Answer: 36
Step-by-step explanation:
Given
The ratio of Mary's to Helen's necklaces is 25:9
Mary has 100 necklaces
Suppose Helen has x necklaces
Therefore the ratio can be written like
[tex]\Rightarrow \dfrac{25}{9}=\dfrac{100}{x}\\\\\Rightarrow x=\dfrac{100}{25}\times 9\\\\\Rightarrow x=4\times 9\\\Rightarrow x=36[/tex]
So, Helen has 36 necklaces

I need help with finding the volume of this rectangle and also what formula you used so I can understand it. Thanks
Answer:
Step-by-step explanation:
Equation
The volume formula is
V = L * W * H
Givens
From the diagram
L = 6 mi
W = 2 mi
H = 5 mi
Solution
V = 6 * 5 * 2
V = 60 cubic miles

If you spin the spinner once, determine the probability and the likelihood of spinning with colors red, orange, blue or green, red blue orange or green, not red
Answer:
Step-by-step explanation: There are 12 colours on a spinner,
Probability of red,orange, blue or green = 1/12×4 =4/12
=1/3
Probability of red,blue, orange or green= 1/12×4=1/3
Probability of not red= 1-1/12
=11/12

What is the equation of the line perpendicular to y = -x+6 that passes through the
2
point (4, 1)?
Answer:
[tex]y=x-3[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Perpendicular lines always have slopes that are negative reciprocals (ex. 3 and -1/3, 1/2 and -2, etc.)1) Determine the slope (m)
[tex]y = -x+6[/tex]
Looking at the given line, we can identify clearly that -1 is in the place of m, making it the slope of the line. Because perpendicular lines have slopes that are negative reciprocals of each other, we know that the slope of the line we're solving for is 1. Plug this into [tex]y=mx+b[/tex]:
[tex]y=x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=x+b[/tex]
Plug in the given point (4,1)
[tex]1=4+b[/tex]
Subtract 4 from both sides
[tex]1-4=4+b-4\\-3=b[/tex]
Therefore, the y-intercept is -3. Plug this back into [tex]y=x+b[/tex]:
[tex]y=x-3[/tex]

Which expression is equivalent to 15 + 35
Answer:
5(3+7)are equal to15+35
Step-by-step explanation:
5(3+7) five multiply the bracket
15+35
it help you
Answer:
C5(3+7)
Step-by-step explanation:
So, lets ingore the answers, and jsut try to break down 15+35
What can we take from both 15 and 35?
Well, 5 is the only one I can see in this.
So lets take 5 from this:
5(3 + 7)
We got 3 since 5x3 is 15, and we got 7 since 5x7 is 35.
So lets look at our answers and see if 5(3 + 7) is one of them
Well, looking at C, that is exactly 5(3 +7)
So c is our answer.
Hope this helps!
Jack bought a motorbike the original price was $1800 but he got a discount of 15% what was the discounted price of the bike
Answer:
$1530
Step-by-step explanation:
Hi there!
What we know
Original price was $1800There was a discount of 15%If this motorbike was on sale for 15% off, then we know that its discounted price is 85% of the original price (100-15=85)
Then, to find the discounted price, we multiply 1800 by 85%:
1800 × 85%
Change 85% into a decimal
= 1800 × 0.85
= 1530
Therefore the discounted price of the motorbike was $1530.
I hope this helps!

Note: Consider we need to find the factor form of the given expression by taking out the GCF.
Given:
The expression is:
[tex]-42k^3+24k^4+12k^5[/tex]
To find:
The factor form of the given expression.
Solution:
We have,
[tex]-42k^3+24k^4+12k^5[/tex]
It can be written as:
[tex]=6k^3(-7)+6k^3(4k)+6k^3(2k^2)[/tex]
Taking out the greatest common factor (GCF), we get
[tex]=6k^3(-7+4k+2k^2)[/tex]
Therefore, the factor form of the given expression is [tex]6k^3(-7+4k+2k^2)[/tex].

A triangle has an area of 40 cm². The base and height are scaled by a factor of 4.
The area of the resulting triangle is ___ square cm.
Answer:

Step-by-step explanation:
Here is a triangular prism. 4 cm 10 cm 5cm 5cm 6cm
A. What is the volume of the prism, in cubic centimeters?
B. What is the surface area of the prism, in square centimeters?
Answer:
(A) 120 cm³
(B) 184 cm²
Step-by-step explanation:
(A)
Assuming the diagram attached is thesame as the one needed to complete the question,
Applying
V = A'×L................... Equation 1
Where V = volume of the prism, A' = Area of the triangular base, L = Length of the prism.
But,
A' = 1/2bh............. Equation 2
Where b = base of the triangle, h = height of the triangle.
Substitute equation 2 into equation 1
V = 1/2bh(L)............... Equation 3
From the question,
Given: b = 6 cm, h = 4 cm, L = 10 cm
Substitute these values into equation 3
V = 1/2(6×4×10)
V = 120 cm³
(B)
Surface area of the prism(A) = bh+L(a+b+c).............. Equation 4
Given: b = 6 cm, b = 5 cm, c = 5 cm, L = 10 cm, h = 4 cm
Substitute these values into equation 4
A = (6×4)+10(5+5+6)
A = 24+160
A = 184 cm²
