In a group of 26 children, 12 are girls.....so this means that : (26 - 12) = 14 are boys.
so there are 12 girls and 14 boys
so the ratio of girls to boys is 12/14 which reduces to 6/7 <=

26 - 12 = 14 boys

girls : boys = 12 : 14 = 6 : 7

A rectangle with a length of 6 inches and a width of 1 foot has a perimeter of 14 inches.
Pachacha [2.7K]
The length is 6 inches.
The width is 1 foot = 12 inches.

The perimeter is  (6 + 12 + 6 + 12) = 36 inches (3 feet) .

"14 inches" is false.

Hi! can someone please help? i added a pic so that u can see what i need help on. hopefully it helps

Answer:

I'm pretty sure that the answers would go, Wrong, increased, 9 1/2 points, 6 5/8 points, dropped, 12 3/4 points.

Step-by-step explanation:

The reason why it would be wrong is because the amount of points lost was less than the total amount of points gained.

In week one and two the company gained 9 1/2 points and 6 5/8 points. When you add them together, you get 16 1/8 points.

In week three the company lost 12 3/4 points. If you multiply the fraction to change the denominator to 8, the mixed fraction becomes 12 6/8.

16 1/8 - 12 6/8 = 3 3/8

As you can see, there are still points left over.

In the fourth week, they ended up losing all of their points and then some more, but from my understanding it's just asking about the third week.

Hope that this helps!

population growth problem: the deer population in georgia was 450,000 in 2010, and the population doubles every 5 years. in what
VikaD [51]
We know that in 2020 the population of deer will be 900,000 based on the given numbers. In another 5 years the population will be over 1 million (1,350,000) in order to calculate when it will reach 1 million we need to see how much growth is gained per year. I believe to obtain that information we will need to divide 450,000 by 5 that equals 90,000 a year. So if I’m 2020 the population of deer will be 900,000 than add 90,000 until you reach your 1 million marker. In this case 2021 would be 990,000 thousand so 2022 would be 1,080,000. So your answer should be year 2022. Hope that helps.

Calculate the area of the regular pentagon below: A regular pentagon with side length of 11.8 inches and dotted line from center
vlada-n [284]

Answer:

Area of regular pentagon is 238.95 square inches.

Step-by-step explanation:

Given a regular pentagon with side length of 11.8 inches and dotted line from center to middle of side of 8.1 inches.

we know a regular polygon divides into 5 congruent triangles.

Side of pentagon i.e base of one triangle is 11.8 inches.

Also, distance from center to middle of side which is height of triangle is 8.1 inches.

Area of 1 triangle= \frac{1}{2}\times base\times height

                           =  \frac{1}{2}\times 11.8\times 8.1

                           = 47.79 sq inches.

Area of regular pentagon=area of 5 congruent triangles= 5\times 47.79=238.95 sq inches.
