murzikaleks [220]

Answer:

Step-by-step explanation:

$1,250,000 in current assets (cr) and $500,000 in current liabilities(cl)

current ratio (cr)=1250000/500000=2.5

Δ note payable ( change in note payable NP)

minimum current=2.2

2.2=(1250000+ΔNP)/(500000+ΔNP)

2.2(500000+ΔNP)=1250000+ΔNP

1100000+2.2ΔNP=1250000+ΔNP

2,2ΔNP-ΔNP=1250000-1100000

1.2ΔNP=150000

ΔNP=150000/1.2=125000

Nelson's short-term debt (notes payable) increase without pushing its current ratio below 2.2=125000

assuming this amount used to increase the inventory

new inventory=335000+125000=360000

current asset= 1250000+125000=1375000

the new ratio=(1375000-360000)/500000+125000

new ratio = 1.624

Three lengths will be a triangle only if the sum of two sides is greater than the third side.

19+11 > 17

This is a triangle.

23+28> 52\\51>52\\51 \ngtr 52

This is not a triangle.

9+25> 34\\34>34\\34\ngtr 34

Grace bought a television for $329 and some DVDs for $5.75 each. Write and equations to find out how many DVDs grace bought if s
marishachu [46]

The total number of DVDs that she bough is 6

<h3>Linear equations</h3>

Linear equation are expression that has a leading degree of 1.

Let the price of each DVD be x such that if Grace bought a television for $329 and some DVDs for $5.75 each  and spent a total of $363.50, ten;

329 + 5.75x = 363.5

Subtract 329 from both sides

329 + 5.75x - 329 = 363.5 - 329

5.75x = 34.5

x = 34.5/5.75

x = 6

This shows that the total number of DVDs that she bough is 6

Find the value of each variable in the parallelogram
wlad13 [49]

Answer:

B= 90

C= 80

D= 100

Step-by-step explanation:

So let’s start with the bottom angles.

We know that the adjacent angles in a parallelogram add up to 180° so our equation would be (b-10) + (b+10)=180. So let’s simplify it b and b are both the same variables so we will get 2b and -10 + 10 is 0 so we get the following equation 2b=180.

So now we divide 180 and 2 and we get 90 as b.

So one side will be 100 because of the +10 and the other 90 because of the -10.

Now for the next side.

d+c=180

So we know that b+10 is adjacent to c so 180-100 is 80, so 80 is c.

Now for d.

b-10 is 80 so 180-80 is 100, so d is 100.
