A teacher is having three students take care of 28 goldfish during the summer. He gave some of them to Alaina. Then he gave twic

-Dominant- [34]

Answer:

Alaina got 4, Miguel got 2(4) = 8 while Kira got 2(8) = 16

Step-by-step explanation:

Let the number he gave to Alaina be x. Now, we know he gave twice as many to Miguel. Amount received by Miguel is 2x.

He gave Kira 2 times what he gave Miguel, that is 2x * 2 = 4x

Addition of all these equals 28. We now get x

4x + 2x + x = 28

7x = 28

X = 28/7

x = 4

Alaina got 4, Miguel got 2(4) = 8 while Kira got 2(8) = 16

Find the area of the shaded region. Round the the nearest tenth.

Brums [2.3K]

Answer:

226.084 sq.m.

Step-by-step explanation:

Radius of circle = 18.6 cm

Area of sector = $\frac{\theta}{360^{\circ} }\pi r^2$

Area of sector = $\frac{123}{360} \times 3.14 \times (18.6)^2$

Area of sector = $371.157 m^2$

Area of triangle = $\frac{1}{2} \times a \times b \times Sin x$

a = OA = radius = 18.6 cm

b = OB = radius = 18.6 cm

x =123 °

Substitute the values in the formula

Area of triangle = $\frac{1}{2} \times 18.6 \times 18.6 \times Sin 123$

Area of triangle = $145.073 m^2$

So, Area of shaded region = Area of sector - Area of triangle

= $371.157 m^2-145.073 m^2$

= $226.084 m^2$

Hence the area of the shaded region is 226.084 sq.m.

Factor 28+56t+28w28+56t+28w28, plus, 56, t, plus, 28, w to identify the equivalent expressions. Choose 2 answers:

Effectus [21]

Answer: The factorization of $28+56t+28w$ $=28(1+2t+w)$

The factors of $28+56t+28w$ are 28 and 1+2t+w.

Step-by-step explanation:

The given expression : $28+56t+28w$

To factorize it, we need to find the common factor.

As 56 can be written as 2 x 28.

So, the above expression would become

$28+2\times28t+28w$

Now, taking 28 as common from all the terms, we will get

$28(1+2t+w)$

Thus, the factorization of $28+56t+28w$ $=28(1+2t+w)$

And the factors of $28+56t+28w$ are 28 and 1+2t+w.
