A grocer has 18 kg of black tea worth $3.5 per kg. She wants to mix it with green tea worth $2.6 per kg to sell the mixture at $2.9 per kg. How much of green tea should she use?
Answer:
36
Step-by-step explanation:
Let the weight of the green tea used be x kg.
From the question:
We have:
18 kg of black tea at $ 3.5 per kg. Thus total cost of black tea is 18 x 3.5 = $ 63
Cost of green tea is $2.6 per kg. Total cost of green tea is 2.6 * x = $2.6x
Total weight of the mixture is 18 + x kg.
Total cost of the mixture is = $2.9 (18 + x)
Thus,
Total cost of black tea + total cost of green tea = Total cost of the mixture
$63 + $2.6 x = $2.9 (18 + x)
$63 + $2.6x = $52.2 + $2.9x
63 – 52.2 = 0.3 x
10.8 = 0.3 x
x = 10.8/0.3
x = 36
36 kg of green tea is needed
The ratio of the numerator to the denominator of a fraction is 2 to 3. If both the numerator and the denominator are increased by 2, the fraction becomes . What is the original fraction?
Answer:
a) If both the numerator and the denominator are increased by 2, the fraction becomes?
= 4/5
b) What is the original fraction?
= 2/3
Step-by-step explanation:
The ratio of the numerator to the denominator of a fraction is 2 to 3.
a) If both the numerator and the denominator are increased by 2, the fraction becomes .
2:3 = 2/3
We are told that both numerator and denominator are increased by 2, hence:
2 + 2/3 + 2
= 4/5
b) What is the original fraction?
The ratio of the numerator to the denominator of a fraction is 2 to 3.
Hence, the original fraction is:
2:3 = 2/3

What is the decimal for the fraction 22/4
The decimal for this fraction is 5.5
Answer:
The decimal for the fraction is 5.5.
Step-by-step explanation:
Between 20/4 and 24/4, you can safely assume that the fraction provided is between 5 and 6 which makes part of your answer as a whole number 5. Since 22/4 is exactly between the fractions mentioned above, it is safe to assume that the decimal is 5.5 with .5 being half of the number.
4(3x + 2) =16x + 7 -4x + 1
Answer:
All real numbers are solutions.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4(3x+2)=16x+7−4x+1
(4)(3x)+(4)(2)=16x+7+−4x+1(Distribute)
12x+8=16x+7+−4x+1
12x+8=(16x+−4x)+(7+1)(Combine Like Terms)
12x+8=12x+8
12x+8=12x+8
Step 2: Subtract 12x from both sides.
12x+8−12x=12x+8−12x
8=8
Step 3: Subtract 8 from both sides.
8−8=8−8

which recursive formula can be used to represent the sequence 2,5,8,11,14,..
a. a1=2 an-1=an+3
b. a1=0 an=an-1+3
c. a1=2 an=an-1-3
d. a1=2 an=an-1+3
The recursive formula that is used to represent the sequence 2,5,8,11,14,... is a(n)=a(n-1)+3.
SequenceA sequence is an ordered set of numbers that frequently maintain a pattern.
How to find a recursive formula that is used to represent the given sequence?The given sequence is 2,5,8,11,14,..
The first term is 2.
So, a(1)=2
The common difference is (5-2), that is 3.
So, the recursive formula is a(n)=a(n-1)+3
Therefore, the recursive formula that is used to represent the sequence 2,5,8,11,14,... is a(n)=a(n-1)+3.
Thus, the correct option is (d)

Step-by-step explanation:
if y varies directly as the square if x. If y=27 when x=3, find x when y=81?
Answer:
x = 3[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Given y varies directly as x², then the equation relating them is
y = kx² ← k is the constant of variation
To find k use the condition y = 27 when x = 3 , then
27 = k × 3² = 9k ( divide both sides by 9 )
3 = k
y = 3x² ← equation of variation
When y = 81, then
81 = 3x² ( divide both sides by 3 )
27 = x² ( take the square root of both sides )
x = [tex]\sqrt{27}[/tex] = [tex]\sqrt{9(3)}[/tex] = 3[tex]\sqrt{3}[/tex]

A certain cookie recipe calls for 3 cups of flour to make one batch of cookies. Which
of the following graphs BEST represents the relationship between the amount of
flour and the number of batches of cookies that can be made using this recipe?
Answer:
the answer is the one similar to the one highlighted in purple, but the line should go through the points (3,1), (6,2), (9,3), (12,4)... so on and so forth
Step-by-step explanation:
We want to see which graph represents the relationship between the number of cups of flour and the number of batches of cookies that can be made with the recipe. The graph can be seen at the end.
So, we know that for every 3 cups of flour, we can make 1 batch of flour.
This relation can be written as:
y = (1/3cups)*x
Where y is the number of batches of cookies that you get, and x is the number of cups of flour that you use.
The graph of this line can be seen in the image below:
You can notice that neither of the two shown graphs coincides with this, so the correct option is not shown.

This Diagram Shows a Square (6x-1)cm (4x+6)cm. Find the length of the side of the square. Your final answer must say, Side = ...cm
Given:
Diagram Shows a Square (6x-1)cm (4x+6)cm.
To find:
The length of the side of the square.
Solution:
We know that, all sides of a square are equal. So,
[tex]6x-1=4x+6[/tex]
[tex]6x-4x=1+6[/tex]
[tex]2x=7[/tex]
Divide both sides by 2.
[tex]x=\dfrac{7}{2}[/tex]
[tex]x=3.5[/tex]
Now, the side of the square is
[tex]Side=6x-1[/tex]
[tex]Side=6(3.5)-1[/tex]
[tex]Side=21-1[/tex]
[tex]Side=20\text{ cm}[/tex]
Therefore, the length of the side of the square = 20 cm.
Answer:
Given:

Michael earns $9 per hour. He works 28 hours each week. How much does he earn in 6 weeks?
Answer:
$1, 512
This is how:
1) Michael works 28 hours in one week. So how many hours does he work in 6 weeks?
So you need to calculate : 28 × 6 = 168
SO THIS IS THE TOTAL NUMBER OF HOURS FOR 6 WEEKS.
2) because Michael gets paid $9 PER HOUR :
You will need to multiply the amount of money he receives with the total number of hours he works.
168 × 9 = $ 1, 512
He earns $1,512 in 6 weeks
