find the value of x
Answer:
24°
Step-by-step explanation:
[tex]180 - (94 + 41) = 45[/tex]
[tex]180 - (111 + 45) = 24[/tex]
Help on this too pls
Step-by-step explanation:
Half of 40 is 20 and luckily they already gave us how much she would earn if she worked 20 hours.
So all we have to do is multiply the amount of money she earned when she worked 20 hours by 2 to see how much she earned when she worked 40 hours.
20 hours:165 dollars or 20:165
20 x 2= 40 and 165x2=330
So if Monique worked 40 hours she would earn $330.
(((3x)^(-1)-(4y)^(-1)))/((9x)^(-2)-(16y)^(-2))..
Simplified: xy/3y+4x
factored: 1/(3/x)+(4/y)
How does f(t) = 3 x 9 ^t change over the interval from t = 6 to t = 7?
Answer:
sorry got it wrong on the first try. Increases by 800% is the answer
Step-by-step explanation:
put x = 3 into f(x)=6x and you get f(x) = 18
Put x = 4 into f(x) and you get f(x) = 24
Subtract those two. 24 - 18 = 6
Also, f(x) = 6x it will always be 6 away from the next x you put into the equasion.
Or better said, it will be 6 more from 6x, because you are changing the x to X+1, hence,
6(x+1) = 6x + 6.
+6, it increases.

Answer:
(5x+4)x(5x+4)
Step-by-step explanation:
Factor using quadratic formula (or AC method if you prefer)
formula: [-b ±[tex]\sqrt{b^{2} -4ac}[/tex]]/2a
Plug in
[-40 ± [tex]\sqrt{1600-1600}[/tex]]/2(25)
-40/50
x=-4/5
But since we need to find the factored form we put everything on one side.
5x+4=0
Since there is no ±, that means that there is perfect square. Both sides would be 5x+4

Without writing the equation 21x^2 - 84x + 12y^2 - 24y = -6 in the standard form, state whether the graph of this equation is a
parabola, circle, ellipse, or hyperbola.
a. parabola
c. hyperbola
b. ellipse
d. circle
Answer:
b. ellipse
Step-by-step explanation:
The squared terms have the same sign and different coefficients. That means the equation describes an ellipse.
__
Additional comment
both variables are highest degree 2:
coefficients have the same sign and magnitude: circle
coefficients have the same sign and different magnitude: ellipse
coefficients have different signs: hyperbola*
only one variable has highest degree 2:
parabola
____
* If the equation can be factored to a product of linear terms that is zero, then the equation is of two intersecting lines. This is a degenerate case of the hyperbola in which the major axis is zero: the two vertices are the same point.

Answer:
504 [tex]in^{2}[/tex]
Step-by-step explanation:
area of the square -> 14*14 = 196
area of one of the triangles -> 1/2(11*14) = 77
area of all four triangles -> 77 * 4 = 308
surface area = area of square + area of four triangles
= 196 + 308
= 504
Marie noticed that she was eating 2100 calories per day she began a diet and limited herself to 1300 calories per day. What is the percent of decrease? Round to the nearest percent.
Answer:
decrease of 38% (to nearest percent)
Step-by-step explanation:
Percent change = [ (difference between final and initial value) ÷ initial value] x 100
⇒ percent change = [(2100 - 1300) ÷ 2100] × 100 = 38% (to nearest percent)

The solution to the given equation is [tex]x=-2[/tex] .
What are equations?Equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign.
We have,
[tex]2ln(x+3)=0[/tex]
Now,
Divide the above equation by [tex]2[/tex],
We get,
[tex]ln(x+3)=0[/tex]
Using the properties of logarithms,
We get,
[tex](x+3)=1[/tex] [tex](Because\ ln(0)=1)[/tex]
[tex]x=-3+1[/tex]
[tex]x=-2[/tex]

Over the weekend, Cedrick drove 45 1/4 miles. He used 2 1/2 gallons of gasoline. What is the unit rate for miles per gallon?
1 [tex] \frac{5}{8}\\ [/tex]
Step-by-step explanation:
To find unit rates, divide the number in the numerator of the rate by the number in the denominator of the rate. A car traveled 344 miles on 16 gallons of gasoline. To find the miles per gallon (unit rate), divide the numerator of the rate by the denominator of the rate. 344/16 = 21.5 miles / gallon is the rate.

Diane is participating in a 6-day cross-country biking challenge. She biked for 54 , 50 , 47 , 55 , and 60 miles on the first five days. How many miles does she need to bike on the last day so that her average (mean) is 53 miles per day?
The formula for mean/average is m = sum of the terms/number of the terms. Basically, you add all the numbers provided and divide it by how many of them.
So our terms are 48, 54, 51, 69, 64. We are missing the last term, which the problem needs us to find, in order to meet the requirement of the average 58 miles per days, which is m.
Let's call the last term x.
m = sum of the terms/number of the terms
58 = (48 + 54 + 51 + 69 + 64 + x)/6
We need to work backward the formula to find x.
Because (48 + 54 + 51 + 69 + 64 + x) divided by 6 gives us the m, which is 58, we will multiply 58 by 6 to give us the sum of (48 + 54 + 51 + 69 + 64 + x)
58 * 6 = 348
So 348 is the sum of 48 + 54 + 51 + 69 + 64 + x. Let make it into an equation:
48 + 54 + 51 + 69 + 64 + x = 348. Now, simplify it by adding all the values except x.
286 + x = 348. Now what is left is to take 348 minus 286, which gives us 62.
Let's check by plugging 62 as x into the mean formula.
(48 + 54 + 51 + 69 + 64 + 62)/6 = m = 58
Hope this helps!

Answer:
A
Step-by-step explanation:
The initial amount is 64, so that would be the y-intercept.
Each piece of wood, x, is [tex]6\frac{1}{4}[/tex] inches long, so x pieces would be [tex]6\frac{1}{4}x[/tex] pieces long.
Because you're subtracting the length of the pieces from the total length, you would subtract [tex]6\frac{1}{4}x[/tex] from 64.
