\dfrac{12-x}{x}[/tex]

[tex]3=\dfrac{12-x}{x}[/tex]

[tex]3x=12-x[/tex]

Adding x on both sides, we get

[tex]3x+x=12[/tex]

[tex]4x=12[/tex]

[tex]x=\dfrac{12}{4}[/tex]

[tex]x=3[/tex]

The missing length is 3 Therefore, the correct option is D.

Answer:

[tex]f^{-1}(6) = 50[/tex]

Step-by-step explanation:

Given

[tex]f(x) = \sqrt{2x} - 4[/tex]

Required

Find [tex]f^{-1}(6)[/tex]

First, we calculate the inverse function

[tex]f(x) = \sqrt{2x} - 4[/tex]

Express f(x) as y

[tex]y = \sqrt{2x} - 4[/tex]

Swap the positions of x and y

[tex]x = \sqrt{2y} - 4[/tex]

Solve for y: Add 4 to both sides

[tex]4 + x = \sqrt{2y} - 4+4[/tex]

[tex]4 + x = \sqrt{2y}[/tex]

Square both sides

[tex](4 + x)^2 = 2y[/tex]

Divide both sides by 2

[tex]y = \frac{(4 + x)^2}{2}[/tex]

Express y as an inverse function

[tex]f^{-1}(x) = \frac{(4 + x)^2}{2}[/tex]

Next, solve for: [tex]f^{-1}(6)[/tex]

Substitute 6 for x

[tex]f^{-1}(6) = \frac{(4 + 6)^2}{2}[/tex]

[tex]f^{-1}(6) = \frac{(10)^2}{2}[/tex]

[tex]f^{-1}(6) = \frac{100}{2}[/tex]

[tex]f^{-1}(6) = 50[/tex]

Answer: B

Step-by-step explanation: So that you know you are only getting the best for what YOU PAID for.

Yes I think you are correct. The domain appears to be the set of x values such that -4 < x < 3 meaning that x is between -4 and 3, excluding each endpoint. In interval notation, that translates to (-4, 3). This of course assumes that we have two vertical asymptotes bookending the left and right sides of the curve, and these vertical asymptotes are at x = -4 and x = 3. If the curve extends beyond these boundaries, then the domain would instead be the set of all real numbers.

Answer:

Harper's age = 18

Miguel age = 16

Step-by-step explanation:

Given:

Miguel age = [2/3][Harper's age] + 4

Sum of their age = 34

Computation:

Assume;

Harper's age = a

So,

Miguel age = [2/3][a] + 4

Sum of their age = 34

So,

Miguel age + Harper's age = 34

[2/3][a] + 4 + a = 34

[2a / 3] + a = 34 - 4

[2a + 3a] / 3 = 30

5a / 3 = 30

5a = 90

a = 18

So,

Harper's age = 18

Miguel age = [2/3][a] + 4

Miguel age = 16

Use the binomial theorem:

[tex]\displaystyle (2x-9)^5 = \sum_{k=0}^5 \binom5k (2x)^{5-k}(-9)^k = \sum_{k=0}^5 \frac{5!}{k!(5-k)!} 2^5 \left(-\frac92\right)^k x^{5-k}[/tex]

The x ³ terms occurs for 5 - k = 3, or k = 2, and its coefficient would be

[tex]\dfrac{5!}{2!(5-2)!} 2^5 \left(-\dfrac92\right)^2 = \boxed{6480}[/tex]

Answer:

[tex](-2,8)[/tex]    [tex](7,5)[/tex]      [tex](1,7)[/tex]

Step-by-step explanation:

Given

[tex]x + 3y = 22[/tex]

Solving (a): The possible coordinates

We have:

[tex](x,y) = (-2,8)[/tex]

This gives:

[tex]x + 3y = 22 \to -2 + 3 * 8[/tex]

[tex]x + 3y = 22 \to -2 + 24[/tex]

[tex]x + 3y = 22 \to 22[/tex]

(-2,8) is a point on the grid

[tex](x,y) = (7,5)[/tex]

This gives:

[tex]x + 3y = 22 \to 7 + 3 * 5[/tex]

[tex]x + 3y = 22 \to 7 + 15[/tex]

[tex]x + 3y = 22 \to 22[/tex]

(7,5) is a point on the grid

[tex](x,y) = (-5,5)[/tex]

This gives:

[tex]x + 3y = 22 \to -5 + 3 * 5[/tex]

[tex]x + 3y = 22 \to -5 + 15[/tex]

[tex]x + 3y = 22 \to 10[/tex]

(-5,5) is a not point on the grid

[tex](x,y) = (1,3)[/tex]

This gives:

[tex]x + 3y = 22 \to 1 + 3 * 3[/tex]

[tex]x + 3y = 22 \to 1 + 9[/tex]

[tex]x + 3y = 22 \to 10[/tex]

(1,3) is a not point on the grid

[tex](x,y) = (1,7)[/tex]

This gives:

[tex]x + 3y = 22 \to 1 + 3 * 7[/tex]

[tex]x + 3y = 22 \to 1 + 21[/tex]

[tex]x + 3y = 22 \to 22[/tex]

(1,7) is a point on the grid

So, we plot the following on the grid

[tex](-2,8)[/tex]    [tex](7,5)[/tex]      [tex](1,7)[/tex]

The speed of light (c) is considered a fundamental constant of nature. In the famous relativity equation, E = mc², the speed of light (c) serves as a constant of proportionality, linking the formerly disparate concepts of mass (m) and energy (E).

Answer:

(2,14)

Step-by-step explanation:

Since y=5x+4, you can plug that into the other y in the other equation which would give you x+12=5x+4

Now subtract 12 from both sides

x=5x-8

Subtract 5x from both sides

-4x=-8

Now you divide them both by -4 which gives you x=2

Now plug x in to any of the equations

y=5(2)+4

y=10+4

y=14

Your final answer is (2,14)

Given:

The point (5,-2) is translated 3 units to the left.

To find:

The new location of the point.

Solution:

If a point is translated 3 units to the left, then

[tex](x,y)\to (x-3,y)[/tex]

Using this rule of translation, we get

[tex](5,-2)\to (5-3,-2)[/tex]

[tex](5,-2)\to (2,-2)[/tex]

Therefore, the new location of the point is (2,-2). Hence, the correct option is C.
