Answer: No, it is not enough to make 2 batches of Mac and cheese and 3 pizzas.
Step-by-step explanation:
Since we have given that
She needed 6 ounces of cheese and 2 tablespoons of basil for each batch of her Mac and cheese.
Now,
For every two pizzas she needed 16 ounces of cheese and 5 tablespoons of basil.
So, for 2 batches of Mac and cheese she needed = 12 ounces of cheese
and if for 2 pizzas she needed = 16 ounces of cheese
For 1 pizza she needed = 8 ounces of cheese
For 3 pizza she needed = 8× 3=24 ounces of cheese
Total requirement of cheese = 24+ 12=36 ounces
But she only buys 32 ounces package of cheese .
So, it is not enough to make 2 batches of Mac and cheese and 3 pizzas and 4 ounces is still needed i.e.
36-32 =4 ounces .
Lena bought a 32 oz package of cheese, and since 60 ounces is greater than 32 ounces, she does not have enough cheese to make 2 batches of Mac and cheese and 3 pizzas with her current supply.
What is the cheese recipeIf Lena has enough cheese to make 2 batches of Mac and cheese and 3 pizzas.
Each batch of Mac and cheese requires 6 ounces of cheese, and she wants to make 2 batches,
so that's 6 ounces * 2
= 12
Each pizza requires 16 ounces of cheese, and she wants to make 3 pizzas,
so that's 16 ounces * 3
= 48
In total, for the Mac and cheese and the pizzas,
Lena needs 12 ounces + 48 ounces
= 60 ounces of cheese.

Angle JKL
is a straight angle.
The measure of angle JKM is 120 degrees.
The measure of angle MKL is X degrees
What is the value of X?
The value for X, the measure of angle MKL, is not specifically given in the question. Since angle JKL is a straight angle of 180 degrees, X can be any value up to 180 degrees.
Explanation:In mathematics, a straight angle is defined as an angle of 180 degrees. In the scenario described with angle JKL, it is mentioned that this is a straight angle. Given that angle MKL is a part of the straight angle, its degree measure X is a component of those 180 degrees. The specific value of X is not given in the question, and it can be any number less than or equal to 180, provided the other part of the angle KJM is equal to 180- X.

The measure of angle MKL is 60 degrees.
Finding the Measure of Angle MKL
To determine the value of X in this problem, we first need to understand that a straight angle measures 180 degrees. The problem states that angle JKL is a straight angle, so:
Angle JKL = 180 degrees
Next, we have the measure of angle JKM given as 120 degrees. Since angle JKL is made up of angle JKM and angle MKL, we can set up the following equation to find the measure of angle MKL, which is X:
Angle JKM + Angle MKL = Angle JKL
Substituting the known values:
120 degrees + X = 180 degrees
To find X, subtract 120 degrees from both sides:
X = 180 degrees - 120 degrees = 60 degrees
Therefore, the measure of angle MKL is 60 degrees.

Answer: -1 1/8
Step-by-step explanation: When you have a problem like this, you have to divide.
So you turn the improper fraction into a mixed number which (4 1/2 turns into 9/2) and then you do KCF (Keep Change Flip). So you keep the 9/8, change division into multiplication, and since we are going to put the four over a 1 like this 4/1, we need to change it into 1/4. Then you multiply across. 9x1=9 and 2x4=8 so it would be 9/8. But it's an improper fraction right? So you do long division, and you get -1 1/8.
You have also set up a card game in which a player picks a card from a standard deck of 52 cards. The player wins if these two events occur together: E1, in which the card drawn is a black card, and E2, in which the card drawn is a numbered card, 2 through 10.What is the probability of getting a black card and a numbered card? Calculate the probabilities P(E1) and P(E2) as fractions.
First, let's count:
there are 26 possible outcomes for E1 (black card)
there are 4x9 = 36 possible outcomes for E2, to pick a numbered card (any color)
there are 2x9 =18 possible outcomes for E1 (black) AND E2 (numbered, spade + clower)
the probability of E1 AND E2 is the ratio of the count of possible outcomes for E1 + E2 and the count of all possible outcomes (52 choices to pick a card from the deck):
P(E1 and E2) = 18/52 (34.6%)
And as asked:
P(E1) = 26/52 = 1/2 (50%)
P(E2) = 36/52 = 9/13 (69.2%)

Given: ΔABC, AB ≅ BC, BE − median of ΔABC, m∠ABE = 40°30' Find: m∠ABC, m∠FEC
Answer:
Given: A Δ ABC in which , AB ≅ BC, BE − median of ΔABC, m∠ABE = 40°30'
To Find: ∠ABC, ∠ CE B,∠A E B
Solution: In Δ ABC , BE is the median.
So, AE= EC
Now, In Δ A E B and Δ CE B
AE = EC [ BE is median]
BE is common.
AB=BC [given]
Δ A E B ≅Δ CE B { SSS Congruency]⇒S→side
So, ∠ABE=∠C BE [ C PCT]
∴ ∠ABC=2×∠ABE=2×40°30'=81°
∠B EA =∠C E B [ C P CT]
Also,∠B A C = ∠BC A=k° [As AB =BC , if opposite sides are equal , then angle opposite to them are equal]
∠A+ ∠B+∠C=180°[ angle sum property of triangle]
k°+81°+k°=180°
2 k°=180°-81°
2 k°=99°
k°=99°/2
k°=49°30'[1°=60']
In Δ A E B, ∠ABE=40°30',∠A=49°30',∠A E B=?
∠ABE+∠A+∠A E B=180°[ angle sum property of triangle]
40°30'+49°30'+∠A E B=180°
90°+∠A E B=180°
∠A E B=180°-90°
∠A E B=90°
As, ∠B EA =∠C E B
So,∠C E B= 90°
So, BE is perpendicular bisector.
The measure of the angle ∠ABC and ∠BCA are both 69°45'. and ∠FEC measures 99°.
How to find the angles?∠ABE and ∠BEC are opposite angles formed by the intersecting lines AB and BE, and BC and BE respectively.
Therefore, they are congruent.
The sum of the interior angles of a triangle is always 180°. So, we can find ∠ABE by subtracting ∠BEC from 180°.
Since m∠ABE = 40°30', we have:
∠BEC = ∠ABE = 40°30'
Since AB ≅ BC, the two sides are congruent.
This means that ∠ABC and ∠BCA are also congruent angles. Let's call their measure x.
Using the fact that the sum of the angles in a triangle is 180°, we can set up an equation:
∠ABC + ∠BCA + ∠BAC = 180°
Since ∠BCA = ∠ABC = x, we can substitute these values in:
x + x + 40°30' = 180°
Adding the like terms:
2x + 40°30' = 180°
Subtracting 40°30' from both sides:
2x = 180° - 40°30'
2x = 139°30'
Dividing both sides by 2:
x = 69°45'
So, ∠ABC and ∠BCA are both 69°45'.
To find ∠FEC, we can use the fact that the sum of the angles in a triangle is 180°. Since ∠BEC = ∠ABE = 40°30', we can find ∠FEC:
∠FEC = 180° - ∠BEC - ∠BCE
Substituting the values we know:
∠FEC = 180° - 40°30' - 40°30'
Simplifying:
∠FEC = 180° - 81°
∠FEC = 99°
Therefore, ∠FEC measures 99°.

A theater can seat 550 people. The number of rows is 3 less than the number of seats in each row. How many rows of seats are there?
The number of rows will be a divisor of 550 such that the quotient is 3 more.
... 550 = 1×550 = 2×275 ≈ 5×110 = 10×55 = 11×50 = 22×25
Factors 22 and 25 differ by 3.
The number of rows of seats is 22.
_____
The number of seats in a row is 25.
The theater has 22 rows of seats. To find this, we solve the equation x(x - 3) = 550, where x is the number of seats per row, leading to x = 25 seats per row and 22 rows after subtracting 3.
To find out how many rows of seats are in the theater with a seating capacity of 550, where the number of rows is 3 less than the number of seats in each row, we can set up an equation to solve for the number of rows. Let the number of seats per row be represented by x, and the number of rows will then be x - 3. Since the total number of seats in the theater is the product of the number of rows and the number of seats per row, we have the equation x(x - 3) = 550.
Now, we will factor this quadratic equation to find the value of x.:
x² - 3x - 550 = 0
Factoring this, we find that it breaks down into (x - 25)(x + 22) = 0. We can then find the value of x by setting each factor equal to zero:
x - 25 = 0: x = 25x + 22 = 0: x = -22 (negative values are not feasible for number of seats)We ignore the negative solution since we cannot have a negative number of seats. Hence, there are 25 seats in each row. To find the number of rows, we subtract 3 from the number of seats per row: 25 - 3 = 22 rows.
Therefore, the theater has 22 rows of seats.

The subscription to a popular magazine decreased from $66 per year to $52.80 per year. What is the percent of decrease for the magazine's subscription?
Final answer:
The percent of decrease for the magazine's subscription is 20%.
Explanation:
To find the percent of decrease for the magazine's subscription, we need to calculate the difference between the original price and the new price, and then divide it by the original price.
The decrease in price is $66 - $52.80 = $13.20.
The percent of decrease is ($13.20 / $66) * 100% = 20%.

−4x − 32 + 25 ≤ −2 + 1x − 50
−4x − 7 ≤ 1x − 52
−5x ≤ −45
x ≤ 9
What mistake did Andrew make in solving the inequality? (2 points)
He subtracted 1x from both sides when he should have added 4x.
When dividing by −5, he did not change the ≤ to ≥.
He added 7 to both sides when he should have added 52.
He did not make a mistake.
Try this option:
rule: if to make a dividing by negative number (<0), the inequatlity sign must be changed to opposite.
According the rule described above, the correct answer is
'When dividing by -5, he did not change the ≤ to ≥'.
When dividing by - 5 he did not change ≤ to ≥
His calculations are correct down to the line - 5x ≤ 9
When dividing or multiplying by a negative quantity the inequality symbol must be reversed, thus
- 5x ≤ 9 ( divide both sides by - 5 )
x ≥ 9 ← inequality symbol reversed

Megan is going on a long distance road trip. She drives for 13 miles before being able to travel at a constant speed using cruise control. The equation used to find her total distance traveled is shown below.
y = 59x + 13
If y is the total number of miles driven, and x is the number of hours driven after reaching 13 miles, which statement best describes the rate of change in the distance traveled?
A. For every 13 hours, she will drive 72 miles.
B. For every two hours, she will drive 59 miles.
C. For every hour, she will drive 59 miles.
D. For every hour, she will drive 72 miles.
The rate of change of y (miles traveled) with respect to x (time in hours) is 59, the coefficient of x. The appropriate choice is ...
... C. For every hour, she will drive 59 miles.
The equation y = 59x + 13 shows that Megan's rate of change in distance traveled is 59 miles for every hour driven at cruise control, after the first 13 miles. So, the correct answer is C. For every hour, she will drive 59 miles.
The equation y = 59x + 13 represents Megan's total distance traveled after driving the first 13 miles without cruise control. The variable y stands for the total number of miles driven, and x represents the number of hours driven at a constant speed using cruise control. To identify the rate of change in the distance traveled, we look at the coefficient of x in the equation, which is 59. This coefficient indicates how many miles are added to the initial 13 miles for every hour of driving at cruise control. Therefore, for every hour, Megan will drive 59 miles after the initial 13 miles are accounted for. It is important to note that the initial 13 miles are a fixed distance and do not change with time. Thus, the correct statement describing the rate of change in the distance traveled is C. For every hour, she will drive 59 miles after the first 13 miles.

Step-by-step explanation:
Jimmy ran with the speed of m miles per hour. How far did he run in t minutes?
Answer:
Jimmy run in t minute = [tex]\frac{m*t}{60}[/tex] miles.
Step-by-step explanation:
Given : Jimmy ran with the speed of m miles per hour.
To find : How far did he run in t minutes.
Solution : We have given
Speed = m miles per hour .
Speed = [tex]\frac{Distance}{time}[/tex].
We can say in 1 hour Jimmy ran =m miles.
1 hour = 60 minute .
Jimmy ran in 60 minute = m miles .
Jimmy run in 1 minute = [tex]\frac{m}{60}[/tex] miles.
Jimmy run in t minute = [tex]\frac{m}{60}* t[/tex] miles.
Jimmy run in t minute = [tex]\frac{m*t}{60}[/tex] miles.
Therefore, Jimmy run in t minute = [tex]\frac{m*t}{60}[/tex] miles.
The distance covered by Jimmy after t minutes is
[tex]m \: \times ( \frac{t}{60} )[/tex]
Recall :
Distance = Speed × Time
Speed = m miles per hour
Time = t minutes
Converting t to hours :
Recall :
1 hour = 60 minutes
t minutes = t/60 hours
Multiplying Jimmy's speed by the number of minutes run
Distance covered :
[tex]m \: \times ( \frac{t}{60} )[/tex]
