Convert the function into standard form. Show your work. y-2=-3(x+4)^2
Sonja [21]

Answer:

y = -3x² - 24 x + 50

Randi and her sister make balloon animals and sold them for $.50 each. They made $48.00. If rando made twice as many animals as
nydimaria [60]

Randy made 64 ballon animals and her sister made 32 ballon animals

<em><u>Solution:</u></em>

Let the number of ballon animals sold by Randi be "x"

Let the number of ballon animals sold by her sister be "y"

Cost of 1 ballon animal = $ 0.50

<em><u>Rando made twice as many animals as her sister</u></em>

Number of ballon animals sold by Randi = twice the number of ballon animals sold by her sister

x = 2y ---- eqn 1

<em><u>Together, they earned $ 48</u></em>

Therefore, we can frame a equation as:

Number of ballon animals sold by Randi x Cost of 1 ballon animal + number of ballon animals sold by her sister x Cost of 1 ballon animal = 48

2y \times 0.50 + y \times 0.50 = 48

1y + 0.5y = 48\\\\1.5y = 48\\\\y = \frac{48}{1.5}\\\\y = 32

<em><u>Therefore, from eqn 1</u></em>

x = 2y

x = 2(32)

x = 64

Thus Randy made 64 ballon animals and her sister made 32 ballon animals

Hi! I’m stuck on this problem on math! This is 5th grade math. Can anyone help me?
emmasim [6.3K]

Answer:

The answer is 4.2 kilograms of dog food

Step-by-step explanation:

it says that ray feeds his dog 0.12 kilogram of food each day

he needs for 1 month

1 month = 31 days or 30 days

since 1 day food is 0.12 kilograms you'll have to multiply 0.12 with 1 month

i.e; 0.12*31 or 0.12*30

0.12*31=3.72 and 0.12*30=3.6

since we don't have an option we'll have to choose something bigger than this

therefore, the answer is 4.2
