How do you find the value of equal angles y and x?

Because we know the triangles are similar and the angle of D = angle of A, that means that the angle of B = angle of E and angle of C = angle of F. Therefore, angle of C = 78 degrees and angle of E = 64 degrees. The angles of a triangle sum to 180 degrees, so we have the equation: x + 64 + 78 = 180. Solving for x gives you x = 38 degrees, which is the same as angle y.

They are similar
So
B = E
C = F
x° = y°

x = y = 180° - 64° - 78° = 38°

X - y = 5
y = x - 5

For domain {0, 2, 4}, range = {0 - 5, 2 - 5, 4 - 5} = {-5, -3, -1}

A company charting its profits notices that the relationship between the number of units sold, x, and the profit, P, is linear.

scoundrel [369]

Answer:

P(x) = 58x - 8,500

Step-by-step explanation:

The profit function can be modeled based on the two given points of format (P, x) that are ($1360, 170) and ($4260, 220). The slope of the function is:

$m=\frac{4,260-1,360}{220-170}\\ m=58$

Applying the general form of a linear equation, the profit function is:

$P-P_0 = m*(x-x_0)\\P - 1,360=58*(x-170)\\P(x) = 58x -8,500$

The profit as a function of units sold is P(x) = 58x - 8,500.

you are going to give each customer 12fl oz of lemonade.If you have 15 gallons of lemonade prepared, how many customers will you

zimovet [89]

Answer:

160

Step-by-step explanation:

so 1 gallon is 128 fluid ounces

how many is 12fl oz

so (1×12)/128=0.09375gallons per person

and you have 15 so if one consumes 0.09375 how many can consume 15

so 15/0.09375
