Shirts are on sale at a price of $50 for 4. How many shirts can be purchased for $125?
A) 2 B) 8 C) 9 D) 10
Answer:
10 shirts
Step-by-step explanation:
We can use a ratio to solve
50 dollars 125 dollars
-------------------- = -------------------
4 shirts x shirts
Using cross products
50 *x = 4 * 125
50x = 500
Divide each side by 50
50x/50 = 500/50
x = 10
Answer:
D. 10
Brainliest, please!
Step-by-step explanation:
50/4 = 125/x
25/2 = 125/x
25 = 250/x
x = 250/25
x = 10

−1 4/5−(−2 7/8)
4 3/4−(−1 1/12)
−1 4/5−(−2 7/8)
3 1/3-5
−1/3−(−1/2
Answer:
1) 43/40
2) 35/6
3) 43/40
4) -5/3
5) 1/6
Step-by-step explanation:
1) -1 4/5 = -(1*5 +4)/ 5= -9/5
or 1= 5/5 so -1 4/5= -( 5/5+ 4/5)=-9/5
-2 7/8= -(2*8+7)/8=-23/8
=> -9/5 - ( -23/8)= -9/5 + 23/8 = (( -9*8)+(23*5))/40= (-72+ 115)/40
= 43/40
2) 4 3/4= (4*4+3)/4= 19/4
-1 1/12= -(1*12+1)/12= -13/12
=> 19/4 - (-13/12)= 19/4 + 13/12 = ((19*3)+13)/12= (57+13)/12= 35/6
3) same like 1)
4) 3 1/3 = (3*3+1)/3= 10/3
=> 10/3 -5= (10- 3*5)/3= (10-15)/3= -5/3
5) -1/3 + 1/2= ((-1*2)+(1*3))/6 = (-2+3)/6= 1/6
Ahmad travelled 1/4 of a journey by Train X, 3/4 of the remainder by Train Y and the remaining 10km by Train Z. a) How far did Ahmad travel by Train Y? b) What was the total distance that Ahmad travelled?
Hey there! I'm happy to help!
Train X takes out 1/4 of our journey.
Now, we have 3/4 of the journey left.
Train Y takes 3/4 of the last 3/4 of the journey. How much is that, let's just multiply the fractions!
3/4*3/4= 9/16
So, 9/16 of the total journey is done by Train Y.
A fourth of 16/16 is 4/16, so that leaves us with 3/16 left to go.
So, 3/16 of our total distance is equal to 10 km. Let's call our total distance d and set this up as an equation.
3/16d=10
Divide both sides by 3/16.
d= 53 1/3
We also remember that Train Y gave us 9/16 of our total journey, so we can multiply this by our total distance to see how far train Y went.
53 1/3 * 9/16= 30
So, A. Ahmad traveled 30 miles by Train Y and B. his total distance traveled is 53 1/3 miles.
Have a wonderful day and keep on learning! :D

Which statement describes the graph of f(x) = –4x3 – 28x2 – 32x + 64?
The graph crosses the x-axis at x = 4 and touches the x-axis at x = –1.
The graph touches the x-axis at x = 4 and crosses the x-axis at x = –1.
The graph crosses the x-axis at x = –4 and touches the x-axis at x = 1.
The graph touches the x-axis at x = –4 and crosses the x-axis at x = 1.
It should be noted that a statement that describes the graph of f(x) = -4x3 - 28x2 - 32x + 64 will be;
D. The graph touches the x-axis at x = -4 and crosses the x-axis at x = 1.
What is a graph?It should be noted that a graph is a diagram that shows the relationship between two or more sets of numbers.
Given that;
The function is,
⇒ f(x) = - 4x³ - 28x² - 32x + 64
Now, We can draw the graph of the function,
We get;
The x-axis at x = -4 and crosses the x-axis at x = 1.
In this case, the statement that describes the graph of f(x) = -4x3 - 28x2 - 32x + 64 will be is that the graph touches the x-axis at x = -4 and crosses the x-axis at x = 1.

Three consecutive vertices of a parallelogram are (– 2, 1); (1, 0) and (4, 3). Find the coordinate of the fourth vertex and find the area of the parallelogram.
Answer:
D(1,4) - the fourth vertex, the area is equal to 12
Step-by-step explanation:
A(2,-1), B(1,0),C(4,3), They are consecutive, we need to find the point D, find the midpoint of AC (O)
xo= (xA+xc)/2 x0= (-2+4)/2=1
y0=(yA+yC)/2 y0= (1+3)/2=2
0(1,2)
O is the midpoint of BD, so let's find the vertex D
X0= (xB+xD)/2 1= (1+xD)/2 xD=1
y0= (yB+yD)/2 2= (0+yD)/2 yD=4
D(1,4)
the vector DA is (-2-1, 1-4)= (-3,-3)
the vector DC is (4-1, 3-4)= (3,-1)
The modul of DC is sqrt ((-3)^2+(-3)^2)= 3*sqrt2(the length of the side Dc)
The modul of DA is sqrt (3^2+(-1)^2)= sqrt10(the length of the side DA)
cosD= (-3*3+(-3)(-1))/3*sqrt2*sqrt10=-6/3*2*sqrt5=-1/sqrt5
sinD= sqrt (1- 1/5)=2/ sqrt5
S=3sqrt2*sqrt10*2/sqrt5= 12

Answer:
11,4 > 11 > 9,8 > 1
Step-by-step explanation:
To list the numbers from smallest to largest we need to determine the value of them in same/similar format
11 and 1 is in same format
The approximate value of [tex]\pi ^{2}[/tex] 9.8
the root of [tex]\sqrt{121}[/tex] = 11
the root of [tex]\sqrt{130}[/tex] is = 11.4 approximately
Now we have them as real numbers we can evaluate
11,4 > 11 > 9,8 > 1 we don't need to write 11 twice but if needed we can write is as:
11,4 > 11 = 11 > 9,8 > 1

Step-by-step explanation:
[tex]here \: c \: is \: the \: \: mid \: point \\ so \: bc = cd \\ 6x - 16 = 4x + 10 \\ x \: terms \: togather \\ 6x - 4x = 10 + 16 \\ 2x = 26 \\ x = \frac{26}{2} \\ x = 13 \\ thank \: you[/tex]
Answer:
x=13
Step-by-step explanation:
BC = CD
6x-16 = 4x+10
Subtract 4x from each side
6x-16-4x = 4x+10-4x
2x-16 = 10
Add 16 to each side
2x-16+16 = 10+26
2x = 26
Divide by 2
2x/2 =26/2
x = 13
The angles of a quadrilateral are in the ratio 1:2:3:4. The smallest and the largest angle are
urgent pls answer asap
thank you
Step-by-step explanation:
Let the angles of quadrilateral be
X, 2x, 3x, 4x
Sum of all angles of quadrilateral = 360
X+2x+3x+4x = 360
10x = 360
X = 360/10 = 36
Ans: the four angles are
X = 36
2x = 2 X 36 = 72
3x = 3 X 36 = 108
4x 4 X 36 = 144
