Evaluate the expression: 28-16+2x4’2

Answer:

The amount of annual interest you receive.

$500*8% = $40

The amount of interest you will receive for 8 years.

$40 x 8 years = $320

So after 8 years you will have a total of principal and interest .

$500 + $320 = $820

Answer:

CB is 8.8 ⇒ D

Step-by-step explanation:

In any triangle, the line segment joining the mid-points of two sides is parallel to the 3rd side and equal to half its length

In the given figure

∵ ABC is a triangle

∵ E and D are the midpoints of sides AC and AB

∵ CB is the 3rd side

→ By using the rule above

∴ ED // CB

∴ ED = [tex]\frac{1}{2}[/tex] CB

∵ ED = x + 0.7

∵ CB = 3x - 2.3

→ Substitute them in the equation above

∴ x + 0.7 =  [tex]\frac{1}{2}[/tex] (3x - 2.3)

∴ x + 0.7 =  [tex]\frac{1}{2}[/tex] (3x) -  [tex]\frac{1}{2}[/tex] (2.3)

∴ x + 0.7 = 1.5x - 1.15

→ Subtract 1.5x from both sides

∵ x - 1.5x + 0.7 = 1.5x - 1.5x -1.15

∴ -0.5x + 0.7 = -1.15

→ Subtract 0.7 from both sides

∵ -0.5x + 0.7 - 0.7 = -1.15 - 0.7

∴ -0.5x = -1.85

→ Divide both sides by -0.5

∴ x = 3.7

→ Substitute x by 3.7 in the expression of CB

∵ CB = 3(3.7) - 2.3

∴ CB = 11.1 - 2.3

∴ CB = 8.8

Answer:

A. 39%

Step-by-step explanation:

(125-90)/(90)=(35)/(90)=0.3889 or 39%

To find the percent increase, we need to divide the amount of change by the original amount.

Answer:

We conclude that the distance between two cities on a map = 6 inches.

Step-by-step explanation:

Given

Map scale:

1 in = 50 miles

Thus, in order to determine the distance in inches between two cities on a map, all we need is to divide the original distance between two cities i.e. 250 miles by 50 miles as 1 in = 50 miles.

so

Thus, we conclude that the distance between two cities on a map = 6 inches.

Answer:

D. y-2=-3(x-2)

Step-by-step explanation:

Answer:

<B = 47

Step-by-step explanation:

(5x+7) = (3x+23)

5x+7 = 3x+23

2x+7 = 23

2x = 16

2x/2 = 16/2

x = 8

<B = 3x+23

<B = 3(8)+23

<B = 24 + 23

<B = 47

Answer:

a < 3

Step-by-step explanation:

To do this, just solve it like an equation:

[tex]52 > -80 + 44a[/tex]

add 80 to both sides

[tex]132 > 44a[/tex]

divide both sides by 44

[tex]3>a[/tex]

or

[tex]a < 3[/tex]

Now, all you have to is graph a < 3

Answer:

a<3

Step-by-step explanation:

52>-80+44a

+80 +80

132>44a

3>a

a<3

Given:

The expression is

[tex]7x^3+5x+4x^5+2x^3[/tex]

To find:

The simplified form of given expression.

Solution:

We have,

[tex]7x^3+5x+4x^5+2x^3[/tex]

On combining like terms, we get

[tex]=(7x^3+2x^3)+5x+4x^5[/tex]

[tex]=9x^3+5x+4x^5[/tex]

Arranging the terms according to their degrees, we get

[tex]=4x^5+9x^3+5x[/tex]

Therefore, the simplified form of the given expression is [tex]4x^5+9x^3+5x[/tex].

Answer: 9 cm = LEngth

Step-by-step explanation:

27/3 = L

9 = LEngth

Answer:

The length is 9cm

Step-by-step explanation:

Formula = A = l * w

We have the width which is 3

And we have the area which is 27

All we need to do is work backward

A = l * w

27 = l * 3

27/3 = l * 3/3

9 = l

The length of the rectangle is 9

We can use that to check our work and see if its correct

Check

A = l * w

A = 9 * 3

A = 27 CORRECT

Now we know it's correct

Hope this helped!

Answer:

$113.81

Step-by-step explanation:

Find the cost for one book:

35.94 / 6 = 5.99

Multiply 5.99 with the number of books buying:

5.99 x 19 = 113.81

Answer:

41 units

Step-by-step explanation:

The Pythagorean  Theorem is given by :

[tex]a^2+b^2=c^2[/tex]

In a right ΔABC, AB = 40, BC = 9, & AC = x (AC is the hypotenuse)

Using the above theorem,

[tex]x^2=40^2+9^2\\\\x=41[/tex]

So, the value of AC is equal to 41 units.
