Which fractions are equivalent to 4/9?

Answer:

b.) 76

Step-by-step explanation:

A triangles angles will always add up to a total of 180°.Since both angles B and C are x, they have the same value. So to find their value, add the choices to 28 twice until you get 180:

[tex]28+76+76=180[/tex]

Or, you can make and equation. 180 on one side of the equation. On the other side, put both x's (2x) plus the value of angle A:

[tex]2x+28=180[/tex]

Solve for x:

[tex]2x+28-28=180-28\\2x=152\\\\\frac{2x}{2}=\frac{152}{2}\\ x=76[/tex]

Finito.

Answer:

Value of tax liability will be zero

Step-by-step explanation:

Given:

Total estate value = $2,186,000

Estate tax = 40 %

Find:

Heir's tax liability = ?

Computation:

Total taxable estate = Total estate value - Estate Exemption

Note: According to Exhibit 19-6 for Estate Exemption, Estate Exemption  is 11.4 million.

We know that Estate Exemption  is higher than total estate value, therefore will be no tax liability on the successor, so the value of tax liability will be zero.

Answer:

A

Step-by-step explanation:

To calculate this, we shall be selecting 2 each from a total of 64

This is a combination question and our required answer is 64C2

Mathematically, if we are to select r from n items , the combination can be computed as follows;

nCr = n!/(n-r)!r!

Thus, we have 64C2 as ; 64!(64-2)!2! = 64!/62!2!

= (64 * 63 * 62!)/62!2! = (64 * 63)/2 = 32 * 63 = 2,016 pairings

Answer:

The product of the real and complex number given is -10+40i

Step-by-step explanation:

The general form of a complex number is expressed as z = x+iy where

x is the real part and y is the imaginary part.

Given a complex and a real value as shown

z1 = −2+8i and z2 = 5+i0

Taking their product;

z1z2 = (−2+8i)(5+i0)

z1z2 = -10+0+40i+0

z1z2 = -10+40i

According to the product of the complex numbers, the resulting real part is -10 and the complex part is 40.

The representation on the complex plane is as shown in the attachment.

The complex number −2+8i has modulus of (1. 2√17)

When −2+8i is multiplied by 5, the modulus of the product is (2. 10√17)

Multiplying a complex number by a real number results in a scalar of the complex number. The quadrant location of the complex number and its product with (3. a positive real number) are the same.

Step-by-step explanation:

We are gonna use "dollars" instead of "soles.

According to the problem, tickets cost $30 for adults and $20 for children.

Last Saturday assisted 248 people which gave a total of $5930.

To know the number of adults and children were there, we need to defined a system of equations.

[tex]x+y=248\\30x+20y=5930[/tex]

Where [tex]x[/tex] represents adults and [tex]y[/tex] represents children.

First, we multiply the first equation by -20

[tex]-20x-20y=-4960[/tex]

Then, we sum this equation with the second one

[tex]10x=970\\x=97[/tex]

There were 97 adults.

Now, we use this value to find the other one

[tex]x+y=248\\97+y=248\\y=248-97\\y=151[/tex]

There were 151 children.

Therefore, 97 adults and 151 children assisted to that show.

Answer:

b

Step-by-step explanation:

y= -3x+7

Answer:

The answer is option 2.

Step-by-step explanation:

It is given that the slope of the line is -3 so you just have to substitute it into the slope-form equation, y = mx+b where m is gradient and b is y-intecept. In order to find b value, you have to put in the coordinates :

[tex]y = mx + b[/tex]

Let m = -3,

[tex]y = - 3x + b[/tex]

At (1,4),

[tex]4 = - 3(1) + b[/tex]

[tex]4 = - 3 + b[/tex]

[tex]b = 4 + 3[/tex]

[tex]b = 7[/tex]

[tex]y = - 3x + 7[/tex]

Answer:

61°

Step-by-step explanation:

∠SPQ is a straight line, so it equals to 180°.

∠SPR is 119° and since we're looking for ∠QPR, we subtract 119° from 180°.

180° - 119° = 61°, so ∠QPR = 61°

Answer:

61 degrees

Step-by-step explanation:

Because SPQ is said to be a straight line, we know that a straight line in this kind of equation is equal to 180 degress.

Since we already know the measure to one angle (119), we would need to find the difference between 180 and 119, meaning we'd have to subtract.

(180-119)

Then we would just get the sum, which in this case, is 61 degrees.

Answer:

[tex]y=18(1.15)^x[/tex]

Step-by-step explanation:

The initial value of the poster =$18

Its value increases by 15% each year.

We can model this using the exponential growth function.

[tex]y(x)=y_0\cdot r^x $ where y_0$ is the initial value and r is the growth factor.[/tex]

Growth Factor, r=1+0.15=1.15

Therefore:

[tex]y(x)=18(1.15)^x[/tex]

After 1 year, when x=1

[tex]y(1)=18(1.15)^1=\$20.70[/tex]

This is true.

Therefore, the model is valid and its value, y after x years will be:

Step-by-step explanation:

Negative 4 x + 6 y = negative 18 and y = negative 2 x + 21

convert to algebra.

- 4x + 6y = -18 ;

y = -2x + 21;

let us solve this with elimination

change -4x + 6y = -18  to  -2x + 3y = -9

get:  -2x  + 3y = -9

and  2x + y = 21

add.

-2x + 2x + 3y + y = -9 + 21

4y = 12

y = 3

2x + (3 ) = 21

Answer:

The distance between opposite corners of the living room is 30ft

Step-by-step explanation:

This can be thought of as a right triangle and we want to know its hypotenuse

To calculate one side of a right triangle from the other 2 sides we have to use Pythagoras

h = hypotenuse

a = leg 1 = 18ft

b = leg 2 = 24ft

h² = a² + b²

we replace the known values

h² = (18ft)² + (24ft)²

h² = 324ft² + 576ft²

h² = 900ft²

h = √(900ft²)

h = 30ft

The hypotenuse is 30ft

Answer:

The concentration is 12M

Step-by-step explanation:

In this question, we are asked to calculate the concentration of the alkali given the information in the question.

To answer this question correctly, the first thing to do is to write the complete chemical equation of the reaction of the acid and the alkali. We identify that LiOH is the alkali and HCl is the acid

LiOH + HCl ———-> LiCl + H2O

we can deduce that 1 mole of the acid used up a mole of the base.

Now, we use the titration formula;

CaVa/Na. = CbVb/Nb

since Na= Nb = 1 i.e number of moles , we can just write the formula to be

CaVa. = CbVb

Where Ca is the concentration of the acid which is 4M

Va is the volume of acid used which is 60mL

Cb is the concentration of the base which is ?

Vb is volume of base which is 20mL

Plugging these values, we have;

4 * 60 = Cb * 20

Cb = 240/20

Cb = 12M

The concentration of the base is thus 12M

Answer:

10 ft

Step-by-step explanation:

area of trapezoid = (B + b)h/2

where B and b are the lengths of the bases, and h is the height.

A = (B + b)h/2

115 = (19 + 4)h/2

230 = 23h

23h = 230

h = 10

Answer: 10 ft

The height of the trapezoid with base lengths of 4 and 19 feet and an area of 115 square feet is 10 feet.

A trapezoid is a quadrilateral which is having a pair of opposite sides as parallel and the length of the parallel sides is not equal.

The area of a trapezoid is given as half of the product of the height(altitude) of the trapezoid and the sum of the length of the parallel sides.

[tex]\rm{ Area\ of\ trapezoid = \dfrac{1}{2} \times Height \times(Sum\ of\ parallel\ sides)[/tex]

The area of a trapezoid is given as half the product of the sum of the parallel sides and the height of the trapezoid.

The length of the parallel sides of the trapezoid is 4 and 19 feet, while the area of the trapezoid is 115 square feet. Therefore, the height of the trapezoid is,

115 ft² = 0.5 × (4 ft + 19 ft ) × height

115 ft² = 0.5 × 23 ft × height

height = (115 ft²)/ (0.5 × 23 ft)

height = 10 feet

Hence,  the height of the trapezoid is 10 feet.

Answer:

The probability of choosing tiles which sum is 12 is 1/21

Step-by-step explanation:

The numbers we have is 1.2,3,4,5,6 and 7

The sum we are looking at is 12. The only sum that can give us this sum is the addition of 7 and 5

There are only two ways we can make this selection if order matters.

Either we pick 5 first then 7 second or 7 first and 5 second

The probability of picking a 5 first will be 1/7, since it is without replacement , the probability of picking a 7 next will be 1/6

The joint probability here would thus be 1/7 * 1/6 = 1/42

In the other second case where we are picking a 7 first and a 5 second, the probability here will be the same as first just that we reversed the other. Hence, the probability here is also 1/42

Now, the probability of either of the two orders happening will be 1/42 + 1/42 = 2/42 = 1/21

Final answer:

The probability of choosing tiles whose sum is 12 is 1/49.

Explanation:

Probability of choosing tiles whose sum is 12:

Number of favorable outcomes: 1 (getting two tiles that sum up to 12, which is 6+6)Total number of possible outcomes: 7*7 = 49 (as there are 7 choices for each tile)Probability = Number of favorable outcomes / Total number of possible outcomes = 1/49
