Answer:
The proportion that can be used is
2 inches 30 inches
15 miles x
Step-by-step explanation:
If 15 miles is 2 inches and 30 divided by 2 is 15, you have to multiply 15 by 15 to figure out how many miles 30 inches is. Because 15 x 15 = 225, 30 inches is 225 miles. Therefore, x = 225.

3. Jade is checking one of her zeros to a quadratic function. Her steps are shown. What must be true of this value?
Check = 2
0= (2)2 – 2(2) – 3
0= 4 - 4 - 3
0 -3
Answer:
Option C: since a false statement resulted, it means x = 2 is not a zero.
Step-by-step explanation:
We are told that She is checking the zeros of her quadratic function.
Now the zeros of a quadratic function f(x) are values of that make f(x) = 0. In order words they are basically the roots of the function or the x-intercept.
Now, she has tried x = 2 into her quadratic equation and it didn't yield zero.
Since it yielded -3 and not 0, it means 2 is not a zero of the quadratic function.

Pattern: 4, 10, 18, 28, 40, 54, 70, 88, 108, 130
Since the second difference is constant in the pattern above, the algebraic
expression will have degree 2. In an expression of degree 2, the largest
exponent is 2. Therefore, we know that the expression for this pattern must
include n^2. What is the algebraic expression for the nth term in this pattern?
Answer:
The algebraic expression for the nth term in this pattern is n^2 + 3n
Step-by-step explanation:
We want an algebraic expression for the nth term in this pattern.
Like we are told, there must be an expression that includes the term n^2
So therefore;
We need to express each of the terms to include the n^2 term
Kindly note that the n notation will represent the term number of the value we are considering. Let’s take it one after the other.
for 4; 1^2 + 3(1)
For 10; 2^2 + 3(2)
For 18; 3^3 + 3(3)
For 28; 4^2 + 3(4)
For 50; 5^2 + 3(5)
So the nth term will be;
n^2 + 3n

By using the principles of fractions, we can find out that the models represent the problem 3/4 × 3.
Define fractions?A number that represents a percentage of a whole serves as the mathematical representation of a fraction. Fractions can be thought of as any number, any amount, or a portion of an object.
A pizza that has been cut into eight equal pieces. The notation 1/8, which denotes that we are speaking of one portion out of 8 equally sized portions, can be used to refer to a single portion of the pizza.
It indicates one equal part in eight. Furthermore, it can be written as: 1/8
It will be written as 2/8 if we choose to have 2 portions of the pizza. Similar to how we would write 6/8 as a fraction if we were referring to 6 portions of this pizza.
Now here in the question, 3 parts are selected out of 4.
So that suggests it is 3/4.
As there are 3 circular models, so the representation will be as:
3/4 × 3.

Find the indicated conditional probability using the following two-way table
P(Take the bus|Junior)=[?]
round to the nearest hundredth.
Answer:
P(Take the bus|Junior)=0.57
Step-by-step explanation:
Conditional Probability
Is a measure of the probability of the occurrence of an event, given that another event has already occurred. If event B has occurred, then the probability that event A occurs is given by:
[tex]{\displaystyle P(A\mid B)={\frac {P(A\cap B)}{P(B)}}}[/tex]
Where [tex]P(A\cap B)[/tex] is the probability that both events occur and P(B) is the probability that B occurs.
The two-way table shows statistics of students and we are interested to find the probability that, given the student is a junior (let's call it event B), they also take the bus (Event A). Thus, the probability we need to calculate is:
[tex]\displaystyle P(A\mid B)={\frac {P(A\cap B)}{P(B)}}[/tex]
Checking on the table, we can see that both events occur when the row and the column of both events coincide, i.e. 20 students out of a total of 100 students in total. Thus:
[tex]\displaystyle P(A\cap B)=\frac {20}{100}=0.2[/tex]
The probability that a student is classified as Junior is
[tex]\displaystyle P(B)=\frac {35}{100}=0.35[/tex]
The conditional probability is:
[tex]\displaystyle P(A\mid B)=\frac {0.2}{0.35}=0.5714[/tex]
P(Take the bus|Junior)=0.57

Answer: angle x is 52°
Assuming the line JK is parallel to HI. That should be given.
Step-by-step explanation:
Angle JKA is congruent to angle HIA, so both measure 62°
Add measure of AHI to JKA.
66+62= 128.
Angles of a triangle always add up to 180° so you can subtract 128 from 180 to find x.
180-128= 52°
What value of x makes this equation true?
0.6x - 5 = 0.1x + 7
Answer:
x=24
Step-by-step explanation:
0.6x - 5 = 0.1x + 7
add 5 to both sides:
0.6x = 0.1x + 12
take away 0.1x from both sides:
0.5x = 12
divide both sides by 0.5
x = 12÷0.5
x=24

Answer:
(-7, 5)
Step-by-step explanation:
Since both of them are equal to y, you could just set them equal to each other.
5/7x + 4 = -1/7x - 2
6/7x = -6
x = -7
Now just plug x back to one of the equations:
y = -1/7*(-7) - 2 = 7 - 2 = 5
Therefore, the solution to the system is (-7, 5)
