Answer:
The angles are supplementary.
Step-by-step explanation:
Both angles lie on a straight line. When two angles are right next to each other on a straight line, then they add up to 180...therefore they are supplementary.

i need help solving this question
Answer:
4 1/6
Step-by-step explanation:
First, you have to convert any mixed numbers to fractions.
Then your initial equation becomes:
25/8÷3/4
Second, you have to apply the fractions formula for division.
= 25 x 4
------------- (You will be dividing.)
8 x 3
=100/24
And if you simplify 100/24, the answer will become:
4 1/6
I hope this helps. :)

How is the graph of y = - 4x2 – 5 different from the graph of y = -4x2?
A. It is shifted 5 unit(s) down.
C. It is shifted 5 unit(s) up.
B. It is shifted 5 unit(s) left.
D. It is shifted 5 unit(s) right.
Answer:
C. It is shifted 5 unit(s) up.
Step-by-step explanation:
The y-intercept of the first equation is –5. The y-intercept of the second equation is 0. This means that it moves up by 5 units.

During a high school baseball tournament, Lexile hits a pitch and the baseball stays in the air for 4.42 seconds. The function describes the height over time, where h is its height, in yards, and t is the time, in seconds, from the instant the ball is hit: h(t) = - 5t ^ 2 + 22t + .5
Answer:
a) The maximum height that the ball reaches is 73.1 meter
b ) The time elapsed when the ball reaches its maximum height of flight = 2.2 seconds
Step-by-step explanation:
The complete question is
During a high school baseball tournament, Lando hits a pitch and the baseball stays in the air for 4.42 seconds. The function h(t) = -5t2 + 22t + 0.5 describes the height over time, where h is its height, in meters, and t is the time, in seconds, from the instant the ball is hit. a. What is the maximum height the ball reaches? b. What will be the time elapsed when the ball reaches its maximum height of flight?
Solution:
For maximum height
[tex]\frac{dh}{dt} =0[/tex]
[tex]\frac{d(5t^2 + 22t + 0.5)}{dt}\\ 10t + 22 = 0\\t = 2.2[/tex]seconds
a) Maximum height
[tex]5 * t^2 + 22t + 0.5[/tex]
[tex]= 5 * 2.2 *2.2 + 22 * 2.2 + 0.5 \\= 73.1[/tex]
b) Time elapsed when the ball reaches maximum height is 2.2 seconds
25 points. Which problem will graph as shown?
A) 3x - 5 ≥ -14
B) 3x - 5 ≤ -14
C) 3x - 5 > -14
D) 3x - 5 < -14
Answer:
D
Step-by-step explanation:
We can work backwards.
First, notice that we have an open circle. So, we do not have "or equal to." So, we can ignore A and B.
Our final answer is all values less than -3. So:
[tex]x<-3[/tex]
We can multiply both sides by 3:
[tex]3x<-9[/tex]
And then subtract 5 from both sides:
[tex]3x-5<-14[/tex]
So, the answer that matches this will be D.
Instead of working backwards, you can also just solve each inequality. Since we have an open circle, we only need to solve C and D. If we solve C, we get x > -3, and if we solve D, we get x < -3 (as desired). So, D matches the graph shown.

Karen recorded the numbers of people getting off her tram. The mean number for 10 stops is 6.3. After the tram stops at the 11th stop, the mean is 8. How many people got off the tram at the 11th stop?
Answer:
32 people got off
Step-by-step explanation:For the 10th stop, we can get the total number of people that have gotten off
Mathematically, this is the product of the mean and the number of stops
= 10 * 6.3 = 63 people
Now, for the 11th stop, the total becomes
11 * 8.6 = 94.6
If x = 8, what is the value of 4x + 6?
I NEED HELP! I’m on a test!!
Answer:
=38
Step-by-step explanation:
Use substitution :3
4(8)+6=38
substitute x to 8 then calculate!
There you'll get your answer.
the required value of expression 4x + 6 is 38 when x = 8.
If x = 8, what is the value of 4x + 6 to be determine.
In mathematics, it deals with numbers of operations according to the statements.
The equation is the relationship between variables and is represented as y = 4x +8 is an example of a polynomial equation.
Here, the expression is given as,
y = 4x + 8
now we have x = 8, put this x in y
y = 4(8) + 6
Solving the equation using the PEMDAS rule of mathematics
1St open the parenthesis of 8 then multiply this 8 by 4.
y = 4*8 +6
y = 32 + 6
Now adding 32 and 6 will give 38
y = 38
Thus, the required value of expression 4x + 6 is 38 when x = 8.

Question 1
Find the measure of each angle indicated.
Answer:
90
Step-by-step explanation:
Answer:
90
Step-by-step explanation:
x + 70 =120 {Exterior angle theorem}
x = 120 - 70
x = 50
y = x {Vertically opposite angles}
y = 50
z + 50 + 40 = 180 {Angle sum property}
z + 90 = 180
z = 180 - 90
z = 90

find the simple interest on each amount 1500 at 11% for two years
Answer:
330.00
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 11%/100 = 0.11 per year,
then, solving our equation
I = 1500 × 0.11 × 2 = 330
I = $ 330.00
The simple interest accumulated
on a principal of $ 1,500.00
at a rate of 11% per year
for 2 years is $ 330.00.
If a company employed 50 people in 1995, and tripled their employment by 2005, how many total people would be employed if there are 40% more employees than in 2005 by 2015?
Answer:
210 people
Step-by-step explanation:
so we know that the number of employees in 2005 is (50)3= 150
so taking 14/10* 150= we get 14*15= 210 people
