Five less than twice the value of a number is equal to three times the quantity of four more than ½ the number. What is the number?
Step-by-step explanation:
(2x-5) = 3(4+x/2) then solve for x.
2x-5 = 12 + (3/2)x
2x-(3/2)x = 17
x/2 = 17
x=34
Checking the left side, (2x-5) = 2(34) - 5 = 63.
Checking the right side, 3(4+(34/2)) = 3(4+17) = 3(21) = 63.
The ratio of cats to dogs is 3 : 7.
12 dogs escaped and the ratio is now 3 : 4.
Work out how many animals there were at the beginning.
Given:
The ratio of cats to dogs is 3:7.
12 dogs escaped and the ratio is now 3 : 4.
To find:
The total number of animal at the beginning.
Solution:
Let the number of cats and dogs at the beginning are 3x and 7x respectively.
12 dogs escaped. So, the remaining number of dogs is (7x-12).
New ratio of cats and dogs is 3:4.
[tex]\dfrac{3x}{7x-12}=\dfrac{3}{4}[/tex]
[tex]4(3x)=3(7x-12)[/tex]
[tex]12x=21x-36[/tex]
[tex]12x-21x=-36[/tex]
[tex]-9x=-36[/tex]
Divide both sides by -9.
[tex]\dfrac{-9x}{-9}=\dfrac{-36}{-9}[/tex]
[tex]x=4[/tex]
Now, the total number of animals at the beginning is
[tex]Total=3x+7x[/tex]
[tex]Total=10x[/tex]
[tex]Total=10(4)[/tex]
[tex]Total=40[/tex]
Therefore, the total number of animals at the beginning is 40.

hii im sorry to be a burden but could someone please help me with this problem it has to do with the pythagorean theorem :p
Answer:
Step-by-step explanation:
10 inches
Answer:
68.5 inches
Step-by-step explanation:
The pythagorean theorem is a^2+b^2 = c^2
In this case, a = 60, b = 33, and we are looking for c, so this is how you do it:
60^2 + 33^2 = 3600 + 1089 = 4689
sqrt(4689) = 68.47627326...
Rounded to the nearest tenth is 68.5!
which expression is equivalent to the given expression?
Answer:
4ln x +ln 3-lnx
4ln x -ln x+ln3
3ln x+ln 3
ln(3x+3)is equivalent.
There are two numbers. The larger number is five more than the smaller
number. Three times the smaller number increased by the larger number
equals 147. Find the two numbers.
please help!!!! im in a test!!!!!!!!
Answer:
35.5 + 40.5
Step-by-step explanation:
smaller number = x
large number = x +5
3x + x +5 = 147
4 x +5 = 147
4x = 142
x = 35.5
x +5 = 40.5
Ariane borrows $300 on a 5−year loan. She is charged 5% simple interest per year. How much interest is she charged for 5 years? What is the total amount she has to pay back?
Answer:
Interest = $75
Total to pay back = $375
Step-by-step explanation:
The total amount she will have to pay back is found by the formula:
= Amount borrowed * (1 + rate * years)
= 300 * ( 1 + 5% * 5)
= $375
The interest is therefore:
= Amount to be paid back - Amount borrowed
= 375 - 300
= $75

Does association between variables mean that there is a cause-and-effect
relationship? Why or why not? Give an example.
Answer:
Yes
Step-by-step explanation:
Two variables may be associated without a causal relationship. For example, there is a statistical association between the number of people who drowned by falling into a pool and the number of films Nicolas Cage appeared in in a given year. However, there is obviously no causal relationship.

In a bag, Bag C, the ratio of red counters to yellow counters is 3 : 4.
If 3 of the red counters are removed from Bag C, the ratio of red counters
to yellow counters is 3 : 5.
How many yellow counters are in Bag C?
Answer:
20
Step-by-step explanation:
The ratio of red : yellow is 3 : 4 = 3x : 4x ( x is a multiplier )
If 3 red counters are removed then
red : yellow = 3x - 3 : 4x = 3 : 5
Expressing in fractional form
[tex]\frac{3x-3}{4x}[/tex] = [tex]\frac{3}{5}[/tex] ( cross- multiply )
5(3x - 3) = 12x
15x - 15 = 12x ( subtract 12x from both sides )
3x - 15 = 0 ( add 15 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
Then
number of yellow counters = 4x = 4 × 5 = 20

csc^-1 4.25 to degrees
9514 1404 393
Answer:
13.609°
Step-by-step explanation:
The csc^-1 function is the arccosecant function. It gives the angle whose cosecant is given. If we let A represent that angle, your statement is ...
A = csc^-1(4.25)
It is used to solve the relation ...
4.25 = csc(A)
__
Some calculators can give you the value directly (see attached). Most cannot. In any event, you need to make sure the angle mode for the calculator is set to degrees.
When your calculator does not have the csc^-1 function, you can make use of the trig identity ...
csc(x) = 1/sin(x)
In the above equation, this becomes ...
4.25 = 1/sin(A)
sin(A) = 1/4.25 . . . . . solve for sin(A)
All scientific and graphing calculators will have the inverse sine (arcsine) function.
A = sin^-1(1/4.25)
A ≈ 13.609° . . . . . . . calculator mode in Degrees
_____
Additional comment
For inverse functions, especially inverse trig functions, I find it useful to read them as ...
csc^-1(x) ⇒ "the angle whose cosecant is x"
sin^-1(x) ⇒ "the angle whose sine is x"
This reminds me that the value it gives is an angle (degrees or radians), and the argument it takes is a pure number (one with no units).

A cube with a volume of 64 cubic meters is scaled by a factor of 5. What is the volume of the
modified cube in cubic meters? (Note: do not include the units in your answer.)
Clear
X Incorrect. When the sides of the cube are scaled by a factor of k = 5) the volume increases
by a factor of k = 52 = 125. Here, the new volume is 64 cubic meters 125 = 8,000 cubic
meters. Enter the correct answer
