The smallest square number which can be divisible by 11 and 5

Elena L [17]

Answer:

3025

Step-by-step explanation:

let's look at it in this concept.

For a number to be divisible by 11 and 5. it must be a multiple of the LCM of 11 and 5.

LCM of 11 and 5=55

therefore the number is 55x, where x is a positive integer.

it is a said that the number is a perfect square

therefore the square root of 55x must be an integer.

$\sqrt{55x} = \sqrt{5 \times 11 \times x}$

the smallest value of x to make 55x a perfect square is....

$x = 11 \times 5 = 55$

Therefore the number is.... .

$55x = 55(55) = 3025$

sweet right

Hello whats is the size of the angle

Gennadij [26K]

Answer:

x = 65°

Step-by-step explanation:

The interior angle of the triangle and 140° are adjacent and supplementary, thus

interior angle = 180° - 140° = 40°

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

105° is an exterior angle of the triangle, thus

x + 40° = 105° ( subtract 40° from both sides )

x = 65°

the table shows ingredients needed to make 1 batch of fruit salad. Mr. Weakland has enough ingredients to make 2 1/2 batches of

Juli2301 [7.4K]

The number of cups of fruit salad that will be in each container is; 3³/₄ cups of fruit salad

<h3>How to divide fractions?</h3>

We are given the table showing the amount of cups of each ingredient as attached.

From the table we see that;

Amount of cups of Pineapple = 2³/₄

Amount of cups of Strawberries = 2¹/₂

Amount of cups of Bananas = 1¹/₂

Amount of cups of Blueberries = 2¹/₄

Now, converting each of the given fractions to improper fractions gives;

11/4, 5/2, 3/2, 9/2

Summing up all the fractions will give us;

11/4 + 5/2 + 3/2 + 9/2

(1/4)(11 + 10 + 6 + 18) = 45/4

Now, since this total amount will be divided by 3, we will have;

45/4 ÷ 3

= 45/4 * 1/3

= 15/4 = 3³/₄ cups of fruit salad
