Answer:

The ratio of the number of gigabytes to the price in dollars for Dial It Up is 1:8

The ratio of the number of gigabytes to the price in dollars for Ring Ring is 1:9

Step-by-step explanation:

The word problem relates to the comparison between the cost of a gigabyte on Dial It Up network and the cost per gigabyte on Ring Ring network

On Dial It Up, 2 gigabytes costs $16

Therefore, 1 gigabytes costs $16/2 = $8

Which gives Dial It Up cost per gigabyte as $8 per gigabyte

On Ring Ring, 1 gigabytes costs $9

Which gives Ring Ring cost per gigabyte as $9 per gigabyte

The ratio of the number of gigabytes to the price in dollars for Dial It Up is 1:8

The ratio of the number of gigabytes to the price in dollars for Ring Ring is 1:9.

Which ordered pairs are solutions to the inequality 3x-4y>5

Sloan [31]

Note: you did not provide the answer options, so I am, in general, solving this query to solve your concept, which anyways would clear your concept.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the inequality

$3x-4y>5$

All we need is to find any random value of 'x' and then solve the inequality.

For example, putting x=3

$3\left(3\right)-4y>5$

$9-4y>5$

$-4y>-4$

$\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}$

$\left(-4y\right)\left(-1\right)$

$4y$

$\mathrm{Divide\:both\:sides\:by\:}4$

$\frac{4y}{4}$

$y$

So, at x = 3, the calculation shows that the value of y must be less

than 1 i.e. y<1 in order to be the solution.

Let us take the random y value that is less than 1.

As y=0.9 < 1

so putting y=0.9 in the inequality

$3\left(3\right)-4\left(0.9\right)$

$=9-3.6$

$=5.4$

As 5.4 > 5

Means at x=3, and y=0.9, the inequality is satisfied.

Thus, (3, 0.9) is one of the many ordered pairs solutions to the inequality 3x-4y>5.

Pyramid A is a square pyramid with a base side length of 14 inches and a height of 6 inches. Pyramid B has a volume of 3,136 cub

leonid [27]

The Volume of PYRAMID A is 8 times greater than the Volume of PYRAMID B as obtained by taking the ratio of the volume of both pyramids.

Volume of a square based pyramid is given as :

$V = a^2h/3$

Where; h = height ; a = base edge

Hence, Volume of PYRAMID A :

$V = 14^2 * (6/3)\\\\V = 392 in^3$

Volume of PYRAMID B = 3,136 in³

Divide Volume of pyramid B by pyramid A :

$3136 in^3 / 392 in^3$

= 8 times

Expressing as a percentage, multiply by 100% ;

8 * 100% = 800%

Therefore, The volume of PYRAMID B is 800% times GREATER THAN that of PYRAMID A.

If you'd graph this function, you'd see that it's positive on [-1.5,0], and that it's possible to inscribe 3 rectangles on the intervals [-1.5,-1), (-1,-0.5), (-0.5, 1].

The width of each rect. is 1/2.

The heights of the 3 inscribed rect. are {-2.25+6, -1+6, -.25+6} = {3.75,5,5.75}.

The areas of these 3 inscribed rect. are (1/2)*{3.75,5,5.75}, which come out to:

{1.875, 2.5, 2.875}

Add these three areas together; you sum will represent the approx. area under the given curve on the given interval: 1.875+2.5+2.875 = ?

Answer:

469 miles

Step-by-step explanation:

1 in = 125 miles

3.75 in =?

3.75 x 125 = 468.75 miles

468.75 rounds up to 469 miles
