2. A coin purse contains d dimes and q quarters. There are 20 coins in the purse, and the total value of the coins is $4.25. Which system of equations represents this situation?
A {d + q = 4.25
{0.1d + 0.25q = 20

B {d + q = 20
{0.1d + 0.25q = 4.25

C {d + q = 20
{d + q = 4.25

Answers

Answer 1
B. D represents the amount of dimes and q represents the amount of quarters so that equals 20 coins total. 0.25q is the amount of quarters multiples by their cost, when added to 0.1d it equals 4.25.

Find the value of x in 2x – 13 = 5 ​

Answers

Answer:

x=9

Step-by-step explanation:

So first, you have to add 13 to both sides to isolate the x so that will make the equation 2x=5+13. Add 5 and 13 to get 18. The equation will now be 2x=18. Divide both sides by 2 because we want x to equal one. This will make it x=18/2. Simplify that and get x=9

Hope this helps

On Monday, a local hamburger shop sold a combined total of 352 hamburgers and cheeseburgers. The number of cheeseburgers
sold was three times the number of hamburgers sold. How many hamburgers were sold on Monday?

Answers

To answer this question, you could use algebra.

If the number of cheeseburgers was three times the number of hamburgers, we could write this as.

Cheeseburgers= 3x and Hamburgers = x

We can then write an expression for the total number of burgers.

4x = 352

Divide both sides by four.

x = 88

Because hamburgers = x in relation to the cheeseburgers, that would mean the number of hamburgers sold on monday was 88.

Ken is going to throw a biased dice once.

The probability that the dice will land on six is 0.3

(b) What is the probability that the dice will not land on six?

Answers

Answer:

0.7

Step-by-step explanation:

Given a biased dice :

Probability of landing on 6 = P(6) ;

P(6) = 0.3

Recall :

P(A') = 1 - P(A)

Therefore,

If

P(6) = 0.3

P(not landing on 6) ; P(not 6) ;

P(not 6) = 1 - P(6)

P(not 6) = 1 - 0.3 = 0.7

Hence, Probability of not landing on 6 = 0.7

The vortex shedding produced by a particular object is to be studied in a water tunnel at a 1/4 scale model (model 1/4 the size of the prototype). After a dimensional study, it is found that the Pi terms of this phenomenon are the Reynolds number and the Strouhal number:Re = pVd/muSt = fd/Vwhere f is the frequency of the vortex shedding, V the velocity of the flow, d the characteristic length of the object, and p and mu the density and viscosity of the flow. 1.
