Answer:

10 cm

Step-by-step explanation:

$a^2=b^2+c^2$

$a^2=6^2+8^2$

$a^2=100$

$\sqrt{a^2}=\sqrt{100$

a=10

Answer:

c = 10

Explanation:

Use Pythagoras theorem: a² + b² = c²

where 'a' and 'b' are legs and 'c' is the hypotenuse (the longest side)

Here given: a = 8 cm, b = 6 cm, c = ?

Substituting values:

8² + 6² = c²

c² = 64 + 36

c² = 100

c = √100

c = 10

Use the distributive property to write an expression that is equivalent to: 3(x + 5)

lana [24]

Answer:

3x=15

Step-by-step explanation:

Here's what I found on google about the distributive property-

To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Now for the math-

3(x+5)

distribute the numbers- 3(x)+3(5)

solve- 3*5=15

3x+15

Please help me with circle questions below

IRINA_888 [86]

For first question, What is approximate value of "......" this part is missing so please write whose approximate value question is asking to find

For second question we have to find $tan\Theta$

In right triangle ABC as show in attachment,

$tan\Theta = \frac{opposite side}{adjacent side} = \frac{AB}{BC}$ ----(1)

Now AB is given by distance of point A from x axis which will be given by its y - coordinate. So $AB = \frac{1}{2}$

Similarly BC is the distance of point A from y axis (horizontal distance ) and that will be given by x coordinate of A. So $BC = \frac{\sqrt{3}}{2}$

Plug these values in equation (1)

$tan\Theta = \frac{AB}{BC} = \frac{\frac{1}{2}}{\frac{\sqrt{3}}{2}}$

To divide fractions we flip (reciprocal ) bottom fraction and multiply it to top fraction as shown

$tan\Theta = \frac{1}{2} \times \frac{2}{\sqrt{3}}$

Now 2 in top and bottom cancels out so we are left with

$tan\Theta = \frac{1}{\sqrt{3}}$

so thats the final answer for $tan\Theta$

in a group of people for every 20 people 7 of them have blue eyes a) write the ratio of the number of people with blue eyes to t

bazaltina [42]

Answer:

a) 7 : 20

b)There will be 35 people with blue eye

Step-by-step explanation:

a)

This question is asking you the ratio of the number of people with blue eyes to the total number of people.

So seven people with blue eyes to the total number of 20 people.

7 : 20

b)

you got the ratio 7 : 20, this also means that there will be 7 people with blue eyes in every 20 people.

so you use 100 divides by 20, you will get the number five, this means there are 5 groups of 20 in 100 people.

so then you use 5 times 7, then you got the number 35.

That means, there are 35 people with blue eyes in 100 people.
