Plz help and ignore the equations below
Answer:
x = 8.5
Step-by-step explanation:
You have all three angles already, so it's easy: 90°, (4x - 8)°, (6x + 13)°
The sum of all angles is 180°
90 + (4x - 8) + (6x + 13) = 180
10x + 95 = 180
- 95 -95
10x = 85
x = 8.5

No solutions.
Step-by-step explanation:
22 does not equal 81, so therefore no solutions.
Tiana uses 1 3/5 oz of detergent for each full load of laundry. How many full loads of laundry can she do with 100 oz of detergent? Show your work.
Answer:
63 Full loads of laundry
Step-by-step explanation:
We have been told in the question that 1 3/5 oz or 8/5 oz of detergent is used for a full load of laundry.
So,
1 full load of laundry requires 8/5 oz of detergent
Then,
x full loads of laundry require 100 oz of detergent
100 = 8/5x
x = 100 * 5/8
x = 63 Full loads of laundry (to the nearest whole number)
What is the answer ??
UD = ?
Answer:
UD = 20
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
The square of the tangent is equal to the product of the external part and the entire secant, that is
12² = 7.2(7.2 + CD)
144 = 7.2² + 7.2CD
144 = 51.84 + 7.2CD ( subtract 51.84 from both sides )
92.16 = 7.2CD ( divide both sides by CD )
12.8 = CD
Thus
UD = UC + CD = 7.2 + 12.8 = 20

Question 2
A stereo that regularly costs $429.99 is on sale for 35% off. How much money will be discounted from the regular price? (Round to the nearest hundredth)
Your answer:
$35
$150.50
$394.99
Answer:
$150.50.
Step-by-step explanation:
The full price of the stereo is 429.99 which is 100%, the sale is 35%.
100 - 35 = 65%
100% = 429.99
1% = 429.99 ÷ 100 = 4.2999
35% =4.2999 x 35 = 150.4996
Estimated to 150.50
What are the solutions of each equation?
a. x2 + 4 = 4
b. x2 + 16 = 0
c. x2 − 49 = 0
Answer:
a. x=0
b x=-8
c x=49/2
Step-by-step explanation:
a. x2+4=4
subtract 4 from both sides
x2=0
multiply
2x=0
divide by 2
x=0
b x2 + 16 = 0
multiply
2x+16=0
subtract both sides by 16
2x=-16
divide by 2
x=-8
c x2 − 49 = 0
multiply
2x-49=0
add 49 to both sides
2x=49
divide both sides by 2
x=49/2
Answer:
a. X= 0
b. X= undefined or X=4i
c. X= + or - 7
Step-by-step explanation:
a. x² + 4 = 4
when 4 goes to the other side by negative sign it will cancel the other 4. at they equal in magnitude and opposite in sign.
then x² = 0 , where √x²=√0 , finally x=0
b. x² + 16 = 0
16 goes to other side by negative sign too
x² = -16 , where √x²=√-16 , finally x= undefined
due to the negative sign under thr square root.
at √-1 = i then x can be 4i
c. x² - 49 = 0
-49 go to the other side by positive sign
x² = 49 , where √x² = √49 , finally x= + or - 7
where negative sign is neglected at even power

(-7)²=(7)²
7z2−38z+15 Select the factors of this quadratic expression.
Answer:
(7z-3)(z-5)
Step-by-step explanation:
7z^2-38z+15
(7z-3)(z-5)
Answer:
(z - 5)(7z - 3)
Step-by-step explanation:
Given
7z² - 38z + 15
Consider the product of the factors of the coefficient of the z² term and the constant term which sum to give the coefficient of the z- term
product = 7 × 15 = 105 and sum = - 38
The factors are - 35 and - 3
Use these factors to split the z- term
7z² - 35z - 3z + 15 ( factor the first/second and third/fourth terms )
= 7z(z - 5) - 3(z - 5) ← factor out (z - 5) from each term
= (z - 5)(7z - 3) ← in factored form

plz answer only if correct.. i tried this problem many times and i keep getting the same answer..
Answer:
39
____________________________________________
Step-by-step explanation:
Since you want to find the variable x all you have to do is simple subtraction.
The two numbers (61 and 22). Subtract those numbers and you get 39. Now it wants you to round to the jearest hundredth but there is no hundreds place so we can round to the nearest tenth. Which would be 30! Hope it helped... :)!

Answer: 8y^6x^6
Step-by-step explanation:
Volume = l*w*h so multiply all the variable by multiplying the numbers and adding the exponents so
2y^2*4x^4y=8y^3x^4
then 8y^3x^4*x^2y^3=8y^6x^6
The image of the point (1, -3)(1,−3) under a translation is (-4, -2)(−4,−2). Find the coordinates of the image of the point (-3, 7)(−3,7) under the same translation.
Answer:
The new points under the translation are (-8,8) and (-8,8)
Step-by-step explanation:
The method is actually quite simple and only involves basic arithmetic. The first step is to identify the translations occurring to each coordinate. If we recall that an ordered pair is (x,y), we can assign the translations to each value. Let's take the first point (1, -3) to start. 1 is our x and -3 is our y. If we then look at the translated point we can see that the x value there is -4. Then we can simply subtract the new x value, -4, from the first one, 1, and get 5. 5 is the number that we have to subtract from the next coordinate set to get the translated set. This gets us the first value of the second point -8 which we got by subtracting our 5 from the -3 in the x. Next, we can do the y value. The process is identical. Subtract the new from the old, -3-(-2)=-1. We then simply subtract the negative one (or just add one) from the y value of the other set. This gives us a value of 8, 7-(-1)=8. Then compound the two together putting x first then y and there you have it! Happy to help, Mw

The CEO of a cell-phone company has recently noticed a 26% sales decrease in the month of July compared to June. Let n represent June’s sales. If y represents July’s sales, which equation can be used to determine the sales in July?
Answer:
y = n - 0.26n
y = 0.74n
Step-by-step explanation:
The equation that can be used to express the function above is given an Exponential Decrease function
Where:
y = a(1 - r)^t
Where
y = July sales
a = n = June sales
r = rate of decrease = 26% = 0.26
t = time in months = June to July = 1 month
t = 1
Hence, our equation =
y = n( 1 - 0.26)¹
y = n(1 - 0.26)
y = n - 0.26n
y = 0.74n
The equation that can be used to determine the sales in July is given as:
y = n - 0.26n
y = 0.74n
