The best way is to round off the two multiplicands, not to round off the "exact" answer.

Round off 25.311 to 25 and round off 4.65 to 5.  Then the approx. product is 125.

The answer would be:

<span>117.69615

BUT since it's asking you to estimate, I would put:

"about 117.69"

mr Goodwill [35]
Y = 2
X = 1
M = -2
B = ?
y=mx+b
2=-2(1)+b
2= -2 + b
+2 +2
4 = b
Therefore the equation is

A company is constructing an​ open-top, square-based, rectangular metal tank that will have a volume of 49 cubic feet. What dime
yawa3891 [41]

Answer:

b = 4.6 ft

h = 2.3 ft

Step-by-step explanation:

The volume of the tank is given by:

b^2*h=49

Where 'b' is the length of the each side of the square base, and 'h' is the height of the tank.

The surface area can be written as:

A=b^2+4bh\\A=b^2+4b*({\frac{49}{b^2}})\\A=b^2+\frac{196}{b}

The value of b for which the derivate of the expression above is zero is the value that yields the minimum surface area:

\frac{dA}{db} =0=2b-\frac{196}{b^2}\\2b^3=196\\b=4.61\ ft

The value of h is then:

h=\frac{49}{4.61^2}\\h=2.31\ ft

Rounded to the nearest tenth, the dimensions are b = 4.6 ft and h = 2.3 ft.

Please help me out!!!!
svetoff [14.1K]

Answer:

b= 70

Step-by-step explanation:

The sum of the opposite interior angles of a triangle is equal to exterior angle.

a+b = 140

We know that a = b since PQ = RQ  The angles opposite the equal sides in an isosceles triangle are equal

b+b = 140

2b =140

Divide by 2

2b/2 =140/2

b= 70
