Answer:

[tex]\frac{16}{5}[/tex] or [tex]3.2[/tex]

Step-by-step explanation:

The given triangles are similar, meaning that their corresponding sides are proportional.

The length of DC (I think its D) is 15 and the length of WZ is 3. ZY is in the same place as CE (16). Make a proportional relationship where Δ→Δ:

[tex]\frac{large}{small} =\frac{large}{small}[/tex]

[tex]\frac{DC}{WZ}=\frac{CE}{ZY}[/tex]

Insert the known values:

[tex]\frac{15}{3}=\frac{16}{x}[/tex]

x is the value of ZY. Solve by cross multiplying:

[tex]15(x)=3(16)\\\\15x=48[/tex]

Divide both sides by 15:

[tex]\frac{15x}{15} =\frac{48}{15} \\\\x=3.2[/tex]

ZY is 3.2.

✔️<1 can be named in two ways using letters, with the middle letter being the letter of the vertex of the angle. Thus is can be named as:

[tex] \angle ADB [/tex] or as [tex] \angle BDA [/tex]

✔️It is unclear to name <1 as <D because <2 can equally be named as <2 since both angles share a common point or vertex D.

Answer:

A. 3 bags of popcorn

F. $12.25

G. 6 bags of popcorn

Heya, I hope this helped you! If you divide 3.5 by 2, it is $1.75 for each bag of popcorn. I hope this helped! <3

Answer: A. Murderer bought three bags

F. $21.00

G. 6 bags

Step-by-step explanation:

divide 3.50 by 2 gives you 1.75 and 1.75+3.50= 5.25 which is the total spent.

1.75 x 6 is equal to 10.50 and 12.82-2.32= 10.50

Answer:

Move it to the [tex]\frac{-1}{2}[/tex] point

Step-by-step explanation:

Two minus makes one plus.

D = -[tex]\frac{1}{2}[/tex]

-(-D) = +(-[tex]\frac{1}{2}[/tex])

       = -[tex]\frac{1}{2}[/tex]

       = [tex]\frac{-1}{2}[/tex]

Answer:

Step-by-step explanation:

nine thousand five hundred sixty two thousand four hundred thirteen.

The mean of the data is 6.25. Then the mean absolute deviation of the data will be 1.75.

It is the average distance between each data point and the mean. Then the mean absolute deviation is given as,

[tex]\rm MAD = \dfrac{\Sigma _{i = 1}^n|x_i - \mu|}{n}[/tex]

The data is given below.

6, 2, 8, 4, 8, 6, 8, 8

The mean of the data will be given as,

μ = (6 + 2 + 8 + 4 + 8 + 6 + 8 + 8) / 7

μ = 50/8

μ = 6.25

Then the mean absolute deviation of the data will be given as,

MAD = (|6 - 6.25| + |2 - 6.25| + |8 - 6.25| + .... + |8 - 6.25|) / 8

MAD = (0.25 + 4.25 + 1.75 + 2.25 + 1.75 + 0.25 + 1.75 + 1.75) / 8

MAD = 14 / 8

MAD = 1.75

5) The height of a rocket after it is launched

For this case, what you should do is remember the kinematics expressions where we have:

a

v = a * t + vo

y = a * t ^ 2 + vo * t + i

Where,

a: acceleration

v: speed

y: vertical position

t: time

vo: initial speed

yo: initial position

We observe that the expression for the given position is given by a quadratic expression.

Answer:

6x^3 - 16x^2 - 14x + 24

Step-by-step explanation:

The distance of Jamal's house to the park is 12 miles.

The distance from Loretta's house to a park is 43 miles.

Her friend Jamal lives along this same highway between Loretta's house and the park.

The distance from Loretta's house to Jamal's house is 31 miles.

The situations forms a straight line segment.

Therefore,

Loretta's house distance to the park = 43 miles

Lorretta's house distance to Jamal's house = 31 miles

Therefore,

distance of Jamal's' house to the park =  43 - 31

distance of Jamal's' house to the park = 12 miles

Step-by-step explanation:

Answer:

B) 1p - 0.4p

Step-by-step explanation:

40% to a decimal is 0.4, so that immediately marks "A" and "C" wrong.

Now what you're trying to find is the expression itself, so you want to first look for keywords, 'cause sometimes they can just give away the answer.

"A" says you're multiplying (a variable beside a number means to multiply)

"B" says you're subtracting 1p (1 x p) and 0.4p (0.4 x p)

"D" says you're adding 1p (1 x p) and 0.4p (0.4 x p)

So, now you look over the question.

Really you can mark "A" wrong. Now it's just between "B" and "D."

When you use percentages and an item, you're taking it OFF the price. So, the answer is B.

Given:

Student ticket price = $7

A group of 4 students and 3 adults paid $64  in all for movie tickets.

To find:

Each of the adult ticket cost.

Solution:

Let x be the cost of each adult ticket.

Then, cost of 3 adult tickets = 3x.

Cost of 1 student ticket = $7

Cost of 4 student ticket = $7(4)

According to the question,

[tex]7(4)+3x=64[/tex]

[tex]28+3x=64[/tex]

[tex]3x=64-28[/tex]

[tex]3x=36[/tex]

Divide both sides by 3.

[tex]x=12[/tex]

Therefore, the cost of each adult ticket is $12.

Answer:

The simple interest is $58.5

Step-by-step explanation:

Mathematically;

Simple interest = PRT/100

where p is principal = $300

R is rate = 6.5%

T is time = 3 years

Substituting these values in the simple interest equation, we have that;

S.I = (300 * 6.5 * 3)/100 = $58.5

Answer:

[tex](f+g)(x)=x^2-4x-21[/tex]

Step-by-step explanation:

We are given:

[tex]f(x)=x^2-5x-14\text{ and } g(x)=x-7[/tex]

And we want to find:

[tex](f+g)(x)[/tex]

This is equivalent to:

[tex]=f(x)+g(x)[/tex]

Therefore, by substitution:

[tex]=(x^2-5x-14)+(x-7)[/tex]

Rearranging gives:

[tex]=(x^2)+(-5x+x)+(-14-7)[/tex]

Combine like terms:

[tex]=x^2-4x-21[/tex]
