answer:
the 4 is in the hundreds place
step-by-step explanation:
this is how i figured this out-
since the 2 is in the one's place and the 3 in the tenths place that makes the 4 in the hundreds place
also if you take 432 as its own number, the 4 is also in the hundreds place

What is the surface area of a square prism with a base side length of 9 cm and a slant height of 7cm.
Answer:
414cm^2
Step-by-step explanation:
Given data
Base a= 9cm
Hence the expression for the surface area is
SA=2a^2+4ah
A=2*9^2+4*9*7
A=162+252
A=414cm^2
Hence the surface area is 414cm^2
If the volume of figure A is 135 and the volume of figure B is 625, find the ratio of their surface areas.

Last year, 50 students attended the winter carnival. This year, 60 students attended the carnival. Which statement below correctly describes the percent change from last year to this year?
Answer: 20% increase
Step-by-step explanation:
change/ original number
(60 - 50 / 50) x 100 = 20
20%
Answer:
An increase of 20%
Step-by-step explanation:
50/100=60/x
Cross Products
50x=6000
Divide 50 by both sides
x = 120
60 is 120% of 50, so there is a 20% increase

Which THREE sets of ordered pairs represent functions? A) {(15, –3), (–6, 9), (–3, 0), (–1, 16), (5, 5)} B) {(6, 0), (–12, –16), (–6, 10), (20, –7), (16, 9)} C) {(12, –18), (15, 1), (12, 5), (0, 9), (–5, –17)} D) {(–13, 4), (7, –15), (–13, 9), (6, –12), (–18, 0)} E) {(10, 9), (–2, –16), (–6, 7), (5, 8), (8, –16), (–11, 9)}
Answer:
A, B, and E
Step-by-step explanation:
A function has only ONE out put for each input. For example in C 12 has two outputs, -18 and 5 so that set is NOT a function.

a side of a cube measures 4 centimeters and a side of a smaller cube measures 2 centimeters. the volume of the larger cube is how many times the volume of the smaller cube
a: 6
b: 2
c: 8
d: 4
Answer:
C
Step-by-step explanation:
Given the sides of cubes in the ratio a : b , then
ratio of volumes = a³ : b³
Here ratio of sides = 2 : 4 = 1 : 2 ( smaller : larger ) , so
ratio of volumes = 1³ : 2³ = 1 : 8
Then the volume of the larger cube is 8 times the volume of the smaller.
What is the surface area of the rectangular prism?
Answer:
348 in.² is the answer.
Step-by-step explanation:
To find our answer we will multiply each number by each other.
6 x 8 = 48
6 x 9 = 54
8 x 9 = 72
Now we have our numbers 48, 54, and 72, we will multiply each one by 2.
48 x 2 = 96
54 x 2 = 108
72 x 2 = 144
For our final step we will add all these together to find our surface area. 96 + 108 + 144 = 348. Therefore, 248 in² is our answer.

Fernando followed two diagonal paths, Paths 1 and 2, to get from his house, F, to a neighborhood corner store, C, as shown below.
Answer:
42 meters
Step-by-step explanation:
Given
See attachment for complete question
Required
Calculate distance FC
FC is calculated as:
[tex]FC = Path\ 1 + Path\ 2[/tex]
Where
[tex]Path\ 1 = FB[/tex]
[tex]Path\ 2 = BC[/tex]
Considering [tex]\triangle FEB[/tex], we have:
[tex]FB^2 = FE^2 + BE^2[/tex] --- Pythagoras theorem
Where
[tex]FE = FD - BA[/tex]
[tex]FE = 22m - 15m[/tex]
[tex]FE = 7m[/tex]
and
[tex]BE = CD - CA[/tex]
[tex]BE = 32m - 8m[/tex]
[tex]BE = 24m[/tex]
So:
[tex]FB^2 = FE^2 + BE^2[/tex]
[tex]FB^2 = 7^2 +24^2[/tex]
[tex]FB^2 = 49 +576[/tex]
[tex]FB^2 = 625[/tex]
Take square roots of both sides
[tex]FB = 25[/tex]
So:
[tex]Path\ 1 = 25[/tex]
Considering [tex]\triangle BAC[/tex], we have:
[tex]BC^2 = BA^2 + AC^2[/tex] --- Pythagoras theorem
Where:
[tex]BA = 15[/tex] and [tex]AC = 8[/tex]
So, we have:
[tex]BC^2 = 15^2 + 8^2[/tex]
[tex]BC^2 = 225 + 64[/tex]
[tex]BC^2 = 289[/tex]
Take square roots of both sides
[tex]BC = 17[/tex]
So;
[tex]Path\ 2= 17[/tex]
Recall that:
[tex]FC = Path\ 1 + Path\ 2[/tex]
[tex]FC = 25 + 17[/tex]
[tex]FC = 42[/tex]
A rental car company charges $44.94 per day to rent a car and $0.07 for every mile driven. Levi wants to rent a car, knowing that: He plans to drive 500 miles. He has at most $460 to spend.

We are finding hypotenuse but first we find the length of all sides of the two squares to find the two sides of the triangle then we find hypotenuse.
Answer:
Step-by-step explanation:
OH you have to find what the lengths of the sides of the squares are, It would have been easier if they made the area 36 because that is a squared number and easy to find but because they didn't you just have to put 32 into a square root and the output would be 5.6.
why are we doing this? because 5.6*5.6=32, the area of the square. that means that 5.6 and 5.6 can be plugged into the A^2+B^2=C^2 equation 5.6^2+5.6^2=c^2 the missing side.
=984 should be the missing side but do the work yourself because that number that I came up with doesn't look right.

Angie has already walked 1 kilometer this week, plus she plans to walk 1 kilometer during
each trip to school. After 23 trips to school, how many kilometers will Angie have walked in
total?
Answer:
24 km
Step-by-step explanation:
Since each trip takes 1 km, we multiply 23 by 1 to get 23 km in total. We then add this onto the 1 km that she has already walked to get 24 km as our answer.

What is the area of the shape? (Number only)
Answer: 282.15cm. ^2(squared)
Step-by-step explanation:
Hey!
So for this problem we first need our formula.
For a right triangle, it would be:
A=1/2bh
B=base (bottom line)
H= height (middle line)
Since that’s is technically two right triangle to make 1, you could just multiple your final result by 2 or just do base times height.
We’re going to do 1/2bh x 2 so I can show you both ways.
Our base is 27, so we are going to split that in half into 13.5.
We already have our height so now all we do is multiply.
13.5 x 20.9=282.15
Now we divide by 2 (if you only wanted one half of the triangle) and we would get 141.07.
Since you need the whole triangle area, your final answer would be 282.15cm. ^2(squared)

The exponential decay function A = A0(1/2)^t/P can be used to determine the amount A, of a radioactive substance present at time t, if A0 represents the initial amount and P represents the half-life of the substance.
If a substance loses 70% of its radioactivity in 500 days, determine the period of the half-life.
Show your work.
Answer:
The half-life of the substance is about 288 days.
Step-by-step explanation:
The exponential decay function:
[tex]\displaystyle A=A_0\left(\frac{1}{2}\right)^{t/P}[/tex]
Can determine the amount A of a radioactive substance present at time t. A₀ represents the initial amount and P is the half-life of the substance.
We are given that a substance loses 70% of its radioactivity in 500 days, and we want to determine the period of the half-life.
In other words, we want to determine P.
Since the substance has lost 70% of its radioactivity, it will have only 30% of its original amount. This occured in 500 days. Therefore, A = 0.3A₀ when t = 500 (days). Substitute:
[tex]\displaystyle 0.3A_0=A_0\left(\frac{1}{2}\right)^{500/P}[/tex]
Divide both sides by A₀:
[tex]\displaystyle 0.3=\left(\frac{1}{2}\right)^{500/P}[/tex]
We can take the natural log of both sides:
[tex]\displaystyle \ln(0.3)=\ln\left(\left(\frac{1}{2}\right)^{500/P}\right)[/tex]
Using logarithmic properties:
[tex]\displaystyle \ln(0.3)=\frac{500}{P}\left(\ln\left(\frac{1}{2}\right)\right)[/tex]
So:
[tex]\displaystyle \frac{500}{P}=\frac{\ln(0.3)}{\ln(0.5)}[/tex]
Take the reciprocal of both sides:
[tex]\displaystyle \frac{P}{500}=\displaystyle \frac{\ln(0.5)}{\ln(0.3)}[/tex]
Use a calculator:
[tex]\displaystyle P=\frac{500\ln(0.5)}{\ln(0.3)}\approx287.86[/tex]
The half-life of the substance is about 288 days.
