Helpppppppppppppppppppppppppppppppppppppp

katrin [286]

firts lets see how many dollars she has

192 divided by 4 is 48 so she currently has 48 dollars.

and she puts in 2 quarters daily

so lets see how much she need to earn

75 - 48 is 27

lets see how many quarters she need to have 27 dollars 27 x 4 is 180

now lets divide 180 by two because shes giving two everyday. 180 divided by 2 is 54 so if she kept adding two quarters everyday it would take her 54 days to get the rest of the money she need to by and iPod.

i dont know if this helped or not but i solved it

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

Triangle ABC is formed by two parallel lines and two other intersecting lines. Find the measure of each angle A, B, and of the t

Mamont248 [21]

Answer:

A = 61°

B = 72°

C = 47°

Step-by-step explanation:

Well, first of all, we can see that:

$61^{\circ}+47^{\circ}+B^{\circ}=180^{\circ}$

So, we can find angle B.

$B=180^{\circ}-47^{\circ}-61^{\circ}$

$B=72^{\circ}$

Now, we can see to that angle C is just 47°

Finally, we know that the sum of all angles in a triangle is 180°, so we have:

$B+A+C=180^{\circ}$

$A=180^{\circ}-47^{\circ}-72^{\circ}$

$A=61^{\circ}$

I hope it helps you!

Can someone help to show the steps and answer the question in the image please?

Fudgin [204]

Answer:

Step-by-step explanation:

You just need to find the volumes of both container and soap and divide them. So;

Volume of Soap = 15cm * 8cm * 6cm = 720 cm^3

Volume of Container = 165cm * 40cm * 96cm = 633600 cm^3

Dividing them gives = 633600 cm^3 / 720 cm^3 = 880

Answer is B.
