Answer:
12 classrooms
Step-by-step explanation:
We know that there are 3 math classrooms, and three math classrooms is 25% of all of the classrooms. We need to know the total number of classrooms, which is 100% of the classrooms, so we do 25% times 4. Because we did 25 times 4, we have to do 3 classrooms times 4, and we get 12 classrooms.
Here's a ratio explanation.:
Percent of classrooms : Classrooms
25 : 3
100 : 12

Write an equation that represents the line use exact numbers
Answer:
hello
f (2 ) = 6 et f ( 0 ) = 3
( 3 - 6 ) / ( 0 - 2 ) = - 3/- 2 = 3/2
ax = 3 x /2
f (0) = 3 ⇔ b = 3
f (x) = 3 x /2 + 3
also f ( 0) = 0 + 3 = 3
sorry
y = ax + b
b = 3
since the line cuts the y-axis in 3
then for a ? which is the slope..
we take 2 points on the line (0 ; 3) and (2 ; 6)
we move 2 units to the left to go up 3 units
so a = 3/2
=> y = 3/2x + 3
or
f(x) = 3/2x + 3

a=1/2(2x6)x4 i need helppp !!
Answer:
A=24
Step-by-step explanation:
First, we do the equations in the brackets(2x6) which is 12.
Before that, there is a 1/2 which means dividing whatever is inside the brackets by 2 which then becomes 6.
Then we x4 so the answer is 24.
a = 24
Step-by-step explanation:
[tex]\rm \: a = \frac{1}{2} (2 \times 6) \times 4 \\ \\ \rm a= \frac{1}{2} (12) \times 4 \\ \\ \rm a= \frac{12}{2} \times 4 \\ \\ \rm \: a = 6 \times 4 \\ \rm \: a = 24[/tex]
A football is punted from a height of 2.5 feet above the ground with an initial vertical velocity of 45 feet per second.
Write an equation to model the height h, in feet, of the ball t seconds after it has been punted.
The football is caught at 5.5 feet above the ground. How long was the football in the air?
Answer:
1.451 seconds. Hurry.
Step-by-step explanation:
The position(height, h) of the foot ball will be given by the equation:
h = -32.2t^2 + 45t + 2.5
The term -32.2t^2 consists of the acceleration caused by gravity at Earth's surface ( -32 ft/sec^2) and the term +45t accounts for the initial velocity. The + is assigned since the ball is moving vertically from ground. The negative sign in -32t^2 is due to the acceleration being towards ground. The term 2.5 accounts for the fact that the initial height of the ball is 2.5 feet above ground.
We can either calculate or graph with this function to find the time the ball spends in the air:
Calculate:
h = -32.2t^2 + 45t + 2.5
We need a value of t that would cause h to be 5.5 feet, the level it was caught:
5.5 = -32.2t^2 + 45t + 2.5
-32.2t^2 + 45t + 2.5 = 5.5
-32.2t^2 + 45t -3.0 = 0
Solve for t using the quadratic formula. I get a value of 1.33 seconds.
Graph:
See the attached graph. It confirms the 1.33 second value

(B)They all move 1 unit to the left.
(C)They all move 1 unit down.
(D)They all move 1 unit up.
Answer:
D
Step-by-step explanation:
They all move 1 unit up.
The mapping notation essentially tells you, what you do to each point to get the image point.
In this case (x,y)→(x,y+1) is telling you, for any given coordinate on the original, you add 1 to its y coordinate. Adding 1 to a y coordinate moves it up one unit.

Donetta is investing $6000 in a stock fund that is offering a constant annual interest of 5%.
The interest in investing $6000 in a stock fund that is offering a constant annual interest of 5% is $300
What is interest?
Interest is the amount of money made from investing a particular amount of money over a period of time. It is given by:
I = PRT
I is interest, P is principal, R is rate and T is period
Donetta is investing $6000 in a stock fund that is offering a constant annual interest of 5%. Hence in one year:
I = 6000 * 5% * 1 year = 6000 * 0.05 * 1 = $300
The interest in investing $6000 in a stock fund that is offering a constant annual interest of 5% is $300

Answer:

Angles on a straight line will always add up to 180°
The sum of interior angles in a triangle is 180°
Question 7
a + 134° = 180°
⇒ a = 180° - 134°
⇒ a = 46°
b + 119° = 180°
⇒ b = 180° - 119°
⇒ b = 61°
a + b + c = 180°
⇒ 46° + 61° + c = 180°
⇒ c = 180° - 46° - 61°
⇒ c = 73°
Question 8
r + 126° = 180°
⇒ r = 180° - 126°
⇒ r = 54°
s + 145° = 180°
⇒ s = 180° - 145°
⇒ s = 35°
r + s + t = 180°
⇒ 54° + 35° + t = 180°
⇒ t = 180° - 54° - 35°
⇒ t = 91°
