5
of the total distance. If Charlie drove the rest of the distance, how many miles did Charlie drive?
The distance droved by Charlie is about 38 miles
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
The distance between San Antonio and Houston is 190 miles. Nicholas and Rose each drove 2/5 of the total distance.
Distance droved by Nicholas = Distance droved by rose = (2/5) * 190 = 76 miles
Distance droved by Charlie = 190 - 76 - 76 = 38 miles
The distance droved by Charlie is about 38 miles

You would like to purchase the car in 2 years. How much money will you need to invest at a 3.3% interest rate compounded annually in order to have $9500 in 2 years? Use the compound interest formula A = P (1 + i)n. (Round final answer to the nearest cent, but otherwise don’t round any intermediate values)
Answer:
$ 8902.72
Step-by-step explanation:
We would like to calculate the money which we need to invest at 3.3% rate compounded annually for two years . We know that ,
[tex]\longrightarrow \boldsymbol{ A = P \bigg(1+\dfrac{R}{100}\bigg)^n } [/tex]
where the symbols have their usual meaning . So here ,
Amount = $ 9500 time = 2 years Rate = 3.3% P = The money we need to invest (?)[tex]\longrightarrow \$ 9500 = P \bigg( 1+\dfrac{3.3}{100}\bigg)^2\\ [/tex]
Simplify RHS ,
[tex]\longrightarrow \$ 9500 = P \bigg(\dfrac{100+3.3}{100}\bigg)^2\\[/tex]
Simplify Nr . in RHS ,
[tex]\longrightarrow \$ 9500 =P\bigg(\dfrac{103.3}{100}\bigg)^2\\ [/tex]
Isolate P ,
[tex]\longrightarrow P = \dfrac{ \$9500\times 100\times 100}{103.3\times 103.3}\\[/tex]
Simplify ,
[tex]\longrightarrow \underline{\underline{\boldsymbol{ P = \$ 8902.72 }}}{} [/tex]
And we are done !
[tex]\bold{Formula: A = P(1 + \frac{r}{100})^{(n)}}[/tex]
Where
A = AmountP = PrincipalR = RateN = time compounded[tex] \bold{Solution : } \\ \\ \: \: \: \: \tt \: A = 9,500(1+\frac{3.3\%}{100})^{(2)} \\ \: \: \: \: \: \: \tt \: A = 9,500(1+ 0.033)^{(2)} \\ \tt \: A = 9,500(1.033)^{(2)} \: \: \\ \tt \: A = 10,137.34 \qquad \: \: \: [/tex]
therefore,I need $10,137.34 if would like to purchase the car.

Answer:
£ 45.6
Step-by-step explanation:
Number of adults ⇒ 12
Number of children ⇒ 26
Total cost of tickets ⇒ £ 1804.80
Cost of an adult's ticket ⇒ £ 51.60
Cost of a ticket for child ⇒ ?
Let the cost of a ticket for child be x.
Therefore,
Total cost = cost of tickets for adults + cost of tickets for children
Total cost = (No. children × Cost of a ticket) + (No.adults × Cost of a ticket)
£ 1804.80 = 26x + 12 × £51.60
1804.80 = 26x + 619.2
1804.80 - 619.2 = 26x
1185.6 = 26x
Divide both sides by 26.
45.6 = x
So,
Cost of a ticket for child is £45.6
Step-by-step explanation:
12 x 51.60 you get the total cost for the adult tickets and all thats left is the total cost - adult ticket cost and then you get the child ticket wirth now all thats left is childs ticket cost % 26

(8x + 7)
5yº
(7y -- 34)
= (2x - 4)^
Answer:
x = 11
y = 17
Step-by-step explanation:
We know that opposite angles (or vertical angles) are equal.
So
8x + 7 = 9x - 4
Subtract 8x from both sides of the equation
8x - 8x + 7 = 9x - 8x - 4
7 = x - 4
Add 4 to both sides of the equation
7 + 4 = x - 4 + 4
11 = x
Looking at the other 2 angles,
5y = 7y - 34
Subtract 7 y from both sides of the equation
5y - 7y = 7y - 7y - 34
-2y = -34
Divide both sides by -2
-2y/-2 = -34/-2
y = 17
Answer:
Step-by-step explanation:
Vertically opposite angles are equal.
8x + 7 = 9x - 4 {Add 4 to both sides}
8x + 7 + 4 = 9x
8x + 11 = 9x {Subtract 8x from both sides}
11 = 9x - 8x
x = 11
7y - 34 = 5y {Add 34 to both sides}
7y = 5y + 34 {Subtract 5y form both sides}
7y - 5y = 34
2y = 34 {Divide both sides by 2
y = 34/2
y =17
I bought a sweater for 25% off and paid $30. What was the *original* price? Please explain.
well, the original price was "x", which oddly enough is the 100%, we also know that 25% off that is 30 bucks, so namely 100% - 25% = 75%, is 30 bucks, so
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 30&75 \end{array}\implies \cfrac{x}{30}=\cfrac{100}{75}\implies \cfrac{x}{30}=\cfrac{4}{3} \\\\\\ 3x=120\implies x=\cfrac{120}{3}\implies x=40[/tex]

Write the point-slope form of the equation of the line that passes through the point (-1,5) and has a slope of -1. Include
your work in your final answer. Type your answer in the box provided to submit your solution.
Answer:
y= - x + 4
Step-by-step explanation:
The point-slope form of the equation of a line is:
y= m ( x - h )+ k
Where m is the slope and (h,k) is a point through which the line passes.
The slope of the line is m=-1 and it passes through (-1,5), thus the equation of the line is:
y=(-1) ( x - (-1) ) + 5
Operating:
y= - ( x + 1 ) + 5
y= - x - 1 + 5
Simplifying:
y= - x + 4

Mangojuicecosts$8.50perquartandbananajuicecosts$6.20perquart.Tyler wants to make a mixture of mange and banana juice that sells for $5.50 per quart. How many quarts "q" of mango juice should he mix with 4 quarts of banana juice to make mango-banana juice at that price? Which equation below represents the situation?
Answer:
There is no possible combination that will result in mango-banana juice that costs $5.50 per quart if its two ingredients cost $8.50 and $6.20 per quart.
Step-by-step explanation:
the equation you need to solve is:
let M = quantity of mango juice
$8.50M + (4 x $6.20) = (4 x $5.50) + $5.50M
$8.50M + $24.80 = $22 + $5.50M
$24.80 - $22 = $5.50M - $8.50M
$2.80 = -$3M
M = $2.80 / -$3 = -0.933 ⇒ the quantity of mango juice cannot be negative

The height h (in feet) of an object dropped from a ledge after x seconds can be modeled by h(x)=−16x2+4. The object is dropped again from a different starting height so that it hits the ground 2 seconds later. Write a function g that models the path of the object the second time it is dropped.
Answer:
g(x) = - 16x² + 100
Step-by-step explanation:
Given the model:
First drop:
h(x) = - 16x² + 4
Second drop hits the ground 2 seconds later
Function g(x) to model the second drop:
-16t² + V0t + h0
h(x) = - 16x² + 4
0 = - 16x² + 4
16x² = 4
x² = 4/16
x² = 1/4
x = 1/2
2 seconds later :
X = 1/2 + 2
x = 2.5
0 = - 16(2.5)² + 0 + h0
0 = - 100 + h0
h0 = 100
Hence,
g(x) = - 16x² + 100

I need help ASAP
Answer:
x=33/5
Step-by-step explanation:
Let's solve your equation step-by-step.
2x+4/5 −6=8
Step 1: Simplify both sides of the equation.
2x+4/5−6=8
2x+4/5+−6=8
(2x)+(4/5+−6)=8(Combine Like Terms)
2x+−26/5=8
2x+−26/5=8
Step 2: Add 26/5 to both sides.
2x+−26/5+26/5=8+26/5
2x=66/5
Step 3: Divide both sides by 2.
2x/2=66/5/2
