The bus is 33.5 feet long. The city train is 45.9 feet longer than the bus. How long
is the city train?
Answer:
88.4
Step-by-step explanation:
33.5 + 45.9 = 88.4
The length of the city train is 79.4 feet.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Length of the Bus = 33.5 feet.
Length of the City train:
= Length of the Bus + 45.9
= 33.5 + 45.9
= 79.4 feet.
Thus,
The city train is 79.4 feet.

Answer:
(3, 10 ) and (7, 30 )
Step-by-step explanation:
Given the 2 equations
5x - y = 5 → (1)
2y - x² = 11 → (2)
Rearrange (1) expressing y in terms of x
y = 5x - 5 → (3)
Substitute y = 5x - 5 into (2)
2(5x - 5) - x² = 11
10x - 10 - x² = 11 ← rearrange into standard form
x² - 10x + 21 = 0 ← in standard form
(x - 3)(x - 7) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 7 = 0 ⇒ x = 7
Substitute these values into (3) for corresponding values of y
x = 3 → y = 5(3) - 5 = 15 - 5 = 10 ⇒ (3, 10 )
x = 7 → y = 5(7) - 5 = 35 - 5 = 30 ⇒ (7, 30 )

Finding slopes of the lines to determine their relationship
1. J(1, 9), K(7, 4), L(8, 13), M(-2, 1)
Slope of JK
m = (4-9)/(7-1) = -5/6Slope of LM
m = (1-13)/(-2-8) = -12/-10 = 6/5These lines are perpendicular as slopes are negative reciprocal
2 J(13, -5), K(2, 6), L(-1, -5), M(-4, -2)
Slope of JK
m = (6-(-5))/(2-13) = 11/(-11) = -1Slope of LM
m = (-1-(-5))/(-4-(-1)) = 4/(-3) = -4/3Lines are neither parallel nor perpendicular
3. J(-10, -7), K(-4, 1), L(-3, 2), M(-6, -2)
Slope of JK

Answer:
7 square feet per student
Step-by-step explanation:
To find "A per B", divide the quantity of A by the quantity of B. It can help to keep the units with the numbers.
Here, you want area per student, so divide area by students:
area per student = (357 ft²)/(51 students) = 7 ft²/student
The relationship is 7 square feet per student.

Answer:
8
Step-by-step explanation:
By Pythagoras theorem,
(hypotenuse)² = (altitude)² + (base)²
(17)² = x² + (15)²
(17)² - (15)² = x²
289 - 225 = x²
x² = 64

After accelerating for 20 seconds, a DeLorean sports car has a wide range of speeds that it can achieve, depending on traction. The distribution of speed follows an approximately normal distribution with a mean of 80 mph and a standard deviation of 7 mph. What percentage of the trials will give the DeLorean a speed between 66 mph and 87 mph?
Answer:
81.859%
Step-by-step explanation:
We solve the question using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 80 mph
σ is the population standard deviation = 7 mph
For x = 66 mph
z = 66 - 80/7
z = -2
Probability value from Z-Table:
P(x = 66) = 0.02275
For x = 87 mph
z = 87 - 80/7
z = 1
Probabilith value from Z-Table:
P(x = 87) = 0.84134
The probability of the trials will give the DeLorean a speed between 66 mph and 87 mph is calculated as:
P(x = 87 mph) - P(x = 66 mph)
0.84134 - 0.02275
= 0.81859
The percentage of the trials will give the DeLorean a speed between 66 mph and 87 mph?
100 × 0.81859

What is the solution to this equation?
–0.2(x – 20) = 44 – x
Answer: x=50
Step-by-step explanation:
Use the distributive property to multiply -0.2 by x-20.
-0.2x+4=44-x
Add x to both sides.
-0.2x+4+x=44
Combine -0.2x and x to get 0.8x.
0.8x+4=44
Subtract 4 from both sides.
0.8x=44-4
Subtract 4 from 44 to get 40.
0.8x=40
Divide both sides by 0.8.
x=40/0.8
Expand 40/0.8 approx 50 by multiplying both numerator and the denominator by 10.
X=400/8
Divide 400 by 8 to get 50.
x=50

Answer:
(0, -5)
Step-by-step explanation:
The answer is in the equation you gave for the line. In the formula for the equation of a line, y = mx + b, b is the y-intercept, and since because the y-intercept is shown in a graph in the form of (0,b), the answer is (0, -5).
Which equation in slope-intercept form has a graph that passes through
the point (-3,6) and has a slope of 2 ?
