Work out (5.32 x 10^-7): (2.5 x 10^-5)
Give your answer in standard form
Answer:
1.33×10^-6
Step-by-step explanation:
5.32 x 10^-7= 5.32×10^(-5-2)= 5.32×10^-2×10^(-5)
=0.0532×10^-5
(0.0532×10^-5) (2.5 x 10^-5)
0.0532×2.5 × 10^-5
0.133×10^-5= 1.33×10^-1 ×10^-5

Hockey teams are often confronted with the dilemma of whether or not to pull a goalie at the end of the game when they are down a goal or two. One analyst reports that in 40% of those games in which a goalie was pulled a goal was scored with one empty net, and of those goals scored 25% were scored by the team that pulled the goaltender. Given that the goalie has been pulled by a team, what is the probability that team will score a goal?
Answer:
Step-by-step explanation:
so 30% of the total number of goals shot is 5
30% of what number is 5....turn ur percent to a decimal..." of " is multiply
let the number of shots represent x
0.30x = 5...divide borh sides by 0.30
x = 5/0.30
x = 16.66 shots

A 36-foot long rope is tied from the top of a pole to a stake in the ground. If the stake is 17 feet from the base of the pole, find the height of the pole. Round to the nearest tenth if necessary.
Answer:
Perpendicular = 31.73 ft (Approx)
Step-by-step explanation:
Given:
Length of rope (Hypotenuse) = 36 ft
Base = 17 ft
Find:
Height of pole (Perpendicular)
Computation:
Perpendicular = √Hypotenuse² - Base²
Perpendicular = √36² - 17²
Perpendicular = √1,296 - 289
Perpendicular = 31.73 ft (Approx)

The expressions which is equal to 10⁵ are 10³. 10² and 10 . 10 . 10 . 10 . 10.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
The given expression is 10⁵.
(10⁴)¹ = 10⁴
We have a rule of exponents,
xᵃ . xᵇ = xᵃ⁺ᵇ
10³. 10² = 10³ ⁺ ² = 10⁵
1 / 10⁵ = 10⁻⁵
(10³)² = 10^(3 × 2) = 10⁶
10 . 10 . 10 . 10 . 10 = 10⁵
Hence the equivalent expressions are 10³. 10² and 10 . 10 . 10 . 10 . 10.

What has to happen for scales to be balanced?
Answer:
When the pans contain exactly the same mass the beam is in balance. ... You can place an object in one pan and standard weights in the other to find what the object weighs. Here balance scales are used to show that the box "x" has a mass of 4
Answer:
a balances measure mass, while scales measure weight. So if you bring a balance and a scale to the moon, the balance will accurately give you the mass of, say, a moon rock, whereas the scale will be affected by the gravity. A balance determines mass by balancing an unknown mass against a known mass.
