Beak the face into three shapes one 10x2 and then two small squares 2x2 each
20+4+4=28
Answer: Yes. The expression can be used to calculate how much Danielle has.
Step-by-step explanation:
The choir trip expenses are:
Train tickets = $77
Hotels = $106
Meals = $34
Total expense = $77 + $106 + $34 = $217
Since we are told that Danielle has a third of the amount needed for the trip. This means that we have to calculate 1/3 of $217 This will be:
= 1/3 × $217
= $72.33
Also, the expression (77+106+34) divided 3 shows the amount that Danielle has. Thus will be:
= (77+106+34) / 3
= 217/3
= 72.33
Answer:
y = 1
Step-by-step explanation:
6 = 2y + 4
6 - 4 = 2y
2 = 2y
y = 2/2
y = 1
Compensation per hour: 20,90 / 2,75 = 7,6$
In 7 1/4 hours he will make:
7,6 * 7,25 = 55,1$
Answer:
See below.
Step-by-step explanation:
When x has a value between 0 and 90 the values of sin x ranges from 0, if x = 0 and 1 , if x = 90 degrees.
The cosine of x has the reverse value: cos x is 1 for x = 0 and 0 for x = 90 degrees.
At x = 45 the sine and cosine are equal in value.
So for sin x < cos x the value of x must be between 0 and 45 degrees.
So a possible value of x is 30 degrees.
When x = 30 sin x = 0.5 and cos x = 0.866.
