Answer:
5%
Step-by-step explanation:
Look at the values from high school athletes (the first row of numbers) to the values of college student athletes (the second row). Since we are only looking for male percentages, ignore the women's basketball
Take any of the college values, and divide it by the high school values. After this, multiply by 100 to get a percentage
Example, 56500 ÷ 983600 = 0.05
0.05 * 100 = 5%
You will get 5% for all males sports in this table
Step-by-step explanation:
there are 2 similar triangles : ABE and DCE
that means they have the same angles, and the scaling factor from one triangle to the other is the same for every side.
and that means that
DE/AE = EC/BE (= DC/AB)
we know that
AE = AD + DE
BE = BC + EC
a.
so, we have actually
DE/(AD+DE) = EC/(BC+EC)
DE/(10+DE) = 8/(2+8) = 8/10 = 4/5
DE = 4(10+DE)/5
5DE = 4(10+DE) = 40 + 4DE
DE = 40 cm
b.
AD/DE = 3/5
BC/EC must be 3/5 too.
15/EC = 3/5
15 = 3EC/5
75 = 3EC
EC = 25 cm
The digit in the hundreds place has a value 10 times as great as the value in the tens place. The digit in the tens place has 1/10 the value of the digit in the hundred place
<h3>What is place value?</h3>
Place value is simply the value of each digit in a number.
For instance:
- The 3 in 350 represents 3 hundreds, or 300
- The 5 in 5,006 represents 5 thousands, or 5,000.
It is important to note that place value is the value represented by a digit in a number on the basis of its position in the number or figure.
We can deduce the following:
- The digit in the hundreds place has a value 10 times as great as the value in the tens place
- The place value of a digit at the hundredths place is 1/10 times the same digit at the tenths place
Thus, the digit in the hundreds place has a value 10 times as great as the value in the tens place. The digit in the tens place has 1/10 the value of the digit in the hundred place

Answer:
peanut butter cookies:8
sugar cookies:2
chocolate chip cookies:5
ratio: 4:1:2.5
Step-by-step explanation:
x=peanut butter cookies
y=sugar cookies
a=chocolate chip cookies
40=2x+3y+3.6a
15=x+y+a
x=a+3
15=(a+3)+y+a
y=12-2a
40=2(a+3)+3(12-2a)+3.6a
a=5
x=8
y=2
