can someone help please?

Answers

Answer 1

Answer:

a. 90 degrees (given)

b. 270 degrees (360-90)

c. 16π (Circumference= diameter * π, diameter= 2r= 2(8)=16, so c= 16*π)

d. 4π (That section is a semicircle, so length should be 1/4 the circumference)

e. 12π (This section is 3/4 the circumference)

f. 64π (Area= πr^2, and r^2= 8^2= 64, so 64π)

g. 16π (That section is 1/4 the area)

The area of the sector which is the white triangle adding the shaded region is 68.9/360*π*9.28^2=51.78005(rounding to 5th digit after decimal point for accuracy before we do final round for answer)

The area of the white triangle in the sector has area 1/2*9.28^2*sin(68.9)= 40.17223(rounding to 5 digits again for some accuracy.

Now we take out the white triangle from the sector.

51.78005-40.17223=11.60782

rounding to the nearest tenth we get 11.6 cm^2

Problem done!

How do you simplify 4ab + 13bc

Answers

Answer:

you cant

Step-by-step explanation:

its already simplified from the way its written

b(4a + 13c) is the simplified form of the expression 4ab + 13bc

To simplify the expression 4ab + 13bc, we can factor out the common term "b" from both terms:

4ab + 13bc = b(4a + 13c)

By factoring out the common term "b", we obtain the simplified form b(4a + 13c).

This represents the original expression in a more concise and factored form.

Hence, the simplified form of the expression 4ab + 13bc is b(4a + 13c) by taking the common term b

What is the value of z?

Answers

Answer:23

Step-by-step explanation:

Answer:

z = 23

Step-by-step explanation:

The angles in a triangle add up to 180°.

So, 62° + 95° + z = 180°.

Subtract 62 and 95 on both sides.

62 + 95 + z - 62 - 95 = 180 - 62 - 95

z = 23

85 degrees

Step-by-step explanation:

If you find the missing angle for the triangle it would be 95 because 60+25 is 85 then 180-85 is 85. For a straight line you have to have 180 degrees, so you know the first angle is 95 degrees so the second one would have to be 85 degrees :)

I need help on number 8

Answers

Answer:

y=4x

Step-by-step explanation:

y=mx+b is our frame equation for a linear function.

b=the y intercept, or when the line crosses the y axis, whenever x=0, so in this chart it is (0,0), b=0

y=mx+0

m= the slope, to find m you can either use the slope formula or plug in a point and solve for m

8=m(2) + 0

m=4

we don't need to put 0 in our final answer because it doesn't change anything

Student Council held a bake sale to raise money for the local food pantry. They sold a total of 40 items which included pies and cakes. Pies were $10 each and cakes were $8 each. They raised $356. How many pies and how many cakes did they sell?

Answers

Answer: 18 pies, 22 cakes

Step-by-step explanation:

Let the number of pies sold be represented by p.

Let the number of cakes be represented by c.

The information in the question can then be represented in an equation as:

p + c = 40 ........ i

10p + 8c = 356 ....... ii

Multiply equation i by 10

Multiply equation ii by 1

10p + 10c = 400 ....... iii

10p + 8c = 356 ....... iv

Subtract iv from iii

2c = 44

c = 44/2

c = 22

22 cakes were sold

Since 40 items were sold, the number of pies sold will be:

= 40 - 22

= 18 pies
