how much fat is in a mixture created with x pints of 8% butterfat and y pints of 15% butterfat
Answer:
Total mixture = (8x + 15y) / 100
Step-by-step explanation:
Butterfat x:
= 8% of x
= 8/100 * x
= (8 * x) / 100
= 8x / 100
Butterfat y:
= 15% of y
= 15/100 * y
= (15 * y) / 100
= 15y / 100
Total mixture = butterfat x + butterfat y
= 8x / 100 + 15y / 100
= (8x + 15y) / 100
Total mixture = (8x + 15y) / 100
If mZGEF is thirteen less than five times
mZDEG and mZDEF = 149°, find mZGEF.
F
D
G
Answer:
Step-by-step explanation:
Given :
From the diagram,
m∠GEF is 13 less than 5 times m∠DEG and ∠DEF = 149°,.
To Find :
the value of m∠GEF..
Solution :
As per given data,
m∠GEF = 5m∠DEG - 13° ...(i)
∠DEF = 149° ⇒ m∠GEF + m∠DEG = 149° ..(ii)
Substituting value of m∠GEF in (ii),
We get,
(5m∠DEG - 13°) + m∠DEG = 149°
6m∠DEG - 13° = 149°
6m∠DEG = 149° + 13° = 162°
m∠DEG = ° = 27°
Substituting value of m∠DEG in (i),
We get,
m∠GEF = 5(27°) - 13°
m∠GEF = 135° - 13°= 122°

Determine the value of x.
A) 160°
B) 78°
C) 240°
D) 80°
Answer:
D) 80°
Step-by-step explanation:
(n - 2)180 = 4(180) = 720
78 + 134 + 136 + 132 + 2x + x = 720
3x + 480 = 720
3x = 240
x = 80
Answer:
The answer is D:80 degrees.

Find the measure of b.
A. 110
B. 55
C. 75
D. 125
Answer:
B
Step-by-step explanation:
The central angle is twice the angle on the circumference, subtended on the same arc, then
a = 0.5 × 110° = 55° → B
the required measure of angle b inscribed in the circle is 125.
A figure is shown, in which a measure of b is to be determined.
The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²,
where h, k is the coordinate of the circle's center on a coordinate plane, and r is the circle's radius.
Since, As shown in the figure
the angle subtended by an arc on center is twice the angle subtended by the same are to the point of circumference corresponding point on the circle.
Angle b ,
2b = 360 - 110
2b = 250
b = 250/2
b = 125
Thus, the required measure of angle b inscribed in the circle is 125.

Reflect triangle ABC across the line x = 2. Then the reflect (image) A' B' C' across the line x = -3.
Answer:
1. ΔA'B'C' = A' = (1, 1), B'(-1, 1), and C'(1, 4)
2. ΔA''B''C'' = A''(-7 1), B''(-15 1), and C''(-7, 4)
Step-by-step explanation:
1. The coordinates of the triangle ΔABC are; A(3, 1), B(5, 1), and C(3, 4)
The reflection of a line across the line x = 2, is given as follows
The distance between the x-coordinate of the preimage and the line of reflection which is parallel to the x-axis = The distance of the x-coordinate of the preimage from the line of reflection but opposite in sign
The distance from A(3, 1) from x = 2 is 3 - 2 = 1, therefore, the x-coordinate of the image, A' = 2 - 1 = 1, therefore, we have;
The coordinate of A' = (1, 1)
Similarly, we have; B(5, 1) (reflection across x = 2) → B'(-1, 1)
C(3, 4) (reflection across x = 2) → C'(1, 4)
Therefore when we reflect ABC across the line x = 2, we get ΔA'B'C', with A' = (1, 1), B'(-1, 1), and C'(1, 4)
2. Reflection of A'B'C' across the line x = -3, gives;
A'(1, 1) (reflection across x = -3) → A''(-7 1)
B'(-1, 1) (reflection across x = -3) → B''(-15 1)
C'(1, 4) (reflection across x = -3) → C''(-7, 4)
The coordinates of the reflection of ΔA'B'C' across the line x = -3 is ΔA''B''C'' = A''(-7 1), B''(-15 1), and C''(-7, 4)

Which of the following verifies that ST¯¯¯¯¯∥QR¯¯¯¯¯?
Answer:
Step-by-step explanation:
From the picture attached,
If ΔPRQ ~ ΔPTS,
By the property of similar triangles,
Corresponding sides of the similar triangles are proportional.
[tex]\frac{PR}{PT}= \frac{PQ}{PS}[/tex]
[tex]\frac{7.5+4.5}{4.5}= \frac{20}{7.5}[/tex]
[tex]\frac{12}{4.5}=\frac{20}{7.5}[/tex]
[tex]\frac{120}{45}= \frac{200}{75}[/tex]
[tex]\frac{8}{3}=\frac{8}{3}[/tex]
By the converse of similar triangles,
If two triangles ΔPRQ and ΔPTS are similar, sides ST and QR will be parallel.
Given the algebraic representation of a linear transformation (x,y) (3x-4, 1/5y-2),what trasformations are occuring
Answer:
We can define the algebraic transformations used here as:
Horizontal translation.
For a general point (x, y), a horizontal translation of N units is written as:
(x + N, y)
if N < 0, the translation is to the left
if N > 0, the translation is to the right.
Vertical translation:
For a general point (x, y), a vertical translation of N units is written as:
(x , y + N)
If N < 0, the translation is downwards
if N > 0, the translation is upwards.
Vertical dilation:
For a point (x, y), a vertical dilation of scale factor k is given by:
(y, k*y)
Horizontal dilation:
A dilation of scale factor k is written as:
(x/k, y)
Here we go from:
(x, y) to (3x - 4, (1/5)*y - 2)
So we have:
An horizontal dilation of scale factor 1/3 followed of a horizontal translation of 4 units.
And a vertical dilation of scale factor (1/5) followed by a translation downwards of 2 units.
Ugh I’m kinda stuck someone can help me ?
Answer:
To graph this line, move one of the points to positive three on the horizontal (side to side) line and negative six on the vertical (up and down) line. To get a slope of negative 1/2 you move down one point and right two points, and you continue until you reach the edge of the graph. Then you do the opposite on the way up (up one and left two).
Hope this helps!
Answer: Plot the two points (3,-6) and (1, -5). Draw a straight line through those points.
See the graph below.
=============================================
Explanation:
Plot the point (3, -6)
The slope -1/2 means the rise is -1 and the run is 2
rise = -1run = 2If we moved to the right, then we'd drop down 1 and move to the right 2. That would move us from (3,-6) to (5,-7)
We can go in reverse of this. So instead of "move down 1", we move up 1. We're going left instead of right.
-----------
So we start at (3,-6) and move up 1 and to the left 2 to arrive at (1,-5)
Two points on this line are (1, -5) and (3, -6)
Once we have two points, we have enough to graph the line.
See the graph below.

For the functions f(x) = 2x − 6 and g(x) = 5x + 1, which composition produces the greatest output?
Answer:
g(x) = 5x + 1
Step-by-step explanation:
Given data
We have the following expressions to work with
f(x) = 2x − 6 and
g(x) = 5x + 1
say the value of x = 3
let us put x into the two expressions above and compare the output
f(x) = 2*3 − 6= 6-6= 0
g(x) = 5*3 + 1= 15+1= 16
Hence the second function has the greatest output
Find the lettered angles in each of the following.
( where a point o is given , it is the centre of the circle) .
Answer:
q = 80 degrees
r = 70 degrees
s = 10 degrees
t = 70 degrees
u = 40 degrees
v = 60 degrees
Step-by-step explanation:
starting with the fact that all angles in any triangle always sum up to 180 degrees :
q = 180 - 60 - 40 = 80 degrees
r = 180 - (60+10) - 40 = 180 - 70 - 40 = 70 degrees
the triangle 40-60-q and v-u-blank are similar triangles. your can say the smaller triangle is just a projection of the large triangle through the focal point at angle q.
that means the angles must be equal.
v = 60 degrees
u = 40 degrees
similar for 10-r-blank and t-s-blank.
s = 10 degrees
t = 70 degrees
u=60°
v=40°
q=80°
r=70°
s=70°
t=10°
Answer:
Solution given:
t=10°[inscribed angle on a same chord or arc is equal]
V=40°[inscribed angle on a same chord or arc is equal]
u=60°[inscribed angle on a same chord or arc is equal]
AGAIN;
40+60+10+r=180°[sum of interior angle of triangle]
r+110°=180°
r=180°-110°
r=70°
again
r=s=70°[inscribed angle on a same chord or arc is equal]
again
q=r+10°[exterior angle is equal to the sum of two opposite interior angle]
q=70+10=80°
