Answer:
241.20 dollars
Step-by-step explanation:
Use the equation I=prt, where I is the interest and p is the percentage of simple interest, which is 6% or 0.06. T is the rate of time in years. R is the amount Felix deposited. Our equation would be:
I=(0.06)(1340)(3)
I=(0.18)(1340)
I=$241.20

Answer:
The answer is x = 3
Step-by-step explanation:
5x + 9 = 24
5x +9 -9 = 24 - 9
5x = 15
x = 15/5 = 3
Therefore, x = 3
Kelly multiplied 5 to each side when she solved for x, which is incorrect.
Answer:
Kelly had incorrectly solved for [tex]x[/tex] where she had multiplied by [tex]5[/tex] instead of dividing by [tex]5[/tex] to find for [tex]x[/tex].
Step-by-step explanation:
How Kelly should have solved it:
[tex]5x+9 = 24[/tex]
[tex]5x + 9-9= 24-9[/tex]
[tex]5x=15[/tex]
[tex]5x\div 5=15\div 5[/tex] (mistake occurred during this step in Kelly's work where she had multiplied by [tex]5[/tex])
[tex]x=3[/tex]
Checking:
To check if [tex]x=3[/tex], we can use substitution:
[tex]5x+9 = 5(3)+9[/tex]
[tex]=15+9[/tex]
[tex]=24[/tex]
∴ The solution for [tex]x[/tex] is correct.

-Ꮾb > 42 or Ꮞb + Ꮾ > 2
Answer:
b<-7 or b>-1
Step-by-step explanation:
explanation: -6b>42 turns into -42>6b then divide by 6 on both sides and you get -7>b
for the other inequality, you take 4b+6>2 and then subtract6 from both sides, from there you will get 4b>-4 and that will be b>-1

Explain how to change a negative exponent to a positive one
Answer:
Flip the fraction that you are applying the exponent to, if it's a whole number, just imagine it's over one and flip it that way.
Explanation:
If you have 3/5 ^-3
You would flip the fraction to 5/3, then the exponent turns to positive 3
So 5/3 ^3
For a whole number, for example, 6, ^-2
In other words, it's 6/1 ^2, so you would make it 1/6, then the exponent turns positive.
So 1/6 ^2
Hope this helped :)
To change a negative exponent to a positive one, a flip it into a reciprocal.
Here,
We have to explain, change a negative exponent to a positive one.
What is Reciprocal?
The inverse of a number is called Reciprocal.
Now,
Let a number is, [tex]5^{-2}[/tex]
Then change it into positive exponent as;
Take reciprocal of [tex]5^{-2}[/tex], we get;
⇒ [tex](\frac{1}{5} )^2[/tex]
Hence, reciprocal of [tex]5^{-2}[/tex] = [tex](\frac{1}{5} )^2[/tex]
So, To change a negative exponent to a positive one, a flip it into a reciprocal.

The 24 girls in 20 boys to school gym clothes have to be split into groups for a team building activity. If each group must be identical, what is the maximum number of groups that can be made?
Answer: 4
Step-by-step explanation:
Given: Total girls = 24
Total boys = 20
If each group must be identical, then the maximum number of groups that can be made = GCD(24,20) [GCD= Greatest common divisor]
Since 24 = 2 x 2 x 2 x 3
20 = 2 x 2 x 5
GCD(24,20)= 2 x 2 = 4
Hence, the maximum number of groups that can be made = 4

The rate of change for the given data is -3. Therefore, option A is the correct answer.
The coordinates from the given data are (-1, 5) and (2, -4).
What is rate of change and initial value of a function?The rate of change, or the slope, is calculated as Δy/Δx , or (y2−y1)/(x2−x1). The slope-intercept equation of a line is y=mx+b , where m is the slope and b is the initial value.
Here, (x1, y1)=(-1, 5) and (x2, y2)=(2,-4)
Rate of change = (-4-5)/(2+1)
= -9/3
= -3
The rate of change for the given data is -3. Therefore, option A is the correct answer.

The value of a baseball player's rookie card began to increase once the player retired. When he retired in 1996 his card was worth $5.71 The value has increased by $1.98 each year since then. Express the relationship relating the value of the card y in dollars and the number of years x the player has been in retirement with an equation. Is the relationship between x and y proportional? What was the value of the card in 2002 ?
Answer:
Step-by-step explanation:
The number of years between 1996 to 2002 will be:
= 2002 - 1996
= 6 years
The relationship relating the value of the card y in dollars and the number of years x the player has been in retirement can be expressed as an equation in the form of:
y = 5.71 + 1.98x
where x = 6 years
y = 5.71 + 1.98(6)
y = 5.71 + 11.88
y = $17.59
The value of the card in 2002 is $17.59.
The relationship between x and y isn't proportional in this case.
An object is thrown into the air. The equation for the object's heights at
time t seconds after launch is H(t) = -4.9t2 + 13.4t + 24.9, where H is in
meters.
Missing Part of the Question:
- The time required for the rocket to reach its maximum height
- The maximum height of the rocket
Answer:
a. Time to reach maximum height is 1.37 seconds
b. Maximum Height = 34.1 metres
Step-by-step explanation:
Given.
H(t) = -4.9t² + 13.4t + 24.9
Solving (a): Time taken to reach maximum height.
A quadratic equation is:
f(x) = ax² + bx + c
Where
a = -4.9
b = 13.4
c = 24.9
This required time is represented by the vertex and is calculated as thus:
t = -b/2a
Substitute values for b and a
t = (-13.4)/(2 * -4.9)
t = -13.4/(-9.8)
t = 13.4/9.8
t = 1.37 (approximated)
Hence the time to reach maximum height is 1.37 seconds
b. Maximum height
Here, we simply substitute 1.37 for t in
H(t) = -4.9t²+ 13.4t + 24.9
Maximum Height = -4.9 * 1.37² + 13.4 * 1.37 + 24.9
Maximum Height = -4.9 * 1.8769 + 13.4 * 1.37 + 24.9
Maximum Height = -9.19681 + 18.358 + 24.9
Maximum Height = 34.06119
Maximum Height = 34.1 metres (approximated)
When x = 2,what is the value of y for the equation – 3x + 2y = 10?
Answer:
y=x+5
Step-by-step explanation:
Answer:
[tex] \huge{ \boxed{ \bold{ \tt{y = 8}}}}[/tex]
☪ What is the value of y for the equation given below when x = 2 ?
-3x + 2y = 10☪ Step - by - step explanation :
[tex] \sf{ - 3x + 2y = 10}[/tex]plug the value of x ( i.e 2 )
➳ [tex] \sf{ - 3 \times 2 + 2y = 10}[/tex]
Remember : Multiplying or dividing a negative integer by a positive integer gives a negative integer.
➳ [tex] \sf{ - 6 + 2y = 10}[/tex]
Move 6 to right hand side and change it's sign
➳ [tex] \sf{2y = 10 + 6}[/tex]
Add the numbers : 10 and 6
➳ [tex] \sf{2y = 16}[/tex]
Divide both sides by 2
➳ [tex] \sf{ \frac{2y}{2} = \frac{16}{2}} [/tex]
➳ [tex] \boxed{ \sf{y = 8}}[/tex]
——————————————————
✏ Now, let's check whether the value of y is 8 or not !
✑ Verification :
[tex] \sf{ - 3x + 2y = 10}[/tex]
→ [tex] \sf{ - 3 \times 2 + 2 \times 8 = 10}[/tex]
→ [tex] \sf{ - 6 + 16 = 10}[/tex]
→ [tex] \sf{10 = 10}[/tex]

Can someone help me with my algebra?
Answer:
C. -3
Step-by-step explanation:
You can do this using two different methods.
First, slope is written rise over run, or y over x. We can find two points and count how much we need to rise and run. The graph already includes the points (2,-3) and (-1, 6), which we will use. If you carefully look at the graph, you can see that if you start from the point (2,-3), you can rise 9 and run -3 to get to the point (-1, 6), which brings me to the next step. As I stated in the beginning, slope is written rise over run. Therefore, the slope is 9/-3, which simplifies to -3, answer choice C.
Another way you can do this is subtracting the y's and subtracting the x's in the same order. The y's go over the x's, and is basically written as a fraction. For this method, we still need two points. We will use the same points as above and listed on the graph, points (2,-3) and (-1, 6). The y's are -3 and 6, and the x's are 2 and -1. Now, subtract.
-3-6 =-9=-3
2-(-1)= 3
As you can tell, both methods of solving for slope worked, and the answer is choice C.
I hope this helps you!! Have a great day ^^

(c) Given that the body decelerate at 1.25 m/s[tex]^{2}[/tex]
Answer:
Below.
Step-by-step explanation:
(a)
The acceleration = the slope of the graph (change of velocity / time)
= 25/15
= 1.67 m/s/s.
(b)
The distance moved = the area under the graph for the first 0 seconds,
= area of the first triangle + area of the rectangle with height 25 and length (40 - 15)
= 1/2 * 15 * 25 + (40-15) * 25
= 187.5 + 625
