Answer:
•SEE BELOW•Let the diameter be represented as x.
Let the diameter be represented as x.Based on the secant-tangent theorem, the following equation representing the relationship between the segments would be:
segments would be:(14 + x)(14) = 25^2
segments would be:(14 + x)(14) = 25^2196 + 14x = 625
segments would be:(14 + x)(14) = 25^2196 + 14x = 625Subtract 196 from each side
14x = 625 - 196
14x = 625 - 19614x = 429
Divide both sides by 14
Divide both sides by 14x = 429/14
Divide both sides by 14x = 429/14x = 30.6
Divide both sides by 14x = 429/14x = 30.6Diameter = 30.6

Step-by-step explanation:
Given:
Helen's age = N year old
Helen's brother = One year older than helen
To find:
a. Write n algebraic expression for the age of Helen’s brother
b. Find her brother’s age if Helen is age 12
C. Find her brothers age If Helen is x years old
Solution:
A)algebraic expression for the age of Helen’s brother = Helen’s age + 1 = N+1
[tex]\fbox{Age of Helen’s brother = N+1}[/tex]
B) if helen is 12 year old then, N = 12
substituting the value of N in above equation,
Age of Helen’s brother = N+1 = 12+1 = 13 y/o
[tex]\fbox{Age of Helen’s brother = \: 13 \: year \: old}[/tex]
C) if helen is x year old then, N = x

The dimensions of the parallelogram to the nearest hundredth of an inch are 6.54 in and 3.06 in.
What are the dimensions of the parallelogram?Trigonometry would be used to determine the base and the length of the parallelogram.
Base: cos 40 = adjacent /hypotenuse
0,7660 = adjacent / 4
adjacent = 4 x 0.7660 = 3.06 in
Length = area / base
20 / 3.06 = 6.54 in

Well has -55.00 in his account if he saves $2.50 his mom gives him lunch every day, how many days will it be until he has a balance of at least $0
Answer:
22 days
Step-by-step explanation:
55 divided by 2.5=22 days
Answer: 22 Days
Step-by-step explanation:
-55.00/2.50= -22
But since you can’t have a negative answer then you have to make it positive for your amount of days! So it would take that person 22 days to have 0 in his account!

y = 0
Answer:
x= -4 and y=2
Step-by-step explanation:
-3x+y=14 ...eqn 1
2x+3y= -2....eqn 2
from eqn 1
-3x+y=14
y=14+3x
substitute y=14+3x into eqn 2
2x+3(14+3x) = -2
2x+ 42+ 9x = -2
11x= -2-42
11x= -44
x = -4
substitute X = -4 into eqn 1 to get y
-3x+y=14
-3(-4) +y =14
12+y= 14
y= 14-12
y =2

Use the quadratic formula to solve the equation 2k(k+5)= -25
So, we need to solve the quadratic equation from quadratic formula as per the question, but before starting, let's first recall that, for any quadratic equation of the form ax² + bc + c = 0, the discriminant is given by D = b² - 4ac, and the value of x is given by :
[tex]{\boxed{\bf{x=\dfrac{-b\pm \sqrt{D}}{2a}}}}[/tex]Also, their are no real solutions of x i.e their are only imaginary values of x iff D < 0, equal and real roots iff D = 0 and real and distinct roots iff D > 0. So, let's convert the given equation to the standard form ax² + bx + c = 0 and then we will find the discriminant and then we will be solving for k ;
[tex]{:\implies \quad \sf 2k(k+5)=-25}[/tex]
[tex]{:\implies \quad \sf 2k^{2}+10k=-25}[/tex]
[tex]{:\implies \quad \sf 2k^{2}+10k+25=0}[/tex]
Now, on comparing this with the standard equation, we will get a = 2, b = 10 and c = 25, and then D = (10)² - 4 × 2 × 25 = 100 - 200 = - 100, now as D < 0, so their will be imaginary values of k, so now solving for k will yield by using the Quadratic Formula ;
[tex]{:\implies \quad \sf k=\dfrac{-10\pm \sqrt{-100}}{2\times 2}}[/tex]
[tex]{:\implies \quad \sf k=\dfrac{-10\pm 10\iota}{2\times 2}}[/tex]
[tex]{:\implies \quad \sf k=\dfrac{2(-5\pm 5\iota)}{2\times 2}=\dfrac{-5\pm 5\iota}{2}}[/tex]
[tex]{:\implies \quad \boxed{\bf{k=\dfrac{-5+5\iota}{2}\:\:,\:\: \dfrac{-5-5\iota}{2}}}}[/tex]

A map of utah has scale 1cm :30 mi the southern border is about 285 mi long how long is the border on the map
Answer:
9 1/2 inches
Step-by-step explanation:
The scale of a map is the ratio of map distance to represented distance. This can be used to write a proportion.
__
map distance/represented distance = 1 in/(30 mi) = x/(285 mi)
where x represents the map length of the southern border.
Multiplying by 285 mi, we have ...
x = (285 mi)(1 in)/(30 mi) = 9.5 in
The border is 9.5 inches on the map.

Corey deposits $3500 a bank which pays 3%
interest per year. How much money will John have in
his account after 10 years?
Answer:
35,000
Step-by-step explanation:
Answer:
Corey will have $4550.00 in is account after 10 years.
Step-by-step explanation:
This is simple interest. Here is the formula for simple interest.
[tex]A=P(1+r*t)[/tex]
A = Final Amount
P = Principal Amount
R = Interest Rate
T = Time
We are given values for P, r, and t. Lets solve for A.
To get 3 percent as a decimal divide it by 100. We get 0.03.
[tex]P=3500[/tex]
[tex]r=0.03[/tex]
[tex]t=10[/tex]
[tex]A=3500(1+0.03*10)[/tex]
[tex]A=3500(1+0.30)[/tex]
[tex]A=3500(1.30)[/tex]
[tex]A=4550[/tex]
A: x+90=180
B: 2x+90=180
C: x-90=180
D: Not enough info
Answer:
(B) 2x + 90 = 180 is an equation that could be used to find x.
Step-by-step explanation:
Observing at the triangle, we can see that..
- We are aware of two angel measurements, both of which are 45 degrees.
One triangle is exactly 180 degrees and if you add both 2 angel measurements from the triangles...
45 + 45 = 90 degrees
180 - 90 = 90 degrees
As a result, we know that x = 90. Now we find the equation. Lets look at equation B. ( 2x + 90 = 180 )
Step 1 : 90 should be subtracted from both sides.
2x + 90 − 90 = 180 − 90
2x = 90
Step 2 : Divide both sides by 2.
(When I use the symbol /, it signifies I'm dividing.)
2x/2 = 90/2
x = 45
Step 3: Examine your solution to see whether it is right.
2x + 90 = 180
2(45) + 90 = 180
90 + 90 = 180 ✓
This shows that 2x + 90 = 180 is an equation that could be used to find x.
Hope this helps! :D
