Afina-wow [57]

Answer:

Step-by-step explanation:

Arc length of the circle is given by,

Arc length = $\frac{\theta}{360^{\circ}}(2\pi r)$

Area of the sector of a circle = $\frac{\theta}{360^{\circ}}(2\pi r)$

22). Arc length of the circle having central angle = $\frac{\pi}{3}$

= 60°

Arc length = $\frac{60^{\circ}}{360^{\circ}}(2\pi )(7)$

= $\frac{14\pi }{6}$

= 7.33 cm

23). Arc length of the circle having central angle = 225°

Arc length = $\frac{225^{\circ}}{360^{\circ}}(2\pi )(10)$

= 12.5π

= 39.27 km

24). Central angle = $\frac{5\pi }{4}$

= $\frac{5\times 180^{\circ}}{4}$

= 225°

Area of the sector = $\frac{225^{\circ}}{360^{\circ}}(2\pi )(11)$

= 43.20 yd²

25). Area of the sector = $\frac{270^{\circ}}{360^{\circ}}(2\pi )(14)$

= 65.97 yd²

It takes Megan 4 hours to read 3 chapter in her book How many chapters can she read in 10 hours

DerKrebs [107]

In 4 hours, she read 3 chapters.
In 1 hour, she reads 3/4 chapters.
In 10 hours, she reads 3/4 x 10= 3/2 x 5 = 15/2 = 7 and a half chapters.

Please don't leave half an answer for the points!

Answer:

T . . . labeling shown below
U
R
S

Step-by-step explanation:

Matrix multiplication of A(a rows, b columns) and B(b rows, c columns) will result in a product matrix of AB(a rows, c columns). This fact can be used to reduce the number of candidates for each product.

For the given factor tiles, the resulting product dimensions will be ...

[2, 3] [3, 2] [2, 2] ⇒ Q, R, S

[2, 3] [3, 3] [3, 2] ⇒ T, U, V

[3, 3] ⇒ W

1. For this 2×3 product, candidates are Q and T. The upper left term for the product in Q is (2)(3) +(1)(7) +(0)(8) = 13. The appropriate choice is T.

2. For this 3×3 product, candidates are U and W. The upper left term for the product in U is 9(2) +1(2) +9(5) +5(1) = 18 +2 +45 +5 = 70. The appropriate choice is U.

3. For this 3×2 product, candidates are R and V. The upper left term for the product in R is 1(4) +2(0) +4(1) = 4 +0 +4 = 8. The appropriate choice is R.

4. For this 2×2 product, there is only one candidate: S.
