if 50 percent of number is 26 what is 75 percent of
Answer:
If 50%= 26 25%=13 (half)
50%+25%=75%
so 26+13= 39.
75%=39
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.
What is the equation of the following line written in general form? (The y-intercept is -1.)
-2x-y-1=0
2x+y - 1 = 0
2x-y-1 = 0
What are the potential solutions to the equation below? 2In(x+3)=0 x=-3 and x=-4 x=-2 and x=-4 a=2and x=-3 a=2 and x=4
Answer:
x = -2 and x = -4
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]
So, the solution to [tex]2ln(x+3)=0[/tex] is [tex]x=-2[/tex] , using properties of logarithms.
Hence, we can say that the solution to the given equation is [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.

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.

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.

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)

Alternate exterior angles are formed by a transversal intersecting two parallel lines, therefore, your alternate exterior angles are <1 and <5.
Your alternate interior angles are <2 and <6/ <3 and <7.
Corresponding angles are formed when two parallel lines are intersected by a transversal. (<1 and <3)
Vertical angles are formed when two lines intersect each other. Therefore, <1 and <7 fall into this category.
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.

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
