Answer:
91
Step-by-step explanation:
90.5 needs to be a whole number, and if it ends in 5 you round it up
You dont have a picture so idk the answer but its most likely E if thats an answer choice.
Step-by-step explanation:
2x × 3x +(-5×1)=6x-6=o
Answer:
The answer is below
Step-by-step explanation:
a) The graph is attached
b) The table shows a linear relationship between x and y.
A linear equation is in the form y = mx + b, where y is a dependent variable, x is an independent variable, m is the rate of change (slope) and b is the value of y when x = 0.
x represent the distance on map in mm and y represent the actual distance in mile. The table (x, y) has the points (10, 25) and (20, 50). The equation is given by:
![y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-25=\frac{50-25}{20-10} (x-10)\\\\y-25=2.5(x-10)\\\\y-25=2.5x-25\\\\y=2.5x](https://tex.z-dn.net/?f=y-y_1%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20%28x-x_1%29%5C%5C%5C%5Cy-25%3D%5Cfrac%7B50-25%7D%7B20-10%7D%20%28x-10%29%5C%5C%5C%5Cy-25%3D2.5%28x-10%29%5C%5C%5C%5Cy-25%3D2.5x-25%5C%5C%5C%5Cy%3D2.5x)
The slope m = 2.5. This means that for every 1 mm on the map, the actual distance increases by 2.5 miles.
c) y = 2.5x
put x = 48 mm
y = 2.5(48)
y = 120 miles
The actual distance between Toledo and Columbus is 120 miles
d) y = 2.5x
Put y = 225 miles
225 = 2.5x
x = 225/2.5
x = 90 mm
The distance on map between Cincinnati and Cleveland is about 90 mm.
Answer:
c = 12.73
Step-by-step explanation:
a^2 + b^2 = c^2
9^2 + 9^2 = c^2
81 + 81 = c^2
162 = c^2
c = ![\sqrt{162}](https://tex.z-dn.net/?f=%5Csqrt%7B162%7D)
c = 12.7279221
c = 12.73
