Frank earns $8 per hour. Madison
earns $7.50 per hour. Frank started working after Madison had already earned $300. If these rates continue, will Frank’s earnings ever equal Madison’s earnings? If so, when?

Answers

Answer:

yes, and at 600 hours they are equal and at 601 Frank passes her.

Step-by-step explanation:

since frank  has a higher salery/slope and Madison has a lower salary slope meaning even though Madison started out with more Frank will eventually pass her.

First, you gotta find the difference slope 8-7.5 so .5 then find the difference in starting points 300 and zero. then multiply the difference as a  positive(make it reversed 1/2 to 2/1 ) so 2 times 300 equals 600.

Answer:

They will and it will be by the 600th hour. The equation is frank makes 8$ dollars per hour for n hours. That (at some point) is the same as what maddi makes, 7.50 per hour for n hours plus 300... sooo

8n=7.50n+300

Sub in n for 600 and it should cancel everything out and work :)

Answer:

x = 2 , y =  38

x =  3 , y = 42

x = 4 , y = 46

x = 5 , y = 50

Step-by-step explanation:

The solution for the equation at different values is given below:-

x =  3 , y = 42

x = 4 , y = 46

x = 5 , y = 50

What is a linear equation?

A linear equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Given that the equation is y= 4x +30. From the table, the value of y at different values of x will be:-

x =  3 , y = ( 4 x 3) + 30 =  12 + 30 = 42

x = 4 , y = ( 4 x 4 ) + 30 = 16 + 30 = 46

x = 5 , y = ( 4 x 5 ) + 30 = 20 + 30 =  50

Therefore, the solution for the equation at different values is at x =  3 , y = 42 then at x = 4 , y = 46 and, at x = 5 , y = 50.

When a transversal intersects two parallel lines, eight angles are formed.

The angles which are in the same position on same side of each line intersected by the transversal, are called corresponding angles.

Corresponding angles are congruent.

So,

Angle 6x+4° and 100° will be congruent or equal

[tex]6x+4 = 100\\6x =100-4\\6x = 96\\\frac{6x}{6} = \frac{96}{6}\\x = 16[/tex]

A piece of string has been used to measure the circumference of a circle. Use a ruler to measure the diameter of the circle and the length of the string to the nearest 1/4 inch

Answers

Answer:

The circumference is expressed usingC=2πr

Step-by-step explanation:

This problem is on the mensuration of flat shapes, a circle.

The length of the string corresponds to the circumference of the circle.

The lenght of the string can be calculated by using the expression for circumference, if after using the ruler to obtain the diameter "d"

upon measuring the diameter we can further obtain the radius "r"

The expression for the radius is r=d/2 (the radius is half the diameter)

C=2πr

where pi= 3.124 a constant term

Hence Circumference is the same as the length of the string

A number divided by 42 has a quotient of 28 with a remainder of 4. What is the number?
O 1,064
o 1,172
O 1,176
O 1,180

Answers

Answer:

D. 1,180

Step-by-step explanation:

Given the following data;

Divisor = 42

Quotient = 28

Remainder = 4

A quotient of 28 simply means that a number divided by 42 would have a value that is equal to 28 without any remainder.

Let the unknown number be X

X = (42*28) + 4

X = 1176 + 4

X = 1180.

Method II

Y/42 = 28

Cross-multiplying, we have;

Y = 28 * 42

Y = 1176

Given that the remainder is 4

X = Y + 4

X = 1176 + 4

X = 1180.

Therefore, the number is 1180.

if X=14 and y=-6 and z=1 find the value

Step-by-step explanation:

g(x) = 2x² - 6x - 56 ← factor out 2 from each term

      = 2(x² - 3x - 28) ← factor the quadratic

Consider the factors of the constant term (- 28) which sum to give the coefficient of the x- term (- 3)

The factors are + 4 and - 7, since

4 × - 7 = - 28 and 4 - 7 = - 3 , thus

x² - 3x - 28 = (x + 4)(x - 7) , then

g(x) = 2x² - 6x - 56 = 2(x + 4)(x - 7) → B

Answers

Given:

In an asteroid field, 75% of the asteroids are carbonaceous asteroids.

There are 375,000 carbonaceous asteroids in the asteroid field.

To find:

The number of asteroids that are not carbonaceous.

Solution:

Let the total number of asteroids be x.

According to question,

[tex]75\%\text{ of }x = 375000[/tex]

[tex]\dfrac{75}{100}x=375000[/tex]

[tex]0.75x=375000[/tex]

Divide both sides by 0.75.

[tex]x=\dfrac{375000}{0.75}[/tex]

[tex]x=500000[/tex]

Asteroids not carbonaceous = Total asteroids - Carbonaceous asteroids

                                                [tex]=500000-375000[/tex]

                                                [tex]=125000[/tex]

Therefore, 125,000 asteroids are not carbonaceous.
