Answer 1
Lets split this up

30x^3 -5x^2  turns into 5x^2(6x-1)

-18x+3 turns into -3(6x-1)

we can then combine them to get (5x^2-3) (6x-1)

In the equation y = 2x -3 if x = 3, what is the ordered pair of the solution?

Answers

-4.31 x 3.09 + (-0.98)

Answers

To find the answer, we just simply use PEMDAS, which means:
Parentheses
Exponents
Multiplication
   (and/or)
Division
Addition
   (and/or)
Subtraction

Solve the problem in this order. Since no operations are in the parentheses, we can skip that. The first operation we will do is multiplication. I can't really explain multiplication here, but you hopefully already know it, so multiply -4.31 by 3.09. Although there are negatives and decimals, treat it as a normal multiplication problem while doing the math.

This will give you -13.3179, just move the decimal point down, and since a positive is being multiplied by a negative, the answer is negative. Once you have this number, just add it to -0.98. This is the same as subtracting, since it is negative, so in other words, just subtract 0.98 from -13.3179, and you have your answer.

This would be -14.2979, or roughly -14.2.

A culture started with 3000 bacteria. After 4 hours, it grew to 3,600 bacteria. Predict how many bacteria will be present after 10 hours. Round your answer to the nearest whole number. Use exponential growth formula

Answers

Hello Shannonrodrigue. You can solve this by setting up an exponential growth equation.

[tex]A = A_ob^t[/tex]
[tex]3600 = 3000b^4[/tex]

Now we solve for b
[tex]3600 = 3000b^4[/tex]
[tex]\frac{3600}{3000} = \frac{3000b^{4}}{3000}[/tex]
[tex]\frac{6}{5} = b^4[/tex]
[tex]\sqrt[4]{\frac{6}{5}} = \sqrt[4]{b^4}[/tex]
[tex]\sqrt[4]{\frac{6}{5}} = b[/tex]

Now that we have found b, we can use the equation [tex]A = 3000b^t[/tex] to predict how many bacteria will be present after 10 hours.
[tex]b = \sqrt[4]{\frac{6}{5}}[/tex]
t = 10
[tex]A = 3000b^t[/tex]
[tex]A = 3000\sqrt[4]{\frac{6}{5}}^{10} = 4732.3228 = 4732 [/tex]

Answer = 4732



the product of three consecutive nonzero integers

Answers

Final answer:

To find the product of three consecutive nonzero integers, multiply the first number by the next two numbers in the sequence.

Explanation:

If the first integer is n, the next will be n+1 and the next to it will be n+2

The product of three consecutive nonzero integers can be calculated using the formula:

n * (n+1) * (n+2)= n(n^2 + 3n+ 2)=n^3 +3n^2 + 2n

where 'n' represents the first integer. For example, if we take 'n' as 2, the three consecutive nonzero integers would be 2, 3, and 4. So, the product would be 2 * 3 * 4 = 24= (2)^3+  3*(2)^2+ 2*2

Your baseball team has a goal to collect at least 160 blankets for a shelter. Team members brought 42 blankets on monday and 65 on wednesday . Write and solve an inequality to find out how many blankets the team has to collect on friday?

Answers

y=160-(65+42). so it's 53

Answer:

Atleast 53

Step-by-step explanation:

We are given that your basketball team has a goal  to collect atleast 160 blanket for a shelter.

Team member bought blankets on Monday =42

Team member bought blankets on Wednesday=65

We have to write an inequality and find the number of blankets  has to collect on Friday.

Let x be the number of blankets  bought by team members on Friday

According to question

[tex]42+65+x \geq 160[/tex]

[tex]107+x \geq 160[/tex]

Subtract 107 on both sides

[tex]107-107+x\geq 160-107[/tex]

[tex]x\geq 53[/tex]

Hence, team members bought atleast 53 blankets on Friday .

The united states has 12,383 miles of coastline. If 0.8% of the coastline is located in Georgia, about how many miles of coastline are in Georgia

Answers

Total miles: 12, 383 (given)
0.8% * 12383
99.064 miles

Answer:

99.064  miles of coastline are in Georgia.

Step-by-step explanation:

Consider the provided information.

The united states has 12,383 miles of coastline and 0.8% of the coastline is located in Georgia.

Now we need to find about how many miles of coastline are in Georgia.

Thus solve this as shown:

0.8% of 12,383

[tex]\frac{0.8}{100} \times 12,383[/tex]

[tex]0.008 \times 12,383[/tex]

[tex]99.064[/tex]

Hence, 99.064  miles of coastline are in Georgia.

what is 50/12 in a mixed number

Answers

just divide 50 by 12

4 1/6
A fraction is when there is less than 1 whole i.e. 1/2
A mixed fraction is when there is more than 1 whole i.e. 1 3/4
A improper fraction is when there is more than 1 whole i.e. 50/12

As you may have observed, the thing which differentiates a mixed fraction from an improper fraction is that a mixed fraction's numerator is never bigger than it's denominator.
:)
50/12 is an improper fraction,
To convert this into a mixed fraction, we can find out how many times 50 fits in 12: 50/12 = 4.16666
So we know there are 4 wholes, which as twelfths are 48/12;
We can then observe the difference between 50 and 48 is 2 twelfths

So 50/12 as a mixed number/fraction is 4 wholes and 2 twelfths 
which can also be written as 4 2/12 and then simplified to 4 1/6

Two of the angles in a parallelogram measure 5x° and 7x°. what is the value of x?

Answers

In a parallelogram, Consecutive angles are supplementary 5x+7x=180,so x= 15

The value of x is 15.

What is parallelogram?"It is a quadrilateral with opposite sides parallel.""The opposite angles of parallelogram are equal. "

For given question,

Two of the angles in a parallelogram measure 5x° and 7x°

The measure of an angle opposite to 5x° is also 5x°

Similarly the measure of an angle opposite to 7x° is also 7x°

So, we have the four angles of parallelogram as 5x°, 7x°, 5x°, 7x°

We know, the sum of all angles of quadrilateral is 360°

⇒ 5x° + 7x° + 5x° + 7x° = 360°

⇒ (5 + 7 + 5 + 7) x = 360

⇒ 24x = 360

⇒ x = 15

Therefore, the value of x is 15.

5x-4(2x+11)=13

solve for x
show all work please

Answers

First you have to distribute the 2x+11.
So multiply -4x2x and -4x11. 
5x-8x-44=13
Add all your like terms so 5x+-8x.
-3x-44=13. Now add 44 to both sides.
-3x= 57. Now divide both sides by -3 to get the x by itself. 
x=-19


5x-4(2x+11)=13

1)distribute the -4 to the numbers within the parenthesis.

5x-8x-44=13

2) next step you combine light terms.
''5x-8x=-3x''
so now you have -3x-44=13
3) add 44 on both sides
and you're left with -3x=57
4) divide both sides by -3 in order to solve for x; x divided by any number is always x, and 57divided by -3 is -19
5) so you're left with [n=-19] as your final answer

Gina's number is 2 more than sara's. the sum of their numbers is 68. what are their numbers?

Answers

Answer:

Gina=35, Sara=33

Step-by-step explanation:

Gina's number is 2 more than Sara's.

Lets start by saying cookies as the number.

Sum = 2 numbers add together. The answer to the equation. Lik 5+5=10. 10 is the sum.

You only know that Gina has 2 more cookies than Sara.

If Sara has 3 cookies then Gina has 5 cookies. Whats the Sum? 8.

So, you figure out an random big number but, smaller than 68.

Lets do 68 to try now.  So you do 68/2 = 34. You remember that Gina has 2 more than Sara. So, 35 cookies for Gina. So, you can guess that Sara has 33 cookies.
