Answer:

8.1

Step-by-step explanation:

Since we dealing with right triangles, we are going to use pythagoern theorem.

[tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex], where a and b are the two legs and c is the longest side or the slanted side( known as hypotunese.)

Let plug in the numbers

4^2+ b^2=9^2

16+b^2=81

b^2=65

sqr root of 65 is about 8.1

Answer:

A 40%

Step-by-step explanation:

The percentage of the people surveyed that are adults is; A: 40%

We are given;

Sample size of adults and children = 250

From the table, we see that;

Proportion of adults that can swim = 0.34

Proportion of adults that can't swim = 0.06

Thus;

Total proportion of Adults in the survey = 0.34 + 0.06

Total proportion of Adults in the survey = 0.40

Thus, percentage of people surveyed that are adults = 0.40 * 100% = 40%

Answer:

$4.00

Step-by-step explanation:

Find how much it would cost for one slice of bread by dividing 2.40 by 6 to get .4.

So .40 cents is for 1 slice of bread. If you got 10 slices of bread (multiply 10 by .4) you would get 4.

So it costs 4 dollars for 10 slices of bread.

Step-by-step explanation:

(2^-7 * 5^5)^2

From.the law of indices :

(a^m)^n = a^mn

Such that we multiply both powers

Hence the equation, W will become :

2^(-7*2) * 5^(5*2) = (2^-14 * 5^10)

Answer:

(-4,-1)

Step-by-step explanation:

-3x+10y=2

-3x+3y=9

-3x=2-10y

-3x=9-3y

2-10y=9-3y

2-9=10y-3y

7y=-7

y=-1

-3x+3(-1)=9

-3x-3=9

-3x=12

x=-4

Answer:

X=4, y=-1

Step-by-step explanation:

-3x+10y=2 multiple by 3

-3x+3y=9 multiply by 10

9x+30y=6

30x+30y=90

Subtract equation 1 from 2

30x-9x+30y-30y=90-6

21x+0=84

21x=84

Divide both side by 21

X=4

Substitute 4 for x in equation 1

3x+10y=2

3(4)+10y=2

12+10y=2

10y=2-12

10y=-10

Divide both side by 10

Y=-1

Answer:

63 inches

Step-by-step explanation:

the diameter is the entire line across the circle, the things needed to find out the circumference of the circle are the radius. that means you would divide your diameter in half to get 10. after you done that, you would input that into the equation:

c=2Π10

that would get you about 62.83 or 63

Answer:

The perimeter of the semi circle is gonna be π or 3.14

Step-by-step explanation:

So we know semi circle

The diameter is 2 so that basically also means the main circle diameter is also 2

we trying to find it’s circumference (perimeter)

We can follow the equation

C=πd

In this case d is 2

So 2π

And since that is full circle, half circle would be π
