C. 68°
D. 74°

Answer:

Basic fact:

area of a triangle = b x h /2

Step-by-step explanation:

we know the three main values

10mm

8mm

8mm

10 x 8 / 2

10 x 8 = 80

80/ 2 = 40

there are 4 of these

40 x 4 = 160

the base is l x w

8 x 8 = base

base = 64

64 + 160 = surface area

surface area = [tex]224mm^{2}[/tex]

the equation for this pyramid would be:

4LH (length x height) + LW( length x width)

or

4lh ( 8 x 10) + lw (8 x 8

Step-by-step explanation:

first we need to find the slope of the line.

the slope is the ratio of "y coordinate change / x coordinate change" when going from one point to the other.

we see here

x changes by -4 (from -4 to -8).

y changes by +3 (from -5 to -2).

so, the slope is +3/-4 = -3/4

there are two main forms for the equation of a line :

the slope-intercept form

y = ax + b

and the point-slope form

y - y1 = a(x - x1)

where "a" is the slope, and (x1, y1) is a point on the line.

we can pick any point, and I would pick (-4, -5).

so we get as point-slope form

y + 5 = -3/4 × (x + 4)

or for the slope intercept form we simplify the point-slope form

y + 5 = -3/4 x + -3/4 × 4 = -3/4 x - 3

y = -3/4 x - 8

Answer:

2714.34 in³ (nearest hundredth)

Step-by-step explanation:

A) Cone and hemisphere

B) volume of a cone = [tex]\dfrac13\pi r^2h[/tex]

volume of a hemisphere = [tex]\dfrac23\pi r^3[/tex]

(where r is the radius and h is the height)

C)

[tex]\implies \textsf{volume of cone}=\dfrac13\pi \times 9^2\times 14=378 \pi[/tex]

[tex]\implies \textsf{volume of hemisphere}=\dfrac23\pi \times 9^3=486 \pi[/tex]

[tex]\implies \textsf{total volume}=378 \pi+486 \pi=864\pi =2714.34 \textsf{ in}^3 \textsf{ (nearest hundredth)}[/tex]

If we look at the rest of the input and output, we also realize that:

         output = input + 5

Thus if the input is 'n' then the output is 'n+5'

Answer:

B

Step-by-step explanation:

each friend received 200 skittles

Answer:

B. 200 Skittles

Step-by-step explanation:

Total skittles = 1248

Skittles eaten = 248

Skittles remaining = 1248 - 248 = 1000

No of friends = 5

No of skittles received by each friend = 1000/5

= 200

Answer:

7 1/2 (7.5)

Step-by-step explanation:

I solved it using conversions and regular math!

3 2/1 = 5 (convert to an improper fraction)

1 1/2 = 3/2 (convert to an improper fraction)

3/2 * 5 = 15/2 (multiply using numerator * numerator (3*5) and denominator  * denominator (2*1))

15/2 = 7 1/2 (convert to a mixed number)

7/12 = 7.5 (convert to a decimal if needed)

Answer:

Step-by-step explanation:

The arithmetic sequence should have a common difference. If the common difference is positive integer then the arithmetic sequence is in increasing order. If the common difference is negative integer then it will be decreasing order.

Eg. 5 , 10 , 15 ,........ Common difference =  +5

    24, 20 , 16 ...... Common difference = -4

Answer:

c = 9

Step-by-step explanation:

Since angle d and 59 are on a right angle (indicated by the small square)

We can equate the sum of these angles to 90:

d+59=90

Now we subtract 59 from both sides:

d+59-59=90-59

d=31

Since angles d,c and 140 are on a straight line we can equate the sum of these 3 to 180:

c+d+140=180

Substitute d with 31 from previous working out:

c+31+140=180

Simplify:

c+171=180

Subtract 171 from both sides:

c+171-171=180-171

Simplify:

c= 9

Answer:

B) Each friend gets 3, there are 4 left over

Step-by-step explanation:

Caden starts with 40 chips.

He takes 12 chips for himself.

40 - 12 = 28

He now has 28 chips left to divide evenly by 8.

28/8 = 3 remainder 4

Check: 3 × 8 = 24, and 24 + 4 = 28

Answer: B) Each friend gets 3, there are 4 left over

[tex]d = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } \\ d = \sqrt{( {2 - ( -1))}^{2} + {(9 - 5)}^{2} } \\ d = \sqrt{ {3}^{2} + {4}^{2} } \\ d = \sqrt{9 + 16} \\ d = \sqrt{25} = 5 \: answer[/tex]

The equivalent radian measure of 540° is calculated to be 3π using the relation between degree and radian.

The value of 180° is equivalent to π radian.

π radian= 180°

as we know that

180° = π radian

1° = π/180 radian

540° = 540* π/180

3π radian

therefore, The equivalent radian measure of 540°  is 3π.

Answer:

9

Step-by-step explanation:

median: The middle number after the numbers have been sorted into ascending or descending order.

Mean: The quotient of the numbers added together then divided by the amount of numbers.

So if 9 were the missing number the median would be 5 because in ascending order it would look like this:

1, 3, 5, 7, 9

and as you can see 5 is in the middle.

The mean would also be 5 because

1+ 3+ 5 + 7 +9 =25

and 25 divided by 5 equals 5

So therefore the missing number must be 9.

(Also it was obvious that they just added 2 to each number)
