Answer:
7 seconds
Step-by-step explanation:
The radius of a sphere-shaped balloon increases at a rate of 2 centimeters (cm) per second.
surface area of the completely inflated balloon is 784 cm²
SA=4r²
784= 4r²
784/4= r²
196 = r²
14cm = r
Yhe radius of the complete inflated balloon is 14cm
If the ball inflate at the rate of 2 cm per seconds
Then it took 14/2 = 7 seconds to inflate fully
Answer:
3/5, 30%, 0.1
Step-by-step explanation:
0.4 + 1/2 + 40% = 0.4 + 0.5 + 0.4 = 1.3
3/4 + 0.25 + 1/2 = 0.75 + 0.25 + 0.5 = 1.5
3/5 + 30% + 0.1 = 0.6 + 0.3 + 0.1 = 1
The last choice is a probability complement because all values add to 1.
16 and 1/5 is equal to 16.2
So 19.8 subtract 16.2 is equal to 3.6
Savannah is 3.6 or 3 and 3/5 seconds faster than Paloma.
Answer:
65 miles
Step-by-step explanation:
y=55+0.35x
77.75 = 55+0.35x
77.75 - 55 = 0.35x
22.75 = 0.35x
22.75 ÷ 0.35 = 0.35x ÷ 0.35
65 = x
x = 65
Answer:
hypotenuse = 13.0 cm
Step-by-step explanation:
Given the dimensions of a right triangle whose legs have measures of 13 cm and 1 cm, we can use the Pythagorean Theorem to find the measure of the triangle's hypotenuse.
The <u>Pythagorean Theorem</u> states that the squared measure of a right triangle's hypotenuse is equal to the sum of the squared lengths of its legs. In other words:
Pythagorean Theorem: c² = a² + b²
Let c = hypotenuse
a = Leg₁ = 1 cm
b = Leg₂ = 13 cm
Substitute these values into the given formula to find the measure of the hypotenuse, c:
c² = a² + b²
c² = ( 1 )² + (13)²
c² = 1 + 169
c² = 170
Next, take the square root of c² and 170 to isolate c:

c = 13.04 or 13.0 cm
Therefore, the length of the hypotenuse is 13.0 cm.
