Answer:

It is the first answer choice i believe.

Step-by-step explanation:

There is no way for the bottom line y to be the same as the other side. It has to be smaller since the angles are not the same.

Answer:

m=[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Gladly!

To find the slope, we need to find the change between point a and point b

With the difference between x1 and x2 being 4, and the difference between y1 and y2 being 1, we get a fraction that looks like this,

[tex]\frac{1}{4}[/tex]

This right here is the slope of the line. Hope this helps!

Answer:

29

Step-by-step explanation:

20^2 times 3.14= 1256

21^2 times 3.14= 1384.74

the sum of those two is 2640.74

the square root of that is 29

The radius of the circle is 29 cm.

We have the circle whose area is equal to the sum of the areas of two circles whose radii are 20cm & 21cm.

We have to find the radius of the circle.

Let the radius of the circle be x.

We know that the area of the circle is [tex]\pi r^{2}[/tex]. Then -

[tex]\pi x^{2} =\pi r^{2} +\pi R^{2} \\x=\sqrt{r^{2} + R^{2}} \\[/tex]

Now, in the question given to us -

r = 20cm  and R = 21cm  and 'x' denotes the radius of the circle we have to find.

Substituting the values in the above formula, we get -

x = [tex]\sqrt{400+441}[/tex]

x =29 cm

Hence, the radius of the circle is 29 cm.

Answer:

Part b.

Step-by-step explanation:

Ok, so I think what you can do for part b. is pretty simple. You know that $820 is for 4 weeks of work. 820/4 = 205. So he gets $205 per week. If 820 = 100%, then 205*3 = 75%. So the answer would be he will recieve 75% of his usual pay, and that will be $615.

Answer:

25 4-point questions and 75 2-point questions

Step-by-step explanation:

Let x = no. of 4-point questions

Then 3x = no. of 2-point questions

So, x + 3x = 100

4x = 100

x = 25 =  no. of 4-point questions

and 3x =  3(25) = 75 = no. of 2-point questions

Answer:

78

Step-by-step explanation:

1 metre of plastic sheet= 25 1/2

3 1/17 plastic sheet = x

Cross multiply

x = 3 1/17 × 25 1/2

x = 52/17 × 51/2

x = 2652/34

x = 78

Hence the price of 3 1/17 metre of plastic is ¥78
