A gardener can trim a square lawn of side 50 metres in 4 hours. At the same rate, how long will it take him to trim a square lawn of side 25 metres?

A)1 hour
B)2 hours
C)2 hours 30 minutes
D)3 hours

Answers

Answer 1

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

Answer 2
2hours because 25 is half of 50 and two is half of four

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

Answers

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.

Which facts could be applied to simplify this expression? Check all that apply.

5 x + 3 y + (negative x) + 6 z

Answers

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.

x2 - 400
The factored form of x2 - 400 is

Answers

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).

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.

Answers

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.
