The price that a company charged for a computer accessory is given by the equation 100-x^2 where x is the number of accessories

Setler79 [48]

Answer:

1.45 million accessories

Step-by-step explanation:

we need to write an algebraic equation

y = (100 - 10x^2)x - 10x

y represents the profit

x represents the # of accesories produced in millions

I used 10 because that's the cost of making each accessory

100-x^2=consumer price

x-10x= accessory-cost to make all the accessories

we know that 2 million accessories make 100 million

so the number of accessories that approximately make 100 should be around 2 million

in the options 1.45 is given which is close to 2

even though 3.45 is closer than two you would go beyond a 100 million profit which isn't what you want

if the options weren't given you would have to use all values from 1-2 as "x"

hope this helps!

Dennis and Ivy share some sweets between them in the ratio 7:4 Dennis got 42 sweets. How many does ivy get

MrRa [10]

Answer:

$Ivy = 24$

Step-by-step explanation:

Given

$Dennis : Ivy = 7 : 4$

Required

Determine the amount of sweet Ivy gets when Dennis = 42

We have:

$Dennis : Ivy = 7 : 4$ and

$Dennis = 42$

Substitute 42 for Dennis in $Dennis : Ivy = 7 : 4$

$42 : Ivy = 7 : 4$

Convert to fraction

$\frac{42}{Ivy} = \frac{7}{4}$

Cross Multiply:

$Ivy * 7 = 42 * 4$

Divide through by 7

$\frac{Ivy * 7}{7} = \frac{42 * 4}{7}$

$Ivy = \frac{42 * 4}{7}$

$Ivy = 6* 4$

$Ivy = 24$

Alexandra uses 12 cups of water and 6 cups of dry rice to make 18 cups of cooked rice. Today, she wants to make 4 cups of cooked

LekaFEV [45]

The proportion that Alexandra can use to find r is 9 cups of water and 4 cups of dry rice

If Alexandra uses 12 cups of water and 6 cups of dry rice to make 18 cups of cooked rice, this can be expressed as:

$\frac{12}{6} = 18cups$

To get the proportion "r" for the amount of dry rice to use to make 4 cups of cooked rice, we can write:

$r = 4 cups$

Divide both expressions:

$\dfrac{\frac{12}{6} }{\frac{a}{b} } =\frac{18}{4}\\\dfrac{12b}{6a}= \frac{18}{4}\\\dfrac{2b}{a} =\frac{18}{4}\\\frac{b}{a} =\frac{18}{8}\\\frac{b}{a} =\frac{9}{4} =r$

Hence the proportion that Alexandra can use to find r is 9 cups of water and 4 cups of dry rice

Circle o is inscribed in triangle rst such that it is tangent at points m,n, and p. if rp is 7, rt is 17 and sm is 5, then what

goldenfox [79]

Answer:

Step-by-step explanation:

Tangents to the circle from the same point are the same length. Then rn = 7, and nt = 10. This means mt = 10, so ...

st = sm +mt = 5 +10

sm = 15
