224 in 8 minutes. Use the unit rate to complete the table of values for the proportional relationship.

X. Y
2. ?
4. ?
6. ?

Answers

9514 1404 393

Answer:

  see attached

Step-by-step explanation:

It can be convenient to use mental arithmetic methods* to fill in this table.

Since the relationship is proportional the y-value for x=4 will be half that for x=8, so will be 224/2 = 112. Similarly, the y-value for x=2 will be half that for x=4, so will be 112/2 = 56.

Then the y-value for x=6 will be the sum of the y-values for x=2 and x=4, so will be 112 +56 = 168.

If you actually care to find the "unit rate," you can divide the y-value for x=2 by 2 to get the corresponding y-value for x=1: 56/2 = 28. The unit rate is 28.

_____

* Multiplication or division by 2 is simply a matter of doubling or halving. In most cases, it is easy to double a number, or to compute half of it. (If it isn't, you need to review your arithmetic facts.)

Craig likes to collect vinyl records. Last year he had 63 records in his collection. No he has 112 records. What is the percent increase in his collection? Round to the nearest whole.

Answers

Answer:

Collection increased by 78%.

Step-by-step explanation:

Last year number of vinyl records in Craig's collection = 63

Now he has number of vinyl records = 112

Number of vinyl records increased = 112 - 63 = 49

Percentage increase in his collection = [tex]\frac{\text{Number of records increase}}{\text{Number of records last year}}\times 100[/tex]

                                                               = [tex]\frac{49}{63}\times 100[/tex]

                                                               = 77.8

                                                               ≈ 78%

Therefore, his collection increased by 78%.

Is the triangle with sides 9, 12, 14 acute, right or obtuse

Answers

Answer: Acute

Step-by-step explanation: An acute triangle has three angles that each measure less than 90 degrees. An obtuse triangle is a triangle with one angle that is greater than 90 degrees. A right triangle is a triangle with one 90 degree angle.

Acute triangle, because if you draw out the triangle with the given lengths, each angle will be less than 90, which means it's an acute triangle.

fruit: vegetables =9:8
hassan receives total of $5765 from selling fruits and vegetables. how much did he receive from selling fruits and vegetables each.

-hassan sold oranges at $0.35 per kg .if he reduced the price for 40%. what is new price of oranges per kilograms.

- the sale price of oranges $0.35 was increased of 25% from the previous price ,calculate previous day price .

hlp plzzzzzzzzzzzzz ​

Answers

Answer:

950kg

Fruits = 3052.06

vegetables = 2712.94

$0.12

$0.44

Step-by-step explanation:

The first step is to determine the total tonnes of fruits and vegetables sold

7/12 x b = 2.28

b = 2.28 tonnes

Next we determine the tonnes of fruits sold

5/12 x 2.28 = 0.95 tonnes

Next we convert tonnes to kg

1 tonne = 1000kg

0.95 x 1000 = 950 kg

Money he received from selling fruits = 9/17 x $5765 = $3052.06

Money he received from selling vegetables = $5765 - $3052.06 = $2712.94

If price was reduced by 40%, price would be (100-40%) 60% of the original price

0.6 x 0.35 = $0.21

If price was increased by 25%, price would be (100 + 25) 125% of the original price

1.25 x 0.35 = $0.44

In this exercise we have to use the knowledge of finance and percentage to calculate the values ​​of vegetables and fruits:

A)[tex]950\ kg[/tex]

B)Fruits: [tex]\$ 3052.06[/tex] and Vegetables: [tex]\$ 2712.94[/tex]

C)[tex]\$0.12[/tex]

D)[tex]\$0.44[/tex]

The first step is to determine the total tonnes of fruits and vegetables sold:

[tex](7/12)*( b )= 2.28\\b = 2.28\ tonnes[/tex]

Next we determine the tonnes of fruits sold:

[tex](5/12)*( 2.28) = 0.95 \ tonnes[/tex]

Next we convert tonnes to kg:

[tex]1 \ tonne = 1000 \ kg\\(0.95)*( 1000) = 950\ kg[/tex]

Money he received from selling fruits: [tex](9/17)*(5765) = \$3052.06[/tex] Money he received from selling vegetables: [tex]5765 - 3052.06 = \$2712.94[/tex]

If price was reduced by 40%, price would be 60% of the original price, so:

[tex](0.6)*(0.35) = \$0.21[/tex]

If price was increased by 25%, price would be 125% of the original price, will be:  

[tex](1.25)*(0.35) = \$0.44[/tex]

What is the common difference and ninth term for the following sequence:

The sequence can be written like this,

Here the common difference is clearly -0.5 or [tex]-\frac{1}{2}[/tex], and we can conclude that [tex]n^{th}[/tex] number is [tex]3 - 0.5(n-1)[/tex]. So the 9th term is,
