3) A Hotel has 260 rooms-some singles and some doubles. The singles cost $35 per night and the doubles cost $60 per night. During a Packers game weekend all rooms were occupied. The sales for the night were $14,000. Johnny wrote the following system but forgot to define the variable with let statements x + y = 260 { 60x + 35y = 14000 a. Use words to write the let statements for Johnny's system: i. Let I= ii. Let y b. Solve Johnny's system

its a, i had the same answer, its from study island right

step-by-step explanation:

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough

the forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?
