2 1/7:15a=5/14:0.8. solve

Answer:

x = 12

Step-by-step explanation:

if l and m are parallel that means that since the two angles are consecutive interior they add to 180

so add them both and set that to 180

9x - 4 + 5x + 16 = 180

now combine like terms

14x + 12 = 180

subtract 12 from both sides

14x = 168

divide everything by 14

x = 12

that is the answer

Answer:

Step-by-step explanation:

Let's find x:-

[tex]\sf 9x-4+5x+16=180^o[/tex]

Combine like terms:-

[tex]\sf 9x+5x-4+16=180[/tex]

[tex]\sf 14x-4+16=180[/tex]

[tex]\sf 14x+12=180[/tex]

Add/Subtract numbers:-

[tex]\sf 14x+12-12=180-12[/tex]

[tex]\sf 14x=168[/tex]

Divide both sides by 14:-

[tex]\sf \cfrac{14x}{14}=\cfrac{168}{14}[/tex]

[tex]\sf x=12^o[/tex]

Answer:

this is the answer

The quarterly interest rate is equal to 2.25%. This implies that Gavin is correct.

Mathematically, the compound interest on an investment can be calculated by using this formula:A(t) = P(1 + r/n)^{nt}

Where:A represents the future value.

r represents the interest rate.

n represents the number of times compounded.

P represents the principal.

T represents the time measured in years.

In this scenario, Gavin's savings account is compounded annually at an interest rate of 9%. This ultimately implies that, the equivalent quarterly interest rate would be calculated by dividing the annual interest rate of 9% by 4 as follows:

Quarterly interest rate = 9/4

Quarterly interest rate = 2.25%

The linear function with values of f(-1)=8 and f(5)=6 is  f(x) = [tex]\frac{-x+23}{3}[/tex].

What is linear function?

 A straight line on the graph has the equation or formula y = f(x) = px + q is linear function .One independent and one dependent variables are present. X and Y are the independent and dependent variables, respectively. P is the y-intercept or constant term, and it also represents the value of the dependent variable. A straight line on the coordinate plane is represented by a linear function.

Here the given  values are f(-1)=8 and f(5)=6.

We know that f(x)=y , Then the points are (-1,8) and (5,6).

Using slope formula ,

=> slope m= [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

=> slope m = -2/6=-1/3

Now using slope formula,

=> [tex]y-y_1=m(x-x_1)[/tex]

=>y-8=-1/3(x+1)

=>3y-24=-x-1

=> 3y=-x+23

=> y = [tex]\frac{-x+23}{3}[/tex]

Hence the linear function is f(x) = [tex]\frac{-x+23}{3}[/tex].

Answer:

y = ±√100-x

Step-by-step explanation:

To work out the inverse of this function :

We solve for x then swap x and y :

Solving for x :

y = 100 - x²

Add x² to both sides :

x² + y = 100

Subtract y from both sides :

x² = 100-y

Square root both sides :

x = ±√100-y

Now we have solved for x. Now swap x and y :

y = ±√100-x

This is our final answer and is the first option.

Answer:

  D(8, -11)

Step-by-step explanation:

You want the coordinates of end point D if C is (2, -3) and the midpoint of CD is M(5, -7).

The midpoint is the average of the endpoint coordinates:

  M = (C +D)/2

Solving for D, we find ...

  D = 2M -C

Then point D is ...

  D = 2(5, -7) -(2, -3) = (2·5-2, 2(-7)+3)

  D = (8, -11)

Based on the equation y = 3x+40 where y is the number of stamps and x is number of weeks after Paul inherited the stamps, the correct statement is since inheriting the collection, Paul has bought 3 new stamps each week.

According to the question,

We have the following information:

y = 3x+40 where y is the number of stamps and x is number of weeks after Paul inherited the stamps

Now, when we observe this equation carefully, we notice that 3x is added to 40. So, it means that 40 is constant. Then, the number of stamps increasing per week is in the multiplication of 3. Or, in other words, 3 new stamps are bought each week.

For 1st week:

y = 3*1+40

y = 43

For 2nd week:

y = 3*2+40

y = 6+40

y =46

Hence, the correct option is C.

The image of the corresponding to each slope is attached

A line's steepness can be determined by looking at its slope.

Slope is determined mathematically as "rise over run" (change in y divided change in x).

assuming slope is m

m = (y₂ - y₁) / (x₂ - x₁) = change in y / change in x

considering the formula

slope is between 0 and 1 when rise (change in y) is so smaller than run (change in x) hence the line is closer to horizontal

slope is greater than 1 then the rise is more than run, in this case the line is approaching vertical line

numbers less than zero are negative hence slope has a negative value

A horizontal line is a line that has a slope of of zero while vertical lines has its slope as infinity

Using the z-score tables, the number of babies that weighed more than 10 pounds is; 43

A probability distribution that can be considered to be symmetric about the mean is the normal distribution, which can often be referred to as the Gaussian distribution. This depicts to us the concept of data being close to the mean occurring more often than data that are considered far from the mean. The normal distribution usually has a bell curve graph.

We are given that;

The total number of babies is 908.

Mean of the normal distribution is 7.2 pounds.

Standard deviation of the normal distribution is 1.5 pounds.

The formula of z score is given by;

z = (x - μ)/σ

where;

x is sample mean

μ is population mean

σ is standard deviation

We are given that;

x = 10

μ = 1.5

σ = 7.2

Thus;

z = (10 - 7.2)/1.5

z = 1.86667

The P-value from Z-Table gives us:

Mr. Pinello wants each container to contain the same number of coloured pencils and markers, the most containers he can create is 16.

What is the Greatest Common Factor?

The biggest positive integer that divides evenly into all the numbers with no remainder is the greatest common factor (GCF, GCD, or HCF) of a collection of whole numbers.

We have,

The number of coloured pencils Mr. Pinello has = 80.

The number of markers and pencils Mr. Pinello has = 60.

The most containers Mr. Pinello can create to ensure that each one contains an identical amount of coloured pencils and markers.

The GCD of the number of coloured pencils and markers will be the largest number of containers to have the same number of items when the same number of items must be preserved.

Calculating the gcd of  and 80 and 64 is:

The greatest common divisor (GCD) of both 80 and 64 is 16.

To have $600,000 for retirement in 35 years at 5% interest, one would need to deposit $528.13 in the account each month.

Periodic deposits are monthly cash inflows into a retirement account that accumulates interest by compounding.

To find periodic deposits, we can use an online finance calculator, defining the parameters as follows.

N (# of periods) = 420 months (35 years x 12)

I/Y (Interest per year) = 5%

PV (Present Value) = $0

FV (Future Value) = $600,000

Results:

Monthly Deposits (PMT) = $528.13

Sum of all periodic deposits = $221,814.60

Total Interest = $378,185.40

Thus, monthly deposits of $528.13 can accumulate to $600,000 in 35 years at 5% interest.

The expression equivalent to [tex]-3(\frac{7}{2} -\frac{2}{3}m )+\frac{17}{2} -m[/tex] is m - 2.

Equivalent expressions are expressions that work the same even though they look different.

In other words, equivalent expressions are expressions that have the same value.

Therefore, the expression that is equivalent can be calculated as follows:

[tex]-3(\frac{7}{2} -\frac{2}{3}m )+\frac{17}{2} -m[/tex]

Hence, let's simplify the expression to find it's equivalent,

open the bracket

[tex]-3(\frac{7}{2} -\frac{2}{3}m )+\frac{17}{2} -m = -\frac{21}{2}+2m+\frac{17}{2}-m[/tex]

[tex]-3(\frac{7}{2} -\frac{2}{3}m )+\frac{17}{2} -m = -\frac{21}{2}+2m+\frac{17}{2}-m = -\frac{21}{2}+\frac{17}{2}+2m-m[/tex]

[tex]-\frac{21}{2}+\frac{17}{2}+2m-m=-\frac{4}{2} + m[/tex] = m - 2
