Fatima is shaping this model to show 0.08 x 3. shade the correct amount of boxes that will show the product. fatima should shade

julia-pushkina [17]

Answer:

Fatima should shade 3 groups of 8 small squares or 24 small squares.

Step-by-step explanation:

Consider the provided information.

Fatima is shading this model to show 0.08 × 3. Shade the correct amount of boxes that will show the product.

Here 3 represents the number of groups and 8 represents the small square.

Multiplication is repeated addition.

We can rewrite the above multiplication as: 0.08 + 0.08 + 0.08

Therefore 0.08 × 3 = 0.24

Here 0.24 represents 24 small squares.

The required model is shown below:

Hence, Fatima should shade 3 groups of 8 small squares or 24 small squares.

Please hurry!!! Chose the equation below that represents the line that passes through the point (7,-2) and has a slope of -3

Varvara68 [4.7K]

Answer:

y + 2 = -3(x - 7)

Step-by-step explanation:

Write the equation using the point slope form $y - y_1 = m(x-x_1)$ . Substitute m = -3 and (7,-2).

$y --2 = -3(x-7)\\y + 2 = -3(x-7)\\y +2 = -3x +21\\y = -3x +19$

If y varies directly as (x+3) and inversely as (x-3) and y=21 when x=4, what is the equation for y in terms of x?

igor_vitrenko [27]

$\bf \qquad \qquad \textit{double proportional variation}
\\\\
\begin{array}{llll}
\textit{\underline{y} varies directly with \underline{x}}\\
\textit{and inversely with \underline{z}}
\end{array}\implies y=\cfrac{kx}{z}\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\$

$\bf \textit{\underline{y} varies directly as (x+3) and inversely as (x-3)}\implies y=\cfrac{k(x+3)}{x-3}
\\\\\\
\textit{we also know that }
\begin{cases}
y=21\\
x=4
\end{cases}\implies 21=\cfrac{k(4+3)}{4-3}\implies 21=\cfrac{k(7)}{1}
\\\\\\
\cfrac{21}{7}=k\implies 3=k\qquad thus\qquad \qquad \boxed{y=\cfrac{3(x+3)}{x-3}}$
