Answer:

Step-by-step explanation:

First thing I would do is square the 14, and put it under the radical. Itll make the calculations a little bit easier.

14sqrt(2) = sqrt392

Use the definition of sine to find the value of a

sin(45) = opposite/hypotenuse = a/sqrt392

sin(45)=\frac{a}{\sqrt{392} }

a = 14

80% of x is equal to 100.<br><br> Find x.
xeze [42]

The number is 125 and the equation is 0.8x = 100

Step-by-step explanation:

80% of x is equal to 100.

Write an equation that shows the relationship of 80%, x, and 100

80% = 0.8

0.8x = 100

x = 100/0.8

x = 125

The number is 125 and the equation is 0.8x = 100

The sides of the base of a right square pyramid are 4 m in length , and its slant height is 8 m. If the lengths of the sides of
hram777 [196]

Answer:

16

Step-by-step explanation:

We have that the total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base, therefore it would be equal to:

As = 1/2 * p * h + l ^ 2

where l are the sides that measure 4, p is the perimeter that is the sum of the sides, and since there are 4 sides then it would be 16 (4 * 4), h the inclined height is 8, replacing we are left with:

As = 1/2 * 16 * 8 + 4 ^ 2

Ace = 80

Now, they say that the sides and the tilt height are multiplied by 4, the sides now measures 16, therefore the perimeter is 64 (4 * 16), the height would be 32, replacing would be:

As = 1/2 * 64 * 32 + 16 ^ 2

As = 1280

Therefore the factor would be:

1280/80 = 16

This means that to calculate the new surface area, it must be multiplied by the square of the number by which the sides and the inclined height are multiplied, that is, 4 ^ 2 = 16.

Which expression is equivalent to 6+4.5(32f-14f)
vichka [17]

Answer:

6 + 4.5(32f - 14f) = 6 + 81f

Step-by-step explanation:

Let us apply the distributive property to find an equivalent expression for:

6  + 4.5(32f - 14f)

For all real numbers a, b, and c, the distributive property says that:

a(b + c) = ab + ac

We apply this property to get:

6 + 4.5(32f - 14f) = 6 + 4.5 \times 32f  + 4.5 \times  - 14f

6 + 4.5(32f - 14f) = 6 + 144f   - 63f

We simplify the RHS to get:

6 + 4.5(32f - 14f) = 6 + 81f

Which of the following is a trinomial? c2 + c + 6 c2 − 16 −8c c3 + 4c2 − 12c + 7
Taya2010 [7]
Trinomial is defined as a polynomial with three terms separated by a operation (+,-). 

c² + c + 6     AND     c²<span> − 16 −8c    are trinomials.  

</span>c² + c + 6    
1st term: c²
2nd term: c
3rd term: 6

c²<span> − 16 − 8c
</span>1st term: c²
2nd term: 16
3rd term: 8c

When there is only one term it is identified as monomial; two terms is identified as binomial; polynomial means many terms.
