Step-by-step explanation:
[tex]\sf \log_4(64)^{n+1}=log_5(625)^{n-1}[/tex]
Change 64 to an exponent with base 4 and 625 to an exponent with base 5:
[tex]\implies \sf \log_4(4^3)^{n+1}=log_5(5^4)^{n-1}[/tex]
Using exponent rule [tex](a^b)^c=a^{bc}[/tex]
[tex]\implies \sf \log_4(4)^{3(n+1)}=log_5(5)^{4(n-1)}[/tex]
Using log rule: [tex]\log_a(b^c)=c \log_a(b)[/tex]
[tex]\implies \sf 3(n+1)\log_4(4)}=4(n-1)log_5(5)[/tex]
Using log rule: [tex]\sf \log_a(a)=1[/tex]
[tex]\implies \sf 3(n+1)=4(n-1)[/tex]
[tex]\implies \sf 3n+3=4n-4[/tex]
[tex]\implies \sf 3+4=4n-3n[/tex]
[tex]\implies \sf n=7[/tex]

3. Jenny puts two wooden blocks together. One block has a length of 5 in., a width of 4 in., and a
height of 5 in. The other block has a height of 4 in., a length of 5 in., and a width of 2 in. What is the
combined volume of the blocks?
Answer:
140 inches cubed
Step-by-step explanation:
Use the formula V = length * width * height to find the volumes of each block, then add them together to get the combined volume. So, (5 * 4 * 5) + (4 * 5 * 2) = 140 inches cubed, which is the combined volume.
Hopefully this helps- let me know if you have any questions!

A store sells a workout outfit that consists of a jacket, a t-shirt, and a pair of shorts. The store purchases the jacket for $34, the t-shirt for $9, and the shorts for $12. The percent of markup is 28%. Find the selling price of the outfit.
PS: include show work please I have to submit this in like 3 hours thankyou
Answer:
The Outfit costs $70.4.
Step-by-step explanation:
Add the selling price together
34 + 9 + 12 = 55
Multiply by the markup (Profit)
100% = 1
28% = 0.28
55 x 1.28 = 70.4
Garrett buys a bag of cookies that contains 8 chocolate chip cookies, 6 peanut butter cookies, 7 sugar cookies and 7 oatmeal cookies. What is the probability that Garrett reaches in the bag and randomly selects a chocolate chip cookie from the bag, eats it, then reaches back in the bag and randomly selects an oatmeal cookie
Answer:
p(chocolate chip) = 2/7
p(oatmeal) = 7/27
Step-by-step explanation:
probability = favorable outcomes/total outcomes
First, add up all the cookies in the bag.
8 + 6 + 7 + 7 = 28
Next find the probability of selecting a chocolate chip cookie. Since there are 8 chocolate chip cookies and 28 cookies in the bag, create a fraction.
p(chocolate chip) = 8/28
reduce by 4
p(chocolate chip) = 2/7
Now that the cookie was eaten that will reduce the number of chocolate chip cookies to 7 and the overall number of cookies to 27.
There are 7 oatmeal cookies and 27 total cookies, so create the fraction.
p(oatmeal) = 7/27
Does x/x+11 simplify to 1/11? Why or why not ?
Answer:
No.
Step-by-step explanation:
Because only x / 11x simplifies to 1 / 11
X and 11 are not the same, therefore you cannot simplify them
The speeds of four racing cars are 146.633 mph, 150 mph, 151.971 mph, and 141.428 mph. Find the average speed of the 4 cars correct to 5 significant digits.

How can I find the value of X?
Answer:
D
Step-by-step explanation:
Remark
The first thing you must do is notice that <D = <BEA. Mark it that way on your diagram.
The Second thing you need to notice is that <BEA and <A are equal because <A and <D are marked as equal.
So both the large triangle and the small one are isosceles. because 2 of the 3 angles are equal.
Now are you ready for this? That means that BA = 10 because BA is opposite one of the 2 equal angles in the small triangle. So now you are ready to set up a proportion.
Proportion
AB / AC = AE/AD
Givens
AB = 10
AC = 18
AE = 8
AD = x + 8
Solution
Substitute the Givens into the Proportion.
10/18 = 8/(x + 8) Cross multiply
10(x + 8) = 8 * 18 Simplify both sides
10x + 80 = 144 Subtract 80 from both sides
10x + 80 - 80 = 144 - 80
10x = 64 Divide by 10
10x/10 = 64/10
Answer: x = 6.4

Answer:
m∠N = 85°
Step-by-step explanation:
Properties of a parallelogram
opposite sides are parallel and equal in lengthopposite angles are equalinterior angles that lie on the same side of the transversal are supplementary - their sum is 180°Therefore,
m∠M + m∠N = 180°
⇒ 95° + m∠N = 180°
⇒ m∠N = 180° - 95°
⇒ m∠N = 85°
--------------------------------------------------------------------------------------
Additional calculations
m∠M = m∠P = 95°
m∠N = m∠L = 85°
MN = LP
ML = NP

Using a two-tailed test with an alpha of 0.05, a research reports an obtained Z-score of -2. The researcher should reject the null
hypothesis.
True
False
Since the absolute value of the z-score is greater than the critical value, the statement is true.
When do we reject or do not reject the null hypothesis?For a two-tailed test:
If the absolute value of the test statistic is less than the critical value, we do not reject the null hypothesis.If it is more, we reject.The critical value for a two-tailed test with [tex]\alpha = 0.05[/tex] is of |z| = 1.96.
In this problem, we have that Z = -2, hence |Z| = 2, which is greater than the critical value, hence we reject the null hypothesis and the statement is True.

[tex]\boxed{\sf{x=\dfrac{13}{5}=2.6 }}[/tex]Step-by-step explanation:
To solve for x, you have to isolate it on one side of the equation.
First, subtract by 15 from both sides.
[tex]\sf{5x+15-15=28-15}[/tex]
Solve.
28-15=13
Rewrite the problem down.
5x=13
Divide by 5 from both sides.
[tex]\sf{\dfrac{5x}{5}=\dfrac{13}{5} }[/tex]
Solve.
You can also divide the numbers from left to right.
13/5=2.6
[tex]\boxed{\sf{x=\dfrac{13}{5}=2.6 }}[/tex]
Therefore, the correct answers is x=13/5=2.6.I hope this helps you! Let me know if my answer is wrong or not.
[tex]\rightarrow \sf 5x + 15 = 28[/tex]
[tex]\rightarrow \sf 5x + 15 -15= 28-15[/tex]
[tex]\rightarrow \sf 5x = 13[/tex]
[tex]\rightarrow \sf \dfrac{5x}{5} = \dfrac{13}{5}[/tex]
[tex]\rightarrow \sf x = \dfrac{13}{5}[/tex]
[tex]\rightarrow \sf x = 2\dfrac{3}{5}[/tex]

Leslie earned $12 Friday, $20 Saturday, and $56 Sunday selling bracelets. If she sold each bracelet for the same amount of money what is the most she could charge for each bracelet?
Answer:
$4
Step-by-step explanation:
For this, you want to find the greatest common factor
This basically means what number can be divided out of all of these.
So, you can find the factors for all of them and find which one appears in all three numbers and which is the greatest number
for 12:
1, 2, 3, 4, 6, 12
For 20:
1, 2, 4, 5, 10, 20
For 56:
1, 2, 4, 7, 8, 14, 28, 56
The numbers that appear in all of there are:
1, 2, and 4

Pls explain how u got the answer!
Answer:
D.
Step-by-step explanation:
We know that each centimeter is equal to 2.5 feet. The way I solved it was this.
We start with the 4cm. We can multiply 4×2.5, and that gives us 10 feet. We can do 8.5×2.5, and that will equal 21.25 feet. So the final and correct answer is D. 10 feet by 21.25 feet
