A chess team has 26 members. However, only 16 members attended the last meeting: half of the girls attended but all of the boys attended. How many boys are on the chess team?

Answers

Answer 1

Answer:

6 boys

Step-by-step explanation:

if all the boys(x) were at the meeting but only half the (y), you would have two equations : x+y=26 and x+y/2 = 16. Solving the system gives you 6 boys 20 girls.

Problem 4
You have to assume something or it is unsolvable.
We will assume that the triangle is divided into 2 smaller right triangles. They will be subject to a^2 + b^2 = c^2
a = 32/2 = 16
b = h
c = 20
20^2 = 16^2 + h^2
400 = 256 + h^2 Subtract 256
400 - 256 = h^2
144 = h^2
h = sqrt(144)
h = 12

Now we can find the area.
h = 12
base = b = 32

Area = 1/2 * b * h
Area = 1/2 * 32 * 12
Area = 192 square inches.

Problem 5
Same assumption. Same method.
a^2 + b^2 = c^2
c = 25
b = 7
h = ???
h^2 + 7^2 = 25^2
h^2 + 49 = 625
h^2 = 625 - 49
h^2 = 576
h = sqrt(576)
h = 24

Area = 1/2 Base * h
base = 2*7
base = b = 14

Area = 1/2 * 14 * 24
Area = 168 <<<< answer.

Answers

those are just repeating equivalent decimals

Final answer:

The decimal 0.5 converts to the fraction 1/2 and the decimal 0.7 converts to the fraction 7/10.

Explanation:

To convert the decimal 0.5 and 0.7 into fractions, we use the definition of a decimal. A decimal is a representation of a fraction in terms where we have a power of 10 in the denominator. For instance:

To convert 0.5 into a fraction, we can think of it as 0.5/1 which equals to 5/10 or simplifies to 1/2. Converting 0.7 into a fraction, would give us 0.7/1 which is equal to 7/10.

So, 0.5 as a decimal is 1/2 as a fraction and 0.7 as a decimal is 7/10 as a fraction.

hope it helps

Answer: [tex]\dfrac{1}{10}[/tex]

Step-by-step explanation:

Given : Number of yellow Skirt Number =5

Total skirt = [tex]5+8+4+3=20[/tex]

The probability that she will select a yellow skirt will be :_

[tex]\dfrac{5}{20}=\dfrac{1}{5}[/tex]

Total faces in coin=2

Number of tails = 1

The probability that the coin will land tails up :-

[tex]\dfrac{1}{2}[/tex]

Since ,both events are independent , then the probability that she will select a yellow skirt and that the coin will land tails up is given by :-

[tex]\dfrac{1}{5}\dfrac{1}{2}=\dfrac{1}{10}[/tex]

I don't quite know how to do this, so if someone could guide me through it that would be nice..!

Answers

The mean of the ages of Doctor 1's patients is 13.54 and the median is 15. The mean of the ages of Doctor 2's patients is 16 and the median is 19.

Explanation:
The mean is found by adding together all of the data points and then dividing by the number of data points. For Doctor 1, (32+20+22+29+15+17+18+1+1+2+3+7+9)/13 = 176/13 = 13.54.

For Doctor 2, (35+20+20+22+23+26+13+17+2+2+3+9)/12 = 192/12 = 16.

The median is the middle number in the data set after it has been ordered from least to greatest. The stem-and-leaf plot organizes it, so we find the middle value.

For Doctor 1, 15 is in the middle.

For Doctor 2, the middle is between 26 and 13: (26+13)/2 = 39/2 = 19.5

Answer:

The mean of the ages of Doctor 1's patients is 13.54 and the median is 15. The mean of the ages of Doctor 2's patients is 16 and the median is 19.

What are the ratio and proportion?

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b, will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

The ratio is the division and the ratio can be bigger than the amount which is put on the ratio or the ratio could be smaller than the amount which is put on the ratio. It depends upon whether the numerator is big or small than the denomintor.

Given the condition in the question let's suppose the number is x then

seven-time is 7x and 5 means 7x + 5.

Similarly -2 times means -2x and 11 means -2x + 11 hence (7x +5 )/(-2x+11) will be correct answer.

It took Yuik (1/6) of a hour to water get flowers and (4/6) of an hour to weed her garden. What fraction of an hour did Yuik work in her yard

Answers

Yuki worked in her yard for 5/6 of an hour (or 50 minutes). 1/6 + 4/6 = 5/6, because you don’t change the denominator.

The required fraction of an hour is 5/6 Yuik work in her yard.

What is the fraction?

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

It took Yuik (1/6) of an hour to water the flowers and (4/6) of an hour to weed her garden, so in total, she worked for (1/6) + (4/6) = 5/6 of an hour in her yard.

To add the two fractions, we need to have a common denominator, which is 6. Then we can add the numerators (1 + 4) to get 5.

⇒ 5/6

Thus, the final fraction is 5/6.

Can the sides of a triangle have lengths 6.2, 0.5, and 7.8?
yes or no

Answers

No, it's not possible for the sides of a triangle to have those lengths.

According to the triangle inequality theorem, the sum of any two sides of the triangle has to be bigger than the last side. Let's test this.

[tex]6.2+7.8\ \textgreater \ 0.5[/tex]

This inequality satisfies the triangle inequality theorem.

[tex]7.8+0.5\ \textgreater \ 6.2[/tex]

This also satisfies the theorem.

[tex]6.2+0.5 \textless \ 7.8[/tex]

Uh oh. This does not satisfy the triangle inequality theorem. Thus, it is not possible for a triangle to have these side lengths.
