Answer:
Cory bought 6.30 gallons of gas at the gas station.
Step-by-step explanation:
total amount = cost of snacks + amount spent on gas
[tex]$\$ 24.00=\$ 6.50+\$ 2.78 \mathrm{~g}$[/tex]
[tex]$\$ 2.78 \mathrm{~g}=\$ 24.00-\$ 6.50$[/tex]
[tex]$\$ 2.78 \mathrm{~g}=\$ 17.50$[/tex]

Find the missing probability. P(A)=2/5,P(B|A)=920,P(A∩B)
I think you meant P(B | A) = 9/20.
By definition of conditional probability,
P(B | A) = P(A ∩ B) / P(A)
so that
P(A ∩ B) = P(A) × P(B | A) = 2/5 × 9/20 = 18/100 = 9/50
Find the vertex and length of the latus rectum for the parabola. y=1/6(x-8)^2+6
Step-by-step explanation:
If the parabola has the form
[tex]y = a(x - h)^2 + k[/tex] (vertex form)
then its vertex is located at the point (h, k). Therefore, the vertex of the parabola
[tex]y = \dfrac{1}{6}(x - 8)^2 + 6[/tex]
is located at the point (8, 6).
To find the length of the parabola's latus rectum, we need to find its focal length f. Luckily, since our equation is in vertex form, we can easily find from the focus (or focal point) coordinate, which is
[tex]\text{focus} = (h, k +\frac{1}{4a})[/tex]
where [tex]\frac{1}{4a}[/tex] is called the focal length or distance of the focus from the vertex. So from our equation, we can see that the focal length f is
[tex]f = \dfrac{1}{4(\frac{1}{6})} = \dfrac{3}{2}[/tex]
By definition, the length of the latus rectum is four times the focal length so therefore, its value is
[tex]\text{latus rectum} = 4\left(\dfrac{3}{2}\right) = 6[/tex]
solve for y:
x^3 + (1/a)y= xy+9
Step-by-step explanation:
[tex] {x}^{3} + ( \frac{1}{a} )y = xy + 9[/tex]
[tex]x {}^{3} + \frac{y}{ay} = xy + 9[/tex]
[tex]x {}^{3 } = xy + 9 - \frac{y}{ay} [/tex]
[tex] {x}^{3} - 9 = xy - \frac{y}{ay} [/tex]
[tex] {x}^{3} - 9 = y(x - \frac{1}{a} )[/tex]
Divide both sides by x-1/a
[tex] \frac{x {}^{3} - 9}{x - \frac{1}{a} } = y[/tex]

Find x+y
Answer:
62
Step-by-step explanation:
2y-5 and 95 are vertical angles so they are equal
[tex]2y - 5 = 95[/tex]
[tex]2y = 100[/tex]
[tex]y = 50[/tex]
3x and 144 form a linear pair angle so
[tex]3x + 144 = 180[/tex]
[tex]3x = 36[/tex]
[tex]x = 12[/tex]
x=12 and y=50 so
[tex]12 + 50 = 62[/tex]
Answer:
x + y = 62
Step-by-step explanation:
To find x + y we first need to find the value of x and y separately
first to find x
3x + 144 = 180 (linear pair property used)
3x = 180 -144
3x = 36
x = 36/3
x = 12
Now we need to find the value of y
2y - 5 = 95 (vertically opposite angles are equal)
2y = 95 +5
2y = 100
y = 100/2
y = 50
Now they are asking to add
x + y = ?
12 + 50
= 62

197 people were in the survey. First we can subtract 57 from 197 because 57 people dont like cats or dogs.
197-57 = 140
and to find the number of people that chose cats but not dogs, we subtract 106 from 140 which leaves us with 34 people.

Which equation represents a line that passes through the points (5,-2) and (8,4)?
A. y= -2x*8
B. y= 1/2x-9/2
C. y=x-6
D. y=2x-12
Answer:
The correct choice is option D. y = 2x -12
Step-by-step explanation:
slope of the points (5,-2) and (8,4) is m = 2
y — intercept of the points (5,-2) and (8,4) is b = -12
Now, put it all together, and you'll get : y = 2x -12

thank you !
The 5/12 cups of dog food are recommended for a 25-pound adult dog
Step-by-step explanation:
Given:
The relationship between the weight of the adult dog (X) and the amount of dog food in cups (Y) is proportional.
To find:
Dog food for the 25-pound adult dog
Solution:
The weight of the adult dog (X) is proportional to the amount of dog food in cups are proportional.
[tex]X\propto Y\\\text{The equation for the relationship will be given as :}\\X=kY\\k=\frac{X}{Y}= Constant[/tex]
From the table given, we can calculate the value of the constant k.
[tex]k=\frac{10}{\frac{1}{6}}=\frac{40}{\frac{2}{3}}=\frac{50}{\frac{5}{6}}=\frac{100}{1\frac{2}{3}}\\k=\frac{10}{\frac{1}{6}}=\frac{40}{\frac{2}{3}}=\frac{50}{\frac{5}{6}}=\frac{100}{\frac{5}{3}}\\k=\frac{60}{1}=\frac{40\times 3}{2}=\frac{50\times 6}{50}=\frac{100\times 3}{5}\\k=60[/tex]
Let the dog food recommended for the 25-pound adult dog be y.
Weight of the dog = x = 25 pounds
Cups of dog food recommended = y
k = 60
Using the equation for the given relationship:
[tex]25=60\times y\\y=\frac{25}{60}=\frac{5}{12}[/tex]
The 5/12 cups of dog food are recommended for a 25-pound adult dog.
