Jim and Regina can complete one job in 4 hours when working together. When working alone, Jim works twice as quickly as Regina.

• How long will it take each of them to do the job when working alone? Show all work supporting your answer.

• If Regina works as quickly as Jim, how long will it take both of them to do the job working together? Show all work supporting your answer.

Answers

Answer 1

Answer:

Jim = 6 hoursRegina = 12 hoursTogether at same rate = 3 hours

Step-by-step explanation:

Let Jim's speed  is J and Regina's speed is R and the work is W

We have:

(J + R)*4 = WJ = 2R

Substitute J with 2R:

(2R + R)*4 = W12R = W

Regina needs 12 hours to complete work

and

Substitute R with J/2:

(J + J/2)*4 = W 6J = W

Jim needs 6 hours to complete same work

If Regina works as quickly as Jim:

J + R = 2J

Then

Jim can complete 1/6 of work in one hour, they both can complete twice work:

1/6*2 = 1/3

Time to complete work:

1: 1/3 = 3 hours

At the BOBA CLUB you must be a member to buy boba. A membership cost $4. Once you are a member of BOBA CLUB each Boba drink is $2. At JACK’S BOBA you do not need to be a member. Anyone can walk in JACK'S BOBA shop and buy one drink for $3

Boba Club: y=2x+4
Jacks Boba: y=3x

Which is cheaper if you want to buy 7 boba drinks? How much cheaper? What is the solution to the system of equation?

Answers

Answer:

Boba Club is cheaper if you want to buy 7 Boba drinks. It's cheaper by 3.

Step-by-step explanation:

Boba Club: y=2x+4

Jack's Boba: y=3x

Replace the X variable with 7 for both equations. For Boba Club, multiply 2 by seven to get 14, then add four to get 18. For Jack's Boba, multiply 3 and 7 to get 21. Boba Club is cheaper. (What would you need 7 Boba drinks for though?)

Triangle ABC has vertices A(0, 6), B(-8, – 2), and

A dilation with a scale factor of 1/2 and center at the origin is
applied to this triangle.

What are the coordinates of B' in the dilated image?

Enter your answer by filling in the boxes.

B' has a coordinate pair of ( )

Answers

Answer:

B' has a coordinate pair of (-4, -1)

Step-by-step explanation:

We are given with the vertices of the triangle with B(-8,-2)

Please remember the rule of dilation

If a point (x,y) dilated for the scale factor of 'k', we do get image as (kx,ky)

Using this concept, we know scale factor is [tex]\frac{1}{2}[/tex] , we could get image as [tex](\frac{1}{2} (-8), \frac{1}{2} (-2))[/tex]

Let's simplify it

We do get (-4,-1)

Answers

Answer:

46

Step-by-step explanation:

let that number x

so [tex]\frac{23}{50} =\frac{x}{100}[/tex]

I do cross multiplication so 23*100=2300 and 50*x=50x

so 50x=2300 divide both by 50

x=46

Answer:

46

Step-by-step explanation:

since 100 is 50×2 you just do the same thing to 23 and multiply it by 2.

A scientist has two solutions, which she has labeled Solution A and Solution Each contains salt. She knows that Solution A is 40% salt and Solution B is 55% salt. She wants to obtain 90 ounces of a mixture that is 45% salt. How many ounces of each solution should she use?

A scientist has two solutions, which she has labeled Solution A and Solution Each contains salt. She knows that Solution A is 40% salt and Solution B is 55% salt. She wants to obtain 90 ounces of a mixture that is 45% salt. How many ounces of each solution should she use?

Our system of equations is given as

x + y = 90.... Equation 1

x = 90 - y

40% × x + 55% × y = 45% × 90 ounces

0.4x + 0.55y = 40.5....Equation 2

We substitute 90 - y for x in Equation 2

The value of g in the given right triangle is 13.20 units.

What is the Pythagoras theorem?

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse.

Given that, a right triangle with leg lengths f and g, and hypotenuse h, if f = 7 cm and h = 11.2 cm,

We need to find the value of g the hypotenuse,

So, here using the Pythagoras theorem,

f²+h² = g²

Therefore,

11.2²+7² = g²

g² = 174.44

g = 13.20

Hence, the value of g in the given right triangle is 13.20 units.

Step-by-step explanation:

Use A = 1400(1+0.02)^7.5

The 1400 is the starting money. The 1 is a constant. The 0.02 is the 2% in decimal form. And the 7.5 is years. I found that by just continually increasing it until it hit 1624.
