HELP NEEDED!!!! MUCH APPRECIATED

We have

t_1 + t+2 = \dfrac{\sqrt{s}}{4} + \dfrac{s}{1100} = .5

Multiplying through by 1100,

275 \sqrt{s} + s = 550

275 \sqrt{s} = 550 - s

Squaring (which means we need to check later),

275^2 s = (550 - s)^2 = 550^2 - 1100 s + s^2

0 = s^2 - (1100 + 275^2) s + 550^2

0 = s^2 - 76725 s + 302500

s = \frac 1 2 (76725 \pm 1375 \sqrt{3113} )

s \approx 3.94285 \textrm{ or } s \approx 76721.0571

Clearly there's no way that giant number would work; must be extraneous.

Answer: 3.94

fill in the missing number in this newspaper report: houses cost 150.000 a year ago.they now cost is ?. this is a 25% increase w
svet-max [94.6K]

Answer: 187500

Step-by-step explanation:

Interest= principal ×rate×time/100

Let interest be I

Principal be P

Rate be r

Time be t

So we have

I=p×r×t/100

P in the question is 150000

T is 1year

R is 25%

Substitute for the values

I=150000×1×25/100

Interest= 37500

To know the exact cost now

Add the interest to the principal cost

Exact value=interest +principal

Exact value =37500+150000

Exact value=187500

The cost of the house now is=187500

Using the formula F=9/5C+32, find C when F= 75.
den301095 [7]

Answer:

DIVIDING 9 AND 5 = 23.8

9/5 FRACTION = 0.04

Step-by-step explanation:

If 9/5 means 9 divided by 5

FLIP THE EQUATION

9/5C + 32 = 75

9/5C + 32 - 32 = 75 -32

9/5C = 43

9/5 = 1.8

1.8C = 43

1.8C/1.8 = 4

If 9/5 means 9/5ths fraction

FLIP THE EQUATION

9/5C + 32 = 75

9/5C + 32 - 32 = 75 -32

9/5C = 43

9/5C / 9/5 = 43 / 9/5

C = 0.04

Hope this helps i thought 9/5 was 9 divide by 5. If it was 9/5 as a fraction i also made that equation too.
