Step-by-step explanation:
diameterfor first minute :
Circumference = 25.12
2πr = 25.12
22/7 × r = 25.12/2
r = 12.56 × 7 /22
r = 87.92/22
r = 3.99 mm ( approx. )
diameter = 2r = 2 × 3.99 = 7.98 mm
diameter for second minute =
circumference = 75.63
2πr = 75.63
πr = 75.63/2
r = 37.815 × 7/22
r = 264.705/22
r = 12.032 mm
diameter = 2r = 24.064 mm
COMPARISON : 24.064/7.98

∠1 and ∠4 are corresponding angles has the same shape and size. ∠1 and ∠3 are diagonal from each other and ∠15 and ∠9 make a straight line.
What are parallel lines?Parallel lines represent coplanar endless straight lines in geometry that never intersect. Within a single three-dimensional space, parallel planes are any planes that never cross. Curves with a predetermined minimum distance between them and no contact or intersection are said to be parallel.
Euclid's parallel postulate deals with parallel lines. Euclidean geometry is indeed a particular example of this sort of geometry, and parallelism is essentially a feature of affine geometries.

Michiko claims that to solve the system of linear equations 15x + 8y = 1 and 21x + 4y = -13, instead of multiplying the second equation by –2 and then adding the equations, she could multiply the second equation by 2 and then subtract the second equation from the first equation. Which statement is correct?
A: Michiko is right for this system of linear equations, but her method will not work for other systems of linear equations.
B: Michiko is right for this system of linear equations, and her method will also work for other systems of linear equations.
C: Michiko is wrong because her method will give the opposite of the correct value for x for any system of linear equations.

Michiko is right for this system of linear equations, but her method will not work for other systems of linear equations, option A is correct.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
To solve the system of linear equations 15x + 8y = 1 and 21x + 4y = -13, Michiko suggests multiplying the second equation by 2 and then subtracting the second equation from the first equation.
Multiplying the second equation by 2 gives:
42x + 8y = -26
Now, subtracting the second equation from the first equation gives:
15x + 8y - (42x + 8y) = 1 - (-26)
Simplifying this equation gives:
-27x = 27
Divide both sides by 27
x=-1
we can substitute x = -1 into either of the original equations.
Using the first equation, we get:
15(-1) + 8y = 1
Simplifying this equation gives:
8y = 16
Dividing both sides by 8 gives:
y = 2
Hence, Michiko is right for this system of linear equations, but her method will not work for other systems of linear equations, option A is correct.

If a square has an area of 100ft², what is the length of one of the sides.
Answers
Answer:
The length of one side is 10 feet
Step-by-step explanation:
This is because the area of a square can be found through the formula side x side or [tex]side^{2}[/tex]. You can find the length of one side by finding the square root of the area. You would get both a positive and negative value for the square root but you want a positive value because a length cannot be negative.

Answer:
12,000, 900, 210, 18 4376x3=13128
Step-by-step explanation:
In the 1st box, you put the product of 4,000 x 3 = 12,000
In the 2nd, you put the product of 300 x 3 = 900
In the 3rd, you put the product of 70 x 3 = 210
In the 4th, you put the product of 6 x 3 = 18
Then you add your answers
12,000 + 900 + 210 + 18 = 13,128
The required partial product of 4376 × 3 is 13128.
What is the partial product?In mathematics, partial products are defined as multiplying each digit of one integer by each digit of another number while keeping each digit's place value.
Here,
4376 × 3 = [4000 + 300 + 70 + 6] × 3
Simplifying using the distribution of 3,
= 4000 × 3 + 300 × 3 + 70 × 3 + 6 × 3
= 12000 + 900 + 210 + 18
= 13128
Thus, the required partial product of 4376 × 3 is 13128.

Find an equivalent expression for -3(2x+5)-(x-1)
Answers
Answer:
-7x - 14
Step-by-step explanation:
By simplifying the expression:
-3(2x+5) - (x - 1)
-6x-15 -x + 1
-7x - 14
Answer:
-7x - 14
Step-by-step explanation:
You can use the distributive property to find an equivalent expression.
Distribute -3 to 2x + 5.
(-3 × 2x) + (-3 × 5) = -6x + (-15) = -6x - 15
Distribute -1 to x - 1. (It is -1 because there is always a 1 in front of things like x = 1x and (x + 1) = 1(x + 1). 1 times anything equals the number it is multiplied by. There is a - sign in front of the parenthesis, which makes the invisible 1 a -1.)
(-1 × x) + (-1 × -1) = -x + 1
You can simplify the expression.
(-6x - 15) + (-x + 1) = -7x - 15 + 1 = -7x - 14

An average adult giraffe is 18 feet tall. A newborn giraffe is about 6 feet tall/ Kayla is building a model of a mother giraffe and her newborn. She wants the model to be no more than 17 inches high.
Answers
Answer:
Mother = 17 inches and then Newborn = 5 (2/3) or 5.66666666667 inches
Step-by-step explanation:
I was sort of guessing based on your question what you were looking for. How I solved this is we know that since the average adult giraffe is 18 feet tall and the average newborn giraffe is 6 feet tall, then the adult giraffe is about 3 times as tall as the average newborn giraffe so the ratio is 3:1 adult: newborn. So with the mother at 17 inches, then since the newborn giraffe is, on average, 3 times smaller than the mother, it is therefore 17/3 = 5.666667 or 5 and 2/3s.
