This is a isosceles triangle. As it is a triangle we can apply sum theory. we have to take the sum of given unknown polynomials as 180° .Then by solving it we can find the value of x.
Solution:-Given angles
(6x+10°)(x+17°)(4x-34)°According to sum theory
[tex]{\boxed{\sf The \:sum\:of\:angles=180°}}[/tex]
Substitute the values[tex]\qquad \quad{:}\longmapsto\tt (6x+10)+(x+17)+(4x-34)=180 [/tex]
Remove brackets[tex]\qquad \quad{:}\longmapsto\tt 6x+10+x+17+4x-34=180 [/tex]
Together like polynomials and constants[tex]\qquad \quad{:}\longmapsto\tt 6x+x+4x+10+17-34=180 [/tex]
[tex]\qquad \quad{:}\longmapsto\tt 11x-7=180 [/tex]
Interchange sides[tex]\qquad \quad{:}\longmapsto\tt 11x=180+7 [/tex]

When the U.S. government needed 10,000 rifles for the army, Eli Whitney applied for the contract. He took several guns, dismantled them, put the pieces in a box, and shook it. He then randomly selected the pieces he needed, assembled on rifle, and fired it. What did he demonstrate
Answer:
interchangeable parts.

Eli Whitney here demonstrates interchangeable parts.He took several guns, dismantled them, put the pieces in a box, and shook it. He then randomly selected the pieces he needed, assembled on rifle, and fired it. popularized in America when Eli Whitney used them to assemble muskets in the first years of the 19th century, allowed comparatively unskilled workers to manufacture vast quantities of arms rapidly and at lower expense, and made repair and replacement of parts exponentially simpler.
if a circle has a circumference of 6/5 pi centimeters how long is its radius in centimeters
Answer:
r=3/5 centimeters
Step-by-step explanation:
C=(2)(pi)(r), where C= circumference and r=radius
6/5*pi=2*pi*r
divide both sides by 2pi
r=6/5pi*1/2pi
r=3/5

Step-by-step explanation:
If c=g-4f, find trinomial that represents C when F=2x^2-5 and G=5x^2+x-3
Answer:
c = -3x² + x + 17
Step-by-step explanation:
c = g - 4f
f = 2x² - 5
g = 5x² + x - 3
c = (5x² + x - 3) - 4(2x² - 5)
c = 5x² + x - 3 - 8x² + 20
c = -3x² + x + 17

On a certain hot summer's 439 day, people used the public swimming pool. The daily prices are $1.75 for children and $2.50 for adults. The receipts for admission totaled $1021.00 How many children and how many adults swam at the public pool that day?
Answer:102 children and 337 adults swam at the publice pool that da
Step-by-step explanation:
let the number of children be x
and
the number of adults be y
such that the total number of people who came to use the public swimming pool be expressed as
x + y = 439----- Equation 1
and price for swimming be expressed as
1.75x + 2.50y =1021----- Equation 2
Step 2
x + y = 439----- Equation 1
1.75x + 2.50y =1021----- Equation 2
First make x the subject formulae and put in equation 2
x= 439-y
1.75 (430-y) + 2.50y = 1021
Solving gives
768.25-1.75y+2.50y=1021
2.50y-1.75y=1021-768.25
0.75y=252.75
y =252.75/0.75
y=337
To find x, put the value of y = 337 in equation 1
x+y= 439
x= 439-337
x=102
Therefore 102 children and 337 adults swam at the public pool that day

Step-by-step explanation:
Sal places $500 in a retirement account that offers a return of 3.5% compounded annually . He will not deposit or withdraw any money from the account . Which function represents f(t) , the amount of money in the account after years a f(t) = 500 * (0.035) ^ t c. F(t) = 500 + 0.035t f(t) = 500 * (1.035) ^ t d. F(t) = 500 + 1.035t
Answer:
f(t) = 500 * (1.035) ^ t
Step-by-step explanation:
A = p(1 + r/n)^nt
Where
A = future value = ?
P = principal = $500
r = interest rate = 3.5% = 0.035
n = number of periods = 1
t = number of years = t
A = p(1 + r/n)^nt
= 500(1 + 0.035/1)^1*t
= 500(1 + 0.035) ^t
= 500( 1.035)^t
= 500 * (1.035)^t
f(t) = 500 * (1.035) ^ t

Sarah says that 26 ÷ 8 equals 14 ÷ 4 because both are “3 R2.” Show her mistake using decimal division. What is 26 ÷ 8? Give your answer in decimals. 26 ÷ 8 =___. Please helpppppp
Answer: 3.25
Step-by-step explanation:
Sarah made a.mistaje when she was reducing 26 ÷ 8. It should be noted that 2 is a common factor to 26 and 8. Therefore 26÷2 = 13 and not 14 that Sarah wrote. Sarah should have written 13 ÷ 4 and not 14 ÷ 4.
26 ÷ 8 in decimal will give us 3.25
Bertha deposited $1000 into a retirement account when she was 18. How much will Bertha have in this account after 50 years at a yearly simple interest rate of 7.5%?
Answer:
$4750
Step-by-step explanation:
Simple interest is the interest calculated on the principal at a given rate for a time period.
The simple interest formula is given as,
SI = P x R x T / 100
P = principal
R = rate
T = time
Amount = SI + P
The amount Bertha will have in his account after 50 years is $4750.
What is simple interest?Simple interest is the interest calculated on the principal at a given rate for a time period.
The simple interest formula is given as,
SI = P x R x T / 100
P = principal
R = rate
T = time
We have,
P = $1000
T = 50
R = 7.5%
A = SI + P
SI = (1000 x 7.5 x 50) / 100
SI = 1000 X 7.5 X 50 / 1000
SI = $3750
A = SI + P
A = 3750 + 1000
A = $4750
Thus,
The amount Bertha will have in his account after 50 years is $4750.

Circle theorems please help
Answer:
n = 28°
Step-by-step explanation:
The angle at the centre is twice the angle on the circle subtended on the same arc.
Also angles subtended on the same arc are congruent , thus
m = n
Then
35 + m = [tex]\frac{1}{2}[/tex] (98 + n ) ← multiply both sides by 2 to clear the fraction
70 + 2m = 98 + n , but since m = n, then
70 + 2m = 98 + m ( subtract m from both sides )
70 + m = 98 ( subtract 70 from both sides )
m = 14 and n = 28

The measure of angle JLM is 140°. The measure of angle JKL is 75.
What is the measure of angle KJL
Enter your answer in the box.
Answer:
KJL is 65 degrees
Step-by-step explanation:
If JLM is 140 deg. JLK is 40 deg the two angles on transverse line must equal 180 total.
JKL being 75 degf, sum that with JLK of 40= 115 deg
180-115= 65 deg Sum of interior angles on a triangle add up to 180 deg.
At least that is how I remember it, you can also graph it and check it out.
