Susie has read 52 pages of an 80- page book. What is the percentage of the pages that susie has not read?
Answers
Answer:
35%
Step-by-step explanation:
52/80=0.65
0.65x100=65
65% is the percent that she has read.
100%-65%= 35%
She has not read 35% of the pages.
Answer:
She hasn't read 35% of the book
Step-by-step explanation:
1st way: Since 80 pages represent 100%
52 pages represent 100 * 52 / 80 = 65% pages read
100 - 65 = 35 pages page not read.
2nd way: 80 - 52 = 28 pages not read
28 pages represent 100 * 28 / 80 = 35% pages not read

Need help with geometry problem
Answers
Answer:
y = [tex]6\sqrt{5}[/tex]
Step-by-step explanation:
x^2 + z^2 = 29^2
x^2 = y^2 + 9^2
y^2 + 20^2 = z^2
29^2 - z^2 = y^2 + 81 (equating for x^2 from eqn 1 and 2)
substitute 3rd eqn in 4th
29^2 - (y^2 + 20^2) = y^2 + 81
841 - y^2 - 400 = y^2 + 81
441 = 2y^2 + 81
360 = 2y^2
y^2 = 180
y = [tex]\sqrt{180}[/tex]
= [tex]\sqrt{36*5} \\[/tex]
y = [tex]6\sqrt{5}[/tex]
A country in South America exported 62% of the 315,000 bags of coffee beans they produced in a given year. How many bags did they export? Can someone please help me without a link to go to.
Answers
Answer:
195,300
Step-by-step explanation:
62 percent *315000 =
(62:100)*315000 =
(62*315000):100 =
19530000:100 = 195300
Now we have: 62 percent of 315000 = 195300
Question: What is 62 percent of 315000?
Percentage solution with steps:
Step 1: Our output value is 315000.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above,315000=100%.
Step 4: Similarly, x=62%.
Step 5: This results in a pair of simple equations:
315000=100%(1).
x=62%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
315000/x = 100/62%
Step 7: Again, the reciprocal of both sides gives
x/315000 = 62/100
x=195300
Therefore, 62% of 315000 is 195300

Step-by-step explanation:
Let's solve for h.
[tex]3h+g=5h-hg[/tex]
Step 1: Add [tex]gh[/tex] to both sides.
[tex]g+3h+gh=-gh+5h+gh[/tex]
[tex]gh+g+3h=5h[/tex]
Step 2: Add [tex]-5h[/tex] to both sides.
[tex]gh+g+3h+-5h=5h+-5h[/tex]
[tex]gh+g-2h=0[/tex]
Step 3: Add [tex]-g[/tex] to both sides.
[tex]gh+g-2h+-g=0+-g[/tex]
[tex]gh-2h=-g[/tex]
Step 4: Factor out the variable [tex]h[/tex].
[tex]h(g-2)=-g[/tex]
Step 5: Divide both sides by [tex]g-2[/tex].
[tex]\frac{h(g-2)}{g-2} =\frac{-g}{g-2}[/tex]
[tex]h=\frac{-g}{g-2}[/tex]

If an amount of $25,000 is deposited into a saving account at an interest rate 4%, compounded semi-annually, how long will it take to accumulate on this account $28,500? The function describing your balance is M(n) =25,000(1+0.04/2)^2n, where n is time in years. 20 points and WILL GIVE BRAINLIEST!
Answers
It will take 3.3 years to accumulate $28,500 on this account
According to the compound amount formula expressed as:
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
P is the principal = $25,000
A is the amount = $28,500
r is the rate in decimal = 4% = 0.04
n = 2 (semi annualy)
Substitute the given parameters into the formula as shown:
[tex]28,500=25,000(1+\frac{0.04}{2} )^{2t}\\1.14=(1+0.02)^{2t}\\1.14 = (1.02)^{2t}\\ln1.14 = 2tln1.02\\2t=\frac{ln1.14}{ln1.02}\\2t= \frac{0.13103}{0.01980}\\2t= 6.6177\\t = 3.30yrs[/tex]

What equation represents this sentence? 5 less than a number is 12. n−5=12 5=12−n 5=n−12 5−n=12
Answers
Answer:
n-5=12
This is the answer
The algebraic equation n - 5 = 12 represents the sentence " 5 less than a number is 12" and the solution of the equation is the value of variable n is 17.
What is Algebra?Algebra is the estimation of mathematical representations, while logic is the manipulation of those symbols.
The given statement is "5 less than a number is 12"
According to the given question, translate the phrase into an algebraic form :
⇒ n - 5 = 12
Thus, the algebraic equation n - 5 = 12 represents the sentence " 5 less than a number is 12"
Now the above equation solves for variable n,
⇒ n - 5 = 12
Add 5 to both sides of the above equation,
⇒ n = 12 + 5
⇒ n = 17
Therefore, the algebraic equation n - 5 = 12 represents the sentence " 5 less than a number is 12" and the solution of the equation is the value of variable n is 17.
