determine the area of the figure

Answer:

140%

Step-by-step explanation:

So a fraction can be expressed as: [tex]\frac{a}{b}[/tex] and if a number decreases by x%, the new number is (100-x)% the original value. So since the numerator decreases by 30%, it's not 70% the original value, and it's very similar with the denominator, with it only retaining 50% of it's original value. This gives you the formula: [tex]\frac{0.70a}{0.50b}[/tex]. You can rewrite the fraction as: [tex]\frac{1.4 * 0.5 * a}{0.5 * b}[/tex] in doing so it's easy to see that you can cancel out the 0.5 and get: [tex]1.4\frac{a}{b}[/tex]. This means the value is increasing by 1.4 or 140%

Answer:

140%

How to solve:

By substituting the point the slope passes through into slope-intercept form, we can calculate the y-intercept (b.) From here, we can use our slope and y-intercept values to set up the final equation.

Finding the y-intercept

Set up equation                                                         y = mx + b

Substitute                                                                   4 = 3/5(-5) + b

Simplify                                                                       4 = -3 + b

Simplify                                                                     +3    +3

Solve                                                                           7 = b

Creating final equation

Set up equation                                                         y = mx + b

Substitute                                                                   y = (3/5)x + 7

The expression that represents the area of the rectangle is 2x² + 6x − 20. Thus, the correct option is C.

A parallelogram in which adjacent sides are perpendicular to each other is called a rectangle. A rectangle is always a parallelogram and a quadrilateral but reverse statement may or may not be true.

The area of the rectangle is the product of its length and its width. Therefore, the area of the given rectangle is,

Area = (2x-4)(x+5)

       = 2x² + 10x - 4x - 20

       = 2x² +6x - 20

Hence, the expression that represents the area of the rectangle is 2x² + 6x − 20. Thus, the correct option is C.

The drug will decay to 82% of the initial dosage after 7.18 hours.

Finding the Decay constant(λ):

λ = 0.693 / (half-life)

we are given that the half-life is 47 hours

λ = 0.693 / (47)

λ = 0.01925 /hour

Time is taken for 82% decay:

Since decay is first-order, we will use the formula:

[tex]t = \frac{2.303}{0.0192} log\frac{100}{82}[/tex]

Final amount = 100*82/100 = 82 mg

Replacing the values in the equation:

Answer:

Step-by-step explanation:

Arithmetic sequence:

   a = first term = 4

   d = common difference =  second term - first term

       = 9 - 4

   d  = 5

[tex]\sf t_n =a +(n -1)*d[/tex]

   = 4 + (n - 1) *5

   = 4 + 5n - 5

    = 5n -1

Check; n= 1 ,  first term = 5*1 - 1 = 5 - 1 = 4

           n = 2,  second term = 5*2 - 1 = 10 -1 = 9

           n = 3, third term = 5*3 - 1 = 15 - 1 = 1

The next term, fifth term  = 5*5 - 1

                                          = 24

Answer:

B = 1.875

Step-by-step explanation:

given that A varies directly as B and inversely as C then the equation relating them is

A = [tex]\frac{kB}{C}[/tex] ← k is the constant of variation

to find k use the condition A = 12 when B = 3 and C = 2 , then

12 = [tex]\frac{3k}{2}[/tex] ( multiply both sides by 2 to clear the fraction )

24 = 3k ( divide both sides by 3 )

8 = k

A = [tex]\frac{8B}{C}[/tex] ← equation of variation

when A = 10 and C = 1.5 , then

10 = [tex]\frac{8B}{1.5}[/tex] ( multiply both sides by 1.5 )

15 = 8B ( divide both sides by 8 )

1.875 = B

The second choice (-6, -5 2/5, -4 1/5)

Step-by-step explanation:

1) Find the nth term by using the rule given. Foil them out.

A(n) = -6 + 1/5n - 1/5

A(n) = 1/5n - 31/5

2) Find the first term by substituting 1 into n.

a1 = 1/5(1) - 31/5

a1 = -6

3) Find the fourth term by substituting 4 into n.

a4 = 1/5(4) - 31/5

a4 = -27/5 or -5 2/5

4) Find the tenth term by substituting 10 into n.

a10 = 1/5(10) - 31/5

a10 = -21/5 or -4 1/5

Therefore, the second choice (-6, -5 2/5, -4 1/5) is correct.

The figure will have a triangle and a rectangle. The area of a triangle is 10 in² and the rectangle is 80 in². Therefore, the total area is 90 in².

This question requires your knowledge about the area of compound shapes. For solving this, you should:

The figure is composed of a triangle and a rectangle.

Therefore, you should sum the area of these geometric figures for determining the area of the irregular figure.

Area of the triangle= [tex]\frac{b*h}{2}[/tex]. The figure shows that: the base = 10 in and the height =2 in

Thus,  A_triangle=[tex]\frac{b*h}{2}=\frac{10*2}{2} =10 in^{2}[/tex]

Area of the rectangle = bh . The figure shows that:  the base = 10 in and the height =8 in

Thus,  A_rectangle=bh= 10*8=80 in²

A_total= A_triangle + A_rectangle

A_total= 10+80=90 in²

A_total= 90 in²
