Answer:
35 would be your answer
Step-by-step explanation:
3x-24=81
So first off, add 24 to 24 and 81
You would get 3=105
Now divide 3/3 and 105/3 which will get you 35!
Hopefully this helps!
Answer: 35
Step-by-step explanation:
you add 24 to the other side of the equal sign and you get 105. then you’re left with 3x=105 and you divide 105 by 3 and get 35=x

Two angles are complementary. The measure of one angle is 15 ° more than twice the other. What is the measure of the smaller angle? 1) 25 ° 2) 35 ° 3) 55 ° 4) 65 °
Answer:
1) 25 °
Step-by-step explanation:
Two angles are complementary when the measure of the angles between sum up to 90°;
Given;
Angle 1 = a
Angle 2 = b
a = 15 + 2b
Angle a + Angle b = 90°
15 + 2b + b = 90
15 + 3b = 90
3b = 90 - 15
3b = 75
b = 25°

Answer:
The point in the middle at (0,0) is the origin. The line that goes up and down is the y-axis. The lign that goes left to right is the x axis. The y intercept is at (0,-5). The x intercept is at (6,0).
Step-by-step explanation:
The answer is attached.
What are intercepts?The point where the line or curve crosses the axis of the graph is called intercept.
xy-axes:- The x and y-axis are two important lines of the coordinate plane. The x-axis is a horizontal number line and the y-axis is a vertical number line.
xy-intercepts:-
If a point crosses the x-axis, then it is called the x-intercept. If a point crosses the y-axis, then it is called the y-intercept.

write the slope intercept form of the equation of the line that goes through the point (5,-6) and has a slope of 2
Answer:
y = 2x - 16
Step-by-step explanation:
Slope-intercept form: y = mx + b
Given:
Slope(m): 2
Point: (5, -6)
To write the equation in slope-intercept form we need to find the slope(m) and the y-intercept(b).
Since we were given the value of the slope, the only thing we have to do is find the y-intercept. To do this, input the values of the slope and the given point into the equation and solve for b:
y = mx + b
-6 = 2(5) + b
-6 = 10 + b
-16 = b
The y-intercept is -16.
Now that we know the slope and the y-intercept, we can write the equation:
y = 2x - 16
The function h(0) = -16t2 + vt + 10 gives the height of a platform diver above the water, in feet, t seconds after
Complete Question:
The height of a diver jumping from a diving platform is about [tex]h(t)= 16t^2 +11t+10[/tex], where h is the height of the diver in feet above the water and t is the time measured in seconds, when diving from a platform about 34.3 feet above the water with an upward initial velocity of 11 ft/sec.. After how many seconds is the diver's height above the water 15 feet?
Answer:
0.3125 seconds
Step-by-step explanation:
Given
[tex]h(t)= 16t^2 +11t+10[/tex]
Required
Time when the diver is above 15ft
This implies that h(t) = 15
So, we have:
[tex]15= 16t^2 +11t+10[/tex]
Collect Like Terms
[tex]0= 16t^2 +11t+10 - 15[/tex]
[tex]0= 16t^2 +11t-5[/tex]
[tex]16t^2 +11t-5=0[/tex]
Expand:
[tex]16t^2 + 16t - 5t - 5 = 0[/tex]
Factorize:
[tex]16t(t + 1) - 5(t + 1) = 0[/tex]
[tex](16t - 5)(t + 1)=0[/tex]
Split
[tex]16t - 5 = 0[/tex] or [tex]t + 1 = 0[/tex]
[tex]16t = 5[/tex] or [tex]t + 1 = 0[/tex]
Solve for t
[tex]t = 5/16[/tex] or [tex]t = -1[/tex]
[tex]t = 0.3125[/tex] or [tex]t = -1[/tex]
But time can't be negative. So:
[tex]t = 0.3125[/tex]
Hence, it will take the diver 0.3125 seconds to be at a height above 15 feet
It will take t = 0.3125 seconds is the diver's height above the water 15 feet.
Given ,
The height of a diver jumping from a diving platform is h
h(t) = [tex]-16t^{2} + vt + 10[/tex]
The diver's height above the water 15 feet
Velocity = v = 11 ft per second
We have to find, t seconds is the diver's height above the water 15 feet.
According to the question,
[tex]h(t) = -16t^{2} +vt+10[/tex]
Where v = 11, h(t) = 15
15 = -16[tex]t^{2}[/tex] + 11t + 10
15 - 10 = [tex]-16t^{2} + 11t[/tex]
5 = [tex]-16t^{2} +11t[/tex]
[tex]16t^{2} -11t +5= 0[/tex]
[tex]16t^{2} -16t - 5t + 5 = 0[/tex]
16t ( t - 1 ) - 5 ( t + 1 ) = 0
(16t - 5 ) ( t + 1 ) = 0
16t - 5 = 0
16t = 5
t = [tex]\frac{5}{16}[/tex]
t = 0.3125
And t + 1 = 0
t = -1
Time can not be negative so we can't take t = -1 .
So, The required value of time is t = 0.3125
Hence, it will take t= 0.3125 seconds is the diver's height above the water 15 feet.

Two groups of students order hamburgers and hot dogs at a local restaurant. The first group orders 3 hamburgers and 4 hot dogs for a total cost of $30.33. The second group orders 3 times as many hamburgers as the first group and 5 hot dogs. The second group’s total is $63.06. What is the cost of a hamburger at this restaurant?
Answer:
3.63666666667 or about $3.64
Step-by-step explanation:
63.06 - 30.33 = 32.73(this is the price for 9 hamburgers)
32.73/9 = 3.63666666667(The price for hamburgers.)
32. The length of a rectangle measures six more than the width. The perimeter of the rectangle is 38.
What are the dimensions of the rectangle?
Answer: 12.5
You start with the equations "2x +2y=38" and "6+x=y". By adding and subtracting in the second equation, you get "2x +2y=38" and "x-y=-6". When you multiply the second equation by 2, you get "2x-2y=-12."
subtracting the equations "2x +2y=38" and "2x-2y=-12" gets you to "4y=50", where you have to divide two sides by 4 and get "y=12.5"

Let a = 8i + 2j, b = –3i + j, and c = 2i – 5j, where i and j are unit vectors.
What is 4a + 2b – 9c in terms of i and j?
8i – 35j
8i – 2j
8i + 53j
8i + 55j
Answer:
D
Step-by-step explanation:
The value of the vector (4a + 2b – 9c) as per scaler multiplication of vector method is 8i + 55j.
What is vector?A vector is a physical quantity that has both magnitude and direction.
What is unit vector?A vector that has magnitude of 1 is called unit vector.
Given, a = 8i + 2j, b = –3i + j, and c = 2i – 5j.
In order to find the value of the vector (4a + 2b – 9c) in terms of i and j, we need to perform scaler multiplication of vector.
Here, i and j are unit vectors.
Therefore: (4a + 2b – 9c)
= 4(8i + 2j) + 2(–3i + j) - 9(2i – 5j)
= (32i + 8j - 6i + 2j - 18i + 45j)
= (8i + 55j)
Therefore, Option(D) is correct answer.

I think its the third because everyone added to the left is -2 from the right
Answer:
The answer is A becuase the initial value is what y is when x = 0 and if you see the pattern between 10 and 8 and also 8 and 6 you see the rate of change is -2. Just add 2 to y when x = 1 so 10 + 2 is 12 which gives the answer A.

the length of the floor is 32 m longed than it’s witdth and there is greater than 200 square meters. You will cover the floor completely with tiles. what will be the possible dimension of the floor?
with solution po sana ty pooooo
Answer:
Step-by-step explanation:
The area of the floor A = Length * Width
Given
A = 200 square meters
If the length of the floor is 32 m longed than it’s width then;
L = 32+W
A = LW
200 = (32+W)W
200 = 32W + W²
W²+32W-200 = 0
W = -32±√32²+800/2
W = -32±42.71/2
W = -32+42.71/2
W = 10.71/2
W = 5.35 m
L = 32+5.35
L = 37.35m
Hence the dimension is 5.35ft by 37.35m
