Answer:
64%.
Step-by-step explanation:
You add up all of the numbers to get all of the students, then add up the students who spend less than an hour a day. Then, you divide that number (57) by the total number (89), to get 64%.

Answer:
The area of triangle VZX is 210 cm^2
Step-by-step explanation:
Here, we want to get the measure of the area of triangle VZX
From the given diagram, we have two explicit triangles making up triangle VWX
These are triangles VWZ and VZX
By adding the areas of both triangles, we can get the area of VWX
Mathematically, the area of VZX is the difference between the area of VWX and VZW
To get the area of VZW, we can use the formula for the area of a triangle
We have this as 1/2 * base * height
base = 35 cm and height = 28 cm
The area of VWZ is 1/2 * 35 * 28 = 490 cm^2
The area of triangle VZX is thus;
700 cm^2 - 490 cm^2 = 210 cm^2
Answer:
C. 0.0067
Step-by-step explanation:
6.7*10^-3
Write in standard form.
This question pertains to scientific notation, a way to easily express really large or really small numbers.
You'll first notice that 10 has a negative exponent. This tells you that the number is going to be smaller than 10.
This is because 10^-3 translates to 1/10^3 based on exponent rules
With that, you know that your equation is 6.7/10^3
<u>You can simplify that to:</u>
0.0067
In case you didn't know how I got there, 10^3 simply means 10 multiplied by itself 3 times.
The other method would be to look at your answer choices. Since we have a negative exponent, we can eliminate D.
Next, since we have a positive coefficient (6.7), we can eliminate A and B.
That leaves us with the answer C. 0.0067
