Rodger put $1,000 in a bank account that pays 5% annual simple interest. At the end of four years, how much interest has he earn

ed and what is the balance of his account
Mathematics
1 answer:
Kryger [21]3 years ago
3 0

Answer: He has earned $200 interest and the balance of his account is $1,200.

Step-by-step explanation:

Given: Principal : P = $1,000

Simple interest rate : r = 5% = 0.05

Time: t = 4 years

Simple interest = Prt

=1000\times0.05\times4=200

i.e. Simple interest = $200

Balance of account = Principal + Simple interest

=  $1,000 + $200

= $1,200

Hence, he has earned $200 interest and the balance of his account is $1,200.

Question of
Effectus [21]

Answer:

one solution

Step-by-step explanation:

3 -2x=5-x+3+4x

Combine like terms

3-2x = 8+3x

Add 2x to each side

3-2x+2x = 8+3x+2x

3 = 8+5x

Subtract 8 from each side

3-8 =8+5x-8

-5 =5x

Divide by 5

-5/5 = 5x/5

-1 =x

There is one solution

You are standing 30 meters from a hot air balloon that is preparing to take
Lerok [7]

Answer:

The distance to the top of the balloon is approximately 33.977 meters

Step-by-step explanation:

The (horizontal) distance from the hot air balloon from the observer, <em>l</em> = 30 m

The angle of elevation to the top of the balloon, θ = 28°

With the balloon standing upright, the distance to the top of the balloon, <em>d</em>, the height of the balloon, <em>h</em> and the horizontal distance to the balloon, <em>l</em>, form a right triangle, where;

d = The hypotenuse side

l = The leg adjacent to the reference (given) angle,

h = The leg opposite to the given angle, θ

By trigonometric ratios, we have;

cos\angle X = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}

From which we get;

cos\angle \theta = \dfrac{l}{d}

cos(28^{\circ})  = \dfrac{30 \ m}{d}

d = \dfrac{30 \ m}{cos(28^{\circ}) } \approx 33.977 \, m

The distance to the top of the balloon, <em>d </em>≈ 33.977 m

Find the unit rate with the numbers 12 and one and one half
kati45 [8]

Answer:

The value of the unit rate is 8

Step-by-step explanation:

we know that

To calculate the unit rate simply divide the first number by the second number

so

12:1\frac{1}{2}

Convert mixed number to an improper fraction

1\frac{1}{2}=1+\frac{1}{2}=\frac{1*2+1}{2}=\frac{3}{2}

substitute in the expression above

12:\frac{3}{2}=\frac{24}{3}=8

Please answer this these are all the points i got left XD
Kazeer [188]
Answer is choice B

The ratio of the sides (first to the second) is 11/9 since we divide 22/18 and reduce that fraction

Once we know the scale factor is 11/9, we square it to get (11/9)^2 = 121/81 which is the ratio of the first area to the second area
