A city council organized a marathon race to promote good health. There were 3 times as many female participants as male participants in the marathon. If the total number of participants was 812, how many participants were male

Answers

Answer:

609 males

Step-by-step explanation:

A city council organized a marathon race to promote good health.

Let the number of

Females = x

Males = y

There were 3 times as many female participants as male participants in the marathon.

3x = y

If the total number of participants was 812,

x + y = 812..... Equation 1

We substitute 3x for y in Equation 1

x + 3x = 812

4x = 812

x= 812/4

x = 203 females

3x = y

Solving for y

3(203) = 609 males

The number of males participants = 609

The sum of three numbers is 107 . The first number is 8 less than the third . The second number is 3 times the third . What are the numbers ?

Answers

First number = x
Third number = x - 7
Second number = 2(x - 7)
x + 2(x - 7) + x - 7 = 107
x + 2x - 14 + x - 7 = 107
Collect like terms.
4x - 21 = 107
4x = 128
x = 32
First number = 32
Second number = 50
Third number = 25
Total = 107.

Answer:

(x - 8) + 3x + x = 107

x - 8 + 3x + x = 107

5x - 8 = 107

5x = 115

x = 23, SO...

The first number is 23-8, which is 15

The second number is 3 x 23, which is 69

The third number is 23

15 + 69 + 23 = 107 CHECK!

A rectangular garden is to cover 416 square feet of area. If the width is 10

feet less than the length, find the dimensions of the garden.

Answers

Answer:

Length = 26 feet, Width = 16 feet

Step-by-step explanation:

Let the length be l.

Width b = l-10

The area of a rectangular garden, A = 416 feet²

We need to find the dimensions of the garden. The area of a rectangular shaped object is given by :

[tex]A=lb\\\\l(l-10)=416\\\\l^2-10l-416=0\\\\l=26\ ft,-16\ ft[/tex]

Neglecting the negative value, the length of the garden is 26 feet and the width is 12-10 = 16 feet.

h(x) = 7 - x - 2x^5

h(-1) = 7 + 1 - 2(-1)^5

h(-1) = 7 + 1 + 2

h(-1) = 10

Now differentiate h(x)

h'(x) = -1 - 2*5*x^4

h'(x) = -1 - 10x^4

h'(x) = -1 - 10(x)^4

h'(x) = -1 - 10 (x)^4

h'(-1) = -1 - 10(10000)

h'(-1) = -1 - 100000

h'(-1) = - 99999

Answer:

-8.4 + 6 hope this helped!

Step-by-step explanation:

Answer:

-38

Step-by-step explanation:

-8.x – 3y

x = 4

y = -2

Since we have the value for x and y we can use that and substitute it into the expression

-8(4) - 3 (-2)

-32 - 6

When you add 2 negative numbers (or subtract them) they will give you a bigger number so think of it as adding 2 positive numeber, but then putting a negative sign in the beginning of it.

-32 - 6

-38

Elijah played 98 consecutive games of soccer without being taken off the field. Then, after a single game on the sidelines, he played another string of consecutive games, although this string was 50% shorter. How many consecutive games was that?

Answers

Answer:

If the game will start at 11:00 A.M., but the players must arrive at the field three-quarters of an hour early to warm up, it refers to 8:45 a.m. Why? If we start to count in 11 backward and start to trace the three-quarters, it shows that 10:45, 9:45, and 8:45 are the three-quarters. So Hamid statement that he has to be at the field at 9:45 A.M is not correct.

Answer:

So the first step would be is to multiply the denominators so you would get this:

6/30 + 5/30

Then you would have 11/30 no simplification needed.

Se image below for more info:

Answer:

11/30

Step-by-step explanation:

To add fractions, you need to find the common denominators

the common denominator for 5 and 6 is 30, because 5*6 = 30

1/5 times (6/6) to get a common denominator of 30. Remember, you have to multiply the numerator by 6 too!

1           6          6

_    x    _    =    _

5         6          30

Now, we just have to multiply 1/6 by (5/5) to get a common denominator of thirty.

1           5          5

_    x    _    =    _

6         5          30

5             6         11

_     +      _    =    _

30          30        30

You final answer should be 11/30
