Answer:
The slope of line g is [tex]\frac{2}{9}[/tex].
Step-by-step explanation:
We know that line f has a slope of [tex]-\frac{9}{2}[/tex] and that line g and line f are perpendicular to each other. Perpendicular lines have slopes that are opposite reciprocals of each other. Thus, the opposite reciprocal of [tex]-\frac{9}{2}[/tex] must be the slope of line g.
To find the opposite reciprocal of a number, change its sign and swap the numbers of the numerator and the denominator. So, the opposite reciprocal of [tex]-\frac{9}{2}[/tex] must be [tex]\frac{2}{9}[/tex]. [tex]\frac{2}{9}[/tex] has to be the slope of line g as well.

Answer:
System is given belowStep-by-step explanation:
Let (applicable to all three lines below)Hard candy = x kg with price $1.60/kgGummy worms = y kg with price $2.20/kgTotal weight = 50 kg with mixed price $1.75/kgRequired equations:
x + y = 50 total weight1.60x + 2.20y = 50*1.75 total price=========================================
Note. It says don't solve but the solution below for those who is interested to know the answer.
Simplify the second equation and solve by substitution x = 50 - y:
1.6(50 - y) + 2.2y = 87.580 - 1.6y +2.2y = 87.50.6y = 7.5y = 7.5/0.6y = 12.5Find the value of x:
x = 50 - 12.5 = 37.5Hard candy = 37.5 kg and gummy worms = 12.5 kg

Ya but how would you put that into an equation with letter c?
Put the following equation of a line into slope-intercept form, simplifying all fractions.
Answer:
y=1/2x-2
Step-by-step explanation:
2y=-4+x
2y=x-4 divide both sides by 2
y=1/2x-4/2
y=1/2x-2
Answer:
[tex]y = 0.5x - 2[/tex]
Step-by-step explanation:
Slope intercept form is
[tex]y = mx + b[/tex]
Our initial goal is to isolate y.
[tex]2y - x = -4[/tex]
Add x to both sides of the equation.
[tex](2y - x) + x = (-4) + x[/tex]
Simplify.
[tex]2y =x -4[/tex]
Divide both sides by 2.
[tex]\frac{2y }{2} = \frac{(x - 4)}2}[/tex]
Simplify.
[tex]y = 0.5x - 2[/tex]

Use the formula N = t2 − t/2, where N is the number of basketball games that must be scheduled in a league with t teams if each team is to play every other team once.
A league has 45 games scheduled. How many teams are in the league if each team plays every other team once?
teams
Answer:
t=7
Step-by-step explanation:
N=45
find t
45=t^2-t/2
0=t^2-t/2-45
use the quadratic formula
t=6.96~=7
Answer:
Step-by-step explanation:
45 = t2 - t/2
45 = 30(2) - 30/2
45 = 60 - 15
45=45
A cylinder shaped water tank has a diameter of 8 m and a height of 20 m.
What volume of water does the tank contain when it is 60% full?
Use 3.14 to approximate pi.
Enter your answer as a decimal to the hundredths place in the box.
___ m3
Answer:
602.88 cu ft.
Step-by-step explanation:
V = Bh where B is the area of the base, which is a circle in your problem.
Since the diameter is 8, the radius is 4.
So, B = [tex]\pi r^{2} = 3.14(4^{2} ) = 3.14(16) = 50.24[/tex]
V = Bh = 50.24(20) = 1004.8 cu ft = total volume of tank
60% of that volume is .60(1004.8) = 602.88 cu ft.

Answer:
bro fr doe gfnyjtuhgbfvjmhnbvc
Step-by-step explanation:
Can you help me, please?
Answer:
a. 18
b.144
c.108
Step-by-step explanation:
Using the given, Angle R equal 5x-54 and Angle T is 8u.
Also RS is congruent to ST. Since SR is congruent to ST, their opposite angles are also congruent using base angle theorem. So angle R is equal to Angle T. However, STU is a exterior angle so STU isn't congruent to SRT.
However, we can add , interior angle T, and STU to 180 to find x.
Interior angle T=SRT so interior angle t=5x-54.
Set up equation
[tex]5x - 54 + 8x = 180[/tex]
[tex]13x - 54 = 180[/tex]
[tex]13x = 234[/tex]
[tex]x = 18[/tex]
b.Plug 18 into 8x
[tex]8(18) = 144[/tex]
STU=144
c. Using the triangle exterior angle theorem, the exterior angle is equal to the measure of the sum of two non adjacent angles.
Angle S and Angle R are the non adjacent angle to STU.
So we cast up this equation.
[tex]5x - 54 + s = 180[/tex]
plug 18 in for x
[tex]5(18) - 54 + s = 144[/tex]
[tex]90 - 54 + s = 144[/tex]
[tex]36 + s = 144[/tex]
s=108
a truck has a trailer that has a length of 16 ft a width of 7 ft and a height of 11 ft what is the volume
Answer:
1232 is the volume because 16×7×11
Answer:
The volume is 1,232 ft³
Step-by-step explanation:
Volume = lwh = Length × Width × Height =
[given that the length is 16, width is 7, and height is 11]
16 × 7 × 11
4 × 4 × 7 × 11
2 × 2 × 2 × 2 × 7 × 11
2 × 2 × 2 × 2 × 77
2 × 2 × 2 × 154
2 × 2 × 308
2 × 616
1232
________
The volume is the measurable capacity of an object or the metrical space that something holds or takes up.
Just like you multiply the net length and width to find the area of a 2 dimensional object, you can extend that 2d object so that is has height by multiplying by the given height.
The washing machine had a selling price of P4,792. It had been marked up by P1,248. What was the cost? What was the mark-up rate?
Answer:
The cost of the washing machine is P 3,544
The mark-up rate is 35.21%
Step-by-step explanation:
1. We want to calculate the cost
Mathematically, this is the difference between the selling price and the mark up
We have this as;
4,792 - 1,248 = P 3,544
2. Here, we want to calculate the mark-up rate
Mathematically, this is the percentage of mark-up
That is;
mark-up/cost price * 100%
: 1,248/3,544 * 100% = 35.21%

Simplify the expression
8.8 (3.6d +1)
Answer:
31.68d + 8.8
Step-by-step explanation:
We have to simplify the expression but with one dillemma. The number 8.8 is outside the parenthesis of 3.6d + 1 and 3.6d + 1 aren't combinable because they aren't like terms.
When we have a problem like 8.8 being out of the parenthesis, we need to distribute 8.8 to both numbers in the parenthesis, or in other terms multiplying.
(8.8 * 3.6d + 1 * 8.8)
31.68d + 8.8
In the mail, you receive a coupon for $5 off for a pair of jeans, which is represented by the function j(x)=x−5. When you arrive at the store, you find that all jeans are 25% off, which is represented by the function s(x)=0.75x. Which of the functions below represents how much you would pay for a pair of jeans, C(x)=s(j(x)) , if you use the coupon first followed by applying the discount from the store? (Do not consider tax.)
A .C(x)=0.75x−5
B .C(x)=0.75(x−5)
C .C(x)=0.75x−x−5
D .C(x)=x−5−0.75
Answer: B
Step-by-step explanation: The function C(x) = s(j(x)) shows you how to solve it.
First in the parenthesis j(x) so you have to substitute since they told you
j(x) = x-5
Next s(x-5) and s(x-5) = 0.75(x-5) through substitution

Nikki drew a rectangle with a perimeter of 18 units on a coordinate grid. Two of the vertices were (4, –3) and (–1, –3). What could be the coordinates of the other two vertices of the rectangle?
Answer:
There are two possible solutions for the other two vertices of the rectangle:
(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)
Step-by-step explanation:
Geometrically speaking, the perimeter of a rectangle ([tex]p[/tex]) is:
[tex]p = 2\cdot b + 2\cdot h[/tex] (1)
Where:
[tex]b[/tex] - Base of the rectangle.
[tex]h[/tex] - Height of the rectangle.
Let suppose that the base of the rectangle is the line segment between (4, -3) and (-1, -3). The length of the base is calculated by Pythagorean Theorem:
[tex]b = \sqrt{[(-1)-4]^{2}+[(-3)-(-3)]^{2}}[/tex]
[tex]b = 5[/tex]
If we know that [tex]p = 18[/tex] and [tex]b = 5[/tex], then the height of the rectangle is:
[tex]2\cdot h = p-2\cdot b[/tex]
[tex]h = \frac{p-2\cdot b}{2}[/tex]
[tex]h = \frac{p}{2}-b[/tex]
[tex]h = 4[/tex]
There are two possible solutions for the other two vertices of the rectangle:
(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)
I'm having trouble solving the system of linear equations. This is the system: 5x + 6y = 50 x - 6y = -26 Can you please help me? Don't give the answer, but can you just explain?
Answer:
y = 5 ; x = 4
Step-by-step explanation:
Given :
5x + 6y = 50 - - - (1)
x - 6y = -26 - - - (2)
From (2)
x = - 26 + 6y
Put - 26 + 6y for x in (1)
5(-26 + 6y) + 6y = 50
-130 + 30y + 6y = 50
-130 + 36y = 50
-130 - 50 = - 36y
-180 = - 36y
y = 180 / 36
y = 5
Put y =5 in x = - 26 + 6y
x = - 26 + 6(5)
x = - 26 + 30
x = 4
y = 5 ; x = 4
