Answer:
The bike will cost $481.50
because
10% off of 500 is 50
so 500 - 50 = 450
Now include the sales tax which is
450 * 0.07 = 31.5
Now add the two totals to get
$481.50
f(x) = 3x + 1, solve for x when f (x) =7.
Answer: x=2
Step-by-step explanation:
Given
f(x)=3x+1
f(x)=7
Combine two equations by substitution
3x+1=7
Subtract 1 on both sides
3x+1-1=7-1
3x=6
Divide 3 on both sides
3x/3=6/3
x=2
Hope this helps!! :)

Answer:
C
Step-by-step explanation:
We have congruent angles in the middle and 2 sides are congruent as well which makes (Angle-Side-Side) which doesn't work for congruent triangles.
C. is the answer
2 givens and then we have CB = CB which is the reflexive property. I haven't heard of (definition of midpoint) but as long as there aren't any more answers except the 3 shown above it should be correct.
A sphere has a volume of 457 in. What is the radius of the sphere? Use 3,14 for pi. Round to the nearest whole number.
Answer:
4.78
Step-by-step explanation:
we know volume =4/3 pie r³
=4/3×3.14×r³=457
=r³=(457/4.19)
r³=109.16
r³=(4.78)³
r=4.78 ■
It took the football team 5 h to travel from Titletown, a total distance of 1320 km. Part of the trip was by bus and the remainder by plane. The bus averaged 40 km/h and the plane 600 km/h. How many hours were spent travelling by bus?
Answer:
It took 2 hours by plane
Step-by-step explanation:
let bus is represented by x and plane is represented by y
the total distance of bus and plane will be represented by equation:
40 x + 600 y = 1320 (1)
the total time taken by bus and plane will be represented by:
x + y = 5 (2)
solving equations (1) and (2) simultaneously:
Multiply by 40 on both sides in eq (2) and then subtract (1) and (2)
40 x + 600 y = 1320
40 x + 40 y = 200
_______________
560 y = 1120
y = 1120/ 56
y= 2
since plane is represented by y so, the time they spent travelling by plane is 2 hours.
What is the equation of the line that passes through the point (-4,-7) and has a
slope of
3/2?
Answer:
y=[tex]\frac{3}{2}[/tex]x-1
Step-by-step explanation:
y=mx+b
-7=[tex]\frac{3}{2}[/tex](-4)+b
-7=(-6)+b
b=(-1)
y=[tex]\frac{3}{2}[/tex]x-1
The graph of a polynomial function is shown. Which statement about the polynomial is true?
Answer:
The degree is odd and the leading coefficient is positive.
Step-by-step explanation:
Clearly from the graph of the polynomial function we see that both the ends of the graph are in the opposite directions.
This means that the degree of the polynomial is odd.
( Since in even degree polynomial both the ends are in the same direction )
Also, the leading coefficient of the polynomial is positive.
Since, when a leading coefficient of a odd degree polynomial let p(x) is positive then it satisfies the following property:
when x → -∞ p(x) → -∞
and when x → ∞ p(x) → ∞

Given a set of data, what steps would you take to identify whether the data showed linear or exponential growth?
Answer:
See explanation
Step-by-step explanation:
The first thing to do when given a data set is to ensure that the x-values are spaced in equal intervals.
The next is now to determine if the given y-values are increasing by the same amount(a common difference) or by the same ratio(a common ratio).
The data set is linear if the y-values increase by a common difference and the data set is exponential if the y-values increase by a ratio or factor.
Answer:
Which of the following steps did you include? Check all of the boxes that apply.
Make sure that the x-values are spaced apart in equal intervals.
Determine whether the y-values increase by the same amount or by the same ratio.
Decide that the data is linear because the y-values increase by a common difference.
Decide that the data is exponential because the y-values increase by a ratio or factor.

If 0 < z ≤ 90 and sin(9z − 1) = cos(6z + 1), What is the value of z?
Answer:
6Step-by-step explanation:
Given the expression sin(9z − 1) = cos(6z + 1), for 0 < z ≤ 90, we are to find z
Note that sin theta = cos(90-thetsa)
sin(9z − 1) = cos(6z + 1)
cos (90 - (9z-1)) = cos(6z + 1)
cos (90 - 9z+1)) = cos(6z + 1)
cos (91-9z) = cos(6z + 1)
Cos will cancel out to have;
91-9z = 6z+1
-9z - 6z = 1-91
-15z = -90
z = 90/15
z = 6
Hence the value of z is 6

A number cube is rolled 3 times. What is the probability that a number greater than 4 is rolled
all three times?
the probability of getting one is 1/6, and 2 is the same, 1/6. the probability of getting a number higher than 4 is 1/3. 1/6 * 1/6 * 1/3 = 1/108

There are equal numbers of men and women registered to vote. And the percent turnout was the same.
What proportion of men in the total electorate voted Yellow?
Answer:
Step-by-step explanation:
Answer:
n the immediate aftermath of a national election, exit polls offer the best glimpse of what the electorate looked like – who voted for whom and what seemed to drive their choices.
Traditionally, the exit polls have been a collaborative effort of a consortium of major media organizations, involving interviews with a representative sample of thousands of voters as they leave polling places across the nation. In this election, concerns about the pandemic helped drive an unprecedented number of Americans to vote early or by mail. By Nov. 3, more than 100 million Americans had already voted. To account for these voters, this year’s exit polls include data from telephone interviews with a representative sample of people who voted early or by mail. In all, the national exit poll includes interviews with 15,590 voters. It is important to note that these data will be updated, so the numbers below should be considered preliminary, reflecting the exit polls reported as of Nov. 4.

Answer:
1. m<T =72 , m<U =54
2. EF= 18 in. , m<F=134'
3. x=4
Step-by-step explanation:
1. <s=<u , there is 180' in a triangle total so 180- <S - <U = <T
180 - 54 - 54 = 72
2. ef = gf
180 - 23 - 23 = 134

ok answer this, 7x150+10 and that should be your answer.
Answer:
x=20
Step-by-step explanation:
there are two intersecting lines with two pairs of opposite angles each of the pairs are called vertical angles and if two angles are vertical, they are congruent
we know the angles are congruent, we also know (150=7x+10) and in order to solve for x we have to isolate x by subtracting 10 to both sides giving us (140=7x )
divide by seven on both sides to isolate x and that will give you x=20.
hope this helps :) have a nice day !!
