BRAINLIST!! Look at the inequality graphed on the number line below.
This inequality has
One solution at x = 3
Seven solutions
Three solutions
Eight Solutions
Infinity Solutions
Answer:
I think infinite since it goes on past these numbers.
Step-by-step explanation:
Answer:
Infinity solutions
Step-by-step explanation:
This inequality has infinite solutions because the number line goes from 3 to infinity. this means that there is an uncountable number of solution which means the answer to this question is E.
A billiard ball is struck by a cue. It travels 100 cm before ricocheting off a rail and traveling another 100 cm into a corner pocket. The angle between the path as the ball approaches the rail and the path after it strikes the rail is 45 degrees. How far is the corner pocket from where the cue initially struck the ball?
Answer:
76.53 cm
Step-by-step explanation:
From the question, the triangle formed has 2 sides and an included angle ;
Angle, θ = C = 45°
We use cosine rule :
Taking the side to find as c
a = 100 ; b = 100
From cosine rule :
c = sqrt(a² + b² - 2abCosC)
c = sqrt(100² + 100² - 2(100*100)Cos45
c = sqrt(10000 + 10000 - 20000 * 0.7071067)
c = sqrt(20000 - 14142.135)
c = sqrt(5857.865)
c = 76.536690
c = 76.53 cm
please help i will make brainleist if your correct also pls show answer
Answer:
Step-by-step explanation:
1.
6 * 6 = 36
6 * 6 / 2 = 18
4(18) = 72 (4 triangles)
SA = 36 + 72 = 108 in^2
2.
11 * 4.5 = 49.5
2(49.5) = 99 (2 flaps)
7 * 4.5 = 31.5
2(31.5) = 63 (2 flaps)
11 * 7 = 77
2(77) = 154 (2 flaps)
SA = 99 + 63 + 154 = 316 in^2
3.
25 * 25 = 625
6(625) = 3750 (6 squares)
SA = 3750 ft^2
4.
40 * 60 = 2400
3(2400) = 7200 (3 flaps)
25 * 40 /2 = 500
2(500) = 1000 (2 flaps)
SA = 7200 + 1000 = 8200 cm^2
5.
15 * 9 = 135
3(135) = 405 (3 flaps)
8 * 9 /2 = 36
2(36) = 72 (2 flaps)
SA = 405 + 72 = 477 in^2
6.
9 * 12 = 108
10 * 9 /2 = 45
2(45) = 90 (2 flaps)
12 * 10 /2 = 60
2(60) = 120 (2 flaps)
SA = 108 + 90 + 120 = 318 mm^2
On Sunday morning, 4 1/2 crates of grapes are delivered to thee grocery store. 2/5 of the grapes in each crates are green grapes. How many crates would it take to deliver only the green grapes?
Answer: 1 4/5 crates
Step-by-step explanation:
From the question, we are informed that 4 1/2 crates of grapes are delivered to a grocery store and that 2/5 of the grapes in each crates are green grapes.
The number of crates that it would take to deliver only the green grapes would be:
= 2/5 × 4 1/2
= 2/5 × 9/2
= 9/5
= 1 4/5 crates

what is the measure of angle DEF.
Answer:
DEF = 31.8
Step-by-step explanation:
90 - 58.2 = 31.8
Answer:
Angle DEF = 31.8°
Step-by-step explanation:
The complete angle is a right angle, or 90° angle. To find DEF, you can just do 90° - 58.2° = 31.8°

convert (-5√3,0) into polar form in radians in terms of π over the interval 0≤theta<2π
Answer:
z = 5√3(cos 0 + isin0)
Step-by-step explanation:
Convert (-5√3,0) into polar form in radians in terms of π over the interval 0≤theta<2π
The rectangular form is expressed as z = -5√3 + 0i
z = √(-5√3)² + 0²
z = √(25(3))
z = √75
z = 5√3
Get the argument
theta = tan^-1 0/-5√3
theta = tan^-10
theta = 0 degrees
Hence the polar form is expressed as z = r(cos theta + i sintheta)
z = 5√3(cos 0 + isin0)

Sac had a rope that was 15 feet long. He cut it into three pieces. The first piece was 3.57 feet longer than the second piece. The third piece was 2.97 feet longer than the second piece. How long was the third piece of rope?
Answer:
5.79 feet
Step-by-step explanation:
Let us represent
First piece = x
Second piece = y
Third piece = z
Sac had a rope that was 15 feet long.
x + y + z = 15
He cut it into three pieces.
The first piece was 3.57 feet longer than the second piece.
x = 3.57 + y
The third piece was 2.97 feet longer than the second piece.
z = 2.97 + y
How long was the third piece of rope?
x + y + z = 15
3.57 + y + y + 2.97 + y = 15
3y + 6.54 = 15
3y = 15 - 6.54
3y = 8.46
y = 8.46/3
y = 2.82 feet
Therefore, the length of the third piece z = 2.97 + y
z = 2.82 + 2.97
z = 5.79 feet
x + 3y = 2
-x + 2y = 3

Solve the compound inequality
3t-8/5 and 4-t<-7
Answer: -2.8
Step-by-step explanation:
3t-(8/5) * 4-t < -7
(15t-8)/5 * 4-t < -7
((15t-8)(4-t))/5 < -7
(15t^2)-28t-32< -7
(15t^2)-28t-32-7< 0
(15t^2)-28t-39< 0
Using the quadratic/almighty formula
t= (-b +- ((b^2)-4ac)^(1/2)/2a)
a=15, b=-28, c=-39
t= (-(28) +- (((-28)^2)-4(15)(-39))^(1/2))/2(15))
t= -2.8 or t= 0.9
Since
t<0, then t= -2.8
The mean of 6, 8, x + 2, 10, 2x - 1, and 2 is 9. Find the value of x and also the value of the observation in the data.
Answer:
x = 9
Number of observations = 6
Sum of observations = 54
Step-by-step explanation:
Number of observations, n = 6
Mean = ΣX / n
(6 + 8 + x + 2 + 10 + 2x - 1 + 2) / 6 = 9
(27 + 3x) / 6 = 9
27 + 3x = 6 * 9
27 + 3x = 54
3x = 54 - 27
3x = 27
x = 27 / 3
x = 9

Answer:
The scale Myra should use is one graph unit = 400 km or;
←--→ = 400 km
Step-by-step explanation:
The question relates to the representation of scale drawing
The actual distance between Perth and Sydney = 3294 kilometers
The given coordinates of Perth on the grid = (1.3, 3.4)
The given coordinates of Sydney on the grid = (9.2, 3.3)
The measure of the distance between Perth and Sydney, 'd', is given by using the following formula for finding the distance between two points given their 'x', and 'y' coordinates;
[tex]d = \sqrt{\left (x_{2}-x_{1} \right )^{2}+\left (y_{2}-y_{1} \right )^{2}}[/tex]
Therefore, by substitution, we have;
[tex]d = \sqrt{\left (9.2-1.3 \right )^{2}+\left (3.3-3.4 \right )^{2}} = \sqrt{\left (7.9 \right )^{2}+\left (-0.1 \right )^{2}} = \dfrac{\sqrt{6242} }{10} \approx 7.9[/tex]
d ≈ 7.9 units
Therefore, we have;
7.9 units of the graph = 3294 kilometers
1 unit of the graph ≈ 3294/7.9 km = 416.962025316 km ≈ 416.96 km
Therefore, the scale Myra should use for her map is 1 unit = 400 km.

Mike is mixing paint for his walls. He mixes 1/6 gallon blue paint and 5/9 gallon green paint in a large container. What fraction represents the total amount of paint Mike mixes? The total amount of paint Mike mixes is gallon(s).
Answer:
13/18
Step-by-step explanation:
Mike is mixing paints for his walls
He mixes 1/6 gallons of blue paint
He also mixes 5/9 gallons of green paint
Therefore the total amount of paint mixed can be calculated as follows
1/6 + 5/9
= 39/54
= 13/18
