What is the value of x 2(2x+2)=−4

Answers

Answer 1

Answer:

x = -2

Step-by-step explanation:

1. Distribute 2 into the parentheses.

2(2x+2) = -4

4x+4 = -4

2. Subtract 4 from both sides.

4x = -8

3. Divide 4 from both sides.

4x = -8

[tex]\frac{4x}{4}[/tex] = [tex]\frac{-8}{4}[/tex]

x = -2

by what percentage will an amount gro in 10yeare if it is invested at 5% p.a. compounded monthly​

Answers

Answer:

64.7%

Step-by-step explanation:

To solve this problem we use compounded interest formula.

[tex]a = p(1 + (r \div n))^{nt} [/tex]

a = amount

p = principle

r = interest rate

n = number of times compounded in a period

t = time period

[tex]a = 1000(1 + (.05 \div 12)^{12 \times 10} [/tex]

a = 1647.01

1647.01-1000 = 647.01

647.01/1000 = 0.64701

0.64701*100% = 64.7%

It takes approximately 8 working days for an orderof number 6 screws to arrive once the order has beenplaced. (Refer to Problem 6-18.) The demand fornumber 6 screws is fairly constant, and on the aver-age, Lila has observed that her brother's hardwarestore sells 500 of these screws each day. Because thedemand is fairly constant, Lila believes that she canavoid stockouts completely if she only orders thenumber 6 screws at the correct time. What is theROP?

Answers

Answer:

Step-by-step explanation:

Given that:

The demand for number 6 screws is fairly constant and  brother's hardware store sells 500 of these screws each day.

So;

The demand for number 6 screws =  500 screws /day

It takes approximately 8 working days for an order of number 6 screws to arrive once the order has been placed.

Delivery time-frame  = 8 days

Lila believes that she can avoid stockouts completely if she only orders the number 6 screws at the correct time.

i.e Lila would want to have 8 days (delivery time-frame) × 500 screws /day

= 4000 screws

This implies that these 4000 screws will only last for 6 days.

Thus Lila ROP ( reorder point) will be to reorder for another set of  screw the day she receives the current shipment, this implies that after 8 days she would have sold the present 4000 screws and she will be expecting a new re-stock.

In this exercise, we have to use our knowledge of finance to calculate the number that should be replenished in the stock, in this way:

This implies that these 4000 screws will only last for 6 days.

The exercise statement states that:

6 screws is fairly constant and  brother's hardware store sells 500 of these screws each day.

With this information we can also say that:

It takes approximately 8 working days for an order of number 6 screws to arrive once the order has been placed.

Then, performing the calculation, we find:

[tex] 8 * 500 = 4000 screws[/tex]

In still water, a boat averages 18 miles per hour (mph). It takes the same amount of time to travel 33 miles downstream (with the current) as it takes to travel 21 miles upstream (against the current). What is the rate of the water's current

Answers

Answer:

The rate of the water current is 4mph

Step-by-step explanation:

Let c= the rate of the current in mph

18+c= the rate of the boat going downstream in mph

18-c= the rate of the boat going upstream in mph

t = time in hrs for both upstream and downstream trips

Going downstream:

33=(18+c)*t (1)

Going upstream

21=(18-c)*t (2)

From (1)

33=(18+c)*t

t=33/1(8+c)

Substitute t=33/(18+c) into (2)

21=(18-c)*t

21=(18-c)*33/(18+c)

Cross product

21(18+c)=33(18-c)

378+21c=594-33c

21c+33c=594-378

54c=216

Divide both sides by 54

54c/54=216/54

c=4

Therefore,

The rate of the water current is 4mph

What are the coordinates of the point that partitions AB according to the part-to-part ratio 4:3?

Answers

Answer:

(-1,0)

Step-by-step explanation:

Here, our interest lies in finding the coordinates that splits the points (-5,-8) and (2,6) in the ratio 4:3. Let the point that does the splitting be called point P

The section formula is used here and the point we are having would be;

P = (mx2 + nx1)/(m+n) , (my2 + ny1)/(m + n)

From the question;

m = 4 and n = 3

x1 = -5, y1 = -8

x2 = 2 , y2 = 6

Plugging these values in the equation above, we have;

P = [4(2) + 3(-15)](3+4), [4(6) + 3(-8)]/(3+4)

P = (8-15)/7, (24-24)/7

= -7/7, 0/7

= (-1, 0)

The coordinates of point P is (-1,0)

if a truck starts from rest and its has acceleration of 4m/s 2. for second ,calculate its final velocity .what will be the distance travelled by the truck during the time interval?​

Answers

Answer:

The answer is given below

Step-by-step explanation:

Let us assume the truck accelerates for 4 seconds.

Given that:

Initial velocity (u) = 0 (starts from rest),

acceleration (a) = 4 m/s²

time (t) = 4 s

Final velocity (v) = ?,

Distance (s) = ?

To calculate the final velocity, we use the formula:

v = u + at

Substituting values gives:

v = 0 + 4(4)

v = 0 + 16

v = 16 m/s

The final velocity is 16 m/s²

To calculate the distance traveled by the truck, we use the equation:

[tex]s=ut+\frac{1}{2}at^2\\ Substituting\ values\ into\ the\ equation:\\s=0(4)+\frac{1}{2}(4)(4)^2\\s=0+2(16)\\s=0+32\\s = 32\ meters[/tex]

The distance traveled by the truck during the time interval is 32 meters

Resource Allocation You manage an ice cream factory that makes two flavors: Creamy Vanilla and Continental Mocha. Into each quart of Creamy Vanilla go 2 eggs and 3 cups of cream. Into each quart of Continental Mocha go 1 egg and 3 cups of cream. You have in stock 500 eggs and 900 cups ofcream. How many quarts of each flavor should you make in order to use up all the eggs and cream?

Answers

Answer:

in order to use up all the eggs and cream, the number of quarts of each flavor that should be made is;

Creamy vanilla x = 200 quarts

Continental mocha y = 100 quarts

Step-by-step explanation:

Let x and y represent the number of quarts of Creamy Vanilla and Continental Mocha that should be made in order to use up all the eggs and cream respectively.

For Creamy Vanilla go 2 eggs and 3 cups of cream

For Continental Mocha go 1 egg and 3 cups of cream.

Total number of eggs = 500 eggs

Total number of cream cups = 900 cups.

For the eggs;

2 eggs × x + 1 egg × y = 500

2x + y = 500 .......1

For the cream cups;

3 cups × x + 3 cups × y = 900

3x + 3y = 900

Dividing through by 3

x + y = 300 .......2

Solving the simultaneous equation;

Subtracting equation 2 from 1

(2x + y) - (x+y) = 500-300

2x -x = 200

x = 200

Substituting x = 200 into equation 2;

200 + y = 300

y = 300 - 200

y = 100

Therefore, in order to use up all the eggs and cream, the number of quarts of each flavor that should be made is;

Creamy vanilla x = 200 quarts

Continental mocha y = 100 quarts

Answers

Answer:

The correct locations are;

Part to part ratio is 3 cats to 5 dogs

Whole to part ratio is 10 pets to 2 rabbits

Part to whole ratio is 5 dogs to 10 pets

Step-by-step explanation:

The given information are;

The number of cats Jim has = 3

The number of dogs Jim has = 5

The number of rabbit Jim has = 2

The total number of pets Jim has = 3 + 5 + 2 = 10 pets

Therefore;

The fraction of the pets that are cats = 3/10

The fraction of the pets that are dogs = 5/10

The fraction of the pets that are rabbits= 2/10

Therefore we have;

Part to part ratio = 3/10 cats to 5/10 dogs = 3 cats to 5 dogs

Whole to part ratio → 10 pets to 2 rabbits

Part to whole ratio → 5 dogs to 10 pets.

mC = 77°

mAB = 154°

Step-by-step explanation:

The angle mB inscribes the arc mAC, so we have:

[tex]mB = mAC / 2[/tex]

[tex]mB = 110 / 2 = 55\°[/tex]

The sum of internal angles of a triangle is 180°, so in the triangle ABC we have:

[tex]mA + mB + mC = 180[/tex]

[tex]48 + 55 + mC = 180[/tex]

[tex]mC = 180 - 48 - 55[/tex]

[tex]mC = 77\°[/tex]

Using again the property of inscribed angles, we have:

The figure below is formed by 8 identical rectangles and 1 triangle. Find the
area of the shaded triangle​

Answers

Answer:

Step-by-step explanation:

Base of triangle  = length of the rectangle

Since, all are identical rectangles,

Length of a rectangle= 36/2 = 18 cm

Base of triangle = 18 cm

Height of triangle = length of the rectangle + width of the rectangle

Width of 6 rectangles = 36

Width of 1 rectangle = 36/ 6 = 6 cm

Height of the triangle = 18 + 6 =  24 cm

Area of the shaded triangle = [tex]\frac{1}{2}base*height[/tex]

                                              = [tex]\frac{1}{2}*18*24[/tex]

                                              = 9 * 24

Use completing the square to solve for x in the equation (x-12)(x+4x)=9.

Answers

Answer:

x = 6 + 3 sqrt(21/5) or x = 6 - 3 sqrt(21/5)

Step-by-step explanation:

Solve for x over the real numbers:

(x - 12) (x + 4 x) = 9

(x - 12) (x + 4 x) = 5 x (x - 12):

5 x (x - 12) = 9

Divide both sides by 5:

x (x - 12) = 9/5

Expand out terms of the left hand side:

x^2 - 12 x = 9/5

Add 36 to both sides:

x^2 - 12 x + 36 = 189/5

Write the left hand side as a square:

(x - 6)^2 = 189/5

Take the square root of both sides:

x - 6 = 3 sqrt(21/5) or x - 6 = -3 sqrt(21/5)

Add 6 to both sides:

x = 6 + 3 sqrt(21/5) or x - 6 = -3 sqrt(21/5)

Add 6 to both sides:

Answer: x = 6 + 3 sqrt(21/5) or x = 6 - 3 sqrt(21/5)
