On Saturday 4 groups of people went to the restaurant at the ski resort. Each group had 5 people in it. Everyone ordered a cup of hot chocolate. Rebecca,Malaki,and Jeffery each ordered an extra cups of hot chocolate.how many many cups of chocolate did the people drink that day?
Answer:
23
Step-by-step explanation:
total number of people at the restaurant = number of groups x total number of people in the groups
4 x 5 = 20
20 people ordered hot chocolate
3 people ordered an extra cup of hot chocolate.
The total number of hot chocolate ordered = 20 + 3 = 23

9) Use a proportion with words and numbers to determine how many hours this person would have to work to have an income of $1000.
Plz solve correctly and solve all questions you will get 24 points plus brainliest.
Answer:
Step-by-step explanation:
6. 13/hour
7. R=income/hours worked so 221/17=13. Not sure if that is what they are asking for.
8. Not sure. Is it $13/hour?
9. still guessing but the constant is $13/hour so to determine how many hours need to be worked to reach $1000, you divide. $1000/13=Approximately 77 hours.

A farmer has 500 acres of arable land on which he wants to plant potatoes and corn. The farmer has $40,000 available for planting and $30,000 for fertilizer. Planting 1 acre of potatoes costs $90, and planting 1 acre of corn costs $50. Fertilizer costs $30 for 1 acre of potatoes and $80 for 1 acre of corn. (a) Find a system of inequalities that describes the number of acres of each crop that the farmer can plant with the available resources. (Let x and y be the numbers of acres of potatoes and corn, respectively.)
Answer:
90x+ 50 y ≤ $40,000------ A
30x+ 80y ≤ $ 30,000------- B
x + y ≤ 500 --- C
Step-by-step explanation:
Let x and y be the numbers of acres of potatoes and corn, respectively.
Then according to the given conditions
90x+ 50 y ≤ $40,000------ A
30x+ 80y ≤ $ 30,000------- B
x + y ≤ 500 --- C
where both x and y equal to or greater than zero and cannot take a value less than zero.
x + y ≤ 500 --- C
gives us an idea that the total arable land is less or equal to 500 acres.
90x+ 50 y ≤ $40,000------ A
tells us that the total cost of planting potatoes and corn is less or equal to $ 40,000
30x+ 80y ≤ $ 30,000------- B
tells us that the total cost of fertilizers for potatoes and corn is less or equal to $ 30,000
In each of these x and y cannot have negative values or less than zero.

Step-by-step explanation:
Ian is borrowing $1000 from his parents to buy a notebook computer. He plans to pay them back at the rate of $60
per month. Ken is borrowing $600 from his parents to purchase a snowboard. He plans to pay his parents back at
the rate of $20 per month. a) Write an equation that can be used to determine after how many months the boys will owe the same amount.
b) Determine algebraically and state in how many months the two boys will owe the same amount. State the
amount they will owe at this time.
c) Ian claims that he will have his loan paid off 6 months after he and Ken owe the same amount. Determine and
state if Ian is correct. Explain your reasoning.
A = 10 months
B = First part, the two equations:
Ian: y = 1000 - 60x, where x is the number of months and y is the remaining balance owed.
Ken: y = 600 - 20x.
They will be equal at 1000 - 60x = 600 - 20x
Second part: Solve the equation. Note, if you're equation is incorrect, solve it anyway because you will still get some credit!
1000 - 60x = 600 - 20x
1000 = 600 + 40x
400 = 40x
x = 10 months
y = 600 - 20(10) = 600 - 200 = $400 still owed.
C =
Solve Ian's equation for y = 0, when no money is owed.
1000 - 60x = 0
1000 = 60x
x = 16.66666.... or 17 months.
Ian will not be paid off 6 months after he and Ken owe the same amount. He will still owe money.
Alternatively, six months after 10 is 16 months,
and y = 1000 - 60(16) = 1000 - 960 = 40. He will still owe $40 at 16 months, so he is not paid off.

16. A radioactive isotope has a half-life of 13 hours. Find the amount of the isotope left from a 400-milligram
sample after 65 hours. If necessary, round your answer to the nearest thousandth.
a. 25 mg
c. 0.049 mg
b. 7.692 mg
d. 12.5 mg
Please help. I only see answers for 52 hours
Answer:
Without the math: 65 hours is 5 half-lives
13 hrs = 1/2
26 hrs = 1/4
39 hrs = 1/8
65 hrs = 1/32
(1/2)^5 = 1/32
400 mg / 32 = 12.5 mg that is, after 5 half-lives

Answer:
[tex]x=96[/tex]
Step-by-step explanation:
[tex]360=x+\left(x+90\right)+\left(x-18\right)[/tex]
Step 1: Simplify both sides of the equation.
[tex]360=x+x+90+x-18[/tex]
[tex]360=(x+x+x)+(90+-18)[/tex] (Combine Like Terms)
[tex]360=3x+72[/tex]
Step 2: Flip the equation.
[tex]3x+72=360[/tex]
Step 3: Subtract 72 from both sides.
[tex]3x+72-72=360-72[/tex]
[tex]3x=288[/tex]
Step 4: Divide both sides by 3.
[tex]\frac{3x}{3}=\frac{28}{3}[/tex]
[tex]x=96[/tex]

Round to the nearest tenth. Use 3.14 or 22/7 for π.
Note: Consider we need to find the circumference and area of the given circle.
Given:
A circle with radius 7.1 m.
To find:
The circumference and area of the given circle.
Solution:
Circumference of a circle is:
[tex]C=2\pi r[/tex]
Putting [tex]r=7.1,\pi=3.14[/tex], we get
[tex]C=2(3.14)(7.1)[/tex]
[tex]C=44.588[/tex]
[tex]C\approx 44.6[/tex]
Therefore, the circumference of the circle is 44.6 m.
The area of the circle is:
[tex]A=\pi r^2[/tex]
Putting [tex]r=7.1,\pi=3.14[/tex], we get
[tex]A=3.14(7.1)^2[/tex]
[tex]A=158.2874[/tex]
[tex]A\approx 158.3[/tex]
Therefore, the area of the circle is 158.3 sq. m.

Which reflection will produce an image of ARST with a
vertex at (2, -3)?
O a reflection of ARST across the x-axis
O a reflection of ARST across the y-axis
O a reflection of ARST across the line y = x
O a reflection of ARST across the line y=-x
Answer: D- a reflection of ^RST across the line y=-x
Step-by-step explanation:
The solution is, O a reflection of RST across the line y=-x, is the reflection which will produce an image of RST with a vertex at (2, -3).
What is reflection?Reflection is a type of transformation that flips a shape in a mirror line (also called a line of reflection) so that each point is the same distance from the mirror line as its reflected point.
here, we have,
from the given figure,
we get,
Triangle RST has,
vertex R ( -1,3)
vertex S ( 3, -2)
vertex t (1, -4)
now we know that,
the rule of a reflection across the line y=-x,
(x, y) ⇒ (-x, -y)
so, we get, here,
vertex S ( 3, -2) ⇒ vertex at (2, -3)
so, there is O a reflection of RST across the line y=-x.

The measure of angle ABC by the given data is 57 degrees.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
∠ABD=70∘
Now,
To find the measure of angle ABC, we need to use the fact that the sum of the angles in a triangle is 180 degrees. We can write an equation using this fact and the given information:
m∠ABD + m∠CBD + m∠ABC = 180 70 + (5x + 13) + (3x + 33) = 180
To solve for x, we need to simplify and isolate it by performing the inverse operations on both sides. We can do this by following these steps:
Step 1: Combine like terms on both sides of the equation.
70 + 5x + 13 + 3x + 33 = 180 8x + 116 = 180
Step 2: Subtract 116 from both sides of the equation.
8x + 116 - 116 = 180 - 116 8x = 64
Step 3: Divide both sides by 8 to get x by itself.
8x / 8 = 64 / 8 x = 8
Now that we have the value of x, we can plug it into the expression for m∠ABC and simplify:
m∠ABC = 3x + 33 m∠ABC
= 3(8) + 33 m∠ABC
= 24 + 33 m∠ABC = 57
Therefore, by algebra the answer will be 57 degrees.
