Answer:
<em>Anna drove at an average speed of 49.73 km/h</em>
Step-by-step explanation:
<u>Average Speed</u>
If an object moves at different speeds to cover a certain total distance dt in a total time tt, the average speed is:
Anna drives a total distance of dt=45 km each day. One day she drives a distance of d1=25 km at v1=82 Km/h. The time taken for that distance is:
She takes t2=36 minutes to drive the remaining distance. 36 minutes is 36/60=0.6 h, thus the total time is:
The average speed is:
Anna drove at an average speed of 49.73 km/h
Choice 4, (x,y) (2x,y) I think is the answer, because when you multiply 2 by x, you're expanding the shape
Answer:
<STR = 38degrees

Complete Question:
In Rhombus QRST, diagonals RT and QS are drawn. If m<TSR = 104°, then which of the following is the measure of <SRT?
Sicne triangle STR is isosceles, hence the base angles are equal. Let the base angles be y
y+y+104 = 180
2y = 180-104
2y = 76
y = 38degrees
Since <STR = y, hence the measure of <STR = 38degrees
Answer:
7 is the card that must be removed.
Step-by-step explanation:
2 + 5 + 8 + 9 = 24 and dividing it by four (which is something you have to do when finding the average or mean) will get you 6 as an answer. So by getting rid of 7 you have a final mean as 6.
Answer:
A.)351 cubic inches
Step-by-step explanation:
The computation of the volume of the prism is shown below:
As we know that
Volume of the prism is
= Base × height
= 27 square inches × 13
= 351 cubic inches
hence, the first option is correct
And, the rest of the options are wrong
