Answer:
1.1995
2.114.4
3.270
Step-by-step explanation:
1. Multiply the length and width
2. Multiply 14.3*8
3. Multiply 15*36 and divide the product by 2
to find the area of a rectangle, multiplty length times width
for the area of a triangle, multiply the bottom of the triangle by the height and divide it by 2.
His car gets 21 mpg (miles per gallon). With 1 gallon he can drive 21 miles. For example, with 10 gallons, he can drive 21 mpg * 10 gal = 210 miles.
He bought $19.50 worth of gas at $1.40 per gallon.
$19.50 / ($1.40/gal) = 13.93 gal
He already had 5 gal of gas in his tanks, so now he has
5 gal + 13.93 gal = 18.93 gal
With 18.93 gal, he can drive
18.93 gal * 21 mpg = 292.5 miles
Answer:
-15 is how many tests per hour i think, and 78 is how many tests total
Step-by-step explanation:
= 78 − 15ℎ
1 hour would be
78-(15x1)=63
2 hours would be
78-(15x2)=48
and so on.
Answer:
C
Step-by-step explanation:
From the graph you can see that y changes from -2 to 2, so the range of the function is ![[-2,2].](https://tex.z-dn.net/?f=%5B-2%2C2%5D.)
Since the range of the functions 
and 
is ![[-1,1]](https://tex.z-dn.net/?f=%5B-1%2C1%5D)
and the range of the functions 
and 
is ![[-k,k],](https://tex.z-dn.net/?f=%5B-k%2Ck%5D%2C)
we can state that the correct option is C:
