Two lines intersect. Find the value of b and c.

42°

Answers

Answer:

b=42 degrees

c= 138 degrees

Step-by-step explanation:

B and the 42 degrees shown are congruent angles so therefore both are 42 degrees

To find C: We know that combining the 42 degrees and Angle C would form a flat angle or 180 degree angle, so therefore

subtract 180 with 42 to get Angle C

180-42= 138

Answer:

b=42, c=138

Step-by-step explanation:

B has to equal 42 because b is opposite of the 42º

and since 42+2c+42 has to equal 360, we simplify the expression to get:

84+2c=360,

2c=276

c=138

Alana is cooking a turkey. It takes 4 1/2 h to cook. She checks it every 20 min, or 1/3 h.
How many times will she check it before it is cooked?​

Answers

Answer:

13 times

Step-by-step explanation:

There are a total of 270 minutes in 4 1/2 hours.

270 ÷ 20 = 13.5

Though we know that 13.5 would not work out.

So she would check on it 13 times.

After the 13th time there will be 10 minutes left to cook the turkey.

The total number of times Alana will check the turkey before it sis done is 13 times.

Rate of work

The rate at which Alana is checking the turkey can be described as the work rate or the rate at which she is doing work.

Number of times

The total number of times at which Alana will check the turkey before it is done is calculated as follows;

[tex]n = \frac{T}{R}[/tex]

where;

T is the total time = 4 1/2 h = (4 x 60) + 30 min = 270 min

R is the rate = 20 min

[tex]n = \frac{270}{20} \\\\n = 13.5 \ times\\\\n \approx 13 \ times[/tex]

There is no half checking, thus, the total number of times Alana will check the turkey before it sis done is 13 times.

Equation: y = 2.5x

Answer: 43.75 drawers

Step-by-step explanation:

Equation: 10 - 7.5 = 2.5 and when you subtract 2.5 until the Number of Drawers (x) is 0, then you get 0 for Total Volume (y), so y =2.5x+0 or y = 2.5x

Answer: Substitute 17.5 into x.

y = 2.5(17.5)

y = 43.75 drawers
