At what interest rate will P20,000 accumulate to P26,080 in 8 years time?
Answer:
Rate of interest = 3.8%
Step-by-step explanation:
Given:
Initial amount p = 20,000
Final amount p + I = 26,080
Number of year t = 8 year
Find:
Rate of interest
Computation:
I = 26,080 - 20,000
I = 6,080
I = PRT
6,080 = (20,0000)(r)(8)
Rate of interest = 3.8%
Zoe and Maria plan to hike at a rate of 3 miles per hour and canoe at a rate of 6 miles per hour. They want to travel no more than 8 hours and cover at least 40 miles in one day. Which system of inequalities models the situation?
Answer:
h + c ≤ 8
3h + 6c ≥ 40
where h is the number of hiking hours
c is the number of canoeing hours
Step-by-step explanation:
Here, we want to write a system of inequalities;
Let number of hiking hours be h and the number of canoeing hours be c
h + c ≤ 8
Covering at least 40 miles;
Recall;
distance = speed * time
for 3 miles, h hours, we have 3h miles
for 6 miles , c hours , we have 6c
At least 40 miles, inequality will be ;
3h + 6c ≥ 40

5(2t - 3) – 7.5t = 0.5(12 – t)
PLEASEEEE HELP ME
Answer:
t = 7
Step-by-step explanation:
5(2t - 3) – 7.5t = 0.5(12 – t)
5*2t - 3*5 - 7.5t = 12*0.5 - t *0.5
10t - 15 - 7.5t = 6 - 0.5t {Now, combine like terms}
10t - 7.5t - 15 = 6 - 0.5t
2.5t -15 = 6 - 0.5t {Add 15 to both sides}
2.5t = 6 - 0.5t + 15
2.5t = 21 - 0.5t { Add 0.5t to both sides}
2.5t + 0.5t = 21
3t = 21 {Divide both sides by 3}
t = 21/3
t = 7

B. Encuentre su tasa unitaria en millas por minuto. (Redondea a la décima de milla más cercana)
PLZZZ HELPPPP PLZZZ......
Answer:
45 units squared
Step-by-step explanation:
Basically you know that two parts of the square is equal to a whole, as 50 plus 50 is 100.
So on the left diagonal, it is equal to 3 units squared, since there are 6 parts and each unit diagonal is equal to 1/2 of a square.
On the right side, there are also 3 units squared, since there are 6 parts and blah blah blah.
Even if it looks different, two partial squares will still add up to one whole square. So the diagonals are equal to 6 units.
Then you can add up your full squares that you already know of so there are 9 units on the bottom row and another 9 on top.
Then you add 7 for the third layer and 6 more on the next.
There are 4 on the next layer and 3 and another square.
So 9 + 9 + 7 + 6 + 4+ 3 + 1.
That is 39.
But you may say: BUT WAIT SCOTTY THERE IS ANOTHER 6
me: oh yah i frgot bro thanks m8
So since there is another 6 more units, it is 45 since 39 + 6 is 45.
Hope this helps boi
Frank bought 4.3×10^4 yards of carpet to install in the new house. His wife said "We needed 5,000 yards! You didn't buy enough!"
Who is correct, Frank or his wife? Demonstrate with math to show your answer.
Answer:
Frank is correct.
Step-by-step explanation:
To convert 4.3 x [tex]10^{4}[/tex] into regular notation I move the decimal 4 places to the right and get 43,000. This is way more than enough for the 5,000 yards needed for the carpet. So, Frank's wife is wrong about it not being enough.
Answer:
The husband is correct. They needed 5,000, and he brought 43000.
Step-by-step explanation:
4.3*(10^4)=43000

to solve for the sine you have to look at the hypotenuse aka the opposite side.
Sorry I cannot solve for the Sin, I am a child of God, a brother to Jesus. I do not believe in sins, since I have never sinned in my life. I have been enlightened from the gods themselves. They taught me right from wrong and wrong from right. Anybody can be forgiven for their sins, such as now. Your sins are now forgiven by a higher being.

Part C
What does the point (1, 0.75) represent in this situation? What does the point (0, 0) represent?
1 cookie costs $0.75; no cookies cost $0
1 cookie costs $7.50; no cookies cost $0
0.75 dozen cookies cost $1; 0 dozen cookies cost $0
1 dozen cookies cost $0.75; 0 dozen cookies cost $0
Answer:
A=3rd one
B=Yes, Its a straight line through the origin
C=1 cookie costs $0.75
Step-by-step explanation:
The reason why C is $0.75 is because of ratios.
2:$1.5
2 divided by 2=1
2 divided by $1.50=$0.75
$0.75 per cookie

What is the scale factor of ABC to DEF?
Answer:
The answer is 8.
Step-by-step explanation:
Since you are looking for the scale factor of ABC to DEF the answer is 8 because DEF is 8 times larger than ABC.
The scale factor of ABC to DEF would be 1/3 Thus, the correct option is B.
What is the scale factor?The scale factor states the scale or measurement by which a figure is bigger or smaller than the other figure. The size by which the figure would be reduced or enlarged is called its scale factor.
In a triangle ABC and DEF
The sides are as follows 5 to 15 which is thrice the length of the side in ABC.
4 to 12 which is 3 times the length of the side in ABC.
3 to 9 which is 3 times the length of the side in ABC.
Thus, the scale factor would be 1/3.

solve for x and y graphically, 2y= 3x+1 and y=2x+3
Answer:
[tex](-\frac{1}{3},\frac{1}{2} )[/tex] , [tex](-\frac{3}{2} ,3)[/tex]
Step-by-step explanation:
2y = 3x + 1
y = 2x + 3
Graph 2y = 3x + 1.
Divide each term by 2 and simplify.
[tex]y=\frac{3x}{2}+\frac{1}{2}[/tex]
Rewrite in slope-intercept form.
[tex]y=\frac{3}{2}x+\frac{1}{2}[/tex]
Use the slope-intercept form to find the slope and y-intercept.
Find the values of m and b using the form y = mx + b.
[tex]m=\frac{3}{2}[/tex]
[tex]b=\frac{1}{2}[/tex]
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: [tex]\frac{3}{2}[/tex]
y-intercept: [tex](0,\frac{1}{2} )[/tex]
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.
Find the x-intercept.
x-intercept(s): [tex](-\frac{3}{2},0 )[/tex]
y-intercept(s): (0, 3)
Create a table of the x and y values.
_x_|_y_
[tex]-\frac{3}{2}[/tex] | [tex]0[/tex]
[tex]0[/tex] | [tex]3[/tex]
Graph the line using the slope and the y-intercept, or the points.
Slope: 2
intercept: (0, 3)
_x_|_y_
[tex]-\frac{3}{2}[/tex] | [tex]0[/tex]
[tex]0[/tex] | [tex]3[/tex]
Graph y = 2x + 3
Use the slope-intercept form to find the slope and y-intercept.
Slope: 2
intercept: (0, 3)
x-intercept(s): [tex](-\frac{3}{2},0)[/tex]
y-intercept(s): (0, 3)
