Answer:i think D but i would see what others say first
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.

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.

Answer/Step-by-step explanation:
✔️<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.

which of the followings are solutions that can be modeled with quadratic function? select all that apply
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.
The price of a movie ticket at the theater is $7 for students. The price is higher for adults. A group of 4 students and 3 adults paid $64 in all for movie tickets. How much does each adult ticket cost?
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.

Given that f(x) = x2 – 5x – 14 and g(x) = x – 7, find (f +g)(x) and
express the result in standard form.
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]
Find the amount of simple interest earned. Principal: $300. Annual interest rate: 6.5% Time: 3 years
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
