I need help will u determine the surface area of this pyramid
50 points
Answer:
[tex]224mm^{2}[/tex]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

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]

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

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

1 1/2 x 3 2/1 if u get it I give u 30 bucks
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)

i have no clue what is even happening in this qs! help
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)

What is the equivalent radian measure of 540°? One-third radians StartFraction 3 Over pi EndFraction radians StartFraction pi Over 3 EndFraction radians 3 pi radians.
The equivalent radian measure of 540° is calculated to be 3π using the relation between degree and radian.
what is the relation between radian and degree?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.

What must an arithmetic sequence have? Question 2 options: common difference common ratio difference of two squares polynomials
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
What is an equation of the line that passes through the points (-4,-5) and
(-8, -2)?
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

Caden has 40 chips that he wants to share evenly amongst 8 friends. Caden
takes 12 chips for himself before he splits the chips. How many chips does
each friend get? Are there any chips left over?
A) Each friend gets 3, there are 3 left over
B) Each friend gets 3, there are 4 left over
C) Each friend gets 3, there are 2 left over
D) Each friend gets 3, there are 5 left over
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
