Answer:

When you multiply an odd number of negatives you get a negative result. When you multiply an even number of negatives you get a positive result.

First, multiply normally.

25x10x5

1100

Then determine whether the sign is positive or negative. Since there is an odd number of negatives, the sign is negative.

So, the answer is -1100.

In the adjoining figure, the parallel lines are marked by arrow lines. The value of angle 1 is:

dlinn [17]

Answer:

20°

Step-by-step explanation:

40°, 70° and 90° are the measures of the three angles of the quadrilateral.

Measure of fourth angle of the Quadrilateral

= 360° - (40° + 70° + 90°)

= 360° - 200°

= 160°

Measure of angle 1 will be equal to the measure of the linear pair angle of 160° as they are corresponding angles.

Thus,

$m\angle 1 = 180\degree- 160\degree$

$\implies\huge\purple{\boxed{ m\angle 1 = 20\degree}}$

Alternate method:

$m\angle 1 = 180\degree- [360\degree-(40\degree+70\degree+90\degree)]$

$\implies m\angle 1 = 180\degree- [360\degree-200\degree]$

$\implies m\angle 1 = 180\degree- 160\degree$

$\implies m\angle 1 = 20\degree$

Answer:

Step-by-step explanation:

We will use the tangent function since we know the opposite and adjacent sides.

Tangent = opposite/adjacent

Tan(e) = 16/10

Tan(e) = 1.6

Use the inverse tangent function to find the angle.

Arctan (1.6) = 57.9946168

Rounding this we get: 58°

At full price, Melvin would pay 1.6791.6791, point, 679 dollars per liter of gasoline. Using his loyalty card, Melvin only pays

aksik [14]

Answer:

$0.24

Step-by-step explanation:

Given:

At full price, Melvin would pay for per liter of gasoline = $1.679

Using his loyalty card, Melvin only pays = $1.439

Question asked:

How much less does Melvin pay per liter using his loyalty card?

Solution:

At full price, Melvin would pay for per liter of gasoline = $1.679

Using his loyalty card, Melvin only pays = $1.439

To find that that how much less amount Melvin pay for per liter of gasoline using his loyalty card, we will subtract the payment using loyalty card from payment without using loyalty card.

$1.679 - $1.439 = $0.24

Therefore, $0.24 less amount Melvin pay for per liter of gasoline using his loyalty card.
