[tex] {( \frac{4}{25} )}^{ - \frac{1}{2} } [/tex]

Apply indices rule and Simplify

[tex] \frac{1}{ {( \frac{4}{25} )}^{ \frac{1}{2} } } = \frac{1}{ \sqrt{ \frac{4}{25} } } = \frac{1}{ \frac{2}{5} } \\ = \frac{1}{1} \div \frac{2}{5} [/tex]

[tex] = \frac{1 \times 5}{1 \times 2} \\ = \frac{5}{2} \\ = 2 \frac{1}{2} [/tex]

Answer:

area = 84 cm²

Step-by-step explanation:

the quadrilateral is made up of 2 triangles ABD and BDC

area of Δ ABD = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

A = [tex]\frac{1}{2}[/tex] × BD × AE = [tex]\frac{1}{2}[/tex] × 14 × 7 = 7 × 7 = 49 cm²

area of Δ BDC = [tex]\frac{1}{2}[/tex] × BD × CF = [tex]\frac{1}{2}[/tex] × 14 × 5 = 7 × 5 = 35 cm²

area of ABCD = 49 + 35 = 84 cm²

Answer:

x = 20

Step-by-step explanation:

these are alternate interior angles, which means they're equal.

you can use that information to make this equation:

x + 40 = 3x

subtract x from both sides

40 = 2x

divide both sides by 2

20 = x

Answer:

temperature decreased by -3.5 degrees

Step-by-step explanation:

-14 3/4 = -14.75

-18 1/4 = -18.25

-14.75 + X = -18.25

X = -3.5 or -3 2/4

The arc length of the sector is 7.065 approximately 7.1 cm. Then the correct option is D.

It is a locus of a point drawn equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The central angle of π/2 radians in a circle with a radius of 4.5 cm.

Then the arc length will be

[tex]\rm Arc \ length = \dfrac{\pi /2}{2 \pi} * 2*\pi * 4.5\\\\\\Arc \ length = \dfrac{1}{2} * 3.14*4.5\\\\\\Arc \ length = 7.065[/tex]

Then the arc length is 7.065 approximately 7.1 cm. Then the correct option is D.

Answer:

1x+1

Step-by-step explanation:

just open the parentheses

Answer:

Step-by-step explanation:

This one-step inequality can be solved by adding the opposite of the constant that is added to x. A number line graph of the solution is attached.

  x -2.6 ≥ 9.4

  x ≥ 12.0 . . . . . . add 2.6 to both sides

The "greater than" relation means that numbers larger than 12 will be included in the solution set. Shading of the number line will be to the right of 12.

The "or equal to" relation means that 12 itself is included in the solution set. This is indicated by a closed circle at 12 on the graph.

Answer:

all i just know is the first question is C

Step-by-step explanation:

Answer: 5/2 liters (or 2.5 liters) of juice were in the jar to start.

The jar was filled at a rate of 5 minutes.

Step-by-step explanation: Firstly, rearrange the equation so that y = mx + b. If you move the x over, you get -2y = -3x -5. To get rid of the -2 in front of the y, divide both sides by -2. Then you get y = 3/2x + 5/2.

The amount of juice in the jar initially is b, also known as the y-intercept.

If you look at the equation, you see that 5/2 is our y-intercept which means the jar initially had 5/2 liters of juice at the start (this is the same as 2.5 liters because 5 divided by 2 is 2.5).

To find the rate at which the jar was filled, you need to solve for x. Plug in the 10 liters for the y and solve.

y = 3/2x + 5/2

10 = 3/2x + 5/2

Now, subtract 5/2 from both sides.

7.5 = 3/2x

Divided both sides by 3/2 to get x alone, which will give you the number of minutes in which the jar was filled.

5 = x

The jar was filled at a rate of 5 minutes.

The central angle (127 degrees) is the angle at point K

The measures of JL and JML are 127 and 233 degrees, respectively

From the complete question, we have:

JL = 127 degrees.

The sum of angles at a point is 360 degrees

So, we have:

JML + 127 = 360

Subtract 127 from both sides

JML = 233

Hence, the measures of JL and JML are 127 and 233 degrees, respectively

Answer:

12 arrangements

Step-by-step explanation:

We solve this question using the Greatest Common Factor method.

We are told that:

She has 36 red carnations, 60 white carnations, and 72 pink carnations.

The same number of each item should be in each basket.

The greatest number of baskets is calculated as follows:

Step 1

The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36

The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

Step 2

We Identify the number that is greatest and common amongst 36,60, and 72

This is 12.

Then the greatest common factor is 12

Therefore, the greatest number of arrangements she can make if she uses every carnation is 12 arrangements

Answer: (2)

Step-by-step explanation:

Answer:

6,138

Step-by-step explanation:

Given the following:

Vocalist needed :

First day (a) = 6

For subsequent days : number doubles

Using the relation. :

Sn = a(r^n -1)/(r -1)

Where a = first term = 6

r = common ratio = r3/r2 = r4/r3

Since number doubles after each consecutive day, then ; r = 2, n = 10

Sn = 6(2^10 -1)/(2 -1)

Sn = 6(1024 - 1) / 1

Sn = 6144 - 6

Sn = 6138

2nd: 6ft

Step-by-step explanation:

I really don't know how just got the answer right.

Answer:

See below.

Step-by-step explanation:

A = (-2/3, 0)

B = (-1/6, 0)

C = (1/2, 0)

D = (4/3, 0)

Step-by-step explanation:

the interval between 0 and 1 shows us, that on that scale the distance between 2 full numbers is split into 6 parts.

so, every little marker represents 1/6.

A goes 4 markers below 0 (left of 0) and is -4/6 = -2/3.

B goes 1 marker below 0 and is -1/6.

C goes 3 markers above 0 (right of 0) and is 3/6 = 1/2.

D goes 2 markers above 1 and is

1 + 2/6 = 6/6 + 2/6 = 8/6 = 4/3 = 1 1/3

please pick the format your teacher wants you to use to write the result.

if you actually need decimals instead of fractions :

-2/3 = -0.666666666...

-1/6 = -0.166666666...

1/2 = 0.5

4/3 = 1.333333333...

The equivalent four-term polynomial which can be created using the x method is,

[tex]x^2 +12x +4x+ 48[/tex]

The factor of a polynomial is the terms in linear form, which are when multiplied together, give the original polynomial equation as result. X-method is the method to find the factors of the polynomial equation.

The polynomial equation is given as,

[tex]x^2 +16x +48[/tex]

An x-method chart shows the product a c at the top of x and b at the bottom of x for the standard polynomial equation. The standard polynomial equation can be given as,

[tex]ax^2+bx+c[/tex]

Comparing the given equation with standard polynomial equation, we get,

[tex]a=1\\b=16\\c=48[/tex]

The x method chart is attached below for the given equation.

The terms 16 x can be divided into the two terms 12x and 4x using the X-method. Thus the equation will become,

[tex]x^2 +12x +4x+ 48[/tex]

Thus, the equivalent four-term polynomial which can be created using the x method is,

[tex]x^2 +12x +4x+ 48[/tex]
