Answer:

$x = 8$

Step-by-step explanation:

$\frac{7x}{4} - \frac{3x}{8} = 11 \\ \\ \frac{56x - 12x}{32} = 11 \\ \\ 44x = 352 \\ \\ x = \frac{352}{44} \\ \\ x = 8$

Usimov [2.4K]

Answer:

Option C is correct.

Step-by-step explanation:

Interest = $ 125.08

Rate = 6 %

We know that interest is given by

$S.I. = \frac{P R T}{100}$

$125.08 = \frac{P (6)(1)}{100}$

P = $ 2084.67

This is the value of interest. Thus option C is correct.

A 12 cm x 2 cm rectangle sits inside a circle with radius of 8 cm.

hammer [34]

Answer:

Diagram was not given.

Still I had drawn it, hope may it will helpful to you. So as per my diagram I had solved the sum.

The area of the shaded region is 176.96 ≈ 178 cm²

Step-by-step explanation:

Given:

radius of the circle = r = 8 cm

length of the rectangle = L = 12 cm

breadth of the rectangle = B = 2 cm

To Find:

Area of shaded region = ?

Solution:

$\textrm{Area of rectangle} = Length\times Breadth\\= L\times B\\= 12\times 2\\= 24\ cm^{2}$

$\textrm{Area of Circle} = \pi \times (radius)^{2} \\=\pi \times r^{2}\\=3.14\times 8^{2}\\=200.96\ cm^{2}$

Now, The Area of Shaded region will be

$\textrm{Area of Shaded region}=\textrm{Area of Circle}-\textrm{Area of Rectangle}\\=200.96 - 24\\=176.96\ cm^{2} \\=178\ cm^{2}\........... \textrm{Rounded to tenth}$

The area of the shaded region is 176.96 ≈ 178 cm²
