The answer is DE = 27.81 in. Explanation: find the missing angle first, and put it into the equation for the law of sin ( sin(A)/a = sin(B)/b). Solve for the missing length, and you have the missing side to the triangle.

A website charges $0.99 to download a game and a $12.49 membership fee. Write an equation that gives the total cost in dollars (

nata0808 [166]

C = Cost To Download
M = Membership Fee.
T = 0.99C + M

Now, Plug In 6 For C.
And 12.49 For M
T = 0.99 * 6 + 12.49

0.99*6 = 5.94

T = 5.94 + 12.49

5.94+12.49 = 18.43

T = 18.43.

So, If You Want To Buy 6 Games On The Website, It Will Cost $18.43

39. Kate recorded the time it took six children of

scZoUnD [109]

Answer:

$y=-11x+261$

Step-by-step explanation:

As you can observe in the image attached, the line that best fits passes through point B and C. That means we can use those point to find the slope of such line.

$m=\frac{y_{2} -y_{1} }{x_{2}-x_{1} }$

Where $B(11,137)$ and $C(12,126)$

$m=\frac{126-137}{12-11}=-11$

So, the slope of the line that best fits is -11, approximately.

Now, we use the point-slope formula to find the equation.

$y-y_{1} =m(x-x_{1} )\\y-137=-11(x-11)\\y=-11x+124+137\\y=-11x +261$

Therefore, the line that best fits is $y=-11x+261$ approximately.

Remember, when we estimate a line for some data on a scatterplot, we are calculating an approximation, that's why we also said "approximately", because the line is an approximation where the majority of point meet.

4-62. Find the area and perimeter of the below shape. 7.6 ft 3 ft 7 ft 7 ft

stepladder [879]

Answer:

area= 59.5 perimeter=31.6

Step-by-step explanation:

the area of the square is 49 because 7x7=49 and the area of the triangle is 3x7/2 because it is half of a rectangle so it is 10.5 + 49 = 59.5 and perimeter you add all the sides so 3+7.6+7+7+7= 31.6
