M=30° because the right angle and 60 degree angle equal 150 and 180 (degrees in a triangle) minus 150 is 30

n=50° because 40 plus the right angle is 130 then the difference between that and 180 is 50 then n is the vertex angle of the one you found

t=98° because answer n plus the other part to the straight angle including the 112° angle is 68 then the total angle turns to 118 then the final angle turns to 62 via earlier reasoning, then because of another straight angle t=98

use the earlier reasoning to fine the other answers of

p=71°
q=39°

use the angle degrees formula to get Pentagon's maximum angles then use earlier resources

the final answers u should be able to figure out from there and u will never learn unless you do some yourself

What is the inverse of the function f(x) = 2x – 10?

noname [10]

Answer:

The inverse f-1(x) = ( x + 10)/2.

Step-by-step explanation:

f(x) = 2x - 10

Find x in terms of f(x):

2x = f(x) + 10

x = (f(x) + 10))/ 2

Replace x by the inverse f-1(x) and f(x) by x:

f-1(x) = (x + 10)/2.

Which graph shows the equation c = 10+ 3t, where c is the total cost of going to the carnival and t is the number of $3 tickets

Vladimir [108]

we have

$c = 10+ 3t$

where

c---------> is the total cost of going to the carnival

t---------> is the number of $\$3$ tickets purchased

we know that

<u>the domain of the function is the interva</u>l---------------> [0,∞)

Because the number of tickets can not be negative

<u>The range of the function is the interval</u>-------------> [10,∞)

Because the total cost can not be negative

using a graph tool

see the attached figure

The endpoints of AB are A(1,4) and B(6,-1).

kykrilka [37]

Answer:

C(3, 2)

D(2.2, 2.8)

Step-by-step explanation:

If point $M(x,y)$ divides the segment AB with endpoints $A(x_1,y_1)$ and $B(x_2,y_2)$ in the ratio $m:n,$ then its coordinates are

$x=\dfrac{n\cdot x_1+m\cdot x_2}{m+n}\\ \\y=\dfrac{n\cdot y_1+m\cdot y_2}{m+n}$

You are given A(1,4) and B(6,-1).

1. If point C divides AB in the ratio 2 : 3, the coordinates of point C are

$x=\dfrac{3\cdot 1+2\cdot 6}{2+3}=\dfrac{3+12}{5}=\dfrac{15}{5}=3\\ \\y=\dfrac{3\cdot 4+2\cdot (-1)}{2+3}=\dfrac{12-2}{5}=\dfrac{10}{5}=2$

C(3, 2)

2. If point D divides AC in the ratio 3 : 2, the coordinates of point D are

$x=\dfrac{2\cdot 1+3\cdot 3}{3+2}=\dfrac{2+9}{5}=\dfrac{11}{5}=2.2\\ \\y=\dfrac{2\cdot 4+3\cdot 2}{3+2}=\dfrac{8+6}{5}=\dfrac{14}{5}=2.8$

D(2.2, 2.8)

50 people purchase item 5(the item 5 cost $18.94) seven of these customers use a coupon for 15% off. how much money do you make

andrezito [222]

Answer:

$927.113

Step-by-step explanation:

50-7=43

43×18.94=814.42

100-15=85

100%=18.94

what about 85%

85×18.94=1609.9÷100=16.099

16.099×7=112.693

814.42+112.693= 927.113
