This week, the art museum gave away 1,200 tickets to the Greco exhibit, which was 150 percent as many tickets as it gave away last week. Martin is trying to figure out how many tickets the museum gave away last week. His work is shown below.

Step 1: StartFraction part Over whole EndFraction = StartFraction 150 Over 100 EndFraction = StartFraction question mark Over 1200 EndFraction
Step 2: 100 times 12 = 1200
Step 3: 150 times 12 = 1800

In what step did Martin make a mistake, if any?
Step 1: Martin should have written his ratio as StartFraction 1200 Over question mark EndFraction.
Step 2: Martin should have divided 1200 by 8.
Step 3: Martin should have added 1200 and 150.
Martin did not make any mistakes.

Answer:

10

Step-by-step explanation:

4 1/2 + 11/2

= 9/2 + 11/2

= 20/2

= 10

Answer:

244.92 square inches

Step-by-step explanation:

You just have to fill in the formula with the information they gave you.

They gave you the diameter for base circle so you divide that number in half to get the radius which is what you need for the formula represent as "r".

r=3

h=10

and you know pi is 3.14

so just plug in the numbers.

SA=2x3.14x3^2+2x3.14x3x10

SA=6.28x9+6.28x30

SA=56.52+188.4

SA=244.92

Answer:

=4p^2−12p+13

Step-by-step explanation:

Let's simplify step-by-step.

4p^2−12p+13

There are no like terms.

Answer:

x = (6[tex]\sqrt{2}[/tex])/(4[tex]\sqrt{2}[/tex] -3)

Step-by-step explanation:

sin60 degree = [tex]\sqrt{3}[/tex] /2

cos30 degree = 1/2

tan 45 degree =  sin45 degree / cos45 degree = ([tex]\sqrt{2}[/tex]/2)/([tex]\sqrt{2}[/tex] /2) = 1

cot 30 degree = cos30 / sin30 = ([tex]\sqrt{3}[/tex] /2)/(1/2)  = [tex]\sqrt{3}[/tex]

so, let us plug the above values in the given eqution and solve for x

3([tex]\sqrt{3}[/tex] /2 ) + x(1/2) *1 = x([tex]\sqrt{3}[/tex])

3([tex]\sqrt{3}[/tex] /2 )  = x([tex]\sqrt{3}[/tex]) -x(1/2)

3([tex]\sqrt{3}[/tex] /2 )  = x(([tex]\sqrt{3}[/tex])-(1/2)) (by taking x as a common factor)

3([tex]\sqrt{3}[/tex] /2 ) = x(((2[tex]\sqrt{3}[/tex])-(1))/2))    (making the same common denominator

now devide both sides by (((2[tex]\sqrt{3}[/tex])-(1))/2))

x  = 3([tex]\sqrt{3}[/tex] /2 )  / (((2[tex]\sqrt{3}[/tex])-(1))/2))

x = 3([tex]\sqrt{3}[/tex] ) / ((2[tex]\sqrt{3}[/tex])-(1))

Answer:

12°

Step-by-step explanation:

As we can see the triangles are congruent so

< F = < C ( being corresponding angles of congruent triangle)

< C = 29

Now

<A +<B + <C = 180° { being sum of angles of triangle }

5x + 1 + 90 + 29 = 180°

5x = 180° - 120°

5x = 60°

x = 12°

Answer:

intercept = (1,2)

Step-by-step explanation:

[tex] \red{20 \: \frac{1}{4} \div 9}[/tex]

[tex] = \frac{81}{4} \div 9[/tex]

[tex] = \frac{^{9}\cancel{81}}{4} \times \frac{1}{\cancel{9}^{1} } [/tex]

[tex] = \frac{9}{4} [/tex]

[tex] \blue{ = \boxed{2 \: \frac{1}{4} }}[/tex]

Answer:

so um try The y-intercept represents a starting salary of $ 3,000 for a new employee.

The slope represents an additional $ 2,500 in salary for each additional year of employment.

If the starting salary for a new employee is changed to $35,000 and the salary increase is unchanged, the new equation would be y= 2,500x + 35,000

If the yearly salary increase is changed to $ 2,500 . the new equation would be y= 3,000

Answer: x = 1 and y = -1

Step-by-step explanation:

Since both equations are equal to y, that means the equations are both equal to each other

5x - 6 = -4x + 3

Solve for x how you would traditionally do it with any other one-variable equation

9x = 9

x = 1

Plug the now known x value into either equation and you will get your y value.

5(1) - 6 = -1

-4(1) + 3 = -1

Answer:

54

Step-by-step explanation:

1. A = 6 x 9

A = 54

Answer:

heyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy

ok i think this is right

Using the SA formula you'll have to substitute in the edge length for s.

SA = 6(312)²

SA = 584064

The surface area is 584,064 feet²

Answer: b=75

Step-by-step explanation: Given that the health club charges $30 per month, we know that this is the "m" varible. We know this because the total value changes as the value of x changes. The value of b would therefore be $75 dollars because it is a constant and a one time fee. The person joining the health club pays an amount of money per month, as well as an initial charge of $75.

Hope that helps!

I had this question yester day.

Step-by-step explanation:

Answer:

[tex]3\left(5+4y\right)+8-2y=10y+23[/tex]

Step-by-step explanation:

Given

As the expression is given by

[tex]3(5+4y)+8-2y[/tex]

To determine

Simplify the expression

Let us simplify the expression

[tex]3(5+4y)+8-2y[/tex]

Expand 3(5 + 4y) = 15 + 12y

[tex]3\left(5+4y\right)+8-2y=15+12y+8-2y[/tex]

grouping like terms

                              [tex]=12y-2y+15+8[/tex]

                              [tex]=10y+23[/tex]

Therefore,

[tex]3\left(5+4y\right)+8-2y=10y+23[/tex]

Answer:

5

Step-by-step explanation:

To find the missing leg, we need to use a^2 + b^2 = c^2.

Let's call the missing leg a, and then substitute the numbers the other numbers

a^2 + 12^2 = 13^2

Simplify

a^2 + 144 = 169

To solve, subtract 144 from both sides (169-144)

a^2 = 25

This means that a squared is 25; to find a, we need to find the square root of 25.

a = 5

Your answer is 5.

Answer:

5m

Step-by-step explanation:

set it up

[tex]12^{2}[/tex]+[tex]a^{2}[/tex]=[tex]13^{2}[/tex]

do what you know

equation becomes: 144+[tex]a^{2}[/tex]=169

subtract both sides by 144

equation becomes [tex]a{2}[/tex]=25

square root both sides

equation becomes: a=5

The required domain of the function is all real numbers except -5 and 7. Option C is correct.

Given that,
f(x) = (x + 6)  /[(x-7)(x+5)]

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

here,
Given function,
f(x) = (x + 6)  /[(x-7)(x+5)]
We can put any real number on the number line except 7 and -5, because at these value function gives the value as infinity.

Thus, the required domain of the function is all real numbers except -5 and 7. Option C is correct.
