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

2. Given A=15°, b=8, and a=6, use the Law of Sines to solve the triangle (if possible)
for the value of c. If two solutions exist, find both. Round answer to two decimal places.
A) c=11.01
B) c=2.10 and 13.36
C) c=12.14
D= c=1.12 and 10.24
E) not possible
Answer:
B
Step-by-step explanation:
The Law of Sines states that
sinA/a = sinB/b = sinC/c
We know A, a, and b. Given this, we can solve for B, and given that, we can solve for C and then c.
First, we solve for B.
sinA/a = sinB/b
sin(15°)/6 = sinB/8
sin(15°)/6 * 8 = sinB
arcsin(sin(15°)/6 * 8) = B ≈ 20.187
Note that there can be a second B value. We can check if there is a second B value by first subtracting the B value we got from 180.
180 - 20.187 = 159.813
Next, we can add that to our existing angle, A = 15°. If that is less than 180, then we do have a second solution. 159.813 + 15 = 174.813 < 180 so there does exist a second solution where B = 159.813
Next, we can solve for C.
We know that the angles in a triangle add to 180°, so A + B + C = 180. Therefore, for the first solution:
15 + 20.187 + C = 180
C = 180 - 15 - 20.187 = 144.813°
and for the second:
15 + 159.813 + C = 180
C = 180 - 15 - 159.813 = 5.187
Finally,
sinA/a = sinC/c
multiply both sides by c to no longer have it as a denominator
sinA * c / a = sinC
divide both sides by (sinA/a) to isolate c
for the first solution:
c = sinC*a/sinA = 13.35868 ≈ 13.36
and for the second:
c = sinC*a/sinA ≈ 2.10
The radius of a circle is 16 millimeters. What is the circle's area?
Use 3.14 for .
please answer windowesssssssssssssss
Answer:
803.84 millimeters²
Step-by-step explanation:
How do we find the area of a circle?
The area of a circle is πr², where r = radius. In this case, we have to approximate pi to 3.14.Solving
[tex]3.14 *16^2[/tex] [tex]3.14*256[/tex] [tex]803.84[/tex]Therefore, the area is 803.84 square millimeters.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Solution:
We know that:
Radius = r = 16 mmArea of circle = (π)(r²)Finding the area of the circle:
Area of circle = (3.14)(16²)=> Area of circle = 3.14 x 16²=> Area of circle = 3.14 x 256=> Area of circle = 803.84 mm²Daina gives 2/3 of his money to Carol. Carol gives 6/7 of this money to Zak.

Answer:
x = 29°, y = 61°
Step-by-step explanation:
x + 61 = 90
Because of the right angle symbol
x = 90 - 61
x = 29°
x + y = 90
Because vertically opposite angles are equal
29 + y = 90
y = 90 - 29
y = 61°

Answer: m<D = 30
Step-by-step explanation: In the third step of the problem, it says that E is next to itself and equals 90. However, this is not true. Angle BEA and angle CED are vertical angles and are both equal to 65°. This means that to find the measurement of angle D, subtract 65 and 85 from 180, which equals 30.

William has scored a total of 235 points on the first three math tests taken in his mathematics class. If his mathematics test are always worth 100 points, how many points must he earn on his next test in order to have an average of 80%
Answer:
85 points
Step-by-step explanation:
His total points will be 235+x
Number of tests will be 4
(235+x)/4 = 80
multiply by 4
235+x= 4*80
235+x= 320
x=320-235
x= 85
He has to get 85 points to average 80

At a shelter 15% of the dogs are puppies there are 60 dogs at the shelter. How many are puppies?
Explanation:
One method is to do the steps like this
15% of 60 = 0.15*60 = 9
Or you can solve like this
part/whole = percent/100
x/60 = 15/100
100x = 60*15
100x = 900
x = 900/100
x = 9
