Step-by-step explanation:

Let's set Huilan's age to h and Thomas's age to t.

Since Huilan is 13 years younger than Thomas, we can write:

h = t - 13

The sum of both their ages is 41, so let's combine the variables h and t together.

h + t = 41

We said that h = t - 13, so substitute this value into the equation.

(t - 13) + t = 41

Combine like terms.

2t - 13 = 41

Add 13 to both sides of the equation.

2t = 54

Divide both sides of the equation by 2.

t = 27

Thomas's age is 27 years old.

Thank you L for helping me with this question :)

A batch consists of 12 defective coils and 88 good ones. Find the probability of getting two good coils when two coils are rando

Allushta [10]

Answer:

The probability of getting two good coils when two coils are randomly selected if the first selection is replaced before the second is made is 0.7744

Solution:

Total number of coils = number of good coils + defective coils = 88 + 12 = 100

p(getting two good coils for two selection) = p( getting 2 good coils for first selection ) $\times$ p(getting 2 good coils for second selection)

p(first selection) = p(second selection) = $\frac{\text { number of good coils }}{\text { total number of coils }}$

Hence, p(getting 2 good coil for two selection) = $\frac{88}{100} \times \frac{88}{100} =\bold{0.7744}$

Which of the below is not one of the properties of logarithms?

MrRa [10]

Answer:

option-B

Step-by-step explanation:

we know that

Sum rule of logarithm:

$log(a)+log(b)=log(a\times b)$

which is same as

the log of a product (ab) is equal to the addition of log a nad log b

Subtraction rule of logarithm:

$log(a)-log(b)=log(\frac{a}{b} )$

which is same as

the log of the quotient of a and b is equal to the log of a minus the log of b

Exponent rule of logarithm:

$log(a^b)=blog(a)$

which is same as

the log of the quantity a raised to b is equal to the product of b and the log of a

so,

option-B is not correct

marissa [1.9K]

Since Maria is going to put a trim around a triangle-shaped banner with 22 inches long per side, this means that for the banner, it has a total length of 66 inches. 66 inches would be equal to 5.5 foot. This means that the total length of the trim from the start is 7 foot. Hope this helps.
