Answer:
a)
b) SSA does not constitute a proof. You need another fact.
Step-by-step explanation:
You should actually show congruency first
Angles opposite = sides are themselves equal.
<C = 50o
<J = 50o
But there is nothing that says x is 1/2 of <JAC
So it's unsolvable
Part B also has the same conclusion.
Answer:
24
Step-by-step explanation:
First we must recognize that this equation is a quadratic function, therefore we can use the quadratic equation and look only at the discriminate portion of that formula. However, before doing so we need to set up our equation by taking the 1 to the other side and so:
And we know that in general a quadratic function is such that:
And so our quadratic equation is:
But we only need to look at what's under the square root meaning:
This is our discriminant and since a=5, b=2 and c=-1 we have:
Answer:
B) 72
Step-by-step explanation:
28+(17x+4)=4+24x
17x+32=24x+4
32=24x-17x+4
32=7x+4
7x=32-4
7x=28
x=28/7
x=4
WGH=17x+4=17(4)+4=68+4=72
Answer:
re order is 90 bottles
Step-by-step explanation:
given data
shampoo in stock = 50 bottles
reserve = 35
stock record = 4 week
delivery = 3 week
average sale = 15 / week
to find out
what should be re ordered
solution
according to question we know that total week for order is
total week for order = 4 + 3 = 7 week
so total sale in 7 week is = 7 × average sale
total sale in 7 week = 7 × 15 = 105 bottles
and
he need more bottle = total sale - in stock
need bottle = 105 - 50
need bottle = 55
so order = need bottle + reserved bottle
order = 55 + 35
order = 90 bottles
so re order is 90 bottles
