There are 27 more cubic inches of sand in the pyramid with the greater volume.

Explanation:
Volume of first pyramid = 1/3 x 11 x 11 x 9 = 363 in3
Volume of second pyramid = 1/3 x 12 x 12 x 7 = 336 in3
Difference = 363 - 336 = 27 in3

Find any 6 ratinol numbers between -5/6 and 5/8​
natta225 [31]

Answer:

There is a variety of answers. you will find an example below

Step-by-step explanation:

To find the rational numbers between 2 fractions/rational numbers, we have to find the LCM of the denominator, which would increase the value of the numerator. This way you will have more rational numbers between the two.

- 5/6 = -40 / 48

5 / 8 = 30 / 48

Now, we can notice that there is a difference of 70 between the 2. this means you may choose 6 out of these. Here is an example(some of them are simplified)

5/16, 5/8, 7/48 , 1/6 , 2/6, -1/2.

Hope this helps

Two projectiles are thrown with the same initial speed, one at an angle θ with respect to the level ground and the other at angl
vichka [17]

Answer:

Height is different for both .

The time in air are different for both.

Step-by-step explanation:

Given that initial velocity is same

Lets take initial velocity = u

One at  an angle θ.

other at angle 90° − θ.

Also given that their range are same

R_1=R_2

R_1=\dfrac{u^2sin2\theta }{g}

R_2=\dfrac{u^2sin2(90-\theta)}{g}

R_2=\dfrac{u^2sin(180-2\theta)}{g}

We know that

sin(180° − θ)=sin θ

So

R_2=\dfrac{u^2sin2\theta }{g}

Height in the air

h_1=\dfrac{u^2sin^2\theta}{2g}

h_2=\dfrac{u^2sin^2(90-\theta)}{2g}

We know that

sin(90° − θ)=cos θ

h_2=\dfrac{u^2cos^2\theta}{2g}          

From above we can say that height is different for both .

Time:

T_1=\dfrac{2usin\theta}{g}

T_2=\dfrac{2usin(90-\theta)}{g}

sin(90° − θ)=cos θ

T_2=\dfrac{2ucos\theta}{g}

The time in air are different for both.

What is the solution of the inequality [3x+6]-2<10?
Ber [7]

Answer:

x > -3_2/3

Step-by-step explanation:

(3x+6)-2 < 10

Distribute  

-6x-12 < 10

    +12   +12

    -6x < 22

-6x/-6 < 22/-6

When you divide by a negative number you flip the inequality

x > 22/-6

Simplify

x > -3_2/3

Suppose that there are 11 employees in an office. The boss needs to select 5 of the employees to
sweet-ann [11.9K]

Answer:

462ways

Step-by-step explanation:

This Is a combination problem, we we are expected to determine the number of possible ways of selecting the numbers of staffs for a business trip

C(n, r) were n= 11

r=5

C(n, r) = n!/(n-r)! r!

C(n, r) = 11!/(11-5)! 5!

C(n, r) = 11!/(6)! 5!

C(n, r) = 11*10*9*8*7*6!/(6)! 5*4*3*2*1

C(n, r) = 11*10*9*8*7/5*4*3*2*1

C(n, r) = 55440/120

C(n, r) = 462

The number of possible ways is 462
