Answer:

122 Minutes

Step-by-step explanation:

Start with $16.42

subtract $3 for the monthly fee, 16.42-3= $13.42

he pays $0.11 per minute so that's 13.42 x (1min/0.11) = 122minutes

On Tuesday, Marissa was $45 short of her fundraising goal. The next day, she was $5 over her goal write an equation to show how

scoray [572]

Answer: Hello daema, let's let x be the goal and c be the collection per day.

x - 45 + c = x + 5 is the answer so now let's talk about how we did that.

So she wants to get to x which is the goal. But right now she has 45 less than what her goal is. So that would look like this x - 45 now she has to get c or the collection per day to get to her goal. So now it looks like this x - 45 + c. Now that c has to be at least x which is her goal, it now will look like this x - 45 + c = x. But we're not done, the question said that now she 5$ over her goal, or x. So we have to add the + 5 onto the end so now it looks like this x - 45 + c = x + 5. To solve the equation "if you have to" it would be x = 50$ per day.

Solve for v 17 - 2v = -53solve for v 17-2v=-53

lapo4ka [179]

Hey!

------------------------------------------------

Steps To Solve:

17 - 2v = -53

~Subtract 17 to both sides

17 - 2v - 17 = -53 - 17

~Simplify

-2v = -70

~Divide 2 to both sides

-2v/-2 = -70/-2

~Simplify

v = 35

------------------------------------------------

Hence, the answer is $\Large\boxed{\mathsf{v~=~35}}$

Dawn needs to pour 3 gallons of water into her fish tank. She only has a 1 cup measuring cup. How many cups of water should she

Sunny_sXe [5.5K]

So you know 1 gallon equals 16 cups

So you multiply 16 times 3 equals 48

What is the equation of the circle with center (-3,1) that passes through the point (-5, 3)?

Natali5045456 [20]

Answer:

Option B) (x + 3)^2 + (y – 1)^2 = 8 is the correct answer.

Step-by-step explanation:

The equation of a circle with center (h,k) and radius r is given by:

$(x-h)^2 + (y-k)^2 = r^2$

Given

Center = (h,k) = (-3,1)

=> h = -3

=> k = 1

The distance between the center of circle and the point through which the circle passes will be the radius.

The distance formula is given by:

$r = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

Given

$(x_1,y_1) = (-3,1)\\(x_2,y_2) = (-5,3)$

Putting the values in the formula

$r = \sqrt{(-5+3)^2+(3-1)^2}\\r = \sqrt{(-2)^2+(2)^2}\\r = \sqrt{4+4}\\r = \sqrt{8}$

Putting the values of h,k and r in general form of equation

$\{x-(-3)}^2\} +(y-1)^2 = (\sqrt{8})^2\\(x+3)^2+(y-1)^2 = 8$

Hence,

Option B) (x + 3)^2 + (y – 1)^2 = 8 is the correct answer.

Someone please help me with this

Nadusha1986 [10]

Since 2 sides of the triangle are the same, it's an isosceles triangle.
That would also mean that the two angles are the same; 70 and 70.

A triangle has 180 degrees total.

70 + 70 + x = 180
x = 40
