Answer:

156 square inches

Step-by-step explanation:

We are given the two quantities

Let

length = l = 13 inches

and

Width = w = 12 inches

The formula for the area of rectangle is:

$Area=l*w$

where l is length and w is width

Putting the values of both that are given

$Area = 13*12\\=156$

so the area is 156 square inches ..

Escriba larazon entre la distancia (d)recorrida por un automóvil y el tiempo (t)empleando velocidad (v) es una razón entre dista

Romashka [77]

Answer:

V = d / t

Step-by-step explanation:

La velocidad se define como la relación entre la diatancia cubierta por un cuerpo y el tiempo necesario para cubrir esa distancia.

Si el tiempo empleado se da como (t)

La distancia recorrida se da como (d)

Podemos escribir la velocidad (V) en términos de disance y tiempo como;

V = d / t

List the sides of each triangle from shortest to greatest

Lelechka [254]

In every triangle, the largest side, is opposite the largest angle.

Also, the smallest side, is opposite the smallest angle.

a. $70^o\ \textgreater \ 60^o\ \textgreater \ 50^o$ so $|RQ|\ \textgreater \ |PR|\ \textgreater \ |PQ|$ ,

because RQ is opposite angle P, the largest,
PR is opposite angle Q , the middle
and PQ is opposite angle R, the smallest.

Greatest side: RQ

b. The sum of the measures of the interior angles of any triangle is 180°,

so

$m(A)+m(B)+m(C)=180^o\\\\50^o+45^o+x=180^o\\\\x=180^o-50^o-45^o=85^o$

thus, m(C) is the largest angle. This means the largest side is the side AB.

Answers:

a) RQ
b)AB

A fish tank has the shape of a rectangular prism. It has a length of 2 1/4 m, width of 7/8 m, and a height of 1 1/2 m. What is t

Andru [333]

Data:
l (lenght) = $2 \frac{1}{4} m$ = $\frac{9}{4}m$
w (widht) = $\frac{7}{8}m$
h (height) = $1 \frac{1}{2} m$ = $\frac{3}{2} m$
V (volume) = ?

Formula:
$V = l*w*h$

Solving:
$V = l*w*h$
$V = \frac{9}{4} * \frac{7}{8} * \frac{3}{2}$
$V = \frac{189}{64}m^3$

Transforming into a mixed fraction:

.....................189 |_64 → denominator
numerator←(61)....2.→Whole part

Stays like this: $2 \frac{61}{64}$

Therefore:
$V = \frac{189}{64}m^3\:\longrightarrow\:\boxed{\boxed{V=2 \frac{61}{64}m^3 }}\end{array}}\qquad\quad\checkmark$
