On a map of Arizona, the scale is 1 inch = 5 inches. The distance between Brady's house and Flagstaff is 23 inches on the map. What is the actual distance between Brady's house and Flagstaff.
So we know that 1 inch on the map = 5 inches.
So if Brady's house is 23 inches away from Flagstaff on the map:
23 * 5 = 115.
So 115 inches is the actual distance...
Wait. His house is 9 feet away from Flagstaff? That's cool.

Which decimal is equivalent to 8%
Answer:
[tex]0.08[/tex]
Step-by-step explanation:
Given : 8%
To find the decimal value of the percentage number
Remove the percentage symbol with 100 in the denominator
gives
[tex]\frac{8}{100}\\[/tex]
Now taking the numerator to the decimal place equal to the number of zeros in the denominator or simply divide denominator with numerator.
Gives = [tex]0.08[/tex]
So, the decimal equivalent of the given value is [tex]0.08[/tex]
0.08
Step-by-step explanation:
8% can be written as 8/100 in the fractional form.
now when we will divide anything by 100, we will count the 0s in 100. here 2 zeros are there.
so we will put the decimal point before two digit. in numerator we already have 8.
we need another digit, so we put 0 then the decimal point.
that means 0.08

solve for p
4(p+2)=28
We can use the distributive property for this:
4 (p+2) = 28
4p + 8 = 28.
4p = 28 - 8.
4p = 24.
Divide by 4 on both sides:
p = 6

What kind of triangle is this?
Obtuse
Acute
Supplementary
Right
Please help!!!?!!
Option D:
Right triangle
Solution:
Let us first define obtuse, acute right triangle and supplementary.
Obtuse angled triangle:
If any one of the angle in the triangle is more than 90°, then the triangle is an obtuse angled triangle.
Acute angled triangle:
If all the angles of the triangle are less than 90°, then the triangle is an acute angled triangle.
Right angled triangle:
If any one of the angle in the triangle is exactly 90°, then the triangle is a right angled triangle.
Supplementary:
If sum of the angles is 180°, then the angles are supplementary angles.
But this is not a kind of triangle.
In given triangle one of the angle is 90°.
Therefore, this is a kind of right triangle.
Option D is the correct answer.

perpendicular from the point o(2, -3)
to the line y = 3x + 1.
(i) Find the length of DO.
(ii) Find the coordinates of the
reflection of A in the line y = 3x + 1
Answer:
(I) using the equation y=3x+1 at x=2 the length of Line DO is y=3(2)+1
Therefore y=7
(II) the coordinates At x=-3
Y=3(-3)+1=-8
Hence from (I) above also the coordinates are (7,-8)
Step-by-step explanation:
Step 1 :you declare variables
Step 2: you solve the equation at both points on the graph
What are the coordinates of the x-intercepts of the graph of y = (x - 3)(x + 2) ?

The coordinates of x-intercepts of the graph of y = (x - 3)(x + 2) are (3 , 0) and (-2 , 0) ⇒ 4th answer
Step-by-step explanation:
The x-intercepts of a quadratic function is the values of x when y equal to zero
If y = (x - a)(x + b), then to find x-intercepts do that:
Put y = 0Equate each bracket by zeroFind the two values of x ( x = a , x = -b)The x-intercepts are (a , 0) and (-6 , 0)∵ The equation of the graph is y = (x - 3)(x + 2)
- To find the x-intercepts equate y by 0
∴ (x - 3)(x + 2) = 0
- Equate each bracket by 0
∵ x - 3 = 0
- Add x to both sides
∴ x = 3
∵ x + 2 = 0
- Subtract 2 from both sides
∴ x = -2
∴ The graph intersects the x-axis at points (3 , 0) and (-2 , 0)
The coordinates of x-intercepts of the graph of y = (x - 3)(x + 2) are (3 , 0) and (-2 , 0)

The sum of two numbers is 90. The larger number 14 more than 3 times the smaller number. Find the numbers.
The numbers are 71 and 19
Solution:
Let "x" be the larger number
Let "y" be the smaller number
Given that,
Sum of two numbers is 90
Therefore,
x + y = 90 ------ eqn 1
The larger number 14 more than 3 times the smaller number
Larger number = 14 + 3(smaller number)
x = 14 + 3y ------ eqn 2
Let us solve eqn 1 and eqn 2
Substitute eqn 2 in eqn 1
14 + 3y + y = 90
14 + 4y = 90
4y = 90 - 14
4y = 76
Divide both sides by 4
y = 19
Substitute y = 19 in eqn 2
x = 14 + 3(19)
x = 14 + 57
x = 71
Thus the numbers are 71 and 19

3. The area of a rectangle is 45x^8y^9square yards. If the length of the rectangle is 5x^3y^4 yards,
which expression represents the width of the rectangle in yards?
Answer:
Answer:
The expression for the width of the rectangle is [tex]9x^{5}y^{5}[/tex].
Step-by-step explanation:
The formula to compute the area of a rectangle is,
[tex]Area=length\times width[/tex]
Given:
Area = [tex]45x^{8}y^{9}\ square\ yards[/tex]
Length = [tex]5x^{3}y^{4}\ yards[/tex]
Determine the expression for the width of the rectangle as follows:
[tex]Area=length\times width\\45x^{8}y^{9}=(5x^{3}y^{4})\times width\\width = \frac{45x^{8}y^{9}}{5x^{3}y^{4}} \\=\frac{45}{5}\times [x^{8-3}]\times [y^{9-4}]\\ =9x^{5}y^{5}[/tex]
Thus, the width is [tex]9x^{5}y^{5}[/tex].

Driving. In an emergency, the distance,
d m, it takes for a car moving at a
speed of v m/s to stop completely is
given by d = 0.15v2 + v.
(i) When the car has only 80 m to stop,
show that 3v2 + 20v – 1600 < 0.
(ii) Solve the inequality in part (i) to
find the maximum speed of the car.
Answer:
i) The proof is belowii) The maximum speed is 20m/s
Explanation:
(i) When the car has only 80 m to stop, show that [tex]3v^2+20v-1600<0.[/tex]
The distance, [tex]d[/tex] [tex]m[/tex], it takes for a car moving at a speed of [tex]v[/tex] [tex]m/s[/tex] to stop completely is given by [tex]d=0.15v^2+v[/tex]
The car must stop before the 80 m, so the distance to stop is less than 80 m:
[tex]d<80[/tex]
Substitute:[tex]0.15v^2+v<80[/tex]
Multiply both sides by 20:[tex]20\times 0.15v^2+20\times v<20\times 80\\\\3v^2+20v<1600[/tex]
Subtract 1600 from both sides:[tex]3v^2+20v-1600<0[/tex]
Which is the expression you wanted to prove.
(ii) Solve the inequality in part (i) to find the maximum speed of the car.
To solve the inequality you need to factor the left side:
Put 20v as 80v - 60v[tex]3v^2+80v-60v-1600<0[/tex]
Use commutative property of addition[tex]3v^2-60v+80v-1600<0[/tex]
Use associative property[tex](3v^2-60v)+(80v-1600)<0[/tex]
Factor each binomial:[tex]3v(v-20)+80(v-20)<0[/tex]
Common factor [tex](v-20)[/tex][tex](v-20)(3v+80)<0[/tex]
There are two possible solutions: 1) the first factor is positive and the second negative, and 2) the first factor is negative and the second positive.
1. First tentative solution
[tex]v-20>0\\\\v>20\\\\3v+80<0\\\\3v<-80\\\\ v<-80/3\\\\v<-26.26[/tex]
The speed cannot be greater than 20m/s and less than - 26.26 m/s at the same tine, thus, there are not solutions for this assumption.
2. Second tentative solution
[tex]v-20<0\\\\v<20\\\\3v+80>0\\\\3v>-80\\\\ v>-80/3\\\\v>-26.26[/tex]
You are looking for an upper bound, thus the solution is that the speed is less than 20m/s.
11. Ben is saving money to buy a TV that costs $495,
including tax. Ben opens a savings account with a
deposit of $75 and deposits $65 at the end of each
month. What is the minimum number of months Ben
will need to make deposits until he has enough money
in his account to buy the TV ? .
Answer:
7 months
Step-by-step explanation:
equation:
75+65x
75+65(6)=465 <495
75+65(7)=530>495
Ben will need to make deposits for at least 7 months to have enough money to buy the TV.
Explanation:To determine the minimum number of months Ben will need to make deposits until he has enough money to buy the TV, we can set up an equation.
First, subtract the initial deposit of $75 from the total cost of the TV ($495) to find out how much more money Ben needs: $495 - $75 = $420.Next, divide the remaining amount needed by the monthly deposit of $65: $420 ÷ $65 = 6.46.Since Ben cannot make a fraction of a month, we round up the decimal value to the nearest whole number. Therefore, Ben will need to make deposits for at least 7 months to have enough money to buy the TV.Learn more about determining the number of months needed to save for a purchase here:https://brainly.com/question/34732053

Which of the following sets of equations correctly represents this situation?
Answer:
Step-by-step explanation:
$8.75
Tyler gets $30 in change after buying a 7-day snowboarding ticket with a discount, having gone to the ticket counter with $340.
To calculate the change Tyler gets back, we must first determine the total cost of his 7-day snowboarding trip with the discount.
Tyler plans to snowboard for 7 days. A daily ticket costs $50. Since he is going to snowboard for 7 or more days, he gets a discount of $40 off the total.
Without the discount, the cost for 7 days would be 7 days * $50/day = $350.Applying the discount, the total cost becomes $350 - $40 = $310.Tyler goes to the ticket counter with $340. To find out how much change he gets back, we subtract the total cost from the amount he has:
$340 - $310 = $30
Therefore, Tyler will receive $30 in change.
