The tens digit is 9 more than the ones digit

1 answer:

6 0

This number should be 10.

The tens digit the the 1st number on a two-digit number. Because the highest number you can go without creating a hundredths place is a 9, and the question says the ones-place (the last digit), this has to make this number 0. If it were to be 1 or anything higher, it would have to create a hundredths place if the rule of the question were to be followed.

Example:
If ones-place were 1, then following rule: 1+9 = 10
Your number would end up being 101 instead of a tenths place number.

I hope that made some sense somewhere!

Verify a÷(b+c)not equal(a÷b)+a÷c for each of the following values of a, b and c

just olya [345]

Answer:

a) and b) satisfied the condition of the given equation.

Step-by-step explanation:

Given: $\frac{a}{(b + c)}$ ≠ $\frac{a}{b}$ + $\frac{a}{c}$

Then,

$\frac{a}{(b + c)}$ ≠ $\frac{(ac + ab)}{bc}$

a) For a = 21, b = 4 and c = -2, then we have;

$\frac{21}{(4 + (-2))}$ ≠ $\frac{(21*-2 + 21*4)}{4*-2}$

$\frac{21}{4 - 2}$ ≠ $\frac{(-42 + 84)}{-8}$

$\frac{21}{2}$ ≠ $\frac{42}{-8}$

$\frac{21}{2}$ ≠ $-\frac{21}{4}$

Therefore the condition of the given equation is satisfied.

b) For a = 1, b = 10 and c = 1, then we have:

$\frac{1}{(10 + 1)}$ ≠ $\frac{(1*1 + 1*10)}{10*1}$

$\frac{1}{11}$ ≠ $\frac{(1 + 10)}{10}$

$\frac{1}{11}$ ≠ $\frac{11}{10}$

Therefore the condition of the given equation is satisfied.

An insect population triples every 4 months. If the population started out with 24 insects, how many

SpyIntel [72]

Answer:

After 16 months there will be a population of 1,944 insects.

Step-by-step explanation:

Since an insect population triples every 4 months, if the population started out with 24 insects, to determine how many insects would there be in 16 months, the following calculation must be performed:

X = 24 x 3 ^ (16/4)

X = 24 x 3 ^ 4

X = 1,944

Thus, after 16 months there will be a population of 1,944 insects.

Gelneren [198K]

Answer:

B. $6\sqrt2$

Step-by-step explanation:

Given:

The given triangle is an isosceles right angled triangle with the legs equal to 6 cm each and the hypotenuse is 'x' cm.

Applying Pythagoras theorem which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. Therefore,

$x^2=6^2+6^2\\x^2=36+36\\x^2=72\\x=\sqrt{72}\\x=\sqrt{36\times 2}\\x=\sqrt{36}\times \sqrt{2}\\x=6\sqrt2\ cm$

Therefore, the length of the hypotenuse is $x=6\sqrt2$ cm.

Hence, the option B is the correct one.
