Answer:
Step-by-step explanation:
Given the following data;
Principal = $7,000
Interest = 3.5% = 3.5/100 = 0.035
To find the future value, we would use the compound interest formula;
[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
n is the number of times the interest is compounded in a year.
t is the number of years for the compound interest.
Substituting into the equation, we have;
[tex] A = 7000(1 + \frac{0.035}{n})^{nt}[/tex]

Answer:
There are 585 adults and children
Step-by-step explanation:
Let the number of adults be a, number of children be c and the number of seniors be a
Amount made per group;
adults; 52 * a = 52a
Children : 26 * c = 26c
Seniors = 20 * s = 20s
Adding all will give 20,490
52a + 20s + 26c = 20 490 ••••(i)
Now let us work with the ratios;
a : s = 6 : 1
a/s = 6/1
a = 6s •••••(ii)
Lastly;
a/c = 4/9
4c = 9a ••••(ii)
We want to get a + c
From the first equation , let’s substitute
52(6s) + 20s + 26c = 20,490
26c = 6.5 (4c)
but 4c = 9a; 6.5(9a)
But a = 6s
So we have; 6.5(9)(6s) = 351s
so we have;
312s + 351s + 20s = 20,490
683s = 20,490
s = 20490/683
s = 30
Recall;
a = 6s = 6 * 30 = 180
4c = 9a
4c = 9 * 180
c = (9 * 180)/4 = 405
So the total number of children and adult is a + c
405 + 180 = 585

which theorem is correct
Answer:
The SSS theorem
Step-by-step explanation:
Answer:
SAS Theorem
Step-by-step explanation:
You can tell that the triangles are similar because of the SAS (side-angle-side) theorem.
This is because you already know that two of the sides are congruent since AB and CD were shown to be congruent in the image, and AC and CA are congruent because they're shared. You know that there are similar angles because of the Alternate Interior Angles Theorem*: because of it, you know ∠ACD and ∠CAB are similar because the lines that their transversal intersects are parallel.
*The Alternate Interior Angles Theorem states that if two lines are parallel, the alternate interior angles formed by a transversal are congruent.

Travis, Jessica, and Robin are collecting donations for the school band. Travis wants
to collect 20% more than Jessica, and Robin wants to collect 35% more than Travis.
If the students meet their goals and Travis collects $43, how much money did they collect
in all?
Answer:
their total collected is $135.45
Step-by-step explanation:
travis collect 20% more than Jessica
if travis collect $43 then
20% of 43
43 × 20 ÷ 100 = $8.6
Jessica collected $8.6 less than travis
$43 - $8.6 = $34.4
and Robin collect 35% more than travis
35% of 43
43 × 35 ÷ 100 = $15.05
therefore Robin collect $15.05 more than travis
$43 + $15.05 = $58.05
their total collected
Jessica collected $34.4
robin collected $58.05
travis collected $43
total
$34.4 + $58.05 + $43 = $135.45
8. Identify the x and y intercept of the equation:
12x - 8y = 48
Answer:
X- intercept(S) : (4,0)
Y- Intercept(S) : (0, -6)
Step-by-step explanation:
To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for Y.
Hopes this helps!
The x- intercept (4, 0) and y intercept ( 0, -6).
What is Intercept?The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.
when the independent variable is 0 and you want to know the value of the dependent variable (zero).
Given:
Equation: 12x - 8y = 48
Now, for x- intercept put y= 0
12x - 8(0)= 48
12x= 48
x= 4
and, for y- intercept put x= 0
12(0) - 8y= 48
-8y= 48
y= -6
Hence, the x- intercept (4, 0) and y intercept ( 0, -6).

Answer:
y-9=7(x+5)
Step-by-step explanation:
Point-Slope form is
[tex]y-y_{1} =m(x-x_{1} )[/tex]
where m equals the slope of the line and y1 and x1 represent the y and x coordinates of one of the points on that line.
First, let's find the slope (change in y divided by the change in x):
[tex]\frac{9-(-5)}{-5-(-7)} =\frac{14}{2} =7[/tex]
Now, let's choose any one of the two points, I'll pick (-5,9), but (-7, -5) also works.
Substitute in the y value (in this case 9) for y1 and substitute the x value (in this case -5) for x1
We can also substitute the slope, m which we know is 7.
y-9=7(x-(-5)
y-9=7(x+5)

What is trigonometric ratio?Trigonometric ratios are the ratios of the length of sides of a triangle. These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle.
The basic trigonometric ratios formulas are given below,
sin θ = Perpendicular/Hypotenuse
cos θ = Base/Hypotenuse
tan θ = Perpendicular/Base
sec θ = Hypotenuse/Base
cosec θ = Hypotenuse/Perpendicular
cot θ = Base/Perpendicular
According to the question
In right angle Δ
Hypotenuse = 28
Base for ∠45° = b
Perpendicular for ∠45° = a
now , Using trigonometric ratio
sin θ [tex]= \frac{Perpendicular}{Hypotenuse }[/tex]
sin 45° = [tex]= \frac{a}{28}[/tex]
[tex]\frac{1}{\sqrt{2} } = \frac{a}{28}[/tex]
a = [tex]\frac{28}{\sqrt{2} }[/tex]
Hence, side of "a" of right angled triangle is [tex]\frac{28}{\sqrt{2} }[/tex] .

Step-by-step explanation:
What are the slope and the y-intercept of the linear function that is represented by the graph?
On a coordinate plane, a line goes through points (0, 3) and (4, 0).
The slope is the change in y over the change in x.
The first number in the parentheses is the x value, the second number is the y value.
Slope = (0-3) / (4-0)
Slope = -3/4
The y intercept is the y value when x is 0.
The given point (0,3) has x as 0, so the y intercept would be 3
Answers: slope = -3/4, y intercept = 3
Answer:
y intercept = 3 slope = -3/4
