What is the measure of angle 7?​

The Measure Of Angle 1 Is (3x + 10) In The Measure Of Angle 4 Is (4x - 15)What Is The Measure Of Angle

Answers

Answer 1

∠1 = ∠4 ( vertically opposite angles )

Then :-

[tex]3x + 10 = 4x - 15[/tex]

[tex]10 = 4x - 15 - 3x[/tex]

[tex]10 = 1x - 15[/tex]

[tex]1x - 15 = 10[/tex]

[tex]1x = 10 + 15[/tex]

[tex]1x = 25[/tex]

Which means :-

∠1 =

= 3x + 10

= 3 × 25 + 10

= 75 + 10

= 85°

∠4 =

= 4x - 15

= 4 × 25 - 15

= 100 - 15

= 85°

Then :-

∠7 = ∠6

∠6 + ∠4 = 180° ( interior angles on the same side of transversal )

∠6 + 85 = 180°

∠6 = 180 - 85

∠6 = 95°

As ;

∠6 = ∠7

∠7 = 95°

Therefore , angle 7 = 95° .

The equation below can be used to determine I, the am

simple interest on a loan.

I= prt, where p is the principal, r is the rate of the loan,

the length of the loan in years.

Which of these is the equation solved in terms of r?

Answers

Given :

The equation below can be used to determine I (simple interest) on a loan as follows :

[tex]I=Prt[/tex] ...(1)

P is principal, r the rate of the loan,  t is the length of the loan in years.

We need to find the equation to solve in terms of r. We can find the value of P.

Dividing both sides of equation (1) by rt. So,

[tex]\dfrac{I}{rt}=\dfrac{Prt}{rt}\\\\P=\dfrac{I}{rt}[/tex]

So, P can be solved as : [tex]P=\dfrac{I}{rt}[/tex].

A hole is accidentally made in a water tank. On the first day, 32 gallons of water leak from the tank. Each day after that, workers are able to decrease the number of gallons leaking by 8% of the leakage on the day before. What is the total number of gallons of water that leaked from the tank?

Answers

Answer: 34.78 gallon

Step-by-step explanation:

Exponential equation for decay:

[tex]A=P(1-r)^t[/tex] , where p = initial amount, r= rate of decay , t= taime

As per given,

r= 8% = 0.08

For days 1 , i.e. at t= 0 , P= 32 gallons

[tex]1=32(1-0.08)^t\\\\\Rightarrow\ \dfrac{1}{32}=(1-0.08)^t \\\\\Rightarrow\ \ln \left(\frac{1}{32}\right)=t\log (0.92)\\\\\Rightarrow\ t=-\frac{5\ln \left(2\right)}{\ln \left(0.92\right)}=41.5\approx42[/tex]

Total water = [tex]\dfrac{a(1-r^n)}{1-r}=\dfrac{32(1-0.08^{42})}{1-0.08}=34.782[/tex]

hence, the the total number of gallons of water that leaked from the tank = 34.78 gallon approx.

Find the minimum or maximum value of the function y=9x2+7. Describe the domain and range of the function, and where the function is increasing and decreasing. The minimum value is Response area. The domain is Response area and the range is Response area. The function is decreasing to the Response area of x= Response area and increasing to the Response area of x= Response area.

Answers

The given function is [tex]y=x^2+7[/tex].

Minimum or maximum value:

At the extremum (maximum or minimum) value, the function will have zero slope. So, differentiate the given function once and equate it to zero to get the extremum point.

dy/dx=0

[tex]\Rightarrow 18x=0\cdots(i)[/tex]

[tex]\Rightarrow x=0[/tex]

Now, check whether the point x=0 is corresponding to the maximum value or minimum value by differentiating the function twice,

[tex]\frac {d^2y}{dx^2}=18[/tex]

As [tex]\frac {d^2y}{dx^2} >0[/tex] for all value of x, so x=0 is the point corresponding to minima.

Put x=0 in the given function to get the minimum value.

[tex]y_{min}=9(0^2)+7[/tex]

[tex]y_{min}=7[/tex]

Domain and range:

The function defined for all the values of the independent variable, x.

So, the domain is [tex](-\infty, \infty)[/tex].

The range of the function is the possible value of y.

The minimum value, for x=0, is y=7.

The maximum value, as [tex]x\rightarrow \infty \;or\; -\infty, y\rightarrow \infty[/tex].

Hence the range of the function is [tex][7,\infty)[/tex].

The value of x for which the function is increasing and decreasing:

If the slope of the function is negative than the function is decreasing, so

Then, from equation (i), the value of x for which dy/dx<0,

18x<0

[tex]\Rightarrow x<0[/tex]

Hence, the function is decreasing for [tex]x\in {-\infty, 0)[/tex] .

While if the slope of the function is positive than the function is increasing, so

Then, from equation (i), the value of x for which dy/dx<0,

18x>0

[tex]\Rightarrow x>0[/tex]

Hence, the function is increasing for [tex]x\in {0,\infty)[/tex]

Answers

Answer:

4.5 in. is equivalent to 337.5 ft.

Step-by-step explanation:

The given parameters are;

The scale of the scale map is 2 in. to 150 ft.

The measured length on the scale map = 4.5 inches

The actual distance of the location is given as follows;

2 in. is equivalent to 150 ft.

Therefore;

1 in. is equivalent to 150 ft./2 = 75 ft.

4.5 in. will be equivalent to 4.5 × 75 ft. = 337.5 ft.

4.5 in. will be equivalent to 337.5 ft.

2. Tyler is solving this system of equations:
4p + 2g = 62
8p - q = 59

He can think of two ways to eliminate a variable and solve the system:

o Multiply 4p + 2g = 62 by 2, then subtract 8p - q= 59 from the result.

• Multiply 8p-q=59 by 2, then add the result to 4p + 2q = 62.

Do both strategies work for solving the system? Explain or show your reasoning.

please help out ://

Answers

Answer:

Both of them work

Step-by-step explanation:

by multiplying the first equation by 2 it creates the same coefficient in front of "p" for both equations. same for the second equation and "q".

Both strategies works since we can easily eliminate a variable from both equations.

Given the simultaneous equation solved by Tyler

4p + 2q = 62

8p - q = 59

In order for him to eliminate a variable to solve the system of equations, he must ensure that the coeffiecient of the variable to be eliminated are equations in both expressions. To do that;

Multiply 4p + 2g = 62 by 2, then subtract 8p - q= 59 from the result. This will give;

8p + 4g = 124

8p - q = 59

Subtract

4q + q = 124 + 59

5q = 183

The second required strategy is  to Multiply 8p-q=59 by 2, then add the result to 4p + 2q = 62, to have:

16p-2q=118

4p + 2q = 62

Adding up

16p + 4p = 118 + 62

20p = 180

p = 9

We can see that both strategies works since we can easily eliminate a variable from both equations.

sorry i couldnt find my work for this problem but i hope it helps !

An equation is formed of two equal expressions. When in the given equation the value fo b is d/(f+3).

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

fb + 3b = d

Take b as a common term from both the terms on the left side of the equation,

b(f + 3) = d

Divide both the sides of the equation by (f+3),

b(f + 3)/(f+3) = d/(f+3)

Simplify,

b = d/(f+3)

Hence, when in the given equation the value fo b is d/(f+3).

A secretary earns $12 an hour and worked a total of 47 hours last week she earns time and a half for work beyond 40hours calculate her pay

Answers

Answer:

$606

Step-by-step explanation:

For the first 40 hours, she was making $12. With this, we can do 12x40, which is 480$. We can store that in a safe space for later access. Afterwards, since the problem says that "after 40 hours she earns time and a half for her work" we can assume she gets 1.5x her pay after 40 hours, which is $18 (We can get this by 12 / 2 = 6. Then do 12 + 6 = 18). Then we can do 18x7 because she worked 7 hours over 40. With that, we get 126$. Now we can do 480$ + 126$ = 606$. So, she earned 606$.

A triangle has two sides of length 19 and 3. What is the largest possible whole number length for the third side?

Answers

Answer:  21

========================================================

Explanation:

Consider a triangle with side lengths a,b,c such that a < b < c

a = 3 and b = 19 are the two known sides

Let c be the missing side length

The missing side has the property that...

b-a < c < b+a

19-3 < c < 19+3

16 < c < 22

Meaning that if c is a whole number then it can take on any of these values {17, 18, 19, 20, 21}

So c = 21 is the largest possible third side, where only whole number sides are considered.

We can't have a third side of 22 because the two other sides add to a+b = 3+19 = 22 and a triangle wouldn't form (instead only a straight line would). I recommend cutting out strings of paper trying this out yourself.

---------------

Side note: The inequality b-a < c < b+a is a variation of the triangle inequality theorem.
