Answer:

wouldn't they both be 88

I'm not sure if that's correct though

Answer:

x = 88

y = 88

Step-by-step explanation:

66 + 26 + x = 180 (collect like terms)

92 + x = 180 (subtract 92 on both sides)

x = 88

y = x

y = 88

They are vertical so their measures are the same.

Hope this helps ya!!

Answer:

67%

Step-by-step explanation:

This is because 67% is basically 67/100 as a fraction and 3/5 is only 60%, all you need to know is the facts about fraction to percentage

Answer:

39.27

Step-by-step explanation:

The area of a semi-circle is pi times the radius squared divided by 2. So basically standard area of a circle formula (pi times the radius squared) but then you add in the extra step of dividing it by 2.

The formula looks like this:

π × r² ÷ 2

The radius is half the diameter of the circle. So basically think of it as a line to the middle of the circle. Our diameter is 10, (the diameter is the entire length of the circle. It gives us this already. If you need diameter and only have the radius add the radius together twice or multiply it by 2 to get the diameter. Fun fact..?)

and it tells us to substitute pi for 3.142.

So, plugging our numbers in we get:

3.142 x 5^2 ÷ 2 = 39.275.

Cut out the 3rd decimal place (5) as it tells us to only include the first 2 decimal places, and we finally end up with 39.27.

Hope this helps and have a nice day!

Answer:

y=[tex]\frac{9}{2\\}[/tex] x-13

Step-by-step explanation:

first, since it's parallel the slope has to be the same and the y-intercept has to be different.

you will have y=9/2x+b

find b, by using the points you are given so you will get

-4=(9/2) times (2)+b.

then when sloving you will get b=-13 and so the full equation will be

y=9/2x-13

Step 2: Solve for n

Answer:

a) 1/10

b) 1/2

c) 1/2

d) 2/5

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur.

Probability = Total event/Total sample space

Since there are ten ball in the bag numbered 1 to 10

S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

n(S) = 10

Total sample space = 10

a) If we are to get the probability of picking the number 7.

(E) = {7}

n(E) = 1

Event = 1

Pr(picking 7) = 1/10

b) a) If we are to get the probability of picking an odd number

(E) = {1, 3, 5, 7 , 9}

n(E) = 5

Event = 5

Pr(an odd number) = 5/10 = 1/2

c) a) If we are to get the probability of picking an even number

(E) = {2, 4, 6, 8,10}

n(E) = 5

Event = 5

Pr(an even number) = 5/10 = 1/2

d) a) If we are to get the probability of picking prime

(E) = {2, 3, 5, 7}

n(E) = 4

Event = 4

Pr(prime) = 4/10 = 2/5

Answer:

Answer:

The equation would be if y is the numbers in the sequence (like 3, 9, 27) and x is the is the number in the order (like 3 is 1, 9 is 2, 81 is 4) the the equation would be y = 3^x.

Answer:

-0.25

Step-by-step explanation:

xD im a bit late :P

we can pick any 2 points on the line.

let's pick, (-1, 2) and (-3, 1)

Alright, so the formula to calculate slope is in the attachment below.

If you're a bit confused on what the little 2 and 1 at the bottom of each of those numbers are representing the points. So let's say (-3, 1) is point 2. And (-1, 2) is point 1.

the variable "y" is the y-coordinate.

the variable "x" is the x-coordinate.

And all we need to do now is just sub in the values and that's your answer.

so we have the 2 y-coordinates, 1 and 2.

We subtract them. 1-2=-1

then we have the 2 x-coordinates, -1, -3

-1-3=-4

so -1/-4 is -0.25

I am not sure if this is right -___- but this is what I've been taught sooooo :?

Answer:

I'm pretty sure it's B.

Step-by-step explanation:

The more experience you have, the better you are at your job. If your doing better at your job, you get better pay.

Good luck on the test BTW. =)

The correct answer is option B which is the hourly pay usually increases with the work experience.

Scatter plots are graphs that show how two variables in a data collection relate to one another. On a two-dimensional plane or in a Cartesian system, it represents data points.

In the given graph horizontal axis contains the years of experience and the vertical axis consists of the hourly pay of an employee. We can see that the employees with higher experience are paid a higher hourly amount.

Therefore the correct answer is option B which is the hourly pay usually increases with the work experience.

Answer:

346.88 meters

Step-by-step explanation:

Given that the area of the square-shaped terrain is 470 square meters.

Let a be the side of the terrain, so

Area of the square-shaped terrain, [tex]a^2=470[/tex] square meters.

Therefore, the length of one side, [tex]a=\sqrt {470}=21.68[/tex] meters.

The length of single thread wire required in circulating the square-shaped terrain = the perimeter of the square-shaped terrain

As the perimeter of a square having side a = 4a

So, the length of single thread wire required in circulating the square-shaped terrain= 4 x 21.68 =86.72 meters

Therefore, the length of 4 thread wire required in circulating the square-shaped terrain= 4 x 86.72=346.88 meters.
