Step-by-step explanation:

Area of Shaded part

= 2 * Area of Quarter-circle - Area of Square

= 0.5π(8)² - 8²

= 32(π - 2)cm².

Perimeter of Shaded part

= 0.5 * 2π(8)

= 8πcm.

The perimeter of the shaded part is 8πcm and the area of the shaded part is 8πcm and 0.5π(8)² - 8² respectively

Radius, r = 8 cm

= 1/2πr

Perimeter of Shaded part = 1/2 * 2πr

= 1/2 × 2 × π × 8

= 8πcm.

= 1/2πr²

Area of Shaded part

= Area of Quarter-circle - Area of Square

= 0.5π(8)² - 8²

Step-by-step explanation:

[tex]\begin{table}[]\begin{tabular}{lllll}Month & Amount & & & \\1 & \$14 & & & \\2 & \$14 & & & \\3 & \$14 & & & \\Sum & \$42 & & & \end{tabular}\end{table}[/tex]The given parameters are;

The monthly cost of Kelvin's Netflix plan = $14

The number of months over which the sum of the amount paid is calculated = 3 Months

The table that represents the parameters above is as follows;

[tex]\left\begin{array}{ccc}Month \ Number && Amount \ Payed \\\\1&& \$14.00\\2&&\$14.00\\3&&\$14.00\\\\ Sum \ of \ Amount&&\$42.00\end{array}\right[/tex]

The sum of the amounts Kelvin will pay over the next three months is $14 + $14 + $14 = $42.

Answer:

13,200 feet

Step-by-step explanation:

Answer:

13,200 feet

Step-by-step explanation:

In one mile, there are 5,280 feet.

You're trying to find how many feet are in 2.5 miles, so you can set up a proportion.

X = the number of feet in 2.5 miles.

[tex]\frac{1 mile }{5280 feet} = \frac{2.5 miles}{X feet}[/tex]

To find X, all you need to do is cross multiply.

So,

X = 5280 × 2.5 = 13,200 feet

Answer:

i. Cell phone cases

  Airpods

ii. x + y = 20 .............. 1

10.98x + 27.98y = 355.60 .............. 2

iii. x = 12, and y = 8

Step-by-step explanation:

Amount of sale = $355.60

Cost of Cell phone cases = $10.98

Cost of Airpods = $27.98

Number of phone accessories sold = 20

1. The variables to be considered in the question are:

i. Cell phone cases

ii. Airpods

2. Let the number of cell phone cases bought be represented by x, and that of airpods be represented by y.

Thus,

x + y = 20 .............. 1

10.98x + 27.98y = 355.60 .............. 2

From equation 1,

x = 20 -y

substitute the value of x in equation 2

10.98(20 - y) + 27.98y = 355.60

219.6 -10.98y + 27.98y = 355.60

17y = 136.60

y = [tex]\frac{136.60}{17}[/tex]

y = 8.0353

So that,

x = 20 -y

  = 20 - 8.0353

x = 11.9647

Thus,

x = 12, and y = 8

Answer:

26

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

22 successes out of a group of 40 means 22/40 were good. Now, simplify 22/40. Both can be divided by 2.

22/2 = 11

40/2 = 20

Now you have 11/20. Put this in decimal form and you have 0.55

Option A answer is 0.55

The proportion of a sample is the ratio of the number of successes or defeats to the total size of the sample, it is used for understanding which trend is more followed and also has many uses in the real world.

The size of the sample is 40.

There are 22 successes in the sample.

To find the proportion of success we have to find the ratio of 22 and 40 which is 11:20, and in numerical terms 0.55

Hence option A is correct, the proportion is 0.55

Answer:

The new function is g(x) = x² +1

Step-by-step explanation:

Explanation:-

Given that the function f(x) = x²

From graph ,

The parabola  y = x² is shifting to up with '1' units

                    y = x² +1

The new function is g(x) = x² +1

Verification:-

    y = x²+1

Put x=0 ⇒ y =1

The point (0,1) lies on the parabola y = x²+1

similarly put x =1 and y = 2

The Point (1,2) lies on the Parabola y = x²+1

∴ The new graph  y = x²+1

I am taking 7I+x to  mean 71+ x.

Answer:  y=1.837

Step-by-step explanation:

Step 1

Let y is inversely proportional to 7I+x be  mathematically be written as

y ∝ 1/7I+x

Introducing our proportionality of constant , K we have that

y ∝ 1/7I+x

y =K 1/7I+x

y= K/ 7I+xh

Step 2

so when x= 8, and y =2,  k becomes

y= K/ 7I+x

k=  y x (7I+x)

=2 x (71 + 8)

2x 79

=158

 when x= 15, y =?

y= K/ 7I+x

y= 158/  71 + 15

y=158/86

y=1.837

x = 118 degrees approximately

Step-by-step explanation:

Here, we want to get the measure of the angle marked x

We shall use the side facing it and apply the cosine rule

The side facing the angle measures 90

Thus, we have it that;

90^2 = 55^2 + 50^2 - 2(50)(55) cos X

2575 = - -5,500 cos X

X = cos^-1(-2575/5,500)
