I have 4 triangles to make a trapezium. What is the area of the Trapezium
Please answer

Answer:

subtract 2.4 from both sides,  simplify to -3x=16.8, divide by -3, simplify to x=-5.6.

Step-by-step explanation:

-3x + 2.4 = 19.2

 v     -2.4   -2.4

 v       0      16.8

    -3x=16.8

     -3    -3

       x=-5.6

Answer:

1. 65°

2. 115°

Step-by-step explanation:

1 is a linear pair

2 u just do 180 - 65 =___

that is ur answer

Answer:1. 65 2. 115

Step-by-step explanation:

the opposite side is 65 so is the one directly across it because it’s linear

A straight line is 180 so you subtract 65 from 180 to get 115

Step-by-step explanation:

f(x) = x + 3/ 2

For a

f(2) = 2 + 3 / 2

= ( 4 + 3 ) /2

= 7/2

For b

f(x) = x + 3/2

f^-1(x) = ?

Let y = f(x)

y = x + 3/2

Interchanging the roles of x and y we get,

x = y + 3 / 2

y = x - 3 / 2

Therefore f^-1(x) = x - 3 / 2

For c)

f ^ -1(12) = 12 - 3 / 2

= (24 - 3) / 2

= 21 / 2

Hope it will help :)

Answer:

804.44

Step-by-step explanation:

A=p(1+r/n)^nt

2018-2015=7

7=time(t)

p=535

1=1

r=0.06

n=1

A=535(1+0.06/1)^7

A=535(1.06)^7

A= 535(1.50)

A=804.44

Answer:

− 108 x 5 y 7

Step-by-step explanation:

My computer wont allow it but the 5 and the 7 are exponents

Answer:

[tex]-108x^{5}y^{7}[/tex]

Step-by-step explanation:

Simplify using the laws of exponents (there are more rules than listed, these given rules are just the ones that come into play here);

- when there is a term in parenthesis with an exponent outside, the term's exponent gets multiplied by the exponent outside

- when multiplying two exponents, one can only combine terms with the same base, and one must add the exponents

[tex](3xy^{2})^{3}*(-4x^{3}y)\\\\=(3^{3}*x^{3}*y^{2{^{3}}}) *(-4x^{2}y)\\\\=(27x^{3}y^{6})(-4x^{2}y)\\\\=-108x^{5}y^{7}[/tex]

Without replacement, the probability that all three marbles drawn will be red is 0.01.

Probabiliy is used to determine the likelihood of an event happening. The probability that the event would occur lies between 0 and 1.

Probability of drawing three red marbles = (number of red marbles / total number of marbles) x (number of red marbles / total number of marbles - 1) x (number of red marbles / total number of marbles - 1)

5/17 x 4/16 x 3/15 = 0.01

The probability, to the nearest 10th of a percent, that all three marbles drawn will be red; 1.5%

We are given;

Number of red marbles = 5

Number of blue marbles = 8

Number of Green marbles = 4

Total number of marbles = 5 + 8 + 4

Total number of marbles = 17

Probability of first being red = 5/17

Probability of second being red = 4/16

Probability of third being red = 3/15

Thus;

P(all three marbles drawn are red) = (5/17) * (4/16) * (3/15)

P(all three marbles drawn are red) = 0.0147

Approximating to nearest tenth of a percent = 0.015 = 1.5%

Answer:

The second to last option

Step-by-step explanation:

imagine that the diagram only shows part of each line, or edge. instead, they extend forever in both directions. imagining RQ extending to both sides lets you find other "extended" intersecting lines. in this case, QU and SR

here is an example in ascii art:

___________

|                         |

|___________|

Imagine that the separated lines are instead all sides of a rectangle. My ascii is limited.

Nothing here intersects

__|______________|__

   |                               |

__|______________|__

   |                               |

now you can see intersecting lines. so you can answer the question correctly.

Answer:

A

Step-by-step explanation:

[tex]\frac{(3x^{2} )^\frac{1}{2} }{3^\frac{1}{2} } =3[/tex]

[tex](3x^2)^\frac{1}{2} = 3^\frac{1}{2} x[/tex]

Remember that [tex]\frac{x^b}{x^c} =[/tex]x^(b-c)

Using that [tex]\frac{3^\frac{1}{2}x }{3^\frac{1}{2} }[/tex]=3^(1/2x-1/2)=3^((x-1)/2)

[tex]3^\frac{x-1}{2} =3^1[/tex]

So we can say: [tex]\frac{x-1}{2} =1[/tex], because the bases are the same

We can multiply both sides of the equation by 2. We get x-1=2, and x=3. Which is A.

Answer:

I think it's 15 18 and 5 or 14,12

The solution are (4, 10) and (10, 12).

The phenomenon of unequal or unequal distribution of resources and opportunities among members of a given society is referred to as inequality. In different contexts and for different people, the concept of inequality may mean different things. In addition, there are distinct but interconnected economic, social, and spatial dimensions to inequality. The disjuncture between the moral ethics of equity and social justice, on the one hand, and the normative concept of "deservingness," on the other, adds complexity to debates about inequality.

Given equation of inequality for basket ball and soccer ball

y ≥ 2 + x

where  x is the number of basketballs, and y is the number of soccer balls on display,

situation says  the second number must be at least 2 more than the first number. Also, we are dealing with basket ball and soccer ball, so we won't have negative numbers (Choice E is out) or fractions (Choice B is out).

for choice A: x = 4 and y = 10 (10 is 6 more than 4)

for C: x = 14 and y = 12 (12 is 2 lee than 14 it is not correct)

for D: x= 10 and y = 12  (12 is 2 more than 10)

Hence the option A and D is correct representation for solutions.

Im pretty sure

Im sorry if I was wrong

Step-by-step explanation:

Answer:

15.90

Step-by-step explanation:

if Jos drove 30 miles x is equal to 30 so multiply 0.08 by 30 to get 2.40 then add the base fee to the miles driven fee and the total cost is 15.90.

C= 0.08x + 13.50

C= 0.08(30) + 13.50

C= 2.40 + 13.50
