11x-1+20x-3=151 (the exterior angle of an triangle is equal to the sum of two opposite interior angles)
31x-4=151
31x=151+4
31x=155
x=155/31
x=5°
11)

Answer:
W = 10 cm
Step-by-step explanation:
Area of a Triangle and a Rectangle
The area of a triangle of base B and height H is:
[tex]\displaystyle A_t=\frac{BH}{2}[/tex]
The area of a rectangle of width W and length L is:
[tex]A_r=WL[/tex]
We are given the base of the triangle B=6 cm and the height H=8 cm, thus the area is:
[tex]\displaystyle A_t=\frac{6*8}{2}= 24\ cm^2[/tex]
The area of the rectangle is 5 times the area of the triangle, thus:
[tex]A_r=5*24\ cm^2=120\ cm^2[/tex]
If we know the area of the rectangle and its length, we can find the width by solving for W:
[tex]\displaystyle W=\frac{A_r}{L}[/tex]
The rectangle has a length of L=12 cm, thus:
[tex]\displaystyle W=\frac{120}{12}=10\ cm[/tex]
W = 10 cm

Explain it too and what specific polynomial subject.
Answer:
C
Step-by-step explanation:
Expand the factors and compare the coefficients of like terms.
Given
(mx + 2)(3x - 5) ← expand using FOIL
= 3mx² - 5mx + 6x - 10
Compare to 12x² - 14x - 10
For the 2 to be equal, then the coefficients of like terms must be equal.
Compare coefficients of x² terms
3m = 12 ( divide both sides by 3 )
m = 4 → C

Aubree invested $4,400 in an account paying an interest rate of 2.4% compounded
quarterly. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest tenth of a year, for the value of the account to reach $6,880?
Answer:
We conclude that the time required to get a total amount of $6,880.00 from compound interest on a principal of $ 4,400.00 at an interest rate of 2.4% per year and compounded 4 times per year is 18 years and 8 months.
Step-by-step explanation:
We know the formula
[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}[/tex]
where
A denotes the Accrued Amount (principal + interest) P denotes the Principal Amount r denoted the Annual Interest Rate t denotes the Time Period in yearsn denotes the number of compounding periods per unit tGiven
Total amount A = $6,880
Principle amount P = $4,400
Interest Rate r = 2.4% = 0.024 per year
Compounded quarterly = n = 4
Thus, the time period can be fetched using the simplified-derived equation suchs as:
t = ln(A/P) / n[ln(1 + r/n)]
substituting the values
t = ln(6,880.00/4,400.00) / ( 4 × [ln(1 + 0.006/4)] )
t = 18.8 years
Therefore, we conclude that the time required to get a total amount of $6,880.00 from compound interest on a principal of $ 4,400.00 at an interest rate of 2.4% per year and compounded 4 times per year is 18 years and 8 months.

can someone help me plz .. Use these lengths to find cos B, tan B, and sin B.
Answer:
cos B = [tex]\frac{7}{25}[/tex]
tan B = [tex]\frac{24}{7}[/tex]
sin B = [tex]\frac{24}{25}[/tex]
Step-by-step explanation:
In the right triangle, there are three sides and 2 acute angles
Hypotenuse ⇒ the opposite side of the right angleLeg1 and Leg 2 ⇒ the sides of the right angleThe trigonometry functions of one of the acute angles Ф are
sin Ф = opposite leg/hypotenusecos Ф = adjacent leg/hypotenusetan Ф = opposite leg/adjacent legIn Δ ACB
∵ ∠C is the right angle
∴ AB is the hypotenuse
∵ AC is the opposite side of ∠B ⇒ leg1
∵ CB is the adjacent side of ∠B ⇒ leg2
→ By using the ratios above
∴ cos B = [tex]\frac{CB}{AB}[/tex] , tan B = [tex]\frac{AC}{CB}[/tex] , sin B = [tex]\frac{AC}{AB}[/tex]
∵ CB = 7, AB = 25, AC = 24
∴ cos B = [tex]\frac{7}{25}[/tex]
∴ tan B = [tex]\frac{24}{7}[/tex]
∴ sin B = [tex]\frac{24}{25}[/tex]

Answer:
160-20=140. 140/4=$35.
is it one to one or onto? why?
Answer:
Step-by-step explanation:
Given quadratic function is,
f(x) = -x² - x + 1
Range of the function has been defined as (-∞, [tex]\frac{5}{4}[/tex] ]
Domain of the function is a set of all real numbers.
From the graph of this function,
At x = -3 and x = 2, value of y = -5
But for one to one functions, every x value should map to a different value of y.
Therefore, function is not one to one.
Since, every value of domain (x-value) maps the range (y-value) in the given range (-∞, [tex]\frac{5}{4}[/tex] ], function will be defined as onto.
Therefore, this function is ONTO, but NOT ONE TO ONE.
Jason was hired to mow a lawn that covers an area of 2 3/4 acres. It took him 4 1/8 hours to complete the job. What was his unit rate in hours per acre?
In this activity, you will multiply the numerator in a complex fraction by the reciprocal of the denominator to calculate a unit rate involving fractions. Answer the questions below to calculate Jason’s unit rate as he mowed.
Answer:
2 3/4 = 11/4
4 1/8 = 33/8
11/4 / 33/8 = 11/4 * 8/33 = 88/132 = 2/3
He mowed 2/3 of an acre per hour

You decide to invest $997.90 at an interest rate of 17% l, how long will it take to triple your money? Round to the nearest whole number.
Answer:
Approximately 18 years
Step-by-step explanation:
Triple: 997.90*3. which is 2993.7
997.90*0.17*x=2993.7
(x is time)
169.643x=2993.7
x=2993.7/169.643
x= approximately 17.64....... years/
18 years.

Answer:
B
Step-by-step explanation:
x + y = 90
Your x and y will give you a sum of 90
y= 4x + 6
Your y will be 6+ more then 4 TIMES x
therefore you would do 4 times x plus 6 equals y
