Answer:
She can make :
5 3/5 pies
Algebraic equation =
1 1/4 p = (9 - 2)
Step-by-step explanation:
Clara has 9 pounds of apples. If she saves 2 pounds for applesauce, how many pies, p, can she make?
Total number of pounds of apples = 9 pounds
She saves 2 pounds for apple sauce
The number of pounds of apples left =
9 pounds - 2 pounds
= 7 pounds
She needs 1 1/4 pounds to make one apple pie.
Therefore
1 1/4 pounds = 1 apple pie
7 pounds = p
Cross Multiply
1 1/4 × p = 7 × 1
p = 7 ÷ 1 1/4
p = 7 ÷ 5/4
p = 7 × 4/5
p = 28/5
p = 5 3/5 pies
An Algebraic equation for this situation is:
1 1/4 p = (9 - 2)
Where p = Number of pies

True or False: The area of a circle with diameter d = 2r = 10 is greater than the area of an ellipse with major axis 2a = 10. Explain your answer. Note: the area of an ellipse is calculated with the formula = (with ‘a’ the length of the semi-major axis and ‘b’ the length of the semiminor axis). Explain why as well.
Answer:
True
Step-by-step explanation:
So the radius would be 5 (as you times it by 2 to get 10)
Therefore
2a=10 is the same as what the circle with diameter d=2r=10

From the given figure , we can see that there are two angles whose measures are x and 2x - 30°. If we notice they are the angles on the same segment . ( Draw a line through the end points of the two lines , and they will be on the same chord) . And we know that angles of the same segment are equal . Therefore ,

a.
y = 2 x
b.
y = 2 x minus 3
c.
y = 2
d.
y = 2 x + 10
Please select the best answer from the choices provided
A
B
C
D
Answer:
c). y = 2
Step-by-step explanation:
We can check a line by inputting the x and y from (x, y) into the equation.
For a. y = 2x we get
2 = 2*10 and 2 = 2*(-3), both of those are false
For b. y = 2x - 3 we get
2 = 2*10 - 3 and 2 = 2*(-3) + 10, both of those are false again
For c. y = 2 we get
2 = 2 and 2 = 2, both of those are true, so this is the right answer.
For d. y = 2x + 10 we get
2 = 2*10 + 10 and 2 = 2*(-3) + 10, both of those are false
Alternatively, we can solve the equation y = ax + b (this gives a single answer for any two points with different x's).
y = ax + b
We input (x, y) as (10, 2) and (-3, 2)
2 = a*10 + b = 10a + b
2 = a*(-3) + b = b - 3a
so we have
10a + b = b - 3a
13a = b - b
13a = 0
a = 0
Now we ca use a = 0 to solve either of the equations above:
2 = 10a + b
2 = 10*0 + b
2 = b
so with a=0 and b=2 we get the answer
y = 0*x + 2
y = 2
Which brings us to answer c. again.
An angle measure 8 less than the measure of its supplementary angle what is the measure of each angle
Answer:
94° and 86°
Step-by-step explanation:
'x-8' = smaller angle
'x' = larger angle
x - 8 + x = 180
2x = 188
x = 94
94 - 8 = 86

Linear Function
Step-by-step explanation:
Formula: y = 4x - 2
Plug in the values of x or y for each ordered pair:
y = 4(0) - 2
y = 0 - 2
y = -2
(0, -2)
y = 4(-2) - 2
y = -8 - 2
y = -10
(-2, -10)
14 = 4x - 2
12 = 4x

-14 = 4x - 2
-12 = 4x
-3 = x
(-3, -14)
What type of function is it?
Linear function
Why is it a linear function?
Refer back to the original formula given: y = 4x - 2. This is in slope-intercept form, or y = mx + b. This specific format informs graphers the line will be straight, or linear. You can also graph all of the ordered pairs to obtain a visual of a straight line, proving this function to be linear.

Step-by-step explanation:
What is the sum of the interior angles of the polygon pictured below?
The shape has 9 sides.
Sum of interior angles = (n-2) x 180, where n is the number of sides.
Sum of interior angles = (9-2) x 180 = 7 x 180 = 1,260 degrees.
Answer:
Solution :-We have
Side of polygon = 9
So,
By using the formula
(n - 2) × 180
(9 - 2) × 180
7 × 180

The work of a student to solve a set of equations is shown below:
Equation 1: x + 2y = 10
Equation 2: 2x + 5y = 15
Step 1: −2(x + 2y) = −2(10)
2x + 5y = 15
Step 2: −2x − 4y = −10
2x + 5y = 15
Step 3: 1y = 5
Step 4: x + 2(1) = 10
Step 5: x = 8
In which step did the student first make an error?
Step 1
Step 2
Step 3
Step 4
Answer:
Step 2 has error and step 4 has error.
Step-by-step explanation:
Here we can see that elimination method is applied to solve the system of equations for which -2 is multiplied both sides of equation first
-2(x+2y)=-2(10 which is correct
but in step 2
left side is -2x-4y and the right side is -10 which has to be -20 which makes this step wrong and this is the error made by student.
in Step 4 also ,value of the y has to be 5 but student plugged y =1 which is also error by student.
Correct solution is
-2x-4y= -20
2x+ 5y= 15
on adding ,we get
y = -5
plugging y =5 in equation x+2y= 10 ,we get x+2(-5) =10 ,we get x = 20
therefore (20,-5) is the solution

Answer:
Angle 6 = 46°
Angle 7 = 134°
Angle 8 = 77°
Step-by-step explanation:
Angle 6 = 180 - 134 (Due to the angles on a straight line add up to 180 property)
Angle 6 = 46°
Angle 7 = 180 - 46
Angle 7 = 134°
360 = 56+148+(2 x Angle 8)
2 x Angle 8 = 360-204
2 x Angle 8 = 156
Angle 8 = 78°

If the angle of a sector measures 45° what fraction of the circle is the sector
The fraction of the circle measured by a sector which subtends an angle; 45° is; 1/8 (one-eighth).
It has been established from circle geometry that the angle subtended at a point is 360°.
On this note, the algebraic sum of angles in a circle is; 360°.In essence, a sector which measures 45° is only 1/8 of the circle.
