===========================================
Work Shown:
40 coins total
16 are dimes
40-16 = 24 coins are not dimes
Half of this is 24*(1/2) = 12 which are quarters. The other half (12) are pennies and nickels
n = number of nickels
p = number of pennies
This means n+p = 12 so that we have 12 pennies and nickels combined.
"There are 2 nickels for every penny", so we can write n = 2p. If p = 1, then n = 2. If p = 2, then n = 4, etc. Whatever p is, we double it to get n.
So,
n+p = 12
2p+p = 12
3p = 12
p = 12/3
p = 4, we have 4 pennies
n = 2p
n = 2*4
n = 8 and 8 nickels

Answer:
Option (B) is correct, 4 pennies.
HELP PLEASE I REALLY NEED THE HELP ON THIS.
for questions 8 and 9, you just need to use a ruler to fine how many inches, centimeters, or millimeters each line segment is. (make sure to properly read the question to see if they’re asking for the measurement in in, cm, or mm.) i won’t be able to give you these measurements because the picture became smaller when you uploaded it, but it shouldn’t be that hard for you!
for question 10, use a ruler to draw and label your own line segment.
on 10a, draw a line segment that is 3 1/4 inches long, then label one end of the segment ‘H’ and one end ‘J’
for 10b, draw a line segment that is 5 7/16 inches long, then label one end of the segment ‘M’ and the other ‘N’.

Suppose you have a triangle, and you want to construct a similar triangle. Which two
transformations will result in a triangle that is similar, but is not congruent?
Rotation and Reflection
Reflection and Translation
Reflection and Dilation
Translation and Rotation
Explanation:
The transformations of translation, reflection and rotation are considered rigid motions. They keep the figure the same size just it has been shifted around in some way. In contrast, a dilation will alter the size to make it larger or smaller depending on what the scale factor is.
Only choice C has "dilation" as part of the answer, so it must be the answer. The other choices are purely rigid motions that will keep the triangle the same size and shape. In other words, the preimage and image are congruent for choices A,B, and D.
i don’t know how to show that the probability is 3/4 or how to work it out helppp
Step-by-step explanation:
There are 12 beads. 2 are blue, 1 is green, 3 are purple, and the rest (6) are red.
So there are 9 beads that are purple or red.
The probability is therefore 9/12, which reduces to 3/4.
Answer:
Show all colored beads on the bottom draw a line in the middle and in the top show all red and purple colored beads.
Step-by-step explanation:
Well first we need to work out the number of beads total.
2 blue + 1 green + 3 purple + 6 red = 12
9 purple or red,
9/12
Simplified,
3/4
Show all colored beads on the bottom draw a line in the middle and in the top show all red and purple colored beads.

Answer:
SU = 2PX = 6 2/3Step-by-step explanation:
The product of distances to the circle along a secant is the same for all secants intersecting a given point.
a. Secants SW and QT intersect at U. Thus ...
(UT)(UQ) = (US)(UW)
(1.5)(4) = (SU)(3)
SU = (4)(1.5)/3
SU = 2
__
b. Secants PT and PX intersect at P. Thus ...
(PQ)(PT) = (PR)(PX)
PX = (PQ)(PT)/PR) = (2.5)(2.5 +4 +1.5)/3 = 20/3
PX = 6 2/3

Given the lengths of two sides of a triangle, find the range for the length of the third side. (Range means find between which two numbers the length of the third side must fall.) Write an inequality. 34 and 12
Answer:
[tex]22 < X < 46[/tex]
Step-by-step explanation:
Given
Two sides of a triangle; 34 and 12
Required
Determine the range of the third side
Represent the third side with X
To determine the range of the third side; two of the following conditions must be satisfied'
[tex]34 + X > 12[/tex]
[tex]34 + 12 > X[/tex]
[tex]12 + X > 34[/tex]
Solving 34 + X > 12
Subtract 34 from both sides
[tex]34 - 34 + X> 12 - 34[/tex]
[tex]X > -22[/tex]
Solving 34 + 12 > X
[tex]34 + 12 > X[/tex]
[tex]46 > X[/tex]
Solving 12+ X > 34
Subtract 12 from both sides
[tex]12 - 12 + X > 34 -12[/tex]
[tex]X > 22[/tex]
Write out the results
[tex]X > -22[/tex]
[tex]46 > X[/tex]
[tex]X > 22[/tex]
The first inequality will be discarded because it accommodates negative digits;
So, we're left with
[tex]46 > X[/tex] and [tex]X > 22[/tex]
This can be rewritten as
[tex]X < 46[/tex] and [tex]22 < X[/tex]
Combine both inequalities;
[tex]22 < X < 46[/tex]
Hence, the range of the third length is [tex]22 < X < 46[/tex]

Given: f(x) = x2, g(x) = x + 6, h(x) = 7
Find f(g[h(x)]).
55
169
26
Answer:
169
Step-by-step explanation:
f(x) = x^2, g(x) = x + 6, h(x) = 7
f(g[h(x)])
Replace h(x) with 7
f(g(7))
g(7) = 7+6 = 13
Replace g(7) with 13
f(13) = 13^2 = 169
Answer:
169
Step-by-step explanation:
We are asked to find:
f(g[h(x)])
We know that f(x) = x^2, g(x) = x + 6, and h(x) = 7
Therefore, we can begin by substituting 7 for h(x)
f(g[h(x)]), h(x)=7
f(g[7])
Now, we must find g(7). We know that g(x) is x+6
g(x)=x+6
We want to find g(7). Plug 7 in for each x.
g(7)=7+6
Add 7 and 6
g(7)=13
Substitute 13 in for g(7)
f(g[7])
f(13)
Finally, find f(13). We know that f(x)=x^2
f(x)=x^2
We want to find f(13). Plug 13 in for each x.
f(13)=13^2
13^2= 13*13= 169
f(13)=169
169
Therefore, f(g[h(x)]) is 169
A lot consisting of 50 bulbs is inspected by taking at random 10 bulbs and testing them. If the number of defective bulbs is at most 1, the lot is accepted; otherwise it is rejected. If there are 10 defective bulbs in the lot, what is the probability of accepting the lot?
Answer:
0.3487
Step-by-step explanation:
The probability of accepting the lot If there are 10 defective bulbs in the lot is; 0.3487
This involves binomial probability distribution which is given by the formula;P(X = r) = ⁿ[tex]C_{r}[/tex] × [tex]p^{r}[/tex] × [tex]q^{1 - r}[/tex]
We are given;Number of bulbs taken at random = 10
We are told that if the number of defective bulbs is at most 1, then the lot is accepted.
This means that probability of success is; p = 1/10 = 0.1
q = 1 - p
q = 1 - 0.1
q = 0.9
If there are 10 defective bulbs, then the probability of accepting the lot is;P(X = 0) = ¹⁰[tex]C_{0}[/tex] × [tex]0.1^{0}[/tex] × [tex]0.9^{10 - 0}[/tex]
P(X = 0) = 0.3487

The position of an object at time t is given by s(t) = -9 - 3t. Find the instantaneous velocity at t = 8 by finding the derivative. 20 POINTS
Work Shown:
s(t) = -9 - 3t
s ' (t) = -3 ... apply the derivative
The position function is linear, so the derivative is constant. The slope of any straight line is the same regardless of where you are on it, so that's why the velocity is a single fixed number. Put another way, the slope of the line is exactly the velocity (since slope = rise/run = change in distance over change in time). It doesn't matter what the value of t is, the velocity will be -3
