Answer:

d.45 sq.ft

Step-by-step explanation:

Surface are i.e. Total surface area of square pyramid = a^2 + 2al

where a^2 is area of base

a is side of base

l is slant height

by the figure

a=3ft

a^2 = a×a

=3×3

=9ft

l=6ft

Surface area = a^2+2al

=9+2×3×6

=9+36

=45 sq.ft

Explain how you can prove RST is congruent to UVW by asa

garik1379 [7]

Well, to prove two triangles congruent by ASA, you have to figure out how two angles and a side of the triangles are congruent. So if you were to prove ∠R =∠U, and ∠T = ∠W, you would just have to prove that one of each of the sides were congruent. Sorry I couldn't help more.

Hope this helps! :)

Describe the transformation from the graph of f(x)=x to the graph of g(x)=1/3x PLEASE HELP!!

andrew11 [14]

The graph is shifted down k k units. Vertical Shift: Down 3 3 Units. The sign of a adescribes the reflection across the x-axis. −a - a means the graph is reflected across the x-axis. Reflection about the x-axis: None. The value of a a describes the vertical stretch or compression of thegraph. a>1 a > 1

Answer:

Number of Starbursts= 66

Step-by-step explanation:

Method:

The first step in working out the number of Starbursts in the bowl is to add the the ratios of 3 and 4, this gives you 7.

The next step is to divide the total number of sweets which is 154 by the value of 7, this gives you 22. This is because we are trying to find out the value of one in the ratio.

The final step would be to work out the number of Starbursts in the bowl. This can be done by multiplying 22 by the ratio for Starbursts which is 3, this gives you 66. This means that out of 154 sweets 66 of them were starbursts.

Set by step:

1) Add 3 and 4.

$3+4=7$
