Answer:

$1900.80

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 9.9%/100 = 0.099 per year,

then, solving our equation

I = 4800 × 0.099 × 4 = 1900.8

I = $ 1,900.80

The simple interest accumulated

on a principal of $ 4,800.00

at a rate of 9.9% per year

for 4 years is $ 1,900.80.

Answer:

explanation below

Step-by-step explanation:

f(x) = 3x + 2

f(8) : replace x with 8    f(8) = 3 * 8 + 2 = 26

g(x) = 5x

g(a+2) : replace x with a+2    g(a+2) = 5 (a+2) or 5a + 10

Answer:

33. m∠1 = 135°, ∠3 = 45°, ∠2 = 135°

34. m∠1 = 80°, m∠2 = 100°, m∠3 = 100°

35. m∠1 = 90°, m∠2 = 25°

Step-by-step explanation:

33. The given parameters of the isosceles trapezoid are;

The measure of one of the base angles = 45°

For an isosceles trapezoid, the base angles are equal, therefore, we have;

The measure of the other base angle = m∠3 = 45°

Similarly, m∠1 = m∠2

Also, we have;

The sum of the interior angles in a trapezoid = The sum of the interior angles in a quadrilateral = 360°

∴ 45° + m∠3 + m∠1 + m∠2 = 360°

By substituting the known values, we have;

45° + 45° + m∠1 + m∠2 = 360°

From m∠1 = m∠2, we have;

45° + 45° + m∠1 + m∠1 = 90° + 2·m∠1 = 360°

2·m∠1 = 360° - 90° = 270°

∴ m∠1 = 270°/2 = 135°

m∠1 = 135° = m∠2

Therefore, we have;

∠3 = 45°, ∠1 = 135°, ∠2 = 135°

34. The measure of the base angles = 80°

∴ The measure of the other base angle = m∠1 = 80°

m∠2 = m∠3

80° + m∠1 + m∠2 + m∠3 = 360°

∴ 80° + 80° + 2·m∠2 = 360°

m∠2 = (360° - (80° + 80°))/2 = 100°

m∠2 = 100° = m∠3

35. The kite comprises of two half isosceles triangles

The base angles of the right half isosceles triangle = 65°

The angle formed by the diagonals of the kite = 90° (Perpendicular diagonals theorem)

Therefore, m∠1 = 90°

The diagonals bisect the angles at the vertices (Kite theorem)

Therefore, we have;

65° + 90° + m∠2 = 180°

m∠2 = 180° - (65° + 90°) = 25°

m∠2 = 25°.

Answer:

[tex]h = \frac{4}{n}[/tex]

Step-by-step explanation:

Isolate the variable by dividing each side by factors that do not contain the variable.

Hence, you get the following answer:

[tex]h = \frac{4}{n}[/tex]

Answer:

6(m-2)

Step-by-step explanation:

Alright. Let's start by finding the length of this shaded area. The full length of the rectangle is 'm', and the part that is not shaded has a length of '2', so if we subtract the full length and the non-shaded length, we will get the shaded part's length. This is 'm-2'. The width/height we already know...it is 6, so-

Answer is: 6(m-2)

Answer:

6(m-2)

Step-by-step explanation:

it is 6(m-2) because you would do the whole length of m minus 2.

Answer:

£34.05

Step-by-step explanation:

36/4=9

36/12=3

36/6=6

9x0.75=6.75

3x0.42=1.26

6x1.10=6.6

36x0.54=18.44

6.75+1.26+6.6+19.44= £34.05

Answer:

25%

Step-by-step explanation:

We know that there are ten purple popsicles. Together without the purple popsicles, there are 40 popsicles in total. Therefore there is a 10/40 chance to get purple. We need to turn this into a percentage so we do (10 / 40) x 100. This would equal to 25%, therefore, there is a 25% probability to get a purple popsicle.

Answer: -2 1/2

Step-by-step explanation:

First term = a = -40

Common ratio = 2nd term / First term = 20 / -40 = -1/2

5th term = ar⁴

5th term = -40 × (-1/2)⁴

5th term = -40 × 1/16

5th term = -2 1/2

so it is not

Answer:

The equation would be 1.5w + 187 = y.

Step-by-step explanation:

1.5 lbs per week

already 187

The variable would be 'w'

so 1.5w +187 = y

Answer:

Its point A. Or 4,5 or -4,5

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Quite simple. If x=4, the x+8, or 4+8= 12. 3x or 3*4 also happens to equal 12. Yw.

Answer:

c

Step-by-step explanation:

x + 8= 3x

if the answer is 4 then it would be 4 + 8 = 12 which makes sense. if you have a problem like this just put in what your trying to find and when the problem makes sense that's the solution.

The slope is 1/4 and 2 is the y intercept
