Answer:
23.7
Step-by-step explanation:
Multiply 2.37 by 10
Answer:
$23.70
Step-by-step explanation:
3 toy cars
Each cost $2.37
How much does 30 toy cars cost
________________________________
We know that 3 toy cars cost 2 dollars and 37 cents. To solve, we first need to find what times 3 gets us 30.
3 * ? = 30
30 / 3
10
Therefore you need to multiply the amount of toy cars by 10 to get thirty toy cars, since three of them cost 2.37, multiply 10 by 2.37.
$2.37 * 10
$23.70

Select the correct answer.
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

6√3
Step-by-step explanation:
6 is x. side across from right angle (12) is 2x. so 6x2 to get 12. missing side is x√3. so 6√3
Answer:
6√3
Step-by-step explanation:
using the pythagorean theorem you can plug in the numbers to get √(12^2 - 6^2) = √(144-36) = √108 = 6√3.
The graph of y = f(x) is shown.
a) Find f(0)
4-
3.
b) Give the roots of f(x) = 0
Answer:
f(0) = 2
Roots are;
-2 and -1
Step-by-step explanation:
F(0) simply refers to the y-values when x = 0
This is the point at which the graph crosses the y-axis
the value here is 2
To
find the roots of f(x) , we simply find the points at which the plot crosses the x-axis
we have this at x = -2 and x = -1
These are what represents the roots of the equation

3 × (c2 − 8) for c = 3
Answer:
I am assuming c2, is c^2.
3 × (c2 − 8)
=3 ×(3^2-8)
=27-8
=19
If c2 is c*2
Then,
3 × (c2 − 8)
=3×(6-8)
=18-24
=(-6)

Answer:
y = √(3² + 3²)
9 = √(5² + x²)
Step-by-step explanation:
Diagram 1:
Hypotenuse = y
Opposite = 3
Adjacent = 3
y² = 3² + 3²
y = √(3² + 3²)
y = √(9 + 9)
y = √18
Diagram 2:
Hypotenuse ² = known leg² + unknown leg²
Hypotenuse = 9
Known leg = 5
Unknown leg = x
9² = 5² + x²
9 = √(5² + x²)
9² = 5² + x²
9² - 5² = x²
x² = 81 - 25
x = √ 56
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
Is Figure A congruent to Figure B? Explain.
No, because the orientation of Figure B is not the same as Figure A.
Yes, because Figure B can be obtained from Figure A by a series of translations.
Yes, because Figure B can be obtained from Figure A by a rotation and a translation.
No, because there is no sequence of translations, rotations, and reflections by which Figure B can be obtained from Figure A.

negitive 17plus n over 5 =33 what is n
Answer:
250
Step-by-step explanation:
-17+n/5=33
n/5=33-(-17)
n/5=33+17
n/5=50
n=50*5
n=250
n=182
Step by Step Explanation:
The equation we would start out with is:
[tex] \frac{ - 17 + n}{5} = 33[/tex]
From here, we need to multiply both sides by 5. This would create an equation of -17+n=165, as we canceled out the 5.
Then, you need to add 17 to both sides to isolate the variable. This would make the equation n=182, our final answer.

Answer:
1/4x function A vs 0.75x function B lastly 0.25 is less than 0.75 Give brainlistOur 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.

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:
100m
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
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]

Robert's new hybrid car has a gas tank that holds 12 gallons of gas. When the tank is full, they can drive 420 miles. Assume that their car uses gas at a steady rate.
a. What is the unit rate:
b. Write the equation:
c. Use your equation to find out how many gallons of gas Robert will need to drive 287 miles. 287miles =
gallons of gas
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
