Answer:
The answer is b
Step-by-step explanation:
I know this because a coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression and since 9 is being multiplied by x that would mean 9 is a coefficient in this expression.

7. Diana took 2 hours to cycle from town X to town Y. Her average speed was 10 kilometers per
hour.
a) Find the distance between the two towns. (2 marks)
b) If her average speed was increased by 2 kilometers per hour, how much time would she take
for the journey? (2 marks)
Answers
Answer:
a.) 20 kilometers
b.)1.67 hours
Step-by-step explanation:
a.) formula= speed =distance/time
Speed= 10km/hr
Distance=unknown
Time=2hrs
Therefore from formula, distance=speed x time
10 x 2
20 kilometers
b.) If average speed is increased by 2km/hr then
total speed= 2+10=12km/hr
Distance remains constant therefore distance= 20km
Therefore time =distance/speed
20/12
= 1.67 hours
HLPPPPPPPP MEEEEEEEEEEEEE PLZZZZZZZZZZZZ if d is the circumference of abc what is the measure of aex
Answers
Answer:
∠AEX = 70°
Step-by-step explanation:
From the diagram
AX ≅ BX
BY ≅ CY
AZ ≅ CZ
∠XAE = 20°
A circumcenter has equal distant from vertices of the triangle since radii of circles are congruent.
For the given figure, the midpoints is at Z, X, Y
And the perpendiculars also occur at Z, X, Y
∠Z = 90°
∠X = 90°
∠Y = 90°
∠XAE ∠AXE +∠AEX= 180° (sum of angles in a triangle)
∠AXE = ∠X = 90°
20° + 90° +∠AEX= 180°
110° +∠AEX= 180°
∠AEX = 180°-110°
∠AEX = 70°

10. tan(30) = l / 6√3
l = tan(30) x 6√3
l = 6
cos(30) = 6√3 / y
y = 6√3/cos(30)
y = 12
11. tan(30) = c/30
c = 30 x tan(30)
c = 10√3
cos(30) = 27/w
w = 27/cos(30)
w = 18√3

Answer:
10. (l, y) = (6, 12)
11. (c, w) = (9√3, 18√3)
12. (x, y) = (12√3, 24√3)
Step-by-step explanation:
Side ratios, shortest to longest, in a 30°-60°-90° triangle are ...
1 : √3 : 2

10. l : 6√3 : y = 1 : √3 : 2
multiply by 6

A new restaurant opens, and on the first night has 100 guests. Each night after that, the number of guests grows by 20 people. What type of sequence does this scenario represent, and why? If the pattern of the sequence continues, how many guests will the restaurant have on its 14th night?
Answers
What type of sequence does this scenario represent, and why?
✔ arithmetic; the sequence has a common difference
If the pattern of the sequence continues, how many guests will the restaurant have on its 14th night?
✔ 360
This example doesn't accurately depict arithmetic because the succession has a common difference. The restaurant will host 360 customers on its fourteenth night if the pattern of the series holds.
Calculate arithmetic sequence nth term?Arithmetic sequences always add or subtract the same amount to go from one term to the next. Finding the difference between any AP phrase and its predecessor will reveal the common difference, indicated by the letter "d."
An arithmetic sequence's nth term is determined by, Formula an = a1 + (n - 1)d. The common difference, or d, is the difference between any two consecutive terms in an arithmetic series; it can be calculated by deducting any pair of terms starting with a and an+1.
an = 100 + (14 - 1)20.
an = 360
The restaurant will host 360 customers on its fourteenth night if the pattern of the series holds.

IF Quadrilateral ABCD was rotated 90 degrees clockwise about point C, what would be the coordinates of B’?
A) (1, 1)
B) (2, 4)
C) (4, 2)
Answers
Answer:
X1,Y1
Step-by-step explanation:
If the Quadrilateral was rotated 90 degrees clockwise around point C, C would still be on the same X line that it is currently on but, point B would also rotate down to that same horizontal line. Between point C and point B there is a space of 3 units, so if that rotated 90 degrees clockwise it would be 3 units to the right of the current position of point C.

the measure of angle 1 is twice the measure of angle 2, and angle 1 and angle 2 are linear pair. Find the measure of angle 1.
Answers
Answer:
m<1=120
Step-by-step explanation:
A linear pair adds up to 180 degrees.
So <1+<2=180
Let <2=X, that would make <1=2X because <1 is 2 times more.
So substitute that into the equation.
2x+x=180.
Combine like terms and get 3x=180
Divide both sides by 3 and get x=60.
Substitute that into <1 and get <1=120

find the value of x when m<2= 8x
Answers
Answer:
x = 10
Step-by-step explanation:
The base angles of an isosceles triangle measure the same
The three angles of the triangle and 50 , 50 and <2
They sum to 180 degrees
50 +50 + 8x = 180
Combine like terms
100+8x = 180
Subtract 100 from each side
100-100 +8x = 180 - 100
8x= 80
Divide by 8
8x/8 = 80/8
x = 10
Answer:
x =10
Step-by-step explanation:
this is isosceles Δ so it has base ∠ that are =
sum of angles in Δ is 180 so 180 -50-50 = 80
m<2= 80
80= 8x
x =10
The maximum height of a vehicle that can pass under a bridge is 12 feet 5 inches. A truck measures 162 inches in height. Which best explains whether or not the truck can pass safely under the bridge?
Answers
Answer:
The truck can not safely pass under the bridge
Step-by-step explanation:
The maximum height in inches is 149in.
12 feet times 12 inches = 144 in
144 +5 = 149in
If the truck is 162 inches than it would not be safe for it to pass under the bridge.

solve for x.
12x - 8 = 8x - 20
Answers
Answer:
x= -3
Step-by-step explanation:
12x-8x = -20+8
4x = -12
x= -12/4
x = -3
Steps:
Step 1: Subtract 8x from both sides.
12x−8−8x=8x−20−8x
4x−8=−20
Step 2: Add 8 to both sides.
4x−8+8=−20+8
4x=−12
Step 3: Divide both sides by 4.
4x/4 = −12/4
Answer: x=−3

We are trying to isolate x so we can move all the constant to one side.

-1.1x>-7.7
Lastly, we need to divide both sides by -1.1.
-1.1x>-7.7/-1.1
Note that if you multiply or divide both sides of an inequality by a negative, then you need to flip the sign.
