Answer:
103 and 104
Step-by-step explanation:
Two consecutive numbers
x and x + 1
3 times the first number and 2 less than the second number = 411
3x + (x + 1) - 2 = 411
3x + (x + 1) - 2 = 411
combine like terms
4x - 1 = 411
4x = 412
dividde both sides by 4
x = 103
x + 1 = 104
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.

A triangle has two sides of length 19 and 3. What is the smallest possible whole-number length for the third side?
Answer:
17
Step-by-step explanation:
You have length 19 and 3:
19-3 = 16 AND 19+3=22
You have a range of 16 and 22 and the smallest number between this specific interval is 17, you do not include 16 or 22 in the interval.
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

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.

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.

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

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

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

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.
