Answer:

<u>An improper fraction is when the numerator is a larger number than the denominator.</u> An improper fraction is also what the fraction is before you simplify it down to either a whole number or a mixed number.

An example of an improper fraction simplified to a whole number is 25/5. This can be simplified down to 5.

An example of an improper fraction simplified to a mixed number is 17/3. This can be simplified down to 5-2/3.

Answer:

An improper fraction is when the numerator of the fraction is larger than the denominator

For example, 13/4 is improper because 13 > 4

An improper fraction can be changed into a mixed number by dividing the numerator by the denominator

For example, 13 divided by 4 is 3 with remainder 1, or 3 1/4

Answer:

D. (6,6)

Step-by-step explanation:

Given the system of two equations

$\left\{\begin{array}{l}3x+5y=48\\ \\-3x+5y=12\end{array}\right.$

1. Add these two equations:

$3x+5y-3x+5y=48+12\\ \\10y=60\\ \\y=6$

2. Subtract these two equations:

$(3x+5y)-(-3x-5y)=48-12\\ \\3x+5y+3x-5y=36\\ \\6x=36\\ \\x=6$

Hence, the solution to the system is (6,6)

To find the height of a pole, a surveyor moves 160 feet away from the base of the pole and then, with a transit 6 feet tall, mea

Artyom0805 [142]

Answer:

306.8 feet

Step-by-step explanation:

Refer the attached figure .

A surveyor moves 160 feet away from the base of the pole i.e. ED = 160 m

Referring the image .

AC=ED=160 m

A transit i.e. AE is 6 feet tall.

AE = CD=6 feet

With a transmit the angle of elevation to the top of the pole to be 62° i.e. ∠BAC = 62°

To Find BC , use tigonometric ratio.

$Tan\theta = \frac{Perpendicular}{Base}$

$Tan 62^{\circ}=\frac{BC}{AC}$

$Tan 62^{\circ}=\frac{BC}{160}$

$1.88*160=BC$

$300.8=BC$

Now, the height of the pole = BC+CD =300.8+6=306.8 feet

Hence the height of the pole is 306.8 feet

Reduce to simplest form.

BigorU [14]

Convert 3 6/2 to an improper fraction so: 12/2
convert 2 4/5 to 14/5
multiply the numerators of the improper fractions so 12*14, which is 168.
multiple the denominators so 2*5, which is 10.
the new fraction is 168/10, so you divide 168 divided by 10, which is 16.8, or 16 4/5.
