if y varies directly as x, and y = 3 when x = 9, how will you find x when y = 36?

Answers

Answer 1

Answer:

(Some textbooks describe direct variation by saying " y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x . ") This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.

Answers

Answer:

7.4

Step-by-step explanation:

1. according to the condition (m+n+s+p+q)/5=12, it means (m+n+s+p+q)=60;

2. the required mean can be calculated:

[(m-4)+(n-3)+(s-6)+(p-2)+(q-8)]/5=[(m+n+s+p+q)-23]/5=[60-23]/5=37/5=7.4.

Marcelo has 6 red marbles in his marble collection. The red marbles make up 12% of all the marbles. How many marbles are in Marcelo’s collection? Show your work.

Answers

If 6/? makes of 12/100, we need to divid 100 by two to figure out the denominator of six. This is because to go from 12 to six (the numerators), you divide by two, so you do it for the denominator as well. This would give 6/50, which means there are 6 red marbles out of 50 marbles in the collection.

The total number of marbles in Marcel's collection is 50.

What is the percentage?

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Marcelo has 6 red marbles in his marble collection. Red marbles make up 12% of all the marbles.

The number of marbles in Marcel's collection is calculated as,

12% of marbles = 6

1% of marbles = 6 / 12

100% of the marbles= ( 6 / 12) x 100

100% of the marbles = 50

Lisa can harvest a field in 9.3 hours. Kali can harvest
the same field in 9.7 hours. Find how long it would take
them if they worked together.

Answers

Answer:

4.75 hours

Step-by-step explanation:

First you need to find the median of the two numbers. The fastest way to do it is to add 9.3 and 9.7 and divide by 2, which will give you 9.5. Since there's going to be two of them working, divide 9.5 by 2, and you get 4.75.

1/9.3 + 1/9.7 = 1/x

x=4.74789

If simplicity is to be applied,

rounded to tens: 0

rounded to ones: 5

rounded to tenths:4.7

rounded to hundreths:4.75

Answer:

Question 1: C. 4 × 3 × 2 ×  [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]

Question 2: The volume is [tex]\frac{1}{12}[/tex] or 0.083333333

Question 3: The volume fo the solid figure is 234

Step-by-step explanation:

1. Volume of a rectangular prism = (length × width × height) cubic units

Length = 4 ×  [tex]\frac{1}{8}[/tex]

Width = 3 × [tex]\frac{1}{8}[/tex]

Height = 2 × [tex]\frac{1}{8}[/tex]

Volume = 4 ×  [tex]\frac{1}{8}[/tex] × 3 × [tex]\frac{1}{8}[/tex]  × 2 × [tex]\frac{1}{8}[/tex]

Volume = 4 × 3 × 2 ×  [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]

So the correct option is:

C. 4 × 3 × 2 ×  [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]

2.

We have to fold the shape into a rectangular prism, look at the picture

Volume of a right rectangular prism =  (length × width × height)

Length = [tex]\frac{1}{3}[/tex]

Width =  [tex]\frac{1}{3}[/tex]

Height = [tex]\frac{3}{4}[/tex]

Volume = [tex]\frac{1}{3}[/tex] ×  [tex]\frac{1}{3}[/tex]  ×  [tex]\frac{3}{4}[/tex]

Multiply [tex]\frac{1}{3}[/tex] times [tex]\frac{1}{3}[/tex] by multiplying numerator times numerator and denominator times denominator.

[tex]\dfrac{ 1 \times 1 }{ 3 \times 3 } \times \left( \dfrac{ 3 }{ 4 } \right)[/tex]

Do the multiplications in the fraction [tex]\dfrac{ 1 \times 1 }{ 3 \times 3 }[/tex]

[tex]\dfrac{ 1 }{ 9 } \times \left( \dfrac{ 3 }{ 4 } \right)[/tex]

Multiply [tex]\frac{1}{9}[/tex] times [tex]\frac{3}{4}[/tex] by multiplying numerator times numerator and denominator times denominator.

[tex]\dfrac{ 1 \times 3 }{ 9 \times 4 }[/tex]

Do the multiplications in the fraction [tex]\dfrac{ 1 \times 3 }{ 9 \times 4 }[/tex]

[tex]\frac{3}{36}[/tex]

Reduce the fraction [tex]\frac{3}{36}[/tex] to the lowest terms by extracting and canceling out 3

Fraction form: [tex]\frac{1}{12}[/tex]

or

Decimal form: 0.083333333

So the volume of the right rectangular prism is [tex]\frac{1}{12}[/tex]

3. Look at the picture with the solid figure labeled

We can think of this shape as two different prisms ( A and B)

Volume of A = 4.5 × 6 × 6.5 = 175.5

Volume of B = 3 × 3 × 6.5 = 58.5

Total volume of the whole figure = 175.5 + 58.5

175.5 + 58.5 = 234

So the volume of the solid figure is 234

A town has a population of 2000 and grows at 4. 5% every year. What will be the population after 13 years, to the nearest whole number?.

Answers

Answer:

3544 people

Step-by-step explanation:

We can start by representing this as an exponential function, in the form [tex]y=a(b)^x[/tex]

2000 will be our a, or our initial value. We must convert our multiplier, 4.5% to a decimal, which is 1.045. 13 is our input since it's our number of years where we want to find the population. Now that we have our variables, lets make an equation.

[tex]y=2000(1.045)^13[/tex]

PEMDAS states that we first do exponents, so lets raise 1.045 to the 13th power.

[tex]y=2000(1.77219609724)[/tex]

Now we multiply by 2000!

[tex]y= 3544.39219448[/tex]

Rounded to the nearest whole number is 3544. Therefore, there will be 3,544 people living in the town in 13 years.

Area = ((-1)*(-6 - -6) + (-6)*(-6 - 2) + (3)*(2 - -6)) / 2

Solve the following equations:


a. 3x + 5y = 8 ,

4x – 3y = 1


b. 6p + 4q = 20,

5p – 2q = 6

Answers

Step-by-step explanation:

a) 3x + 5y = 8

4x - 3y = 1

• using the elimination method:

3x + 5y = 8 (×4)

4x -3y = 1 (×3)

12x + 20y = 32

12x -9y = 3

subract 12x from both equation:

20y - - 9y= 32 -3

20y +9y = 29

29y= 29

y= 29/29

y= 1

- substituting y= 1 in :

4x - 3y= 1

4x - 3(1) = 1

4x -3 = 1

4x = 1 + 3

x = 4/4

x= 1

b) 6p+ 4q = 20

5p - 2q = 6

• using the elimination method:

6p + 4q = 20

5p - 2q = 6 (×2)

6p + 4q = 20

10p - 4q = 12

add 4q + -4q to eliminate q.

6p+ 10p = 20+12

16p = 32

p = 32/ 16

p = 2

- subtituting p = 2 in :

5p - 2q = 6

5(2) -2q =6

10 -2q = 6

-2q = 6 - 10

q = -4 / -2
