If the ratio of areas of two similar triangles is 9 : 4, then the ratio of its corresponding sides is .
(a) 9 : 4 (b) 4 : 9 (c) 3 : 2 (d) 81 : 16
Answer:
The answer is c
Step-by-step explanation:
If the area of the two triangles are similar, then Area of ∆ 1 : Area of ∆ 2 =
(Side of ∆ 1)² : (Side of ∆ 2)²
____________________________
Since the area of each triangle is equal to the corresponding side squared.
Area of ∆ = (Side of ∆)² →
√(Area of ∆) = Side of ∆ →
Side of ∆ = √(Area of ∆).
Therefore:
9 : 4 → √9 : √4 = 3 : 2

Answer:
It's answer is A. 557 square feet
Step-by-step explanation:
Area of semi circle
= 1/2 * π * r²
= 1/2 * 3.14 * 10²
= 157 square feet
Area of square
= 20²
= 400 square feet
Now
Total area
= 400 + 157
= 557 square feet.

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
Please help if not I with find you
Answer:
7,7,15
Step-by-step explanation:
Because the summation of two sides should be greater than the other one

Half of the animals are cats. If they take in 5 cats, then the total number of animals is 2×5 = 10.
If they take in 8 animals, the number of cats is ½ of 8 = 4.
If they take in 6 cats, then the total number of animals is 2×6 = 12.
If they take in 16 animals, the number of cats is ½ of 16 = 8.

1. Alice invests $1000 at 2% interest compounded monthly over a 5 year period. Assuming no other money is deposited or withdrawn, what is the total amount of money in her account after 5 years? (Round to the nearest cent)
Answer:
$1,105.08.
Step-by-step explanation:
Given that Alice invests $ 1000 at 2% interest compounded monthly over a 5 year period, assuming no other money is deposited or withdrawn, to determine what is the total amount of money in her account after 5 years, the following calculation must be performed:
X = 1,000 (1 + 0.02 / 12) ^ 5x12
X = 1,105.08
Thus, the amount of money in her account after 5 years would be $ 1,105.08.

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]

Step-by-step explanation:
The true square root of 51 to three decimal places is 7.141.
x < 7.141 < y.
If you insert the numbers above, you get a true inequality of
7.14 < 7.141 < 7.15.
Therefore, 7.14 and 7.15 will be your answer.

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)

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
