Answer:

94 minutes

Step-by-step explanation:

To get to 9:00, we add 6 minutes. From 9 to 10, there's 60 minutes. From 10 to 10:28, there's 28 minutes.

If we add them all together we get 94 minutes or 1 hour and 34 minutes.

Hope this helps.

If tanx = 0.75, what is the value of cosx + sinx ?
kap26 [50]
Cosine (x) = 4 over 5
cos
(
x
)
=
4
5
Explanation:
First you must apply sohcahtoa
it means
sine = opposite side over hypotenuse
sine = opposite/hypotenuse
cosine = adjacent side over hypotenuse
cosine = adjacent/hypotenuse
tangent = opposite side over adjacent side
tangent = opposite/adjacent
then
solve the unknown by applying the Right Triangle Theorem.
draw a right triangle.
label the parts where
a
is the opposite side
b
is the adjacent side
c is the hypotenuse
Solve the unknown. The hypotenuse using
a
2
+
b
2
=
c
2

since the given
tan
x
=
3
4

it means
tan = opposite/adjacent
a
= opposite side =
3

b
= adjacent side =
4

c
= hypotenuse = ??
a
2
+
b
2
=
c
2

substitute the value
(
3
)
2
+
(
4
)
2
=
c
2

9
+
16
=
c
2

25
=
c
2

get the square root of
25

it is equal to
5

therefore
c
=
5

c
= hypotenuse =
5

cos
= adjacent/hypotenuse
cos
(
x
)
=
4
over
5

cos
(
x
)
=
4
5

4. If 4 bananas weigh 4 4/5 kilograms , how
quester [9]

Answer:

It's the same process, change 4 4/5 to an improper fraction = 24/5 then set up a proportion

4 bananas/(24/5) kg = 3 bananas/x kg take cross products

4x = 3 (24/5) = 72/5  divide by 4 (this is the same as multiplying by 1/4)

x = 72/20, change this to a mixed number = 3 12/20 = 3 3/5 kg
