A coin bank for donations for the protection of the reef contained Php 1,570. There were twice as many Php 5-coins as
Php 10-coins and 14 less Php 1-coins as Php 5-coins. How many of each kind were there?
Answer:
There are 144 Php 5-coins, 72 Php 10-coins and 130 Php-1 coins
Step-by-step explanation:
The amount of the coins in the coin bank = Php 1,570
The number of Php 5-coins = 2 × The number of Php 10-coins
The number of Php 5 coins = The number of Php 1-coins + 14
Let 'x' represent the number of Php-5 coins, let 'y' represent the number of Php 10-coins, and let 'z' represent the number of Php 1-coins, we get;
x = 2 × y...(1)
x = z + 14...(2)
5·x + 10·y + z = 1,570...(3)
From equation (1) equation (2), and equation three, we have;
y = x/2
z = x - 14
5·x + 10·x/2 + x - 14 = 1,570
11·x - 14 = 1,570
x = (1,570 + 14)/11 = 144
The number of Php 5-coins, x = 144
y = x/2
∴ y = 144/2 = 72
The number of Php 10-coins, y = 72
z = x - 14
∴ z = 144 - 14 = 130
The number of Php 1-coins, z = 130
Y=5x-9
-2x-3y=-7

WILL GIVE 100 POINTS TO WHOEVER ANSWER THIS CORRECTLY. In the similarity transformation of abc to def, abc was dilated by a scale factor of ?, reflected across the , and moved through the translation
Answer:
Dialated by a scale factor of two, reflected across the x axis, and transformed three units left
Step-by-step explanation:
The triangle was dilated by a scale factor of 2
What is similarity transformation?
One or more stiff transformations (such as reflection, rotation, and translation) followed by a dilation make up a similarity transformation. An image that resembles the original figure is produced when a figure undergoes a similarity transformation.
The following steps are followed while determining the similarities:
Step 1 is to identify the triangles' pairs of corresponding sides and pairs of matching angles. Step 2 Redraft the triangles with the same orientation and space between them. Step 3 Give the triangles names and create a similarity assertion,making sure to maintain the order of corresponding vertices.Solution:
Given:
AB=2, AC=1, BC=√5
DC=4, DF=2, EF=2√5
So scale factor is 4/2 = 2/1 = 2√5/√5 = 2
hence we get tha scale factor as 2.
Therefore, In the similarity transformation of abc to def, abc was dilated by a scale of 2.

A party is held in a large tent with a perimeter between 100 m and 150 m. A robot travels along
the perimeter to serve refreshments to guests. It is
programmed in such a way that it travels 3 metres,
then turns through an angle of x degrees clockwise, travels
another 3 metres, then turns through an angle of x degrees
clockwise, and so on, until it reaches its initial
position where the staff will top up the
refreshments. Given that the robot is only able
to turn through an integer value of x, find two
possible values of x and the corresponding
perimeters of the tent.
Step-by-step explanation:
the tent can be :
1. perimeter 120 m.
40 sides polygon with 3 metres length each.
so, x = 360/40 = 9°
2. perimeter 135 m.
45 sides polygon with 3 metres length each.
so, x = 360/45= 8°
Step-by-step explanation:
the tent can be :
1. perimeter 120 m.
40 sides polygon with 3 metres length each.
so, x = 360/40 = 9°
2. perimeter 135 m.

Is the triangle a right triangle?
4 6 7
Is this a right triangle?
Answer:
No
Step-by-step explanation:
Given :-
A triangle with some side measure .The sides are 4 ,6,7.And we need to tell whether it is a right angled triangle or not . It will be a right angled triangle if it follows the Pythagoras Theorem.
Pythagoras Theorem :-
In right angle triangle the sum of squares of the two smallest sides is equal to the square of the largest side .Here the two smallest sides are 4 & 6 .
Sum of Squares of 4 and 6 :-
[tex]:\implies[/tex] 4² + 6²
[tex]:\implies[/tex] 24 + 36
[tex]:\implies[/tex] 60
Square of 7 :-
[tex]:\implies[/tex] 7²
[tex]:\implies[/tex] 49
And :-
They aren't equal. So the triangle is not a right angled triangle .Hence the triangle is not a right angle triangle.
Answer:
No, this triangle is not a right triangle.
Step-by-step explanation:
Step 1: Definition(s)/explanations
This is a right triangle, so the Pythagorean Theorem applies.The Pythagorean Theorem states that the legs of the triangle, squared, must equal the hypotenuse, squared.The legs of the triangle are the sides that make the right angle.The hypotenuse is the longest side.Formula:
[tex]pt-a^2+b^2=c^2[/tex]
[tex]legs=a,b[/tex]
[tex]hypotenuse=c[/tex]
Step 2: Solve.
Now, I just plug the numbers into the formula.
[tex]a^2+b^2=c^2[/tex]
[tex]4^2+6^2=7^2[/tex]
[tex]16+36\neq 49[/tex]
If the legs of the triangle do not equal the hypotenuse, then the triangle cannot be a right triangle.
Step 3: Conclude.
Therefore, the triangle cannot be a right triangle.

Answer:
So option 4; [tex]\frac{35}{100}[/tex] is the correct option
Step-by-step explanation:
First, we need to convert [tex]\frac{2}{10}[/tex] so it's denominator is 100. To do so, we will multiply the numerator and denominator by 10
[tex]\frac{2}{10} *\frac{10}{10} = \frac{20}{100}[/tex]
Second, we need to add the two fractions to get the current total distance walked. Remember, when adding fractions, the denominator does not change.
[tex]\frac{45}{100} + \frac{20}{100} = \frac{65}{100}[/tex]
Now that we have the total distance walked, we need to subtract that to 1 mile. [tex]1mile=\frac{1}{1} = \frac{10}{10} =\frac{100}{100}[/tex]
[tex]\frac{100}{100} -\frac{65}{100} = \frac{35}{100}[/tex]
So option 4; [tex]\frac{35}{100}[/tex] is the correct option

Factor using the x method
( please do not answer without showing work )
Answer:
[tex]5(x + 10)(10x - 3)[/tex]
Step-by-step explanation:
We are factoring
[tex]50x^{2} + 485x - 150[/tex]
So:
((2•5^2x^2) + 485x) - 150
Pull like factors :
50x^2 + 485x - 150 = 5 • (10x^2 + 97x - 30)
Factor
10x^2 + 97x - 30
Step-1: Multiply the coefficient of the first term by the constant 10 • -30 = -300
Step-2: Find two factors of -300 whose sum equals the coefficient of the middle term, which is 97.
-300 + 1 = -299
-150 + 2 = -148
-100 + 3 = -97
-75 + 4 = -71
-60 + 5 = -55
-50 + 6 = -44
-30 + 10 = -20
-25 + 12 = -13
-20 + 15 = -5
-15 + 20 = 5
-12 + 25 = 13
-10 + 30 = 20
-6 + 50 = 44
-5 + 60 = 55
-4 + 75 = 71
-3 + 100 = 97
Step-3: Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -3 and 100
10x^2 - 3x + 100x - 30
Step-4: Add up the first 2 terms, pulling out like factors:
x • (10x-3)
Add up the last 2 terms, pulling out common factors:
10 • (10x-3)
Step-5: Add up the four terms of step 4:
(x+10) • (10x-3)
Which is the desired factorization
Thus your answer is
[tex]5(x + 10)(10x - 3)[/tex]
Answer:
[tex] \displaystyle \rm 5({x}^{} + 10)( 10x - 3)[/tex]
Step-by-step explanation:
we would like to factor out the following expression:
[tex] \displaystyle {50x}^{2} + 485x - 150[/tex]
notice that, in every term there's a common factor of 5 thus factor it out:
[tex] \displaystyle 5( {10x}^{2} + 97x - 30)[/tex]
now we have to rewrite the middle term as sum or substraction of two different terms in that case 100x-3x can be considered:
[tex] \displaystyle 5( {10x}^{2} + 100 - 3x - 30)[/tex]
factor out 10x:
[tex] \displaystyle 5( 10({x}^{2} + 10)- 3x - 30)[/tex]
factor out -3:
[tex] \displaystyle \rm 5( 10x({x}^{} + 10)- 3(x + 10))[/tex]
group:
[tex] \displaystyle \rm 5({x}^{} + 10)( 10x - 3)[/tex]
and we are done!
hence,
our answer is B)
How to work out Pythagoras Theoram
The Pythagorean Theorem works only with right angle triangles. There are three sides: Side A, Side B, and the hypotenuse.
The formula for the Pythagorean Theorem is: a^2 + b^2 = c^2
To find the answer (without the exponent), you should find the square root.
Now that we have the formula, let's apply it to a triangle:
90^2 + 95^2 = c^2 =
8100 + 9025 = 17125
Square root = 130.86252328302
130.86252328302 is the exact measure of the hypotenuse.
