A Rental Car Agency charges a flat fee of $25 per day plus $0.15 for each mile driven. The total charge for one day's rental was $75.30. Which equation below can be used to solve this problem?
Answer:
Step-by-step explanation:
75.30-25 for a day leaves 50.30 for mileage.
50.30/.15 per mile= 335.3 miles driven.
75.30>=25+0.15m. m=335.3

What is Pythagorean theorem?Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
Here, given that,
she leaves the health club and bikes 16 miles south.
Then, She then runs 12 miles west.
so, we have,
It must be, hypotenuse = 16 miles
base= 12 miles
We have to find, the height.
by Pythagorean theorem, we get,
the distance Jane's trainer bikes=√16²-12² miles
=√32 miles
=5.66 miles
So. she travels in total = 28 miles
22.34 miles much farther does Jane travel than her trainer.

Translate the sentence into an inequality..
The quotient of y and 7 is at least 18.
Answer: [tex]\frac{y}{7} \geq 18[/tex]
Step-by-step explanation:
Key things to remember:
- quotient signals dividing
- at least means greater than or equal to, so we use the greater than or equal to sign
Applying this to the problem, we can translate into a simpler sentence:
y divided by 7 is greater than or equal to 18 --> which leads us to the inequality above
A farmer grows a particular plant that has a gene that can be manipulated to control the age t at which the plant matures. The number of seeds S(t) produced by a plant maturing at age t is S(t)=−0.3t2+30t+0.2 seeds per mature plant A farmer asks the geneticists to genetically engineer a plant line that accounts for the fact that on his farm, only P(t)=90000t+100, plants mature to age t. What age of maturity should the geneticist select for the plants to maximize the seed production of the farmer's crop?a. Between 130 and 140 days b. Between 120 and 130 days
Answer:
The correct option is;
Between 40 and 50 days
Step-by-step explanation:
The number of seeds that are produced by a plant maturing at age t, S(t), is given as follows;
S(t) = -0.3·t² + 30·t + 0.2
The proportion of plants maturing at age (t) in the plants to be engineered by the geneticist P(t) = 90000/(t + 100)
The number of seeds produced by the plants = S(t) × P(t) = (-0.3·t² + 30·t + 0.2)×(90000/(t + 100))
To find the maximum number of seeds, we differentiate using an online tool, and equate to zero to get;
d((-0.3·t² + 30·t + 0.2)×(90000/(t + 100)))/dt = (-27000·t² - 5400000·t + 269982000)/(t + 100)² = 0
(-27000·t² - 5400000·t + 269982000)/(t + 100)² = 27000(t - 41.419)(t + 241.419)/(t + 100)² = 0
t = 41.419 or t = -241.419
Therefore, in order to maximize the production of seed of the crops of the farmer, the geneticist should select between 40 and 50 days.

The formula for the area of a triangle is A =12bh, in which b represents the length of the base and h represents the height. If a triangle has an area of 232 mm 2 and the height is 16 mm, what is the measure of the base? The measure of the base is mm.
Answer:
Step-by-step explanation:
Write it out: A = 1/2(bh)
substitute values: 232 = 1/2(16b)
Simplify: 232 = 8b
Divide each side by 8: b = 29
The base is 29 millimeters

Answer:

Step-by-step explanation
The length of the park has been cut off in the question but if it is one mile, like I think it is, then this is the answer.
A = 2/3
A = L x W
2/3 = 1 X ?
? = 2/3
Answer:
width = 2/3 mile
Step-by-step explanation:
area = L * W
where area = 2/3 mile²
length = 1 mile
width = ?
2/3 = 1 (W)
2 = 3W
W = 2/3 mile
therefore the width = 2/3 mile
length = 1 mile

Answer:
2(3 + w) = 6 + 2w
2(1 + w) = 2 + 2w
3(2 + w) = 6 + 3w
6(1 + w) = 6 + 6w
Step-by-step explanation:
2 x 3 = 6 and 2 x w = 2w: Therefore your answer is 6 + 2w
2 x 1 = 2 and 2 x w = 2w: Therefore your answer is 2 + 2w
3 x 2 = 6 and 3 x w = 3w: Therefore your answer is 6 + 3w
6 x 1 = 6 and 6 x w = 6w: Therefore your answer is 6 + 6w
what’s the slope of (9,3) and (2,11)
Answer:
slope = - [tex]\frac{8}{7}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (9, 3) and (x₂, y₂ ) = (2, 11)
m = [tex]\frac{11-3}{2-9}[/tex] = [tex]\frac{8}{-7}[/tex] = - [tex]\frac{8}{7}[/tex]
Answer:
[tex]\boxed {m = -\frac{8}{7}}[/tex]
Step-by-step explanation:
Use the Slope Formula to help you determine the slope of two given points:
[tex]m =\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
First point: [tex](x_{1}, y_{1})[/tex]
Second point: [tex](x_{2}, y_{2})[/tex]
-Apply the two given points onto the formula:
First point: [tex](9, 3)[/tex]
Second point: [tex](2, 11)[/tex]
[tex]m =\frac{11 - 3}{2 - 9}[/tex]
-Solve for the slope:
[tex]m =\frac{11 - 3}{2 - 9}[/tex]
[tex]m =\frac{8}{-7}[/tex]
[tex]\boxed {m = -\frac{8}{7}}[/tex]
Therefore, the slope is [tex]-\frac{8}{7}[/tex].

Q's Asked: Which of the following options is an equivalent function to f(x) = 4(3)2x?
Possible answers:
f(x) = 36^x
f(x) = 4(9)^x
f(x) = 144^x
f(x) = 4(6x)
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
My answer: I Think the correct answer is (B) .The reason why I think the answer is (b) is bc:
[tex]f(x) = 4(3)^{2x}[/tex] =36
Calculations on How I got 36.
Frist we calculate the exponents [tex]\left(3\right)^2[/tex] --> [tex]\left(3\right)^2=9[/tex]---> =9
then we Multiply 4*9 which gives us : 36.
The reason why Its (B) is bc:
f(x) = 4(9)^x
which means 4 times nine is...... 36. thats the answer (B) f(x) = 4(9)^xHope this helps :3

What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Δ ABC ≅ Δ DEF
And, m ∠A = (x + 30)°, m ∠C = 45°, and m ∠D = 80°
Now,
Since, Δ ABC ≅ Δ DEF
Hence, m ∠A = m ∠D
Substitute all the values, we get;
m ∠A = m ∠D
x + 30 = 80
Subtract 30 both side, we get;
x = 80 - 30
x = 50°
Thus, The measure of ∠A will be 50°.

I have to have 20 characters or more to be able to ask the question....
Answer:
m<QRS=48°
m<RSQ=69°
m<RQS=63°
Step-by-step explanation:
Since we know that the measures of the angles of any triangle is 180°, we can form this equation: 7a-1+10a-1+9a=180°
Then, we can use simple algebra to solve for a and plug in that value into the equations that the degrees represent to get our angle measures.
7a-1+10a-1+9a=180°
26a-2=180°
26a=182°
a=7
Now, plug in that value of a and you have your anlage measures!! Hope this helps!! :)
