Answer:
A-Third quartile-First quartile
Step-by-step explanation:
The interquartile range is found by taking the third quartile minus the first quartile. It is also found by taking the right side of the box in a box and whisker plot and subtracting the left side of the box in a box and whisker plot
If f(x)=5x-3 find x=2
A.7
B.4
C.-4
D.-5
Answer: A. 7
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
Given Information
f(x) = 5x - 3
x = 2
Substitute the value into the function
f(2) = 5 (2) - 3
f(2) = 10 - 3
f(2) = 7

Shane and Abha earned a team badge that required their team to collect no less than 2000 cans for recycling. Abha collected 178 more cans than Shane did.
Write an inequality to determine the number of cans, S, that Shane could have collected.
What is the solution set of the inequality?
Answer:
Shane=x
Abha=y
x+y>=2000
x-y=178 Which leads to x=178+y ..... #1
hence by substitution in the inequality
178+2y>=2000
2y>=2000-178
2y>=1822
y>=911 ......in #1
x>=178+911
x>=1089
Solutions x>=1089 & y>=911

The volume of this cube is 2.744 cubic meters. What is the value of t?
Answer:
t = 1.4 meters
Step-by-step explanation:
The volume of a cube is given by
V = s^3 where s is the side length
2.744 = t^3
Take the cube root of each side
(2.744) ^ 1/3 = t^3 ^ 1/3
1.4 = t

Answer:
128500
Step-by-step explanation:
This is an arithmetic sequence with a common difference of 3500
The formula for an arithmetic sequence is
an = a1+d(n-1) where a1 is the first term and d is the common difference
an = 48000+ 3500(n-1)
We want n = 24
a24 = 48000+3500(24-1)
= 48000+3500(23)
=48000+80500
=128500

Find the area of triangle ABC.
Answer Options:
A. 18.52 units²
B. 12.16 units²
C. 15.14 units²
D. 31.27 units²
Answer:
Option C, 15.14 units²
Step-by-step explanation:
area of the triangle,
6.82×5.04×sin(61.73)/2
= 15.1365001284..
= 15.14 units² (rounded to the nearest tenth)
The required area of the irregular triangle is 15.14 unit². Option C is correct.
Given that,
A figure of the triangle is shown,
Side AB = a =6.82
Side BC = b = 5.04
Angles, ∠A = 45.03°, ∠B = 61.73°.
The triangle is a geometric shape which includes 3 sides and the sum of the interior angle should not be greater than 180°.
Altitude is perpendicular bisector to the side of the triangle from the opposite vertex of the triangle.
The area of the given triangle can be given as,
Area = 1/2 * a * b sinB
= 1/2 * 6.82 * 5.04 * sin61.73°
= 1/2 * 6.82 * 5.04 * 0.88
= 15.14 unit²
Thus, the required area of the irregular triangle is 15.14 units². Option c is correct.

Lisa kicked a ball against the wall at the indicated angle. What is the measure, in degrees, of <1?
Answer:
68°
Step-by-step explanation:
since the ball is placed or comes from a straight line (which is the wall) it means that when you add all those angles the final answer has to be 180 because angles in a straight line add up to 180°
68°+44°+1=180
112°+1=180
1=180-112
=68°
I hope this helps
The measure of ∠1 is 68 degrees.
We have Lisa who kicked a ball against the wall at the indicated angle.
We have to determine the measure of the angle 1 in degrees.
What is the angle of a straight line ?A straight line has an angle of 180 degrees.
According to question, we have -
∠3 = 68 degrees
∠2 = 44 degrees
Therefore -
∠3 + ∠2 + ∠1 = 180
68 + 44 + ∠1 = 180
112 + ∠1 = 180
∠1 = 180 - 112
∠1 = 68 degrees
Hence, the measure of ∠1 is 68 degrees.

37. for the graph x= -3
please help
Answer: 0
Step-by-step explanation:
Slope of x = -3 is infinite / undefined (there is infinite/no defined change in y for a given change in x). Remember, line x = -3 slopes straight up.
Perpendicular means at a 'right angle to'.
The only kind of line that is perpendicular to a vertical line is a horizontal line, which is like y = 15 or y = 5 or something. The slope of such lines is always zero, because there is no change in line's rise for a given run.

-8a-5=-7a+3 help someone
Answer: a = -8
Step-by-step explanation:
Given
-8a - 5 = -7a + 3
Subtract 3 on both sides
-8a - 5 - 3 = -7a + 3 - 3
-8a - 8 = -7a
Add 8a on both sides
-8a - 8 + 8a = -7a + 8a
a = -8
Hope this helps!! :)
Please let me know if you have any questions
Answer:
a = -8
Step-by-step explanation:
-8a-5=-7a+3 Add 5 to both sides.
- 8a = - 7a + 3 + 5 Combine
-8a = - 7a + 8 Add 7a to both sides
-8a + 7a = 8 Combine
-a = 8 Multiply by - 1
a = - 8
When you get a weird number like this, you should check it.
LHS = -8(-8) - 5
LHS = 64 - 5
LHS = 59
RHS = -(7*-8) + 3
RHS = -(-56) + 3
RHS = 56 + 3
RHS = 59
So a = - 8 must be right.
Triangle GHI, with vertices G(4,-8), H(8,-9), and I(5,-6), is drawn inside a rectangle, as shown below ,What is the area, in square units, of triangle GHI?
Answer:
Hello,
Answer 9/2
Step-by-step explanation:
Let's put some points:
A=(4,-6)
B=(8,-6)
C=(4,-9) (the vertex of the rectangle)
AI=1, IB=3,AB=4
AG=2,GC=1
Area of the triangle AIG=1*2/2=1
Area of the triangle IBH=3*3/2=9/2
Area of the triangle GCH=1*4/2=2
Area of the rectangle=4*3=12
Area of the triangle IGH=12-1-9/2-2=9/2 (unit²)
The area, in square units, of triangle GHI will be 9/2 or 4.5 square units.
What is the area of the triangle?The vertices of the triangle are (x₁, y₁), (x₂, y₂), and (x₃, y₃). Then the area of the triangle will be given as,
Area = 1/2 |[(x₁y₂ + x₂y₃ + x₃y₁) - (y₁x₂ + y₂x₃ + y₃x₁)]|
We have
(x₁, y₁) ⇒ (4, -8)
(x₂, y₂) ⇒ (8, -9)
(x₃, y₃) ⇒ (5, -6)
Then the area will be calculated as,
Area = 1/2[{4 x (-9) + 8 x (-6) + 5 x (-8)} - {- 8 x 8 - 9 x 5 - 6 x 4}]
Area = 1/2 [(-124) – (-133)]
Area = 1/2 x [9]
Area = 9/2 square units
