Brainliest to first answer correct.

Mathematics
1 answer:
suter [353]3 years ago
5 0

Answer:

Option A is correct.

Step-by-step explanation:

The height of the rectangular pack is h1 = 4r

The height of the parallelogram = 2r + the height of equilateral triangles with a side of 2r

The height of equilateral triangle with a side of 2r = (side)/2*√3

=(2r)/2 *√3 = r√3

The height of the parallelogram h2 = 2r+r√3 = r(2+√3)

So,the ratio of h1 to h2 is :

4r : r(2 +√3)

Cancelling r we get

Hence, the ratio is  4 : 2 +√3

The coordinate bridge shows the cost of different numbers of bookmarks how many sense do for bookmarks cost.
pogonyaev

Answer:

54 cents

Step-by-step explanation:

The cost of bookmarks relating to the number of bookmarks is given by the graph shown. Therefore:

From the graph, we can determine the relationship between the cost of bookmarks and the number of bookmarks by using two points. The equation of a line passing through points (x_1,y_1)\ and\ (x_2,y_2) is:

y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\

From the graph, y represents the cost of bookmarks in cents and x represent the number of bookmarks. we can see that it passes through the point (2, 30) and (7, 90). Hence:

y-30=\frac{90-30}{7-2}(x-2)\\\\y-30=12(x-2) \\\\y-30=12x-24\\\\y=12x+6

The cost of 4 bookmarks (x = 4):

y = 12(4) + 6

y = 54 cents

Please help I'll give brainliest! This is number 6​
seraphim [82]

Answer:

< 1 = 125 degrees

< 2 = 55 degrees

< 3 = 125 degrees

< 4 = 55 degrees

< 5 = 125 degrees

< 6 = 55 degrees

< 7 = 125 degrees (given)

< 8 = 55 degrees

Step-by-step explanation:

1 and 3 are equal because they are vertical angles, therefore proving their congruence.

7 and 1 are equal because they're alternate exterior angles, which are congruent.

2 and 4 are vertical, which is congruent.

5 and 7 are vertical.

6 and 8 are vertical.
