Answer:

m = 8.51

n = 5.25

Step-by-step explanation:

sin (45) = opp/hyp

sin(45) = m/10

m = 10sin(45)

m = 8.51

cos(45) = adj/hyp

cos(45) = n/10

10cos(45) = n

n = 5.25

3. Jordan cooked a 16 1/5 pound turkey in 5 2/5 hours. How many minutes per

s344n2d4d5 [400]

Answer:

20 minutes per pound

Step-by-step explanation:

we know that

To find the unit rate divide the total time by the total weight

Convert mixed number to an improper fraction

$16\frac{1}{5}\ lb=\frac{16*5+1}{5}=\frac{81}{5}\ lb$

$5\frac{2}{5}\ lb=\frac{5*5+2}{5}=\frac{27}{5}\ h$

Convert hours to minutes

$1\ h=60\ min$

$\frac{27}{5}\ h=\frac{27}{5}(60)=324\ min$

Find the unit rate

$\frac{324}{\frac{81}{5}}=\frac{1,620}{81}=20\ \frac{min}{lb}$

therefore

20 minutes per pound

Clare was solving an equation, but when she checked her answer she saw her solution was incorrect. She knows she made a mistake,

Sholpan [36]

Answer:

12 times 5=60 not 70

Step-by-step explanation:

12(5+2y)=4y-(5-9y

60+24y=4y-5-9y

60+24y=-5y-5

29y+60=-5

29y=-65

y=-65/29 or y= about -2.38

Which number produces an irrational number when multiplied by 1/2

Ludmilka [50]

Quick answer

Any irrational number. I can't think of any exception to this statement.

sqrt(5) is irrational. 1/2 * sqrt(5) is still irrational.

-sqrt(5) is irrational. -1/2 * sqrt(5) is still irrational

2 + sqrt(5) is irrational. Multiplying this by 1/2 is still irrational.

1/2(2 + sqrt(5) = 1 + 1/2 * sqrt(5) ) is irrational.

Conclusion

There are no exceptions to this. All irrational numbers produce irrationals when multiplied by 1/2
