Answer:Julie's average score was 76
Step-by-step explanation:
The formula for Average or mean is expressed as
Average = sum of terms / total number of terms.
Julie's first three test scores in biology were 65, 90 and 73.
The sum of the scores would be
65 + 90 + 73 = 228
The number of terms is the number of subjects. Therefore, the number of terms is 3. Therefore,
Average = 228/3 = 76
i believe it would be: 1/2y = x
y = 2.5
Answer:
To find the angle RST we have to first find SRT As the exterior angle adjoined with SRT =53°
so the SRT = Outer angle adjoined with angle SRT
angle SRT = 53° [°.° vertically opposite angles are equal]
Angle SRT + Angle STR + Angle RST = 180°
=>53° + 75° + Angle RST =180°
=> 128° + Angle RST = 180°
=> Angle RST =(180-128)°
= 52°
SO NO. <em><u>C</u></em> IS correct what Cate says is absolutely right
Answer:
Ethan can type 6 pages before meeting starts.
Step-by-step explanation:
Given that,
Ethan can type 2 pages in 1/8 hours
and his meeting is 3/4 hours late.
To find,
number of pages Ethan can type in 3/4 hours
<h3>1) </h3><h3>convert hours to minutes</h3>
1 hour = 60 minutes
1/8 hours = 1/8 * 60
= 7.5 minutes
3/4 hours = 3/4 * 60
= 45 minutes
<h3>2) </h3><h3>calculate pages typed</h3>
7.5 minutes = 1 page typed
1 minute = 1/7.5 pages typed
45 minutes = (1/7.5) * 45
= 6 pages typed
