Solve 15 3/4 ÷ 2 5/8 × 5 5/6 ÷ 8 2/5

fenix001 [56]

Answer:

4 1/6

Step-by-step explanation:

15 3/4 ÷ 2 5/8 × 5 5/6 ÷ 8 2/5

assuming this order of operations:

(15 3/4 ÷ 2 5/8) × (5 5/6 ÷ 8 2/5)

63/4 x 8/21 = 505/84 = 6

35/6 x 5/42 = 175/252

6 x 175/252 = 1050/252 = 4 42/252 = 4 1/6

zimovet [89]

The total fabric used for headband and wristband of a player was: 27.84 inches

Step-by-step explanation:

The question will be solved step by step.

So,

Total ribbon used for headbands = 883.68 inches

Total number of people for whom headbands were made = 46 players + 2 coaches = 48 inches

so the headband for one person will use fabric: $\frac{883.68}{48}\\= 18.41\ inches$

Then

Total fabric used for wristbands = 433.78 inches

Total players = 46

$Fabri\ for\ one\ player's\ wristband = \frac{433.78}{46}\\=9.43\ inches$

Total fabric for one player = 18.41 + 9.43 = 27.84 inches

Hence,

The total fabric used for headband and wristband of a player was: 27.84 inches

One root of f(x)=x^3-9x^2+26x-24 is x = 2. What are all the roots of the function? Use the Remainder Theorem.

aniked [119]

Answer:

$x=3$ or $x=4$

Step-by-step explanation:

the given function is;

$f(x)=x^3-9x^2+26x-24$

According to the rational roots theorem, the possible rational roots are;

$\pm1,\pm2\pm3,\pm4,\pm6,\pm8,\pm12,\24$ .

According to the Remainder Theorem, if $f(a)=0$ , then $x=a$ is a zero of the polynomial.

$f(3)=3^3-9(3)^2+26(3)-24$

$f(3)=27-81+78-24$

$f(3)=24-24=0$

Also,

$f(4)=4^3-9(4)^2+26(4)-24$

$f(4)=64-144+104-24$

$f(4)=64-64=0$

Therefore the other roots are;

$x=3,x=4$
