The cost of a daily rental car is as follows: The initial fee is $69.99 for the car, and it costs $0.30 per mile. If John initially pays $200.00 before taxes and does not want to exceed that amount, how many miles can he drive?
x ≥ 433 miles
x = 450 miles
x ≥ 450 miles
x ≤ 433 miles
x [tex]\geq[/tex] 433
explanation:
let m equal miles
0.30m + 69.99 = 200
-69.99 -69.99
0.30m = 130. 01
130.01 / 0.30 = 433. 36...
but we're gonna round it to 433
so 433 miles

Answer:
12.6
Step-by-step explanation:
Given
with reference angle 57°
perpendicular (p) = y
hypotenuse (h) = 15
Now
sin 57° = p / h
0.84 = y / 15
y = 0.84 * 15
y = 12.6

Proving triangle similarity given QR PT and QPR STR prove PQR TSR
The triangles are right triangles, then we can apply Pytagoras´ theorem.
Solution is:
The triangles are similar
From the attached picture, and from parameterization concepts
RS = μ × RQ 0 < μ < 1
From Δ PRQ sinα = RQ/PR PQ = h₁ ( hypothenuse in Δ PRQ)
From Δ RST sinα = RS/ST ST = h₂ ( hypothenuse in Δ RST)
Then RQ/h₁ = RS/h₂
or RQ × h₂ = RS × h₁ ⇒ h₂ = (RS/RQ) × h₁ ⇒ h₂ = μ × h₁
Then both hypothenuse are proportional, it follows both triangles are similar

Answer:
x=-1/20
Step-by-step explanation:
7/2x+1/2x=10+9/2x
We move all terms to the left:
7/2x+1/2x-(10+9/2x)=0
Domain of the equation: 2x!=0
x!=0/2
x!=0
x∈R
Domain of the equation: 2x)!=0
x!=0/1
x!=0
x∈R
We add all the numbers together, and all the variables
7/2x+1/2x-(9/2x+10)=0
We get rid of parentheses
7/2x+1/2x-9/2x-10=0
We multiply all the terms by the denominator
-10*2x+7+1-9=0
We add all the numbers together, and all the variables
-10*2x-1=0
Wy multiply elements
-20x-1=0
We move all terms containing x to the left, all other terms to the right
-20x=1
x=1/-20
x=-1/20

find the measure of the missing angles
Answer:
b=80
c=80
Step-by-step explanation:
the angle opposite to the 100 degree angle is congruent to it
same goes for b and c
so far we have 2 angles that measure 100 degrees 100+100=200
the sum of the 4 angles is 360
360-200=160
160/2=80=b=c

The circumference of a circle is 9.37cm.
Find the length of the diameter.
Give your answer rounded to 2 DP
Answer:
9.37 divide by two = 4.685
4.685 in 2DP = 4.68
Step-by-step explanation:
i hoped this helps.
Answer:
2.98 :)
Step-by-step explanation:
the circumference is when you do pi times diameter.
do 9.37 divided by 3.14(pi) to work out the diameter.
9.37/3.14=2.984
rounded its 2.98
Select all equations that have graphs with the same y-intercept.
y = 3x - 8
y = 3x - 9
y = 3x + 8
y = 5x - 8
y = 2x - 8
y = (1/3)x - 8
The equations that have graphs with the same y-intercept are:
y = 3x - 8y = 5x - 8y = 2x - 8y = (1/3)x - 8To determine which equations have graphs with the same y-intercept, we need to look for equations that have the same constant term when written in the form y = mx + b, where m represents the slope and b represents the y-intercept.
The y-intercept is the value of y when x is equal to 0. In other words, it is the point where the graph intersects the y-axis.
Let's compare the equations and their constant terms:
y = 3x - 8 (Constant term: -8)
y = 3x - 9 (Constant term: -9)
y = 3x + 8 (Constant term: 8)
y = 5x - 8 (Constant term: -8)
y = 2x - 8 (Constant term: -8)
y = (1/3)x - 8 (Constant term: -8)
From the comparison, we can see that the equations y = 3x - 8, y = 5x - 8, y = 2x - 8, and y = (1/3)x - 8 all have the same constant term of -8. This means that their graphs will have the same y-intercept, which is -8.
Therefore, the equations that have graphs with the same y-intercept are:
y = 3x - 8
y = 5x - 8
y = 2x - 8
y = (1/3)x - 8
