Answer: The lorry is traveling 10 mph over the expected speed.

Step-by-step explanation:

If 200 miles takes 4 hours, the speed is 200mi/4hr which is 50 mph.

If the distance is increased by 20%, the distance is 240 miles.

240mi/4hr = 60mph

The difference is 10mph

TanA+tanB+tanAtanB=1 If A+B=45 degree

djyliett [7]

Answer:

See below

Step-by-step explanation:

$\tan A+\tan B + \tan A.\tan B = 1\\\\ \implies \: \tan A + \tan B = 1 - \tan A.\tan B \\ \\ \implies \: \frac{\tan A + \tan B}{ 1 - \tan A.\tan B } = 1\\ \\ \implies \: \tan (A + B) = 1 \\ \\ \implies \: \tan (A + B) =\tan 45 \degree \\ \\ \implies \: A + B = 45 \degree \\ \\ thus \: proved$

Find the missing factor BBB that makes the equality true. -35x^6=(-5x^2)(B)−35x 6 =(−5x 2 )(B)minus, 35, x, start superscript, 6

Sveta_85 [38]

Answer:

$B=7x^4$

Step-by-step explanation:

The given equality is

$-35x^6=(-5x^2)B$

Take the term $(-5x^2)$ to the left hand side. This means the term $-35x^6$ will be divided by $(-5x^2)$

$\dfrac{-35x^6}{(-5x^2)}=B$

Now since both the numerator and denominator have negative sign the value of fraction will be positive.

$\dfrac{35x^6}{(5x^2)}=B$

Now $5\times 7=35$ and $x^{6-2}=x^4$

$7x^4=B$

So, the missing factor $B=7x^4$

Lines m and n are parallel. find the value of x.<br> A. 15<br> B. 20<br> C. 65<br> D. 115

torisob [31]

Answer:

Option B, x = 20

Step-by-step explanation:

<u>Step 1: Make an equation</u>

The values of 65 degrees and (3x + 5) are equal.

65 = 3x + 5

<u>Step 2: Subtract 5 from both sides</u>

65 - 5 = 3x + 5 - 5

60 = 3x

<u>Step 3: Divide both sides by 3</u>

60 / 3 = 3x / 3

<em>20 = x</em>

<em />

Answer: Option B, x = 20
