Answer:
x = 1 over 4 ( which is also 0.25 and x=2^-2)
Step-by-step explanation:
4^-3x = 4^x-1
-3x = x - 1
-3x - x = -1
-4x = -1
divide both sides
x = 1 over 4

Answer:
B) 1 8/27
Step-by-step explanation:
First, change all mixed fractions into improper fractions:
2 1/3 = 7/3
1 4/5 = 9/5
7/3 ÷ 9/5
Next, flip the second fraction, and change the division sign into multiplication:
7/3 x 5/9
Multiply across:
7/3 x 5/9 = 35/27
Change into a mixed fraction:
35/27 = 27/27 + 8/27
1 8/27 is your answer.

i got it wrong, thank me latter
The projected sales after 2 years will be $389,350 which is the correct answer would be option (D).
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
Last year's store had total sales of $367,000.
The sales are to increase by 3% per year for the next 2 years.
To determine the projected sales in 2 years
The projected sales in next year = 3% of $367,000 + $367,000
The projected sales in next year = (3/100) × 367,000 + 367,000
The projected sales in next year = 11,010 + 367,000
The projected sales in next year = $378,010
The projected sales after 2 year = 3% of $378,010 + $378,010
The projected sales after 2 year = (3/100) × 378,010 + 378,010
The projected sales after 2 years = 11,340 + 378,010
The projected sales after 2 years = $389,350
Thus, the projected sales after 2 years will be $389,350.

Answer:
A. 2/(1 -x)²
Step-by-step explanation:
The derivative of a ratio is given by the formula ...
d(u/v) = (v·du =u·dv)/v²
Here, we have ...
u = 1+x; du = 1·dx
v = 1 -x; dv = -1·dx
Then ...

Answer:
(2x-10) +x +(x+10) = 180x = 45(2x-10)° = 80°(x+10)° = 55°x° = 45°Step-by-step explanation:
The equation is an expression of the fact that the sum of the angles in a triangle is 180°.
(2x -10)° +x° +(x +10)° = 180°
For the purposes of the answer box, I'd leave off the degree symbol:
(2x -10) +x +(x +10) = 180
__
This simplifies to ...
4x = 180
x = 45
Then the angles (CW from top) are ...
(2·45 -10) = 80°
(45 +10)° = 55°
(45)° = 45°

What is the inverse of the following statement?
If two triangles are congruent, then their corresponding angles are congruent.
A. If the corresponding angles of two triangles are congruent, then the triangles are congruent.
B. If two triangles are not congruent, then their corresponding angles are not congruent.
C. If two triangles are congruent, then their corresponding angles are congruent.
D. If the corresponding angles of two triangles are not congruent, then the triangles are not congruent.
Answer:
A
Step-by-step explanation:
A, because you just have to flip the cause and effect.
If two triangles are congruent, then their corresponding angles are congruent.
So, if the corresponding angles are congruent, then the triangles are congruent
You can use this property for problems similar to this one, that have cause and effect relationships.
Use the information below to determine if AB and CD are parallel, perpendicular or neither.
(0, – 4), (-1, — 7), (3, 0), (-3, 2)
Answer:
perpendicularStep-by-step explanation:
Calculate the slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Let m₁ and m₂ are the slopes of AB and CD.
Then
if m₁ = m₂ → lines are parallel
if m₁ · m₂ = -1 → lines are perpendicular
[tex]A(0;\ -4);\ B(-1;\ -7)\\\\m_{AB}=\dfrac{-7-(-4)}{-1-0}=\dfrac{-7+4}{-1}=\dfrac{-3}{-1}=3\\\\C(3;\ 0);\ D(-3;\ 2)\\\\m_{CD}=\dfrac{2-0}{-3-3}=\dfrac{2}{-6}=-\dfrac{2:2}{6:2}=-\dfrac{1}{3}[/tex]
[tex]m_{AB}\neq m_{CD}[/tex] - no parallel
[tex]m_{AB}\cdot m_{CD}=3\cdot\left(-\dfrac{1}{3}\right)=-\dfrac{3}{3}=-1[/tex] - perpendicular
Sam is developing a metric to try to measure how generous an individual is. In order to evaluate whether it is actually measuring generosity, Sam is checking to see if there is any correlation between a person's score on the metric and the amount of money they donate to charities or give to others in need. In other words, Sam is evaluating the _____ of the metric.
By checking to see if there is correlation, Sam is evaluating the criterion validity of the metric.
How to determine the measured parameter of the metricFrom the question, we understand that Sam tests the metric to check for the presence or absence of correlation in the metric.
This, in other words means that Sam is checking the criterion validity of the metric.
Hence, the true statement is that Sam is evaluating the criterion validity of the metric.

There are 150 males and 50 females participating in a marathon. What percent of the participants are female?
Hey there!
Answer: 25% of participants are females

50+150=200
female=50
50÷200×100=25%
