Find the surface area of the pyramid.
7 ft
3 ft
The surface area is
square feet.
Answer:
If I understand the definitions correctly,
"surface area" would be the total of all the areas of an object, while "lateral" surface area would exclude the base
so the surface area of a square pyramid
= area of the square base + 4(area of the triangle)
That's my "formua".
In both #1 and #2 you then give dimensions H, W, and L without defining them. If the base is square, how come we have different (W)idths and (L)engths
in #3 Diameter = 8, thus radius = 4
height = 7
Thus slant height of cone = √(4^2 + 7^2) = √65
surface area = πr(r+√(h^2+r^2)
= 4π(4 + √65) = appr 151.58
or surface area = πr^2 + πrs, where s is the slant height
= π(16) + π(4√65) = 151.58

circle WX = xy 2x+16, xw 7x-29 find wx
The value of WX will be; (8y³)/(7y+8).
To find the length of WX, we need to substitute the given values of x and simplify the expression:
WX = xy/(2x+16) - xw/(7x-29)
xy/(2x+16) = xw/(7x-29)
Cross-multiplying, we get:
xy(7x-29) = xw(2x+16)
Expanding both sides;
7x²y - 29xy = 2x²w + 16xw
Rearranging terms and factoring out x;
x(7xy - 2xw) = 29xy - 16xw
Solving for x, we get:
x = (29xy - 16xw)/(7xy - 2xw)
Now we can substitute this value of x into the expression for WX to find its value. use the expression WX = xy/(2x+16):
WX = xy/(2x+16)
WX = y(29xy - 16xw)/[2(7xy - 2xw) + 16]
Simplifying the denominator,
WX = y(29xy - 16xw)/[14xy - 4xw + 16]
Finally, we can substitute the given values of xw and xy to get,
WX = y(29xy - 16xw)/[14xy - 4xw + 16] = (8y³)/(7y+8)
Therefore, WX = (8y³)/(7y+8).

Answer:
y = [tex]\frac{3}{1}[/tex]+1First, we should know what the slope-intercept formula is.
Y = MX + B
Where M is your slope, and B is your y intercept.
Let's do the easiest part first, finding our y-intercept. The y-intercept is where the the line intersects the y-axis. In this case, y = 1, because it intersects at (0, 1).
Now we have:
y = mx + 1
Next, we need to calculate the slope, or rise over run. M is presented as a fraction. The numerator is your rise (how high or low it goes), and the denomenator is your run (how far to the right or left it goes).
If it goes LEFT, the number is negative, if it goes RIGHT it is positive.
Also, pretty points are areas in which the line hits an exact coordinate. Using these points is easiest if you want to find the slope of the line.
We can see that the line hits a pretty point every time it goes one coordinate (box) to the right, and up three boxes. What this means it is rises three 3 points, and runs to the right, 1. This is shown as [tex]\frac{3}{1}[/tex]
So let's add that to the equation!
y = [tex]\frac{3}{1}[/tex]+1

Jim earns $41.25 in 5 hours. Susan earns$30.00 in 4 hours. Pierre’s hourly rate is lessthan Jim’s, but more than Susan’s. What is hishourly rate?
A.$6.50
B.$7.35
C.$7.75
D.$8.25
Answer:
C
Step-by-step explanation:
i it has to be less than gems in more than susans, Jim is making 8.25 per hour, and Susan is making 7.50 per hour.
so the only possible answer would be 7.75
hope this helps!!!
Answer:
C.
Step-by-step explanation:
Jim earns $8.25 every hour
Susan earns $7.5 every hour
So Pierre's hourly rate has to be more than $7.5 but less than $8.25, so therefore Pierre's hourly rate is $7.75 because it is less than $8.25 but more than $7.5

Answer:
AT=48.9
Step-by-step explanation:
Formula:
step 1; Aʟ = P ʙᴀsᴇ × Ap
2
step 2; Aᴛ = Aʟ + Aʙᴀsᴇ
Ap= 7cm
Abase= 6.9cm² P️= a + b+ c
length side️=4cm
AL = (4+4+4) × 7
2
= 12 × 7
2
= 84 ÷2
AL = 42
AT = AL + Abase
= 42 + 6.9
AT = 48.9 cm

Step-by-step explanation:
A farmer is designing a field for his new horse. In order for the field to fit into his farm, the angle θ must be less than 40◦, calculate the size of the angle, with a suitable level of accuracy, and justify if the field will fit or not.
Answer:
The field will not fit
Step-by-step explanation:
To find the angle, we will use cosine rule;
c² = (a² + b² - 2abcosC)
C in this case is θ
Thus;
15² = (8² + 20² - 2(8 × 20)cos θ)
225 = (64 + 400 - 320cos θ)
464 - 225 = 320cos θ
cos θ = 239/320
θ = cos^(-1) 0.7469
θ = 41.68°
Thus angle is not less than 40° as recommended. Thus, the field will not fit.

Find the missing length of the right triangle below.
8 ft
15 ft
Answer:
23 or 19
Step-by-step explanation:
15+8= 23
23-4= 19
i added 15 and 8 because if you were to flatten the triangle it would be next to the base, so i added it. I subtracted 4 because side C doesn't look like it is is about 23 ft. it could be 20 too.
i am not exactly sure. sorry if you get it wrong. I am so sorry if i got it wrong.

Answer:
viii. 2x(1 - 2x)(1 + 2x)(1 + 4x²)
ix. 4xy
Step-by-step explanation:
viii. 2x - 32x⁵
= 2x(1 - 16x⁴)
= 2x(1² - (4x²)²)
= 2x(1 + 4x²)(1 - 4x²) ( a² - b² = (a + b)(a - b))
= 2x(1 + 4x²)(1² - (2x)²)
= 2x(1 + 4x²)(1 - 2x)(1 + 2x)
ix. (x+y)² - (x - y)²
= (x+ y + x - y)( x + y - x + y)
= 2x x 2y
= 4xy

pear is the heaviest, and the strawberry is the lightest
Step-by-step explanation:
This is really simple! Looking at the weight scale, the heavier object always goes lower than the lighter object. Knowing this, we can figure out which is heavier and which is lighter.
10.
Bag A is LIGHTER than Bag B
Bag B is LIGHTER than Bag C
Looking at these we can infer that bag c is heavier than both.
So, Bag A is LIGHTER than Bag C
11. The pear falls lower than the apple, meaning it is heavier. The apple falls lower, meaning is it heavier than the apple. We can infer that the pear is the heaviest, and the strawberry is the lightest
