31,606,577

= 30,000,000 + 1,606,577

= 30,000,000 + 1,000,000 + 606,577

30,000,000 + 1,000,000 + 600,000 + 6,577

30,000,000 + 1,000,000 + 600,000 + 6,000 + 577

= 30,000,000 + 1,000,000 + 600,000 + 6,000 + 500 + 77

= 30,000,000 + 1,000,000 + 600,000 + 6,000 + 500 + 70 + 7

Martha has $180. she needs a total of $20000 to start an account. she earns $60 per day working, of which she saves $50. which equation can she use to determine the number days,d, she needs to work to reach her goal of $20000.

Answers


180+ 50x = 20000

she has 180 dollars to start off with so you want to add that to the total cost. Then she makes 60 a day sbyt only actually saves 50 of it so +50x (thats the way i see it. The way they put it in the question is questionable. Dont know if she puts off the 50 or the 10)

The amount she started off with + how much she saves from working per day = total amount she needs

180+ 50x = 20000

If f(x)=3x+7 and g(x)=2x-5 find g(f(-3))

A. -26 B.-9 C. -1 D. 10

Answers

The value of g(f(-3)) would be -9 which is the correct answer would be an option (B).

What exactly is a function?

A function is defined as a mathematical phrase that specifies a connection between two variables in algebra.

We have been given the functions below as

f(x) = 3x + 7 and g(x) = 2x - 5

We have to determine the value of g(f(-3))

Substitute the value of f(x) = 3x + 7 in the g(x) = 2x - 5 to get g(f(x))

⇒ g(f(x)) = 2(3x + 7) - 5

Apply the distributive property of multiplication,

⇒ g(f(x)) = 6x + 14 - 5

⇒ g(f(x)) = 6x + 9

Substitute the value of x = -3 in the g(x) = 2x - 5 to get g(f(-3))

⇒  g(f(-3)) = 6(-3) + 9

⇒  g(f(-3)) = -18 + 9

⇒  g(f(-3)) = -9

Therefore, the value of g(f(-3)) would be -9.

A snack cart sells lemonade for $2 and hot dogs for &5. The vendor sold 86 items today for a total of $330. Which equation is true?

Answers

2x+5x=330. I'm pretty sure that's it but you didn't list any answer choices.
I agree as well with both these people if you had listed your options we would have probably a better chance of getting the answer right but I do belive that the equation is right

The waist to hip ratio is the ratio, commonly expressed as a decimal that has been shown to be a good predictor of possible cardiovascular problems in both men and women. If a man has a WH are greater than one, he is considered to be at high risk for cardiovascular problems. Calculate the WHR of the male with a waist measurement of 40 inches and a hip measurement of 2 inches less.

Answers

(both women and men)=2
greater than one with that substitute in this example we will us 12 bigger then 1   2+12+1=15
WHR waist measurement would be out of 40 inches it would be 20 divide by 40= 0.5 so count that to a 5 limit 
hip measurement 2 less so then you would say 20 divide by 40 minus 2= -1.5 which equals as i typed - 1.5 so - 1.5 is your in step what you do is 
step.1- find out what 2+12+1=
step.2- find the WHR waist measurement 
step.3- then divide your waist measurements
step.4 - find the hip measurement that's less then 2 and divide it to get the answer to the proublem :P
Hope i could help :)
