The base of right prism is rhombus of diagonal is 6 and 8cm and altitude is 12 cm find total surface area

1 answer:

7 0

E=6
f=8
H=12
h=?
a=?
$(0.5*6)^2+(8*0.5)^2=a^2$
$25=a^2$
a=5
$(0.5*a)^2+(H)^2=h^2$
$(0.5*5)^2+(12)^2=h^2$
h=12.25
Area=0.5*e*f+4*a*h*0.5=0.5*6*8+4*0.5*5*12.25=146.5

Answer:

Step-by-step explanation:

Use the distance formula.

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

We have x1 = 2; y1 = 0; x2 = -6; y2 = 6.

$d = \sqrt{(-6 - 2)^2 + (6 - 0)^2}$

$d = \sqrt{(-8)^2 + 6^2}$

$d = \sqrt{64 + 36}$

$d = \sqrt{100}$

$d = 10$

Answer: 10

Step-by-step explanation:

Given the table:

Month f(x) = Number of imports g(x) = Number of exports

January (1) 3 1

February (2) 4 3

March (3) 5 5

April (4) 6 7

From the table, it is clear that:

Number of imports = number of month + 2

also

Number of exports = 2(number of month) + 1

Therefore, the number of imports equals the number of months plus one. i.e., which is a linear function.

If we compare it with the slope-intercept form of the line

Then,

slope = m = 1

y-intercept = 2

Also number of exports equals is also a linear function.

i.e.

Here,

slope = m = 2

y-intercept = -1

german

Answer:

120x138 in or 11.5x10 feet

Step-by-step explanation:

Step 1:

convert the feet to inches

10(feet)*12(inches)=120 inches

Step 2:

120(width)+18(length)=138 inches

Step 3:

width: 120 in OR 10 feet

length: 138 inches OR 11.5 feet (when divided by 12)

Hope this helps!
