Step-by-step explanation:
The sum of degrees in a triangle is 180, so we have:
3x+100+x-4=180
add 4 on both sides
3x+100+x=184
subtract 100 on both sides
3x+x=84
Combine like terms
4x=84
84/4 = 21

pablo will rent a car for the weekend. he can choose one of two plans. the first plan has an initial fee of $55.96 with additional costs of $0.12 per mile driven. the second plane has an initial fee of $63.96 and costs an additional $0.08 per mile driven. how many miles does pablo drive to make the miles the same?
Answer:
200 miles
Step-by-step explanation:
First, set up the equations.
plan 1: initial fee of $55.96, $0.12 per mile
y = 0.12x + 55.96plan 2: initial fee of $63.96, $0.08 per mile
y = 0.08x + 63.96We want to know at what distance will the cost be the same. So, set the equations equal to each other.
0.12x + 55.96 = 0.08x + 63.96
Combine the variables.
0.04x + 55.96 = 63.96
Combine the constants.
0.04x = 8
Divide by 0.04 to isolate x.
x = 200 miles
Check by plugging x back into each equation.
y = 0.12(200) + 55.96
y = 24 + 55.96
y = $79.96
y = 0.08(200) + 63.96
y = 16 + 63.96
y = $79.96
You are correct!

Find the equation of the circle centered at $(1,-4)$ with radius 3.
Write your equation in the form "$(x - h)^2 + (y - k)^2 = r^2$".
Answer:
[tex](x-1)^2+(y+4)^2=9[/tex]
Step-by-step explanation:
The equation of a circle is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where (h, k) is the center and r is the radius.
The center of the circle is (1, -4).
And the radius is 3.
Substitute:
[tex](x-(1))^2+(y-(-4))^2=(3)^2[/tex]
Simplify. Thus, our equation is:
[tex](x-1)^2+(y+4)^2=9[/tex]
Answer: (x-1)^2+(y+4)^2=9

Roberta bought 9/10 pound of raisins. She put 2/5 pound in bags for her lunch. How many 2/5 pound bags can Roberta fill? Does she have any left over?
Answer:
2 pound bags and have a remeinder of 1/10
Step-by-step explanation:
Answer:
She can fill 2 bags for her lunch and will have 1/10 pound left.
Step-by-step explanation:
It is easier if there is a common denominator, so I made the 2/5 into 4/10, so it is the same as 9/10 pound she bought.
4/10 is one bag, and if you double that, it is 8/10 pounds used. This is two bags of raisins for her lunch.
9/10 - 8/10 leaves 1/10 pound remaining, and not in a bag.
A squar has an area of 64cm2 find the perimeter of the square
Answer: 32 cm
Step-by-step explanation:
Answer:
All of the sides of the square are 8 cm. So the prementer would be 32 cms
Step-by-step explanation:
To find the sides of the square, you got to think what x what = 64. This shows you that 8 x 8 is 64. and since it is a square, all of the sides are the same. So 8+8+8+8 = 32 or you can do 8 x 4 = 32

A watermelon weighs 6.45 kilograms. How many grams does the watermelon weigh?
Answer:
A watermelon weighs about 3 (grams /(kilograms) 3.
Step-by-step explanation:
Answer:
6,450 g
Step-by-step explanation:
Since there are 1000 grams in 1 kilogram, you multiply 6.45 kg x 1000 g.
6.45 x 1000 g equals 6,450 grams. Move the decimal 3 times to the right because there are 3 zeroes in 1000.
You always move your decimal to the right when multiplying decimals.

Jack and Jill each go out shopping.
Jack spends 1/3 of his money.
Jill spends 40% of her money.
Frank says Jack spent more because 1 /3 is greater than 40%.
Alice says you cannot tell who spent more.
Who do you agree with, Frank or Alice? Explain why.
I agree with Alice because you do not know how much money Jill and Jack had before they went shopping. If they had the same amount of money Jill would have spent more because 40 percent is greater than 1/3.

Function c is defined by the equation c(n)=50+4n. It gives the monthly cost, in dollars, of visiting a gym as a function of the number of visits, n. What is the inverse function.
Answer:
(x - 50 / 4) = y
Step-by-step explanation:
On photo
To find the inverse function, you will have to write n in terms of c (which means number of visits as function of monthly cost).
The inverse function would be:
[tex]n = \dfrac{c-50}{4}[/tex]
Given that:c(n) = 50 + 4nc is monthly cost in dollars, of visiting a gym.n is the number of visits.To find:Inverse function of given function.
What is inverse function and when is it possible to find such function?The inverse function of f is a function of f which can remove the effect of f on its input.
Inverse is only possible if the function f is bijective (one to one correspondence, which means one input to one output uniquely and one output is connected to only one input by mapping f)
Since the given function is a linear function and not a vertical line, thus, one input n uniquely maps to one output cost and one cost uniquely is obtained by one and only one value of n.
Finding the inverse function of c(n) = 50 + 4n:[tex]cost = 50 + 4n\\ 4n = cost - 50\\\\ n = \dfrac{\text{c - 50}}{4} \text{\: (assuming cost to be denoted by c)}[/tex]
Thus, we have the inverse function of given function as:
[tex]n = \dfrac{c-50}{4}[/tex]

Which is an equation in point slope form for the given point and slope? Point: (-3,7) Slope: 4
Answer:
y-7=4x(x+3)
Step-by-step explanation:
(The 4x is 4 times ...)
Answer:
[tex]y -7 = 4(x+3)[/tex]
Step-by-step explanation:
Point-slope form is in the format of [tex]y-y_1 = m (x-x_1)[/tex]. When knowing a line's slope and a point it passes through, you can write an equation in that format. The [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] must be substituted for with real values.
The [tex]m[/tex] represents the slope, thus substitute 4 for [tex]m[/tex]. [tex]x_1[/tex] represents the x-value of one point the line passes through, while [tex]y_1[/tex] represents that same point's y-value. The line passes through (-3, 7), so substitute -3 for [tex]x_1[/tex] and 7 for [tex]y_1[/tex]. This gives the following answer and equation:
[tex]y-(7) = 4(x-(-3))\\y -7 = 4(x+3)[/tex]

Answer:
The correct answer is A, 14%.
Step-by-step explanation:
All you have to do is take the 30% chance of you HAVING to stop at the first light and find the chance that you won't have to stop at the first light, which is 70%, or .7. Then you take the chance of having to stop at the second light which is 80%, and find the probability of NOT having to stop there, which is 20%, or .2. Then you multiply the probabilities of not having to stop, which equals .14.
