Answer:

50 tickts

Step-by-step explanation:

We want to spread 1,000 tickets equally over 20 concerts. This calls for division

1000/20=50

50 tickets are sold each concert

Answer: parallel because the slopes are the same

Step-by-step explanation:

Okay so if the regular price of the shirt is 100% as $25 and you have a 30% discount you are still paying 70% (100-30=70) so 70% as a decimal is .70 and $25 x .70 is $17.50. Therefore the shirt is $17.50 after the discount.

Alright so, what it’s basically asking for is 70% of 25. This is the price of the shirt after you’ve accounted for the 30% discount

Then you would multiply 25 by .70, giving you $17.50

just open the bracket and do algebra. the answer should be C

After 3 seconds and at 60 feet, the bolt hit the elevator if the height in feet after t second is given by the formula h(t)=20t.

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

As we know, the formula for the roots of the quadratic equation is given by:

[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]

When the bolt hit the elevator, they would be at the same height.

∴ 16t²+200 = 20t

16t² -20t + 200 = 0

It is a quadratic equation:

a = 16, b = -20, and c = 200 plug this values in the formula.

After calculating, we will get:

t = -4.2 or t = 3

Time cannot be negative.

So t = 3 seconds

And height h(3) = 20(3) = 60 feet

Thus, after 3 seconds and at 60 feet, the bolt hit the elevator if the height in feet after t second is given by the formula h(t)=20t.

Answer:

X = -10

Step-by-step explanation:

Adding negative ten and ten results in zero, and zero multiplied by anything is, of course, still zero.

(-10 + 10) * (-10 + 10) = 0

0 * 0 = 0

X=-10

Because (x+10)(x+10)=0

So it becomes (x+10)^2=0

And therefore x=-10

Answer:

Step-by-step explanation:

The segment 20.2 cm is the tangent. Therefore x and 20.2cm are perpendicular.

Use the Pythagorean theorem:

[tex]leg^2+leg^2=hypotenuse^2[/tex]

We have

[tex]leg=x,\ leg=20.2cm,\ hypotenuse=(14.7+x)cm[/tex]

Substitute:

[tex]x^2+20.2^2=(14.7+x)^2[/tex]           use (a + b)² = a² + 2ab + b²

[tex]x^2+408.04=14.7^2+(2)(14.7)(x)+x^2[/tex]          subtract x² from both sides

[tex]408.04=216.09+29.4x[/tex]        subtract 216.09 from both sides

[tex]191.95=29.4x[/tex]         divide both sides by 29.4

[tex]x\approx6.5\ cm[/tex]

Answer:

C) Multiply 3x by 6 in the first equation and subtract the second equation.

Step-by-step explanation:

We have been given a system of equations.[tex]3x+3y = 4[/tex] and [tex]18x-9y = 12[/tex]. We are asked to choose the "incorrect" step that will make "not" produce a system with the same solution.

Let us see our give choices one by one.

A) multiply the first equation by 6 and subtract the second equation.

When we will multiply 1st equation by 6, the coefficient of x would be 18. When we will subtract 2nd equation the both x's will cancel out. Therefore, option A is correct.

B) multiply the first equation by −6 and add the second equation.

When we will multiply 1st equation by -6, the coefficient of x would be -18. When we will add 1st equation to 2nd equation the both x's will cancel out. Therefore, option B is correct as well.

C) Multiply 3x by 6 in the first equation and subtract the second equation.

We need to remember that we cannot multiply only one term of equation by some quantity as it will make the whole equation false, therefore, option C is incorrect.

Answer:

25%

Step-by-step explanation:

% increase = (3.50 - 2.80)/(2.80) x 100

= 25% increase

The required percent increase of the price of a bag of bagels from $2.80 to $3.50 is 25%.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
To find the percent increase of the price of a bag of bagels, we can use the formula,

percent increase = [(new value - old value) / old value] x 100%

In this case, the old value is $2.80 and the new value is $3.50. Substituting these values into the formula, we get:

percent increase = [(3.50 - 2.80) / 2.80] x 100%

percent increase = (0.70 / 2.80) x 100%

percent increase = 0.25 x 100%

percent increase = 25%

Therefore, the percent increase in the price of a bag of bagels from $2.80 to $3.50 is 25%.

There are 720 different 6-letter arrangements that can be formed using the letters in the word QUASAR, calculated by 6 factorial (6!).

The question asks for the total number of different 6-letter arrangements that can be formed using the letters in the word QUASAR. This is a problem of permutations where all the letters are distinct. To find the number of different permutations of the letters in QUASAR, we multiply the number of choices available at each position. There are 6 choices for the first letter, 5 for the second, and so on, until 1 choice for the last letter.

Therefore, the permutations are calculated as 6 × 5 × 4 × 3 × 2 × 1, which is equal to 6! (6 factorial).

The calculation of 6! is as follows:

So, there are 720 different 6-letter arrangements that can be formed from the word QUASAR.

The house is 10 units far from the base of the ladder?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that

length of ladder = 26 feet

And height of house = 24 feet

According to given scenario it will form a right angled triangle.

In which the length of ladder is hypotenuse

Height of house be perpendicular

And base we have to calculate.

We know that the Pythagoras theorem for a right angled triangle:

(Hypotenuse)²= (Perpendicular)² + (Base)²

Now plug the values

(26)²= (24)² + (Base)²

(26)²= (24)² + (Base)²

676  =  576 + (Base)²

(Base)² = 100

  Base = 10 units

Thus, the base is of 10 units.

Answer:

I believe the answer would be C.

Step-by-step explanation:

First, simply look at the roots of each answer choice. A rational number is any number that can be written as a fraction.

In the first option choice [A.], the square root of 8 is 2.8284.... a long decimal that continues for a whi;e. So, it can't be written as a fraction.

In the second option choice [B.], the square root of 24 is 4.8989.... another long decimal that continues for a while. So, it can't be written as a fraction.

In the third option choice [C.], the square root of 81 is 9. 9 can be written as a fraction [for example 27/3] So it's the correct answer.

In the last option choice [D.], the square root of 2 is 1.4142.... another long decimal that continues for a while. So, it can't be written as a fraction.

Answer:

There are infinitely many solutions.  It is the same line.

Step-by-step explanation:

If you start by multiplying the first equation by 2 to get rid of the fractions, you get -x + y = -2.  If you solve it for y, you get y = x - 2.  The second equation can be solved for y also, giving you y = x - 2.  That means they are the same line and the solution to this situation is infinitely many solutions because all the points on one line are identical to the points on the other line because they are the same line.

The function is linear

Step-by-step explanation:

* Lets check from the table the type of the function

- At first check if it is linear or not

- The points are:

  (165 , 198) , (168 , 201.6) , (170 , 204) , (172 , 206.4) , (175 , 210)

* Find the slope for each two points if the value of the slop is

 constant, then the function will be linear

∵ The slop = (y2 - y1)/(x2 - x1)

∴ m1 = (201.6 - 198)/(168 - 165) = 1.2

∴ m2 = (204 - 201.6)/(170 - 168) = 1.2

∴ m3 = (206.4 - 204)/(172 - 170) = 1.2

∴ m4 = (210 - 206.4)/(175 - 172) = 1.2

∵ m1 = m2 = m3 = m4

# Note: You can use any to points to find the slope you will

  have the same value

∴ The graph of the points is a line with slope 1.2

* The function is linear

Answer:

A linear function is the best model.

The ratio of y to x for the ordered pairs is constant, so the relationship is a direct variation. A direct variation is a type of linear function.

Answer:

His money earned $36 after 3 months

Step-by-step explanation:

* Lets revise the rules of simple interest

- Simple Interest Equation (Principal + Interest)

 A = P(1 + rt)

- Where:

• A = Total amount (principal + interest)  future amount

• P = Principal Amount

• I = Interest Amount

• r = Rate of Interest per year in decimal; r = R/100

• t = Time Period involved  

* To calculate the interest I use the formula

  I = P × r × t

* Lets solve the problem

- The rate is annual

- The interest calculated after 3 months

∴ I = P × R/100 × t/12

∵ P = $3600.00

∵ R = 4%

∵ t = 3 month
