The table shows the heights of some United States
waterfalls. What is the height of each waterfall?
please help with these problems!! It’s getting really late and they’re due !!
Answer:
b = 9 inches
Step-by-step explanation:
Given that,
The area of triangle LMN = 36 inch²
The height of the triangle, h = 8 inches
We need to find the base of the triangle. The formula for the area of a triangle is given by :
[tex]A=\dfrac{1}{2}bh\\\\b=\dfrac{2A}{h}\\\\b=\dfrac{2\times 36}{8}\\\\b=9\ inches[/tex]
So, the base of the triangle is equal to 9 inches.
When Sophia's mom picks her up from
school, she is late one third of the time. For
the next 15 days, what is the probability
that she will be late at most three days?
Answer:
20.92 %.
Step-by-step explanation:
Add the individual probability of 0, 1, 2, and 3 late days out of 15
P(0 days) = (2/3)15 Notice that I have made P the probability of NOT being late.
P(1 day) = 15(2/3)14(1/3)

Mhnaifa can you please help?
Answer:
1: 9
2: i dont know sorry
3: 21/2
Step-by-step explanation:
1: know that the bottom portion of the triangle is 18 the bottom left is 12 and the top left is 6. Now you could say that its six because they look the same size but we cant be sure, and six isnt an option. i dont know how to solve so we're using process of elimination so bare with me. we alread have 12 and 18 and theyre way bigger, it cant be 11 because it wouldnt be that small. so in my mind its 9.
2: n/A
3: because i said so
Answer:
#1
AQ/QC = AP/PBAQ / 18 = 6 / 12AQ = 18/2AQ = 9Option D
#2
x/ 12 = 10 / 24x = 12*10/24x = 5#3
(x - 8)/5 = 2/42(x - 8) = 52x - 16 = 52x = 21x = 21/2Option B

Find the volume of a rectangular prism with the dimensions:
length: 4 yd
width: 5 ft
height: 11 ft
(keep in mind, that 1 of them is yards and the rest are feet)
Answer:
220
Step-by-step explanation:
V= whl = 5 · 11 · 4 = 220
Find the volume of a rectangular prism with the dimensions:
length: 4 yd
width: 5 ft
height: 11 ft
Answer:-Given:-[tex] \bullet [/tex] Length of a rectangular prism = 4 yards = 4 × 3 = 12 feet.
[tex] \bullet [/tex] Breadth of a rectangular prism = 5 feet.
[tex] \bullet [/tex] Height of a rectangular prism = 11 feet.
To Find:-The volume of a rectangular prism.
Solution:-We know,
Formula of Volume of a rectangular prism is (Length × Breadth × Height) cubic units.
So, Volume = (12 × 5 × 11) cubic feet
Volume = 660 cubic feet
The volume of a rectangular prism is 660 cubic feet. [Answer]OMG PLEASE HELP YOUR BOY OUT I NEED TO GET THIS ONE RIGHT TO PASS THE TEST!!!

Parallelogram FIRE
Given:
[tex]fi = (3x - 5) \: cm[/tex]
[tex]ir = (2y - 7) \: cm[/tex]
[tex]re = (x + 7) \: cm[/tex]
[tex]ef = (y + 3) \: cm[/tex]
a. What is the value of x?
b. How long is FI?
c. What is the value of y?
d. How long is EF?
e. From your answers in b and d, what is the perimeter of parallelogram FIRE?
Answer:
See the solutions below
Step-by-step explanation:
First note that the opposite side of a parallelogram are equal, hence;
For Parallelogram FIRE
fi = re
ef = ir
Given
fi = (3x-5)cm
ir = (2y -7)cm
re = (x+7)cm
ef = (y+3)cm\
a) If fi = re, then;
3x - 5 = x+7
3x - x = 7+5
2x = 12
x = 12/2
x = 6
b) Since FI = 3x - 5
FI = 3(6) - 5
FI = 18 - 5
FI = 13cm
c) Also ef = ir
y+3 = 2y - 7
y - 2y = -7-3
-y = -10
y = 10
d) EF = y+3
EF = 10 +3
EF =13cm
e) Perimeter of the parallelogram = FI + IR + RE + EF
Perimeter of the parallelogram = 13cm + 13 + 13cm + 13cm
Perimeter of the parallelogram = 52cm
4. A cone has a diameter of 6 inches and a height of 6 inches. Find the volume of the cone to the nearest tenth.
Use 3.14 for
a 6.7 in.'
c. 56.5 in.
b. 26.2 in.
d. 91.5 in.
Answer:
56.5 in^2
Step-by-step explanation:
The volume of a cone is π[tex]r^{2}[/tex]h/3. The radius is d/2=6/2=3
V=(3.14 x [tex]3^{2}[/tex] x 6)/3
=(3.14 x 54)/3
=169.56/3
=56.52
Ratio tables what’s the missing ratio
Answer:
16
Step-by-step explanation:
To solve we must first find what the given ratios equal
8/5 = 1.6
40/25 = 1.6
48/30 = 1.6
this means that x/10 = 1.6
To find x... multiply both sides of this equation my 10 to get x alone
x=1.6×10
x=16

What is the measure of ∡U in the figure shown? ∘
Answer:
∠ U = 70°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an exterior angle of the circle , then
∠ U + 50° = 120° ( subtract 50° from both sides )
∠ U = 70°
Solve the system using elimination.
y=-x-3
y=x2-15
Answer:
X=4, y=-7
Step-by-step explanation:
To use elimination method, you want to cancel x or y when adding the equations together. So let’s multiply the first equation by -2
2(y)=2(-x-3)
2y=-2x-6
——————
add above equation 2y=-2x-6
to second equation Y=2x-15
add together. 3y=-21
Y=-7
—————————————-
solve for x by substituting y value (7) into either equation
y=-x-3
-7=-x-3
-4=-x
4=x

What is the area of the following figure?
Answer:
Area = 136
Step-by-step explanation:
Rectangle on the bottom
Length = 16
Width = 7
Area = L * W
Area = 16 * 7
Area = 112
Triangle on Top
Height = 13 - 7 = 6
Length = 16 - 8 = 8
In a right triangle the area = the product of the 2 shortest sides divided by 2
Area = 1/2 * Length * Height
Area = 1/2 * 8 * 6
Area = 1/2 48
Area = 24
Total Area = 112 + 24 = 136
A space shuttle travels at 2.6 x 10,000 feet per second. An hour is 3.6 x 1,000 seconds. This expression can be used to find the number of feet the space shuttle travels in an hour. How many feet does the shuttle travel in an hour?
Answer:
7.22 feet
Step-by-step explanation:
From the question,
s = d/t................. Equation 1
Where s = speed of the space shuttle, d = distance traveled by the shuttle in an hour, t = time taken to travel the distance
make d the subject of the equation,
d = s×t.................... Equation 2
Given: s = 2.6×10000 feet per seconds, t = 1 hour = 3.6×1000 seconds.
Substitute these values into equation 2
d = (2.6×10000)/(3.6×1000)
d = 26000/3600
d = 7.22 feet.
Hence the shuttle travels 7.22 feet in an hour
