Pythagoras Theorem:
hipotenuse²=side1² +side2²
a=is the longest side of the triangle (hypotenuse)
b and c: are the other two sides.
In this case:
hipotenuse²=side₁² + side₂²
side₁=a=16
side₂=b=28
c²=16²+28²
c²=256+784
c²=1040
c=√1040=32.2490....≈32.25
Answer: D. 32.25
Answer:
$30
Step-by-step explanation:
She paid $24.72 for the 2 packages of chicken because $12.36×2=$24.72.
She paid $0.99 for the broccoli because $1.98×1/2=$0.99.
She paid $3.49 for the milk because one gallon of milk costs $3.49.
$24.72+$0.99+$3.49=$29.20.
$29.20+$0.80=$30.00.
She used $30.00 to pay for the items.
Answer:
Factoring
Step-by-step explanation:
x^2 + 7x = x(x + 7) = 0
So
x = 0 or x = -7
Answer: the plain pencil costs 10 cents and the colored pencil costs 20 cents
Answer
y = 0.2x − 7
Step-by-step explanation:
Find the slope first by subtracting (10, -5) and (5, -6) in slope formula, this will equal 1/5 or 0.2
Then find the y-intercept which is the point that crosses the y-axis, in this case -7 is the y-intercept
Finally format in y=mx + b for slope-intercept form
y=0.2x-7
