Monica's college runs on a trimester schedule, so she receives a bill 3 times a year for tuition. Each trimeste

BigorU [14]

Answer:

total cost for Samantha to get her degree = $5,128.2

Step-by-step explanation:

Number of trimesters per year = 3

Number of years = 4

∴ Total number of trimesters throughout college = 3 × 4 = 12 trimesters

Tuition per trimester = $2.350

Total tuition (12 trimesters) = 2.350 × 12 = $28.2

cost of books per trimester = $425

cost of books throughout college (12 trimesters) = 425 × 12 = $5,100

total cost for Samantha to get her degree = total cost of tuition + total cost of books

total cost for Samantha to get her degree = 28.2 + 5,100

total cost for Samantha to get her degree = $5,128.2

John has a rectangular-shaped field whose length is 62.5 yards and width is 45.3 yards. The area of the field is ________ square

oee [108]

Area = 2831.25 square yards

Perimeter =215.6 yards

EXPLANATION

The area and perimeter of a rectangular field are found using the formula for finding the area and perimeter of a rectangle respectively.

That means, area of the rectangular field is given by the formula,

$A= l\times w$

We just have to substitute
$l=62.5$ and $w= 45.3$ into the given formula and evaluate.

This implies that;

$A= 62.5\times 45.3$

This gives the area of the rectangular-shaped field to be;

$A= 2831.25$ square yards.

Now for the perimeter, we use the formula

$P=2w +2l$

Or

$P=2(w +l)$

Substituting the values for the length and width gives,

$P=2(62.5+45.3)$

$\Rightarrow P=2(107.8)$

$\Rightarrow P=215.6$

Hence the perimeter of the rectangular shaped field is 215.6 yards.

Why is the answer B?

Radda [10]

Remark

Whatever the original price, he gets 70% in the first instance.

He gets 80% in the second instance.

He gets 90% in the third instance

His total income is 240 dollars.

Let the original price be x

Equation

70%x + 80%x +90%x = 240

70% = 0.7 ; 80% = 0.8 ;90% = 0.9

Solution

0.7x + 0.8x + 0.9x = 240 Take out x as a common factor and add the decimals.

x (0.7 + 0.8 + 0.9) = 240

2.4x = 240 Divide both sides by 2.4

x = 240/2.4

x = 100

So the watches should have brought in 3*100 = 300 dollars.

He only brought in 240 dollars.

He lost 300 - 240 = 60 dollars.

The answer is B.

The difference between the two mass is 151950g

Data;

Mass a = 29.48kg
Mass b = 181,430g

<h3>Difference Between The Mass</h3>

To calculate the difference between the mass, we must do so in the same unit. i.e both mass a and mass b must be in the same unit.

<h3>Conversion of Mass from Kg to g</h3>

Let's convert mass a from kg to g

$1kg = 1000g$

Using this, we can find how many grammes are in 29.48kg

$1kg = 1000g\\29.48kg = x\\x = 29.48 * 1000\\x = 29480g$

Now we can find the difference between mass b and mass a

$b - a = 181430 - 29480 = 151950$

The difference between the two mass is 151950g
