Bill has $590 in his account. He earned $15 per hour for x hours, and deposited his earnings into
his account. Jeremy has $545 in his account. He earned $20 per hour for x hours, and deposited
his earnings into his account. They both worked the same number of hours and now have the same
amount of money in their accounts. Which of the following equations could be used to determine
the amount hours they worked?
A 15x + 590 = 20x + 545
B 20x + 590 = 15x + 545
C 15x + 590 + 20x + 545
D 590 – 15x = 545 – 20x

Answer:

54/120

Step-by-step explanation:

Ratio to 54 seconds to 2 minutes is 9 : 20

Find:

Ratio to 54 seconds to 2 minutes

Computation:

We know that,

1 minutes = 60 second

So,

2 minutes = 120 second

Ratio to 54 seconds to 2 minutes = 54 / 120

Ratio to 54 seconds to 2 minutes = 27 / 60

Ratio to 54 seconds to 2 minutes = 9 : 20

I got you bro!

Answer:

{x,y} = {4-1}

You might be wondering how I got this, well here are the steps:

System of Linear Equations entered :

  [1]    2x + y = 7

  [2]    x - 2y = 6

Graphic Representation of the Equations :

   y + 2x = 7        -2y + x = 6  

Solve by Substitution :

// Solve equation [2] for the variable  x  

 [2]    x = 2y + 6

// Plug this in for variable  x  in equation [1]

  [1]    2•(2y+6) + y = 7

  [1]    5y = -5

// Solve equation [1] for the variable  y  

  [1]    5y = - 5

  [1]    y = - 1

// By now we know this much :

   x = 2y+6

   y = -1

// Use the  y  value to solve for  x  

   x = 2(-1)+6 = 4

Solution :

{x,y} = {4,-1}

Step-by-step explanation:

The number of oranges in the shipment can the manager predict weighing 5 ounces will be 56. Then the correct option is B.

In parameter estimation, the expected value is an application of the weighted sum. Informally, the expected value is the simple average of a considerable number of individually determined outcomes of a randomly picked variable.

The expected value is given below.

E(x) = np

Where n is the number of samples and p is the probability.

A grocery store receives a shipment of 700 oranges. The manager randomly selects 25 oranges to weigh. In that sample, 2 oranges weigh 5 ounces.

Then the probability of the oranges that weigh 5 ounces is given as,

p = 2/25

Then the number of oranges in the shipment can the manager predicts weigh 5 ounces will be given as,

E(x) = 700 x 2 / 25

E(x) = 28 x 2

E(x) = 56

The number of oranges in the shipment can the manager predict weighing 5 ounces will be 56. Then the correct option is B.

Answer:

Bill should use 4.5 pounds of the candy costing 45 cents and 2.5 pounds of the candy costing 65 cents.

Step-by-step explanation:

With the information provided, you can say that the sum of the pounds of each type of candy is equal to 7, which can be expressed as:

x+y=7

Also, the statement indicates the 7 pound box costs $3.65 and you can say that the sum of the results of multiplying the price of each candy for the number of pounds is equal to $3.65, which is:

0.45x+0.65y=3.65

You have the following equations:

x+y=7 (1)

0.45x+0.65y=3.65 (2)

Now, you have to solve for x in (1):

x=7-y (3)

Then, you have to replace (3) in (2):

0.45(7-y)+0.65y=3.65

3.15-0.45y+0.65y=3.65

0.20y=0.50

y=0.50/0.20

y=2.5

Finally, you can replace the value of y in (3) to find x:

x=7-y

x=7-2.5

x=4.5

According to this, the answer is that Bill should use 4.5 pounds of the candy costing 45 cents and 2.5 pounds of the candy costing 65 cents.

Answer:

It is better to buy 20 g of flour 3 for 3.50

Step-by-step explanation:

It is given that 20g of 3 for 3.50

It means 3 packets of 20 g is 3*20 =60

So, 60g  is for 3.50

So, 1 g =[tex]\frac{3.5}{60}[/tex]=0.05833 per gram.

Now, let's find unit rate for 40 g of 2 for 9.

2 packets of 40 gram = 2* 40 =80 grams

So, 80 grams costs 9

So, 1 gram =[tex]\frac{9}{80}[/tex] =0.1125

So, it is better to buy 20 g of flour 3 for 3.50

Answer:

These are confusing Beth , b/c you have to remember that they will add to 100%

Step-by-step explanation:

so

green = 3*  yellow

100% = green + yellow + 35% + 25%

100% = 3* yellow + yellow +60%

40% = 4* yellow

10% = yellow

30% = green

there are 14 purples in the bag , which is 35% of total

14/.35 = 40

there are a total of 40 pins

so

4    are yellow  (10% of 40  or 40* 0.1)

12 are green    (30% of 40  or 40*0.3)

14  are purple  (35% of 40 or 40*0.35)

10  are grey  (25% of 40  or 40*0.25 )

Step-by-step explanation:

It’s the median

Out of all the options listed, the only one that does not show variation (spread) is the median.

The median is simply used to show the medium value of a data set. It cannot be used to tell the variation because it does not take into account all the values but rather the middle one alone.

The other options are wrong because:

In conclusion, only the median does not help with finding the variation of a dataset.

Answer: MN = 8.5

Step-by-step explanation:

Form it into a right triangle with MN being the hypotenuse (side opposite the right angle)

To make this a right triangle, plot a point at (8,-2) and connect the sides. The lengths of the legs that form the right angle are both 6 units. Use the Pythagorean theorem to solve for length of MN. a^2+b^2=c^2. (a and b are the legs that form the right angle and c is the hypotenuse)

6^2+6^2=c^2

36+36=c^2

72= c^2

8.48528137 = c.
