Answer:

m<C  = 36.87degrees

Step-by-step explanation:

Solve for the approximate measure of angle C.

From the given diagram;

AC is the hypotenuse

BC is adjacent to <C

Cos m<C = adj/hyp

Cos m<C = BC/AC

Cos m<C = 20/25

Cos m<C = 0.8

m<C = arccos (0.8)

m<C  = 36.87degrees

The first term of a sequence is a multiple of 3 The second term of this sequence is 6 less than the first term. The third term i
Mekhanik [1.2K]

Answer:

First term = 15

Second term = 9

Third term =  3

Step-by-step explanation:

Given,

First term = 3x

Second term = 3x - 6

Third term =  \frac{1}{5} (3x) =  \frac{3x}{5}

Also,

3x -  \frac{3x}{5}  = 12

\frac{15x}{5}  -  \frac{3x}{5}  = 12

\frac{15x - 3x}{5}  = 12

15x - 3x = 12 \times 5

12x = 60

x =  \frac{60}{12}

x = 5

With the value of x, we conclude that the first three terms are as follows:

First term = 3x = 3×5 = 15

Second term = 3x - 6 = 15 - 6 = 9

Third term = \frac{3x}{5} =\frac{15}{5}= 3

Dennis can walk 2.833 miles each hour . About how far can he walk in 3 hours and 15 minutes
Bezzdna [24]

well, let's split the hours in minutes, so since 1 hr is 60 minutes, so he can walk 2.833 miles in 60 minutes, well, 3 hrs is 3*60 = 180 minutes, then we add 15 minutes, that's 195 minutes.

if he can walk 2.833 miles in 60 minutes, how long will it be for 195 minutes?

\bf \begin{array}{ccll} miles&minutes\\ \cline{1-2} 2.833&60\\ x&195 \end{array}\implies \cfrac{2.833}{x}=\cfrac{60}{195}\implies \cfrac{2.833}{x}=\cfrac{4}{13} \\\\\\ 36.829=4x\implies \cfrac{36.829}{4}=x\implies 9.20725 = x

A bag of skittles has 50 pieces of candy what percentage is orange ps. there are 11 orange skittles
Oliga [24]

Answer:

I think the answer is 22% but I am not sure

Step-by-step explanation:

Percentage solution with steps:

Step 1: We make the assumption that 50 is 100% since it is our output value.

Step 2: We next represent the value we seek with X

Step 3: From step 1, it follows that 100%=50

Step 4: In the same vein, x%=11.

Step 5: This gives us a pair of simple equations:

100%=50(1).

X%=11(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the left hand side of both equations have the same unit; we have

100% / X% = 11 / 50

X = 22%

Step 7: Taking the inverse (or reciprocal) of both sides yields

X% / 100% = 11 / 50

Therefore, 11 is 22% of 50.
