/log/(n+2) = /log/(n^2-70)

/n+2/ = n^2-70

/-n-2/____-n-2

.23 cents per ounce

Step-by-step explanation:

first you do 3.68/16=.23

The perimeter of the window is 3.93 feet.

Perimeter is the total length of the sides of a two-dimensional shape.

perimeter = πr

Where, r is the radius of the circle

And, π = 3.14

According to the given question.

The window is in the shape of semicircle.

Radius of the window = [tex]\frac{2.5}{2} = 1.25 feet[/tex]

Therefore, the perimeter of the window

= π × 1.25 ft

= 3.14 × 1.25

= 3.925

= 3.93 feet

Hence, the perimeter of the window is 3.93 feet.

Answer:

[tex]\tan \left(\frac{\pi }{2}\right)[/tex]

Step-by-step explanation:

We know that  tan(x) is defined as  sin(x)/cos(x):

[tex]\tan \left(\frac{\pi }{2}\right),\\\sin \left(\frac{\pi }{2}\right)=1,\\\cos \left(\frac{\pi }{2}\right)=0,\\\\[/tex]

[tex]\tan \left(\frac{\pi }{2}\right) = 1/0 \\[/tex]

1/0 is undefined as 0 is in the denominator

Answer: In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the  or the  and  define the length and width of the rectangle.

We can break one large  of the rectangle into several smaller boxes, using number bonds, to make the calculation easier. Then we add to get the area of the whole, which is the  or quotient.

Step-by-step explanation:

For example, you can find the product 23 × 37 by finding the area of a rectangle with a width of 23 and a length of 37: Of course, there is little gained if you simply multiply 23 × 37! What makes the area model useful is that area is a conserved quantity.

Answer:

volume = 338 x 20 = 6760 cm^3

Step-by-step explanation:

large rectangular top area = 14 x 22 = 308 cm^2

small rectangular top area = 6x5 = 30 cm^2

total top area = 308 + 30 = 338 cm^2

volume = 338 x 20 = 6760 cm^3

Step-by-step explanation:

When two angles are complementary they add up to 90 degrees

so for example if angle 1 is 2 angle two must equal 88 (they have to add up  to 90)

When two angles are supplementary they must add up to 180 (so it's the same process as table 1 but instead of adding to 90 it's 180)

Answer:

m<2 88,80, 65, 57, 50, 41, 35, 28, 14, 4

m<4 176, 164, 132, 108, 90, 81, 60,28, 11, 2

Step-by-step explanation:

complementary means they add up to 90°

m<2 88,80, 65, 57, 50, 41, 35, 28, 14, 4

supplementary means they add up to 180°

m<4 176, 164, 132, 108, 90, 81, 60,28, 11, 2

Answer:

a + 20 = 7*12 (multiplied both sides by 12)

a + 20 = 84 (calculated 7*12)

a = 84 - 20 (subtracted 20 on both sides)

a = 64 (calculated 84-20)
