THIS IS THE COMPLETE QUESTION BELOW;
young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly. He started at 909090 kilograms and gained weight at a constant rate. After 888 months, he weighed 138138138 kilograms. Let W(t)W(t)W, left parenthesis, t, right parenthesis denote the sumo wrestler's weight WWW (measured in kilograms) as a function of time ttt (measured in months). Write the function's formula.
Answer:
W=6t+90
Step-by-step explanation:
We know that a linear equation in slope takes the form
y= mx+ c
where
m is the slope
c is the y-coordinate of the y-intercept
Let us denote W as the sumo weight in kg then
t as the time in months
Then forming a linear equation from this knowing t is a dependent variable then
W(t)= mt+90
But here we know that is our slope, W was given as 138kg and t is 8 months.
We we substitute this values in the equation we have
138= 8m+90
8m= 138-90
8m=48
m=6kg/month
Therefore, the function formula is W(t)= 6t+90
Determine if the triangles are congruent.
Answer:
Answer to number 3:
Yes, because these two are similar triangles for sure so all their respective angles are equal in measure, and two pairs of sides are congruent to each other, so the third one must be congruent too.
Find th slope of the line passing through the points (5,8) and (6,12)
Answer:
Slope= 4
Step-by-step explanation:
y2-y1/x2-x1
5=x1 8=y1 etc.
12-8/6-5
=4/1
Answer:
The slope of the line is 4.
Step-by-step explanation:
To solve for the slope of the line, use the rise over run formula. The rise over run formula is a measure of how much something changes vertically compared to how much it changes in the horizontal direction. The rise over run formula calculates the difference between the two points in the vertical direction (rise) and then divide it by the difference in the horizontal direction (run). The formula looks like [tex]\frac{rise}{run}[/tex], but in terms of finding a slope, it looks like [tex]\frac{y_{2}-y_{1} }{x_2-x_1}[/tex].
For finding the slope of this line with the points (5,8) and (6,12), start by writing down the information given from the question.
[tex]y_2=12[/tex]
[tex]y_1=8[/tex]
[tex]x_2=6[/tex]
[tex]x_1=5[/tex]
Next, plug in the information given from the question into the formula, and the formula will look like [tex]\frac{12-8}{6-5}[/tex]. Then, simplify the equation, which will look like [tex]\frac{4}{1}=4[/tex]. The final answer will be 4.

Answer:
PY = 14.5
Step-by-step explanation:
The diagonals of a rectangle are congruent and bisect each other, thus
XZ = WY , that is
4x - 1 = x + 7 + x + 7
4x - 1 = 2x + 14 ( subtract 2x from both sides )
2x - 1 = 14 ( add 1 to both sides )
2x = 15 ( divide both sides by 2 )
x = 7.5
Thus
PY = x + t = 7.5 + 7 = 14.5
Step-by-step explanation:
py is equal to wp because the figure is a rectangle.x+7+x+7= 4x-1
2x+14=4x-1
14= 2x-1
15= 2x (divide)
x = 7.5
wp= 7.5cm

Rewrite the following equation in standard form.
y = -7x - 1
Standard form is written Ax + By = C where A, B, and C are all integers.
In other words, no fractions.
Also, the A or the coefficient of the x term must be positive.
The only thing we need to do is add 7x to both sides to get 7x + y = -1.
So 7x + y = -1 is our answer.
Answer: 7x+y=-1
Step-by-step explanation:
Add 7x to both sides
Solve x^3 = 1 over 8.
1 over 2
±1 over 2
1 over 4
±1 over 4
Answer:
x = 1/2
Step-by-step explanation:
x^3 = 1/8
Take the cube root of each side
x^3 ^ (1/3) = (1/8)^ (1/3)
Rewriting 8 as 2^3
x^3 ^ (1/3) = (1/2^3)^ (1/3)
x = 1/2
x³ = 1/8
8 can be written as 2³
x³ = 1/2³
(x)³ = (1/2)³
When exponents are same bases are taken and exponents are eliminated
x = 1/2

Jorge finds that 56% of his 75 classmates like salsa music and 80% of his 60 relatives like salsa music. How many more of Jorge's relatives,as compared to his classmates, like salsa music?
Answer:
6 more
Step-by-step explanation:
Find 56% of 75 first
75/x=100/56
(75/x)*x=(100/56)*x
75=1.78571428571*x
(1.78571428571) to get x
75/1.78571428571=x
42=x
x=42
Then Find 80% of 60
60/x=100/80
(60/x)*x=(100/80)*x
60=1.25*x
60/1.25=x
48=x
x=48
Subtract 48 by 42
=6
How do I even start this? And how to i order the equation to solve
[tex]f(g(h(x)))=f(g(\sqrt x))=f(\sqrt x-1)=\boxed{(\sqrt x-1)^4+4}[/tex]
This is because
[tex]h(x)=\sqrt x[/tex]
[tex]g(x)=x-1[/tex]
[tex]\implies g(h(x))=\sqrt x-1[/tex]
(that is, replace any instance of x in the definition of g with √x )
and
[tex]f(x)=x^4+4[/tex]
[tex]\implies f(\sqrt x-1)=(\sqrt x-1)^4+4[/tex]
(replace any x in f with √x - 1)
Also acceptable:
[tex](\sqrt x-1)^4+4=((\sqrt x)^4-4(\sqrt x)^3+6(\sqrt x)^2-4\sqrt x+1)+4[/tex]
[tex]=\boxed{x^2-4x\sqrt x+6x-4\sqrt x+5}[/tex]
(assuming x is not negative)

Answer:
2/7
Step-by-step explanation:
This is basically asking how many 7/10 's fit in 1/5. Or 1/5 divided by 7/10.
1/5 divided by 7/10 is the same as 1/5 times the reciprocal, 10/7. Therefore it is 1/5*10/7, or 10/35.
That simplifies to 2/7.

What is the value of a in the given figure
Answer:
soln
let one side be c
let another side be d
then
40=d(vertically opposite angle)
5a =c(vertically opposite angle)
again
c+90=180(being linear pair)
or, c=180-90
therefore, c=90
finally
let c be a
5a=5×90
=450
Answer:
a = 10
Step-by-step explanation:
CF is a straight line , so the 3 angles on it sum to 180° , then
∠ BOA = 180° - (90 + 40)° = 180° - 130° = 50°
∠ DOE = ∠ BOA ( vertical angles ) , then
5a = 50 ( divide both sides by 5 )
a = 10

The following diagram shows the lines x – 2y – 4 = 0, x + y = 5 and the point P(1, 1). A line is drawn from P to intersect with x – 2y – 4 = 0 at Q, and with x + y = 5 at R, so that P is the midpoint of [QR].
Find the exact coordinates of Q and of R.
Answer:
Q(2/3, -1 2/3)R(1 1/3, 3 2/3)Step-by-step explanation:
Let (a, b) represent the coordinates of point Q on line x -2y -4 = 0. Then we know that ...
a -2b -4 = 0
a -2b = 4
__
If P is the midpoint of QR, then ...
R = 2P -Q = 2(1, 1) -(a, b) = (2 -a, 2 -b)
We know this point satisfies the equation for the other line:
x + y = 5
(2 -a) +(2 -b) = 5
a + b = -1 . . . . . . . . . . . rearrange to standard form
__
To find the solution to these two equations, we can subtract the first from the second:
(a +b) -(a -2b) = (-1) -(4)
3b = -5
b = -5/3
a = -1 -1b = -1 -(-5/3) = 2/3
The point Q is (a, b) = (2/3, -5/3).
The point R is ...
R = (2 -a, 2 -b) = (2 -2/3, 2 -(-5/3)) = (4/3, 11/3)
The exact coordinates of Q and R are ...
Q(2/3, -5/3), R(4/3, 11/3)

Comment on the GeoGebra solution
The points can be found by reflecting either line across point P. Where that reflected line intersects the other line is one of the points of interest. Of course, the other is its reflection in P. You may recognize the equation for line b' (hidden in the diagram) as matching the second equation we derived above.

Ruben goes to a shop to buy 24.5m of cloth and 13.5m ribbon. The cloth costs Rs.85.40 per metre and the ribbon costs Rs.8.5 per metre. If he pays Rs. 2300 to the shopkeeper, how much money will he get back?
Answer:
Rs.92.95
Step-by-step explanation:
Given the following :
Metres of cloth purchased = 24.5m
Metres of ribbon = 13.5m
Cost of cloth per metre = Rs.85.40
Cost of Ribbon per metre = Rs.8.50
Total amount given to shopkeeper = Rs. 2300
how much money will he get back?
Total cost of cloth:
Cost per metre * number of metres
85.40 * 24.5 = Rs. 2092.30
Total cost of Ribbon :
Cost per metre * number of metres
8.50 * 13.5 = Rs. 114.75
Total cost of goods purchased :
Rs. (2092.30 + 114.75) = Rs. 2,207.05
Amount of change :
Rs. (2300 - 2207.05) = Rs.92.95

which of the following isthe√×51? answer is A .0-1
Find the measure of a.
Answer:
50 degrees
Step-by-step explanation:
We know that an inscribed angle in a circle is 1/2 the arc that it inscribes. So, therefore the arc is inscribed by the 25 degrees is 50. Assuming that the center of the circle is O, the center angle will be the arc measure. Knowing this, angle a is 50 degrees. If you're curious about all these theorems, they can be proved using similar triangles.
fyi, using the same logic, angle b is 25 degrees
can someone help me with this graphical method equation 3x + 5y = -2 7x - 8y = 15
Answer:
x = 1
y = -1
Step-by-step explanation:
3x + 5y = -2
7x - 8y = 15
=> -8y = 15 - 7x
=> -y = 15/8 - 7/8x
=> y = -15/8 + 7/8x
3x + 5(-15/8 + 7/8x) = -2
=> 3x -75/8 + 35/8x = -2
=> 24/8x - 75/8 + 35/8x = -16/8
=> 59/8x - 75/8 = -16/8
=> 59/8x = 59/8
=> x = 59/8 x 8/59
=> x = 472/472
=> x = 1
x = 1
So, 3x + 5y = -2
=> 3 (1) + 5y = -2
=> 3 + 5y = -2
=> 5y = -5
=> y = -5/5
=> y = -1
So, x = 1
=> y = -1
