Myron is cooking meat. The double number line shows that he needs 1 2 12 hours to cook 5 5 kilograms of meat. 0 0 5 5 Meat Meat (kg) (kg) 0 0 1 2 12 Time Time (hours) (hours) Based on the ratio shown in the double number line, how long does Myron need to cook 3 3 kilograms of meat?
Answers
Answer: 7 hours 12 minutes
Step-by-step explanation:
Let he needs x hours to make 1 kg of meat.
Therefore, time taken in making 5 kg of meat = 5 × x = 5x hours.
But, According to the question,
He needs 12 hour to cook 5 kg of meat.
Thus, 5 x = 12
⇒ [tex]x = \frac{12}{5}[/tex] ( By dividing both sides by 5 )
⇒ He needs [tex] \frac{12}{5}[/tex] hours to make 1 kg of meat.
⇒ The time taken to cook 3 kg of meat = [tex]3\times \frac{12}{5}=\frac{36}{5} [/tex]
= [tex]7\frac{1}{5}[/tex] hours ⇒ 7 hours 12 minutes
Hence, He needs 7 hours 12 minutes time to cook 3 kg of meat.
After calculating, we determined that Myron needs 54 minutes to cook 3 kilograms of meat.
This problem can be solved by setting up a proportion since it involves a direct ratio between the weight of meat and the cooking time.
The given ratio is 1 1⁄2 hours for 5 kilograms of meat (1:5 ratio). To find the time needed for 3 kilograms of meat, use the proportion:
5 kg :- 1 1⁄2 hours
3 kg :- x hours
Solving for x yields the following:
5 kg / 3 kg = 1 1⁄2 hours / x hours
x = (1 1⁄2 hours × 3 kg) / 5 kg
Converting 1 1⁄2 hours to minutes (90 minutes) and then performing the multiplication and division:
x = (90 minutes × 3) / 5
x = 270 minutes / 5
x = 54 minutes
Thus, Myron needs to cook 3 kilograms of meat for 54 minutes.

which equation and ordered pair represent the correct vertex form and vertex for j(x) = x^2 - 12 x +7?
Answers
Answer:
see explanation
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Given the equation in standard form : ax² + bx + c : a ≠ 0
then the x-coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
j(x) = x² - 12x + 7 is in standard form
with a = 1, b = - 12 and c = 7, hence
[tex]x_{vertex}[/tex] = - [tex]\frac{-12}{2}[/tex] = 6
substitute x = 6 into j(x) for y- coordinate
y = 6² - 12(6) + 7 = 36 - 72 + 7 = - 29
vertex = (6, - 29 ) and
j(x) = (x - 6)² - 29 ← equation in vertex form

Jasmine borrowed $15,000 for 8 years and she paid $6,600 in interest. What was the interest rate for Jasmine's loan?
A) .055%
B) 6%
C) 3.25%
D) 5.5%
Answers
Answer:
D) 5.5%
Step-by-step explanation:
To find the interest rate, use the equation: I = prt
I = Interest = $6,600
p = principal = $15,000
r = rate = unknown
t = time = 8 years
Now plug the numbers into the equation.
6,600 = 15,000 * r * 8
6,600 = 120,000 * r
Now isolate the variable by dividing both sides of the equation by 120,000.
0.055 = r
Now change the rate to a percent by moving the decimal point 2 digits to the right.
5.5% = r OR r = 5.5%

finding the number of equal-sized parts into which a number can be split
finding the combined value of several different number
finding the distance between two numbers on a number line
finding the total value when several of the same number are grouped together
Answers
Answer:
finding the number of equal-sized parts into which a number can be split
Step-by-step explanation:
Let us split the number 80 into 10 equal parts.
80 = 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8
= 8 + 8 + 8 +...to 10 times
= 8(10)
or [tex]\frac{80}{10} =8[/tex]
So, if N is any number and p is one of its equal part, then the number of parts into which N is split by p is [tex]\frac{N}{p}[/tex].
Hence, finding the number of equal-sized parts is best modeled with a division expression.
Answer:

Alana earnerd money doing chores. Her grandmother agreed to add $4.00 to the amount Alana earned and then give her half of that sum. Alana's grandmother gave her gave her $4.25. Write and solve an equation to find the amount of Alana's donation
Answers
Answer:
Hence amount of Alana's donation is $4.5.
Step-by-step explanation:
Amount of Alana's donation = x
Her grandmother agreed to add $4.00 to the amount Alana earned.
So new amount of money = (x+4)
She gives only half of the sum which is (x+4)/2.
She gave her $4.25 so both values must be equal.
[tex]\frac{\left(x+4\right)}{2}=4.25[/tex]
[tex]x+4=4.25*2[/tex]
[tex]x+4=8.5[/tex]
[tex]x=8.5-4[/tex]
[tex]x=4.5[/tex]
Hence amount of Alana's donation is $4.5.
Alana earned $4.50 from doing chores before her grandmother added an additional $4.00 and then gave her half of the total, which was $4.25.
The question relates to finding out how much money Alana earned by doing chores before her grandmother added $4.00 and then gave her half. In this scenario, we let x represent the amount of money that Alana earned from doing chores. According to the information provided, Alana's grandmother agreed to add $4.00 to Alana's earnings and then give her half of the total sum. This can be expressed as:
(x + 4.00) / 2 = 4.25
To solve for x, we first multiply both sides of the equation by 2 to get rid of the denominator:
x + 4.00 = 4.25 * 2
x + 4.00 = 8.50
Next, we subtract $4.00 from both sides of the equation to solve for x:
x = 8.50 - 4.00
x = 4.50
Therefore, the amount of money Alana earned from doing chores is $4.50.

Given the regular decagon (10-sided polygon), which statements are true?
Choose all that apply
A. The polygon has 90° rotational symmetry
B. The polygon has 36° rotational symmetry
C. The polygon has 144° rotational symmetry
D. The polygon has point symmetry
Answers
The regular decagon has 36° rotational symmetry and point symmetry because it can map onto itself by rotating 36° and when flipped 180° around its center.
Explanation:The subject of the question is a regular decagon, which is a 10-sided polygon.
To find out which statements are true regarding its symmetry, consider that rotational symmetry of a polygon is determined by the angle of rotation that maps the polygon back onto itself without altering its general outline.
For a regular decagon, the angle of rotation that achieves this is 360 degrees divided by the number of sides, which is 10 in this case.
Therefore, the correct angle of rotational symmetry is 360/10 = 36 degrees.
Thus, the correct answer from the provided options is:

A candy mixture is made from 6 pounds of sugar sticks of $10 per pound and 14 pounds of jelly beans of $8 per pound. Find the price of the candy mixture per pound.
Answers
14 × 8 = 112$ per 14 pounds
you'll get 20 pounds of the candy mixture and will cost 172
172/20
8.6$ per pound
Final answer:
The price of the candy mixture per pound is $8.60.
Explanation:
To find the price of the candy mixture per pound, we need to calculate the total cost of the sugar sticks and jelly beans, and then divide it by the total weight of the candy mixture.
Let's start by calculating the total cost of the sugar sticks. The cost per pound of sugar sticks is $10, and we have 6 pounds of sugar sticks, so the total cost of the sugar sticks is 6 x $10 = $60.
Next, let's calculate the total cost of the jelly beans. The cost per pound of jelly beans is $8, and we have 14 pounds of jelly beans, so the total cost of the jelly beans is 14 x $8 = $112.
Now, let's calculate the total weight of the candy mixture. We have 6 pounds of sugar sticks and 14 pounds of jelly beans, so the total weight of the candy mixture is 6 + 14 = 20 pounds.
Finally, let's calculate the price of the candy mixture per pound. We divide the total cost of the candy mixture by the total weight of the candy mixture: ($60 + $112) / 20 = $172 / 20 = $8.60.
Therefore, the price of the candy mixture per pound is $8.60.
