1st calculate the hypotenuse of the right triangle with one side =|-7| and the second side = |-14|
(Hypotenuse)² = 7² + 14² = 625 & Hypotenuse = √625 = 25; now that we have the hypotenuse we can calculate all 6 trigo values:

a) sin Ф = (opposite side) / (hypotenuse) = -14/25  (the student gave a wrong answer).

b) cos Ф = (adjacent) /(hypotenuse) = -7/25 (Right answer)

c) tan Ф = (opposite side) / (adjacent) = -14/ -7 = 14/7 = 2 (the student gave a wrong answer)

d) csc Ф = 1/sin Ф = (1) : (-14/25) = - 25/14 (the student gave a wrong answer)

e) sec Ф = 1/cos Ф = -25/7 ( Right question)

f) cot Ф = 1/tan Ф = 1/2 (the student gave a wrong answer)

A. 

To solve, you need to get the variable by itself. 
Order of operations:
Square root both sides.
(x-5)= plus/minus root 3, as 3 is not a perfect square.
Now you need to add 5 to both sides to get it to disappear on the side with the x.

x=root3 +or - 5, which can be rearranged so that 5 is the first term.

Anyone know this geometry question? Will give brainiest
Dafna11 [192]
The opposite angles equal each other, so X and Z are equal
 using that we solve for x by setting them equal:

6x-60 = 2x+68

subtract 2x from each side:

4x -60 = 68

add 60 to each side:

4x = 128
 divide both sides by 4
x = 128/4
x = 32

now we know x so we can solve everything else by replacing x with 32

WY = 3x+5 = 3(32)+5 = 96+5 = 101

angle Z = 2x+68 = 2(32)+68 = 64+132

the answer is C

Once simplified, which of the expressions below have a value greater than -20?
balandron [24]

Answer:

A, B, and C

Step-by-step explanation:

a). -6 ÷ 2 x 5 1/3

= -3 x 5 1/3

= -16

b). 24 ÷ (-3) + 1/2

= -8 + 1/2

= -7.5

c). 36 ÷ 4 x (-2)

= 9 x -2

= -18

d). -54 ÷ (-9) x (-3 2/3)

6 x -3 2/3

= -22

It takes 5 cups of flour to bake a loaf of bread. How many loaves can be made with 37 cups of flour?
AleksandrR [38]

Answer:

We can make around 7 loaves of bread with 37 cups of flour.

Step-by-step explanation:

Given that 5 cups of flour to bake a loaf of bread.

i.e.

5 cups of flour = 1 loaf of bread

Thus,

37 cups of flour can be determined by dividing 37 by 5.

37/5 = 7.4

        = 7 loaves of bread   (rounding to the whole number)

Therefore, we can make around 7 loaves of bread with 37 cups of flour.

what are the steps to answer this question? Jeff is baking a cake. The recipe says that he has to mix 32 grams of powder to the
Deffense [45]
Well what I would do first is to divide 128 by 32 which I do believe gets you 4. So now you know that 1 cup of powder can make 4 servings. So you now know that each serving only requires 1/4 cup of the powder.

So now we know Jeff went over so now we have Jeff added 2/3 and he only needs 1/4. I would now make them both equivalent by multiplying the numerator and denominator of 2/3 by 4 and the same for 1/4 but instead by 4 multiply it by 3 which you would get 2/3=8/12 and 1/4=3/12. Now subtract the two to get your answer.

8/12-3/12=5/12

Answer: He went over and he needs to remove 5/12 of the cup
