Answer:
sorry i only know the answer of c
it's 8.2 gallons
Step-by-step explanation:
12 gallons = 420 miles
12 gallons = 420 miles? gallons =287 miles
420 miles ÷ 12 gallons = 35miles/gallon
420 miles ÷ 12 gallons = 35miles/gallon287 miles ÷ 35 miles/gallon = 8.2 gallons
Answer:
Step-by-step explanation:
Unit rate = (420 miles)/(12 gallons) = (420/12 miles)/gallon = (35 miles)/gallon
:::::
Fuel consumption = (number of miles) × (1 gallon)/(35 miles)
:::::
287 miles × (1 gallon)/(35 miles) = 8.2 gallons

Alice drew a rectangle with a perimeter of 30 cm and an area of 56 cm2. Which dimensions match Alice's rectangle?
Answer:
The dimensions that match Alice's rectangle are 7 cm and 8 cm.
Step-by-step explanation:
The perimeter of the rectangle is given by:
[tex] P = 2(a + b) = 30 cm [/tex] (1)
Where a and b are the sides of the rectangle
Also, the area of the rectangle is:
[tex] A = a\times b = 56 cm^{2} [/tex] (2)
By solving equation (1) for a, we have:
[tex] a = 15 cm - b [/tex] (3)
Now, by entering equation (3) into (2) we can find one side of the rectangle:
[tex] 56 cm^{2} = (15 cm - b)\times b [/tex]
[tex] b^{2} - 15b + 56 = 0 [/tex]
Solving the above quadratic equation we have:
b₁ = 7 cm and b₂ = 8 cm
Now, the other side of the rectangle can be calculated with equation (3):
[tex] a = 15 cm - b_{1} = 15 - 7 cm = 8 cm [/tex]
or
[tex] a = 15 cm - b_{2} = 15 - 8 cm = 7 cm [/tex]
Taking the first solution (b₁) or the second (b₂), we find that the dimensions that match Alice's rectangle are 7 cm and 8 cm.
Therefore, the dimensions that match Alice's rectangle are 7 cm and 8 cm.

6. Mary flips the coin and then she spins the spinner. What is the
probability that the coin will not land on tails, and the spinner will not land
on 3? Spinner (1, 2, 3, 4); Coin (H, T) *
A 1/8
B 1/4
C 3/8
D 1/2
Answer: For the coin, there are 2 possibilities which are Heads and Tails so the possibility is 1/2 and for the spinner it will be 1/4 because there are 4 possibilities.

D. y=3x+2
7-3y=34
What's y??
Plzzz help due today!!
Answer:
y = -9 (negative 9)
Step-by-step explanation:
7 - 3(-9) =
7 - (-27) =
34
Hope this helped and pls mark brainliest!
Answer:
y = -9Explanation:
7 - 3y = 34
Simplify both sides of the equation
7 − 3y = 34
7 + −3y = 34
−3y + 7 = 34
Subtract 7 from both sides
−3y + 7 − 7 = 34 − 7
−3y = 27
Divide both sides by -3
−3y / -3 = 27 / -3
Simplify
y = -9

Our principal has to travel from one city to the next city at an average speed of 50km/hr. Compute for the distance between 2 cities
Answer:
The answer is false or "impossible"
Step-by-step explanation:
Heres why I say this:
If the “average speed” in one hour make the car travel 50km, it means the speed could not be constant. So, it could be 90km/h during the first 30 minutes and 10km/h during the second 30 minutes. If this is the case, for example, in the next 12 minutes after the first hour, the car could be traveled 18km at 90km/h, completing 50 + 18 = 68km. The tricky word “average” makes it impossible to answer. Good try, but no cigar.
Car Survey In a survey of 2,000 people who owned a certain type of car, 1,400 said they would
buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
70%
Step-by-step explanation:
1. 1400÷2000 = 0.07
2. move the decimal over 2 spaces for a percentage 0.07 --> 70.0
3. 70.0 = 70%

Katy inherited a savings account that was started by her grandfather 20 years ago. His investment can be modeled by the function
A(t) = 10,000(1.012)^t+ 20, where A(t) represents the value of the account, in dollars, t years after the inheritance. Which function is
equivalent to A(t)?
A)
A(t) = 10,000(1.012)^20
B)
A(t) = 10,000[(1.012)^t]^20
C)
A(t) = 10,000(1.012)^t (1.012)^20
D)
A(t) = 10,000[(1.012)^t + (1.012)^20]

Answer:
D
Step-by-step explanation:
We are combining like terms So,
Step 1
-5x + 2y + 3x
Step 2
-5x + 2y + 3x combine like terms
(-5x+3x)+(2y) Then you simplify
-2x+2y
So therefore, your answer is D

Which expression is equivalent to x + y+ x + y +30+5)?
A. 2x + 5y+ 5
B. 2x + y + 30
C. 2x + 5y + 15
D.2x + 3y + 10
Answer:
Step-by-step explanation:
Like terms have same variable with same exponent. Combine the like terms.
x + x = 2x {Just add the coefficient}
x + y + x +y + 30 + 5 = x +x + y + y + 30 + 5
= 2x + 2y + 35

a taxi service charges $2.40 for the first mile of a ride and $1.40 for every additional mile. linda planned to give a $2 tip for the taxi driver. how many miles can she ride for $10?
Answer:
5 miles
Step-by-step explanation:
2 as a baseline then add 2.40 for first mile which then comes up to 4.40. 4.40 plus 1.40 = 5.80 plus 1.40 = 7.20 plus 1.40 = 8.60 plus 1.40 = 10. then we count the amount of 1.40's we added which was 4. and then we account for the first mile so there we have 5 miles
Answer:
5 miles
Step-by-step explanation:
What is the value of x in the diagram?
(x + 45)
(x + 105)
if the addition if (X+45)° and (X+105)° equal 180°
due to they are a co- interior angles.
then X+45+X+105 = 180°
2X+150 = 180°
2X = 30
X = 15°

You ride your bicycle along the outer edge of the park. Then you take a shortcut back to where you started. Find the length of the shortcut. Round your answer to the nearest tenth.
Answers:

60m
116.6m
160m
Answer:
116.6
Step-by-step explanation:
Answer:
116.6
Step-by-step explanation:
To solve this equation you would need to use the pythagorean theorem. The pythagorean theorem is [tex]a^{2} +b^{2}= c^{2}[/tex] where a and b are lengths of the triangle and c is the hypotenuse (the longest side of a triangle) in this case, the short cut.
First, you would substitute values into the equation:
[tex]100^{2}+60^{2}= c^{2}[/tex]
Then, you would multiply out the squares:
[tex]10,000+3600=c^2[/tex]
Add the numbers together:
[tex]13600=c^2[/tex]
Take the square root of both sides to get the answer:
[tex]c=116.619037897[/tex]
Then round to the nearest tenth to get the answer: c=116.6
