The answer is in the pic below
Step-by-step explanation:
Answer:
x = 4.3 (repeating 3) in Decimal Form
x = 13/3 in Exact Form
x = 4 1/3 in Mixed Number Form
Step-by-step explanation:
180=16x - 5 + 5x +4 + 90
180 = 21x -5 + 4 + 90 (combine like terms)
180 = 21x + 89
180 = 21x + 89 (subtract 89 on both sides)
-89 - 89
91 = 21x (divide 21 by both sides)
91/21 = 21x/21
4.3 (repeating 3) = x

an=81,d=-3,n=18 solve the question by using formula an=a+(n-1)d
Answers
Step-by-step explanation:
An = A + (n - 1)d
We have An = 81, d = -3 and n = 18.
Hence A = An - (n - 1)d = 81 - (17)(-3) = 132.
81= a+-3{18-1]
Solve the brackets
81= a-3[17]
81= a-51
Move 51 to the other side as a positive number
81+51 is 139
Therefore, a is equal to 139

Answer: 31.18
Step-by-step explanation:
The problem is focused on mainly the right triangle made up of points M, Q, and R. This problem can be solved with the base formula, b = a · tan(β) where a = the length of line MR, β = m∠MQR, and b is the unknown length of RQ.
Given:
RQ = 18 · tan(60°)
Point M is the midpoint of line PM and line MR. Since MP is equal to 18, MR has to be 18 as well. This means that the value of a is 18.
The vertex of ∠MQR is Q, which is 60°.
Step 1: Find the tangent of 60°
The tangent of 60° is √3
Step 2: Solve
RQ = 18 · √3
18 · √3 = 31.18
RQ is equal to 31.18

Answers
Answer: If a team uses 75 water bottles when the temperature is 60 degrees, ( 75 - 15 = 60 )

x = 7/10
(substitute x = 7/10 in the ‘x’ spot in either of the two equations)

The sector of a circle is shown below. It has a radius of 10 centimeters and a central
angle of 51 degrees. Find to the nearest tenth in both cases:
(a) the length of AB in centimeters(b) the area of the sector in square centimeters
Answers
Answer:
1. 9.8 cm
2. 44.5 cm^2
Step-by-step explanation:
1. To find the length of arc AB, we use the formula for the length of an arc
Mathematically, that will be;
theta/360 * 2 * pi * r
theta is the central angle which is 51
r is the radius which is 10 cm
So we have
51/360 * 2 * 22/7 * 10 = 8.9 cm
2. The area of the sector
we use the formula for the area of a sector here,
That is;
theta/360 * pi * r^2
51/360 * 22/7 * 10 * 10
= 44.5 cm^2
A cyclist rode for 3.5 hours and completed a distance of 60.9 miles. If she kept the same average speed for each hour, how far did she ride in 1 hour? Part A Estimate the quotient. Include an equation to show your work. Explain
Answers
Answer:
17.4 milesStep-by-step explanation:
Step one:
given data
time takent= 3.5hours
distance = 60.9miles
the average speed is given as
Average speed= distance/time
Average speed= 60.9/3.5
Average speed= 17.4mph
Step two:
we are told that the speed was actually maintained, so we used the previous value obatained for the following computation
For a time taken as 1 hour, the distance will be
distance= average speed * time
distance= 17.4*1
distance= 17.4 miles

Answer:
∠ CAD = 83°
Step-by-step explanation:
In a parallelogram. opposite angles are congruent.
∠ CAB = ∠ ACD = 57° ( Alternate angles )
The sum of the 4 interior angles = 360°
and
∠ ABC + ∠ CDA = 40° + 40° = 80°
Thus
∠ BCD + ∠ CAD = 360° - 80° = 280°, then
∠ DAB = 140° ( congruent opposite angles )
Thus
∠ CAD = 140° - ∠ CAB = 140° - 57° = 83°

Composite functions are functions that are gotten from combining multiple functions.
The value of the composite function (f o g)(x) is 3x^2 -3.
The functions are given as:
[tex]f(x) = x + 4[/tex]
[tex]g(x) = 3x^2 - 7[/tex]
To calculate the composite function (f o g)(x), we make use of:
[tex](f\ o\ g)(x) = f(g(x))[/tex]
We have:
[tex]f(x) = x + 4[/tex]
Substitute g(x) for x
[tex]f(g(x)) = g(x) + 4[/tex]
Substitute [tex]g(x) = 3x^2 - 7[/tex]
[tex]f(g(x)) = 3x^2 - 7 + 4[/tex]
[tex]f(g(x)) = 3x^2 -3[/tex]
Recall that:
[tex](f\ o\ g)(x) = f(g(x))[/tex]
So, we have:
[tex](f\ o\ g)(x) = 3x^2 -3[/tex]
Hence, the value of the composite function (f o g)(x) is 3x^2 -3.

Chase lives 1 and one half blocks west of Ellie. They draw a number line to model this situation. Because Ellie lives 1 and three fifths blocks east of school, they give her house the coordinate 1 and three fifths . Chase incorrectly claims that the coordinate of his house is 3 and one tenth . What is the correct coordinate of Chase's house? What is Chase's likely error?
Answers
Answer:
1/10
Step-by-step explanation:
A number line is a line which contains numbers marked at intervals (usually regular intervals). Points to the right of the origin are positive numbers while those to the left are negative numbers.
The school is used as the origin. Ellie house is 1 and three fifths blocks east (to the right) of the school. This means that it is + 1 and three fifths (+8/5).
Chase house is 1 and one half blocks (3/2) west of Ellie. Since it is west then it is to the left. Hence the coordinate of chase house = 8/5 - 3/2 = 1/10
Hence the coordinate of chase house is 1/10(one tenths).
The error may be as a result of thinking chase house is to the east of Ellie, hence adding to get 3 and one tenth.
