Answer:
No
Step-by-step explanation:
If all 30 coins were nickels and dimes, there would be 10 dimes and 20 nickels, for a total value of $2.00. Trading a dime and 2 nickels for an equal number of quarters raises the value to $2.00 -0.10 -2(0.05) +3(0.25) = $2.55.
That is, each such trade adds $0.55 in value to the total amount. Since the original difference of $3.00 -$2.00 = $1.00 is not evenly divisible by $0.55, there cannot be twice as many nickels as dimes.
__
For 30 coins, possible numbers of {nickels, dimes, quarters} are ...
{21,2,7}, {18,6,6}, {15,10,5}, {12,14,4}, {9,18,3}, {6,22,2}, {3,26,1}, {30 dimes}
Note that we can have 1.5, 3, or 10.5 times as many nickels as dimes, but not 2 times as many.
y varies directly as X. If X=2 and y=10. Find Y when X=7
Answer:
y= 35
Step-by-step explanation:
y directly proportional to x
where x= 2, y= 10
y=kx
10= k× 2
k= 10/2
k= 5
to find y when x is 7
y = kx
y = 5× 7
y= 35

Angle Bisector.
Step-by-step explanation:
Okay.
SU is the line across the triangle.
It isn't perpendicular because it will meet the lines eventually.
Median is a number.
I believe It's the Angle Bisector, but i'm going off of a gut feeling.
Which triangle cannot be used to find the slope of the line?

During its first year, there were 138 volunteers at a community outreach program. Over the next 2 years, there were 156 volunteers and 175 volunteers, respectively. What is the percent of increase in volunteers from Year 1 to Year 2 and from Year 1 to Year 3? Round to the nearest tenth percent if necessary.
Answer:
0.1%
Step-by-step explanation:
138 into a percent=1.38%
156 into a percent=1.56%
175 into a percent=1.75%
1.38-1.56=0.18
1.56-1.75=0.19
0.19-0.18= 0.1%
The increase in volunteers from year 1 to year 2 is 13.04 % and the increase from year 1 to year 3 is 26.81 %.
PercentageThe percentage can be defined as a relative value that represents the hundredth part of any quantity.
Given that the number of volunteers in a program during year 1, year 2 and year 3 are 138, 156 and 175 respectively.
The percentage of increase in volunteers from year 1 to year 2 is given below.
Volunteers (%) = [tex]\dfrac {156-138}{138} \times 100[/tex]
Volunteers (%) = 13.04%
The percentage of increase in volunteers from year 1 to year 3 is given below.
Volunteers (%) = [tex]\dfrac {175-138}{138} \times 100[/tex]
Volunteers (%) = 26.81 %
Hence we can conclude the increase in volunteers from year 1 to year 2 is 13.04 % and the increase from year 1 to year 3 is 26.81 %.

The grizzly bear population in Yellowstone National Park in 1970 was about 270. Over the next 35 years, it increased by about 115%. What was the population in 2005?
Answer: 311 bears
Step-by-step explanation:
Population increased by 115% in the 35 years from 1970 to 2005.
Population in 2005 is:
= 270 * 115/100
= 310.5
= 311 bears
Answer:
581
Step-by-step explanation:
270x%115=310.5
We have to round 310.5 to the nearest So 310.5 will be 311
So if it increased by 115% we have to add the 115% to 270
270+311= 581
By the 2005 the population will be 581

A. 3566 sq. units
B. 1528 sq. units
C. 1783 sq. units
D. 3057 sq. units
y’all help please
Answer:
C
Step-by-step explanation:
A heptagon is a polygon with 7 triangles. (a)
Thus, The area (A) will be = 7a
[tex]The \ area \ of \ \ triangle \ = (1/2) \times b \times h[/tex]
where;
b = base
h = height
So;
[tex]7a = \dfrac{1}{2}(bh)[/tex]
where;
b = 22.15 unit and h = 23 unit
∴
[tex]A = \dfrac{7 \times b \times h}{2} \\ \\ A = \dfrac{7 \times 22.15 \times 23}{2} \\ \\ A = 1783.07 \ sq. units \\ \\ A \simeq 1783 \ sq. units \\ \\[/tex]

13, 14, 19. AAS — 13: WYX≅AYZ; 14: CFD≅CEB; 19: DEH≅GEF
15, 16. not possible
Step-by-step explanation:
9. You're looking for three sides, or two sides flanking a congruent angle. Here, the angle is not between the two sides, so the SAS theorem does not apply. Proving congruence is not possible.
__
13, 14, 19. You have two adjacent angles, followed by a side, so the AAS theorem will prove congruence.
When you write the congruence statement, you need to make sure the nodes are named in corresponding order. It can be useful to name the nodes in the same order as the elements you claim for congruence. For these, we name the two angle nodes first, then the other end of the side.
13: WYX≅AYZ; 14: CFD≅CEB; 19: DEH≅GEF
__
15, 16. With only one angle and one side, it is not possible to prove congruence.
_____
Additional comment
With these theorems, you are looking for angles or sides that are adjacent (next to each other). In figure 9, there are two sides and an angle, so you might be tempted to claim SAS congruence. The name SAS means the angle must be between the two sides. In that figure, the two sides are adjacent, and the angle is adjacent to only one of the sides (not between them). Hence SAS does not apply.
(You will find later that two sides and a non-adjacent angle will define a unique triangle if, and only if, the angle is opposite the longest of the two given sides. In figures like these, no side lengths are given, and you are not allowed to rely on appearances.)

Ulani is constructing a triangle that has sides measuring 12 cm and 28 cm. Which measurements could be the length of the third side? Select two options.
Answer:
16 < n < 40
Step-by-step explanation:
use triangle inequality theorem:
n = length of third side
12 + 28 > n; n > 40
12 + n > 28; n > 16
n + 28 > 12 (this inequality can be discounted because it results in a negative)
