Answer:

Step-by-step explanation:

A ladder 5 meters long leans against a wall. The top of the ladder is 4 meters above the ground. The

ladder makes an approximate angle of 53° with the ground. This will not be correct because in the process of calculating the angle , we have

tanФ = 10/6.2

= 1.6129

Ф = $tan^{-1}$ 1.6129

= 58.20

And it was not mentioned in the statement that the angle was approximated.

2. A ladder 5 meters long leans against a wall. The top of the ladder is 4 meters above the ground. The

ladder makes an approximate angle of 53° with the ground. This is correct , because the calculation will give an approximate answer of 53

3. A ladder 6 meters long leans against a building. The ladder makes an angle of 60' with the ground. The

ladder reaches approximately 5.2 meters up the wall. This is also correct because the calculation will give an approximate answer of 5.2

(Solving Equations) Ken has $20.00. Coffee costs $4.79 per pound. Which equation will calculate the number of pounds of coffee,

aev [14]

Answer: A. 4.79(n)=20.00

Step-by-step explanation:

we need to find what amount of coffee (per pound) is equivalent to $20.00

so we take the unknown amount (n) and multiply it by $4.79

for example, say Ken wants 4 pounds, we need to know if it is equivalent to $20.00

so take 4.79 and multiply it by 4 to see if it is equal to or less than $20.00 in this case $4.79 x 4 = $19.16

hope this helps (^_^)

n ΔABC, if the length of sides a, b, and c are 3.5 centimeters, 5.5 centimeters, and 6 centimeters respectively, what is m∠C to

borishaifa [10]

We are given with three sides with measurements such as below:
a = 3.5 cm
b = 5.5 cm
c = 6 cm
We are asked to solve for m∠C. To solve this we need to apply Law of Cosines such as below:
cos C = a²+b² - c² /2ab
cos C = 3.5² + 5.5² -6² / (2*3.5*5.5)
cos C = 0.16883
C = 80.28°

Open-Ended Question<br>*Picture*

My name is Ann [436]

We have to calculate the volume of the right rectangular prism.
lenght=4 1/2 in=(4+1/2) in=9/2 in
width=5 in
height=3 3/4 in=(3+3/4) in=15/4 in

Volume (right rectangular prism = lenght x width x height.
volume=9/2 in * 5 in * 15/4 in=675/8 in³

we calculate the volume of this little cube.
volume=side³
volume=(1/4 in )³=1/64 in³

Now, we calculate the number of small cubes are needed to fit the right rectangular pris by the rule of three.

1 small cube----------------1/64 in³
x---------------------------------675/8 in³

x=(1 small cube * 675/8 in³) / 1/64 in³=5400 small cubes.

Answer: we need 5400 small cubes to fit the right rectangular prism.
