Answer:    The equivalent expression for  is  

Step-by-step explanation:

The distance in feet that Karina swims in a race is represented by 4d - 4, where is d is the distance for each lap.

To get equivalent expression we factor the expression 4d-4

Greatest common factor is 4

Factor out 4 from the expression 4d-4

when we factor out 4, we divide each term by 4

The equivalent expression for  is

nicole is flying two kites. she has 104 feet of string out to one kite and 110 feet out to the other kite. the angle formed by t
Gnesinka [82]

Answer:

48.49 feet

Step-by-step explanation:

The diagrammatic sketch of the information provided in the question was attached in the image below.

From the image below, the distance between the two kites is denoted by (c) and can be determined by using the cosine angle rule which is expressed as:

c^2 = a^2 + b^2 -2ab cos \ C

where;

a = 110

b = 104

Cos C = 26°

Then;

c^2 = 110^2 + 104^2 -2(110)(104) cos \ 26 \\ \\  c^2 = 12100 + 10816- 22880 ( 0.8988) \\ \\  c^2 = 22916- 20564.544 \\ \\  c^2 = 2351.456 \\ \\  c= \sqrt{2351.456} \\ \\ \mathbf{ c = 48.49 \ feet}

A stainless steel patio heater is a square pyramid. The length of one side of the base is 23.4 in. The slant height of the pyram
Lerok [7]

Answer:

Step-by-step explanation:

By formulating a diagram u will form a triangle and u'll need to form a base from the square by finding it's diagonal then get half the diagonal as the base and the slanting height as the hypotenuse to find the height

23.4²+23.4²=DO

D²=1095.12

D=√1095.12

D=33.09

Base=33.09÷2=16.545

H²=88.6²-16.545²

H²=7576.22

H=√7576.22

H=87.04cm
