A specific cars engine has a capacity of 5.1 Lof oil. How many quarts of oil does the engine have?

mr Goodwill [35]

ANSWER:

The engine have 5.39 qt approximately.

SOLUTION:

Given, a specific cars engine has a capacity of 5.1 L of oil.

We need to find how many quarts of oil does the engine have?

Number of quarts of oil is product of number of liters of oil and the number of quarts per liter.

We know that, one liter of liquid contains 1.056 quarts approximately.

Number of quarts of oil = number of liters of oil x number of quarts per liter.

Number of quarts of oil = 5.1 liters x 1.056 quarts.

Number of quarts of oil = 5.1 x 1.056

Number of quarts of oil = 5.389 qt.

Hence, the engine have 5.39 qt approximately

The bearing of point B from point A is 064°. Find the bearing of point A from point B.

Alex777 [14]

Answer:

The bearing of A from B is 296 degrees

Step-by-step explanation:

Here, we want to find the bearing of point A from point B

To find the bearing of point A from B, we simply subtract the bearing of B from A from 360

Mathematically, that will be;

360 - 64 = 296 degrees

2 u + 12 < 23 0,1 d + 8 > 0 3 - 4 r > 7 13 < 2 z + 3 6 ≥ 9 - 0, 15 i

BartSMP [9]

Answer:

Part 1) $u< 5.5$

Part 2) $d > -80$

Part 3) $r < -1$

Part 4) $z>5$

Part 5) $i\geq 20$

Step-by-step explanation:

The question is

Solve each inequality for the indicated variable

Part 1) we have

$2u+12$

subtract 12 both sides

$2u< 23-12\\2u$

Divide by 2 both sides

$u< 5.5$

The solution is the interval (-∞,5.5)

In a number line the solution is the shaded area at left of u=5.5 (open circle)

The number 5.5 is not included in the solution

Part 2) we have

$0.1d+8 >0$

subtract 8 both sides

$0.1d > -8$

Divide by 0.1 both sides

$d > -80$

The solution is the interval (-80,∞)

In a number line the solution is the shaded area at right of d=-80 (open circle)

The number -80 is not included in the solution

Part 3) we have

$3-4r> 7$

Subtract 3 both sides

$-4r>7-3\\-4r>4$

Divide by -4 both sides

Remember that, when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

$r < -1$

The solution is the interval (-∞,-1)

In a number line the solution is the shaded area at left of r=-1.1 (open circle)

The number -1.1 is not included in the solution

Part 4) we have

$13< 2z+3$

Subtract 3 both sides

$13-3$

Divide by 2 both sides

$5$

Rewrite

$z>5$

The solution is the interval (5,∞)

In a number line the solution is the shaded area at right of z=5 (open circle)

The number 5 is not included in the solution

Part 5) we have

$6\geq 9-0.15i$

Subtract 9 both sides

$6-9\geq -0.15i\\-3\geq -0.15i$

Divide by -0.15 both sides

Remember that, when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

$20\leq i$

Rewrite

$i\geq 20$

The solution is the interval [20,∞)

In a number line the solution is the shaded area at right of i=20 (closed circle)

The number 20 is included in the solution
