Answer:
Step-by-step explanation:
AX=9x+21, CX=14x+1, because AX=CX we can say
14x+1=9x+21, subtract 9x from both sides
5x+1=21, subtract 1 from both sides
5x=20. divide both sides by 5
x=4
Since CX is half of AC we can say
AC=2(14x+1)
AC=28x+2, and since x=4
AC=28(4)+2
AC=114

Bob and Sue are meeting on a stairway. Bob is at the top and Sue is at the bottom. There are 9 steps
from bottom to top. Bob can skip a step each time since he is going down, Sue will not skip any steps. On
which step will they meet.
Answer:
Bob is at the top, so he starts at step 9.
Sue is at the bottom, so she is at the step 0 (this is the floor, before stepping on step 1)
Sue climbs from one step on one step.
Then she if she climbs n times, she will be at the step number:
S(n) = 0 + 1*n
And Bob goes down by 2 steps each time, then after he goes down n times, his position will be:
B(n) = 9 - 2*n
We want to see when they meet, then we need to solve:
S(n) = B(n)
1*n = 9 - 2*n
1*n + 2*n = 9
3*n = 9
n = 9/3 = 3
n = 3.
This means that they meet a the step:
S(3) = 3*1 = 3
B(3) = 9 - 2*3 = 9 - 6 = 3
They meet at the third steep.
did u find an answer cause I need it lol
Leah has just inherited $12,000. She wants to invest the money so that she can increase the value of
her inheritance. What are some of the ways she can do this?
1. Leah wants to invest the $12,000 in an account that pays 4.5% annual interest.
a. Write equations for the amount A(t) that will be in the account after t years, if the interest is
compounded continuously, daily, and monthly. Then, find the amount after 10 years, rounded
to the nearest cent, for each method of compounding. Complete the table
When interset compounded continuously so the amount after 10 years the amount will be $18819.75, when n = 365 and t = 10 years amount will be $18819.22, when n = 12 and t = 10 years amount will be $18803.91.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We can calculate the compound interest using the below formula:
[tex]\rm A = P(1+\dfrac{r}{n})^{nt}[/tex]
Where A = Final amount
P = Principal amount
r = annual rate of interest
n = how many times interest is compounded per year
t = How long the money is deposited or borrowed (in years)
If the interest compounded continuously:
P = $12000, r = 4.5% = 0.045%
[tex]\rm A(t) =12000(e)^{0.045t}[/tex]
When t = 10 years, plug this value in the above expression and calculating, we get;
A(10) = $18819.75
When interest compounded daily:
[tex]\rm A(t) = 12000(1+\dfrac{0.045}{365})^{365t}[/tex]
Plug t = 10 years:
We get;
A(10) = $18819.22
Similarly,
If interest is compounded monthly:
n = 12 and t =10, we get:
A(10) = $18803.91
Thus, when interset compounded continuously so the amount after 10 years the amount will be $18819.75, when n = 365 and t = 10 years amount will be $18819.22, when n = 12 and t = 10 years amount will be $18803.91.

you move right 1 unit and left 3 units. you end at (-4,0). where did u start?
Answer:
(2,-4)
Step-by-step explanation:
you see (-4,0), then you do the opposite of what it says like it says right 1 unit. then you g left 1 unit. then it says left 3 units. so you go right 3, which results you starting at (2.-4)

In a team, the ratio of attackers : defenders is 11:7.
Given that there are 36 players in the squad, how many more attackers are there than defenders?
fast answers pls
Answer:
8 more attackers than defenders
Step-by-step explanation:
36÷18=2
2x11=22
2x7=14
Answer:
8
Step-by-step explanation:
sum the parts of the ratio, 11 + 7 = 18 parts
Divide the number of players by 18 to find the value of one part of the ratio
36 ÷ 18 = 2 players ← value of 1 part of the ratio, then
11 parts = 11 × 2 = 22 ← number of attackers
7 parts = 7 × 2 = 14 ← number of defenders
22 - 14 = 8
There are 8 more attackers than defenders

What is Kimberly's error?
A Kimberly did not find the inverse cosine of the value she calculated.
OB. Kimberly did not find the inverse sine of the value she calculated.
OC. Kimberly found the measure of angle N, not M.
D. Kimberly made a computational error.
E Kimberly did not apply the Law of Sines correctly
А
Answer:
The error is;
B. Kimberly did not find the inverse sine of the value she calculated
Step-by-step explanation:
The given parameters of the triangle ΔLMN are;
[tex]\overline {LN}[/tex] = 16
[tex]\overline {NM}[/tex] = 10
∠L = 33°
By sine rule, we have;
[tex]\dfrac{sin \ M}{16} = \dfrac{sin \ L}{10} = \dfrac{sin \ N}{\overline {LM}}[/tex]
Given that ∠L = 33°, we have;
[tex]\dfrac{sin \ M}{16} = \dfrac{sin \ 33^{\circ}}{10}[/tex]
Therefore, we have;
[tex]sin \ M = 16 \times \dfrac{sin \ 33^{\circ}}{10} \approx 0.8714[/tex]
sin M ≈ 0.8714
[tex]\therefore m \angle M = sin^{-1} \, (sin \ M)\approx sin^{-1} (0.8714) \approx 60.62^{\circ}[/tex]
Therefore, m∠M ≈ 60.62°
m∠M ≠ sin M ≈ 0.8714
Therefore;
Kimberly did not find the inverse sine (sin⁻¹) of the value she calculated
HELP FOR BOTH PLEASEE!!!!
Answer:
7) Option A
10) Option J
Step-by-step explanation:
7). From the graph attached,
Coordinates of S → (-5, 6)
Coordinates of U → (2, -6)
If the given points are reflected by the rule,
(x, y) → (-x, y)
[Change the sign of x - coordinates of S and U]
Coordinates of S' → (5, 6)
Coordinates of U' → (-2, -6)
Option A will be the answer.
10). Coordinates of the vertices of the ΔXYZ,
X → (6, 9)
Y → (9, 5)
Z → (4, 5)
If the vertices of this triangle are translated 3 units left and 4 units down,
Rule for the image points will be,
(x, y) → (x - 3, y - 4)
By this rule coordinates of the image points will be,
X(6, 9) → X'(3, 5)
Y(9, 5) → Y'(6, 1)
Z(4, 5) → Z'(1, 1)
Therefore, Option J will be the answer.

Write the equation of the line that passes through the points (-6, 4) and (-3,-2).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
y=-2x-8
Step-by-step explanation:
-2-4/-3-(-6)=-6/3=-2
y-4=-2(x-(-6))
y-4=-2(x+6)
y-4=-2x-12
y=-2x-12=4
y=-2x-8
The diameter of a circle is 24 meters. What is the circle's area? Use 3.14 for .
Answer:
To get the circumference, multiply the diameter by pi. You have the diameter in meters, and you were given an approximate value of pi. Multiply these 2 numbers, and get the circumference in meters.
Step-by-step explanation:
Answer:
144π or about 452.39
Step-by-step explanation:
Diameter = 24 meters
Radius = diameter/2 = 12 meters
Area of a circle = π*radius*radius = π*radius^2
Area = π*12^2 = 144π = 452.39
What is an equation of the line that passes through the points (4,-1) and (8,5)?
Answer:
y=3/2x-7
Step-by-step explanation:
the equation of the line for slope-intercept form is y=mx+b, where m is the slope and b is the y intercept.
we are given two points: (4,-1) and (8,5)
the equation for slope is (y2-y1)/(x2-x1)
label the points:
x1=4
y1=-1
x2=8
y2=5
now substitute into the equation:
m=(5--1)/(8-4)
m=6/4
m=3/2
the slope of the line is 3/2
here is our equation so far:
y=3/2x+b
we need to find b
since the equation will pass through the points, we can substitute either one into the equation to find b
let's use (4,-1) as an example
substitute into the equation
-1=3/2(4)+b
-1=6+b
-7=b
the y intercept is -7
so the equation is y=3/2x-7
hope this helps!

Given the figure as marked. What is x?
Answer:
6
Step-by-step explanation:
Using the similarity theorem f the triangle
(4+6)/x+9 = 4/x
10/x+9 = 4/x
Cross multiply
10x =4(x+9)
10x = 4x+36
10x-4x = 36
6x = 36
x = 6
Hence the value of x is 6
