IONS: Find the value of
85°
45°
Answer:
x = 45, y = 85
Step-by-step explanation:
In this figure we can see a Z-angle, which tells us that x = 45
In a triangle, the sum of the angles is 180 degrees,
so the unknown angle in the triangle is 180 - 45 - 85 = 50
For a straight line, the total angle is 180 degrees,
, so y + x + unknown angle of triangle = 180
since x = 45, and unknown angle of triangle = 50,
y = 180 - 45 - 50 = 85
This can also be seen when you realise that the two parallel lines give an F-angle, which tells us that Y = 85

Joe has a piece of wood that is 8/9 of a foot long. He is going to cut it into 4 equally sized pieces. He is going to sell the 4 smaller pieces of wood for a total of 10 dollars. How large will each of the 4 smaller pieces be? How much is he going to charge for each of the 4 smaller pieces?
Answer:
Step-by-step explanation:
The wood is (8/9) foot long. If cut into 4 pieces, each piece would be (8/9)/4 foot long.
(8/9)/4
((8/9)(1/4)= 8/36 or 2/9 foot long for each piece.
If he sells all 4 pieces for a total of $10, he will charge $10/4) = $2.50 each.

Write the equation in standard form for the circle with center (-5,0) passing through (-5, 3/2)
The equation of the circle in standard form is (x + 5)² + (y)² = 9/4.
How to write the equation of the circle in standard formThe general representation of the equation is:
(x-h)² + (y-k)²= r²
Where (h,k) is the coordinates of the center of the circle and r is the radius. And x and y are the corresponding x and y values of the point the circle passes through
Since we have the coordinate of the center as (-5,0) and the circle passes through (-5, 3/2). Therefore:
h = -5, k = 0, x = -5 and y = 3/2
Let's put these values in the formula.
(x-h)² + (y-k)²= r²
(-5 - (-5) )² + (3/2 - 0)² = r²
(-5 + 5)² + (3/2)²= r²
(0)² + (3/2)²= r²
(3/2)² = r²
r = 3/2
Putting radius, r = 3/2, h = -5 and k = 0 back into the formula wiil give:
(x + 5)² + (y - 0)²= (3/2)²
(x + 5)² + (y)² = 9/4
Therefore,the standard form of the equation of the circle is (x + 5)² + (y)² = 9/4.

To receive an A in a course, John must have an average of 90 or above. If johns first four exam grades are 96,90,87, and 95, what is the minimum grade John can receive on the last exam to get an A in the course?
Answer: 72
Step-by-step explanation:
The average is 90.
To calculate the average, you add the grades and divide by the total amount of them. The number of grades is 5. We need to know what value of x satisfies the following equation:
[tex]90 = \frac{96+90+87+95+x}{5}[/tex]
To solve the equation, we first multiply each side by 5, netting:
450 = 96 + 90 + 87 + 95 + x.
Then we subtract each grade from each side.
450 - 378 = 378 - 378 + x
72 = x

What is an angle?
An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle. Angles created by two rays are located in the plane containing the rays. Angles also were generated when plane cross. These are known as dihedral angles. An angle defined by two intersecting curves is the angle of the rays lying tangent to the respective curves at their point of junction. Angle can also refer to the measurement of an angle or of a rotation. In the case of a geometric angle, the arc is defined by the sides and is centered at the vertex.
Given, angle 1 = 40°
and, angle 2 = angle 3 = x
In a triangle, sum of angles = 180°
or, m∠1 + m∠2 + m∠3 = 180°
or, 2x = 180-40

The probability that the nurse will find the two patients is P = 0.49.
How to find the probability?
We know that the probability that the nurse finds the client on a particular day is 0.7
So, each time that the nurse goes that a home, that probability is the same and is independent of what happened before.
So if the nurse goes to two houses, the probability that she will find the client on the first home is 0.7

Write an equation in slope intercept form to represent the pool filling back up.
*
How long will it take for the pool to fill back up? Explain using words and numbers..
*
We need to find the function in slope-intercept form. We thus need the y-intercept and slope. We know there are 38000 gallons in the pool already, so the y-intercept is 38000. The pool drains 12 per minute, so the slope is -12.
y = mx + b
y = -12x + 38000
To find the time it takes to drain the pool, we need to find x where y = 0, so we set the equation to 0 and solve for x.
0 = -12x + 38000
-38000 = -12x
-38000/-12 = -12x/-12
3167 = x
Now, to fill it back up, the y-intercept is 0. We know the slope is 16, so the equation is:
y = 16x
Finally, we need to find 16x = 38000. This is simple enough.
y = 16x
38000 = 16x
38000/16 = 16x/16

The 96th term of the arithmetic sequence (1, -12, -25,.......) is 1234.
We are provided with the arithmetic sequence mentioned below;
1, -12, -25,...........
We know that, the rule to calculate the nth term in an arithmetic sequence is
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + ( n - 1 ) d equation 1
Here, d is the difference between two consecutive terms in the arithmetic sequence , [tex]a_{1}[/tex] is the first term, n is the number of terms and [tex]a_{n}[/tex] is the nth term.
We have,
n = 96
[tex]a_{1}[/tex] = 1
d = -12 -1 = -13
Now, substitute these values in equation 1 i.e, formula of arithmetic sequence and on substituting we will get
[tex]a_{96}[/tex] = 1 + ( 96 - 1 ) ( -13 )
[tex]a_{96}[/tex] = 1 - (95) (13)
[tex]a_{96}[/tex] = 1 - 1235
[tex]a_{96}[/tex] = 1234

2x- y=-4 x and y intercept
Answer:
y = 2x+4
Step-by-step explanation:
2x - y = -4
We add y on both sides:
2x - y + y = -4 + y
so 2x = -4 + y
We now add 4 on both sides:
2x + 4 = -4 + 4 + y,
so 2x+4 = y,
so y = 2x+4
So intercept for y = 2x+4
