hello
the angles make up co-interior so the two would add up to 180º.
so we can set up a basic equation:
3x-10+5x-30=180
add like terms:
8x-40=180
add 40 to both sides:
8x=220
divide by 8
x=27.5º
hope this helps and have a good day :)

7. The rent for an apartment was $5,600 per year in 2018. If the
rent increased at a rate of 4% each year thereafter, use an
exponential equation to find the rent of the apartment in 2025.
Answers

Answer:
$7369
Step-by-step explanation:
An exponential function is of the form ...
f(x) = a·b^x
where 'a' is the initial value, and 'b' is the growth factor. When the growth is given as a growth rate (4% per year), the growth factor is that value plus 1.
Here, the initial value, for x=0 in 2018, is 5600. So, the exponential model of the rent is ...
r(x) = 5600·(1 +.04)^x
r(x) = 5600·1.04^x . . . . . . . for x years after 2018
__
In 2025, we have x=2025 -2018 = 7. Then the rent is ...
r(7) = 5600·1.04^7 ≈ 7369
The rent of the apartment in 2025 is $7369 per year.

For the first one it is 5x+2
Step-by-step explanation:
(9x+5) - (4x+3) = ?
First you minus the x's together so,
9x-4x which would equal 5x
then you minus the 5 and 3 together so,
5-3 which would equal 2
then you put the 5x and the 2 together and you get
5x+2 :-)

Answers
Answer:
(x + 1)(x + 3)eˣ
Step-by-step explanation:
Since f(x) = (x + 1)²eˣ
df(x)/dx = d[(x + 1)²eˣ]/dx
By the product rule, duv/dx = udv/dx + vdu/dx
where u = (x + 1)² and v = eˣ
So, df(x)/dx = d[(x + 1)²eˣ]/dx
= (x + 1)²deˣ/dx + eˣd(x + 1)²/dx
= (x + 1)²eˣ + eˣd(x + 1)²/d(x + 1) × d(x + 1)/dx (by the chain-rule dy/dx = dy/du × du/dx)
= (x + 1)²eˣ + eˣ[2(x + 1) × 1]
= (x + 1)²eˣ + 2eˣ(x + 1)
= (x + 1)eˣ(x + 1 + 2)
= (x + 1)eˣ(x + 3)
= (x + 1)(x + 3)eˣ
34 petri dishes are prepared with a growth medium. 16 are randomly selected and treated with antibiotic A. The other 18 are treated with antibiotic B. Each dish is inoculated with a bacteria. Several hours later, the diameter of the bacteria colony in each dish is measured in mm, with these results:
A: 8.59, 7.80, 4.11, 8.68, 8.08, 7.86, 6.97, 8.21, 1.72, 8.13, 7.48, 6.33, 8.32, 8.65, 3.06, 8.90

Let µA and µB be the respective population mean diameters across many similar hypothetical experiments. Consider a test at level α = 0.10 of H0 : µA − µB = 0 vs. HA : µA − µB 6= 0.(a) Do you think it is plausible that the samples came from approximately normal distributions? Why or why not?
Answers
Answer:
(a) According to the central limit theorem, the distributions of the sample means of sufficiently large samples randomly selected from a population with mean, μ and standard deviation, σ with replacement will be normally distributed
Therefore, given that the size of the population from which the samples were selected (34 petri dishes) is comparable the sizes of the samples, (16 and 18), therefore, the samples are approximately normal
Also given that the petri dishes were prepared with growth medium designed to increase the growth of microorganisms, with an expected amount of growth, the samples therefore came from approximately normal distributions

Okay, we've kinda been through the steps, so imma give the abridged version:
Volume:
5 x 13 = 33
30 x 19 = 630
LA:
19 x 13 = 247
19 x 12 = 228
5 x 19 = 95
247 + 228 + 95 = 570
SA:
12 x 5 = 60

Area is l*w and since the length is known, solve for width
182/13=13w/13
w=14
Answer:
14 units
Step-by-step explanation:
Given, the area of rectangle = 182 square units
length = 13 units
width = ?
By using the formula to find the area of a rectangle, we have
area of rectangle = length * width
182 = 13 * width
182/13 = width
14 units = width
