Point H is between points L and S. LS = 14x -21 LH = 15 HS = 8x What is the length of segment LS?Immersive Reader (5 Points)
Fofino [41]

Answer:

LS = 63

Step-by-step explanation:

Given

LS = 14x - 21

LH = 15

HS = 8x

Required

Determine the length of LS

Since H is between L and S, then

LS = LH + HS

Substitute 14x - 21 for LS, 15 for LH and 8x for HS

14x - 21 = 15 + 8x

Collect Like Terms

14x - 8x = 21 + 15

6x = 36

Divide both sides by 6

x = 6

Substitute 6 for x in LS = 14x - 21

LS = 14(6) - 21

LS = 84 - 21

LS = 63

<em>Hence, the length of LS is 63 units</em>

ololo11 [35]

Answer:

24 buckets

Step-by-step explanation:

Given that :

Dimension of rectangular block = 45 m by 38 m

A bucket of paint will cover 72m² of floor

Total area of floor : Length * Width

Total Area = (45m * 38m) = 1710 m²

Buckets of paint required :

Total area / Area per bucket

= 1710m² / 72m²

= 23.75 buckets

= 24 buckets

What term best describes the point where the three medians of a triangle intersects
kirill115 [55]
CENTROID is the term used to describe the point where the three medians of a triangle intersect.

Centroid is the center of gravity of the triangle. It is one of the triangle's point of concurrency. Aside from "center of gravity", it is also known as "center of mass" and "barycenter".

Centroids are always inside the triangle. Since, the centroid is where three medians intersect, each median divides the triangle into two smaller triangles of equal area. The centroid is exactly two-thirds the way along each median.

Other types of triangle centers aside from Centroids are:
1) incenter
2) circumcenter
3) orthocenter
