What is the approximate area of the shaded sector?

kodGreya [7K]

Answer:

C. $302 \: {cm}^{2}$

Step-by-step explanation:

$Area \: of \: sector = \frac{ \theta}{360 \degree} \times \pi {r}^{2} \\ \\ = \frac{135 \degree}{360 \degree} \times \pi {r}^{2} \\ \\ = \frac{135 }{360 } \times 3.14 \times {(16)}^{2} \\ \\ = \frac{108,518.4 }{360 } \\ \\ = 301.44 \\ \\Area \: of \: sector \approx \: 302 \: {cm}^{2}$

A certain television is advertised as a 59-inch TV (the diagonal length). If the width of

ArbitrLikvidat [17]

Answer:

32.9 inches

Step-by-step explanation:

this can be solved using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base = 49

c = hypotenuse = diagonal = 59

l² + 49² = 59²

l² = 59² - 49²

3481 - 2401 = 1080

find the square root

The director of a marching band asks the band members to line up in rows of four, but one is left over. Then she tries to line t

Hatshy [7]

There are 81 band members. :-)

4 rows of 20 = 80 ... with one left over = 80 + 1 (81)
6 rows of 13 = 78 ... with three left over = 78 + 3 (81)
7 rows of 11 = 77 ... with four left over = 77 + 4 (81)

RS 3560 becomes RS 4272 in 8 years at S.I. What will be the simple interest on Rs 6480 in 14 years at the same rate of interest?

Readme [11.4K]

Answer:

$RS\ 8,748$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

step 1

Find the rate of interest

in this problem we have

$t=8\ years\\ P=RS\ 3,560\\ A=RS\ 4,272\\r=?$

substitute in the formula above

$4,272=3,560(1+8r)$

solve for r

$8r=(4,272/3,560)-1$

$r=[(4,272/3,560)-1]/8$

$r=0.025$

convert to percentage

$r=0.025*100=2.5\%$

step 2

What will be the simple interest on Rs 6480 in 14 years at the same rate of interest?

we have

$t=14\ years\\ P=RS\ 6,480\\ A=?\\r=0.025$

substitute in the formula above

$A=6,480(1+0.025*14)$

$A=6,480(1+0.35)$

$A=RS\ 8,748$

Tony bowled 135 and 145 in his first two games. write and solve a compound inequality to find the possible values for a third ga

stira [4]

The average has to be at least 120 and at most 130
To calculate the average we need the sum of all values divided by the number of values, in this case, three (135, 145 and the third result).
120 ≤ (135 + 145 + n)/3 ≤ 130

In inequalities like this, what we change in one side, must be changed in the othe rside as well.
360 ≤ 280 + n ≤ 390
80 ≤ n ≤ 110
