C squared = 4.5 squared + 9 squared
C squared = 20.25 + 81
C squared = 101.25
Square root 101.25 you get 10.06 round up and you get the answer to be number 1
According to the pythagora theorum,
h² = a² + b²
h² = 4.5² + 9²
= 20.25 + 81
thus, h² = 101.25
thus, h = √101.25
thus, h = 10.06230589 units, or 10.1 rounded to the nearest tenth

The hummingbird will take 1 minute 13 seconds.
Let the time that will be taken by the hummingbird be represented by x
Note that 1 minute = 60 seconds
Based on the information given, the equation that'll be used in the question will be:
45/55 = 60/x
Cross multiply
(45 × x) = (60 × 55)
45x = 3300
x = 3300/45
x = 73.33 seconds
x = 1 minute 13 seconds
The hummingbird will take 1 minute 13 seconds.

Answer:
1 2/9 minutes
Step-by-step explanation:
55 mph
55 / 60 = 11/12
11/12 of a mile = 1 minute
45 mph
45 / 60 = 3/4
3/4 of a mile = 1 minute
11/12 divided by 3/4
11/12 * 4/3
We can cross-cancel
11/3 * 1/3 = 11/9 = 1 2/9
It takes 1 2/9 minutes for the hummingbird to cross the lake

180(n-2)
180 x 2 = 360
Therefore, the sum of the angles must be 360.
56 + 97 + 136 = 289
360 - 289 = 71°

What number should the equation y = x − 4 be multiplied by to eliminate x?
Answers
The Mindy should multiplied the second equation with number 2 to elminate the x term and solve the system using the elimination method.
What is elemination method?
The elemination method is used to solve the system of equation and to find the values of unknown variable.
To solve the equations using the elemination method, follow the following steps-
- Multiply all the equation, with a number such that the one of the comon variable of both the equation gets the same coefficient.
- Substract the equations to elminate one of the variable.
- Solve the equation for remaining variable.
- Substitude the value of this variable in any equation to find the value of other variable.
The system of equation, Mindy wants to solve using the elimination method are,
To perform the elemation method, the terms of varible of x in both the equation should be same.
The coefficient of x in second equation is 2. Thus, the equation y = x − 4 should be multiplied by 2 to eliminate x.
Hence, the Mindy should multiplied the second equation with number 2 to elminate the x term and solve the system using the elimination method.

1ft³=0.5 tons
Cross multiply
1x=13.5tons
x=13.5tons
So one scoop/load carries 13.5 tons of sand. Lets see how many 120 loads can carry.
13.5tons*120loads=1620 tons of sand
Now lets see how freight cars it would take to hold 1620 tons of sand
1620/40=40.5 freight cars
Since you can't have .5 of a freight car, lets round 40.5 up to 41
Answer=41 freight cars
