Forest rangers at a state park have observed a decline in the rate of trees per acre over a 5 year period. At the beginning of their observations, there was an average of 48 trees per acre. At the end of the 5 year period, there was an average of 42 trees per acre. If this trend continues how many trees per acre will there be in 4 1/2 years from the end of the 5 hear observation period?

Answer:

720 apples

Step-by-step explanation:

Let A be the number of apples in the small pack.

QTY for Small Cartons is 15A,

QTY for Big Cartons is 20(A+15) = 20A+300

From small cartons makes 25% or 1/4 of total, means the big carton makes 75% of total, or 3/4 of total. This also means the qty in big carton is 3 times of small carton

20A+300 = 3X (15A)= 45A

300 = 25A

A=12

Altogether = 15A+(20A+300) = 720 Apples

Answer:

A) Three and three ninths plus seven and six elevenths equals 10 and eighty seven ninety ninths

Step-by-step explanation:

Translate these into numerical values: 3 3/9 + 7 6/11 = 10 87/99

Find a common denominator or multiple that your denominator's (9 and 11) share. Their lowest common multiple is 99.

Take 3 3/9's and multiple the denominator by 11 to get your denominator of 99. What you do to your denominator also must be reflected in your numerator, so multiply it by the same factor of 11. You will get 3 33/99

Repeat for 7 6/11. Multiply your denominator (11) by 9 to get your denominator of 99. Do the same in the numerator (6) to get 54.

Now add your new values. 3 33/9 + 7 54/99
Your fractional values will add up to 87/99, and your whole number values will add up to 10. In this case, your fractional values do not exceed 1, so there is no need to work any further. Your final answer is 10 87/99

Answer:

153.86[tex]cm^{2}[/tex]

Step-by-step explanation:

For the white semicircles:

B=14cm is also the diameter, we know r=1/2diameter, so r=1/2(14)=7

Awhite=1/2π[tex]r^{2}[/tex]

Awhite=1/2π([tex]7^{2}[/tex])

Awhite=76.93[tex]cm^{2}[/tex]

For the blue semicircle:

B=14cm is also the radius

Ablue=1/2π[tex]r^{2}[/tex]

Ablue=1/2π([tex]14^{2}[/tex])

Ablue=307.72[tex]cm^{2}[/tex]

Shaded area:

Ashaded=Ablue-2(Awhite)

We use this equation since there are two white semicircles.

Ashaded=307.72-2(76.93)

Ashaded=153.86[tex]cm^{2}[/tex]











Answer:

615.44cm^2

Step-by-step explanation:

the big semicircle has a radius of 28cm

then you find the area of the big semicircle which is 1/2 x 28^2 x pi

pi=3.14

28^2=784

1/2 x 784 x 3.14=1230.88

the small semicircle has a radius of 14cm

1/2 x 14^2 x pi

1/2 x 196 x 3.14=307.72

since there are two small semicircle you need to times 307.72 by 2

307.72 x 2=615.44

now to find the area of the blue shaded you need to do

1230.88-615.44=615.44cm^2

Answer:

Step-by-step explanation:

Answer:

[tex] \displaystyle{ - \frac{9}{6} + ( - \frac{3}{5} ) }[/tex]

[tex]\displaystyle{ - \frac{9}{6} - \frac{3}{5} }[/tex]

[tex]\displaystyle{ = - \frac{9}{6} = - \frac{9 \times 5}{6 \times 5} = - \frac{45}{30} }[/tex]

[tex]\displaystyle{ = \frac{3}{5} = \frac{3 \times 6}{5 \times 6} = \frac{18}{30} }[/tex]

So,

[tex]\displaystyle{ = - \frac{45}{30} - \frac{18}{30} = - \frac{45 - 18}{30} = - \frac{37}{30} }[/tex]

There are six faces on the solid.

There are twelve edges on the solid.

There are eight vertices on the solid.

Step-by-step explanation:

The 3-D solid shape is a cube.

A cube is a regular hexahedron.

Hexahedron is a polyhedron with six faces (regular meaning all six are square).

So, there are six faces on a cube.

A cube has 12 edges because all faces are squares and congruent to each other, all 12 edges are the same length.

A vertex is a corner where edges meet. The plural is vertices.

a cube has eight vertices, a cone has one vertex and a sphere has none.

Answer:

180

Step-by-step explanation:

Here,

b=15

c=9

Now,

[tex]=b^{2}-5c\\\\=15^{2} -5*9\\\\=225-45\\\\=180[/tex]

Answer:

180

Step-by-step explanation:

b^2-5c

Substitute 15 in for b

15^2=225 -> 225-5c

Substitute 9 in for c

5(9)=45

225-45 = 180
