4. An equilateral triangle has a perimeter of 60 cm. Find the exact
altitude of the triangle.
Step-by-step explanation:
GIVEN:-The Perimeter of Equilateral triangle = 60cm
UNDERSTANDING THE CONCEPT:-According to the question,
To find the height of the triangle,
Perimeter of Equilateral triangle = Area of Equilateral triangle.
FORMULA USED:-[tex]60 = \frac{ \sqrt{3} }{4} a {}^{2} \\ [/tex]
REQUIRED ANSWER:-[tex]60 \times 4 = \sqrt{3a {}^{2} } [/tex]
[tex]a {}^{2} = 240 \sqrt{3} \\ [/tex]
[tex]a = 120 \sqrt{3} cm[/tex]

Step-by-step explanation:
work out the value of angle x, 90 degrees
Answer:
x = 45
Step-by-step explanation:
In isosceles triangles (a triangle where two sides are equal), the two base angles are congruent.
The sum of angles in a triangle is 180°.
In this problem, x is a base angle, so the other base angle is equal to x.
So, adding up all the measures of the angles in this triangle,
90 + x + x = 180
Simplify.
2x + 90 = 180
Substract 90 from both sides
2x = 90
Divide both sides by 2
x = 45
Quadrilateral ABCD is a parallelogram. What is BC?
Answer:
BC = 36 ≅ (AQ+QD)
Step-by-step explanation:
1. Identify potential angles
∠Q≅90˚ so ∠B = 60˚ + 60˚ and ∠C = 30˚+30˚
2. Two isosoceles triangle
18=AB=AQ
18=CD=DQ
3. BC = AQ+QD
BC = 18+18
BC = 36

The difference of b and 4 is at most 15.
Answer:
b - 4 ≤ 15
b ≤ 19
Step-by-step explanation:
The statement "at most" typically means no more than, so the inequality sign would have to be "less than or equal to"
To solve for be all you would do is add 4 to both sides to get b by itself.
b - 4 ≤ 15
b - 4 + 4 ≤ 15 + 4
(-4 + 4 cancels itself out)
(15 + 4 = 19)
b ≤ 19

Elroy enjoys roller skating and weight training. Let X represent the number of hours he spends roller skating weekly,
and let y represent the number of hours he spends weight training weekly. The mean of X is 5 hours, and the mean
of Y is 7 hours. Which answer choice correctly calculates and interprets the mean of the sum, S = X + Y?
Answer:
[tex]\mathbf{\mu_S = 12 }[/tex]; [tex]\text{Elroy can expect to roller skate and weight train, on average, 12 }[/tex][tex]\text{hours in a typical week.}[/tex]
Step-by-step explanation:
Given that:
The mean [tex]\mu_X = 5[/tex]
The mean [tex]\mu_Y = 7[/tex]
Where;
[tex]S= X+ Y[/tex]
[tex]\mu_S = \mu _X + \mu_Y \\ \\ \mu_S = 5+7 \\ \\ \mu_S = 12[/tex]
Thus;
[tex]\mathbf{\mu_S = 12 }[/tex];[tex]\text{ Elroy can expect to roller skate and weight train, on average, 12 }[/tex][tex]\text{hours in a typical week.}[/tex]

work out the size of angle x
Answer:
∠x = 117°
Step-by-step explanation:
supplement of ∠101° = 79°
all triangle interior angles add up to 180°
180° - 79° - 38° = 63°
the supplementary angle to 63° is 117°

Use the quadratic formula to find the solution to the quadratic equation given below. x^2-3x+9/4 =0
Answer:
[tex] x = \dfrac{3}{2} [/tex]
Step-by-step explanation:
x^2-3x+9/4 =0
Multiply both sides by 4 to get rid of the fraction.
4x^2 - 12x + 9 = 0
[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] x = \dfrac{-(-12) \pm \sqrt{(-12)^2 - 4(4)(9)}}{2(4)} [/tex]
[tex] x = \dfrac{12 \pm \sqrt{144 - 144}}{8} [/tex]
[tex] x = \dfrac{12}{8} [/tex]
[tex] x = \dfrac{3}{2} [/tex]

The volume of a cube is 125cm3.
If the cube were ice blocks, how many cubes would you need make 1KL of ice?
Answer:
8000 cubes
Step-by-step explanation:
Given that 1KL is 1 Kilo liters
Then conversion of 1KL to cm³ => 1,000,000 cm³
Therefore, since we have a cube to be 125 cm³
Hence, to find the number of cubes of ice blocks that would make 1KL
We divide 1,000,000 cm³ from 125 cm³
=> 1,000,000 ÷ 125
=> 8,000
Therefore, the correct answer is 8,000 cubes
Which of the following equations has a graph in the
xy-plane for which y is always greater than or equal
to -1 ?
A) y = |x| - 2
B) y = x2 - 2
C) y = (x - 2)2
D) y = x3 - 2
Answer: (x-2)2
Step-by-step explanation:
The required equation is [tex]y=(x-2)^2[/tex]
The correct answer is an option (C)
What is an equation?"It is a mathematical statement which consists of equal symbol between two algebraic expressions."
For given question,
We have been given four equations.
We need to find an equation for which y is always greater than or equal
to -1.
Consider,
A. y = ∣x∣ - 2
We know that the minimum value of ∣x∣ is 0.
So, the minimum value of y becomes -2
Hence, this is not a required equation.
B. [tex]y=x^{2} -2[/tex]
We know that the square of any number is always positive.
The minimum value of [tex]x^{2}[/tex] is 0.
So, the minimum value of y becomes −2
Hence, this is not a required equation.
C. [tex]y=(x-2)^2[/tex]
We know that the square of any number is always positive.
The minimum value of y is zero.
This means, the y value of equation [tex]y=(x-2)^2[/tex] is always greater than -1.
D. [tex]y=x^3-2[/tex]
We know that [tex]x^3[/tex] can go have negative values. This means it may have value that tends to negative infinity.
This means, the y can be less than -1 and this is not a required equation.
Therefore, the required equation is [tex]y=(x-2)^2[/tex]
The correct answer is an option (C)

A cylinder and a cone have the same height and radius. The height of each is 5 centimeters, and the radius is 2 centimeters. Calculate the volume of the cylinder and the cone (rounded to the nearest tenth). Use 3.14 as an approximation for n. PLS HELP 15 POINTS
Answer:
Step-by-step explanation:
volume of cylinder = πr²h = 3.14·2²·5 = 62.8 cm³
volume of cone = ⅓πr²h = ⅓·62.8 ≅ 20.9 cm³
The volume of the cone is 10.5 cm³. The volume of the cylinder is 31.4 cm³
What is the volume of the cylinder and the cone?
Volume of a cone = 1/3(nr^2h)
n = 22/7
r = radius
h = height
1/3 x 3.14 x 5 x 2 = 10.5 cm³
Volume of the cylinder = nr^2h
3.14 x 5 x 2 = 31.4 cm
