SOMEONE FILL IN THE BLANK PLEASE!! The diameter of a sphere is 16 cm. The volume of the sphere is _____

The equation of proportional situation is y = ax.

Therefore your answer is y = -2x + 14

Answer:

 x=0 and y=2

Step-by-step explanation:

We have been given system of equations:

2x+5y=10     (1)

And 2x+3y=6     (2)

Subtract equation (2) from(1) we get:

2y=4

y=2

Now, substitute y=2 in equation(2) we get:

2x+3(2)=6

2x+6=6

2x=0

x=0

Hence, x=0 and y=2

Answer:

2 miles

Step-by-step explanation:

We can use ratios to solve this problem

3/4 miles         x miles

--------------- = ---------------

3/8 hours          1 hours

Using cross products

3/4 * 1 = 3/8 * x

Multiply by 8/3 to isolate x

3/4 * 8/3 = 3/8*8/3 *x

8/4 = x

2 =x

Answer:

Step-by-step explanation: I would say 3 because when you divide 54 by 9 you get 6. Then when you divide 6 by 2, you get 3. Hope this helps‼ ☺

The number of students gym teacher has putted in each team is, 3

A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.

Given that,

A third-grade gym class has 54 students

The gym teacher divides them into 9 groups

Then divides each group into 2 teams

The number of students in each team = ?

Number of students in a group =   54/9

                                                    =    6 students

Then each group divided into two teams,

Number of students in each team = 6/2

                                                         = 3

Hence, the number of students is 3

Answer:

x=9/4

Step-by-step explanation:

Performing the indicated multiplication, we get

2x - 3x + 4 = 3x - 5

Combining the x terms, we get -4x = -9, so that x = 9/4.

Answer:

No, it only equals 1 3/4.

Step-by-step explanation:

You first need to break up 1/2. You should know it equals 2/4, so adding 1 1/4 and 2/4, it will equal 1 3/4

Answer:

If a car with a blowing horn is moving toward you, the pitch sounds higher than the actual emitted frequency.

Step-by-step explanation:

In figure,

        V= speed of wave

         U= speed of car

When car moving towards you, then

Car travels a distance in time T = VT

 Wave travels a distance in time T = UT

From figure,

                    change in wavelength (λ') = VT - UT= T(V-U)

Now,

        V = λ' f'         (f' →frequency observed by you)

         f' = V ÷ λ' = [tex]\frac{V}{T(V-U)}[/tex]

We know that

                      [tex]\frac{1}{T}[/tex] = f

Then,

        f' =  [tex]\frac{Vf}{V-U}[/tex]

        f' = [tex]\frac{f}{1-\frac{U}{V} }[/tex]

Hence, we can say that

           frequency increases as source moves toward you.

Answer:

B. Increase

Answer:

A Yana's average number of points is 0.5 points greater than Amber's

Step-by-step explanation:

i added up all of Yana's points = 15

I added up all of Amber's points = 12

then i divided them both by 6 because there is 6 numbers total so then i got

Yana = 2.5 Amber = 2

2.5 - 2 = 0.5 so Yana's average number of points is 0.5 points greater than Amber's

Answer:

Answer (a):

s + l = 22 ... (i)

43s + 75l = 1234 ... (ii)

Answer (b)

9 large dogs.

Step-by-step explanation:

Paws at Play made a total of $1234 grooming 22 dogs.

Paws at Play charges $43 to groom each small dog and;

$75 for each large dog.

Let the number of small dogs be 's'

And the number of large dogs be 'l'

A system of equations will be:

s + l = 22 ... (i)

43s + 75l = 1234 ... (ii)

Solving this set of simultaneous equations by elimination, we simply multiply (i) by 43 to get;

43s + 43l = 946 ... (i)

43s + 75l = 1234 ... (ii)

Subtracting (i) from (ii) we get;

32l = 288 , l = [tex]\frac{288}{32}[/tex] = 9

So there are 9 large dogs.

[tex]\( m\% \) of \( n \) is \( \frac{{m \times n}}{{p}}\% \) of \( p \).[/tex]

To find what percentage m% of n is of p, you would calculate:

[tex]\[ \text{Percentage} = \frac{{\frac{m}{100} \times n}}{p} \times 100\% \][/tex]

Simplify the expression:

[tex]\[ \text{Percentage} = \frac{{m \times n}}{{100 \times p}} \times 100\% \][/tex]

[tex]\[ \text{Percentage} = \frac{{m \times n}}{{p}}\% \][/tex]

Answer:

38809/(4pi) cm^2

Step-by-step explanation:

So the circumference of the wheel is 197. So to find the radius, we divide by 2 pi. So now we have 197/(2pi) as the radius. Now we have to find the area, so it is 38809/(4pi)

The area of the solid wheel is  3090 cm².

The circumference of a circle is the distance around the circle which is 2πr.

The diameter of a circle is the largest chord that passes through the center of a circle it is 2r.

We know circumference is the distance around the circle which is 2πr.

Given, Each time a solid bicycle wheel turns, the bicycle travels 197cm.

Therefore,

2πr = 197.

r = 197/π×2.

r = 31.37 cm.

Therefore, The area of the solid wheel is,

πr².

= 3.14×(31.37)² cm².

= 3090 cm².

Answer:

f(x) + g(x) = 6x^2 + 28x + 36

Step-by-step explanation:

Thirty eight

You begin to solve this by writing it like this [just as you have it].

f(x) = x^2 + 5                    Now put g(x) where you see x

f(g(x)) = [g(x)]^2 + 5          Now substitute the right side of g(x) wherever you see g(x)

f(x - 4) = [x - 4]^2 + 5        Expand the brackets

f(x- 4) = x^2 - 8x + 16 + 5

f(x - 4) = x^2 - 8x + 21

=======================

Thirty Nine

f(x) = (x + 4)^2

g(x) = 5(x + 2)^2

Expand f(x)

f(x) = x^2 + 8x + 16

Expand g(x)

f(x) + g(x) = x^2 + 8x + 16 + 5x^2 + 20x + 20

f(x) + g(x) = 6x^2 + 28x + 36

Answer: Yoghes has $0.87

Step-by-step explanation: We want to know the total amount of money that Yogesh has:

each quarter values 25¢, a dime values 10¢, and a penny values 1¢

(or the values can be written as $0.25, $0.10 and $0.01 respectively)

Yogesh has 3 quarters, so this means he has: 3*$0.25 = $0.75

he has 1 dime, so in dimes, he has: $0.10

he has 2 pennies, so in pennies, he has: 2*$0.01 = $0.02

If we sum up the 3 amounts, we have:

Total = $0.75 + $0.10 + $0.02 = $0.87

1. -4 and 3/10 and 4.51010910921... are all rational numbers.

2. Yes 81 is a perfect square because its square root is 9 which is a real number.

3. 5

4. Well the closest perfect square to 52 is 49 and 64. 52 is closer to 49 and the square root of 49 is 7 so the estimated value of the square root of 52 is about 7.

False- every square root is not rational because some aren't perfect squares, meaning the result is a decimal that keeps going forever.

Answer:

A.

Step-by-step explanation:

delta = [tex]b^{2} - 4ac = (-8)^{2}-4*1*12 = 64 - 48 = 16[/tex]

[tex]x_{1} = \frac{b-\sqrt{delta}}{2a} = \frac{8+4}{2} = 6[/tex]  

[tex]x_{2} = \frac{b+\sqrt{delta}}{2a} = \frac{8-4}{2} = 2[/tex]

By calculating 2/3 of 600, we find that 400 seeds sprouted, which means 200 seeds did not sprout.

To determine how many seeds did not sprout, we start by calculating the number of seeds that did sprout. Given that 2/3 of the 600 seeds sprouted, we multiply 600 by 2/3:

600 × (2/3) = 400

So, 400 seeds sprouted. Next, we subtract this number from the total number of seeds to find out how many did not sprout:

600 - 400 = 200 seeds

Therefore, 200 seeds did not sprout.
