Sally is having a problem with her puppy leaving the yard so she decides to build a new fence. The length of the yard is 7 feet
bezimeni [28]

The length = 6W + 7. 2L + 2W = 70. This is a system of equations. To get L by itself in the second problem, -2W from both sides to get 2L = 70 - 2W. Divide by 2 to get L = 35 - W. Now put them together. 6W +7 = 35 - W. Add W to both sides to get 7W + 7 = 35. Subtract 7 from both sides to get 7W = 28. Divide 7 to both sides to get W = 4. Now replace W with 4. 6(4) + 7 = L. 24 + 7 = 31. The length is 31. To check, do the second equation. 2(31) + 2(4) = 62 + 8 = 70. Your answer is 31.

A regular triangular pyramid has a base and lateral faces that are congruent equilateral triangles. It has a lateral surface are
TEA [102]
We know that

[lateral surface area of a regular triangular pyramid]=3*[area of one <span>equilateral triangle]
so
[area of one </span>equilateral triangle]=lateral surface/3-----> 81/3-----> 27 ft²

[<span>surface area of the regular triangular pyramid]=lateral area+area of the base

area of the base is equals to the area of the lateral sides because are </span>equilateral triangles

therefore
area of the base=27 ft²

[surface area of the regular triangular pyramid]=81+27----> 108 ft²

the answer is
<span>the surface area of the regular triangular pyramid is 108 ft</span>²

A number cube is rolled 360 times and the results are recorded as follows: 41 ones, 54 twos, 62 threes, 75 fours, 33 fives, and
cestrela7 [59]
Let's attribute a to equal probability of 2 and b to equal probability of 3
A=54/360 B=62/360
"or" means you combine the probabilities which means that AvB =116/360
now simply divide 116 by 360 and you get your answer which is 0.32
