1. Is triangle P’Q’R larger or smaller than triangle PQR? Explain how you know

Mathematics
1 answer:
Salsk061 [2.6K]3 years ago
7 0

Answer:

The length of the line is PQ as this line is parallel to the x - axis. So, the length of the line is the summation of 10 from second quadrant and 20 from first quadrant. So, the sum is 30. Hence the length of the line is 30 units.

Step-by-step explanation:

The length of a line segment can be measured by measuring the distance between its two endpoints. It is the path between the two points with a definite length that can be measured. Explanation: On a graph, the length of a line segment can be found by using the distance formula between its endpoints.

The triangles given below in the diagram are similar by; D: The SSS Similarity theorem.

<h3>How to interpret similar triangles?</h3>

From triangle similarity theorems, we know that;

If a segment is parallel to one side of a triangle and intersects the other two sides, then the triangle formed is similar to the original and the segment that divides the two sides it intersects is proportional.

Now, from the given diagram, we see the ratio of corresponding sides are congruent as;

45/30 = 54/36 = 36/24 = 1.5

Thus, the triangles are similar by SSS similarity theorem

A line has a slope of -3 and goes through
lesya692 [45]

Answer:

y=-3x+7

Step-by-step explanation:

slope intercept from is y=mx+b where m is slope and b is the intercept. so far we can plug in what we know. -8=y; 5=x; and -3=m.

(-8)=(-3)(5)+b. now solve for b which would give us b=7. now we plug in m and b int y=mx+b which gives us

y=-3x+7

For a science experiment Ella recorded the time, in seconds, to boil 650 grams of solution. Her results were 24.5, 23.2, 29.8, a
bagirrra123 [75]

Answer:

Mean of boiling times = 26.9 seconds

Step-by-step explanation:

Times ella recorded are given as;

24.5 seconds, 23.2 seconds, 29.8 seconds, and 30.1 seconds.

Now, we want to find the mean of these boiling times.

Formula for mean is;

Mean = sum of terms/number of terms

In this question,

number of terms = 4

Sum of terms = 24.5 + 23.2 + 29.8 + 30.1 = 107.6

Thus,

Mean = 107.6/4

Mean = 26.9 seconds
