Answer:
2 hours
Step-by-step explanation:
50 metres / 4 hours = 25 metres / x hours
cross multiply both sides
50x = 25(4)
50x = 100
divide 50 both side
x = 100/50
x = 2 hours

Find the percent of change from 74 hours to 85 hours.
Answer:
The answer would be 14.8645, but it'd be repeating, so it's actually 14.864864864864865.
I think you should write the entire number down just in case.
I'm so sorry. It would be a percent increase, so it's a positive.

Factor the difference of squares.
x2 - 400
The factored form of x2 - 400 is
Answer:
The factored form of x²-400 is (x+20)(x-20).
Step-by-step explanation:
Given the expression
[tex]x^2\:-\:400[/tex]
As the square of 20 is 400. Therefore, rewrite 400 as 20²
⇒ [tex]x^2-20^2[/tex]
[tex]\mathrm{Apply\:Difference\:of\:Two\:Squares\:Formula:\:}x^2-y^2=\left(x+y\right)\left(x-y\right)[/tex]
Thus, the expression becomes
[tex]x^2-20^2=\left(x+20\right)\left(x-20\right)[/tex]
Thus, the factored form of x²-400 is (x+20)(x-20).

Question 8 (5 points)
(02.07 MC)
In the figure shown, what is the measure of angle x? (5 points)
150 degrees
110 degrees
105 degrees
100 degrees
Given:
Consider the below figure attached with this question.
To find:
The value of x.
Solution:
According to the exterior angle theorem, the exterior angle of a triangle is equal to the sum of two opposite interior angles.
In triangle ABC, using exterior angle theorem, we get
[tex]\angle ACD=\angle ABC+\angle BAC[/tex]
[tex]x=75^\circ +30^\circ [/tex]
[tex]x=105^\circ [/tex]
The value of x is 105 degrees.
Therefore, the correct option is C.

Thomas draws a triangle with side lengths of 5 centimeters and 12 centimeters and one angle of 90°. The length of the longest side of the triangle is not known. How many different triangles can be drawn with these dimensions? Explain your reasoning.
Step-by-step explanation:
Thomas draws a triangle with side lengths of 5 centimeters and 12 centimeters and one angle of 90.
If one of the angle is 90 degrees, it would mean that he has drawn a right angle triangle.
Hypotenuse is the longest side of the triangle. We can find it using Pythagoras theorem as follows:
[tex]h=\sqrt{5^{2}+12^{2}}\\\\=13[/tex]
The longest side is 13 cm.
If we keep the longest side the same and if two sides i.e. 5 cm and 12 cm are replaced, a new triangle can form.

[tex]\huge\boxed{\sf \frac{-16}{147} }[/tex]
Step-by-step explanation:
Multiplicative Inverse of [tex]\sf 3\frac{1}{2} (\frac{7}{2} )[/tex] = [tex]\sf \frac{2}{7}[/tex]
Multiplicative inverse of any number is the reciprocal of that number.
Additive inverse of [tex]\sf 2\frac{5}{8}(\frac{21}{8} )[/tex] = [tex]\sf -\frac{21}{8}[/tex]
Additive Inverse of any number is the number that has the opposite sign.
Solution:
[tex]\sf \frac{2}{7} / - \frac{21}{8} \\\\\frac{2}{7} * - \frac{8}{21} \\\\= \frac{2*(-8)}{7*21} \\\\= \frac{-16}{147} \\\\\rule[225]{225}{2}[/tex]

Which facts could be applied to simplify this expression? Check all that apply.
5 x + 3 y + (negative x) + 6 z
Answer:
The answer is B, C, and D. Like terms are terms with all the same variable, so 5x and -x are like terms.
C is correct. If we add -x to 5x, we get 4x. The other numbers remain unchanged because they have no like terms.
D is correct. Applying the rule of like terms, which is that like terms are numbers with the same variable, only add together numbers with the same variable.
