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:

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.

[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]

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

When you convert the perimeter into the completed ft you have 144 you divide 24 into 144 to get 6

Answer:

it is 6

!don't attack if wrong!

Answer:

6 should be the x axis and 7 should be the y axis

Step-by-step explanation:

I think this is correct ;-;

This is correct because if you look at the question it shows that you need to describe the reflection as over the x axis or the y axis

Answer:

What type of math this is text me back!

Step-by-step explanation:

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
