You are making balloon arrangements for a birthday party. there are 16 white balloons and 24 red balloons. each arrangement must be identical. what is the greatest number of arrangements you can make using every balloon?

Answers

This is basically a GCF problem. To find the GCF, we list the factors of each number.
24 = 1×24, 2×12, 4×6, 8×3 ...

16 = 1×16, 2×8, 4×4, ... 

The greatest common factor is 8 because it is the greatest factor we can find.

One variable linear equation is an equation that has a variable and the exponent number is one. Can be stated in the form:

[tex]\large{\boxed{\bold{ax=b}}}[/tex]

or

ax + b = c, where a, b, and c are constants, x is a variable

Whereas the two-variable linear equation is a linear equation that has 2 variables and the exponent is one

Can be stated in the form:

 [tex]\large{\boxed{\bold{ax+by=c}}}[/tex]

ax + by = c

x, y = variable

There are 2 general steps to solving a linear equation of one variable:

1. add or subtract both segments with the same number so that it is expected that in one segment there are only variable modifiers or constant numbers 2. Change the equation into a simple form so that the coefficient of the variable is 1

This can be done by dividing or multiplying by equal numbers

An equation will remain equivalent if both segments are multiplied or divided by the same number

In the equation

2x + 5 = 19

The right steps to complete it according to the images included are:

1. 2x + 5 = 9 ⇒ given 2. both segments are subtracted by the number 5

 2x + 5 -5 = 9-5  ⇒subtraction property of equality

3. 2x = 14  ⇒subtract 4. both segments are divided by 2 so that the coefficient x = 1

Answers

x        -4
x         1 

(x-4) (x + 1)

your answer is C.x - 4

hope this helps

Answer:

c) x - 4

Step-by-step explanation:

To do a factorization of this kind of trinomial there is a technique very easy to do it.

First, you need to see the numbers that are along with the x and the independent number.

In this case -3 and -4 (I will call them b and c)

Next, you need to think in two numbers that can acomplish the following:

x * y = c

x + y = b

So, first, think, which are two numbers that you can multiply between them to give as a result -4?.

In this case it would be -4 and 1 (-4*1 = -4)

These numbers if you do a sum you'll get -3:

-4 + 1 = -3

So the factorization becomes this:

(x - 4) (x - 1)

So, one of the factors is x - 4. Option c

Harry buys a sofa set that costs $2000.00. He pays for it by installments at an interest rate of 5% per year. What is the total amount he has to pay at the end of the one year?

Answers

2000 = 100%   
    ?    =  105%

To calculate~~~~


[tex] \frac{2000}{100} [/tex]   X 105 

= $2100.00

Harry is required to pay an additional $100 as interest for one year on the $2000 sofa, bringing the total payment to $2100 at the end of the year.

Harry buys a sofa set at a cost of $2000 with an installment plan that includes an interest rate of 5% per annum. To calculate the total amount Harry needs to pay at the end of one year, you need to calculate the interest and then add it to the principal amount.

The interest for one year is calculated as follows:

Interest = Principal imes Rate imes Time.

Interest = $2000 imes 5% imes 1 year.

Interest = $2000 imes 0.05  imes 1.

Interest = $100.

Now, we add the interest to the principal amount to find the total amount Harry has to pay by the end of the year:

Total Amount = Principal + Interest.

Total Amount = $2000 + $100.

Total Amount = $2100.

Therefore, Harry will have to pay a total of $2100 at the end of one year.

What is the equation of the line that is parallel to the given line and passes through the point (−4,−6 )?

A. x = −6
B. x = −4
C. y = −6
D. y = −4

Answers

The question says that the line is parallel to the line above, so it is horizontal.  When the line is horizontal it will be a 'Y='  Then, you take a look at the y axis and check to see what part of the axis the line is going through.  Therefore, you can figure out that the awnser is C.  I hope this explanation helps!

we know that

The given line is parallel to the x-axis

so

the equation of the line that is parallel to the given line and passes through the point [tex](-4,-6 )[/tex] will be equal to the y-coordinate of the point

The y-coordinate of the point is [tex]-6[/tex]

therefore

the equation is

I believe it is 64 degrees

In this problem, we want to find the measure of the third angle of the given triangle. Remember that the sum of the interior angles of a triangle is equal to 180 degrees.

Let's start off by writing an equation representing the sum of the interior angles of the given triangle.
y+79+37=180

Now, let's solve the equation for the variable 'y'.
y+79+37=180

Combine like terms:
y+116=180

Subtract 116 from both sides of the equation:
y+116-116=180-116
y=64

The measure of angle y is 64 degrees.

Is the following definition of perpendicular reversible? If yes, write it as a true biconditional. Two lines that intersect at right angles are perpendicular.

A. The statement is not reversible.

B. Yes; if two lines intersect at right angles, then they are perpendicular.

C. Yes; if two lines are perpendicular, then they intersect at right angles.

D. Yes; two lines intersect at right angles if (and only if) they are perpendicular.

Answers

A biconditional statement is a statement in which it is inherently true but when the clauses are exchanged, the statement would still be regarded as true. In this case, the statement is biconditional. The answer that would make sense here would be C. Yes; if two lines are perpendicular, then they intersect at right angles.

Mick has a bag with 2 mint sticks, 11 jelly treats, and 7 fruit tart chews. If he eats one piece every 10 minutes, what is the probability his first two pieces will be a jelly treat and a mint stick?

Give your answer in a percent.

Answers

Final answer:

To find the probability, calculate the probabilities of selecting a jelly treat and a mint stick. Then multiply these probabilities together to find the overall probability.

Explanation:

To find the probability that Mick's first two pieces will be a jelly treat and a mint stick, we need to calculate the probability of selecting a jelly treat and a mint stick from the bag.

First, we need to find the total number of pieces in the bag: 2 mint sticks + 11 jelly treats + 7 fruit tart chews = 20 pieces.

The probability of selecting a jelly treat as the first piece is: 11 jelly treats / 20 total pieces = 0.55 or 55%.

After Mick has eaten one piece, there are now 19 pieces left in the bag.

The probability of selecting a mint stick as the second piece is: 2 mint sticks / 19 remaining pieces = 0.105 or 10.5%.

Therefore, the probability that Mick's first two pieces will be a jelly treat and a mint stick is 55% * 10.5% = 0.055 or 5.5%.

There are between 50 and 60 eggs in a basket. When Mohammed counts by 3's, there are 2 eggs left over. When he counts by 5's there are 4 left over. How many eggs are there in the basket?

Answers

Hello There!

3 : 48, 51, 54, 57, 60
5: 50, 55, 60

Choose a number that satisfies both:

59

When divided by 3 it has a remainder of 2
When divided by 5 it has a remainder of 4.

There are 59 eggs in the basket.

Hope This Helps You!
Good Luck :)

The correct answer is:

59

Explanation:

The numbers between 50 and 60 that are divisible by 3 are

51, 54, 57, 60

The numbers between 50 and 60 that are divisible by 5 are

50, 55, 60

We know that when he counts by 3s, he has 2 left over; this means the number he counts to is 2 fewer than the number of eggs.  This means, counting by 3s, we could have

51+2, 54+2, 57+2, or 60+2 = 53, 56, 59, 62

62 is not an option, since we know we have between 50 and 60 eggs; this gives us 53, 56 or 59.

We also know that when he counts by 5s, he has 4 left over; this means the number he counts to is 4 fewer than the number of eggs.  This means, counting by 5s, we could have

50+4, 55+4, 60+4, or 54, 59, 64

64 is not an option, since we know we have between 50 and 60 eggs; this gives us 54 or 59.

The only number in both lists is 59, so this must be the answer.

The answer to this question would be: 1 g/cm 3
The density of water should be 1g/cm3. If you want to know how much it is in a milliliter, then you need to convert the cm3 into the milliliters. But the question is about density. The density of water will not be changed if its volume became less. The volume only used to determine the water weight.
