And let the missing number be x
We can solve using Algebra
11x - 10 = 34
11x = 34 + 10
11x = 44
x = 44/11
x = 4
For verification:
4(11) - 10 = 34
44 - 10 = 34

A gardener measured the heights of two plants at the end of every week. The function y=3x+8.5 gives the hight of plant a in centimeters at the end of x weeks. The function y= 2.5x+14.5 gives the hight of plant b in centimeters at the end of x weeks
Answer:
12 weeks
Step-by-step explanation:
Step one:
given data
let the heights of the plants be y
and the number of weeks be x
Plant A
y=3x+8.5--------------1
Plant B
y=2.5x+14.5----------2
Required
The number of weeks taken for both plants to have the same height
,equate the two expressions above
3x+8.5=2.5x+14.5
3x-2.5x=14.5-8.5
0.5x= 6
divide both sides by 0.5
x= 6/0.5
x= 12 weeks

Step-by-step explanation:
the volume of cylinder can be 1.5litre and area of its base is 77 . find its height
Answer:
20.07 cm³
Step-by-step explanation:
Volume of Cylinder = 1.54 liters = 1540 cm³.
Area of its base = 77 cm².
πr² = 77
(22/7) * r² = 77
r = 4.94
Now,
Volume of cylinder = πr²h
⇒ 1540 = (22/7) * (4.94)² * h
⇒ h = 20.07 cm³
Given z1 =9+9/3i and z2 = 2+/3i, what is z2-z1?
8+7/3i
-7-8/3i
7+ 10/3i
-7+ 10/3i
Answer:
z2 - z1 = 7/3i
Step-by-step explanation:
Given the following complex number:
z1 = 9+i/3i
z2 = 2+i/3i,
Taking the difference
z2 - z1 = 9+i/3i - (2+i))/3i)
z2-z1 = (9+i-(2+i))/31
z2 - z1 = 9+i -2-i/3i
z2-z1 = 9-2/3i
z2 - z1 = 7/3i
Note that the complex number given was not properly written and the ones used were assumed. Same procedure an be used for other complex numbers that might be given.

Point S is on line segment \overline{RT}
. Given ST=3x-8,ST=3x−8, RT=4x,RT=4x, and RS=4x-7,RS=4x−7, determine the numerical length of \overline{RT}.
RT
.
.
Answer:
RT = 20
Step-by-step explanation:
Point S is on line segment
R------------S------------T
RS + ST = RT
Given
ST=3x-8
RT=4x
RS=4x-7,
Step 1
We find x
4x - 7 + 3x - 8 = 4x
4x + 3x -7 - 8 = 4x
7x - 15 = 4x
7x - 4x = 15
3x = 15
x = 15/3
x = 5
Step 2
We find RT
RT = 4x
x = 5
RT = 4 × 5
RT = 20
The numerical length of RT is 20

41. Write a proof of the theorem that states if an angle of a quadrilateral is supplementary to both of its consecutive angles, the quadrilateral is a parallelogram.
Given: m∠F + m∠G = 180, m∠F + m∠J = 180
Prove: FGHJ is a parallelogram
What statement proves the theorem?
A. By the Angle Addition Postulate m∠F = m∠J and m∠G = m∠H. So, by the definition of a parallelogram, FGHJ is a parallelogram.
B. By the Converse of the Same-Side Interior Angles Postulate, FJ|| GHand FG||JH. So, by the definition of a parallelogram, FGHJ is a parallelogram.
C. By the Polygon Interior Angle-Sum Theorem, m∠F + m∠G + m∠F + m∠J = 360. So, by the definition of a parallelogram, FGHJ is a parallelogram.
D. By the Converse of the Same-Side Interior Angles Postulate, FJ = JH andFG=JH. So, by the definition of a parallelogram, FGHJ is a parallelogram.
Answer:
B.
there's proof that opposite sides are parallel so it must be a parallelogram

Please help! To determine the height of the CN Tower in Toronto, Ontario, Canada a person stands away from the base of the tower and measures the angle of elevation to the top of the tower to be 60°. After moving 118 meters closer to the tower, the angle of elevation to the top of the tower is 70°. A. How tall is the CN tower? B. How far was the person standing from the base of the tower when each angle measurement was taken?
Answer:
A right triangle is formed by the tower, a point 1000m from the tower
Use the tangent. let h = the height of the tower
tan(28.81) = h%2F1000
h = 1000 * tan(28.81)
h = 550 meters

Joey built a skateboarding ramp. The base of the ramp along the ground is 13 feet, and the top of the ramp is 7 feet off the ground. What is the length of the ramp's incline?
Answer:
14.77 feet
Step-by-step explanation:
Using the pythagoras theorem to get the length of the ramp
l² = 13² + 7²
l is the length of the ramp
l² = 169 + 49
l² = 218
l = √218
l = 14.77 feet
Hence the length of the ram is 14.77 feet
A square has a side length of 13 meters. What is the area of the square?
If the dimensions of the square are doubled, what will be the area of the new square?
Answer:
Area of original = 169m^2
Area of new = 676m^2
Step-by-step explanation:
Area of a square = (length of side)^2
13^2 = 13 * 13 = 169
If the dimension is doubled:
(2*13)^2 = 26^2 = 676

According to the Center for disease control, 15% of US adults are estimated to have a chronic kidney disease. A random sample of 150 US adults are selected. What is the probability that exactly 35 have chronic kidney disease
Answer:
[tex]P(X=35) =0.2\%[/tex]
Step-by-step explanation:
From the question we are told that
Sample space n = 150
Sample percentage p = 0.15
Generally people without the disease in the set is give as X
[tex]X= 1-p[/tex]
[tex]X= 0.85[/tex]
35 have kidney disease,
[tex]P(X=35) = C(150,35)*(0.15)^35*(0.85)^115[/tex]
[tex]P(X=35) = 0.0021[/tex]
[tex]P(X=35) =0.2\%[/tex]
