Answer:
2:3 unless it wants it in total, then 220:330
Step-by-step explanation:
it gives you the answer with the fraction. A ratio is basically saying with x:y for every x number of one thing there are y number of another. In this case we know 2/5 will be green, so how many will be red? 3/5. So for every 2 greens there are 3 reds.
Another way of looking at it is for the totals. there are 550 total, so 2/5 of that is green. 2/5 of 550 is 220, while 3/5 is 330 so that means of the 550, the ratio is 220:330. Kinda like simplifying fractions where 220/550 is the same thing as 2/5
Answer:
2 hours, 15 minutes
B.
Step-by-step explanation:
3:30 to 5:30 is 2 hours elapsed time.
5:30 to 5:45 is 15 minutes elapsed time.
2 hrs + 15 mins =2 hrs 15 mins.
Answer:
The slope is -1/2 and the y intercept is 1/4
Step-by-step explanation:
y = -1/2x + 1/4
This equation is in slope intercept form
y = mx+b where m is the slope and the y intercept is b
The slope is -1/2 and the y intercept is 1/4
The last graph because the slope is 40.
Slope equals rise over run
Rise is 4/ Run is 1
4/1=4
Slope (rate of change)=4
These are the steps, with their explanations and conclusions:
1) Draw two triangles: ΔRSP and ΔQSP.
2) Since PS is perpendicular to the segment RQ, ∠ RSP and ∠ QSP are equal to 90° (congruent).
3) Since S is the midpoint of the segment RQ, the two segments RS and SQ are congruent.
4) The segment SP is common to both ΔRSP and Δ QSP.
5) You have shown that the two triangles have two pair of equal sides and their angles included also equal, which is the postulate SAS: triangles are congruent if any pair of corresponding sides and their included angles are equal in both triangles.
Then, now you conclude that, since the two triangles are congruent, every pair of corresponding sides are congruent, and so the segments RP and PQ are congruent, which means that the distance from P to R is the same distance from P to Q, i.e. P is equidistant from points R and Q
