Answer: 14:3

Step-by-step explanation:

Given

Ratio between students(s) to female(f) adults is 7:6

while ratio between female(f) to male(m) is 4:1

So, we can write

[tex]\Rightarrow \dfrac{s}{f}=\dfrac{7}{6}\quad \ldots(i)[/tex]

Also, we can write

[tex]\Rightarrow \dfrac{f}{m}=\dfrac{4}{1}\quad \ldots(ii)[/tex]

Multiply both equations

[tex]\Rightarrow \dfrac{s}{f}\times \dfrac{f}{m}=\dfrac{7}{6}\times \dfrac{4}{1}\\\\ \Rightarrow \dfrac{s}{m}=\dfrac{14}{3}[/tex]

So, the ratio of the students to male adults is 14:3 .

Answer:

Add 3 to both sides of the equation

Solution:

The first step is to basically realize that all it's asking you to do is to find a way to make the expression on the left ([tex]x^2 - 8x + 13[/tex]) into an expression that is a perfect square. So what number should you add to both sides such that [tex]x^2 - 8x + (13 + j)[/tex] can be factored into [tex](x-p)^2[/tex] ? Well, we can approach it like this:

Since [tex](x-p)^2[/tex] can be turned into [tex]x^2 -2px + p^2[/tex], and our original form was [tex]x^2 - 8x + (13 + j)[/tex], we quickly realize that [tex]-2px = -8x[/tex]. From there, we can easily tell that [tex]p = 4[/tex]

Plug this into our last value [tex]p^2[/tex] to get 16. Therefore, if we compare this with our original equation again [tex]x^2 - 8x + (13 + j)[/tex], we notice that 13 + j = 16.

Thus, j = 3 for the last answer.

Add 3 to both sides of the equation.

Note: With more practice, you will quickly gain enough intuition to notice that [tex]x^2 - 8x + 13[/tex] is very close to [tex]x^2 - 8x + 16[/tex] which can be factored into [tex](x-4)^2[/tex]. But for now, the solution above will suffice. I hope this helps :))

Volume = 1526.04 cubic units

Step-by-step explanation:

Formula for volume of a cone:

V = πr²h/3

If we use 3.14 for pi, we get 1526.04:

V = 3.14(9)^2(18)/3

V = 1526.04

Answer:

a) y(x) = (x + 2)^2 -2

b) minimum

c) (-2, -2)

Answer:

see explanation

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

• If a > 0 then vertex is minimum

• If a < 0 then vertex is maximum

Given

y = x² + 4x + 2

(a)

To complete the square

add/ subtract ( half the coefficient of the x- term)² to x² + 4x

y = x² + 2(2)x + 4 - 4 + 2

y = (x + 2)² - 2

(b)

Since a = 1 > 0 then vertex is minimum

(c)

(h, k ) = (- 2, - 2 ) ← coordinates of vertex

Answer:

B. 64 cubic meters

Step-by-step explanation:

The first rectangle has the dimensions 7 x 2 x 4. 2 x 4 is 8, and 8 x 7 is 56. The square has the dimensions 2 x 2 x 2, which is 8. 56 + 8 is 64, so the answer is 64.

6.  175/125=x/100

Cross products  equal 125x=17500

Solve for x and you get 140%

7.  20% of 720 is 144.  You need to find 120% so add the full 720 (100%) to the 144 and you get 864 (120%)

Step-by-step explanation:

Answer:

6. 140%    7. 864

Step-by-step explanation:

Step for #1:

1.) 175 ÷ 125 = 1.4

2.) 1.0=100   0.4=40

3.) 1.4 = 140%

Answer; 140%

Step for #2:

1.) 120% × 720 = ?

2.) 120 x 720 = 86,400

3.) 86,400 ÷ 100 = 864

Answer; 864

Answer:

20 millimeters.

Step-by-step explanation:

To find the radius of a circle with circumference, you must divide the circumference by pi (3.14).

After dividing the circumference by pi, you now have the diameter of the circle.

Secondly, to get the radius, divide the quotient (the diameter) by 2.

The quotient is the radius of the circle.

----------------------------------------------------------------------------------------------------------------

Now, I will repeat these steps using the circumference of 125.6 millimeters.

125.6 ÷ 3.14 = 40.

40 ÷ 2 = 20.

Therefore, 20 millimeters is the radius of this circle.

The circle's radius is mathematically given as

r=20

Question Parameter(s):

The circumference of a circle is 125.6 millimeters.

Generally, the equation for the circumference  is mathematically given as

C=2\pi r

Therefore

C=2 *3.14*r

125.6=2 *3.14*r

r=20

In conclusion, The raduis

r=20

Step-by-step explanation:

Remember the rule: the sum of the two shortest sides must be bigger than the longest side. From there, the answers should be obvious. Just add up the smallest sides for each triplet of lengths and see if that is bigger than the largest side.
