20 points! I need help (asap!!)

EastWind [94]

Answer:

Step-by-step explanation:

We know that the medians of the triangle divides in a ratio of 2:1. Therefore we have the equation:

$\dfrac{9x-9}{2x+8}=\dfrac{2}{1}$ cross multiply

$1(9x-9)=2(2x+8)$ use distributive property a(b + c) = ab + ac

$9x-9=(2)(2x)+(2)(8)$

$9x-9=4x+16$ add 9 to both sides

$9x=4x+25$ subtract 4x from both sides

$5x=25$ divide both sides by 5

$\boxed{x=5}$

$OB=9x-9\to OB=9(5)-9=45-9=\boxed{36}$

$OE=OB:2\to OE=36:2=18\to BE=BO+OE\to BE=36+18=54$

Hellp me solve this thanks

stellarik [79]

Answer:

c. 10 cm

Step-by-step explanation:

The parallel sides of trapizium are the bases so

base 1(B1) =9cm , base(B2)= 12cm

$area(a) = 105 {cm}^{2}$

the perpendicular distance means the height so lets find the height

area of trapizium= B1 + B2 × h

2

${105cm}^{2}(the \: given \: area) = \frac{9cm(the \: given \: base) + 12cm(the \: given \: base)}{2} \times h$

${105cm}^{2} = \frac{21cm}{2} \times h$

now we crisscross

${105cm}^{2} \times 2 = 21cm \times h$

${210cm}^{2} = 21cm \times h$

$\frac{ {210cm}^{2} }{21cm} = \frac{21cm \: }{21cm} \times h$

h = 10 cm

hope u like it ‍❤️‍‍❤️‍‍❤️‍

Suppose Wesley is a marine biologist who is interested in the relationship between the age and the size of male Dungeness crabs.

Eva8 [605]

Answer:

20.24 cm

Step-by-step explanation:

Here, since the age of the crab is given in months and the regression line was computed using the age in months, we just have to replace the value of the age in the formula to estimate the size.

The formula obtained for the estimated size Y was

Y = 9.1411 + 0.4775X

where X is the age in months

Replacing X with 23.2417, we get

Y = 9.1411 + 0.4775*23.2417 = 20.24 cm
