Help me with this question <br> Please I need help

Answer:

384 cm²

Step-by-step explanation:

The shape of the figure given in the question above is simply a combined shape of parallelogram and rectangle.

To obtain the area of the figure, we shall determine the area of the parallelogram and rectangle. This can be obtained as follow:

For parallelogram:

Height (H) = 7.5 cm

Base (B) = 24 cm

Area of parallelogram (A₁) =?

A₁ = B × H

A₁ = 24 × 7.5

A₁ = 180 cm²

For rectangle:

Length (L) = 24 cm

Width (W) = 8.5 cm

Area of rectangle (A₂) =?

A₂ = L × W

A₂ = 24 × 8.5

A₂ = 204 cm²

Finally, we shall determine the area of the shape.

Area of parallelogram (A₁) = 180 cm²

Area of rectangle (A₂) = 204 cm²

Area of figure (A)

A = A₁ + A₂

A = 180 + 204

A = 384 cm²

Therefore, the area of the figure is 384 cm²

What is 1/144 as an expression using a negative exponent
MrRissso [65]

ANSWER

{12}^{ - 2}

EXPLANATION

The given expression is

\frac{1}{144}

This is the same as:

\frac{1}{12 \times 12}

In index notation, we write this as

\frac{1}{ {12}^{2} }

To write this as a negative index, we use the property:

\frac{1}{ {a}^{m} }  =  {a}^{- m}

This implies that;

\frac{1}{ {12}^{2} }  =  {12}^{ - 2}

1 divided 5/12=-3/10
emmasim [6.3K]

Answer:

t = - 1/8

Step-by-step explanation:

t ÷ 5/12 = - 3/10

t × 12 ÷ 5 = - 3/10

12t/5 = - 3/10

12t × 10 = -3 × 5

120t = - 15

t = - 15/120

t = - 1/8

Thus, t divided 5/12 = - 3/10 => -1/8
