Raul came home with $3.00 in his pocket. He had given Rene $1.50 on his way home. Pedro gave him $1.00 that he had borrowed last week. How much money did Raul have at the beginning of the day?

Answers

Answer: $3.50

Step-by-step explanation:

He came home with $3.00.

He gave Rene $1.50 which means that $1.50 was deducted from his money.

Pedro gave him $1.00 which added to his money.

Money he had therefore was:

= 3 + 1.50 - 1

= $3.50

If you cut away a triangle of area 59cm^2,the remaining area will be 85cm^2.Find the length of the side of the square before it was cut.?

Answers

Answer: side length = 12

Explanation

let x be the original area

Thus x - 59 = 85

=> x = 85 + 59
x = 144

Since we know the original shape is a square and Area of a square = side x side.

Find side length:

A = a^2

But A = 144

144 = a^2
12 = a

So the side of the square b4 it was cut is 12 cm

Answers

Answer:

Step-by-step explanation:

Find h when v = 20 and r = 3

Putting values in the formula

20 = (3.14)(3)2h

20 = (3.14)(9)h

20 = 28.26h

20/28.26 = h

R when v = 100 and h = 5

100 = (3.14)r2(5)

100/5 = 3.14r2

20 = 3.14r2

20/3.14 = r2

6.36 = r2

Square root on both sides

2.52 = r

The equation for the price of a baseball card that was bought for 5 dollars and has appreciated 5% yearly. Find the yearly calue of the card 25 years later

Answers

Answer:

The yearly value of the card 25 years later is $16.93.

Step-by-step explanation:

You can use the following formula to find the future value:

FV=PV(1+r)^n

FV= future value

PV= present value= 5

r=rate= 0.05

n=number of periods of time= 25

Now, you can replace the values in the formula:

FV=5(1+0.05)^25

FV=5(1.05)^25

FV=16.93

According to this, the answer is that the yearly value of the card 25 years later is $16.93.

Statement 2: m∠ ELD = (2x)°

Reason 4: Sum of angles on a straight line is equal to 180°

Statement 6: 2x = 56

Step-by-step explanation:

Since the first step talks about we being given m∠ ELG = 124°, the next thing we are given in the question is that; m∠ ELD = (2x)°

In statement 4,it is written that;

m∠ ELD + m∠ ELG = 180°

The reason behind this is that;

Sum of angles on a straight line is equal to 180°.

For reason 6, we are told it is a subtraction property.

Now the preceding statement gave us;

2x + 124 = 180

Which means that for subtraction property here, we will have;

2x = 180 - 124

2x = 56

The value of m<C can be obtained by using sine ratio as illustrated below:

Sine C = Opposite /Hypothenus

Sine C = 35 / 62
