1875/10000 as a simplified mixed number

Answers

Answer:

3/16

Step-by-step explanation:

step 1 Address the formula, input parameters & values.

Input parameters & values:

The given fraction = 1875/10000

step 2 Find GCD (Greatest Common Factor) for both numerator & denominator.

The GCF for 1875 & 10000 is 625

step 3 divide the numerator & denominator by GCD 625 and rewrite the fraction

= (1875/625) / (10000/625)

= 3/16

Thus, 3/16 is the simplified fraction for 1875/10000 by using the GCD or HCF method.

On one side of the square, it is 4.5 units long. The formula in finding the area of a square is A = s^2, where s is for side. The formula can also be A = s * s in which both formulas are the same and will result in the same answer. So overall, the area of the square is 20.25 or 20 ¼ square units. Hope this helps!

At Anthony's school, 260 of the 500 students are girls. At Theresa's school, 360 of the 600 students are girls. Whose school has the greater percent of girls.

Answers

Answer:

Theresa school has greater % of girls

Step-by-step explanation:

Given

Number of girl in the Anthony school = 260

Total student in Anthony school = 500

% of girl in the Anthony school = 260/500 * 100 = 52 %

Number of girl in the Theresa school = 360

Total student in Theresa school = 600

% of girl in the Theresa school = 360/600 * 100 = 60%

Theresa school has greater % of girls

Answer: [tex]\frac{7}{8}[/tex] or 0.875 in decimal form.

Step-by-step explanation:

Okay, so to solve this, the easiest method is to find a common denominator. While we could try using trial and error or if you know your tables really well, I don't so we will just multiply the denominators which is 8 and 4. We then multiply 8 and 4 which is 32.

To convert the fractions we have, we multiply both the numerator and denominator of each, by the multiple that multiplies the denominator to 32.

[tex]\frac{2}{4}[/tex] multiply both 4 and 2 by 8. Now we have [tex]\frac{16}{32}[/tex].

Same thing with the second number. We have [tex]\frac{3}{8}[/tex]. We multiply both the numerator and the denominator by 4. 3*4 is 12, 8*4 is 32.

Now we have [tex]\frac{12}{32}[/tex].

Now that both fractions have common denominators, we can add the numerators. [tex]\frac{16}{32} +\frac{12}{32} = \frac{28}{32}[/tex]

Now we have the answer, [tex]\frac{28}{32}[/tex], but is that it?

No. Now to find the final two answers, we simply [tex]\frac{28}{32}[/tex].

To simplify, we find the Greatest Common Factor of 28 and 32, which in this case happens to be 4. This is the highest number that either of those can be divided by to provide a normal whole number

After solving [tex]\frac{28/4}{32/4} =\frac{7}{8}[/tex]

That is our final answer. [tex]\frac{7}{8}[/tex].

If necessary, you can convert it to decimal form through simple division and end up with 0.875.

The Martz family pays a rate of 37.5 mills the property tax versus value of the home is 68,000 what is the property tax

Answers

If the property tax versus value of the home is 68,000 the property tax is $2,550.

Property tax

Using this formula

Property tax=Mills rate× Property value /1000

Where:

Mills rate=37.5

Property value=$68,000

Let plug in the formula

Property tax=37.5×68,000/1000

Property tax=$2,550,000/1000

Property tax=$2,550

Or

Convert the mills rates to dollar rate amounts by dividing the mill rate by 1,000 and then multiply it by the property value.

Property tax=37.5/1000×$68,000

Property tax=$2,550

Inconclusion the property tax is $2,550.

Find area of the composite figure

Answers

Answer:

517 sq. cm

Step-by-step explanation:

Area of the figure = area of triangle + area of semicircle

Area of semi circle = πr²/2

Area of semi circle = 3.14*15²/2

Area of semi circle = 353.25 sq.cm

Area of the triangle = a/2 * base * height

Base = 30cm

Height h² = 39² - 15²

h² = 1521 - 225

h² = 1296

h = 10.90cm

Area of triangle = 1/2 * 10.90 * 30

Area of triangle  = 15 * 10.90

Area of triangle = 163.5 sq. cm

Area of figure = 353.25 + 163.5

Area of figure = 516.75 sq. cm

Area of figure = 517 sq. cm
