Girls to boys at concert 2:7 . 250 more girls than boys, how many boys

SIZIF [17.4K]

The Girls:Boys ratio of 7:2 means that there are 7 girls for every boy.
As there are 250 more girls this relates to the 7-2 part of the ratio.
We can then divide 250 by 5 and multiply by 2 to get the number of boys as 100 boys

Can someone please answer this with steps

ivanzaharov [21]

1) Put all equations together and add them up to equal 180. Triangle's angles add up to 180°

EX) (x+10)+(3x-5)+x=180

2)Combine like terms.

EX) (5x+5)=180

3) Subtract 5 to both sides

EX) 5x=175

4) Divide both sides by 5.

EX) x=35

What are the lengths of sides A and B of a right triangle if the hypotenuse is equal to 1.2 cm and the interior angles are 60 de

Natali5045456 [20]

We have been given that the hypotenuse of a right triangle is equal to 1.2 cm and the interior angles are 60 degrees, 30 degrees, and 90 degrees.

We know that hypotenuse corresponds to 90 degrees angles.

We also know that the hypotenuse is equal to twice the length of the shorter leg and shorter leg is the opposite side to 30 degree angle.

To find the length of shorter leg, we will divide length of hypotenuse by 2.

$\text{Side corresponding to 30 degree angle}=\frac{1.2\text{ cm}}{2}$

$\text{Side corresponding to 30 degree angle}=0.6\text{ cm}$

Therefore, length of shorter leg is 0.6 cm.

We know that the longer leg, which is across from the 60 degree angle, is equal to multiplying the shorter leg by $\sqrt{3}$ .

$\text{Side corresponding to 60 degree angle}=0.6\text{ cm}\times \sqrt{3}$

$\text{Side corresponding to 60 degree angle}=1.039230\text{ cm}$

$\text{Side corresponding to 60 degree angle}\approx 1.04\text{ cm}$

Therefore, length of longer leg is approximately 01.04 cm.

Answer:

I think answer number 1 and number 4

Step-by-step explanation:

to find the perimeter you add all the sides together, there are 4 sides in the square so it will be 2+2+2+2 which will give you 8 and you can also multiply 2 by the 4 sides which will also give you 8
