Answer:

B. An equilateral triangle is an isosceles triangle.

Step-by-step explanation:

We are given that if a triangle has atleast  two congruent sides , it is an isosceles triangle.

An isosceles triangle is that triangle in which two sides are congruent and two angles made by two congruent sides are congruent.

Now , we are given that an equilateral  triangle has three congruent sides .

We know that if a triangle is an equilateral triangle then it will have three congruent sides and three congruent angles.

If a triangle is an equilateral triangle then it will also an isosceles triangle because it is satisfied the property of an isosceles triangle.It means it will have two congruent sides and two congruent angles made by two congruent sides .Therefore, an equilateral triangle is an isosceles triangle.Hence, option B is true.

But

A. An isosceles triangle is an equilateral triangle . it is false because isosceles triangle have two congruent sides not three congruent sides therefore it can not be equilateral triangle. Hence, option A is false.

C. An isosceles triangle has three congruent sides.It is false statement because we know that  isosceles triangle have  only two congruent sides not three congruent sides. Therefore, option C is false.

D.An equilateral triangle has two congruent sides . It is false because we know that an equilateral triangle has three congruent sides not two.Therefore, option D is false.

10. At the end of the day, Mandy sold the rest of her hot dogs at her hot dog stand for half price. 50
vekshin1

Answer:

56

Step-by-step explanation:

Firstly, we know she sold 24 hot dogs at half price. We do not know the total number of hot dogs.

Secondly, we know that 30% of the hot dogs were sold at half of the price. This means 70% were sold at full price.

Now there are two approaches to this. I'm going to take the easier one.

What we are expressing mathematically is that 30% of a certain number equals 24. Let the total number of hot dogs she had that day at her stand be x.

This mean 30% of x = 24.

30/100 × x = 24

30x = 24× 100

30x = 2,400

x = 2,400/30 = 80.

This means she had a total of 80 hot dogs that day. Since we know the number she sold at half price, it's now easy to calculate the number she sold at full price.

This number now equals 80 - 24 = 56 hot dogs.

This mean Mandy sold 56 hot dogs at full price.

Subtract fractions with different denominators
Tems11 [23]

Answer:

\frac{10}{15}-\frac{2}{5}=\frac{4}{15}

Step-by-step explanation:

We know that

  • A fraction consists of two integers—one on the top, and one on the bottom.
  • The top one is numerator, the bottom one is denominator, and
  • These two numbers are separated by a line.

Let us consider two different fractions with different denominators

  • \frac{10}{15}
  • \frac{2}{5}

Lets subtract the two fractions

\frac{10}{15}-\frac{2}{5}\:\:\:\:

\mathrm{Cancel\:}\frac{10}{15}:\quad \frac{2}{3}

=\frac{2}{3}-\frac{2}{5}

\mathrm{Least\:Common\:Multiplier\:of\:}3,\:5:\quad 15

\mathrm{Adjust\:Fractions\:based\:on\:the\:LCM}

\mathrm{For}\:\frac{2}{3}:\:\mathrm{multiply\:the\:denominator\:and\:numerator\:by\:}\:5

\frac{2}{3}=\frac{2\cdot \:5}{3\cdot \:5}=\frac{10}{15}

\mathrm{For}\:\frac{2}{5}:\:\mathrm{multiply\:the\:denominator\:and\:numerator\:by\:}\:3

\frac{2}{5}=\frac{2\cdot \:3}{5\cdot \:3}=\frac{6}{15}

so

=\frac{10}{15}-\frac{6}{15}

\mathrm{Since\:the\:denominators\:are\:equal,\:combine\:the\:fractions}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}

=\frac{10-6}{15}

\mathrm{Subtract\:the\:numbers:}\:10-6=4

=\frac{4}{15}

Therefore,

\frac{10}{15}-\frac{2}{5}=\frac{4}{15}

Find the next two terms in the given sequence, then write it in recursive form. A.) {7,12,17,22,27,...} B.) { 3,7,15,31,63,...}​
iren [92.7K]

Answer:

A) a_n = 5n + 2

B) a_n = (2^(n + 1)) - 1

Step-by-step explanation:

A) The sequence is given as;

{7,12,17,22,27,...}

The differences are:

5,5,5,5.

This is an arithmetic sequence following the formula;

a_n = a_1 + (n - 1)d

d is 5

Thus;

a_n = a_1 + (n - 1)5

Now, a_1 = 7. Thus;

a_n = 7 + 5n - 5

a_n = 5n + 2

B) The sequence is given as;

{ 3,7,15,31,63,...}​

Now, let's write out the differences of this sequence:

Differences are:

4, 8, 16, 32

This shows that it is a geometric sequence with a common ratio of 2.

In the given sequence, a_1 = 3 and a_2 = 7 and a_3 = 15

Thus, a_2 = 2a_1 + 1

Also, a_(2 + 1) = 2a_2 + 1

Combining both equations, we can deduce that: a_(n + 1) = 2a_n + 1

Thus; a_n can be expressed as:

a_n = (2^(n + 1)) - 1
