The lines shown below are perpendicular. If the green line has a slope of
2/5 , what is the slope of the red line?
Answer:
-5/2
Step-by-step explanation:
for perpendicularity;
[tex]m1 = \frac{ - 1}{m2} [/tex]
where m1 is first slope
and m2 is second slope
so here, let m1 be green line slope
and m2 be red line slope
thus,
[tex]m2 = \frac{ - 1}{m1} [/tex]
[tex]m2 = \frac{ - 1}{ \frac{2}{5} } = - 1 \div \frac{2}{5} [/tex]
[tex] = - 1 \times \frac{5}{2} = \frac{ - 5}{2} [/tex]

A group of students are going on a trip and the trip costs $36.50 per student which includes $9.50 for lunch, an entrance ticket and a gift coupon. The gift coupon costs $50 for the entrance ticket. The cost of an entrance ticket is
A) $27.00
B) $25.00
C) $18.00
D) $13.50
Answer:
The answer is D) $13.50
Step-by-step explanation:
So first what you're gonna do it subtract $9.50 from $36.50 which will get you to $27.00.
Then you'll have to figure out what half of $27.00 is.
That will get you to the answer of D) $13.50

Forty students went on a trip on Wednesday. On Thursday, 15% less students went on a similar trip. How many students went on the trip on Thursday?
Answer:
34
Step-by-step explanation:
40 * .15= 6
40-6 = 34
okkk so you do 40 * .15 because you just put a decimal point before all percentages to convert it into number
40*.15= 6
then subtract 6 to the original amount
40-6=34
34 students went on the trip on thursday cause 6 students got killed by bears in the last trip.

Answer:
1. 65°
2. 115°
Step-by-step explanation:
1 is a linear pair
2 u just do 180 - 65 =___
that is ur answer
Answer:1. 65 2. 115
Step-by-step explanation:
the opposite side is 65 so is the one directly across it because it’s linear
A straight line is 180 so you subtract 65 from 180 to get 115

The equation that passes through (3,6) and is perpendicular to 3x - 4y = - 2
a
y = - 4/3x + 3 1/3
b
y = - 3/4x + 10
c
y = - 4/3x + 10
d
y = 3/4x + 10
Answer:
C
Step-by-step explanation:
We want the equation of the line that passes through (3, 6) and is perpendicular to:
[tex]3x-4y=-2[/tex]
First, convert the second equation into slope-intercept form:
[tex]-4y=-3x-2\Rightarrow \displaystyle y=\frac{3}{4}x+\frac{1}{2}[/tex]
So, we can see that the slope of the line is 3/4.
The slopes of perpendicular lines are negative reciprocals of each other.
Therefore, the slope of the new line is -4/3.
It passes through the point (3, 6).
We can use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Substitute:
[tex]\displaystyle y-(6)=-\frac{4}{3}(x-3)[/tex]
Distribute:
[tex]\displaystyle y-6=-\frac{4}{3}x+4[/tex]
Therefore:
[tex]\displaystyle y=-\frac{4}{3}x+10[/tex]
The answer is C.
Lucas has a 39-foot-long rope. He uses all the rope to outline this T-shape in his backyard. All the angles in the figure are right angles. (Work out and answer number 13 and number 14, please.)
Answer:
Step-by-step explanation:
The area of a shape is the amount of space it can occupy, while the perimeter is the sum of its sides.
The value of x is 7.5 ftThe area of the shape is 57 square feetGiven that:
[tex]P = 39[/tex] --- the perimeter of the shape
The value of x
The perimeter is the sum of all sides.
So, we have:
[tex]P = x + x + 3.5 + 3.5 + 3 + 3 + 9 + (9 - 3.5 - 3.5)[/tex]
Substitute 39 for P
[tex]x + x + 3.5 + 3.5 + 3 + 3 + 9 + (9 - 3.5 - 3.5) = 39[/tex]
[tex]2x + 24 = 39[/tex]
Collect like terms
[tex]2x = -24 + 39[/tex]
[tex]2x = 15[/tex]
Divide through by 2
[tex]x = 7.5[/tex]
The area of the shape
The shape can be divided into two rectangles
A 9ft by 3ft rectangleA (9 - 3.5 - 3.5)ft by x ft rectangleSo, the area of the shape is:
[tex]Area = 9ft \times 3ft + (9 - 3.5 - 3.5)ft \times x ft[/tex]
[tex]Area = 27ft^2 + 2ft \times x ft[/tex]
Substitute [tex]x = 7.5[/tex]
[tex]Area = 27ft^2 + 2ft \times 15 ft[/tex]
[tex]Area = 27ft^2 + 30 ft^2[/tex]
[tex]Area = 57 ft^2[/tex]
Hence, the area of the shape is 57 square feet.

Solve the following equations:
x/3+1=7/5
Answer:
8/5..............…is the answer
Answer:
Standard Form: 6/5 Mixed Number: 1 1/5 Decimal: 1.2
Step-by-step explanation:
1. Subtract 1 from both sides of the equation
x/3 + 1 = 7/5
x/3 + 1 - 1 = 7/5 - 1
2. Simplify
2a.
x/3 + 1 - 1 = 7/5 - 1
x/3 = 7/5 - 1
2b.
x/3 = 7/5 - 1
x/3 = 2/5
3. Multiply all terms by the same value to eliminate fraction denominators
x/3 = 2/5
3 x x/3 = 3 x 2/5
4. Simplify
4a. Cancel multiplied terms that are in the denominator
cross out the threes in 3 x x/3 then you should get x = 3 x 2/5
4b. Multiply the numbers
x = 3 x 2/5
x = 6/5
And your answer should be 6/5|

The combined height of one fir tree and one pine tree is 21 meters. The height of 4 fir trees stacked on top of each other is 24 meters taller than one pine tree.
How tall are the types of trees that Logan genetically engineered?
Answer:
The pine is 12 m tall and the fir is 12 m tall
Step-by-step explanation:
System of Equations
Let's call:
x = height of a pine tree
y = height of a fir tree
The combined height of one fir tree and one pine tree is 21 meters. This leads to the equation:
x + y = 21 [1]
The height of 4 fir trees is 24 meters taller than one pine tree:
4y = x + 24 [2]
From [1]:
x = 21 - y [3]
Substituting in [2]:
4y = 21 - y + 24
Adding y:
5y = 45
Dividing by 5:
y = 9
Substituting in [3]:
x = 21 - 9 = 12
The pine is 12 m tall and the fir is 12 m tall

Answer:
Problem 1: y = 4x + 6
Problem 2: 48 soda bottles per minute
Step-by-step explanation:
Problem 1:
Equation of a line in slope-intercept form is given as y = mx + b.
Wee have to figure out the value of the slope (m) and the value of y-intercept (b). Them to write an equation that represents the line of the graph, we need to input the values of m and b into the equation, y = mx + b.
Thus,
m = hourly fee = $4
b = initial deposit = $6
Substitute m = 4 and b = 6 into y = mx + b
Equation would be:
y = 4x + 6
Problem 2:
What we are simply asked to do is to find the slope of the line, which is the number of soda bottles the machine will produce per minute
Using the two points (3, 144) and (8, 384),
Slope = ∆y/∆x = (384 - 144)/(8 - 3)
Slope = 240/5 = 48
Thus, the machine will make 48 bottles per minute
