Answer:
Mary's class.
Step-by-step explanation:
One way to do this is to figure out how many students are in Alex's class and how many students are in Mary's class.
60% of Alex's class is 12 students
[tex]\frac{12*100}{60}[/tex] = [tex]\frac{1200}{60}[/tex]= 20 students
[tex]\frac{2}{3}[/tex] or 66.66% (repeating) of Mary's class is 14 students
[tex]\frac{14*100}{66.66}[/tex] = [tex]\frac{1400}{66.66}[/tex] = 21 students
(^^66.66 repeating)
Mary's class has more students than Alex's class.

Answer:
$2400
$12,400
Step-by-step explanation:
Simple interest equation:
PV(1+it)
we have
10000(1+.06*4)
10000(1.24)
12400
Subtract the PV to get the interest earned
12400-10000= 2400
We just found that the total would be 12,400 and so part B is already solved
hich scenario best describes an object with a displacement of zero?
A train moves uphill as it travels in a straight path.
A person walks 2 miles north and 2 miles west.
A ball rolls from the top to the bottom of a hill.
A race car starts and ends at the same point on a track.
Answer: C. A Ball Rolls from top to the bottom of a Hill
Step-by-step explanation: In order for this to be a displacement of 0, we need a vector quantity, so we need to specify a magnitude and direction in order to fully characterize it. Unlike distance, which can only get larger on any path taken, displacement can be positive, negative, or zero. Displacement is zero when you start and end at the same spot.
HELP ASAP PLEASE! I need to write an equation of the line in slope-intercept form.
Step-by-step explanation:
step 1. slope intercept form: y = mx + b
step 2. m (slope) = (4 - 5)/(3 - 0) = -1/3.
step 3. Pick one of the points: (0, 5).
step 4. b is 5, the y intercept.

A developer bought 78 trees at a total cost of $4050. The shade trees cost $45 each and the evergreens cost $60 each. How many of each type of tree were bought?
Answer:
Step-by-step explanation:
for 5 feet is $60
2 feet is $150.
sorry if this doesn't help!
The number of tree shades and evergreens will be 42 and 36, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
An engineer purchased 78 trees at an all-out cost of $4050. The overhanging trees cost $45 each and the evergreens cost $60 each.
Let 'x' be the number of tree shades and 'y' be the number of evergreens. Then the equations are given as,
x + y = 78 ...1
45x + 60y = 4050 ...2
From equations 1 and 2, then we have
45(78 - y) + 60y = 4050
15y = 540
y = 36
Then the number of tree shades will be given as,
x + 36 = 78
x = 78 - 36
x = 42
The number of tree shades and evergreens will be 42 and 36, respectively.
More about the solution of the equation link is given below.

Answer:
6
Step-by-step explanation:
We need to simplify this equation:
6.9 - 5 + 4.1
The reason why there is a negative sign in between 6.9 and 5 is that + and - become negative.
There is a chart that can help you with this:

En un triángulo rectángulo A es un ángulo agudo y Sen A = 4/5 ¿Cuál será el valor de Tan A?
Answer:
[tex]\displaystyle \tan A=\frac{4}{3}[/tex]
Step-by-step explanation:
Funciones Trigonométricas
La identidad principal en trigonometría es:
[tex]sen^2A+cos^2A=1[/tex]
Si sabemos que A es un ángulo agudo (que mide menos de 90°), su seno y coseno son positivos.
Dado que Sen A = 4/5, calculamos el coseno:
[tex]cos^2A=1-sen^2A[/tex]
Sustituyendo:
[tex]\displaystyle cos^2A=1-\left(\frac{4}{5}\right)^2[/tex]
[tex]\displaystyle cos^2A=1-\frac{16}{25}[/tex]
[tex]\displaystyle cos^2A=\frac{25-16}{25}[/tex]
[tex]\displaystyle cos^2A=\frac{9}{25}[/tex]
Tomando raíz cuadrada:
[tex]\displaystyle cos\ A=\sqrt{\frac{9}{25}}=\frac{3}{5}[/tex]
La tangente se define como:
[tex]\displaystyle \tan A=\frac{sen\ A}{cos\ A}[/tex]
Substituyendo:
[tex]\displaystyle \tan A=\frac{\frac{4}{5}}{\frac{3}{5}}[/tex]
[tex]\displaystyle \tan A=\frac{4}{3}[/tex]

1. 25 - 3x = 40
2. } (x – 10) = -4
Step-by-step explanation:
For no 1
25 - 3x = 40
- 3x = 40 - 25
- 3x = 15
- x = 15 / 3
Therefore x = - 5
Now for no. 2
1/3 ( x - 10) = - 4
( x - 10 ) = - 12
x = - 12 + 10
Therefore x = - 2
