Answer:

{16, 17, 18, 19, 20, 21, 22,23, 24, 25}

Step-by-step explanation:

Given the set A={a|a an even number and 15< a< =25}

The inequality 15< a< =25 mean the set A consists of all the values between 15 and 25 with 25 inclusive (due to presence of the equal to sign)

Hence the required set A are {16, 17, 18, 19, 20, 21, 22,23, 24, 25}

Note that 15 is excluded from the set of number since 15<a i.e a > 15

Answer:

smaller triangle area = 73 1/3 ft^2

Step-by-step explanation:

The smaller triangle has a ratio of linear dimensions of 10/15 = 2/3 of that of the larger triangle. The area ratio is the square of this, so the area of the smaller triangle is ...

(165 ft^2)(2/3)^2 = (165 ft^2)(4/9) = 220/3 ft^2 = 73 1/3 ft^2

Yolanda makes wooden boxes for a crafts fair, She makes 100 boxes like the one shown, and she wants to paint all the outside fac

Gemiola [76]

A box has 4 sides, two short sides which are width by height and two long sides which is length by height.

A) Surface area = 2(LxH) + 2(WxH)

Surface area = 2(10x4) +2(6x4)

Surface area = 2(40) +2(24)

Surface area = 80 + 48

Surface area = 128 square inches for each box.

128 square inches x 100 boxes = 12,800 square inches.

B) 1 can covers 14,000 square inches which is greater then the total of the 100 boxes, so she will need to buy 1 can of paint.

For each value of U, determine whether it is a solution,

abruzzese [7]

Given u/7 - 1 = 7 and plugging in values for u,

For u = 28; 28/7 - 1 = 4 - 1 = 3; No
For u = -49; -49/7 - 1 = -7 - 1 = -8; No
For u = 42; 42/7 - 1 = 6 - 1 = 5; No
For u = 0; 0/7 - 1 = -1; No

Another way to find out which value would be a solution to u/7 - 1 = 7 is to solve for u.

u/7 - 1 = 7
u/7 = 7 + 1
u/7 = 8
u = 8*7
u = 56

The only solution to this equation is when u = 56.
