What is 16.2 simplified (and 121 simplified to)

Mathematics

Answer:

16.2 = $\frac{81}{5}$ and 121 = $\frac{121}{1}$

Step-by-step explanation:

16.2 can be simplified to its fraction form, which is $\frac{81}{5}$

$16+\frac{2}{10} =\frac{81}{5}$ which is 16.2

121 is already simplified since it is a whole number, but its fraction form would be $\frac{121}{1}$

$121+\frac{0}{10} =121$ which is 121

Find the area of the shaded

olga_2 [115]

Answer:

31.4 Square Inches

Step-by-step explanation:

Given a sector of a circle with the following dimensions:

Radius of the circle =6 inches

Central Angle of the sector =100°

$\text{Area of the sector=}\dfrac{\theta}{360^\circ}X\pi r^2$

$=\dfrac{100^\circ}{360^\circ}X\pi*6^2\\\\=10\pi\\\\=31.4$ Square Inches (correct to the nearest tenth of a square inch.)$

In the equation below a is a number between 0 and 1 8 x a = b which statement about the value of b is always true

Kamila [148]

Answer:

See Explanation

Step-by-step explanation:

Given

$0 \le a \le 1$

$8*a =b$

Required

Determine the true statement about b

The question is incomplete as options are not given. However, a general explanation is as follows:

Rewrite $8*a =b$

$b = 8 * a$

When a = 0

$b = 8 * 0 = 0$

When a = 1

$b = 8 * 1 = 8$

This means that:

For $0 \le a \le 1$

Then $0 \le b \le 8$

This means that: b is a number between 0 and 8

the area of a rectangular invitation card is 3/10 square foot. Given that the length of the card is 4/5 foot, find its perimeter

Troyanec [42]

Length = 4/5 ft
area = 3/10 ft.
Width = 3/10 ÷ 4/5 ft
= 3/10*5/4 ft
= 3/8 ft

Perimeter = 2(L+W)
= 2(4/5+3/8) ft
= 2(32+15)/40 ft
= 47/20 ft
= 2.35 ft

Full question :

Kyra is using rectangular tiles of two types for a floor design. A tile of each type is shown below: Two rectangular tiles, rectangle PQRS with vertices at P 5, 7. Q is at 9, 7. R is at 9, 12. S is at 5, 12 . Rectangle JKLM with vertices J 4, 5. K is at 6, 5. L is at 6, 10. M is at 4, 10. Which statement is correct? The two tiles are not similar because segment PQ is to segment QR is 4:5 and segment JK is to segment LM is 2:1. The two tiles are not similar because segment SP is to segment SR is 5:4 and segment MJ is to segment ML is 5:2. The two tiles are similar because segment PQ is to segment QR is 4:5 and segment JK is to segment KL is also 4:5. The two tiles are similar because segment SR is to segment ML is 2:1 and segment PQ is to segment JK is also 2:1.

Answer:

The two tiles are not similar because segment SP is to segment SR is 5:4 and segment MJ is to segment ML is 5:2.

Step-by-step explanation:

Given vertices which will be our points on the graph to trace the rectangular shapes:

For the first rectangular shape PQRS

P(5,7)

Q(9,7)

R(9,12)

S(5,12)

For the second rectangular shape JKLM

J(4,5)

K(6,5)

L(6,10)

M(4,10)

From the above we can find that the two tiles are not similar if we calculate using their x, y coordinates points(vertices) on the graph.

We can see from the options given that only the second option is correct because:

Line SP ratio to line SR in rectangle PQRS= 5:4

since SP=12-7=5 and SR=9-5=4

Therefore SP:SR = 5:4

Line MJ ratio to line ML in rectangle JKLM= 5:2

Since MJ= 10-5=5 and ML= 6-4=2

Therefore MJ:ML =5:2
