A) The Girth is calculated as; 45.625 inches

B) The calculated girth is greater than the maximum of 45 inches and as such we will conclude that we will not be able to store the suitcase in the overhead compartment.

<h3>How to use basic math's operations?</h3>

We want to find the girth of a suitcase.

Now, we are told that the formula to calculate the girth of a suitcase is;

Girth = Length + Width + Depth

A) We are given;

Length of Suitcase = 24.5 inches

Width of suitcase = 14.25 inches

Depth of Suitcase = 6.875 inches

Thus;

Girth = 24.5 + 14.25 + 6.875

Girth = 45.625 inches

B) We are told that in order for us to use the suitcase in the overhead compartment, that the girth must not exceed 45 inches.

Now, our calculated girth is greater than the maximum of 45 inches and as such we will conclude that we will not be able to store the suitcase in the overhead compartment.

Graph the following lines and using the graph determine several values of x for which the graph is positive (negative): y=−4x+3

True [87]

Answer:

Step-by-step explanation:

Given line is,

y=-4x+3

when, x=-1 , y=-4(-1)+3=4+3=7

when, x=0 , y=-4(0)+3=0+3=3

when, x=1 , y=-4(1)+3=-4+3=-1

So, we got the points (-1,7) , (0,3) , (1,-1)

Now, putting the points in the graph and adding them , we will get the graph of given line.

Please check image for the graph.

Now for the second part-

The graph is positive means- it will be above the x-axis, that is y value will be positive.

From the graph we can see that, if x<0 , then y is positive.

So, any value of x which is less than 0 , will give the positive graph here.

Answer:

$y > \boxed{\cfrac{42}{5} }$

Step-by-step explanation:

Given inequality:

$\cfrac{y}{3} > 7 - \cfrac{y}{2}$

To solve for y.

Solution:

Rewrite the inequality as,

$\displaystyle \frac{1y}{3} > \frac{ - 1}{2} y + 7$

Adding 1/2y to both sides,

$\cfrac{1}{3} y + \cfrac{ 1 }{2} y > \cfrac{ - 1}{2}y + 7 + \cfrac{1}{2} y$

$\cfrac{5}{6} y > 7$

Multiplying both sides by 6/5:

$\cfrac{6}{5} \times \cfrac{5}{6} y > \cfrac{6}{5} \times 7$

$y > \boxed{\cfrac{42}{5} }$

Value of y is 42/5.

For her phone service, Rita pays a monthly fee of $17, and she pays an additional $0.05 per minute of use. The least she has bee

Alona [7]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Monthly fee = $17

Additional fee per unit of use = $0.05

Least amount she's been charged in a month = $83.90

Equation to represent the number of minutes 'M':

monthly fee + (additional fee per minute × M) = $83.90

Possible number of minutes :

83.90 ≤ $17 + 0.05M

$17 + $0.05 × M = $83.90

$0.05*M = $83.90 - $17

$0.05*M = $66.90

M = $66.90 / 0.05

M = 1,338 minutes

Let v be the volume of a sphere, s be the surface area of the sphere, and r be the radius of the sphere. which equation represen

MakcuM [25]

Let
v-------> the volume of a sphere
s-------> the surface area of the sphere
r------> the radius of the sphere

we know that
v=(4/3)*pi*r³-----> v=(r/3)*4*pi*r²------> equation 1
and
S=4*pi*r²-----> equation 2

substitute equation 2 in equation 1
so
v=(r/3)*4*pi*r²-------> v=(r/3)*s

the answer is
the equation that represents the relationship between these three measures
 v=(r/3)*s
