Your weekly base salary is $150. You earn $20 for each phone you taht you sell. The company policy is that as a part-time employ

Eduardwww [97]

Answer:

You can sell at least 40 phones each week.

Step-by-step explanation:

Given that:

Weekly base salary = $150

Earning on each phone = $20

Maximum amount that can be earned each week = $950

Let,

m be the number of phones.

20m + 150 ≤ 950

20m ≤ 950 - 150

20m ≤ 800

Dividing both sides by 20

$\frac{20m}{20}\leq \frac{800}{20}$

m ≤ 40

Hence,

You can sell at least 40 phones each week.

Callies family spends an average of $70 per month electric at that rate what can that family expect to pay electric for 1 year

ivanzaharov [21]

Answer:

$840

Step-by-step explanation:

Callies family spends an average of $70 per month electric. At that rate what can that family expect to pay electric for 1 year

Note that:

1 year = 12 months.

Hence, if:

1 month = $70

12 months = $x

Cross Multiply

$x = 12 × $70

$x = $840

Therefore, the amount that family can expect to pay in 1 year(12 month) for electric = $840

2-8x=10 looking for solution

leva [86]

Answer:

Step 1: Simplify both sides of the equation.

2−8x=10

2+−8x=10

−8x+2=10

Step 2: Subtract 2 from both sides.

−8x+2−2=10−2

−8x=8

Step 3: Divide both sides by -8.

−8x ÷ −8

8 ÷ −8

x=−1

Answer:

x=−1

A plane flies 452 miles north and then 767 miles west. What is the magnitude and direction of the plane's resultant vector?

pshichka [43]

Answer:

The plane's resultant vector is 890.3 miles, at an angle of 59.5° west of north.

Step-by-step explanation:

• To find the magnitude of the resultant vector, we have to use Pythagoras's theorem:

$\boxed{a^2 = b^2 + c^2}$

where:

a ⇒ hypotenuse (= resultant vector = ? mi)

b, c ⇒ the two other sides of the right-angled triangle (= 452 mil North, 767 mi West).

Using the formula:

resultant² = $452^2 + 767^2$

⇒ resultant = $\sqrt{452^2 + 767^2}$

⇒ resultant = 890.3 mi

• To find the direction, we can find the angle (labeled x in diagram) that the resultant makes with the north direction:

$tan (x) =\frac{767}{452}$

⇒ $x = tan^{-1} (\frac{767}{452} )$

⇒ $x = \bf{59.5 \textdegree}$

∴ The plane's resultant vector is 890.3 miles, at an angle of 59.5° west of north .
