Answer: A. The mirror has a vertical orientation and is 5.4 ft tall.
Step-by-step explanation:
Since the y^2 value is being added first, and the value in its denominator is greater, we know that the ellipse has a vertical major axis.
Therefore, its orientation is vertical.
The square root of is 7.29, so 2.7 is the distance from the center to one of the ellipse's vertices. (You can research further into the equation for ellipses with vertical major axes to learn why that is.)
Multiply 2.7 * 2 = 5.4 to determine the full height of the mirror.
Yay! We figured out that "the mirror has a vertical orientation and is 5.4 ft tall".

At the football concessions stand, Tia sold 78 hamburgers and chicken tenders. If she
sold 24 more hamburgers than chicken tenders, how many hamburgers did she sell?
Answers
I am going to do this problem with more of an algebraic approach weather or not its the way your teacher wants you to do it like this.
The way to do things algebraically is to just set variables for what you want to find and set up equations to represent each sentence.
As seen there are hamburgers and chickens in this problem. So let's set the numbers of hamburgers to x, and the numbers of chickens to y.
Now write out each sentence using variables.
1.) Tia sold 78 hamburgers and chicken tenders.
x+y=78
2.) If she sold 24 more hamburgers than chicken tenders.
x=y+24
Now that we have the 2 equations, its time to solve.
Since we have x=y+24, we can replace the x in the first equation with the second equation
y+24+y=78
2y+24=78
Now we can subtract 24 from both sides.
2y=54
Simplify
y=27
Solve for x
x=27+24=51

1. Savannah has 5 dogs and she feeds each of them 6 oz of dog food every day. How many
pounds of dog food do they eat each day?
Answers
Answer:
0.375 lb
Step-by-step explanation:
For this one all you need to do is convert 6 oz to pounds and to do this
For example to convert an ounce measurement to a pound measurement, use a simple formula. Since one ounce is equal to 1/16 of a pound, the formula for the conversion is:
pounds = ounces ÷ 16
1. Take measurement
2. Divided ounces by 5
3. Round the result to desired decimal places.
And don't just put this answer because I am not very sure.
1.875 pounds of dog food can be eaten by 5 dogs per day.
Pound and ounce based problem:What information do we have?
Number of dogs = 5
Each dog eats per day = 6 oz
Total dog food eaten per day = Number of dogs × Each dog eats per day
Total dog food eaten per day = 5 × 6
Total dog food eaten per day = 30 oz
1 pound = 16 oz
So,
Total dog food eaten per day = 30oz / 16oz
Total dog food eaten per day = 1.875 pound

PLEASE HELP FAST(solve the pre-algebra question)
Answers
Answer:
Flag = 46
Shamrock = 46
Hat = 27
Accordion = 198
Step-by-step explanation:
To keep things simple, I'll denote the flag with f, the shamrock with s, the hat with h and the accordion with a.
The second equation tells us that f/s is 1. When you divide something by something and get 1, that means they're equal (eg, 2÷2=1, 3÷3=1 etc). That means f=s.
The second equation tells us f+s+s=138, but since f=s, this basically means 3f=138. Dividing both sides by three, we find out f=46 and by extension, s=46.
The third equation tells us s+h+h=100. We know s so we can write this as 46+2h=100. Take 46 form both sides to get 2h=54. Divide both sides by 2, we find out h=27.
The fourth equation tells us a=4f+14. Sub in our value for f and this is a=(4x46)+14. Solve this to get a=184+14, a=198.

Write the standard equation of the circle with center (-14, -3) that passes through the point (-5,3),
Answers
Answer:
[tex](x + 14)^2 + (y + 3)^2 = 117[/tex]
Step-by-step explanation:
Equation of a circle:
The equation of a circle with center [tex](x_0,y_0)[/tex] is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
In which r is the radius.
Center (-14, -3)
This means that [tex]x_0 = -14, y_0 = -3[/tex]
So
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
[tex](x - (-14))^2 + (y - (-3))^2 = r^2[/tex]
[tex](x + 14)^2 + (y + 3)^2 = r^2[/tex]
Passes through the point (-5,3),
This means that when [tex]x = -5, y = 3[/tex]. We use this to find the radius squared. So
[tex](x + 14)^2 + (y + 3)^2 = r^2[/tex]
[tex](-5 + 14)^2 + (3 + 3)^2 = r^2[/tex]
[tex]r^2 = 117[/tex]
So, the equation of the circle is:
[tex](x + 14)^2 + (y + 3)^2 = r^2[/tex]
[tex](x + 14)^2 + (y + 3)^2 = 117[/tex]
