mestny [16]
C.  The Triangle Inequality Theorem States that any two sides of a triangle must be greater than the third side. It cannot be A because 35+40= 75, which is not greater than 75. It cannot be B because 40+30= 70, which is not greater than 75. It cannot be D because 35+40= 75, which is not greater than 80. It is C because 40+30= 70, which is greater than 65.

The area of a rectangular field is 7050m^2. If the width of the field is 75m, what is its length?
sweet [91]

Answer:

Step-by-step explanation: Area =length × width

7050m^2 = X× 75m

7050 =75X

Divide both sides by 75

7050÷75 =75÷75

74m= X

A triangle has a base of 3⅖ inches and an area of 5⅒ square inches. Find the height of the triangle. Show your reasoning
N76 [4]

Answer: 3 in.

Step-by-step explanation:

Given

The base of the triangle is 3\frac{2}{5}\ inches

The area of the triangle is 5\frac{1}{10}\ inches^2

Solve mixed fraction

Base is

=3\dfrac{2}{5}\\\\=\dfrac{17}{5}\ in.

Area is

=5\dfrac{1}{10}\\\\=\dfrac{51}{10}\ in.^2

The area of the triangle is given by

\Rightarrow \text{Area A=}\dfrac{1}{2}\times \text{base}\times \text{height}

Insert the values to get the height

\Rightarrow \dfrac{51}{10}=\dfrac{1}{2}\times \dfrac{17}{5}\times \text{height}\\\\\Rightarrow \text{height}=3\ in.

The cost (in dollars) of making b bracelets is represented by 4 5b. The cost (in dollars) of making b necklaces is represented b
Leviafan [203]

Answer:

$(3b+2)

Step-by-step explanation:

The cost of making b bracelets = 4+5b

The cost  of making b necklaces = 8b+6.

To determine how much more it cost to make b necklaces than b bracelets, we simply subtract.

Extra Cost = Cost of b Necklaces-Cost of b Bracelets

=(8b+6)-(4+5b)

open the brackets

=8b+6-4-5b

Collect like terms

=8b-5b+6-4

=3b+2

It costs $(3b+2) more to make b necklaces than b bracelets.
