Answer:
x^2 -4x -21
Step-by-step explanation:
Here, we want to write a quadratic polynomial
We have the sum as -4
Let us have x as the variable
so the sum of the variables is -4x
while the product is -21 x^2
Two factors of 21 that can work here is -7x and 3x
So we have
x^2 - 7x + 3x -21
= x^2 -4x -21
Miguel has a garden that has an area of 300 square feet. If the corn in his garden covers 160 square feet, what percent of the garden is corn?
Im not sure of my answer but I got 5.33 and the 3 repeats
Answer:
Im sorry if I'm wrong but I think it's 300+160=460
Answer:
yes your correct but wrong
Step-by-step explanation:
To find the area that's covered in corn you need to first write your fraction.
160/300
After you do that you have to turn it into a decimal.
.53333...
After that you need to turn it into a percent so your final answer will be....
53.333...%
BTW try looking to see if you need to round, normally it tells you to do that
Hassan sells fruits and vegetables at the market
- the mass of fruit and vegetables are in the ratio. fruit: vegetables =5:7
if hassan sells 1.33 tones of vegetables how many kilograms of fruits did he sell?
- the amount of money hassan receive from selling fruits and vegetables is in the ratio .
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
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]

2. P= 7in A= 12 in
3. P= 18cm A= 81cm
Step-by-step explanation: For the P or Perimeter you need to add both of the numbers around the box. For A or the area you need to multiply the numbers on the box. You can also find that in the reading above the problem.

What is the value of 19-7-15+14
Answer: the answer is 11 :)
Step-by-step explanation: I hope this helped!
Answer:
11
Step-by-step explanation:
19 - 7 = 12 - 15 = -3 + 14 = 11
or, if your brain likes it better, add the positives, then add the negatives, then subtract:
19 + 14 = 33
-7 -15 = -22
33 - 22 = 11
What is the common difference and ninth term for the following sequence:
3,5/2,2,3/2,1
Answer:
Common Difference: [tex]-\frac{1}{2}[/tex]
The ninth term: -1
Step-by-step explanation:
The sequence can be written like this,
3, 2.5, 2, 1.5, 1, ....
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,
[tex]3 - 0.5(9 - 1)\\= -1[/tex]
