Answer:
An equation that is satisfied for every value of the variable for which both sides of the equation are defined is called an identity. Conditional equations are true for some values of the variable and false for others. Contradictions are false for all values of the variable.

Answer:
B
Step-by-step explanation:
when the arrow is pointing toward the left side that means less than side. When the arrow is pointing towards the right side that means greater than.
Answer:
B, because that symbol means at least so you would go to the negative side which is on the left it has to start from 4 which is correct and this means negative: - The 0 is the origin so from the origin to the left side is negative from the origin to the right side is positive you want to look for negative because it's negative 4.
In ΔFGH, g = 7.6 inches, h = 3.2 inches and ∠F=160°. Find the length of f, to the nearest 10th of an inch.
In ΔFGH, g = 7.6 inches, h = 3.2 inches and ∠F=160°. Find the length of f, to the nearest 10th of an inch.
=10.7
The length of f from the given triangle FGH is 10.7 inches.
What is cosine rule?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them. The law of cosine states that: a² = b² + c² − 2bc·cosA.
Given that, in ΔFGH, g = 7.6 inches, h = 3.2 inches and ∠F=160°.
Here, f² = 7.6² + 3.2² − 2×7.6×3.2×cos160°
f² = 57.76+10.24-48.64×(- 0.9396)
f² = 68+45.70
f² = 113.7
f = √113.7
f = 10.7 inches
Therefore, the length of f is 10.7 inches.

The distance from Charles's house to his school is 3 miles. His father gave him a ride for 1,760 yards, and he walked the rest of the way. The distance that Charles walked is miles or yards. (Hint: 1 mile = 1,760 yards.)
Answer:
2 miles or 3520 yards
Step-by-step explanation:
The distance from Charles's house to his school is 3 miles. His father gave him a ride for 1,760 yards, and he walked the rest of the way. The distance that Charles walked is miles or yards. (Hint: 1 mile = 1,760 yards.)
From the Question, we know that
1 mile = 1,760 yards..
His father gave him a ride for 1,760 yards,
Hence, the number of miles Charle's father drove him was 1 mile
The distance that Charles walked in miles is calculated as:
3 miles - 1 mile
= 2 miles
Converting to yards
1 mile = 1,760 yards..
2 miles = x
Cross Multiply
x = 2 × 1760 yards
= 3520 yards

The triangles are similar . What is the value of X
Answer:
16
Step-by-step explanation:
There are 2 different ways to solve this
1) The bigger triangle is 4 times bigger than the smaller one
5 x 4 = 20
3 x 4 = 12
From this method you can see they all connect so you take the smaller triangles value of 4 and multiply it by 4
4 x 4 = 16
2) Pythagorean theorem and reorganizing the formula so that the a value is found
[tex]a = \sqrt{c^{2} -b^{2} }[/tex]
A village is 10km on a bearing 050° from a point O. Calculate how far the village is north of O.
Answer:
7.66 km
Step-by-step explanation:
Let distance village is ; north of O = x
Using Pythagoras rule :
Sinθ = opposite / hypotenus
Opposite = x
Hypotenus = 10
θ = 50°
Sin50 = x / 10
0.7660444 = x / 10
x = 0.7660444 * 10
x = 7.6604444
x = 7.66
