Multiplication is done before division.
So, multiply 1.21*2 for the first problem, and 1.20*2 for the other 2 problems.
1.
24/(1.21)2 becomes 24/2.42
24/2.42= 9.9173553719 (or 9.92 rounded, or 9.9)
2.
29/(1.20)2 becomes 29/2.4
29/2.4= 12.0833333333 (or 12.08 rounded, or 12.1)
3.
40/(1.20)2 becomes 40/2.4
40/2.4= 16.6666666667 (or 16.7 rounded)
I am not sure if you have to round your answers up, so I provided those answers as well in case.

7) Write the equation of the line that passes through (-4,4) and (2,10)
Answer:
y=x+8
Step-by-step explanation:
m=y2-y1/x2-x1
First you choose one of your coordinate points to be 1 and one to be 2.
Then you substitute your x and y values into the equation above.
That way, you find the slope of the line.
For example i chose (-4,4) to be point 1 and (2,10) to be point 2.
m=10-4/2-(-4)
m=6/6
m=1
Next, you write the equation of a line.
y=mx+b
and you substitute the x and y values of one coordinate point into the equation. You also put m(slope) in, the one you just solved for.
I chose to substitute (2, 10)
10= 1(2)+b
Next, you solve for b
10=2+b
10-2=b
b=8
Now that you have b and your slope, you substitute those into the second equation
y=1x+8 or
y=x+8

Answer: 35/18 or 1 17/18
Make both of the fractions improper by multiplying the denominator of one fraction by its whole number and add on the extra from the numerator. So 3x8 is 24, add the 1 is 25 to get 25/3 for the first fraction and 7 x 4 is 28, add 2 to gives us 30/7 (remember all denominators stay the same as in the question).
Now follow the steps in KFC (or KCF)
Keep the first fraction (25/3)
Change the sign to a x
Flip the last fraction (30/7 becomes 7/30)
Now we get 25/3 x 7/30
Multiply along the top and bottom to get 175/90 which then simplifies to 35/18 cuz we divided the top and bottom by 5. We can change 35/18 to a mixed number: 1 17/18
Triangles ABD and XYZ are similar .Find the length of the segment XZ.
Answer: 2.4
Step-by-step explanation:
Because they are similar, the lengths of the sides will have the same ratio.
We will use side AB and side XY since it shows both sides.
This shows that the ratio is 3:4
We can then use that to find out that XZ also uses the ratio 3:4
3.2 / 4 = 0.8
0.8 * 3 = 2.4
XY is equal to 2.4

What is the answer of the 5? I don’t know how to do this, please help me! ☹️☹️☹️☹️☹️
Step-by-step explanation:
the perimeter is easy.
it is an isoceles triangle, that means both sides are equally long (10 units).
the length of the baseline we can read directly off the coordinates of P and Q.
both are on the same horizontal grid line y = 1. so, the difference in x is their distance : 8 - -8 = 8+8 = 16
so, the perimeter is 10 + 10 + 16 = 36 units.
now, for k :
k is the height of the triangle + 1 (as the baseline is at y=1 and not at 0).
we can get the height by using Pythagoras :
c² = a² + b²
c is the Hypotenuse (the baseline) of the dude opposite of the 90° angle.
the triangle we use for this is
PR, half of PQ and the height of the main triangle, with PR being the Hypotenuse.
so,
10² = (16/2)² + height² = 8² + height²
height² = 10² - 8² = 100 - 64 = 36
height = 6
therefore, k = 6 + 1 = 7

BD=4x+5 and BF=9x
x=
Based on the centroid theorem, the value of x is: 2.5.
What is the Centroid Theorem?The centroid theorem states that, the centroid of a triangle equals two-third of the distance from each midpoint of a triangle to each vertex.
Given:
BD = 4x + 5
BF = 9x
Thus:
BD = 2/3(BF)
Substitute4x + 5 = 2/3(9x)
4x + 5 = 6x
4x - 6x = -5
-2x = -5
x = 5/2
x = 2.5
Therefore, based on the centroid theorem, the value of x is: 2.5.

So the sum of 128 and x+10 is on a straight line which is 180º right?, so:
x + 10 + 128 = 180
x = 180 - 128 - 10
x = 42º
Answer:
42
Step-by-step explanation:
x +10 +128 = 180 {Linear pair}
x + 138 = 180
x = 180 - 138
x = 42
