Shiloh has to earn at least $200 to meet her fundraising goal. She has only 100 cakes that she plans to sell at 5 dollars each. Which inequality shows the number of cakes, x, Shiloh can sell to meet her goal?

Answers

Answer 1
Answer:

Answer:

40 \leq x \leq 100

Step-by-step explanation:

Cost of 1 cake = $5

Let x be the no. of cakes

So, Cost of x cakes = 5x

Since we are given that Shiloh has to earn at least $200

So, 5x\geq 200

x\geq 40

So, the no. of the cakes should be sold more than or equal to 40

We are also given that She has only 100 cakes

So, the maximum number of cakes she can sold is 100 i.e.x\leq 100

So, Inequality becomes : 40 \leq x \leq 100

Hence inequality shows the number of cakes, x, Shiloh can sell to meet her goal is 40 \leq x \leq 100
Answer 2
Answer: she will only have to sell 40 cakes to earn $200

If the vertices of triangle bcd are b(-3,3), c(3,5), and d(-1,0), what is the perimeter

Answers

distance formlula
D=\sqrt{(x2-x1)^(2)+(y2-y1)^(2)}

when you want to find the distance between points (x1,y1) and (x2,y2)


we nee
distace from
b to c
c to d
d to b


b to c is (-3,3) to (3,5)
D=\sqrt{(3-(-3))^(2)+(5-3)^(2)}=2√10

c to d is (3,5) to (-1,0)
D=\sqrt{(-1-3)^(2)+(0-5)^(2)}=√41

d to b is (-1,0) to (-3,3)
D=\sqrt{(-3-(-1))^(2)+(3-0)^(2)}=√13

add

b to c+c to d+d to b=2√10+√41+√13

perimiter=2√10+√41+√13 units

Find the Quotient. y9 divided by y3

find the quotient. 2^3 divided by 5^2

Answers

Step-by-step explanation:

y9 divided by y3

(y^9)/(y^3)

When the base of the exponent are same and they are in division then we subtract the exponents.

(y^9)/(y^3)=y^(9-3)=y^6

2^3 divided by 5^2

(2^3)/(5^2)

The exponents of base are not same, so we cannot subtract the exponents

2^3=8 , 5^2= 25

(8)/(25) = 0.32 is a decimal number
2^3/5^2= .32

I couldn't get it as exponential notation, but here is the final answer

y9/y3= y3

and these two, you just divide ad regular numbers and the insert the y
