Answer:

With the information provided, you can say that the total amount they spent together would be equal to the result of adding up the amount Emily spent plus the amount Lauren spent, which would be:

Amount Emily spent: $4.53

Amount Lauren spent: d

The expression is:

x=4.53+d, where:

x is the amount they spent together

d is the amount Lauren spent

What is trigonometry identity?

When trigonometric functions are used in an expression or equation, trigonometric Identities come in handy.

One of the trigonometry identity is  [tex]\cos2x=2\cos^{2} x-1[/tex].

What is the simplified expression for given expression?

In the given expression [tex]\cos6x[/tex] can be break as [tex]\cos(2\cdot3x)[/tex].

Now use the identity [tex]\cos2x=2\cos^{2} x-1[/tex] in the given expression.

[tex]1-\cos6x=1-2\cos^{2}{3x}+1[/tex]

[tex]=2(1-\cos^{2}{3x})[/tex]

Now use the identity [tex]1-\cos^{2}x=\sin^{2}x[/tex].

[tex]1-\cos6x=2\sin^{2}{3x}[/tex].

Therefore, the given expression is equivalent to [tex]2\sin^{2}{3x}[/tex].

Answer:

s = 17 inches

Step-by-step explanation:

Since this is a parallelogram, it has two sets of equal sides. We are given that one of the sides is 19 and the perimeter is 72. Therefore, \

72 = 2*s + 2*19

72 = 2*s + 38

34 = 2*s

s = 17

Answer:

17

Step-by-step explanation:

19 + 19 = 38

38 divided by 2 = 17

Add the given length to itself again because the other side is equal.

Which would be 38. Divide by 2 since there are two missing lengths that need to be solved (s). And your final answer is 17!

The expression is equivalent to the 1/4 (12 -3x) is 3 - 3/4x.

In mathematics, an expression is a phrase that has at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression's structure is as follows: (Number/variable, Math Operator, Number/variable) is an expression.

We have the Expression

1/4 (12 - 3x)

Now, using Distributive Property we get

a x (b+ c) = a x b + a x c

Then, 1/4 (12 - 3x)

= 1/4(12) - 1/4 (3x)

= 3 - 3/4x

Thus, the required expression is 3 - 3/4x.

Given:

Of the 50 flips, the coin landed on heads 30 times.

To find:

The experimental probability of flipping heads and compare it with the theoretical probability of flipping heads.

Solution:

We have,

Total number of trials = 50

Total number of heads = 30

The experimental probability of flipping heads is:

[tex]\text{Experimental probability}=\dfrac{\text{Total number of heads}}{\text{Total number of trials}}[/tex]

[tex]\text{Experimental probability}=\dfrac{30}{50}[/tex]

[tex]\text{Experimental probability}=\dfrac{3}{5}[/tex]

[tex]\text{Experimental probability}=0.6[/tex]

A coin has two sides one is heads and another is tails. So, the theoretical probability of flipping heads is:

[tex]\text{Theoretical probability}=\dfrac{1}{2}[/tex]

[tex]\text{Theoretical probability}=0.5[/tex]

Therefore, the experimental probability of flipping heads is 0.6 and the theoretical probability of flipping heads is 0.5. So, the experimental probability is greater than the theoretical probability of flipping heads.

Answer:

Options B, D and E

Step-by-step explanation:

Given equation is,

-4x + 5y - 12 = 8

-4x + 5y = 20

If a point given in the options lie on the line, point will satisfy the equation.

Option A.

For a point (5, 0),

-4(5) + 5(0) = 20

-20 = 20

False

Therefore, (5, 0) will not lie on the given line.

Option B

For (-2, 2.4)

-4(-2) + 5(2.4) = 20

8 + 12 = 20

20 = 20

True.

Therefore, (-2, 2.4) will lie on the given line

Option C

For (8, 5),

-4(8) + 5(5) = 20

-32 + 25 = 20

-7 = 20

False

Therefore, (8, 5) will not lie on the line.

Option D

For (10, 12)

-4(10) + 5(12) = 20

-40 + 60 = 20

20 = 20

True.

Therefore, (10, 12) will lie on the line.

Option E

For (0, 4)

-4(0) + 5(4) = 20

20 = 20

True.

Therefore, (0, 4) will lie on the line.

Options B, D and E are correct.

Answer:

D. A=34, B=28

Step-by-step explanation:

In the bulletin points, it says that seconds 3-5 are decreasing. That means that those heights can't be higher than second 2 (34). The only option that works is option D.

----------------------

Option A is incorrect because it starts with 35ft which is higher than second 2(34) so that is automatically wrong.

Option B is incorrect because it is increasing instead of decreasing.

Option C is incorrect for the same reason as Option A: it starts with 35ft.

Therefore, the only correct option is Option D.
