Answer:
Copper = x= 36.19
Step-by-step explanation:
The number of copper is unknown
Gold = 1/3
Silver = 1/5
Bronze =2/7
Copper = x
Total coins = 200
Gold = 1/3 of 200
= 1/3 × 200
= 200/3
= 66.67
Silver = 1/5 × 200
= 200/5
= 40
Bronze = 2/7 × 200
= 400/7
= 57.14
Total = gold + silver + bronze + copper
200 = 66.67 + 40 + 57.14 + x
200 = 163.81 + x
200 - 163.81 = x
x = 36.19
Copper = x= 36.19
. has endpoints B(5, 9) and C(–4, –3). Find the coordinates of the midpoint of . (0.5, 1.5) (1, 3) (0.5, 3) (1, 6)
Answer:
(0.5,3)
Step-by-step explanation:
Hi there!
We are given a line that has the endpoints of (5,9) and (-4,-3); we need to find the midpoint of the line.
The midpoint formula is given as ([tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2}}{2}[/tex]), where [tex]x_{1}[/tex], [tex]x_{2}[/tex], [tex]y_{1}[/tex], and [tex]y_{2}[/tex] are values of coordinate points
to avoid any confusion, we can label the values of the coordinates and then substitute them into the formula to find the midpoint
[tex]x_{1}[/tex]=5
[tex]y_{1}[/tex]=9
[tex]x_{2}[/tex]=-4
[tex]y_{2}[/tex]=-3
now substitute into the formula
so to find the value x in the midpoint, we'll use this part of the formula: [tex]\frac{x_{1}+x_{2} }{2}[/tex]
substitute 5 and -4 into the formula
[tex]\frac{5+-4}{2}[/tex]
do the addition on the numerator
[tex]\frac{1}{2}[/tex] or 0.5
now let's find the value of y in the midpoint. we'll use this part of the formula: [tex]\frac{y_{1}+y_{2}}{2}[/tex]
substitute 9 and -3 into the formula
[tex]\frac{9+-3}{2}[/tex]
do the addition on the numerator
[tex]\frac{6}{2}[/tex] or 3
Therefore the midpoint is (0.5,3)
Hope this helps! :)
which phase best describes the translation from tge graph y=2(x-15)^2 to the graph of y=2(x-11)^2+3?
Answer:
Graph translates 4 units to the left then 3 units up.
Step-by-step explanation:
The constant in the bracket changes for - 15 to -11 . A change of + 4.
This shifts the whole graph horizontally 4 units to the left.
The + 3 moves the whole graph 3 units upwards.

Step-by-step explanation:
Object distance (u) = -100cm Focal length (f) = 50cm Image distance = v By lens formula; 1v−1u=1f1v−1u=1f ⇒ 1v−1−100=1501v−1−100=150 ⇒1v=150−11001v=150−1100 ⇒1v=2−1100−11001v=2−1100−1100 v =100cm Hence the image is formed at 100 cm behind the lens.

PLEASE HELP !! two angles in a triangle have measurements of 20 degrees and 50 degrees. what is the measure of the third angle? the options are 70 degrees, 30 degrees, 110 degrees, and 120 degrees
9514 1404 393
Answer:
110°
Step-by-step explanation:
The sum of angles in a triangle is 180°. The measure of the third angle is ...
180° -20° -50° = 110° . . . third angle
Answer:
The measurement of third angles of triangle is 110°.
Step-by-step explanation:
Given :-
Two angles in a triangle have measurements of 20° and 50 °.
To Find :-
Measurement of third angles of triangle
Solution :-
We know that the sum of all angles of triangle is 180°.
Measurement of third angles = x20° + 50° + x = 180°
combine like terms
70° + x = 180°
subtract both side from 70°.
70° - 70° + x = 180° - 70°
x = 110 °
Hence, measurement of third angie of triangle is 110°.
1. A merchant sets the selling price of an article 40% above what it cost him. Then, seeing it did not sell, he decided to reduce the figure by 15%. The final selling price was $8.65. What did the article originally cost?
==========================================
Work Shown:
x = original cost (in dollars)
1.40x = increasing the cost by 40%
0.85*1.40x = decreasing the previous cost (1.40x) by 15%
Notice how a decrease of 15% means you pay the remaining 85% of the price, which is where the 0.85 comes from.
The expression 0.85*1.40x simplifies to 1.19x after multiplying the 0.85 and 1.40
-------------------------
The expression 1.19x is the final cost after the increase of 40% and the decrease of 15%
Set this equal to 8.65 and solve for x
1.19x = 8.65
x = 8.65/1.19
x = 7.2689075630252 which is approximate
x = 7.27 dollars
-------------------------
Let's check the answer
x = 7.27
1.40x = 1.40*7.27 = 10.178 = 10.18
After an increase of 40%, the cost is now $10.18
Now decrease it by 15%
discount = 15% of 10.18 = 0.15*10.18 = 1.527 = 1.53
The customer saves $1.53 and the final price is 10.18-1.53 = 8.65
So everything works out as we expect. The answer is confirmed.
Jeremiah buys 3 lbs of cheese at $3.50
a pound. He also buys 5 lbs of sliced
turkey. If he spends $46.75 in total for
the cheese and turkey, what is the
price per pound of sliced turkey?
Answer: $7.25 per pound
Step-by-step explanation:
3x3.5 + 5x = 46.75
5x+10.5 = 46.75
5x = 36.25
x = 7.25
Answer:
the price per pound for the turkey would be 7.25
Step-by-step explanation:
first you would do 3x3.50 to find the total cost for the cheese
now you subtract that from 46.75
once you have that answer you divide by 5 :)

Total health care costs in the United States in 2016 was $1.7 trillion. he US population was 290.9 million. What was the average amount spent per person on health care?
Answer:
$5,843.9
Step-by-step explanation:
2016
Total health care cost in US = $1.7 trillion
= $1,700,000,000,000
Population in US = 290.9 million.
= 290,900,000
Average amount spent per person on health care = Total health care cost in US / Population in US
= 1,700,000,000,000 / 290,900,000
= $5843.9326228944
Approximately,
$5,843.9

In which triangle is the value of x to tan^-1(3.1/5.2)??
(Images may not be drawned on the scale)
The angle of x in the right angle triangle is 30.80 degrees
Right angle triangle:
Right angle triangle have one of it angles as 90 degrees. The angles can be found using trigonometric ratios.
Let's find the angle x using trigonometric ratios;
tan x = opposite / adjacent
Therefore,
tan x = 3.1 / 5.2
x = tan⁻¹0.59615384615
x = 30.7991697243
x ≈ 30.80°
Therefore, the angle of x is 30.80 degrees

Find the area of the given quadrilateral.
Pls :)
I think your teacher may have made a typo. Refer to the diagram below. If we ignore segment ZA for now, we can see a rectangle forms with angle W = angle Y = 90. Also, we can see that WX = 6 is the horizontal base and WZ = 8 is the vertical height.
However, the side opposite WZ (which is XY) should also be 8 cm tall, and not 6 cm. If XY was 6 cm, then point Y would move to where point A is located (and the quadrilateral would be WXAZ instead of WXYZ). This new quadrilateral would not have a 90 degree angle at point Y's new location.
In other words, if we want angle Y to be 90 degrees, then side XY must be 8 units long. I have a feeling this is where the typo is, but your teacher might have been intending to say something else.
how much should your mom set aside and invest in a fund earning 3% compounded quarterly is she needs 85,000.00 in 20 months
Answer:
PV= $73,201.14
Step-by-step explanation:
Giving the following information:
Future value (FV)= $85,000
Number of periods (n)= 20 months
Interest rate (i)= 0.03/4= 0.0075
To calculate the lump-sum required to reach the objective, we need to use the following formula:
PV= FV / (1 + i)^n
PV= 85,000 / (1.0075^20)
PV= $73,201.14
An empty container has a capacity of 60000 liters to 1 s.f. Tony pours in 5400 liters of water to 2 s.f. He says he filled more than 10 % of container is he correct ? Show working
Answer:
Tony poured is 9% of the total
Step-by-step explanation:
Given data
The capacity of the container= 60000 liters
Amount of water that tony pours= 5400 liters
Let us compute the percentage to know if it is up to 10%
= 5400/60000*100
=0.09*100
=9%
Hence the amount of water Tony poured is 9% of the total

what is the answer to 2x + 9(x – 1) = 8(2x + 2) – 5
Answer:
-4 =x
Step-by-step explanation:
2x + 9(x – 1) = 8(2x + 2) – 5
Distribute
2x +9x -9 = 16x+16 -5
Combine like terms
11x-9 = 16x +11
Subtract 11x from each side
11x-9-11x = 16x-11x+11
-9 = 5x+11
Subtract 11 from each side
-9-11 = 5x+11-11
-20 = 5x
Divide by 5
-20/5 = 5x/5
-4 =x
