4 to the 2nd power multiplied by 4 to the negative 3 power

Sati [7]

Note that for negatives, flip the place of the number, and change the power to positive

4^-3 = 1/(4³)

Multiply

1 x 4² = 4²

Divide. Note that when dividing powers with the same base, subtract the powers

4²/4³ = 1/4

1/4 is your answer

In triangle IJK, J = 800cm, k = 240 cm and angle I=173 degrees. Find the area of triangle IJK, to the nearest square centimeter.

wariber [46]

Answer:

11,700cm²

Step-by-step explanation:

Area of the triangle = 1/2*JK sin<I

Given

J = 800cm

K = 240cm

<I = 173 degrees

Substitute

Area of the triangle = 1/2 * 800 * 240 sin 173

Area of the triangle = 400 * 240sin 173

Area of the triangle = 400 * 29.25

Area of the triangle = 11,699.5

Area of the triangle to the nearest square centimeter is 11,700cm²

Half of the class likes chips 4th of the class likes pennies and the 7kids left want waterfront how many kids are in the class

S_A_V [24]

There are 28 kids in the class

Step-by-step explanation:

If an object is divided into different part, then

The total of all parts is 1
To find a missing part subtract the sum of the other parts from 1

∵ Half of the class likes chips

- Have means $\frac{1}{2}$

- Assume that the number of kids in the class is x

∴ The number of kids likes the chips = $\frac{1}{2}$ × x =

∵ 4th of the class likes pennies

- 4th means $\frac{1}{4}$

∴ The number of kids likes pennies = $\frac{1}{4}$ x

∵ The rest of the class want waterfront

- Find the rest of the class in terms of x by subtracting the sum

of the two given fractions from the number of kids

∴ The number of kids left = $x-(\frac{1}{2}x+\frac{1}{4}x)$

∵ $\frac{1}{2}x+\frac{1}{4}x=\frac{3}{4}x$

∴ The number of kids left = $x-\frac{3}{4}x$

∴ The number of kids left = $\frac{1}{4}$ x

∵ 7 kids left

- Equate $\frac{1}{4}$ x by 7 and find x

∴ $\frac{1}{4}$ x = 7

Multiply both sides by 4

∴ x = 28

There are 28 kids in the class
