Matt has 80,000 in a savings account. The interest rate is 12% pre year and is not compounded. How much will he have in 4 months

1 answer:

7 0

Matt will earn 3,200 interest in 4 months.

Given:
principal : 80000
interest rate : 12%
term : 4/12 *4 months in a year

Simple Interest = Principal x Interest rate x term

S.I. = 80000 x 12% x 4/12
= 9600 x 4/12
S.I. = 3,200

OR
12% ÷ 12 month = 1% per month

S.I. = 80000 x 1% per month x 4 months
S.I. = 800 x 4 months
S.I. = 3,200

Solve for y, then graph equation <br><br> Y+2x=3

olga55 [171]

Answer:

y=-2x+3

Step-by-step explanation:

y+2x=3

y=3-2x

y=-2x+3

y=mx+b

where m=-2 and b=3.

So the slope for this function is -2 and the y-intercept is 3. You can easily graph this function.

What is the value of 'c' so that -9 and 9 are both solutions of x^2+c=103?

Gnoma [55]

Answer:

c = 22

Step-by-step explanation:

x^2 + c = 103 so if x is either + or - 9, x^2 = 81 so...

81 + c = 103

c = 22

The top of two poles of height's 20m and 14m are connected by the wire

Hatshy [7]

Answer:

The correct option is;

10 m

Step-by-step explanation:

The parameters given are;

Height of the first pole = 20 m

Height of the second pole = 14 m

The angle the wire connected to their top makes with the horizontal = 30°

The vertical height subtended by the inclined wire, h = The difference in height between the two poles = 20 - 14 = 6 m.

Let the horizontal distance between the two poles = D

Therefore;

The horizontal length of the wire = D

From trigonometric ratios, we have;

$tan(30 ^{\circ}) = \dfrac{h}{D} = \dfrac{6}{D}$

Which gives;

$D = \dfrac{6}{tan(30 ^{\circ}) } = 10.39 \ m\approx 10 \ m$

The correct option is 10 m.
