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

Answer:
Step-by-step explanation:
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
A circle’s circumference is approximately 76 cm.
Estimate the radius of the circle.
Use 3.14 for .
Round your answer to the nearest whole number.
Answer: Area= 459.73cm^2
Step-by-step explanation: Circumference of a circle is 2πr
76=2×3.14×r
r= 76÷(6×3.14)
r=12.10
Area of a circle= πr^2
Area= 3.14×(12.10)^2
Area= 456.73cm^2

And how much does he earn in 8 hours?
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

a poultry farmer sold 1/2 of his eggs and ate 1/3 of the remainder if he has 400 left how many eggs had he originally
Answer:
2400 eggs
Step-by-step explanation:
1. To find out how many eggs the poultry farmer had originally, we have to reverse the steps of him selling and eating this eggs.
This means to basically multiply 400 by the reciprocal (inverse) of 1/2 and 1/3.2. (Solving)
[tex](2)(3)(400)[/tex] [tex](6)(400)[/tex] [tex]2400[/tex]Therefore, he had 2400 eggs originally.

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

0.25 : 1/2 = 6 : x
0.25 : 0.5 = 6 : x
0.5 = 6 : x
x = 6 : 0.5

Point D is the centroid of △ABC. Use the given information to find the value of x.
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.
