-5 1/2 divided by 2 1/3

Elena L [17]

The answer is -2 5/14
$[-5 \frac{1}{2} divided by 2 \frac{1}{3} =-2 \frac{5}{14}$
Change both into improper fractions $-5 \frac{1}{2} = \frac{-11}{2} and 2 \frac{1}{3} = \frac{7}{3} Then flipflop it to \frac{3}{7} .
 \frac{-11}{2} * \frac{3}{7} = \frac{-33}{14}
$ Divide -33 by 14=-2 $\frac{5}{14}$

What times what equals 21 but adds up to -22

attashe74 [19]

Let "what" and "what" be A and B

Put this in an algebraic equation
A * B = 21
A + B = -22

A must = -21 and B must = -1 , this is because two negatives multiply to make a positive

A + B = -22 , -21 +-1 = -22

Find the area of the region shaded in green. Use 3.14 to approximate pi.

8090 [49]

Answer:

254 cm² (to 3 s.f.)

Step-by-step explanation:

Area of shaded region

= area of large circle -area of smaller circle

$\boxed{area \: of \: circle = \pi {r}^{2} }$

Radius of large circle= 15cm

Radius of smaller circle= 12cm

Area of shaded region

= π(15²) -π(12²)

= 225π -144π

= 81π

= 81(3.14)

= 254.34

= 254 cm² (3 s.f.)

∠ 1 and angle∠2 are complementary angles. The measure of angle∠1 is 33°. The measure of angle∠2 is 3x°. Find the value of x. (Fi

Aleonysh [2.5K]

Complementary angles add up to 90 degrees.
m < 1 + m < 2 = 90
33 + 3x = 90
3x = 90 - 33
3x = 57
x = 19
