m 1 = a) 40 b) 130 c)50

Answers

Answer 1

Answer:

C) 50

Step-by-step explanation:

You first look at the 40 given to you. Then you know the angle opposite of it will be 40 also because of the law that opposite angles are the same. Once you have two angles in the triangle you can add 40 plus 90 in which you get 130 but that does not equal 180. So you can see that angle 1 is 50 because 50 and 130 equals 180.

if one score of 39 is changed to 40, how will the histogram change?

Answers

Answer: Histogram of 30-40 becomes slightly low and histogram of 40-50 becomes slightly high.

Step-by-step explanation:

Since we have given that

C.I. Frequency

10-20 1

20-30 4

30-40 15

40-50 14

If one score of 39 changed to 40.

Then it comes under class interval of 40-50

so, frequency under 30-40 becomes 14.

frequency under 40-50 becomes 15.

So, Histogram of 30-40 becomes slightly low and histogram of 40-50 becomes slightly high.

In this case, three "sevens" would go into 22 (7x3=21). Since we have one left over, it would go over the 7! So that final answer would be 3 1/7!

16.) The school that Lisa goes to is selling tickets to the annual talent show. On the first day of ticket sales the school sold 4 adult tickets and 5 student tickets for a total of $102. The school took in $126 on the second day by selling 7 adult tickets and 5 student tickets. What is the price of the adult and the student ticket?

Answers

Answer:

adult tickets are $8 and student tickets are $14

Step-by-step explanation:

to find the price of adult and student tickets, first look at all the given values:

a = adult tickets

s = student tickets

so: 4a + 5s = 102

and : 7a + 5s = 126

since in both equations the number of student tickets are the same, we have to find the difference of value to determine how much adult tickets are:

126-102 = 24

there are 3 more adult tickets in the equation with a total of 126, therefore:

24 / 3 = 8

that means each adult ticket is work 8 dollars.

now substitute this value:

4(8) + 5s = 102

32 + 5s = 102

you can solve this by concluding that 102- 32 is 70

that means 5(s) has to equal 70

so 70 / 5 = s

70/5 = 14

so the value of s = 14 and the value of a = 8

An online retail company tracked total number of purchases monthly. In June 2007 they were 4,500 purchases and in September 2008 there were 5,100. The purchases followed a linear model of the form p = S ( t ) = r t + i where p purchases is in 1000's and t is months where January 2007=0

Answers

The linear model for the number of purchases over time is:

p = 0.043t + 3.726

We have,

Let's assign the variable t as the number of months since January 2007, where t = 0 corresponds to January 2007.

Given data:

June 2007: p = 4,500 (in thousands, so p = 4.5)

September 2008: p = 5,100 (in thousands, so p = 5.1)

We can use these data points to set up a system of equations to solve for the slope (r) and the intercept (i) in the linear model p = rt + i.

Using the data points,

4.5 = r(18) + i (June 2007 corresponds to 18 months after January 2007)

5.1 = r(32) + i (September 2008 corresponds to 32 months after January 2007)

Solving this system of equations will give us the values of r and i.

Subtracting the second equation from the first equation:

4.5 - 5.1 = r(18) - r(32)

-0.6 = -14r

r = -0.6 / -14

r = 0.043

Substituting the value of r into one of the equations:

4.5 = 0.043(18) + i

4.5 = 0.774 + i

i = 4.5 - 0.774

i = 3.726

Therefore,

The linear model for the number of purchases over time is:

p = 0.043t + 3.726

Point D is located on the segment CE. IF CD = 24 and DE = x and CE - 5x, what is the measure of segment CE?

Answers

Answer:

Step-by-step explanation:

If point D is located on the segment CE, then point C, D and E lies on the same line i.e they are collinear. Mathematically, CD+DE = CE

Given CD = 24 and DE = x and CE = 5x, on substituting this values in the equation we have;

[tex]24+x = 5x\\5x-x = 24\\4x = 24\\x = 24/4\\x = 6[/tex]

Since CE = 5x, CE = 5(6) = 30

The measure of segment CE is 30

Justin Launches a water balloon vertically from a platform on his roof height in feet is represented By the equation H = -16t^2+32t+48,where T is the time (in seconds) after he launch is the water balloon

What is the maximum height of the water balloon?

How long does it take to reach its maximum height?

Answers

Answer:

a) 64 feetb) 1 sec

Step-by-step explanation:

Given the height in feet represented by the equation H = -16t²+32t+48, at maximum height, the velocity of the water balloon is zero.

Velocity = dH/dt = 0

dH/dt = -32t+32 = 0

-32t+32 = 0

-32t = -32

t = -32/-32

t = 1sec

Substituting t = 1sec into the modeled equation of the height

H = -16t²+32t+48

H = -16(1)²+32(1)+48

H = -16+80

H = 64 feet

The maximum height of the water balloon is 64 feet

b) In order to know how long it takes to reach its maximum height, we will substitute H = 64 feet into the equation of the height.

64 = -16t²+32t+48

-16t²+32t = 16

16t²-32t+16 = 0

t²-2t+1 = 0

t²-t-t+1 = 0

t(t-1)-1(t-1) = 0

(t-1)² = 0

t-1 = 0

t = 1sec

It took the water balloon 1 sec to reach its maximum height.

14th term of geometric sequence 10,20,40

Answers

Answer: 81920

Explanation: The general formula for nth term in a geometric sequence is an=a1*r^(n-1), where a1 is the first term, r is the common ratio, and n is the position in the term (in this case 14).

To find the common ratio, we can simply divide the next term after the first (20/2=10).

So, an=10*2^(14-1).

After doing the parentheses and multiplication, we have 20^13, which is 81920.

Correct option: First one -> [tex]x^2 = -12y[/tex]

Step-by-step explanation:

The focus and the vertex have the same x-coordinate, so we have a vertical parabola. The standard equation for this parabola is:

[tex]y = a(x-h)^2 + k[/tex]

If the vertex is at the origin, we have that:

[tex](h, k) = (0,0)\\h = 0, k = 0[/tex]

If the focus is at (0,-3), we have that:

[tex](h, k+p) = (0, -3)[/tex]

[tex]p = 1/4a[/tex]

[tex]k + p = -3[/tex]

[tex]1/4a = -3[/tex]

Answer:

Step-by-step explanation:

First, cancel the 3 at the bottom by getting rid of it and changing the 9 to a 3. You can do this because 3 is one third of 9.

With the division property of exponents, you have to subtract 3-2 and you can leave a to the power of 1 on the numerator.

Then, cancel the b's out by getting rid of them.

__________________________________

Hey!!!

Solution,

Cost of 36 toys=$ 20.52

Cost of 1 toy=20.52/36

Now,

Cost of 120 toys= 0.57*120

=$68.4

hope it helps

Good luck on your assignment

______________________________

Answer:

$68.4

Step-by-step explanation:

Let x represent the required cost.

Since the cost is directly proportional to the number of toys:

x : 20.52 = 120 : 36

i.e. x/20.52 = 120/36

x = [tex]\frac{120 * 20.52}{36}[/tex]

x = 10 * 6.84

x = 68.4

∴ The cost is $68.4.
