Answer:

A. 384 cm3

Step-by-step explanation:

I took the quiz

v = 1/3 x area of base x height

volume = 1/3 x (12 x 12) x 8

= 384 cm3

this is the square pyramid you're talking about?

Answer:

c = 8

Step-by-step explanation:

x = 6

from first equation : 6 + 4y = 2 → 4y = 2-6=-4 → y= -1

second equation : 6 -2(-1) = c → c = 6+2=8

Answer:

1

Step-by-step explanation:

Mistake in the second step.

We must add positive numbers or negative ones.

Here he had add the positive and negative numbers and that is the mistake

[tex]=3-(-5)-7\\\\=3+5-7[/tex]Here 5 is positive because -×-=+

[tex]=8-7[/tex]

[tex]=1[/tex]

In the second step, we must add the positives that are 3 and 5 and subtract from 7.

Hope it will help you.

We know that:

The expected number of times he picks a blue marble is the mean of the blue marbles

Malik should expect to pick a blue marble 10 times when he picks 25 marbles

The given parameters are:

Blue = 16

Red = 12

Green = 12

The total number of marbles is:

Total = 16 + 12 + 12

So, we have:

Total = 40

When he picks 25 marbles, the expected number of blue marble is:

Expected = Blue/Total * 25

So, we have:

Expected = 16/40 * 25

Evaluate the product

Expected = 10

Hence, he should expect to pick a blue marble 10 times when he picks 25 marbles

Answer:

  (1/2)^(t/4) = ((1/2)^(1/4))^t

Step-by-step explanation:

If time t is given in hours, then the number of 4-hour time periods is t/4. If the half-life is 4 hours, the population multiplier is ...

  (1/2)^(t/4)

Using the rules of exponents, that can be rearranged to ...

  (1/2)^((1/4)·t) = ((1/2)^(1/4))^t

That is, the multiplier every hour is ...

  (1/2)^(1/4)

Step-by-step explanation:

First we need to find the total of the fruit

7+5+8 = 20

The fraction of the fruit that is mangoes is the number of mangoes over the total.

mangoes / total = 5/20 = 1/4

=======================================================

Explanation:

Line K is 9x-4y=-5*4 which is the same as 9x-4y=-20

Rule: Anything parallel to Ax+By = C is of the form Ax+By = D.

The equation 9x-4y=-20 has A = 9, B = -4 and C = -20.

That means Ax+By = D becomes 9x-4y = D.

------------------------------

Plug in the coordinates (x,y) = (4,7) and compute the value of D.

9x-4y = D

D = 9x-4y

D = 9(4)-4(7)

D = 36 - 28

D = 8

So 9x-4y = D becomes 9x-4y = 8

----------------------------

The last step is to solve for y to get the equation in y = mx+b form.

9x-4y = 8

-4y = 8-9x

-4y = -9x+8

y = (-9x+8)/(-4)

y = (-9x)/(-4) + 8/(-4)

y = (9/4)x - 2    is the slope-intercept form of line L

The equation is in y = mx+b form where,

m = 9/4 = slope

b = -2 = y intercept

1. K(x) = (3x)2 -x + 2 -x + 1

k(x) = g(x) ∘ h(x)

2. K(x) = 2 ^3x + 2

k(x) = g(x) × h(x)

3. K(x) = 2^x - 3x - 2

k(x) = h(x) ÷ g(x))

4. K(x) = 3(2 x) + 2

k(x) = h(x) ∘ g(x)

5. K(x) = 2^x + 3x + 2

k(x) = g(x) - h(x)

6. K(x) = 2^x(3x + 2)

k(x) = g(x) + h(x)

8 books per box

Step-by-step explanation:

one box can hold 8 books

By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is                    [tex]\sum_{n=4}^{15} 5(-2)^{n-1}$$[/tex]  

Sequence is collection of  numbers with some pattern .

Given sequence

[tex]a_{1}=5\\\\a_{2}=-10\\\\\\a_{3}=20[/tex]

We can see that

[tex]\frac{a_1}{a_2}=\frac{-10}{5}=-2\\[/tex]

and

[tex]\frac{a_2}{a_3}=\frac{20}{-10}=-2\\[/tex]

Hence we can say that given sequence is Geometric progression whose first term is 5 and common ratio is -2

Now [tex]n^{th}[/tex]  term of this Geometric progression can be written as

[tex]T_{n}= 5\times(-2)^{n-1}[/tex]

So summation of 15 terms can be written as

[tex]\sum_{n=4}^{15} T_{n}\\\\$\\$\sum_{n=4}^{15} 5(-2)^{n-1}$$[/tex]

By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is                    [tex]\sum_{n=4}^{15} 5(-2)^{n-1}$$[/tex]

Answer: There are two ways you can do this; by radians or by degrees.

Step-by-step explanation: The formula used for calculating an area of a circle's shaded region in RADIANS is: A = (θ / 2) × r^2 and θ is equivalent to radians. The second formula used for calculating an area of a circle's shaded region in DEGREES is: (θ / 360) × πr2 where θ is equivalent to degrees.

We know that, 1 litre = 1000 ml

Then, 2 litres = 2000 ml

Hence, the required ratio of 1000 ml to 2000 ml be

= 1000 : 2000

= 1 : 2

1 litres =1000ml

then

1000:2000

x = 30

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180

The given is a right triangle so one of the angle is 90 degrees:

90 + 2x + x = 180 add like terms

90 + 3x = 180 subtract 90 from both sides

3x = 90 divide both sides by 3

x = 30
