a shop sells 3 types of boots ( football , rugby and hiking) sales are usually in the ratio of 6 : 2 : 3 last month , 24 pairs of boots were sold . How many boots altogether last moth

Answers

Answer:

44

Step-by-step explanation:

First, let's sum up the ratio.

Sum the ratios = 6 + 2 + 3 = 11

We can make y the total number of boots sold together last month

If 24 pairs of boots were sold, then the equation would be

6/11 × y = 24

Cross multiply

6 × y = 24 × 11

6y = 264

y = 44

Therefore, total number of boots sold altogether last month were 44

The legs of a right triangle are 4 units and 7 units. What is the length of the hypotenuse?

square root 33 units
square root 65 units
33 units
65 units

Answers

By applying Pythagoras theorem,we get

(hypotenuse)^2=(base)^2+(perpendicular)^2

=>(h)^2=(7)^2+(4)^2

=>(h)^2=49+16

=>(h)^2=65

=>h=√65

Therefore, option B is correct,i.e.,√65

Answer:

Square root of 65 units

Step-by-step explanation:

The area of the region under the curve of a function f(x) = ax + b on the interval [0, 4] is 16 square units.


(a, b) ≠

Answers

Answer:

[tex](a,b) \ne (7,-9)[/tex]

Step-by-step explanation:

Given

[tex]f(x) = ax + b[/tex]

[tex]Interval = [0,4][/tex]

[tex]Area = 16[/tex]

Required

[tex]a, b \ne[/tex]

The area is calculated as:

[tex]Area = \int\limits^a_b {f(x)} \, dx[/tex]

So, we have:

[tex]Area = \int\limits^4_0 {(ax + b)} \, dx[/tex]

Integrate

[tex]Area = (\frac{ax^2}{2} + bx)|\limits^4_0[/tex]

Expand

[tex]Area = [(\frac{a*4^2}{2} + b*4)] - [(\frac{a*0^2}{2} + b*0)][/tex]

[tex]Area = [(\frac{a*4^2}{2} + b*4)][/tex]

[tex]Area = 8a+ 4b[/tex]

This gives:

[tex]8a + 4b = 16[/tex]

Divide through by 4

[tex]2a + b = 4[/tex]

From the list of options, the possible values of a and b are:

[tex](a,b) = (-2,8) \to 2 * -2 + 8 = 4[/tex]  

[tex](a,b) = (1,2) \to 2 * 1 + 2 = 4[/tex]

[tex](a,b) = (3,-2) \to 2 * 3 -2 = 4[/tex]

[tex](a,b) = (5,-6) \to 2 * 5 -6 = 4[/tex]

The odd one is:

[tex](a,b) = (7,-9) \to 2 * 7 -9 = 5[/tex]

Hence:

[tex](a,b) \ne (7,-9)[/tex]

help me with this math question please I'm giving away brainliests ​

Answers

Answer:

Step-by-step explanation:

Given function is,

[tex]f(x)=\frac{2x^2+6x}{-4x^2+8x}[/tex]

       [tex]=\frac{2x(x+3)}{-4x(x-2)}[/tex]

This function is not defined at "x(x - 2) = 0"

Therefore, for the values of x = 0 and 2, given function is not defined.

Vertical asymptote → x = 2 [Denominator = 0]

For Horizontal asymptote → [tex][\frac{2x^2}{-4x^2} =-\frac{1}{2}][/tex]

Therefore, horizontal asymptote → y = [tex]-\frac{1}{2}[/tex]

x-intercept,

For f(x) = 0,

Numerator of the function = 0

2x² + 6x = 0

2x(x + 3) = 0

x = -3

Therefore, x - intercept → (-3, 0)

For y-intercept,

x = 0

f(0) = 0

Therefore, graph has no y-intercept.

For holes on the graph,

Since, function is not defined at x = 0,

f(x) = [tex]\frac{(x+3)}{-2(x-2)}[/tex]

f(0) = [tex]\frac{(0+3)}{-2(0-2)}[/tex]

     = [tex]\frac{3}{4}[/tex]

Therefore, hole on the graph → [tex](0, \frac{3}{4})[/tex]

A. value claim B. cause claim C. fact claim D. policy claimHere is the debate essay - Supporters of school uniforms assert that when students wear uniforms their attendance improves. They claim that students who wear uniforms have more school spirit which encourages students to attend more often. In Irving, Texas, schools have been able to improve average daily attendance through a strict uniform policy. Though students do not wear official uniforms, they wear white shirts, khaki pants, and leather shoes that must meet certain uniform requirements. However, in nearby Euless, Texas, no uniforms are required, and yet students have higher average daily attendance rates than at the charter school in Irving. This seems to demonstrate that higher attendance rates have little to do with uniforms. A school in Polk County, Florida, has the most restrictive uniform policy in the nation. It was enacted in 1999, and since then, the school has found that its average daily attendance has fallen dramatically. In 2000, the school broke a national scholastic absentee record for the same school year. These results show that uniforms have no effect on attendance. In fact, it shows evidence to the contrary; strict uniform policies have a negative effect on attendance. Moreover, the enforcement of uniform policies consumes resources in terms of time and manpower. Teachers and administrators must constantly be on the alert for students who do not maintain the policy. Also, students who come into violation of the policy must be disciplined, which causes stress and additional work that might take up time they could otherwise spend studying. One of the most extreme cases of uniform policy violations occurred at the school in Polk County in 1999. An assistant principal reprimanded a student for wearing pants with a 4% spandex weave because spandex pants were not permitted by uniform policy. Events like this are common. In Polk County, parents and teachers once worked together for the best of their students. Now, there is a rift between the two groups over the uniform issue.
