1/169=1/3 what's the exponent? how do i figure it out?
Answer:
Step-by-step explanation:
We have been given an equation . We are asked to write the missing exponent for our given equation.
We can see that 169 is square of 13, so we can write left side of our equation as:
We can raise 1 to any power and answer will be same.
Raising 1 to 2nd power, we will get:
Since both numerator and denominator is raised to 2nd power, so we can raise to 2nd power as:
Therefore, our missing exponent is 2.

Given:
A right angle triangle ABC, right angled at C.
To find:
The measure of θ.
Solution:
In a right angle triangle,
[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]
In triangle ABC,
[tex]\tan \theta=\dfrac{AC}{BC}[/tex]
[tex]\tan \theta=\dfrac{2.7}{5}[/tex]
[tex]\tan \theta=0.54[/tex]
It can be written as
[tex]\theta=\tan^{-1}0.54[/tex]
[tex]\theta\approx 28.369[/tex]
Therefore, the measure of θ is 28.369.
Pedro made a pot of coffee for some friends. he served 34 ounces to his friends and then measured that there were 20 ounces leftover. How much coffee did Pedro make?
Answer:
Pedro made 54 ounces of coffee in total.
Step-by-step explanation:
Identify what you know:
1) Pedro gave his friend 34 ounces of coffee.
2) There was 20 ounces of coffee left over after!
So, we need to add the amount of coffee that his friend had, to the amount that's left, to get the total amount that he made.
Let's make an equation, where x equals the total amount!
34 + 20 = x
OR
x - 34 - 20 = 0
Hope this helps!
Answer:
54
Step-by-step explanation:
34+20= 54 ounces of coffee
eva is working two summer jobs, making $16 per hour tutoring and $8 per hour clearing tables. Last week eva worked 3 times as many hours clearing tables as she worked hours tutoring hours and earned a total of $80. Graphically solve a system of equations in order to determine
Answer
y = 3(2) = 6
Thus, she tutored for 2 hours and cleaned tables for 6 hours.
Explanation
These questions are all about writing down mathematically what they are saying in words. Use variables whenever there is an unknown, and try to write equalities based on what is said.
So, taking it one step at a time:
Eva is working two summer jobs,
Cool.
making $16 per hour and $8 per hour clearing tables.
I'm guessing this is $16/hr for tutoring, and $8/hr for clearing tables?
Last week Eva worked 3 times as many hours clearing tables as she worked tutoring hours
Let C = the number of hours Eva worked at clearing tables
Let T = the number of hours Eva worked at tutoring
Last week Eva worked C = 3 * T
and earned a total of $80.
The amount she earned at each place is:
8*C = money from clearing tables
16*T = money from tutoring
8*C + 16*T = 80
Solve a system of equations in order to determine the number of hours Eva worked tutoring last week, X, and the number of hours Eva worked clearing tables last week, Y,
Welp, I guess they wanted X and Y but it doesn't matter. From the equations above we can say:
8*C + 16*T = 80
C = 3*T
That should be enough to solve for:
C = ?
T = ?
Let x = # of hrs spent tutoring, y = # of hrs spent cleaning tables
We know she worked 3 times as many hours cleaning tables as she did tutoring, which implies:
3x = y
Also, her total earnings add up to $80, which implies:
16x + 8y = 80
This gives us the following system of equations:
3x = y
16x + 8y = 80
Let's make the substitution y = 3x into the 2nd equation:
16x + 8(3x) = 80
16x + 24x = 80
40x = 80
x = 2.
Next, plug in x = 2 into the first equation:
y = 3(2) = 6
Thus, she tutored for 2 hours and cleaned tables for 6 hours.
The coordinates of the vertices are (0,0) (5,4) and (7,0). The trapezoid is dilated with scale factor 2 and center (0,0). What are the coordinates of the vertices of the image of the trapezoid?

b. (0,0) (6,12) )(15,12) (21,0)

Answer:
i think its c
sorry if im wrong!
Step-by-step explanation:
Solve for c.
–8 − 6c = –5c
Answer:
c = -8
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
c = -8
Step-by-step explanation:
A dilation has center (0,0). Find the image of the point B ( 5/3, -7/2) for the scale factor 1/3
=======================================================
Explanation:
Since the center of dilation is (0,0), we multiply each coordinate of point B by the scale factor 1/3.
The coordinates of point B are x = 5/3 and y = -7/2
So we have
(1/3)*x = (1/3)*(5/3) = (1*5)/(3*3) = 5/9 as the new x coordinate
and
(1/3)*y = (1/3)*(-7/2) = (1*(-7))/(3*2) = -7/6 as the new y coordinate
The point (5/3, -7/2) moves to (5/9, -7/6)

Trust me bro
The degrees of rotation that will carry the regular pentagon onto itself is 72,144,216,288
What is a pentagon in geometry?In geometry, a pentagon is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°.
Given here: A regular pentagon is rotated clockwise about center P.
Now Since you have 5 vertices, your starting vertex can land in 5 different starting places and still come up with the same figure. So if you take 360/5 you get 72 degree rotations to each consecutive vertex.
or more specifically 360/5=72
Again therefore the pentagon will coincide itself after every integral multiple of 72
Thus 72, 144,216,288 are the required angles of rotation.

Sally bought a sweater for $24.99 with a 25% discount. What is the price of the
sweater after the discount?
There are two ways to do this, the one that makes more logical sense and the faster one
You can first calculate how much is 25%. You do this by $24.99 × 25 ÷ 100
Since you know how much is "discounted", just minus the answer you get above with the original price ($24.99 - $6.2475)
The quicker way is to recognise that "original price" is always 100%. In other words, you can just do 100% - 25% and get 75%. Then, $24.99×75÷100 is your answer.

Which expression is equilvalent to (5g-2h)-(3h+8-4g).
Answer:
9g -5h - 8
Step-by-step explanation:
We first have to get everything out of the parentheses, so we take the negative that is surrounding the parentheses and apply it to the equation inside of it, giving us this: 5g - 2h - 3h - 8 + 4g
Then, all we need to do is simplify it into this expression: 9g -5h - 8

Answer/Step-by-step explanation:
Decompose each shape, find the volume of each cuboid, and add both volumes you get together.
Recall: volume of cuboid = L*W*H
4. Volume of cuboid 1: L*W*H = 12*10*4 = 480 ft³
Volume of cuboid 2: L*W*H = 12*3*5 = 180 ft³
Volume of the shape = 480 + 180 = 660 in.³
5. Volume of cuboid 1: L*W*H = 11*2*5 = 110 yd³
Volume of cuboid 2: L*W*H = 10*4*2 = 80 yd³
Volume of the shape = 110 + 80 = 190 yd³
6. Volume of cuboid 1: L*W*H = 8*3*2 = 48 in.³
Volume of cuboid 2: L*W*H = 14*2*3 = 84 in.³
Volume of the shape = 48 + 84 = 132 in.³
7. Volume of cuboid 1: L*W*H = 5*3*2 = 30 yd³
Volume of cuboid 2: L*W*H = 6*2*5 = 60 yd³
Volume of the shape = 30 + 60 = 90 yd³
8. Volume of cuboid 1: L*W*H = 12*2*18 = 432 in.³
Volume of cuboid 2: L*W*H = 18*5*6 = 540 in.³
Volume of the shape = 432 + 540 = 972 in.³
9. Volume of cuboid 1: L*W*H = 13*11*4 = 572 ft³
Volume of cuboid 2: L*W*H = 13*6*7 = 546 ft³
Volume of the shape = 572 + 546 = 1,118 ft³
