The ratio of boys to girls at the Milwood School is 4 to 5. If there are a total of 27
children at the school, how inany boys attend the Milwood School?
Answer: 12 boys attend Millwood School.
Step-by-step explanation:
Yeah. It just makes sense. I am bad at explaining. Sorry!
The ratio shows how many times one value is contained in another value.
The ratio of boys to girls at the Milwood School is 4 to 5.
The number of girls that attended the Milwood school is 15.
The number of boys that attended the Milwood school is 12.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
The ratio of boys to girls at the Milwood School is 4 to 5.
Total number of children = 27
Let the number of boys = 4x
Let the number of girls = 5x
Now,
4x + 5x = 27
9x = 27
x = 3
Now,
The number of boys = 4x = 4 x 3 = 12
The number of girls = 5x = 5 x 3 = 15
Thus,
The number of boys that attended the Milwood school is 12.

If the area of a rectangle is expressed as x4 - 9y2, then the product of the length and the width of the rectangle could be expressed as 1) (x - 3)(x + 3y) 2) (r? – 3y)(x2 + 3y) 3) (r? – 3y)(r? - 3y) 4) (x +y)(x-9y)
Answer:
Step-by-step explanation:
the area of the rectangle is a difference of two squares
so it can be expressed
(x^2-3y)(x^2+3y)
Answer:
(x^2-3y)(x^2+3y) if you multiply them all together you get the final answer of x^4-9y^2

Step-by-step explanation:
Find the sum of the first eight terms of a geometric series is the fourth term of 25 in the constant ratio is 3/5 . Answer your answer as a decimal rounded to two places
25 = a1(1- (0.6)⁴)/(1-0.6)
25 = a1 (1- 0.13)/(0.4)
10 = a1(0.87)
a1 = 11.49
S8 = 11.49(1- (0.6)^8)/(1-0.6)
= 11.49(1-0.017)(1-0.6)
= 11.49(0.983)/0.4
= 28.24
The sum of the first eight terms of the given geometric series is; 28.24
How to find the sum of a geometric series?
We are told that the sum of the first four terms of the geometric series is 25. Thus, formula for sum of n terms of a geometric series is;
Sₙ = a(1 - rⁿ)/(1 - r)
where;
a is first term
r is common ratio
Thus;
25 = a(1 - (0.6)⁴)/(1 - 0.6)
25 = a(1 - 0.13)/(0.4)
10 = 0.87a
a = 11.49
Thus, sum of the first 8 terms of the series is;
S₈ = 11.49(1 - 0.6⁸)/(1 - 0.6)
S₈ = 11.49(1 - 0.017)(1 - 0.6)
S₈ = 28.24

if that is = a, find the value of a + 1 over a
[tex]3 - \sqrt{5} [/tex]
Answer:
7+√5/4
Step-by-step explanation:
if that is = a, find the value of a + 1 over a
Given that a = 3 - √5
a+1/1 = (3-√5)+1/3 - √5
4-√5/3 - √5
Rationalize
4-√5/3 - √5 * 3+√5/3 + √5
= 12 +4√5-3√5-√25/9-5
= 12+√5-5/4
= 7+√5/4
Hence the requred answer is 7+√5/4

Answer:
13 / 25 were boys
14 / 25 were girls
Step-by-step explanation:
Of the girls 10 said no and 4 said yes
10 + 4 = 14 so she asked a total of 14 girls
Of the boys 8 said yes and 5 said no
8 + 5 = 13 so she asked a total of 13 boys
she asked 14 girls and 13 boys
14 + 13 = 25 so she asked a total of 25 people
Out of the 25 people she asked 13 of them were boys
So 13 out of 25 people we boys
or 13 / 25
which means 14 out of 25 were girls
or 14 / 25

Find the volume of the composite solid. Round your
anwser to the nearest hundredth.
Answer:
226.19 [tex]cm^{3}[/tex]
Step-by-step explanation:
Vol. of cone = Bh/3 where B is the area of the base(circle) and h is the height of the cone.
r = 3 h = 3
V = [tex]\frac{\pi *3^{2}*3 }{3}[/tex] = 9π
Vol. of the cylinder = Bh where B is the base(circle) and h is the height of the cylinder.
r = 3 h = 10 - 3 = 7
V = [tex]\pi *3^{2} * 7[/tex] = 63π
Total volume = 9π + 63π = 72π = 72(3.1416....) = 226.19
Volume is a three-dimensional scalar quantity. The volume of the composite figure will be 226.194cm³.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
The volume of the composite solid is the sum of the slanted cylinder and the cone. Therefore, the volume will be,
Volume = Volume of cone + Volume of slant cylinder
= [(1/3)πr²h] + [πr²H]
= [(1/3)×π×(3)²×3] + [π×(3)²×7]
= 28.274 cm³ + 197.920 cm³
= 226.194 cm³
Hence, the volume of the composite figure will be 226.194cm³.

Cindy's square-shaped garden has side lengths of x ft. She will plant 5 tulip bulbs per square foot. Write a function g to model the number of bulbs she should plant. How many bulbs will she plant if the garden has a side length of 8 feet? for this problem what is the function we need to write g(x)=?
Answer:
The total number of bulbs are "320 bulbs".
Step-by-step explanation:
According to the question,
The square garden's side length,
x = 8 feet
Number of tulip bulbs she plant,
= 5
Now,
As per the question, the area of square will be:
⇒ [tex]A=x^2[/tex]
[tex]=(8)^2[/tex]
[tex]=64[/tex]
hence,
The total number of bulbs will be:
⇒ [tex]n=A\times 5[/tex]
[tex]=64\times 5[/tex]
[tex]=320 \ bulbs[/tex]
Thus the above is the correct solution.
