Answer:
There would be 20 jars of creamy peanut butter.
Step-by-step explanation:
You have 100 jars of peanut butter divide that by 100. That would give you the amount for 1%. Multiply that by 20 for the 20% which will give you your answer of 20.
100/100=1
1*20=20
Number of creamy peanut butter jars is 20.
Final answer:
The factory made 20 jars of creamy peanut butter, which is calculated by finding 20% of the total 100 jars produced.
Explanation:
The student has asked how many jars of creamy peanut butter were made if a factory produced 100 jars and 20% of them contained creamy peanut butter. To find the answer, we simply need to calculate 20% of 100 jars.
Here is the calculation:
First, we convert the percentage to a decimal: 20% = 0.20.
Next, we multiply the total number of jars by this decimal: 100 jars × 0.20 = 20 jars.
Therefore, the factory made 20 jars of creamy peanut butter.

Find a pair of numbers that is a member of both y=-3x-27 and y=5+x
Answer:
(x, y) = (-8, -3)
Step-by-step explanation:
If all you want is a quick solution, I find a graphing calculator to be very handy. The one used in the attachment shows the solution to be (x, y) = (-8, -3).
_____
You can use one equation to substitute for y in the other equation:
-3x -27 = 5 +x
-32 = 4x . . . . . . add 3x-5 to both sides
-8 = x . . . . . . . . divide by 4
y = 5 +(-8) = -3 . . . . . use the second equation to find y
The pair of numbers that satisfies both equations is ...

================================================
Explanation:
If points F and E are the midpoints of segment VU and segment ST respectively, then segment FE is the midsegment of the trapezoid. The midsegment is parallel to the bases, and the midsegment's length is found by adding up the bases VS and UT, then dividing by 2.
(VS + UT)/2 = FE

What is 8x to the second power plus 10x
The expression [tex]8x^2 + 10x[/tex] factors to [tex]2x(4x + 5)[/tex] and has solutions x = 0 and x = -5/4.
We first need to understand what it represents. In this expression, [tex]x[/tex] is the variable, and the terms [tex]8x^2[/tex] and [tex]10x[/tex] are polynomial terms where:
[tex]8x^2[/tex] indicates that the variable [tex]x[/tex] is raised to the power of 2, meaning it is multiplied by itself ([tex]x \times x[/tex]) and then scaled by a factor of 8.
[tex]10x[/tex] means that the variable [tex]x[/tex] is multiplied by 10.
The first term is [tex]8x^2[/tex].
The second term is [tex]10x[/tex].
In this case, the terms are not like terms because one is [tex]x^2[/tex] and the other is [tex]x[/tex]. Therefore, they cannot be combined further. The expression is simplest as it stands, which is: [tex]8x^2 + 10x[/tex]
Factoring out [tex]2x[/tex] gives us:
[tex]2x(4x + 5)[/tex]
Thus, [tex]8x^2 + 10x[/tex] can also be expressed as [tex]2x(4x + 5)[/tex]. This is useful if you are trying to find the roots of the equation (setting it equal to zero) since it can help identify the values of [tex]x[/tex] that satisfy the equation [tex]8x^2 + 10x = 0[/tex].
This gives two possible solutions for x:
2 * x = 0 which leads to x = 0
4 * x + 5 = 0 which leads to x = -5/4

What are all possible functions from 1 to 9
Answer:
In mathematics, a function (f) is a relationship between a given set X (called domain) and another set of elements Y (called codomain) so that each element x of the domain corresponds to a single element f (x) of the domain (the that form the route, also called scope ranking).
See: Relations and functions
In everyday or simpler language, we will say that mathematical functions are equivalent to the common logical process that is expressed as "dependent on."
Mathematical functions can refer to everyday situations, such as: the cost of a phone call that depends on its duration, or the cost of sending a parcel that depends on its weight.
As an example, what would be the rule that relates the numbers on the right with those on the left in the following list ?:
1 --------> 1
2 --------> 4
3 --------> 9
4 --------> 16
The numbers on the right are the squares of those on the left.
The rule is then to "square":
1 --------> 1
2 --------> 4
3 --------> 9
4 --------> 16
x --------> x 2.
To refer to this rule we can use a name, which is usually the letter f (of function). So, f is the rule "square the number".
Usually two notations are used:
x --------> x 2 or f (x) = x 2.
Thus, f (3) means applying the rule f to 3. Doing so results in 3 2 = 9.
Then f (3) = 9. Similarly f (2) = 4, f (4) = 16, f (a) = a 2, etc.
Which value of n makes the equation true? 6n − 2(4n + 7) + 4 = -2
Answer:
n = - 4
Step-by-step explanation:
Given
6n - 2(4n + 7) + 4 = - 2 ← distribute and simplify left side
6n - 8n - 14 + 4 = - 2
- 2n - 10 = - 2 ( add 10 to both sides )
- 2n = 8 ( divide both sides by - 2 )
n = - 4
To solve the equation 6n - 2(4n + 7) + 4 = -2, we apply the distributive property and combine like terms to simplify. The solution is n = -4.
To solve the equation 6n - 2(4n + 7) + 4 = -2, we need to apply the distributive property and combine like terms to simplify.
Distribute the -2 to both terms inside the parentheses: -2(4n + 7) = -8n - 14.Combine like terms: 6n - 8n - 14 + 4 = -2.Combine like terms again: -2n - 10 = -2.Next, we isolate the variable n by adding 10 to both sides: -2n - 10 + 10 = -2 + 10.Simplify: -2n = 8.Finally, solve for n by dividing both sides by -2: n = 8 / -2.Therefore, the value of n that makes the equation true is n = -4.

Can you please help me with the problem in the image below?
Given data:
m∠P = m∠R and TP = SR
To prove that ΔQTP ≅ ΔQSR:
Consider ΔQTP and ΔQSR,
m∠P = m∠R (given angle)
TP = SR (given side)
m∠Q = m∠Q (common angle)
∴ ΔQTP ≅ ΔQSR (by ASA congruence rule)
Hence ΔQTP and ΔQSR are congruence triangles by Angle - Side - Angle congruence rule.

x = –5 or x = 3
Solution:
Given expression:
[tex]|-1-x|=4[/tex]
[tex]\Rightarrow |-x-1|=4[/tex]
⇒ –x – 1 = 4 or –x – 1 = 4
First take –x – 1 = 4.
Add 1 on both side of the equation.
⇒ –x – 1 + 1 = 4 + 1
⇒ –x = 5
Divide by –1 on both side of the equation, we get
⇒ x = –5
Now take –x – 1 = –4.
Add 1 on both side of the equation.
⇒ –x – 1 + 1 = –4 + 1
⇒ –x = –3
Divide by –1 on both side of the equation, we get
⇒ x = 3
x = –5 or x = 3
Hence the two values of x are –5 or 3.
20 business cards are placed in a hat, 10 belong to women, 10 belong yo men If 2 cards are drawn at once. what's the probability that the first is a Man's card and the Second, A woman's card?
5/19
14/19
1/4
9/10
Answer:
First choice:
[tex]\large\boxed{\large\boxed{5/19}}[/tex]
Explanation:
The probability that the first is a man's card and the second, a woman's card is calculated as the product of both probabilities, taking into account the fact that the second time the number of cards in the hat has changed.
In spite of it is said that the cards are drawn at once, since it is stated a specific order for the cards (first is a man's card and the second, a woman's card) you can model the procedure as if the cards were drawn consecutively, instead of at once.
1. Probability that the first is a man's card
Number of cards in the hat = 20 (the 20 business card)Number of man's card in the hat: 10Probability = favorable oucomes / possible outcomes = 10/20 = 1/2.2. Probability that the second is a woman's card
Number of cards in the hat = 19 (there is one less card in the hat)Number of wonan's card in the hat: 10Probability = favorable oucomes / possible outcomes = 10/19.3. Probability that the first is a man's card and the second, a woman's card
(1/2) × (10/19) = 5/19That is the first choice.

Answer:
79°
Step-by-step explanation:
Label the intersection of AE and CD point F. Then angle CFE is an alternate interior angle with angle BAE, so is congruent. The angle of interest is an exterior angle to triangle CFE, so is the sum of remote interior angles CFE (54°) and DCE (25°). That sum is ...
m∠AEC = 54° +25° = 79°
Based on the definition of alternate interior angles, the measure of ∠AEC is: 79°
What are Alternate Interior Angles?Interior angles that are alternating each other on a transversal are congruent, and are called alternate interior angles.
Thus:
m∠AEC = m∠BAE + m∠FCE
Substitute
m∠AEC = 54° + 25°
m∠AEC = 79°
Therefore, based on the definition of alternate interior angles, the measure of ∠AEC is: 79°

The graph at the right shows the relationship between distance and time for a car driven at a constant speed.
1. What is the speed?
2. Is this a function relationship?
3. If this is a function, write a rule to represent it.
Answer:
1. 60 miles per hour
2. Yes, linear
3. Y=60x
Step-by-step explanation:
1. Speed is 60 miles per hour.
2. A function relationship is a relationship between two variables.
3. The rule to represent the function is Distance = 60t.
1. What is the speed?
The speed of the car is the rate at which it is traveling. It is calculated by dividing the distance traveled by the time taken to travel that distance.
Speed = Distance / Time
From the graph, we can see that the car travels 120 miles in 2 hours. Therefore, the speed of the car is:
Speed = 120 miles / 2 hours = 60 miles per hour
2. Is this a function relationship?
A function relationship is a relationship between two variables where each input value has only one output value. In other words, for every value of the independent variable (in this case, time), there is only one corresponding value of the dependent variable (in this case, distance).
We can see from the graph that the distance traveled by the car increases linearly with time. This means that there is a one-to-one relationship between the two variables, and therefore the relationship is a function.
3. If this is a function, write a rule to represent it.
A rule for a function is a mathematical expression that shows how the dependent variable is related to the independent variable. In this case, the rule for the function would be:
Distance = Speed * Time
Substituting the speed of the car into the rule, we get:
Distance = 60 miles per hour * Time
Therefore, the rule to represent the function is:
Distance = 60t
where t is the time in hours.
