Three children each contributed toward a birthday present for their mother. The oldest contributed three times as much as the youngest, while the second oldest contributed 50 cents more than the youngest. If the present costs $10.50, how much did each contribute?
Answer:
Youngest child: $2
oldest child: $6
Second oldest: $2.50
Step-by-step explanation:
Youngest child= x
oldest child= 3x
Second oldest: .50+x
x+3x+.50+x=10.5
5x+.50=10.5
- .50= - .50
5x=10
divided both numbers by 5 and x is equal to 2. So, the youngest child is $2 and you add .50, which is $2.50, and thats for the second child. Last, you do 2 times 3 equals $6 which is the oldest child.
The youngest contributed $1.90, the oldest contributed $5.27, and the second oldest contributed $2.85.
Three children each contributing to their mother's birthday present. The eldest gave three times more than the youngest, while the second oldest contributed 50 cents more. If the gift costs $10.50 which is given in the question.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
Let the youngest sibling contribute the amount of x dollars
As per the given information,
3x + 0.50 x + x + x = 10.50
Apply the addition operation,
4.50x = 10.50
x = 10.50 / 6.50
Apply the division operation to get
x = 1.90
So the youngest sibling contributed = $1.90
The oldest contributed 1.90 × 3 = $5.27
And the second oldest contributed (1.50)1.90= $2.85
Therefore, the youngest contributed $1.90, the oldest contributed $5.27, and the second oldest contributed $2.85.

Verify the following identity:
[tex]\dfrac{1-\sin t}{\cos^2t}+\dfrac{1}{1-\sin t}=2\sec^2t[/tex]
We will simplify the left hand side of the equation to look like the right
[tex]\displaystyle \frac{1-sin(t)}{cos^{2}(t)} + \frac{1}{1 - sin(t)}[/tex]
taking the LCM
[tex]\displaystyle \frac{[1-sin(t)]^{2} + cos^{2}(t)}{[cos^{2}(t)][1 - sin(t)]}[/tex]
expanding the binomial in the numerator
[tex]\displaystyle \frac{[1 + sin^{2}(t) - 2sin(t) + cos^{2}(t)]}{[cos^{2}(t)][1 - sin(t)]}[/tex]
Since sin²x + cos²x = 1
[tex]\displaystyle \frac{[2 - 2sin(t)]}{[cos^{2}(t)][1 - sin(t)]}[/tex]
factoring out the 2 from the numerator
[tex]\displaystyle \frac{2[1 - sin(t)]}{[cos^{2}(t)][1 - sin(t)]}[/tex]
1-sin(t) will cancel out
[tex]\displaystyle \frac{2}{cos^{2}(t)}[/tex]
since cos²(t) = 1/(sec²(t))
[tex]2 sec^{2}(t)[/tex]
which is equal to the right hand side of our given equation.
So we verified the identity!

Graph x + 3y = 6.
please help
this is the photo of a answer
Answer:
see attached
Step-by-step explanation:
Both coefficients are divisors of the constant, so the intercepts are integer values. This makes it easy to graph the line using the x- and y-intercepts.
x-intercept
Set y=0 and you get ...
x = 6
y-intercept
Set x=0 and you have ...
3y = 6
y = 2 . . . . divide by 3
__
The intercepts (6, 0) and (0, 2) are points on the line. Plot these points and draw the line through them.
the function f(x)= (x-8) (x+2) (x+3) has which zeros
Answer:

x = 8
x + 2 = 0
x = -2
x + 3 = 0
x = -3
[tex](x-8)(x+2)(x+3) =0\\\\\implies x -8 =0~~~ \text{or}~~~x+2 =0 ~~~ \text{or}~~~x+3 = 0\\\\\implies x = 8 ~~~~~~~~ \text{or}~~~~~~x = -2 ~~~ \text{or}~~~ x = -3\\\\\\\text{Hence the roots are}~ 8, -2 ~\text{and} ~-3[/tex]

Answer: the answer is B which is x < -1
Step-by-step explanation: trust me bro and happy holidays :)
Answer:
[tex]\huge\boxed{B)\ x<-1}[/tex]
Step-by-step explanation:
Solve this inequality the same way you would solve an equation: by isolating x.
Simply subtract 6 from both sides to get -4x > 4. Then merely divide both sides by -4 to get x < -1. (Notice that when dividing by a negative number, you must flip the sign of the inequality.)

1. Which of the following is not an undefined term in
Euclidean geometry?
a. plane
b. point
c. bisector
d. line
Answer:
c. bisector
Explanation:
"There are, however, three words in geometry that are not formally defined. These words are point, line and plane, and are referred to as the 'three undefined terms of geometry'"
If point, line, and plane are all undefined terms in Euclidean geometry, then that only leaves one answer left, c. bisector.

Complete the sentences below based on the graph of the function.
Please help!
Answer:
20 km20 km/h5 km/hStep-by-step explanation:
We assume the graph is a plot of Sean's distance from home as he drives to work, works 8 hours, then drives home with a 2-hour stop along the way. It also appears that t is measured in hours after midnight.
The graph shows Sean's distance from home between 9 a.m. and 5 p.m. (t=17) is 20 km. Based on our assumptions, ...
Sean's workplace is located 20 km from his home.
__
Speed is the change in distance divided by the change in time. Between 8 a.m. and 9 a.m. Sean's position changes by 20 km. His speed is then ...
(20 km)/(1 h) = 20 km/h
Sean's speed driving to work was 20 km/h.
__
Between 5 p.m. (t=17) and 7 p.m. (t=19), Sean's position changes from 20 km to 10 km from home. That change took 2 hours, so his speed was ...
(10 km)/(2 h) = 5 km/h
Sean's speed between 5 p.m. and 7 p.m. was 5 km/h.
_____
Additional comment
The units of speed (kilometers per hour) tell you it is computed by dividing kilometers by hours. ("Per" in this context means "divided by".)
While the slope of the line on the graph between 5 p.m. and 7 p.m. is negative, the speed is positive. The negative sign means Sean's speed is not away from home, but is toward home. When the direction (toward, away) is included, the result is a vector called "velocity." Speed is just the magnitude of the velocity vector. It ignores direction.

V=AQT for A
Answer:
[tex]A = \frac{V}{QT}[/tex]
Step-by-step explanation:
To solve the problem you want to have A on one side, everything else on the other side. You can move over the variables by divind them from each side as shown:
[tex]AQT = V[/tex]
[tex]AQT = \frac{V}{1}[/tex]
[tex]AQ = \frac{V}{T}[/tex]

Answer:
Original Price = $23
Step-by-step explanation:
$5.75 is the price after a discount of 75%
Let the original price be x and x is 100% of the price
5.75 = 100%x - 75%x
5.75 = 25%x
The new price is 25% of the original because you are subtracting 75%
25% is also written as 0.25
5.75 = 0.25x
x = 5.75/0.25
x = 23
The original price is 23

Step-by-step explanation:
Each domain, or x value, can only be matched with one y value, so given this, the third one is the answer since every domain is only matched with one range, or in other words, there are no repeating domains in on the x row of the table.
The table that represents a function is
x 2 -2 4 -4
y 8 8 12 12
Option D is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
A function can have many to one but a function can not have one to many.
So,
From the table,
x 2 -2 4 -4
y 8 8 12 12
This is a many-to-one function.
All the other tables are one-to-many functions.
Thus,
The table that represents a function is
x 2 -2 4 -4
y 8 8 12 12

Answer:

Step-by-step explanation:
We just have to multiply the lenghts, but careful: the height is in cm. 100 cm = 1 m. Therefore 150cm = 1,5m.
V = 1.2 m * 1m * 1.5m = 1.8 m^3
