Answer:
5/6
Step-by-step explanation:
The density of gold is 19.3 grams per cubic centimeter. Rachel determines that the density of a coin is 18.7 grams per cubic centimeter. Based on this evidence, she concludes that the coin is not gold or at least not entirely gold. Is this an example of inductive or deductive reasoning?
Answer:
The reasoning is a deductive.
The reason is because the pattern of thought is logical, here, scientific methods ( i.e mathematically obtaining and comparing the density of the coin and the gold ) are used to support the conclusion.
Step-by-step explanation:
Gnerally the reasoning is a deductive.
The reason is because the pattern of thought is logical and scientific methods (eg mathematical equation (formula for density)) are applied to arrive at the conclusion.
what is the slope of the line that goes through the points (2,-1) and (6,1)
Answer: The slope is [tex]\frac{1}{2}[/tex].
Step-by-step explanation:
1. You set up your Slope Formula [tex]M=\frac{y2-y1}{x2-x1}[/tex].
2. Substitue your points into the formula.[tex]M=\frac{1--1}{6-2}[/tex].
3. Once you substitute, you will solve the equation[tex]M=\frac{2}{4}[/tex].
4. Simplify the equation if you have to [tex]M=\frac{1}{2\\}[/tex].
Triangle FUN, with vertices F(−2, 4), U(0, −5), and N(−3, −8) was dilated to form triangle PET with vertices P(−1.6, 3.2), E(0, −4), and T(−2.4, −6.4).Which scale factor was used? A. 1.25
B. −1
C. 2/3
D. 0.8
Suppose these statements about two triangles are
true:∠G=∠S,∠R=∠,and ∠M=∠N. Which statement is correct? Select all that apply.
A.The sides are congruent.
B.The sides are proportional.
C. ΔGRM is similar to ΔNST
D. ΔMGR is similar to ΔNST
Answer:
For first question answer is D.0.8
For second question answer is D.ΔMGR is similar to ΔNST.
Step-by-step explanation:
Here triangle FUN is dilated to get triangle PET
So, let's take F and P.
F(-2,4) and P(-1.6, 3.2)
Let's find the scale factor by dividing the coordinates.
Scale factor =[tex]\frac{-1.6}{-2} =0.8[/tex]
Using y coordinates of the same points
Scale factor =[tex]\frac{3.2}{4} =0.8[/tex]
So, scale factor is 0.8
Now, for the second problem
<G= <S
<R= <T
<M=<N
So, the corresponding angles are congruent when two triangles similar.
So, we can say ΔMGR is similar to ΔNST.

The sum of 3 consecutive numbers is 72. What is the largest of these numbers?
23
25
26
28
Answer:
25
Step-by-step explanation:
23+24+25=72
hope i helped!! :)
( if it is right, pls mark brainliest!!)
Answer:
25
Step-by-step explanation:
let x represent the first consecutive number.
let x+1 represent the second consecutive number.
let x+2 represent the third consecutive number.
x + x+1 + x+2 = 72
3x + 3 = 72
3x = 72 - 3
3x = 69
3x/3 = 69/3
x= 23
first number= x = 23
second number = x+1
= 23+1
=24
third number= x+2
=23+2
=25
the largest of these numbers is 25

Step-by-step explanation:
Mary and her family ordered a large pizza for dinner. Half of the pizza is plain and half of the pizza has pepperoni. Mary loves pepperoni so she ate 1/5 of the full pizza (all of which had pepperoni). How much of the remaining full pizza has pepperoni?
Answer:
3/10 of the renaming full pizza has pepperoni
Step-by-step explanation:
Here, we want to calculate how much of the remaining pizza had pepperoni.
From the question, 1/2 has pepperoni and 1/2 is plain without pepperoni
she eats 1/5 of the pizza having pepperoni, this means that she is actually left with some parts is the half having pepperoni
The actual of the half remaining with pepperoni will be 1/2 - 1/5 = 3/10
This means that 3/10 of the remaining full pizza has pepperoni

What is the equation in point slope form of the line that passes through the point (3, 1) and has a slope of –2?
Drag and drop the appropriate number, symbol, or variable to each box.
Answer:
y = -2x + 7
Step-by-step explanation:
you can use y–y1=m(x–x1) but I just plug straight into y=mx+b and solve from their (much simpler)so plugging the numbers in y=mx+b it will become 1 = -2(3) + bsimplify so 1 = -6 +b or b – 6 = 1add six to both sides to get b=7slope or m is -2 and b or y-intercept is 7y= -2x+7Here are the correct answers for these questions below

Integrated math 2 NEED HELP ASAP
Answer:
56
Step-by-step explanation:
Since the 2 triangles are congruent, the ratio of their sides are also equal. Therefore, we can set up an equation:
[tex]\frac{10}{16}=\frac{3x+2}{5x+1}\\\frac{5}{8}=\frac{3x+2}{5x+1}\\5(5x+1)=8(3x+2)\\25x+5=24x+16\\x=11[/tex]
Now that we know x, we can plug in x as 11 into the expression of DE to solve for DE:
5*11+1
=56

what are the solutions to this quadratic equation?
x^2+10=0
Answer:
Correct choice: C. [tex]x=\pm\sqrt{10}\mathbf{i}[/tex]
Step-by-step explanation:
The quadratic equation to solve is:
[tex]x^2+10=0[/tex]
Since this equation is incomplete, we can solve it without using the quadratic solver formula.
Subtracting 10:
[tex]x^2=-10[/tex]
Taking square root:
[tex]x=\pm\sqrt{-10}[/tex]
Recall the square root of a negative number leads to imaginary solutions where the Unit Imaginary Number (i) is used, where:
[tex]\mathbf{i}=\sqrt{-1}[/tex]
The solutions to the equation are:
[tex]x=\pm\sqrt{10}\mathbf{i}[/tex]
Correct choice: C. [tex]x=\pm\sqrt{10}\mathbf{i}[/tex]
