Answer:

50% increase in weight

Step-by-step explanation:

First, write the situation out in an equation:

7/100=10.5/x

If we find the difference assuming 7 is 100% and 10.5 is x%, then we can subtract to find the difference.

Solve this equation for x. The answer would look like this:

7/100=10.5/150

Then, since 150% - 100% is 50%, the answer is a 50% increase.

Hope this helps! Please mark brainliest! :)

Answer:

If the perimeter of a square measures 32 cm, each side measures 32/4= 8 cm, because all sides are equal.
The diagonal that passes through the center of the square divides the square into two triangles. The triangles are formed by a hypotenuse (the diagonal, which is k in this case), and two sides, that measure 8 cm each, in this case.
Because of Pythagoras' theorem, we know that the lenght of the hypotenuse (in this case the hypotenuse is k) equals the squared root of the sum of the squared sides, which in this case can be expressed as $k=\sqrt{8^2+8^2} =\sqrt{64+64}=\sqrt{128}=11.31$ .
Then, k=11.31 cm.

Linda's start up cost for her online jewelery store was $250, as she has to pay an additional $60per month to keep it running. W

Goryan [66]

Total Cost = 250 + 60x is the equation that models the given situation

Solution:

Given that, Linda's start up cost for her online jewelery store was $250

She has to pay an additional $60 per month to keep it running

To find: Equation that models this situation

From given,

Start up cost = $ 250

Let "x" be the number of months she keeps the store running

Additional pay per month = $ 60

Thus, the total cost Linda spend to keep the store running is given as:

Total Cost = Startup cost + (Additional pay per month)(number of months)

$Total\ Cost = 250 + 60x$

Thus the equation that models the given situation is found

Solve 1. x2 + x - 6 = 0

ololo11 [35]

Answer:

x = -3 x=2

Step-by-step explanation:

x^2 + x - 6 = 0

Factor

What two numbers multiply to -6 and add to 1

3*-2 =-6

3+-2 =1

(x+3) (x-2) = 0

Using the zero product property

x+3 = 0 x-2 = 0

x = -3 x=2
