Answer:

(a) v =  1536640/ m^2.

(b)  (i)   1186 m/s.

     (ii)   52.4g .

Step-by-step explanation:

(a)   The equation is v = k / m^2     where k is the constant of variation.

When m = 49, v = 640 so   640 = k / 49^2

k = 640 * 49^2

= 1,536,640.

Therefore the relation is v =  1536640/ m^2.

(b) (i)

When m = 36g,  the speed v = 1536640 / 36^2

= 1186 m/s.

(ii)   When the speed is  560 m/s :-

560 = 1536640 / m^2

m^2 = 1536640 / 560

=  2744

mass m = √2744

=  52.4g

Change each mixed number into an equal improper fraction a. 1 7/16, b. 11 5/9, c. 30 5/9, d. 10 10/13, e. 24 3/5, f. 129 1/2
elixir [45]

Answer:

a)

\dfrac{23}{16}

b)

\dfrac{104}{9}

c)

\dfrac{275}{9}

d)

\dfrac{140}{13}

e)

\dfrac{103}{5}

f)

\dfrac{259}{2}

Step-by-step explanation:

<em>" A fraction in which the numerator is greater than the denominator "</em>

We have to change each of the mixed fraction into improper fraction:

We know that the mixed fraction is converted into fraction as:

a\frac{b}{c}=\dfrac{a\times c+b}{c}

a)

1\frac{7}{16} could be written as:

=\dfrac{1\times 16+7}{16}\\\\=\dfrac{16+7}{16}\\\\=\dfrac{23}{16}

b)

11\frac{5}{9}

=\dfrac{11\times 9+5}{9}\\\\=\dfrac{99+5}{9}\\\\=\dfrac{104}{9}

c)

30\frac{5}{9}

\dfrac{30\times 9+5}{9}\\\\=\dfrac{270+5}{9}\\\\=\dfrac{275}{9}

d)

10\frac{10}{13}

\dfrac{10\times 13+10}{13}\\\\=\dfrac{130+10}{13}\\\\=\dfrac{140}{13}

e)

24\frac{3}{5}\\\\=\dfrac{24\times 5+3}{5}\\\\=\dfrac{100+3}{5}\\\\\dfrac{103}{5}

f)

129\frac{1}{2}\\\\\\=\dfrac{19\times 2+1}{2}\\\\=\dfrac{258+1}{2}\\\\=\dfrac{259}{2}

Oak Street and Elm Street run parallel to each other. When Main Street
kozerog [31]

Answer:

110°

Step-by-step explanation:

The consecutive interior angles theorem states that when two parallel lines are cut by a transversal, the pair of angles formed which lie inside the parallel lines  on the same side of the transversal are known as consecutive interior angles. This consecutive interior angles are supplementary (that is add up to 180°).

Therefore:

∠4 and ∠6 are consecutive interior angles. Hence:

∠4 + ∠6 = 180° (sum of co-interior angles)

∠4 + 70 = 180

∠4 = 180 - 70

∠4 = 110°

The product (x + 3y)(3x – y) =
Digiron [165]

Answer: 3x²-3y²+8xy

Step-by-step explanation:

When you multiply two factors, you want to use the FOIL method.

First

Outer

Inner

Last

(x+3y)(3x-y)                  [distribute by FOIL]

3x²-xy+9xy-3y²            [combine like terms]

3x²+8xy-3y²                 [rewrite]

3x²-3y²+8xy

Now, we know the product is 3x²-3y²+8xy.
