A student earns $7.50 per hour at her part-time job. She wants to earn at least $200.Enter an inequality that represents all of the possible numbers of hours (h) the student could work to meet her goal.
Enter the least whole number of hours the student needs to work in order to earn at least $200
Answers
Answer: 7.50 h ≥200
She needs to work 27 hours to earn at least $200.
Step-by-step explanation:
Hi, to write the inequality we have to analyze the information given:
- Earnings per hour : $7.50
- Hours : h
- She wants to earn at least $200.
So, she earns $7.50 per hour, the expression that represents the statement is $7.50h.
She wants to earn at least $200, "at least" means more or equal (≥200).
Mathematically speaking:
- $7.50 h ≥200
This is the inequality that represents all of the possible numbers of hours (h) the student could work to meet her goal.
For the second part we simply solve the inequation:
7.50 h ≥200
h ≥200/7.50
h ≥ 26.67
Rounded to the nearest whole number:
h ≥ 27
She needs to work 27 hours to earn at least $200.
7.5h≤200
thus
h≤80/3
writing in whole numbers we shall have:
h≤27

Answer:
The probability that Emma has heart disease and the test predicts heart disease is:
48%
Step-by-step explanation:
Let A denote the event that Emma has a heart disease.
and B denote the event that the test predicts accurate.
Hence, A∩B denote the event that Emma has heart disease and the test predicts heart disease.
From the given equation we have:
P(A)=0.6
and P(B)=80%=0.8
As we know that event A and event B are independent.
Hence, we have:
P(A∩B)=P(A)×P(B)
⇒ P(A∩B)=0.6×0.8
⇒ P(A∩B)=0.48=48%
Hence, the probability is:
48%

Answer:
8 = 2^3
Step-by-step explanation:
8 = 4*2
4 is not a prime number so we break 4 into 2*2 and replace it
8 = 2*2*2
All of these are prime
We see there are three 2's multiplied together, that means 2 is the base and 3 is the exponent
8 = 2^3
2^3 is index form

sin 45=opposite side/hypotenuse
opposite side=7√2
hypotenuse=x
sin 45=7√2/x--------> x=7√2/sin 45
sin 45=√2/2
so
x=7√2/(√2/2)-----> x=(7√2*2)/√2-----> x=14
the answer is
the value of x is 14
The value of x in the figure would be 14. Option 3.
Trigonometry problem
To get x, we can use the following formula:
Sine 45 = opposite/hypotenuse
In this case:
opposite = 7√2
hypotenuse = x
Thus:
Sine 45 = 7√2/x
x = 7√2/sine 45
= 7√2/√2/2
= 7√2 x 2/√2
= 14
In other words, the value of x is 14.
