Phantasy [73]

Answer:

Step-by-step explanation:

Sum of all the angles of a triangle = 180°

∠A + ∠B + ∠C = 180°

48 + ∠B + 56 = 180

∠B  + 104 = 180

∠B = 180 - 104

∠B  = 76°

An ice cream store sells 28 flavors of ice cream. Determine the number of 4 dip sundaes.
weeeeeb [17]

Answer:

20,475\ ways

Step-by-step explanation:

we know that

<u><em>Combinations</em></u> are a way to calculate the total outcomes of an event where order of the outcomes does not matter.

To calculate combinations, we will use the formula

C(n,r)=\frac{n!}{r!(n-r)!}

where

n represents the total number of items

r represents the number of items being chosen at a time.

In this problem

n=28\\r=4

substitute

C(28,4)=\frac{28!}{4!(28-4)!}\\\\C(28,4)=\frac{28!}{4!(24)!}

simplify

C(28,4)=\frac{(28)(27)(26)(25)(24!)}{4!(24)!}

C(28,4)=\frac{(28)(27)(26)(25)}{(4)(3)(2)(1)}

C(28,4)=20,475\ ways

If y varies directly as the x^2 and y = 200 when x = 5, what is the value of y when x = -3?
gayaneshka [121]
As the variation is direct we have:
 y = kx ^ 2&#10;
 We must find the value of k.
 For this, we use the following data:
 y = 200 when x = 5
 Substituting values we have:
 200 = k5 ^ 2&#10;
 Clearing k:
 k = 200/5 ^ 2&#10;&#10;k = 200/25&#10;&#10;k = 8
 Then, the function is:
 y = 8x ^ 2&#10;
 We evaluate the function for x = -3
 y = 8 (-3) ^ 2&#10;&#10;y = 8 (9)&#10;&#10;y = 72
 Answer:
 the value of y when x = -3 is:
 c.
