Find the surface area of the composite solid 6 ft 4 ft 5 ft 5 ft
The surface area of the composite solid is 165 [tex]feet^2[/tex].
We possess
4 triangles, each measuring 6 feet in height and 5 feet in base
4 rectangles, each measuring 5 feet long and 4 feet wide
1 square has side a = 5 feet.
The formula for a triangle's area is:
[tex]A_T=\frac{1}{2} bh[/tex]
Substitute:
[tex]A_T=\frac{1}{2} 5*6\\A_T=\frac{1}{2} 30\\A_T=15 ft^2[/tex]
Formula for calculating a rectangle's area:
[tex]A_R=lw[/tex]
Substitute:
[tex]A_R=5*4\\A_R=20 ft^2[/tex]
The formula for a square's area is as follows:
[tex]A_s=a^2[/tex]
Substitute:
[tex]A=s=5^2\\A_s=25 ft^2[/tex]
The composite solid's surface area is:
[tex]SA=4A_T+4A_R+A_s[/tex]
Substitute:
[tex]SA=4*15+4*20+25\\SA= 60+80+25\\SA=165 ft^2[/tex]
The composite solid has a surface area of 165 [tex]feet^2[/tex].

Answer: 65in
Step-by-step explanation:
Break the trapezoid into a rectangle (8in by 10in) and the leftovers are 2 triangles. Find the area for the triangles. Because the top of the trapezoid is 10in and the bottom is 15in, then we know that 15-10 = 5 and that the triangles are 2.5in by 8in. Because the triangles are the same congruent, then just multiply 8 by 2.5 to get 20.
Find the middle part now, which is 8 times 10 to get 80. Then 80 + 20 = the area of the trapezoid.
Lastly, subtract the non shaded region (7x5=35) and then 100-35 = 65

what is the area of the white box
Answer:
12 m²Step-by-step explanation:
The white box is a rectangle with width of:
a = 2 m
and length of:
b = 7 m - 1 m = 6 m
So its area is A = 2 m × 6 m = 12 m²
{The shaded blue area is: (5 m + 1 m)(8 m) - 12 m² = 48 m² - 12 m² = 36 m²}
Given klmn is a trapezoid, kl = mn, m<1 = m<2, lm/kn = 8/9, pklmn = 132. Find: the length of the legs
Answer:
The length of legs lm, mn, and lk is 32 while that of kn is 36.
Step-by-step explanation:
The diagram is attached in the answer.
As both the angles are equal thus the two forms isosceles triangles. This is true because the converse of base angle theorem is applicable here. The theorem clearly states that when a trapezoid is divided by the diagonal, it forms two set of angles where m<1=m<2 and m<lmk=m<nmk
This leads the two set of legs such as
[tex]\dfrac{lm}{kn}=\dfrac{8}{9}[/tex]
Or this could be written as
[tex]lm=8x\\kn=9x[/tex]
Now the remaining two sides are given as
[tex]lk=lm[/tex] as this form an isosceles triangle so
[tex]lk=8x[/tex]
Similarly
[tex]mn=lm\\[/tex]
Or
[tex]mn=8x[/tex]
Now the perimeter is given as
[tex]\text{perimeter}=lm+mn+kn+lk\\[/tex]
Here perimeter is given as 132 so this gives:
[tex]\text{perimeter}=lm+mn+kn+lk\\132=8x+8x+8x+9x\\132=33x\\x=\dfrac{132}{33}\\x=4[/tex]
So the four legs are of length as given below:
[tex]lm=8x=8\times 4=32\\mn=8x=8\times 4=32\\lk=8x=8\times 4=32\\kn=9x=9\times4=36[/tex]
So the length of legs lm, mn, and lk is 32 while that of kn is 36.
Which logarithmic equation is equivalent to this exponential equation?
12=5^x
Given:
The equation is:
[tex]12=5^x[/tex]
To find:
The logarithmic equation that is equivalent to the given exponential equation.
Solution:
According to the property of logarithm:
[tex]a=b^x\Leftrightarrow \log_b a=x[/tex]
We have,
[tex]12=5^x[/tex]
Here, [tex]a=12,b=5[/tex]. By using the above property of logarithm, we get
[tex]\log_{5}12=x[/tex]
[tex]x=\log_{5}12[/tex]
Therefore, the correct option is C.

Line / is shown on the graph below. If another line is drawn, perpendicular to line I, what must be its slope?
Answer:
Undefined
Step-by-step explanation:
The slope on the graph is horizontal so there's no slope and the answer is just y = 3
For a line to be perpendicular to a horizontal line, it is going to be a vertical line.
All vertical lines have an undefined slope.

Step-by-step explanation:
In the equation, [tex]ax^2+bx+c=0,[/tex] the discriminant can be found with [tex]b^2-4ac[/tex].
In this equation,
the discriminant would be: [tex](-10)^2-4(2)(-5)=100+40=140[/tex]
Answer:
D. 140
Step-by-step explanation:
D = b² - 4ac
So, let's identify our values.
a = 2
b = -10
c = -5
Now, we can plug in our values.
D = -10² - 4(2)(-5)
D = 100 + 40
D = 140

El 15% de las ventas de un comercio ha sido de productos que valían 100€ o más. Si se han realizado 595 ventas de productos que valían menos de 100€, ¿que numero de ventas se han realizado en total?
Answer:
700 total sales
Step-by-step explanation:
The computation is shown below:
After 15% discount i.e.
= 100 - 15
= 85%
Now
85% = 595 sales of less than € 100
So,
15% = x sales of € 100 or more than € 100
After this
(595 × 15) ÷ 85 = 105 sales of € 100 or more than € 100
The number of total sales is
= 595 + 105
= 700 total sales
Find g(-4) if g(x) = 8x^2 + 4x
Answer:
x = - 4
[tex]g(x) = 8 {x}^{2} + 4x[/tex]
g(- 4) =?
[tex]g( - 4) = 8( { - 4)}^{2} + 4( - 4) \\ g( - 4) = 8 \times 16 - 16 \\ g( - 4) = 128 - 16 \\ g( - 4) = 112[/tex]
=> g (- 4) = 112.

Levi and his family belong to a family share plan for their cell phones. The pan includes unlimited minutes, text, and

many as 12 lines. Complete the table to determine the cost for each plan member. Write a function that can be used
to determine the cost per month, y, for each plan member, X.
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of calculations of bills.
The bill calculation goes as equation,
y = $250 + n*($10)
here, n = number of lines,
1.) For n = 2 , Y = cost = 250 + 20 = $270
2.) for n = 4 , Y = $290
3.) for n = 6 , Y = $310
4.) for n = x, Y = $250 + x*($10)
for lastly 12 members we get as,
Y = 250 + (12)*(10) = 250+120 = $370
