The ratio of Val's savings to Dan is 2:3 at first. After Dan spent P3000.00, Val's saving became 11/3 more of that Dan's remaining savings. What is the total amount of saving the two had at first
Answer:
P.7500.00
Step-by-step explanation:
We are told that:
The ratio of Val's savings to Dan is 2:3 at first.
Now, Dan spent P3000.00 and Val's saving became 1⅓ more of that Dan's remaining savings.
Let's say the total amount of savings they had at first was x.
Thus;
Val had: 2x/5
Dan had: 3x/5
Now, Dan spent P3000.00.
So amount Dan has left = (3x/5) - 3000
We are told Val's savings is now 1⅓ = 4/3 times that of Dan's remaining savings
Thus; 2x/5 = (4/3)((3x/5) - 3000)
2x/5 = 12x/15 - 4000
Multiply through by 15 to get;
6x = 12x - (3000 × 15)
6x = 12x - 45000
Rearranging, we have;
12x - 6x = 45000
6x = 45000
x = 45000/6
x = P.7500

Answer:
#7.
The domain is {-3,0,4}
the range is {-5,0,1,7}
not a function
#8
D={3,6,12,18}
R={5,7,9,10}
not a function
Step-by-step explanation:
First, 7.
the domain is the all of the x values, in numerical order, listed once, even if it repeats.
D={-3,0,4} (notice how -3 is listed twice; despite that, we only list it once)
the range is all of the y values, in numerical order, listed once, even if the numbers repeat
R={-5,0,1,7}
A function can have the range (y values) repeat, however, the domain (x values) cannot repeat.
Therefore, this is not a function, since -3 is listed twice.
For 8.
The domain, can be listed as
D={3,6,12,18}
And the range as
R={5,7,9,10}
Notice how it says that if 6 is the input (x), the output (y) can be 5 or 10. Since we said the domain CANNOT repeat, this isn't a function.
Hope this helps!

Answer:
32
Step-by-step explanation:
You use angle chasing. Since a triangle's angle has to add up to 180, the other angle is 180-79-69. This gives 32. So angle E is 32 degrees. Since they are parallel, that means that E equals to D. That means that D is 32, so 32 is now the answer.

Compute the coefficient of determination. Round your answer to four decimal places. A regression equation is obtained for a set of data points. It is found that the total sum of square is 103.5, the regression sum of squares is 89.8, and the error sum of squares is 13.7.
a. 0.1324
b. 0.1526
c. 0.8676
d. 1.1526
Answer:
0.8676
Step-by-step explanation:
Given that :
Total Sum of Square (SST) = 103.5
Regression Sum of Square (SSR) = 89.8
Erroe Sum of Square (SSE) = 13.7
The Coefficient of determination (R²) :
R² = SSR / SST
R² = 89.8 / 103.5
R² = 0.8676328
R² = 0.8676

In an interval whose length is z seconds, a body moves (32z + 2z^ 2 ) ft. What is the average speed v of the body in this interval?
This question is incomplete, the complete question is;
In an interval whose length is z seconds, a body moves (32z + 2z²) ft.
What is the average speed v of the body in this interval?
Answer: the average speed v of the body in this interval is 32 + 2z ft/s
Step-by-step explanation:
Given that;
Length of travel = z seconds
also the body moves (32z + 2z²) ft
i.e
distance travelled = (32z + 2z²) ft
average speed v of the body in this interval = ?
Now to get the Average Speed
we simply say;
Average Speed V = (32z + 2z²) / z
Average Speed V = 32 + 2z ft/s
Therefore the average speed v of the body in this interval is 32 + 2z ft/s

What is 2 1/2 - 3/8 as a fraction
Answer:
[tex]\frac{17}{8}[/tex] or [tex]2\frac{1}{8}[/tex]
Step-by-step explanation:
First we will convert the first term into an improper fraction. We multiply the whole number into the denominator and add the product to the numerator.
[tex]2\frac{1}{2}[/tex][tex]-\frac{3}{8}[/tex]
[tex]\frac{5}{2}[/tex][tex]-\frac{3}{8}[/tex]
Then we will multiply the first term by 4/4 to match the denominator of the second term..
[tex]\frac{5}{2}[/tex] * [tex]\frac{4}{4}[/tex] = [tex]\frac{20}{8}[/tex]
Finally we subtract.
[tex]\frac{20}{8}[/tex][tex]-\frac{3}{8}[/tex] = [tex]\frac{17}{8}[/tex]
The solution of the given fractional expression is 17/8.
What is a fraction?A fraction is a numerical quantity that represents a part of a whole or a quotient of two quantities. It consists of a numerator (the top number) and a denominator (the bottom number), separated by a horizontal line.
The numerator represents the number of equal parts being considered, while the denominator represents the total number of parts that make up the whole.
First convert the mixed fraction into the whole fraction and solve further to get the final solution.
The given fractional expression will be solved as,
[tex]E = 2\dfrac{1}{2}-\dfrac{3}{8}\\\\E = \dfrac{5}{2}-\dfrac{3}{8}\\\\E = \dfrac{20-3}{8}\\\\E = \dfrac{17}{8}[/tex]
Hence, the solution will be 17/8.

The distance a spring will stretch varies directly how much weight is attached to the spring if a spring stretches 6 inches with 80 pounds attached how far will it stretch with 55 pounds attached? Round to the nearest 10th of an inch
Answer:
The spring will stretch 4.1 inches
Step-by-step explanation:
Direct Proportions
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y = kx
Where k is the constant of proportionality.
Let's call:
y = distance a spring stretches
x = weight attached to the spring
We know when x=80 pounds, y=6 inches, thus:
6 = 80k
Solve for k:
[tex]k=\frac{6}{80}=\frac{3}{40}[/tex]
The equation is now:
[tex]\displaystyle y = \frac{3}{40}x[/tex]
When x=55 pounds are attached:
[tex]\displaystyle y = \frac{3}{40}\cdot 55[/tex]
Calculating:
y = 4.1 inches
The spring will stretch 4.1 inches

Given a Segment AB find the distance; B = 30 and A = 10
Answer:
use formula of distance ;
Step-by-step explanation:
d = distance
(x_1, y_1) = coordinates of the first point
(x_2, y_2) = coordinates of the second point
so d is √((x_2-x_1)²+(y_2-y_1)²)
to find the distance between any two points.
taking A as x coordinate and B as y coordinate ie
A= [10,0]; B= [0,30]
[10 is x1 ,0 is y1 ]; [0is x2 and 30 is y2]
putting values in distance formula
√(0-10)²+(30-0)²
= √( -10 )²+(30)²
=[tex]\sqrt[/tex] 100+900
=√1000
= 31.622
the distance between ab is 31.62 or√1000

Answer:
APtₙ = (n-2)k² + (2n - 3)k + nStep-by-step explanation:
Given sequence:
-k² - k + 1, k + 2, k² + 3k + 3, 2k² + 5k + 4, ...We can see apart from the second term all terms are 2nd degree trinomial so it is not a GP.
Let's find the difference: to determine if it is a AP:
k + 2 - (-k² - k + 1) = k + 2 + k² + k -1 = k² + 2k + 1k² + 3k + 3 - (k + 2) = k² + 3k + 3 - k - 2 = k² + 2k + 12k² + 5k + 4 - (k² + 3k + 3) = 2k² + 5k + 4 - k² - 3k - 3 = k² + 2k + 1As we see the difference is common and it confirms the sequence is AP.
First term is
a₁= -k² - k + 1Common difference is
d = k² + 2k + 1nth term is:
tₙ = a₁ + (n-1)dtₙ = -k² - k + 1 + (n-1)(k² + 2k + 1) =-k² - k + 1 + (n-1)k² + (n-1)*2k + n-1 =(n-2)k² + (2n - 3)k + nSelect the expressions that are equivalent to 8(6m).
