Nonamiya [84]

Answer:

a.323.03hrs,

b.No. Time not enough

Step-by-step explanation:

One team takes $\frac{1}{600}$ of the job per hour,

Team two takes $\frac{1}{700}$ of the job together.

#to get what times it takes the two to clean together, we find the LCM of their work rates:

$LCM=\frac{1}{600}+\frac{1}{700}\\=\frac{13}{4200}\\$ #It takes the two13/4200 of the job per hour.

Combined work rate is thus $4200\div 13=323.08hrs$

Hence it takes the two teams 323.03hrs to clean the streets working together.

b.The crew team is set to begin in 1 week(7days). We therefore convert our time into days/weeks to verify viability;

Since one day equals 24hrs, the team will take

$323.03/24=13.46days$

13.46days>7days

#NO, The time is not enough since 13.46days is higher than the 1week(7day) timeline.

College student makes decorative Styrofoam Lions and Husky's which she sells each year. Each one uses 8 oz of Styrofoam and take

Travka [436]

Answer:

She should make 122 Styrofoam lions and 268 Styrofoam Husky's

The maximum profit, she makes is $1109

Step-by-step explanation:

The given information are;

The volume required to make each lion = 8 oz

The time it takes to make each lion = 35 minutes

The amount of profit each lion brings = $2.50

The volume required to make each Husky = 12 oz

The time it takes to make each Husky = 20 minutes

The amount of profit each Husky brings = $3

Let the number of lion Styrofoam cups she makes = x

Let the number of Husky Styrofoam cups she makes = y

Therefore, we have;

x × 35 + y × 20 = 9650..........(1)

x × 8 + y × 12 = 3840.............(2)

Dividing equation (2) by 8 and making x the subject, we get;

x × 8/8 + y × 12/8 = 3840/8

x + 4/3·y = 480

x = 480 - 4/3·y

Substituting the value of x in equation (1) gives;

(480 - 4/3·y) × 35 + y × 20 = 9650

16800 - 80/3·y = 9650

y = 268.125

x = 480 - 4/3·y = 480 - 4/3×268.125 = 122.5

Therefore, she can make 122 Styrofoam lions and 268 Styrofoam Husky's

The maximum profit, she makes is therefore given by the following equation;

The maximum profit = 122 × 2.5 + 268 × 3 = $1109.

Point A, located at (-11,17) on the coordinate plane, is reflected over the x-axis to form point B. Then point B is reflected ov

zalisa [80]

Answer:

B = (-11, -17)

C = (11, -17)

Step-by-step explanation:

Reflection over the x-axis is accomplished by changing the sign of the y-coordinate:

(x, y) ⇒ (x, -y) . . . . . reflection over x-axis

Reflection over the y-axis is accomplished by changing the sign of the x-coordinate:

(x, y) ⇒ (-x, y) . . . . . reflection over the y-axis

B = (-11, -17)

C = (11, -17)

<em>Check</em>

Reflection over both axes negates both coordinates. It is equivalent to reflection over the origin, or rotation 180°.

A(-11, 17) ⇒ C(11, -17) . . . . . both coordinates change sign
