N is an integer with -5 &lt; 2n &lt;6<br> write down all the values of n?
Alika [10]

Answer:

The values of n are less than 3 and more than (-5/2)

Step-by-step explanation:

The given inequality is :

-5 < 2n <6

We need to write the values of n.

Dividing both sides of the inequality by 2. So,

\dfrac{ -5}{2} < \dfrac{2n}{2}

So, the values of n are less than 3 and more than (-5/2).

Explain how to solve the equation 2(4x-11) +9=19
xxMikexx [17]
X=4, first you distribute the 2 to both 4x and -11 which leaves you with 8x-22+9=19 next you add -22 with 9 which leaves you -13 the eqation now at 8x-13=19 so now you add 13 to both sides now youre left with 8x=32. Now the last step is to divide 8 on both sides. so that gives you the answer or X=4

\bf \begin{cases}&#10;f(x)=x^2+3\\\\&#10;g(x)=x+\cfrac{4}{3}&#10;\end{cases}&#10;\\\\\\&#10;\boxed{x=2}\qquad g(2)=(2)+\cfrac{4}{3}\implies \boxed{g(2)=\cfrac{10}{3}}&#10;\\\\\\&#10;f(~~g(x)~~)=[g(x)]^2+3\implies f(~~g(2)~~)=[g(2)]^2+3&#10;\\\\\\&#10;f(~~g(2)~~)=\left[ \boxed{\frac{10}{3}} \right]^2+3\implies f(~~g(2)~~)=\cfrac{10^2}{3^2}+3&#10;\\\\\\&#10;f(~~g(2)~~)=\cfrac{100}{9}+3\implies f(~~g(2)~~)=\cfrac{100+27}{9}&#10;\\\\\\&#10;f(~~g(2)~~)=\cfrac{127}{9}

Two similar pyramids have base areas of 12.2 cm2 and 16 cm2. The surface area of the larger pyramid is 56 cm2. What is the surfa
docker41 [41]

Given =

Two similar pyramid have base area of 12.2 cm² and 16 cm².

surface area of the larger pyramid = 56 cm²

find out the surface area of the smaller pyramid

To proof =

Let us assume that the surface  area of the smaller pyramid be x.

as surface area of the larger pyramid is 56 cm²

Two similar pyramid have base area of 12.2 cm² and 16 cm².

by using ratio and proportion

we have

ratio of the base area of the pyramids : ratio of the surface area  of the pyramids

\frac{12.2}{16} : \frac{x}{56}

x = 12.2 ×56×\frac{1}{16}

by solvingthe above terms

we get

x =42.7cm²

Hence the surface area of the smaller pyramid be 42.7cm²

Hence proved
