9514 1404 393

Answer:

  96 inches in 8 ft

Step-by-step explanation:

The number of inches is 12 times the number of feet. (Each foot is 12 inches.)

_____

Additional comment

The number of inches is proportional to the number of feet, so the number of inches in 8 feet will be half the number of inches in 16 feet. You may find it easier to divide the table value 192 inches by 2 than to multiply 8 feet by 12.

Answer:

12000

Step-by-step explanation:

sqrt144*1000000= sqrt144*sqrt10^6= 12*10^3=12000

The check using addition, the value of difference is added to the smaller value which should give the larger wingspan value.

The value of the wingspan of the butterflies aren't given, however, we could take hypothetical values for the wingspan of the two butterflies :

Wingspan of Butterfly A = 5.55 cm

Wingspan of Butterfly B = 4 cm

This means that, the difference in the wingspan is :

Wingspan of A - Wingspan of B

5.55 cm - 4 cm = 1.55cm

To check using addition :

The value of the difference added to the value of the butterfly with the lower wingspan should give the value of the wingspan of butterfly B(larger wingspan).

This means:

4cm + 1.55cm = 5.55 cm

Hence, the value of the difference is correct.

Answer:

x=5

Step-by-step explanation:

2(−4x + 5) - 4x + 1 = -49

-8x + 10 - 4x + 1 = - 49

-12x +11 = - 49

- 12x = - 49 - 11

- 12x = - 60

12x = 60

x = 5

Answer:

Mr . Li's salary = $ 2950

Step-by-step explanation:

Ratio  = 7 : 8

Total part = 7+8 = 15

Mr. Lim's part = 7/15

Total salary = $ x

Mr. Lim's salary = $ 2450

[tex]\dfrac{7}{15}*x= 2450\\\\\\x = 2450*\dfrac{15}{7}\\\\[/tex]

x = 370 * 15

x = $ 5550

Mr . Li's salary = [tex]\dfrac{8}{15}*5550[/tex]

                       = $ 2950

Answer:

The translation vector can be drawn on the coordinate grid or written as

\vec{v}=\langle a,b\rangle

v

=⟨a,b⟩

. For example, a translation vector that moves a figure

units right and

2

units down can be represented mathematically as

\vec{v}=\langle3,-2\rangle

v

=⟨3,−2⟩

, or graphically as

It doesn’t matter where the vector is positioned in the plane. In this figure, the vector starts at

(1,1)

(1,1)

and ends at

(4,-1)

(4,−1)

. But the initial point and terminal point of the vector are irrelevant. What matters is the length of the vector and the direction in which it points, so all you have to look at is how many units the vector moves in the

Answer:

x = 5

Step-by-step explanation:

7(2 - 6x) = -196

14 - 42x = -196

14 - 42x - 14 = -196 - 14

-42x = -210

-42x/-42 = -210/-42

x = 5

Answer:

5

Step-by-step explanation:

7(2 - 6x) = -196                Remove the brackets

7*2 - 7*6x = - 196

14 - 42x = - 195               Subtract 14 from both sides

-42x = - 196 - 14

-42x = - 210                    Divide by 42

x = - 210 / - 42

x = 5

Answer:

Below.

Step-by-step explanation:

I'll  write sin x as s and cos x as c so we have:

(1 + s +c)/(1 + s - c) = (1 + c)/s

Cross multiplying:

s + s^2 + cs  = 1 + s - c + c + cs - c^2

s  + s^2 + cs = 1 + s + cs - c^2

s^2 + c^2 + s - s + cs - cs = 1

s^2 + c^2 = 1.

- that is sin^2 x + cos^2 x = 1 which is a known identity.

Therefore the original identity is proved.
