What is 4 less than three sevenths of y

Answers

Answer:

[tex]\frac{3}{7}y - 4[/tex]

Step-by-step explanation:

Let's start with the part "three sevenths of y". In this statement, "of" means multiply or times. So, let's apply that. It would now be three sevenths times y. Three sevenths times y looks like this: 3/7y"4 less than" means subtraction because less than means subtractions. So our first part is 3/7y. Now let's add less 4 less than: 3/7y - 4.

If r=8 units and h=11 units, what is the volume of the cylinder shown above? Use 3.14 for pi. HELP ME

Answers

Answer:

The answer is

2210.56 units³

Step-by-step explanation:

Volume of a cylinder is given by

V = πr²h

where

r is the radius of the cylinder

h is the height

From the question

r = 8 units

h = 11 units

Substitute the values into the above formula and solve

V = 3.14(8)²(11)

= 3.14(64)(11)

= 3.14 × 704

We have the final answer as

V = 2210.56 units³

Name the independent and dependent variable.

Answers

Answer: Group 1 is the dependent variable, and group 2 is the independent

Step-by-step explanation: The dependent variable is the variable that is being measured or tested in an experiment. So, Group 1 would be the dependent variable, because as it says the the group 1 plants were spoken to and hand watered as in they changed the outcome of the experiment.

The independent variable is the variable the experimenter changes or controls. So, the independent variable would be group 2 because the group 2 plants outcome was not determines anything but it's self.

Peter purchases a baseball card for $150 as an investment. His research tells him that the value of
the card should double every 3 years. When will the card reach a value of $ 4000?

Answers

Answer:

6 years

Step-by-step explanation:

Given

[tex]Initial\ Investment = 150[/tex]

[tex]Ratio = double[/tex]

Required

When will it get to 4000

This question illustrates a geometric progression and will be solved using:

[tex]T_n = ar^{n-1}[/tex]

In this case;

[tex]T_n = 4000[/tex]

[tex]r = double = 2[/tex]

[tex]a = 150[/tex]

So, we're to solve for n

[tex]4000 = 150 * 2^{n - 1}[/tex]

Divide through by 150

[tex]\frac{4000}{150} = 2^{n-1}[/tex]

[tex]26.67= 2^{n-1}[/tex]

Take Log of both sides

[tex]Log26.67= Log2^{n-1}[/tex]

Apply law of logarithm

[tex]Log26.67= ({n-1})Log2[/tex]

Take Log values

[tex]1.42602301569 = (n - 1) * 0.30102999566[/tex]

Make n - 1 the subject

[tex]n - 1 = \frac{1.42602301569}{0.30102999566}[/tex]

[tex]n - 1 = 4.73714591984[/tex]

Add 2 to both sides

[tex]n = 1 + 4.73714591984[/tex]

[tex]n = 5.73714591984[/tex]

[tex]n = 6[/tex] (Approximated)

What is 4,672.183 rounded to the nearest hundredth?​

Answers

4672.18 is the answer

Answer:

The correct answer is 4,672.18.

Step-by-step explanation:

To solve this problem, we must look at the number we are given and determine what numbers are in which places.  The 4 is in the thousands place, the 6 is in the hundreds place, the 7 is in the tens place, the 2 is in the ones place, the 1 is in the tenths place, the 8 is in the hundredths place, and the 3 is in the thousandths place.  

The question asks us to round to the nearest hundredth, so this means that the number in the hundredths place should be the final digit.  In the number given, the number 8 is in the hundredths place.  Since the following digit (3) is less than 5, we round down and keep the 8 in the hundredths place.  This makes our answer 4,672.18.

Answers

Answer:

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ]

here (x₁, y₁ ) = G(- 2, 46) and (x₂, y₂ ) = L(4, 10), thus

midpoint = ([tex]\frac{-2+4}{2}[/tex] , [tex]\frac{46+10}{2}[/tex] ) = ([tex]\frac{2}{2}[/tex] , [tex]\frac{56}2}[/tex] ) = (1, 28 )

January, Scott earned $8,999. In February, he earned $2,387 more than in January. In March, Scott earned the same amount as in February. How much did Scott earn altogether during those three months?

Answers

Answer:I believe it's 31,771

Step-by-step explanation: you first need to add 8,999 + 2,387 to get 11,386 then add 11,386 + 11,386 to get 22,772 and then add 8,999 to get 31,771.

Scott earns $31,771 altogether during those three months.

What are Arithmetic operations?

Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

We have to determine that Scott earn altogether during those three months.

We have been given that in January, Scott earned $8,999.

In February, he earned $2,387 more than in January.

So we have to add the amount of January and 2,387, we get

⇒ 8,999 + 2,387 = 11,386

In March, Scott earned the same amount as in February.

So the amount of March = 11,386

Therefore, He earns altogether during those three months as

⇒ 8,999 + 11,386 + 11,386

Apply the Addition operation in the above expression,

⇒ 31,771

Hence, Scott earns $31,771 altogether during those three months.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

Two sides of right triangle are,

⇒ 5 cm, 12 cm

Since, The triangle is a right triangle.

So, We can apply the Pythagoras theorem as;

Let the measure of missing side = x

⇒ x² = 5² + 12²

⇒ x² = 25 + 144

⇒ x² = 169
