Answer:

Step-by-step explanation:

Use the Pythagorean theorem:

$leg^2+leg^2=hypotenuse^2$

We have

$leg=3,\ leg=x,\ hypotenuse=\sqrt{10}$

Substitute:

$3^2+x^2=(\sqrt{10})^2$

$9+x^2=10$ <em>subtract 9 from both sides</em>

$9-9+x^2=10-9$

$x^2=1\to x=\sqrt1\\\\x=1$

The ratio of ages of kissi and esinam is 3:5 and esinam is 3:5 The sum of ages of all 3 is 147 years.whats the age difference be

Sergio039 [100]

Answer:

48 years.

Step-by-step explanation:

Consider the complete question is "The ratio of ages of kissi and esinam is 3:5 and that of esinam and lariba is 3:5. The sum of ages of all 3 is 147 years. whats the age difference between oldest and youngest ?"

It is given that

Kissi : Esinam = 3:5 = 9:15

Esinam : Lariba = 3:5 = 15:25

So, the combined ratio is Kissi : Esinam : Lariba = 9:15:25

Let ages of Kissi, Esinam, Lariba are 9x, 15x and 25x.

Sum of ages of all 3 is 147 years.

$9x+15x+25x=147$

$49x=147$

$x=3$

The value of x is 3. So, the age of all three are

$Kissi=9x=9(3)=27$

$Esinam=15x=15(3)=45$

$Lariba=25x=25(3)=75$

Since Lariba is oldest and Kissi is youngest, therefore, the difference between their ages is

$75-27=48$

Hence, difference between oldest and youngest is 48 years.

The coordinate will be (5, 12). Then the number of balloons that a group of 5 people pops will be 12.

<h3>What is coordinate geometry?</h3>

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

Rami works at a carnival dart game where groups of people try to pop balloons taped to a wall by throwing darts.

He records the number of people in each group and the total number of balloons they pop.

This graph represents Rami’s data.

Then the number of the balloons that a group of 5 people pops will be

The coordinate will be given as

Solve –3 + c = –8.<br> A. -5 B. 11 C. 5 D.-11

sergey [27]

Answer:

The answer is A. -5

Step-by-step explanation:

Write out the equation:

-3 + c = -8 Add 3 on both sides to isolate the varible on one side

c = -5 -8 plus 3 is -5

You must isolate the variable in order to solve equations with variables.

Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on <u><em>ONLY </em></u>one side of the equation.
