(i)Write TWO inequalities which satisfy these conditions.
(ii) She buys no more than 60 kg of nuts. Peanuts cost $4.00 per kg and cashew nuts cost $8.00 per kg and she spends at least $200.
Write Two inequalities which satisfy these conditions.
Answers
The inequalities that satisfy this condition is 4x + 8y ≥ 200 and x + y ≤ 60
What is an inequality?
An inequality is an expression that shows the non equal comparison between two or more numbers and variables.
Let x represent the number of peanuts and y represent the number of cashew nuts.
She must buy a minimum of 10 kg of peanuts and a minimum of 5 kg of cashew nuts. Hence:
x ≥ 10, y ≥5
Also:
x + y ≤ 60
And:
4x + 8y ≥ 200
The inequalities that satisfy this condition is 4x + 8y ≥ 200 and x + y ≤ 60

Is it right??
Answers
Answer:
28.5 units²
Step-by-step explanation:
You are correct.
You divided the figure into a square, a rectangle and a triangle.
You can also just divide into a rectangle and a triangle as I did below, and there are other ways of dividing the figure to find the area.
Bottom rectangle: 8 units by 3 units
Top triangle: base = height = 3 units
total area = area of rectangle + area of triangle
total area = length × width + base × height / 2
total area = 8 units × 3 units + 3 units × 3 units / 2
total area = 24 units² + 4.5 units²
total area = 28.5 units²

Step-by-step explanation:2x=16 divide 2 on both, x=8, plug in 8 for x, -1x8-3y=4 will become = -8-3y=4 add 8 on both sides and divide by -3 the answer will be -4
Answer:
Step-by-step explanation:-
-1x - 3y = 4 (eqn 1)
2x = 16 (eqn 2)
from eqn 2
2x = 16
x = 16/2
x = 8
Substitute x = 8 into eqn 1
-1(8) - 3y = 4
-8 - 3y = 4
-3y = 4 + 8
-3y = 12
y = 12/-3
y = -4
therefore, x = 8 and y = -4

What is the distance between (4, −3) and (9, −3) ? Enter your answer in the box.
Answers
Answer:
5 units
Step-by-step explanation:
Luckily, we don't need to use the distance formula as we just need to find the distance between the x-coordinates. Thus, |4-9| = |-5| = 5, which means that the distance between (4,-3) and (9,-3) is 5 units
Answer:
5
Step-by-step explanation:
Point (4, -3) and point (9, -3) have the same y-coordinate of -3. Therefore, both points are on the line y = -3.
Any line that is y = {number} is a horizontal line.
Therefore, to find the distance between the points, find the difference between the x-values:
9 - 4 = 5
Therefore, the distance between (4, −3) and (9, −3) is 5

Step-by-step explanation:
All triangles without exception, have 3 angles that add to 180o.
You know two of them. The statement above will help you get the third.
35 + 33 + x = 180 Combine the left
68 + x = 180 Subtract 68 from both sides.
x = 180 - 68
x = 112
Answer: The value of x is 112
Step-by-step explanation:
add the two values given: 35+33= 68
then subtract 68 from 180 (sum of angles is 180°) = 112
112+35+33= 180
When you measure an angle you usually have to choose between two numbers because
protractors are designed to measure angles that start on either the right or left side.

Blue 22
Green 19
Purple 20
Red 18
Yellow 21
If Song were to repeat the experiment 25 more times, how many of those times should he expect to pull a purple marble?
Enter your answer as a number, like this: 42
Answers
Step-by-step explanation:
when counting the events we see, he did
22+19+20+18+21 = 100 experiments.
and he got in 20 cases out of the possible 100 a purple marble.
that means the observed probability to pull a purple marble is 20/100 = 1/5.
now he does 25 more pulls.
each with the probity of 1/5 to pull a purple marble.
so, he should expect to pull a purple marble 25×1/5 = 5 times.

For a standard normal distribution, the approximate value of p
( z≥-1.25 ) is 0.8945.
What is a standard normal distribution?The standard normal distribution is a normal distribution with a mean of zero and a standard deviation of 1. The standard normal distribution is centered at zero and the degree to which a given measurement deviates from the mean is given by the standard deviation.
As we know that Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.
It is given that z-score≥-1.25
From the standard normal table, the p-value corresponding to z≥-1.25 is
0.8945.
Therefore, For a standard normal distribution, the approximate value of p ( z≥-1.25 ) is 0.8945.

Peter can mow his lawn in 6 minutes. Peter's son can mow it in 8 minutes. How long will it take them to do it together?
Answers
Answer:
3 minutes 26 seconds
Step-by-step explanation:
rate x time in Distance problems, and W = rate x time in work problems. The Work is generally 1, the whole job.
For Peter the formula is 1 (lawn mowed) = 1/6 lawn per minute x 6 minutes.
For the son the formula is 1 = 1/8 * 8.
Add their rates together, 1/8 + 1/6 = 3/24 + 4/24 = 7/24.
The equation for their rate working together is 1 = 7/24 * t
Divide both sides by 7/24 to find t. t = 1 / 7/24 = 1 * 24/7 = 24/7 = 3 and 3/7 minutes = approx. 3 minutes 26 seconds.

the 8th term of an arithmetic sequence is -42 and the 16th term is -74. Find and simplify an expression for the nth term
Answers
Answer:
[tex]a_{n}[/tex] = - 4n - 10
Step-by-step explanation:
the nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
given a₈ = - 42 and a₁₆ = - 74 , then
a₁ + 7d = - 42 → (1)
a₁ + 15d = - 74 → (2)
subtract (1) from (2) term by term to eliminate a₁
8d = - 74 - (- 42) = - 74 + 42 = - 32 ( divide both sides by 8 )
d = - 4
substitute d = - 4 into (1) and solve for a₁
a₁ + 7(- 4) = - 42
a₁ - 28 = - 42 ( add 28 to both sides )
a₁ = - 14
Then
[tex]a_{n}[/tex] = - 14 - 4(n - 1) = - 14 - 4n + 4 = - 4n - 10
Answer:
[tex]a_{n}=-10-4n[/tex]
Step-by-step explanation
[tex]a_{n}=a_{1}+(n-1)d\\Given:a_{8}=-42\\&a_{16}=-74\\Hence: \\a_{8}=a_{1}+7d=-42 (1)a_{16}=a_{1}+15d=-74 (2)\\ \left \{ {{a_{1}+7d=-42} \atop a_{1}+15=-74}} \right. \\(2)-(1):8d=-32\\ d=-32/8 =-4\\Substitute :d=-4 in equation (1)"\\-42=a_{1}+7(-4)\\-42=a_{1}-28\\a_{1}=-14\\Hence:\\a_{n}=-14-(n-1)4\\a_{n}=-14-4n+4\\a_{n}=-10-4n[/tex]
