The bottom of a circular swimming pool with a diameter of
9 meters is painted blue. How many square meters are blue?

Answer:

x² + y² = 16

Step-by-step explanation:

(x-h)² + (y-k)² = r²   -- The standard form of equation of circle

(x-0)² + (y-0)² = 4²

Answer:

3 dollars and 9 cents.

Step-by-step explanation:

From the question given above, the following data were obtained:

Total amount = 20 dollars

Amount for gift A = 9 7/10 dollars

Amount for gift B = 6 2/5 dollars

Amount for gift C =?

The amount of money she has left for gift C can be obtained as follow:

A + B + C = 20

9 7/10 + 6 2/5 + C = 20

Change to improper fraction

97/10 + 32/5 + C = 20

(97 + 64)/10 + C = 20

161/10 + C = 20

Collect like terms

C = 20 – 161/10

C = (200 – 161)/10

C = 39/10

Change to mixed fraction

C = 3 9/10 dollars

C = 3.9

C = 3 dollars and 9 cents

Therefore, Kathy had 3 dollars and 9 cent for gift C

Answer:

m = -11/7

Step-by-step explanation:

change equation into slope-intercept form:

7y = -11x + 2

y = -[tex]\frac{11}{7}[/tex]x + 2/7

slope is the coefficient of the 'x' term

Answer:

17y+24

Step-by-step explanation:

simplify so the first step would be to multiply whats in the parentheses by the number outside in this case its 6 youd get:

12y+24+5y

then you simplify farther by adding like terms

17y+24

Answer:

The largest monthly house payment he can make is $1,218.

Step-by-step explanation:

In this question:

He spend at most 29% of his income on monthly house payments.

His monthly income is of $4,200.

What is the largest monthly house payment he can make?

0.29*4200 = 1218

The largest monthly house payment he can make is $1,218.

Answer: 0.034

Step-by-step explanation:3t-18=4(-3-43t)

3t-18=-12-172t

3t+172t=-12+18

175t/175=6/175

t=0.034

Answer:

y=-7/4x+5

Step-by-step explanation:

The line contains points at (4,-2) and (0,-5)

(y1-y2) / (x1-x2) = slope

(4,-2) =(x1,y1)

(0,-5) = (x2,y2)

(-2-5) / (4-0)

-7 / 4 = -7/4

y= -7/4x + b

plug in points for x and y to find b

-2=-7/4(4)+b

-2=-7+b

5=b

y=-7/4x+5

Answer:

D

Step-by-step explanation:

It cannot be Option A because the values are halve and there is nothing to distribute to them to make the values equal.

It's not option C because if you distribute 2y to each term in the parenthesis

you get -4[tex]y^{5}[/tex]  + 6y³  + 4y².   But where is the 8y² and -2y?

While Option B is equivalent, you can factor it out more and find the common factor of -2 to distribute among them as shown in option D

It is option D because distributing the -2y to each term solves to

-4[tex]y^{5}[/tex]  + 6y³   +  8y²  -2y.

Answer:

1 and 2

Step-by-step explanation:

Let the first number be x

Let the other number be y

x = 2y.....eqn 1

From eqn 1, the smaller number is y while the bigger number is x.

3x + 4y = 10.... eqn 2

Substitute x = 2y into eqn 2

3(2y) + 4y = 10

6y + 4y = 10

10y = 10

Divide both sides by 10

y = 10/10

y = 1

Substitute y= 1 into eqn 1

x = 2y

x = 2(1)

x = 2

Answer:

the pipe is 39.1 yards long.

Step-by-step explanation:

you would use pythagorean theorem (a²+b²=c²). plug the 25 in to the a² and plug the 30 in to the b² and figure out c² (it would look something like this 25²+30²=c²). to do that you need to square the 25² and the 30². the 25² would turn out to be 625 and the 30² would be 900 you would add them and get 1525. then you would squareroot 1525(

[tex] \sqrt{1525} [/tex]

) and get 39.05 and round it up and get 39.1 yards. dont forget to put the mesurements down

B. Independent-samples t test

Step-by-step explanation:

The test here is to find out if the participants of the sports program are becoming more active in general when compared to students who are not participating in the program.

Now, this will involve taking sample from the two independent groups to determine if there is statistical evidence that one is more active than the other.

Thus, the best test to use in this case will be the Independent-samples t test

Answer:

Perimeter = 30 cm

Step-by-step explanation:

10 cm x 3 = 30 cm

the required perimeter of the given rectangle is 30 cm.

Perimeter is the measure of the figure on its circumference.

The rectangle is 4 sided geometric shape whose opposites are equal in length and all angles are about 90°.

Here,
The length of a rectangle is 10 cm, which is 1/3 of it's perimeter.
Length = 1/3 of perimeter
10 = 1/3 perimeter
perimeter = 3 × 10
perimeter = 30 cm

Thus, the required perimeter of the given rectangle is 30 cm.

Answer:

[tex] \frac{1681}{4} [/tex]

or

[tex]105 \frac{1}{4} [/tex]

Step-by-step explanation:

[tex]10 \frac{ + 1}{ \times 4} [/tex]

10×4=40+1=41, that will be your numerator (number at the top of the fraction) and the denominator 4 will stay the same. (bottom number)

[tex] \frac{41}{4} [/tex]

the base and the height will remain the same.

Formula : base × height = Area

[tex] \frac{41}{4} \times \frac{41}{4} = \frac{1681}{16} [/tex]

16 goes into 1681 105 times remainder 1.

so as a mixed number it will be

Answer:

The equation is: [tex]800.5 + 45.25p \leq 1479.25[/tex]

The team can bring at most 15 players to the tournament.

Step-by-step explanation:

They rented a bus for $800.50 and budgeted $45.25 per player for meals.

This means that the cost for bringing p players is given by:

[tex]C(p) = 800.5 + 45.25p[/tex]

Members of a baseball team raised $1479.25 to go to a tournament.

This means that:

[tex]C(p) \leq 1479.25[/tex]

So

[tex]800.5 + 45.25p \leq 1479.25[/tex]

[tex]45.25p \leq 1479.25 - 800.5[/tex]

[tex]p \leq \frac{1479.25 - 800.5}{45.25}[/tex]

[tex]p \leq 15[/tex]

The team can bring at most 15 players to the tournament.
