<span>let: m1 = 2xy a m2 = 2xy b m3 = 2x2y c since 2 and 3 have a common factor let b=2n m1 = 2xy a m2 = 2xy 2 n m3 = 2x2y c or simply m1 = 2xy a m2 = 2xy 2n m3 = 2xy 2c given that anc have no common factors</span>

Solve the trigonometric equation √2 cos − 1 2 cos + 1 = 0 in the interval [0, 360°). find the exact values of the solutions in d
Elena-2011 [213]
Assuming cos means cos(x); 

Combine all like terms: cos(x)(√2 - 12)= -1 
Isolate x: cos(x)= -1/(√2 - 12) 

cos(x)=0.0944 
x=cos⁻¹(0.0944) 
x= 84.57 degrees or (360-x=275.42 degrees) 

Hope I helped :)

A roll of carpet that contains 250 yd of carpet will cover how many rooms if each room requires 7 3/4 yards of carpet?
iren [92.7K]

Answer: 32 room

Step-by-step explanation:

7\frac{3}{4} =\frac{4(7)+3}{4} =\frac{28+3}{4} =\frac{31}{4}=7.75

<u>If 1 room = 7.75 yd of carpet ⇒ x rooms = 250 yd of carpet</u>

Use proportions & cross-multiply to solve:

\frac{1}{7.75} =\frac{x}{250}\\7.75x=250\\x=\frac{250}{7.75} =32.258

So 250 yd of carpet can cover about 32 rooms.

On May 1, Cleveland Livingston opened a savings account that paid
Ludmilka [50]

Answer:

Step-by-step explanation:

rate  = 3.5% per month

A) Six  days later the bank calculated the daily interest.

so, time = 6 days

= 6 / 30 = 1/5 month

simple interest  =\frac{P*r*t}{100}

=\frac{5000*3.5*1/5}{100} \\\\=35

=35%

B) For $5000, t = 1 month

For $2000, t = 20 / 30 = 2/3 month

For $8000, t = 16/30 months

Simple interest for $5000

=\frac{500083.5*1}{100} \\\\= 175

$175

Simple interest for $2000

=\frac{2000*3.5*2/3}{100} \\\\=\ 46.67

=$46.67

Simple interest for $8000

=\frac{8000*3.5*16/30}{100} \\\\=149.33

=$149.33

Total amount in account at the end of 30 days is

= $5000 + $175 + $2000 + $46.67 + $8000 + $149.33

= $15371
