Answer and Explanation: No,
Step-by-step explanation:
one-third is NOT more than one-half. One-half is more than one-third. Because the two fractions, 1/3 and 1/2, have the same numerator (remember, the numerator is the number on top), they are easy to compare.
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

P.E.M.D.A.S (order of operations)
Parentheses, Exponents, Multiplication and Division, Addition and Subtraction (From left to right)
M=Multiplication
D=Division
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

Market researchers were interested in the relationship between the number of pieces in a building-brick set and the cost of the set. The researchers collected information from a survey and used it to obtain the regression equation y = 0.08x + 1.20, where x represents the number of pieces in a set and y is the predicted price (in dollars) of the set. What is the predicted price of a set that has 2,520 pieces?
A. $202.80
B. $2,017.20
C. $3,024.08
D. $31,485
Answer:
A. $202.80 EDGE
Step-by-step explanation:
The predicted price of a set that has 2,520 pieces is $202.8.
The correct option is (A).
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
y = 0.08x + 1.20
where x represents the number of pieces in a set and y is the predicted price.
So, for x= 2520 pieces the predicted price is
y= 0.08(2520)+ 1.20
y= 201.6 + 1.5
y= $202.80
Hence, the predicted price is $202.8.

A triangle has two sides of length 19 and 3. What is the smallest possible whole-number length for the third side?
Answer:

ten times the reciprocal of a number equals 5 times the reciprocal of 3
The reciprocal of a whole number is a fraction with the whole number as the denominator.
Set up the equation:
10 * 1/x = 5 * 1/3
Simplify:
10/x = 5/3
Multiply both sides by 3:
30/x = 5
multiply both sides by x:
30 = 5x
Divide both sides by 5:
x = 6

What is the lowest single score (percent) you could get on one of the five example and still receive an A? How did you calculate your score? Explain it to your friends who believes the only way to receive an A is by earning an A on every exam. Is your friend right? Why or why not?
Answer:
Well I'm assuming some things based on my logic because I don't see the "five examples" but the normal lowest grade you can get and still get a A would be 90.0%. In order to get a A on a exam you need to understand the content of the exam. Some kids get A's on every exam for every class because they understand the content of their classes. Others get B's, C's, D's, and F's because they don't understand the content. Understanding content has nothing to do with you passing exams but how much effort you put into the class and studding.
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

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
