Work out the area of this trapezium. 4cm 13cm 5cm 19cm pls help you be brainliest

Answer:

14 in^3.

Step-by-step explanation:

The volume = volume of the bottom prism + volume of the top pyramid

= area of base * height of the prism + 1/3 * area of base * height of the pyramid

= 2 * 1.5 * 4 + 1/3 * (2*1.5) * 2

= 3*4 + 1/3 * 6

= 14 in^3.

Answer:

Step-by-step explanation:

you can use the side angle side formula  ( a form of Law of Cosines)

a^2 = b^2 + c^2 − 2bc cos(A)

where x = a  , then

[tex]x^{2}[/tex] =  [tex]5^{2}[/tex] +[tex]3^{2}[/tex] - 2*5*3*cos(107)

[tex]x^{2}[/tex] = 25 + 9 - 30 * (-0.292371)

[tex]x^{2}[/tex] = 25 + 9 -8.7711511

x = 5.0228 cm

Answer:

[tex]\Large \boxed{\sf 144 \ ft^2}[/tex]

Step-by-step explanation:

Find the area of the 4 triangles and 1 square and add them.

Area of triangle = base × height × 0.5

Area of square = s²

[tex](9 \times 6 \times 0.5\times 4)+(6^2)=144[/tex]

Answer:

m = 3/2

Step-by-step explanation:

You want to find the slope, or the change in y coordinates over change in x-coordinates.

The first given point is E(-2, -4)

The second point is F(2, 2)

Coordinates are given in (x, y), so following the equation and computing the  x and y coordinates of E - F for both the numerator and denominator:

[tex]\frac{y_2 - y_1}{x_2-x_1} = \frac{-4 -2}{-2 -2} = \frac{-6}{-4} = \frac{3}{2}[/tex]

You could also have went the other way and calculated F - E for the numerator and denominator and get the same answer.

Finally, to check you can also look at the graph through the rise over run (rise/run) method and see that from E, you go up 3 (rise) and to the right 2 (run) to get to the next point on the line.

Answer:

[tex]1600\ \text{people per square mile}[/tex]

Step-by-step explanation:

Number of people per square mile in City A is 6000.

In terms of size City B is a dilation of City A with scale factor 1.5.

This means a length of 1 mile in city A would be 1.5 miles in city B.

So, [tex]1\ \text{mile}^2\text{ in City A}=1.5^2\ \text{mile}^2\text{ in City B}[/tex]

City B has [tex]\dfrac{3}{5}[/tex] of the population of City​ A.

So the population density of City B would be

[tex]\dfrac{\dfrac{3}{5}\times 6000}{1.5^2}=1600\ \text{people per square mile}[/tex]

The population density of City​ B is [tex]1600\ \text{people per square mile}[/tex].

Step-by-step explanation:

The average rate of change will be "55 m/h".

According to the question,

→ After 2 hours (t₁),

Juan is 110 miles (d₁) from his home.

→ After 5 hours (t₂),

Juan is 275 miles (d₂) from his home.

→ The average rate of change will be:

= [tex]\frac{d_1+d_2}{t_1+t_2}[/tex]

By substituting the values, we get

= [tex]\frac{110+275}{2+5}[/tex]

= [tex]\frac{385}{7}[/tex]

= [tex]55 \ m/h[/tex]

Answer:

y = x^2 + 14x + 62

Step-by-step explanation:

y = (x + 7)^2 + 13 is to be rewritten in the form y = ax^2 + bx + c.  

Note:  Use " ^ " to denote exponentiation.

Expand y = (x + 7)^2, holding the constant term to be added on later:

y = x^2 + 14x + 49 + 13

Combining the constants, we get:

y = x^2 + 14x + 62 (which matches Answer D).

Answer:

53.3 in^2

Step-by-step explanation:

Given data

Base B= 13in

Height H= 8 1/5 in= 41/5in

The expression for the area of a triangle is

Area= 1/2 Base * Height

Substitute

Area= 1/2* 13* 41/5

Area= 6.5*41/5

Area= 266.5/5

Area= 53.3 in^2

Hence the area is 53.3 in^2

Answer:

D because it on the same plane as abc so it is a coplanar. also I got it right on my test.

Point D is coplanar with A, B, and C because it is on the same plane as A, B, and C option (4) is correct.

It is defined as the six-faced shape, a type of hexahedron in geometry.

It is a three-dimensional shape. It is also called a cuboid.

It is given that:

A rectangular prism is given,

Geometry can be defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.

As we know in the rectangular prism there are eight vertices and six faces.

From the figure, we can see clearly that point D is coplanar with A, B, and C.

Point D is coplanar with A, B, and, C.

Thus, point D is coplanar with A, B, and C because it is on the same plane as A, B, and C option (4) is correct.

So you're left with sqrt x-4 ^2

Then reduce the index of the radical and the exponent with 2

x-4

Hope this helps

The correct expression will be ( x- 4 ). So option B is right.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The expression will be solved as:-

E = ( - √(x-4))²

The product of two minuses is positive and the product of the same square root numbers will be the number so the equation will become.

E = -√(x-4) x -√(x-4)

E = x - 4

Therefore the correct expression will be ( x- 4 ). So option B is right.

The amount of money in the bank contains 5 pennies, 9 nickels, 21 dimes, and 15 quarters.

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown.

First, let's find the number of pennies in the bank.

Since 10% of the coins are pennies, and there is 50 coins total, the number of pennies is :

10/100 × 50 = 5

Now let's find the number of dimes. Since 42% of the coins are dimes, and there is 50 coins total, the number of dimes is :

42/100 × 50 = 21

Since there are 4 more nickels than pennies, the number of nickels is :

5 + 4 = 9

Finally, the number of quarters is: 50 - 5 - 9 - 21 = 15

Thus, the bank contains 5 pennies, 9 nickels, 21 dimes, and 15 quarters.

Answer:

The [tex]pH[/tex] of the clean compound is approximately 10.495.

Step-by-step explanation:

If the cleaning ion concentration of the cleaning compound is [tex][H^{+}] = 3.2\times 10^{-11}[/tex], then the [tex]pH[/tex], no unit, of the compound is:

[tex]pH = -\log_{10} [H^{+}][/tex]  (1)

[tex]pH = -\log_{10} (3.2\times 10^{-11})[/tex]

[tex]pH = -\log_{10} 3.2 - \log_{10} (10^{-11})[/tex]

[tex]pH = -\log_{10} \frac{32}{10} +11[/tex]

[tex]pH = -\log_{10} 32 + \log_{10} 10 + 11[/tex]

[tex]pH = -\log_{10} 32 +12[/tex]

[tex]pH \approx 10.495[/tex]

The [tex]pH[/tex] of the clean compound is approximately 10.495.
