Answer:
Yes they are equivalent.
Step-by-step explanation:
Find the least common denominator or LCM of the two denominators:
LCM of 4 and 20 is 20
Next, find the equivalent fraction of both fractional numbers with denominator 20
For the 1st fraction, since 4 × 5 = 20,
3
4
=
3 × 5
4 × 5
=

Likewise, for the 2nd fraction, since 20 × 1 = 20,
15
20
=
15 × 1
20 × 1
=
15
20
Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction
15

=

or

=

20
Yes, we can say that the ratio 15 : 20 and 3 : 4 are equivalent.
What are ratios?The ratio is the number that can be used to express one quantity as a fraction of the other ones. The two numbers in a ratio can only be compared when they have the same unit.
Equivalent ratios are the ratios that are the same when we compare them.
Therefore, for ratios of 15 : 20 and 3 : 4, for them to be equivalent, they must have thesame value.
15 : 20 = 15/20
divide through by 5
= 3/4 = 3 :4
Therefore , we can say that ratios 15 : 20 and 3 : 4 are equivalent.

[tex]\frac{-1}{a+b}[/tex]
Step-by-step explanation:
Let's solve for x.
Ax+bx−3=−4
Step 1: Add 3 to both sides.
Ax+bx−3+3=−4+3
ax+bx=−1
Step 2: Factor out variable x.
X(a+b)=−1
Step 3: Divide both sides by a+b.
[tex]\frac{x(a+b)}{a+b} =\frac{-1}{a+b}[/tex]

each day pierrie gets up at 7;00 and goes to bed at 22;00 what percentage of the day is he is bed
Answer:
37.5%
Step-by-step explanation:
Okay, so he gets up at 7:00. He goes to bed at 10:00. So, 10, into 12 thats two hours and then 7 thats another seven hours, so 9 hours he is in bed. Theres 24 hours in a day so thats 9 hours out of the day. If we turned that into a percentage that would be %62.5 hours in a day he is not sleeping, and 100 - 62.5 would be 37.5.
The answer is 37.5
Factor out the coefficient of the variable term.
The expression
3/8d + 3/4
Factored is
Answer:
For this case we have the following expression:
(3/8)d + 3/4(3/8)d+3/4
We must factor the term that accompanies the variable.
We have then:
(3/8) (d + (3/4) * (8/3))(3/8)(d+(3/4)∗(8/3))
Rewriting the expression we have:
(3/8) (d + 8/4) (3/8) (d + 2)(3/8)(d+8/4)(3/8)(d+2)
We're going to check the result. To do this, we multiply the term 3/8 for each term within the parenthesis:
(3/8) d + 2 (3/8)(3/8)d+2(3/8)
Rewriting:
(3/8) d + 3/4(3/8)d+3/4
The factorization is correct.
Answer:(3/8) (d + 2)

find the mean (average) of the data set below? 2/4 18/5 28/10 5/20
Step-by-step explanation:
sum of numbers divided by how many numbers there are.
(2/4 + 18/5 + 28/10 + 5/20)/4
we bring all fractions to .../20, as 20 is the smallest common multiple of all denominators. and then we can easily sum them all up.
so,
(10/20 + 72/20 + 56/20 + 5/20)/4 =
143/20 / 4 = 143/20 × 1/4 =
= 143/80 is the mean or average

A town's population is currently 5,000. If the population doubles every 27 years, what will the
population be 54 years from now?
Answer:
20000
Step-by-step explanation: If it doubles every 27 years and its asking if 54 years had passed then it would be 5000*4 which is 20,000
Brainliest is appreciated
Answer: 20,000
Step-by-step explanation:
Because the population doubles every 27 years, the population will double twice since 54/27 = 2
5,000 * 2 = 10,000
10,000 * 2 = 20,000
Alternatively you can add instead of multiplying
5,000 + 5,000 = 10,000
10,000 + 10,000 = 20,000

==================================================
Explanation:
Given a triangle with sides a and b, the third side c is bounded by this compound inequality
b-a < c < b+a
where a < b
--------
In this case, a = 16 and b = 26, so
b-a < c < b+a
26-16 < x < 26+16
10 < x < 42
I'm using a version of the triangle inequality theorem.
This unknown third side is between 10 cm and 42 cm. The third side cannot equal 10 nor can it equal 42.
how to simplify 4a-3b+6a
Step-by-step explanation:
very simple : the terms with the same base (either a specific number or a variable with the same exponent, or a function ...) can be combined.
4a - 3b + 6a
which terms here have the same base ?
ah, 4a and 6a refer to the same variable (and with the same exponent : 1, as a = a¹).
therefore, I can combine them :
4a + 6a = a×(4+6) = a×10 or simply 10a
so the result is
10a - 3b
You have agreed to borrow $50 and after six months you pay back $58. How much interest are you paying? What is the interest rate?
Answer:
interest: 8 interest rate: 16
Step-by-step explanation:
the interest is 8$ since you payed 8$ extra, the interest rate can be counted in another way but I forgot it. So 50 is 100%, you divide it by 100 and get 0.5. then you take 8/0.5 which means how many percent there is in 8 which is 16.
This can be solved much easier if you multiply by 2. you borrow 100 and get 116 in return. both interest and interest rate is 16
The interest is $8 and rate of interest is 16%.
What is interest?Using the interest rate formula, we get the interest rate, which is the percentage of the principal amount, charged by the lender or bank to the borrower for the use of its assets or money for a specific time period. The interest rate formula is
Interest Rate = (Simple Interest × 100)/(Principal × Time).
Given:
Interest = $58 - $50 = $8
Time = 6 months = 1/2 hours
Principal = $50
rate = ?
Thus, the rate of interest
= 8 x 100 / 50
=800 /50
= 16%
Hence, the interest is $8 and rate of interest is 16%.
