Answer:
3h+4.50=15
We know that she skates for 3 hours, but we don't know the cost per hour so is the "h". He pays a start up $4.50 for the ice skates. And he spend $15 in total for ice skating.

the perimeter of a triangle is 31 cm sides #1 and #2 have equal length, while side #3 /is one centimeter shorter than twice the length of side #1. how long is each side?
answers are at down
Step-by-step explanation:
The perimeter of a triangle is 31 cm. Sides #1 and #2 have equal length, while Side #3 is one centimeter shorter than twice the length of Side #1. Let's determine how long each side is: a. Let x represent the length of Side #1. What essential part of this "let" statement is missing? What is the length of Side #2? Side #3? b. Write a mathematical sentence that states that the perimeter is 31 cm. c. Solve the equation you found in part (b) and determine the length of each side. Be sure to label your answers with the appropriate units.
Answer:
8 cm, 8 cm, 15 cm
Step-by-step explanation:
The given relationships between the sides can be used to write an equation. Let s represent the length of side 1. Then side 2 has a length that is also s. Side 3 has length (2s-1). The perimeter is the sum of the side lengths:
s + s + (2s -1) = 31
4s = 32 . . . . . . . . . . collect terms, add 1
s = 8 . . . . . . . . . . divide by 4
(2s -1) = 2·8 -1 = 15

Answer:
The distance between -1,12 and -1,-3 is 15
Step-by-step explanation:
Simplify-
Multiply −1 by −1.
√(−1+1)^2 + ((−3) −12)^2
Add −1 and 1.
√0^2 + ((−3) −12)^2
Raising 0 to any positive power yields 0.
√0 + ((−3) −12)^2
Subtract 12 from −3.
√0 + (−15)^2
Raise −15 to the power of 2.
√0 + 225
Add 0 and 225.
√225
Rewrite 225 as 15^2.
√15^2
Pull terms out from under the radical, assuming positive real numbers.

What is exponential growth or decay function?Consider the function:
[tex]y = a(1\pm r)^m[/tex]
where m is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
We have been given that a bike tire just ran over a nail, and it is losing pressure at a rate of 10% every minute. The tire pressure is currently 1,060 kilo-pascals. We are asked to find the tire pressure in 4 minutes.
We will use exponential decay formula to solve our given problem.
[tex]y = a(1\pm r)^m[/tex]
Let us convert 10% into decimal.
0.01
Initial value is 1,060 . Upon substituting our given values in above formula, we will get:
y = 1,060 (1 - 0.01)^4
Therefore, the tire pressure will be approximately 40% kilo-pascals in 4 minutes.

Answer:
x = 5, x = 7
Step-by-step explanation:
tangents from an external point to a circle are congruent , then
x² = 12x - 35 ( subtract 12x - 35 from both sides )
x² - 12x + 35 = 0
(x - 5)(x - 7) = 0
equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
x - 7 = 0 ⇒ x = 7

13 A cuboid has a volume of 24 cm. What is its base
area if it has a height of 3 cm?
Answer:
8 cm²
Step-by-step explanation:
Since the Volume of Cuboid = Base Area * Height
Then 24=Base Area * 3
Base Area = 24/3 = 8 cm²
Answer:
8
Step-by-step explanation:
24 = volume
3 = height
24/3 = 8, is the base area.
A basketball player is shooting a basketball toward the net. The height, in feet, of the ball t seconds after the shot is modeled by the equation h = 6 30t – 16t2. Two-tenths of a second after the shot is launched, an opposing player leaps up to block the shot. The height of the shot blocker’s outstretched hands t seconds after he leaps is modeled by the equation h = 9 25t – 16t2. If the ball was on a path to reach the net 1. 7 seconds after the shooter launches it, does the leaping player block the shot? yes, exactly 0. 6 seconds after the shot is launched yes, between 0. 64 seconds and 0. 65 seconds after the shot is launched yes, between 0. 84 seconds and 0. 85 seconds after the shot is launched no, shot not blocked.
The shot was blocked between 0.84 and 0.85 seconds after the shot is launched.
what will be the time in which the blocker will block the ball?The given equation for ball height
[tex]=6+30t-16t^{2}[/tex]
The equation for the blocker's height will be
[tex]=9+25t-16t^{2}[/tex]
But, the shot is made before two-tenths of a second or 0.2 seconds therefore modified equation for ball height is
[tex]=6+30(t-0.2)-16(t-0.2)^{2}[/tex]
Now for the shot to be blocked, the height of the shot-blocker must be greater than the height of the ball which is shot before 0.2 seconds :
[tex]9+25t-16t^{2} \geq 6+30(t-0.2)-16(t-0.2)^{2}[/tex]
[tex]9+25t-16t^{2} \geq6+30t-6-16(t^{2} -0.4t+0.04)[/tex]
[tex]9+25t-16t^{2} \geq30t-16t^{2} -6.4t+0.64[/tex]
[tex]9+25t\geq36.4t-0.64[/tex]
[tex]9.64\geq11.4t[/tex]
[tex]t \leq \dfrac{9.64}{11.4}=0.846[/tex]

1.) Simplify the expression by combining like
terms: a + 2a - 3a.
Answer: 0
Step-by-step explanation:
We can start by factoring out an a from all 3 terms:
= a (1 + 2 - 3)
We can evaluate 1 + 2 - 3 as 0:
= a(0)
Anything multiplied by 0 is 0, therefore 0a = 0.
