Vita saved $72 last December. This amount represents 2/9 of the total amount she saved last year. What is the total amount Vita

GrogVix [38]

$\dfrac{2}{9} \text { of the saving} = \$72$

-----------------------------------------------
Find 1/9 :
-----------------------------------------------
$\dfrac{1}{9} \text { of the saving} = \$72 \div 2$

$\dfrac{1}{9} \text { of the saving} = \$36$

-----------------------------------------------
Find 9/9 :
-----------------------------------------------
$\dfrac{9}{9} \text { of the saving} = \$36 \times 9$

$\dfrac{9}{9} \text { of the saving} = \$324$

-----------------------------------------------
Answer: The total amount is $324.

Which value of x is the solution of the equation 2(x – 4) + 7 = 3? (a) 1 (b) 6 (c) 2 (d) 0

pav-90 [236]

Answer:

Step-by-step explanation:

2(x - 4) + 7 = 3

2x + 2(-4) + 7 = 3

2x - 8 + 7 = 3

2x - 1 = 3

2x - 1 + 1 = 3 + 1

2x = 4

2x/2 = 4/2

x = 2

Hope this helps!!!

Use limits to find the area of the region bounded by the graph f(x)=4-2x^3 , the x-axis , and the vertical lines x=0 and x=1

gtnhenbr [62]

Answer:

$\frac{7}{2}$ square units.

Step-by-step explanation:

We have to use limits to find the area of the region bounded by the graph $f(x) = 4 - 2x^{3}$ , the x-axis, and the vertical lines x=0 and x=1.

So, the area will be

A = $\int\limits^1_0 {(4 - 2x^{3})} \, dx$

= $[4x - \frac{x^{4}}{2} ]^{1} _{0}$

= $4 - \frac{1}{2}$

= $\frac{7}{2}$ square units. (Answer)
