5/8 of the 64 musicians in a music contest are guitarists, some of them play jazz solos, and the rest play classical solos. the ration of the number of guitarists playing jazz solos to the total number of guitarists in the contest is 1:4. how many guitarists play classical solos in the contest

Answers

Answer 1

Answer: 32 guitarists play classic solos. 5/8 of 64 is 40 because 64 ÷ 8 = 8 and 5 groups of 8 are guitarists (5 • 8 = 40) 1:4 is 5 added up so you multiply 4 by 8 (4 • 8 = 32) and 1 by 8 to make sure it adds to 40 (32 + 8 = 40)

Identify the two whole between which the product lies 5×7/10

Answers

Answer:

The product lies between the numbers $3\ and\ 4$

Step-by-step explanation:

we have

$5*((7)/(10))$

Solve the product

$5*((7)/(10))=(35)/(10)=3.5$

we know that

$3.5<4$

$3.5>3$

therefore

the product lies between the numbers $3\ and\ 4$

3 and 4.

To identify the whole numbers between the product you multiply the two numbers and list the whole number before and after it. 5* 7/10 = 3 1/2 or 3.5 which is between the whole numbers 3 and 4.

A train travels 25 miles in 20 minutes. What is the train speed in miles per hour?

Answers

So,

The rate of the train is 25mi/20mins. We need (x)mi/hr. We can do that by multiplying by 3.

25(3) = 75

The train's speed in mph is 75 mph.

Art supplies in Washington, D.C. Cost 28. If the sales tax is 6%, what was the total cost of supplies?

Answers

If the art supplies cost $28 and the sales tax is 6%, you must find 6% of 28. To do this, you must multiply 6 by 28, and then divide by 100. The result is 1.68. Then, to find the final cost, add the 6% of 28 (which is 1.68) to the original cost, $26, which is $29.68

Sales tax is:
$28.00* (6/100)= $1.68

$28.00+ $1.68= $29.68

The total cost of supplies was $29.68.

Explanation:

To find out how many games Cy Young won per year, we need to divide the total number of games he won by the number of years he played.

Therefore, we divide 511 (the total number of games he won) by 22 (the number of years he played):

511 / 22 = 23.23

So, Cy Young won approximately 23 games per year.

If you are using algebra tiles to factor a trinomial of the form ax2 + bx + c, when would you need to bring in zero pairs? Why?

Answers

If the value of c is negative, you would need zero pairs to model the factorization of the polynomial. The x-tiles on the board determine what the constants are in the factors. The product of these constants is equal to the value of c, so you would need positive tiles on one side of the x-squared tile and negative x-tiles on the other side to have opposite signs on the constants. Opposite signs on the constants will result in a negative value for c when multiplying the factors.

When we have c in ax2 + bx + c as negative, the pairs will have to be zero to achieve the factorization of the polynomial.

What are algebra tiles?

Algebra tiles are squares that help students to develop the manipulative skills that are required in algebraic problems.

When we have c in ax2 + bx + c as negative, the pairs will have to be zero to achieve the factorization of the polynomial. The x-tiles on the board determine what the constants are in the factors. Since we need opposite signs to show the constants this will give us a negative value for c when multiplying the factors.
