Answer:

25.15 in

Step-by-step explanation:

let's say that x = wide

so x+5.89=length

the perimeter is = 2(width +length)

P=2(x+x+5.89)

108.39=2(2x+5.89)

2x+5.89=54.195

2x=48.305

x=24.1525 in

which is 24.15 in

Answer:

C

1/7 is greater than 1/8 so 1/7 must go after it. but negative is always less then positive so the correct order is

-1/8, -1/7, 1/8, 1/7

The numbers arranged in increasing order is

-1/8, -1/7, 1/8, 1/7

There are 4 values given:

1/7, 1/8, - 1/7, - 1/8

Negative figures are generally lesser than positive figures

1/7 is greater than 1/8

In negative values, the greater number becomes the smaller number

Therefore,

-1/8 is the the smaller number

Arrangements in increasing order =

-1/8, -1/7, 1/8, 1/7

Answer:

[tex]\sqrt{20}[/tex]

Step-by-step explanation:

To find the Apothem of a shape, we need to find how long the distance is from a vertex to the center of the shape.

We can see that they've already showed us how to do it: We need to find the length of the hypotenuse of the red triangle.

To do this, we can use the Pythagorean Theorem, which states that [tex]a^2 + b^2 = c^2[/tex].

We know that a is going to be half of 4, which is 2. We also know that b is going to be 4, so we can substitute inside the equation.

[tex]2^2 + 4^2 = c^2\\\\4 + 16 = c^2\\\\20=c^2\\\\c=\sqrt{20}[/tex]

Answer:

SU = 36

Step-by-step explanation:

T is the mid point so the distance of ST and TU is the same. Since ST and TU are the same, 7x + 4 = 10x - 2.

Solve for x

7x + 4 = 10x - 2

7x - 10x = - 2 - 4

-3x = -6

x = 2.

Find SU

SU = ST + TU

= (7x + 4) + (10x - 2)

substitute the value for x into the equation (x=2)

[7(2) + 4] + [10(2) - 2] = 36

Answer:

- 4

Step-by-step explanation:

The conjugate of - 2 + i is - 2 - i, thus

- 2 + i + (- 2) - i

= - 2 + i - 2 - i ← collect like terms

= - 4 ← in the form a + bi with b = 0

The sum of -2 + i and its complex conjugate is:

w = -4 + 0i

The complex conjugate of a number z = a + bi is:

z' = a - bi.

Then the complex conjugate of -2 + i is -2 - i.

The sum will give:

w = -2 + i + (-2 - i) = -4 + 0

Writing it in the wanted form we get:

w = -4 + 0i

Step-by-step explanation:

Hey, there!

As it is a Right angled triangle, taking reference angle as angle B.

hypotenuse (h)= AB

perpendicular (p)= 12

base (b)= 24.

Now, let's look which ratio can be used here as p and b are given. Let's use tan ratio here.( as tan = p/b)

[tex] \tan(theta) = \frac{p}{b} [/tex]

[tex]tan(theta) = \frac{12}{24} [/tex]

[tex] \tan(theta) = \frac{1}{2} [/tex]

or, tan theta = (0.5)

Shifting tan to right side making it inverse.

or, theta = tan inverse (0.5)

Therefore, theta = 26.56° or 27° { by rounding off 26.56° we get 27°}.

Answer:

Hey mate!

Using Unitary Method, we get :

2 people -> 5 hours

1 person -> 5/2 = 2.5 hours

3 people -> 2.5 hours * 3 peoples

-> 7.5 hours

-> 7.5 * 60 = 450 mins.

Answer:

3 people can plow a field in 450 minutes.

Step-by-step explanation:

This is a rate/ratio problem, so we have to make sure it's fully simplified.

First, you already know the ratio is 2 people can plow a field in 5 hours, so 2:5.

But that's not the unit rate.

To find the unit rate, you find how much an individual by itself can do their work, and divide numerator by denominator.

In this case, you do 5/2: which is 2.5.

It take's 2.5 hours for one person. Now you multiply by 3 people to get the ratio; since you already found the rate.

2.5x3 is 7.5, and that's in hours. 1 hour is 60 minutes, to find 7 hours, you do 60x7 and get 420 minutes. You add 30 minutes from the remaining half hour.

that results in 450 minutes.

3 people can plow a field in 450 minutes.

Answer:

The answer is -2 5/14 if you're trying to solve for m

Step-by-step explanation:

first you get rid of the fractions by mutiplying both sides by 4.

4(4m-3/4)=(-9+4m/8)4

16m-3=-36+2m      then you put the varible terms on one side and the numbers on one side

14m=-33

then divide -33 by 14

which will give you the fraction -2 5/14 unless you want decimal form which would be around -2.36

Answer:

14 boys paid for the full year fee and 4 boys paid for the partial year fee

Step-by-step explanation:

Create a system of equations, where x is the number that paid for the $24 fee and y is the number that paid for the $16 fee:

24x + 16y = 400

x = y + 10

Solve by substitution by plugging in y + 10 as x:

24x + 16y = 400

24(y + 10) + 16y = 400

Solve for y:

24y + 240 + 16y = 400

40y + 240 = 400

40y = 160

y = 4

Then, plug in 4 as y to find x:

x = y + 10

x = 4 + 10

x = 14

So, 14 boys paid for the full year fee and 4 boys paid for the partial year fee.

Answer:

[tex]y=\frac{48}{x}[/tex]

Step-by-step explanation:

When x = 3, y = 16

When x = 6, y = 8

We need to model the inverse variation.

Inverse Variation : When one value increase another value decrease. But product of both always constant.  

[tex]xy=k[/tex]

when x=3, y=16

k=48

When x=6, y=8

k=48

Model of the inverse variation:

[tex]y=\frac{48}{x}[/tex]

Hence, The model of inverse variation is

[tex]y=\frac{48}{x}[/tex]

Answer:

The inverse variation equation can be used to model this function is:

[tex]y=\frac{48}{x}[/tex]

Step-by-step explanation:

An inverse relationship between two variables implies that if the value of one variable increases the value of the other variable will decreases and vice-versa.

The inverse function describing the relationship between x and y is as follows:

[tex]y=\frac{a}{x}[/tex]

Here, a is a constant.

It is provided that when the value of x is 3 the value of y is 16.

Compute the value of a as follows:

[tex]y=\frac{a}{x}[/tex]

[tex]16=\frac{a}{3}\\\\[/tex]

[tex]a=48[/tex]

It is also provided that when the value of x is 6 the value of y is 8.

Compute the value of a as follows:

[tex]y=\frac{a}{x}[/tex]

[tex]8=\frac{a}{6}\\\\[/tex]

[tex]a=48[/tex]

The value of a is 48.

Then the inverse variation equation can be used to model this function is:

[tex]y=\frac{48}{x}[/tex]

Answer:

-5

Step-by-step explanation:

Coordinate of A = -7

Coordinate if B = 5

Distance of AB = |-7 - 5| = |-12| = 12

We are asked to find the coordinate of the point that would be ⅙ from the A to B, which is ⅙ of AB.

Let's find what ⅙ of AB is.

AB = 12

Therefore, ⅙ of AB = ⅙*12 = 2.

From point A (-7), we move 2 points towards B which will give us ⅙ from A to B.

The coordinate = -7 + 2 = -5

-5 is the coordinate of the point with a fraction distance of ⅙ from A to B.

Answer:

Step-by-step explanation:

Using the method of completing the square.

Given

f(x) = x² + 4x - 6

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

f(x) = x² + 2(2)x 6 + 4 - 4 - 6

      = (x + 2)² - 10

with m = 2 and n = - 10

To solve the equation let f(x) = 0 , that is

(x + 2)² - 10 = 0 ( add 10 to both sides )

(x + 2)² = 10 ( take the square root of both sides )

x + 2 = ± [tex]\sqrt{10}[/tex] ( subtract 2 from both sides )

x = - 2 ± [tex]\sqrt{10}[/tex]

The positive solution is

x = - 2+ [tex]\sqrt{10}[/tex] ≈ 1.16 ( to 2 dec. places )
