Ali earns 150$ in 4 hours at this rate how many hours will it take him to earn 525
Answer:
14 hours
Step-by-step explanation:
Find the rate of what he earns per hour.
150 ÷ 4 = $37.50
Divide $525 with the rate:
525 ÷ 37.50 = 14
It would take him 14 hours
Calculate the shaded area
Answer:
116 cm²
Step-by-step explanation:
area shaded = total area - area not shaded
πr² is the area of a circle
total area = πr² = π*(6.5cm)² = 132.732289614 cm²
area not shaded = πr² (note the radius is 2.3cm for the non-shaded portion) = π*(2.3cm)² = 16.6190251375 cm²
area shaded = total area - area not shaded = 132.732289614 cm² - 16.6190251375 cm² = 116.113264476 cm² ≈ 116 cm²

Solve step by step -18=2(-q+4)
Answer:
q=13
Step-by-step explanation:
First, you can multiply to distribute 2 over -9 and 4.
-18=2(-q+4)
-18=-2q+8
Then, you can subtract 8 from both sides.
-18=-2q+8
-26=-2q
Finally, you can divide -2 on both sides.
13=q
Now, you can check by plugging in 13 for the value of q in the original equation.
-18=2(-(13)+4)
-18=2(-13+4)
-18=2(-9)
-18=-18
Hope this helps you! :)
A circle is drawn on the (x,y) coordinate plane so that the center is at the point (-3,0). If the radius of the circle is 5, then each of the following points lie on the circle's circumference EXCEPT:
Answer:
2,5
Step-by-step explanation:
since radius is 5
each point lies on the circumference that has 5 or -5 in its y coordinates must have -3 in its x coordinate because -3 is the center
then option number 1 is incorrect
second option is correct , -3 + ( -5 ) = -8
third option is correct, -3 + 5 = 2
fourth is correct, -3 is the center and 5 steps on y axis
fifth is the same as fourth but opposite direction
so the first one is the exception

3m+8=15, is it quadratic or not quadratic? If your answer is not quadratic, explain.
3m + 8 = 15 is not a quadratic equation. quadratic equation must have the power of 2 in the quadratic term.
Answer:
Definitely not.
Step-by-step explanation:
3m+8=15
A quadratic equation needs to consist of these values:
x^2+x+y
In this case x can be followed by any coefficient but needs to end with a variable to the power of 2. The second part of this question needs to have that variable- but to no power. Finally, the third part is just a regular integer. We can tell 3m+8=15 is not a quadratic because while it has a variable and integer, it does not have a variable to the power of two.

83, acute
Step-by-step explanation:
49 + 48 + x = 180
97 + x = 180
x = 83
All angles are smaller than 90 so they all are acute and that makes this trinagle an acute triangle. So cute! :)

The solutions of the given linear equations are: x = 7, - 13; x = 6, - 7; x = 5, - 9, respectively.
What is a linear equation?A linear equation is an equation that has on or multiple variables with the highest power of the variable is 1.
Given equations are:
1. |3x + 9| = 30
⇒ ( |3x + 9| )² = (30)²
⇒ 9x² + 54x + 81 = 900
⇒ 9x² + 54x + 81 - 900 = 0
⇒ 9x² + 54x - 819 = 0
⇒ 9(x² + 6x - 91) = 0
⇒ (x² + 6x - 91) = 0
⇒ (x + 13)(x - 7) = 0
⇒ x = 7, - 13
2. |2x+1| = - 13
⇒ (|2x+1|)² = (- 13)²
⇒ 4x² + 4x + 1 = 169
⇒ 4x² + 4x - 168 = 0
⇒ 4(x² + x - 42)= 0
⇒ (x² + x - 42)= 0
⇒(x - 6)(x + 7) = 0
⇒ x = 6, - 7
3. |x + 2| + 4 = 11
⇒ |x + 2| = 7

⇒ x² + 4x + 4 = 49
⇒ x² + 4x - 45 = 0
⇒ (x - 5)(x + 9) = 0

Which equations show the total volume of the boxes Marcus shipped? Select the three equations that apply.
Using the volume of a rectangular prism, it is found that Marcus shipped 2040 in³ of the boxes.
What is the volume of a rectangular prism?The volume of a rectangular prism of lenght l, width w and height h is given by:
V = lwh.
Prism 1 has dimensions of h = 10, l = 20, w = 7, hence it's volume in cubic inches is given by:
V1 = 20 x 10 x 7 = 1400 in³.
Prism 2 has dimensions of h = 4, l = 20, w = 4, hence it's volume in cubic inches is given by:
V2 = 20 x 4 x 4 = 320 in³.
Marcus shipped 1 of the larger boxes and 2 of the smaller boxes, hence the total volume is of:

100pts...!Determine the image of the point (7, 3) under a rotation of 90° about the origin.
(-7, 3)
(-3, -7)
(-3, 7)
(3, 7)
Answer:
(-3, 7)
Step-by-step explanation:
The rotation of an object turns the object around a fixed point called the center of rotation.
Positive rotations are counterclockwise.
Negative rotations are clockwise.
Therefore, rotation of 90° about the origin means a 90° rotation counterclockwise with (0, 0) as the center of rotation.
The rule for rotation of 90° about the origin is:
(x, y) → (-y, x)
Therefore (7, 3) → (-3, 7)
The rule of 90° rotation about the origin is
(x,y)—»(-y,x)Here given point is

Step-by-step explanation:
In right-angled triangle, the difference between two of the angles is 20 degrees. a) Work out the Size of the angles in the triangle. b) How many solutions are there to A?
Answer:
The sum of interior angles of a triangle is 180°
In a right triangle, one of the three angles is 90°. Therefore, the sum of the other two angles is 90°.
Let a = one unknown angle
Let b = the other unknown angle
As the sum of the angles is 90°:
⇒ a + b = 90°
As the difference between the two angles is 20°:
⇒ a - b = 20°
Rewriting the first equation to make a the subject:
⇒ a = 90° - b
Substituting this into the second equation and solving for b:
⇒ 90° - b - b = 20°
⇒ 90° -2b = 20°
⇒ 70° = 2b
⇒ b = 35°
Substituting found value for b into a = 90° - b and solving for a:
⇒ a = 90° - 35°
⇒ a = 55°
Therefore, the two unknown angles are 35° and 55°
Suppose the sample space for a continuous random variable is 0 to 400. If
the area under the density curve for the variable from 0 to 72 is 0.18, what is
the area under the density curve from 72 to 400?
A. 0.92
O B. 0.18
O C. 0.82
D. 0.982
Answer:
P(72 ≤ x ≤ 400) = 0.82. Correct: C.
Explanation:
Probability Distribution
In any probability distribution, the total probability of the sample space must be 1.
Since the sample space is given as a random variable x that takes values from 0 to 400, then:
P(0 ≤ x ≤ 400) = 1
For any value of x:
If the sample space is divided into two parts like:
P(0 ≤ x ≤ 72) and P(72 ≤ x ≤ 400), then the combined probability must be 1:
P(0 ≤ x ≤ 72) + P(72 ≤ x ≤ 400) = 1
Or, equivalently:
P(72 ≤ x ≤ 400) = 1 - P(0 ≤ x ≤ 72)
P(72 ≤ x ≤ 400) = 1 - 0.18
P(72 ≤ x ≤ 400) = 0.82
A. The value 0.92 is not correct since does not match with the value 0.82.
B. The value 0.18 is not correct since does not match with the value 0.82.
C. This is the correct value. Correct Choice
