Mary bakes a chocolate cake, a vanilla cake, and a strawberry cake. Each cake is the same size. Angela eats four-eighths of the chocolate cake, two-eighths of the vanilla cake, and two-fourths of the strawberry cake. David eats one-fourth of the chocolate cake, three-eighths of the vanilla cake, and one-half of the strawberry cake. Who eats more cake, Angela or David? How much more cake? How much of each cake is left? Show all your mathematical thinking.
Answer:
Angela eats more cake
Angela ate 1/8 more cake
1/4 of the chocolate
3/8 of the Vanilla
no more Strawberry
Step-by-step explanation:
Angela: 4/8 + 2/8 + 4/8 = 10/8 = 1 1/4
David: 2/8 + 3/8 +4/8 = 9/8 = 1 1/8
Chocolate: 4/8 + 2/8 = 6/8, 8/8 - 6/8 = 2/8 or 1/4
Vanilla: 2/8 + 3/8 = 5/8, 8/8 - 5/8 = 3/8
Strawberry: 4/8 + 4/8 = 8/8, 8/8 - 8/8 = 0
Final answer:
Angela ate more cake than David by 0.125 of a cake after calculating fractions consumed by each. The remaining amounts of cake are 1/4 of chocolate, 3/8 of vanilla, and none of the strawberry cake is left.
Explanation:
To find out who eats more cake, Angela or David, we need to calculate the fractions of each cake they consumed. Firstly, we can simplify the fractions of the cake Angela and David ate by converting them to have the same denominator or to represent them as decimals. The total amount of each cake consumed needs to be added up individually for Angela and David.
Angela's Cake Consumption:
Chocolate Cake: 4/8 (simplified to 1/2 or 0.5)
Vanilla Cake: 2/8 (simplified to 1/4 or 0.25)
Strawberry Cake: 2/4 (simplified to 1/2 or 0.5)
Total cake eaten by Angela = 0.5 (chocolate) + 0.25 (vanilla) + 0.5 (strawberry) = 1.25
David's Cake Consumption:
Chocolate Cake: 1/4 (or 0.25)
Vanilla Cake: 3/8 (simplified to 0.375)
Strawberry Cake: 1/2 (or 0.5)
Total cake eaten by David = 0.25 (chocolate) + 0.375 (vanilla) + 0.5 (strawberry) = 1.125
Angela ate more cake than David by 0.125 of a cake.
Amount of Each Cake Left:
Chocolate Cake: 1 - (0.5 + 0.25) = 1/4 or 0.25 left
Vanilla Cake: 1 - (0.25 + 0.375) = 3/8 or 0.375 left
Strawberry Cake: 1 - (0.5 + 0.5) = 0 left

5x - 3y = -15 solve for y
Answer:
y = 5/3 x + 5
Step-by-step explanation:
5x - 3y = -15
Subtract 5x from each side
5x-5x - 3y = -15-5x
-3y = -5x-15
Divide each side by -3
-3y/-3 = -5x/-3 -15/-3
y = 5/3 x + 5
To solve 5x - 3y = -15 for y, you need to isolate y, by adding 5x to both sides and then dividing by -3, yielding the solution y = -5x/3 + 5.
Explanation:To solve the equation 5x - 3y = -15 for y, we need to isolate y on one side of the equation. Here's a step-by-step process:
Move the term with x to the other side by adding 5x to both sides of the equation. This gives us -3y = 5x - 15.Now, divide every term by -3 to solve for y. Doing this, we get y = (5x - 15) / -3.Simplify the equation which gives us y = -5x/3 + 5. This is our solution for y in terms of x.Using this method, we can solve any linear equation in two variables for one of the variables. In this case, we have expressed y as a function of x.

Answer:
The center is [tex](-4,5)[/tex] and the radius is [tex]11[/tex].
Step-by-step explanation:
The center-radius form for a circle is:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
where [tex](h,k)[/tex] is the center and [tex]r[/tex] is the radius.
Compare:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
[tex](x+4)^2+(y-5)^2=121[/tex]
[tex]-h=4[/tex] implies [tex]h=-4[/tex].
[tex]-k=-5[/tex] implies [tex]k=5[/tex]
[tex]r^2=121[/tex] implies [tex]r=\sqrt{121}=11[/tex].
The center is [tex](-4,5)[/tex] and the radius is [tex]11[/tex].
The center is (-4.5) and the radius is 11.
How to find the center and radius of the circle?The center-radius form for a circle is:
⇒ (x-h)²+(y-k)² = r²
where (h,k) is the center and r is the radius.
Compare:
(x-h)²+(y-k)²
(x+4)+(-5)² = 121
-h = 4 implies h = -4.
-k = -5 implies k = 5
r² = 121 implies r = √121= 11,
The center is (-4.5) and the radius is 11.
The center is a fixed point in the middle of the circle; usually given the general coordinates (h, k). The fixed distance from the center to any point on the circle is called the radius.
