Emma buys and sells truck parts. She bought two tires for $35.00 each and later sold them for $65.00 each. She bought three rims

Zolol [24]

Answer:

two tires for $35 -------------------------$70 total

three rims for $75--------------------------- $225

five headlights for $ 4.00 ----------------$20

Emma spends ($225+$70+$20) =$315

Now Emma sells them for 2 tires for $65 =130

3 rims for $136 = $408

5 headlights for $15 = $75

total money Emma makes = $613.

the profit is $613- $315= $298

the profit is $298

A rancher has a roll of fencing to enclose a rectangular area. The table shows how the area that the rancher can enclose with th

Free_Kalibri [48]

Checking for each option

Option A: $A(w) = -w^2+200w$

Substitute w = 10 and check if we'd get 900 as the answer
$A(10) = -(10)^2+200(10) = -100+2000 = 1900$

Option B: $A(w) = -w^2+100w$
Substitute w = 10 and check if we'd get 900 as the answer
$A(10)=-(10)^2+100(10)=-100+1000=900$

Option C: $A(w)=w^2+40w$
Substitute w = 10 and check if we'd get 900 as the answer
$A(10) = 10^2+40(10)=100+400=500$

Option D: $A(w) = w^2+90w$
Substitue w = 10 and check if we'd get 900 as the answer
$A(10)=10^2+90(10) = 100+900=1000$

Suppose line segment AB has one endpoint at A(0, 0). What are the coordinates of B if (5, 3) is 1/3 of the way from A to B?

prisoha [69]

Answer:

$B(x_2,y_2)= (20,12)$

Step-by-step explanation:

Given

$A = (0,0)$

$Ratio; m : n = 1 : 3$

$Point\ at\ 1 : 3 = (5,3)$

Required

Coordinates of B

This question will be answered using line ratio formula;

$(x,y) = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})$

In this case:

$(x,y) = (5,3)$

$(x_1,y_1) = (0,0)$

$m : n = 1 : 3$

Solving for $(x_2,y_2)$

$(x,y) = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})$ becomes

$(5,3) = (\frac{1 * x_2 + 3 * 0}{1 + 3},\frac{1 * y_2 + 3 * 0}{1 + 3})$

$(5,3) = (\frac{x_2 + 0}{4},\frac{y_2 + 0}{4})$

$(5,3) = (\frac{x_2}{4},\frac{y_2}{4})$

Comparing the right hand side to the left;

$\frac{x_2}{4} = 5$ -- (1)

$\frac{y_2}{4} = 3$ -- (2)

Solving (1)

$x_2 = 5 * 4$

$x_2 = 20$

Solving (2)

$y_2 = 3 * 4$

$y_2 = 12$

Hence;

$B(x_2,y_2)= (20,12)$

the altitude of the hypotenuse of a right triangle divides the hypotenuse into segments of lengths 14 and 8. what is the length

lisov135 [29]

Answer:

B. $4\sqrt{7}$

Step-by-step explanation:

The right triangle altitude theorem states that the altitude of a right angled triangles formed on the hypotenuse is equal to the geometric mean of the 2 line segments it creates.

This can be represented as:

$h = \sqrt{(xy)}$
