385 Students go on a field trip. There are 19 vehicles, some vans and some buses.
7 students can fit in a van, and 25 students can fit in a bus.
how many vans and buses were there ?
Answer:
14 buses and 5 vansStep-by-step explanation:
Let the number of buses be x and vans be y.
Equations as per given:
x + y = 1925x + 7y = 385Substitute y and solve for x the second equation:
y = 19 - x25x + 7(19 - x) = 38525x - 7x + 133 = 38518x = 385 - 13318x = 252x = 252/18x = 14Then finding y:
y = 19 - 14 = 5The answer is 14 buses and 5 vans

• In Mathematics, rectangle and square are both four sided polygon, having all the internal angles equal to 90.The opposite sides of the rectangle are equal in length whereas in square all the sides are same which makes rectangle different from square.
• Area of rectangle is the product of length and breadth of rectangle. Perimeter of rectangle is twice the sum of its length and breadth. Area of square is side * side and perimeter of square is 4* side.
• Area of rectangle = l*b
Perimeter of rectangle = 2(l+b)
• Area of square = side * side
Perimeter of square = 4 * side
We are given that perimeter of square and rectangle is same and the side of square is 4x-1 and length of rectangle is 2x+2 and width of rectangle is 2x.
Perimeter of Square = Perimeter of rectangle
4 * (4x-1) = 2(4x+2)
16x -4 = 8x + 4
8x = 8
x = 1
The value of x is 1
Side of square = 4 – 1 = 3
Length of rectangle = 4
Breadth of rectangle = 2

5+3w+3-w combine like terms to simplify
Answer:
8 + 2w
Step-by-step explanation:
⇒ Change all signs to addition (subtraction is the same as adding a negative):
5 + 3w + 3 + -w
⇒ Since the expression is now all addition, you can rearrange them in any order. So group the terms together by their type:
5 + 3 + 3w + -w
⇒ Simplify:
8 + 2w
Answer: 8 + 2w

Let the number of times he visits the gym be represented as x
A health club down the street has an initial joining fee of $100, and then you pay $5 each time you visit the gym. If Calvin spends $195,
The Amount he spends = $195
= $100 + $5 × x
$195 = $100 + 5x
5x = $195 - $100
5x = $95
x = 95/5
x = 19 times
Therefore, the number of times he visited the gym is 19 times.

Answer:
Because AC = BC
=> ️ACB is a isosceles triangle at C
=> m<A = m<B = 71°
At triangle ABC
m<A + m<B + m<ACB = 180°
=> 71° + 71° + m<ACB = 180°
=> m<ACB = 38°
We have m<ACB and m<ECD are 2 opposite angle
=> m<ECD = m<ACB = 38°
At triangle ECD
m<ECD + m<E + m<D = 180°
=> 38° + 90° + m<D = 180°
=> m<D = 52°

Which of the following values does not satisfy the inequality X - 7 > 12?
A 11
B 33
C 22
D 44
Answer:
We conclude that when we put x = 11, it does not satisfy the inequality.
Hence, option (A) is correct.
Step-by-step explanation:
Given the inequality
x - 7 > 12
Any value which makes the inequality FALSE would be the value that not satisfy the inequality.
Putting x = 11 in the inequality
x - 7 > 12
11 - 7 > 12
4 > 12
FALSE!
Reason: 4 can not be greater than 12
Putting x = 33 in the inequality
x - 7 > 12
33 - 7 > 12
26 > 12
TRUE!
Reason: 26 is indeed greater than 12
Putting x = 22 in the inequality
x - 7 > 12
22 - 7 > 12
15 > 12
TRUE!
Reason: 15 is indeed greater than 12
Putting x = 44 in the inequality
x - 7 > 12
44 - 7 > 12
37 > 12
TRUE!
Reason: 37 is indeed greater than 12
Therefore, we conclude that when we put x = 11, it does not satisfy the inequality.
Hence, option (A) is correct.

Add to simplify:
5n + 11n ⇒ equals 16n
So, the final answer is:
16n = 16n ⇒ True (16n does equal 16n)

A toy rocket is launched from a platform 4.9 meters above the ground in such a way that its height, h (in meters) after t seconds is given by the equation H= -4.9t^2+ 33.6t+ 4.9. How long will it take for the rocket to hit the ground?A toy rocket is launched from a platform meters above the ground in such a way that its height, h (in meters) after t seconds is given by the equation . How long will it take for the rocket to hit the ground?
Answer:
So H have to equale to 0
and [tex]t> 0[/tex]
[tex]-4,9t^2+33,6t+4,9=0\\\Delta=33,6^2+4*4,9*4,9=1225\\\sqrt{\Delta }=35\\t=\frac{-33,6-35}{2*(-4,9)} =14s[/tex]
Step-by-step explanation:
The toy rocket will take a time of 6.8571 seconds to hit the ground.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
Given that the height of the rocket (h), in meters, in terms of time (t), in seconds, is defined by a quadratic equation.
To determine the time needed for the rocket to hit the ground, that is, a time t greater than zero such that the height is zero. Now we proceed to solve the polynomial:
- 4.9 · t² + 33.6 · t + 4.9= 0
- 4.9 · (t² - 6.8571 · t - 1) = 0
- 4.9 · (t - 6.8571 ) · (t + 6.8571 ) = 0
Hence, the toy rocket will take a time of 6.8571 seconds to hit the ground.

Step-by-step explanation:
syukrwdgiiyredghjjrwwxvko8wasc9eyp
Answer:
92
Step-by-step explanation:
Angle (x+1) is equal to 92 degrees, and x equals 91. If x equals 91, then (x+1) equals 92. (x+1) and angle y are equal angles, so therefore, you can determine that angle y is equal to 92 degrees.

Given that g(x) = −2x+20, find g(−3).
Answer: 26
Step-by-step explanation:
Okay, so... The new equation would be -2(-3)+20...
So follow the rule of PEMDAS, PEMDAS is;
Parentheses
Exponents
Multiplication
Division
Adding
and Subtracting
Since there are no equations in parentheses and no exponents, we start with multiplication. Which would be -2(-3). ANY parenthesized number beside another number means you must multiply them.
-2(-3) = 6 because a negative multiplied by a negative is a positive..
Now we have 6 + 20 which is 26, so 26 is your answer.

280 ml as a percentage of 140 l.
Answer:
280 ml as a percentage of 140 l is 0.2%
Step-by-step explanation:
Note that 1 liter = 1000 millilitersTo find a percentage of a number divide the number by the total and multiply the quotient by 100%∵ There is an amount of 280 ml
∵ The total amount is 140 l
→ Change the liter to milliliters using the 1st point above
∴ 140 l = 140 × 1000 = 140000 ml
∴ 140 l = 140,000 ml
→ Now divide the amount by the total, then multiply the quotient by 100%
∵ 280 ÷ 140,000 = [tex]\frac{1}{500}[/tex]
∵ [tex]\frac{1}{500}[/tex] × 100% = 0.2%
∴ 280 ml as a percentage of 140 l is 0.2%
