Question 2 : There are 40 students in Mrs. Jackson's class, and
1/4 of the class has their own cell phone. Of this group of
students, 1/2 of them are allowed to use social media. How many
of the students have a cell phone and can use social media?

Answers

Answer:

5

Step-by-step explanation:

First find the number that have their own cell phone

1/4 * 40 = 10

There are 10 students with their own cell phone

1/2  of the 10 can use social media

1/2 * 10  =5

5 have their own cell phone and can use social media

Answer: 10 students have a cell phone and only 5 of them can use social media

Step-by-step explanation: We see there are 40 students in total and 1/4 OF the class have their own cell phone. The OF means multiplacation so we do 40 X 1/4 which is 10 students who have their cellphone. We then again see 1/2 OF the 10 students can use social media meaning we do 10 X 1/2 which is equal to 5 students out of the 10 can use social media.

Answers

Answer:

Duration = 6 hours

Step-by-step explanation:

Given

[tex]Regina: 6.50h + 16[/tex]

[tex]Phil: 3(2.5h + 5)[/tex]

[tex]Joseph: 7.50h + 10[/tex]

Required

When will Ragina and Joseph earn equal amounts

To solve this:

[tex]Regina = Joseph[/tex] must be true

This gives:

[tex]6.50h + 16 = 7.50h + 10[/tex]

Collect Like Terms

[tex]7.50h - 6.50h = 16 - 10[/tex]

[tex]h = 6[/tex]

Hence, number of hours is 6

The perimeter of a rhombus is 40 cm and the length of one of its diagonals is 12 cm then the length of the other diagonal is

Answers

Answer:

16 cms.

Step-by-step explanation:

The length of each side = 40 / 4 = 10 cm (as the 4 sides of a rhombus are congruent).

If we draw the other diagonal we form 4 right angled triangles (another property of the rhombus - diagonals bisect each other at tight angles. ).

The side of the rhombus is the hypotenuse of the right triangle.

So if we consider one triangle:

10^2 = 6^2 + x^2   where x is half the length of the other diagonal.

x^2 = 10^2 - 6^2

x^2 = 100 - 36 = 64

x = 8 cm.

So the diagonal is 16 cms long.

Solution: cot(52°)

Step-by-step explanation:

Remember that the cofunction of angle theta say, is the trigonometric complement of the angle. It represents the relationship between trigonometric functions. In this case you can use the formula:

tan(θ) = cot(90° - θ)

If we plug in '38 degrees' in replacement of 'theta' we can solve for tan(38) in terms of cot. Let's see what our solution is:

tan(38°) = cot(90° - 38°),

tan(38°) = cot(52°)

Therefore the cofunction with the same value as tan(38°) would be cot(52°). Remember this is only one example of it's 'cofunction.'

Answer:

cot(52)

Step-by-step explanation:

cofunction of tan (38)

The cofunction of and angle Ф is the trigonometric complement of an angle.

it shows the relationship between trigonometric  functions as:

list the cofunction formula for tan

tan(Ф) = cot(90° - Ф)

plugin Ф = 38 into the formula:

tan (38) = cot(cot(90° - 38)

tan(38 = cot(52)

f(x)
-----
g(x)

(4,__)

6/7
1
7/6

Answers

Answer: Choice A.  6/7

=======================================================

Explanation:

The given ordered pair is (4, ___) so we have x = 4 here.

We will plug this into f(x) and g(x) to get

f(4) = 6

g(4) = 7

So we have [tex]\frac{f(4)}{g(4)} = \frac{6}{7}[/tex]

-----------

If you're curious where f(4) = 6 came from, all we're doing is looking through the set of points

f = {(0, 1), (2, 4), (4, 6), (6, 8)}

to see which has 4 listed first as the x coordinate. That point is (4,6) so x = 4 leads to y = 6, ie, f(x) = 6 when x = 4. A similar situation happens with g(x) as well.

Set V is all the unique three-digit numbers using the digits 1, 2, 3, 4, and 5. Which set would be considered a subset of set V? Set W is all the unique three-digit numbers using the digits 1, 3, and 5. Set X is all the unique three-digit numbers using the digits 2, 4, and 6. Set Y is all the unique three-digit numbers using the digits 0, 2, and 4. Set Z is all the unique three-digit numbers using the digits 3, 5, and 7.

Answers

Answer: Choice A) Set W is all the unique three-digit numbers using the digits 1, 3, and 5

==========================================================

Explanation:

The original set uses the digits {1,2,3,4,5}. We can only use those digits. Nothing else. So that means we can't use 0, 2, 4, 6, or 7. This rules out choices B through D.

Only choice A is left. This answer choice involves 1,3 and 5 which is the correct subset of digits to use.

--------

Put another way, if set B was a subset of set A, then everything in B must also be found in A. Having B = {2,4,6} and A = {1,2,3,4,5} shows B is not a subset of A. We see a counter example has 6 in B, but not in set A.

This allows us to rule out choice B. Similar ideas apply to the answer choices C and D as well.

a sidewalk is 5ft wide, 6in deep, and 220 ft long. how many cubic yards of concrete are needed to fill it?

Answers

Answer:

1100/54 yds

Step-by-step explanation:

First convert inches and feet to yards

[3 ft = 1 yd, 12in = 1yd]

5ft = 1 2/3 yds

6in = 1/6 yds

220ft = 73 1/3 yds

Now use the volume formula,

b*w*h = A

[1 2/3] * [1/6] * [73 1/3]

= [5/3] * [1/6] * [220/3]

= [5/18] * [220/3]

= 1100/54 yds
