A square serving platter has an area of 124 in. 2. Which is the best estimate of the side length of the platter?

inysia [295]

Answer:

The correct answer is 11.1.

Step-by-step explanation:

Given:

Area of square platter $124in^{2}$ .

If side length of square platter is $x$ .

Then, $area=a^{2}$ .

As per question, $area=124inch^{2}$ .

So, $a^{2}=124$ .

Taking square both the sides, $\sqrt{a^{2} }=\sqrt{124}$ = $a=11.13$ .

Since the decimal is given in the hundredth position, we can estimate the value to the nearest tenth of a decimal.

Here, the hundredth place has the digit 3.

As 3 is less than 5, we don't add any number to the neighboring digit 1.

So, 3 becomes 0 and the number 11.13 becomes 11.10 and hence 11.1.

Therefore, the correct answer is 11.1

Quadrilateral math is a parallelogram. the area of math is _____.

Semmy [17]

The area of a parallelogram can be obtained by multiplying the length of the base by the height. Although no diagram is given, let us assume values of the base and height that would yield one of the choices as answers. Let us say that parallelogram MATH has the following values:

base = 6 m
height = 11 m

Area = base * height = 6 * 11
Area = 66 m^2

Therefore, the answer is B.

Suppose a ball is thrown upward to a height of h 0 meters. Each time the ball bounces, it rebounds to a fraction r of its previ

leva [86]

Answer: a) first 4 terms would be 10, 5, 2.5, 1.25.

b) $h_n=20(0.5)^{n-1}$

Step-by-step explanation:

Since we have given that

h₀ = 20

r = 0.5

As it is a geometric sequence.

So, hₙ would be

$h_n=h_0r^{n-1}\\\\h_n=20(0.5)^{n-1}$

First 4 terms would be

$h_1=20(0.5)=10\\\\h_2=20(0.5)^2=5\\\\h_3=20(0.5)^3=2.5\\\\h_4=20(0.5)^4=1.25$

Hence, a) first 4 terms would be 10, 5, 2.5, 1.25.

b) $h_n=20(0.5)^{n-1}$
