Given:
[tex]\to 5c + d = c+ 4d[/tex]
To find:
c:d=?
Solution:
\to 5c + d = c+ 4d
simulating the identical terms:
[tex]\to 5c -c = 4d-d\\\\\to 4c = 3d\\\\\to \frac{c}{d} = \frac{3}{4}\\\\\therefore\\\to c:d= 3:4[/tex]
so, the ratio is 3:4

. If A = P + I, find l, when A= 4500 and P= 3750.
Answer:
Step-by-step explanation:
A = P + I
Putting values in the equation
4500 = 3750 + I
4500 / 3750 = I
1.2 = I
Answer:
I=750
Step-by-step explanation:
soln ,
here ,
A=4500
P=3750
I=?
Now,
A=P+I
or,4500=3750+I
or,I=4500-3750
•°•I=750

Plz very much help
last week, Haley scored 15 points. Haley increased her points 20% during her game this week compared to last week. How many points did she score this week?
Answer:
18
Step-by-step explanation:
15 + 20% = 18
If Hailey increased her points by 20%, she would score 18 points this week. Therefore, what we need to do is to multiply 15 by 0.20. How did we get 0.20? Well, we divided 20 by 100 to get 0.20. Anyway, once we have multiplied 15 by 0.20, we get 3. However, this answer would not be logical because she increased her points by 20% - we are going up and not down. So, we add 15 and 3 together to get a total of 18 points scored.

A city has a 5% sales tax.
A book costs $32.55 after tax.
How much did it cost before tax?
*please answer quick and tell me how you did it*
Answer: $30.92
Step-by-step explanation:
First step is to turn 5% into a decimal so that you can use it easier in a math sentence -- 0.05
Next, find out what 5% of $32.55 is by multiplying
0.05 x 32.55
= 1.6275
Round to the nearest cent because we don't use anything smaller than a cent when we are talking about money.
= $1.63
This is the amount of tax included in the price of $32.55
If we want to know what it the book cost before tax we simply take the tax off.
$32.55 - $1.63
= $30.92
Hope that helps :)

Determine the dimensions of a rectangular solid (with a square base) with maximum volume if its surface area is 529 square meters. Round each dimension to 4 decimal places
Answer:
[tex]x=23/\sqrt{6}[/tex],
[tex]y= \frac{23}{6\sqrt{6}}[/tex]
Step-by-step explanation:
From the question we are told that
Surface area is 529 square meters
Generally the dimensions of the cuboid
[tex]v=x^y[/tex]
[tex]D=4xy+2x^2 =529[/tex]
[tex]V=x^29(\frac{529-6x^2}{4x})[/tex]
[tex]V' =529-6x^2/4[/tex]
[tex]v'=0[/tex]
Therefore
[tex]529=6x^2[/tex]
[tex]x=\sqrt{\frac{529}{6} }[/tex]
[tex]x=23/\sqrt{6}[/tex]
Mathematically
[tex]v''=\frac{12x}{4}[/tex]
[tex]v''=-3\frac{23}{\sqrt{6} }<0[/tex]
[tex]y= \frac{529-2*(\frac{529}{6} }{4*\frac{23}{\sqrt{6} } }[/tex]
[tex]y= \frac{23}{6\sqrt{6}}[/tex]
Therefore
[tex]x=23/\sqrt{6}[/tex]
and
[tex]y= \frac{23}{6\sqrt{6}}[/tex]
Value of x in the equation 2(x+3)=4(x-1)?
Answer:
x = 5
Step-by-step explanation:
In this question, you would solve for x.
Solve:
2(x + 3) = 4(x - 1)
Use the distributive property.
2x + 6 = 4x - 4
Subtract 4x from both sides.
-2x + 6 = -4
Subtract 6 from both sides.
-2x = -10
Divide both sides by -2
x = 5
The value of x is 5.

HURRY PLEAASEEE. 2x2 – 13x + 24 = 3
Answer:
7/2 and 3
Step-by-step explanation:
using quadratic formula
{-(-13) +- √(-13)^2 - 4(2)(21) } /2(2)
-(-13)+1 / 4 = 7/2
-(-13)-1 / 4 = 3
Answer: x = 7/2 and 3
Step-by-step explanation: Rewrite and factor
2x² —13x + 21 = 0
(2x - 7)(x - 3) = 0
2x - 7 = 0. x = 7/2
x - 3 = 0 x = 3

Which of the following statements is correct? Group of answer choices For day-to-day business data analysis, most firms rely on a large staff of expert statisticians. A statistical test result that is significant also has practical importance. A parameter is a measure that is calculated from a sample. Statistics is the science of believability.
Answer:
Step-by-step explanation:
From the answer choices available the answer that is correct is that for day-to-day business data analysis, most firms rely on a large staff of expert statisticians. This is because on a daily basis firms receive large sets of data from all of their business movements, therefore a large staff of highly experienced individuals is needed in order to handle and document all of these numbers carefully so that no mistakes are made. The smallest mistake in the firm's financial accounts can lead to a very costly loss for the company.
