Mathematics

ozzi2 years ago
8 0

Answer:

  d = 15

Step-by-step explanation:

Divide the numbers

\frac{20}{16} =\frac{d}{12}

\frac{5}{4} =\frac{d}{12}

Multiply all terms by the same value to eliminate fraction denominators

12*\frac{5}{4} =12*\frac{d}{12}

Cancel multiplied terms that are in the denominator

12*\frac{5}{4} =d

Multiply the numbers

15=d

Move the variable to the left

d=15

Hence, d= 15.

What is the length of segment BC. ( ) units
weqwewe [10]

Answer:

BC = 144 units

Step-by-step explanation:

It is given a line segment BC.

D is the point on the line segment.

<u>To find the length of BC</u>

BC = 8x

CD = 3x + 8  and BD = 4x + 10

BC = CD + BD

8x = 3x + 8 + 4x + 10

8x = 7x + 18

x = 18

BC = 8x = 8 * 18 = 144 units

Therefore the length of segment BC = 144 units

An Olympic swimming pool is 50 m long, 25 m wide, and 1.5 m deep. How many Olympic pools would be filled by the dollar bills spe
Gelneren [198K]

Answer:

Number of dollars bills that can be fitted in Olympic pool = 1.67 billion.

Step-by-step explanation:

The dimensions of a dollar bill are 15.5956 cm by 6.6294 cm by 0.010922 cm. The U.S. federal government spent $3.8 trillion in fiscal year 2011.

An Olympic swimming pool is 50 m long, 25 m wide, and 1.5 m deep. How many Olympic pools would be filled by the dollar bills spent by the U.S. federal government in 2011

From above,

The volume for the dimension of the dollar bill = 15.5956 cm × 6.6294 cm × 0.010922 cm

The volume for the dimension of the dollar bill = 1.12922 cm³

The volume for the dimension of the dollar bill = 1.12922 × 10⁻⁶ m³

The volume of the pool = 50 m  ×  25 m  ×  1.5 m

The volume of the pool = 1875 m³

Number of dollars bills that can be fitted in pool = volume of the pool/volume of the dimension of dollar bills

Number of dollars bills that can be fitted in Olympic pool =1875 m³ / 1.12922 × 10⁻⁶ m³

Number of dollars bills that can be fitted in Olympic pool = 1,660,438,180

Number of dollars bills that can be fitted in Olympic pool = 1.67 billion.

If Ms. P wants to withdraw $900 from an account earning 4% average annual interest rate at the start of each year for 7 years, h
Ksju [112]

Answer:

Amount he must have in his account today is  $5,617.92

Step-by-step explanation:

Data provided in the question:

Regular withdraw amount = $900

Average annual interest rate, i = 4% = 0.04

Time, n = 7 years

Now,

Present Value = C \times\left[ \frac{1-(1+i)^{-n}}{i} \right] \times(1 + i)

here,

C = Regular withdraw amount

Thus,

Present Value = C \times\left[ \frac{1-(1+i)^{-n}}{i} \right] \times(1 + i)

Present Value = 900 \times\left[ \frac{1-(1+0.04)^{-7}}{ 0.04 } \right] \times(1 + 0.04)

Present Value = 936 \times\left[ \frac{1 - 1.04^{-7}}{ 0.04} \right]

Present Value = 936 \times\left[ \frac{1 - 0.759918}{ 0.04} \right]

Present Value = 936 × 6.00205

or

Present Value = $5,617.92

Hence,

Amount he must have in his account today is  $5,617.92
