Teah was selling candy bars for a fundraiser. She spent $25 on a box of candy bars and sold each candy bar for $2.50. Her profit was $75. Teah wrote the equation 2.5c−25=75 for this situation, and she found c=40.
Which statement is true about the solution c=40?
The solution c=40 is the selling cost of each candy bar, in dollars.
The solution c=40 is the selling cost of a box of candy bars, in dollars.
The solution c=40 is the number of candy bars Teah sold.
The solution c=40 is the amount in dollars that Teah spent on a box.
The solution c=40 is the profit in dollars Teah made from each candy bar.
Answer: The solution would be C
Step-by-step explanation:
If we multiply 40 candy bars by $2.50 we would get the answer of $100 because that is how much she made from selling candy bars. . Then we would have to subtract that answer by $25 because that is how much the box cost. $100 minus $25 is equal to $75. So the answer would be option C

What is the point-slope form of a line with slope 6 that contains the point
(1,2)?
A. y + 2 = 6(x - 1)
B. y+ 2 = 6(x+1)
C. y-2 = 6(x-1)
O D. x+ 1 = 6(y+2)
Answer:
The answer is option CStep-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (1,2) and the slope is 6
The equation of the line in point slope form is
[tex]y - 2 = 6( x - 1)[/tex]Hope this helps you

¿Cuál es la razón en la que está segmentada la línea que une a los puntos A(-2,3) y B(4,-1) si se sabe que el Pr es (0,5/3)?
Answer:
Entonces la proporción es 1/2
Step-by-step explanation:
Aquí, en esta pregunta, queremos encontrar la razón que divide al segmento AB en la razón (0,5 / 3).
Usamos la fórmula de división interna para esto;
Sea la relación m / n Matemáticamente, la fórmula de división que da lugar a (0,5 / 3) es la siguiente;
(x, y) = mx2 + nx1 / (m + n), my2 + ny1 / (m + n)
En este caso particular;
(x1, y1) = (-2,3)
(x2, y2) = (4, -1)
(x, y) = (0,5 / 3).
Así que hagamos las sustituciones; (0,5 / 3) = m (4) + n (-2) / (m + n), m (-1) + n (3) / (m + n)
(0,5 / 3) = (4m -2n) / (m + n), (-m + 3n) / m + n.
Por tanto, equiparemos términos;
4m-2n / (m + n) = 0
4m -2n = 0
4m = 2n
n = 4 m / 2
n = 2 millones •••••••• (i)
(3n -m) / (m + n) = 5/3
3 (3n -m) = 5 (m + n)
9n - 3m = 5m + 5n
9n -5n = 3m + 5m
4n = 8m
n = 8 m / 4 n = 2m ••••••• (ii)
Podemos ver que ambos son iguales;
n = 2 m 1 = 2m / n
divide ambos lados por 2
m / n = 1/2.
What number could replace x to make a true statement?
2/3 < x/8 < 7/8
Answer:
x=6
Step-by-step explanation:
1. get the gcf of 3 and 8
3×8=24
2.the new equation would be this:
16/24<3x/24<21/24
3. the value of x would be 6 because 3×6=18.
3×5=15 wouldnt make sense because it is is smaller than 16.
The sphere shown below is placed in a full overflow cup and sinks to the bottom. How much water is displaced by the sphere?Lector inmersivo
(1 Punto)
A. 51.0 mL
Option 2
C. 88.6 mL
D. 407.7 mL
B. 66.5 mL
Answer:
A. 51.0 mLStep-by-step explanation:
Given
The sphere with the diameter of 4.6It displaces the amount of water equal to its volume
Volume of the sphere:
V = 4/3πr³V = 4/3π(d/2)³ = 1/6πd³V = 1/6*3.14*4.6³ = 50.939 ≈ 51.0 cm³ = 51.0 mlCorrect option is A. 51.0 mL
Answer:
A
Step-by-step explanation:
We are given a diameter of 4.6
4.6 / 2 = 2.3 (radius)
Volume of a sphere [ V = 4/3πr² ]
V = 4/3π(2.3)²
V = 4/3π(5.29)
V = 4/3(38.20438)
V ≈ 51

These are corresponding angles since they both connect a parallel line and the transversal. This means they are congruent and have the same value. So, we can set up the following equation.
8x-8=5x+25
Subtract 5x from both sides.
3x-8=25
Add 8 to both sides.
3x=33
Divide both sides by 3.
x=11.

Answer:

∠B = 80
Step-by-step explanation:
∠A = ∠B
where
∠A = 8x - 8°
∠B = 5x + 25°
8x - 8° = 5x + 25°
8x - 5x = 25 + 8
3x = 33
x = 33/3
x = 11
plugin x into ∠B = 5x + 25°
∠B = 5x + 25°
∠B = 5(11) + 25°
∠B = 80

2. Give recursive definitions for the following sets. a. The set of all strings over {a, b} containing at least one "a". b. The set of odd-length binary strings that end with 00.
Answer and explanation:
Recursive is related to repeat the definition, rule, and procedure.
a) The set of all strings over {a,b} containing at least one a.
Let x is a string containing at least one a: x=a and y= b
Sets of union of XY and yx will be (XY) (yx) = (a,b) (b, a)
b) The set of odd length binary strings that end with 00
There is a regular expression compared with two 00, which is surrounded by 0+1 with at least two 0s.

Answer: Lin is the most consistent and I would want to have them on my team.
Why is this? Because their dots are more clustered together compared to the other distributions. Elena may have made the most shots (9) at one point, but her data set is very spread out and more unpredictable. The more spread out a data set is, the higher the variance and standard deviation. The range is also affected by how spread out the data set is since
range = max - min
So in a rough sense, the range can be used to estimate the variance and standard deviation. Though more accurate formulas are usually the better way to go.

Answer:
The coordinates of point B are : (-1, 1)
Step-by-step explanation:
[tex]\frac{-7+x^{2} }{2} = -4\\\frac{1+y^{2} }{2} =1[/tex] You multiply -4 by 2 which gives you -8 then you multiply 1 by 2 which gives 2.
Then you create the equations [tex]-7 + x^{2} = -8\\1 + y^{2} = 2[/tex] you substitute -7 for +7 and add 7 to -8 which gives -1 ([tex]x^{2}[/tex]) and subtract 1 from 2 which gives you 1 ([tex]y^{2}[/tex])
To check your answer use the midpoint formula [tex]\frac{-7+-1}{2} =\frac{-8}{2} =-4\\\frac{1+1}{2} =\frac{2}{2} =1[/tex] which gives you your midpoint (-4,1)

When we roll one die, we have a 1 in 6 probability of getting any particular number on the die. When we roll a pair of dice, there are 36 different pairs that can be produced, yet only 11 actual distinct values. Explain how the probability associated with the roll of each individual die in the pair explains the higher variability in the total outcome of the roll of each pair. How do the concepts of permutations and combinations apply to this example
Answer:
The probability of an event occurring depends on the sample space and the frequency of the event
permutations and combination principles would have to be applied to determine the probability of a particular number showing up when a pair of dice is rolled ,while a single dice roll have a fixed frequency of every event ( 1,2,3,4,5,6,) hence probability of a number showing up is 1/6
Step-by-step explanation:
The probability of an event occurring depends on the sample space and the frequency of the event
The total outcomes of rolling a pair of fair dice would be = ( total outcome of single dice A * total outcome of single Dice B ) = 6 * 6 = 36. and this is because the Two dice are independent of each other. hence there is a higher variability in the determining the possibility of a particular number ( 1,2,3,4,5,6) showing up when a pair of dice is rolled due to the larger sample space. permutations and combination principles would have to be applied to determine the probability of a particular number showing up when a pair of dice is rolled ,while a single dice roll have a fixed frequency of every event ( 1,2,3,4,5,6,) hence probability of a number showing up is 1/6
