A) The correct way to write 1/4 as a precent is 25%.

because....

1÷4= .25. and .25×100= 25%

b) The reporter most likely forgot to multiply by 100. The reporter instead just found what 1/4 was as a decimal, not a precent.

Given cos t = 1/2 tan 0 find sin (t) and sec (t)
777dan777 [17]

Answer:

Sin(t) =  \frac{\sqrt{3} }{2} } and sec(t) =2

Step-by-step explanation:

The secant function is the reciprocal function of the cosine function. Therefore, given that sec(t) = \frac{1}{cos(t)} then, if  cos(t) = \frac{1}{2} then  sec(t) =2.

On the other hand, if cos (t) = 1/2 ⇒ t = ±\frac{\pi}{3}

Then, the sin(\frac{\pi}{3}) = \frac{\sqrt{3} }{2} }

I added three non-unit fractions together to make a whole. What three fractions could that be?
Anna11 [10]

Answer:

For example \frac{2}{6}

Step-by-step explanation:

A non-unit fraction is a fraction of which the numerator is not equal to one. Additionally, the question does not state to pick three different ones and thus you can pick any fraction that when multiplied by three (since you take three fractions together) add up to a whole number (I'm picking the whole number to be one here just to make it simple), where the numerator is not equal to one of course.

For example:    \frac{2}{6}, because 3·    \frac{2}{6} =      \frac{6}{6} = 1

Infinitely many solutions can be found: for example \frac{3}{9} , \frac{4}{12} , etc

Ne4ueva [31]

Answer:

Serena will have $9.75 left after her purchases.

Step-by-step explanation:

5 packages of buns= 3.85x5= 19.25

5 packages of hotdogs= 4.20x5= 21

19.25+21= 40.25

50-40.25= 9.75

Find the value of d and YZ if Y is between X and Z.
docker41 [41]

Y is between X and Z

The value of d=2 and the value of YZ = 16

Given :

Y is between X and Z.

XY = 11d, YZ = 9d – 2, XZ = 5d + 28

We need to find the value of d

we know that Y is between X  and Z

So, XZ=XY+YZ

Replace the given expression and solve for d

XZ=XY+YZ\\5d+28=11d+9d-2\\Combine \; like \; terms\\5d+28=20d-2\\Subtract \; 5d\\28=15d-2\\\\Add \; 2\\30=15d\\Divide \; by \; 15\\d=2

The value of d=2

Now we find out YZ using d=2

YZ=9d-2\\YZ=9(2)-2\\YZ=16

The value of YZ is 16
