$10,000 compounded every 2 years with a 10% interest rate. How much will this be worth in 10 years
$110,000
I got this answer from multiplying 10,000 by 10 then adding 10% of 10,000 (which is one thousand) 10 times, which got me an additional 10,000, and that's how I got my answer. Please comment on this answer and tell me if it is wrong, I really hope it isn't wrong. I also hope this helps you on your way, have a great day!
SU and VT are chords that intersect at point R. A circle is shown. Chords S U and V T intersect at point R. The length of S R is x + 6, the length of R U is x, the length of V R is x + 1, and the length of R T is x + 4. What is the length of line segment VT? 4 units 8 units 13 units 14 units
Answer:
13unitsStep-by-step explanation:
If SU and VT are chords that intersect at point R, then;
SR/RT = VR/RU and VT = VR + RT
Given the following
SR= x+6
RU = x
VR = x+1
RT = x+4
Substitute into the expression above;
x+6/x+4 = x+1/x
Cross multiply
x(x+6) = (x+1)(x+4)
Expand
x^2+6x = x^2+4x+x+4
x^2+6x = x^2+5x+4
x^2 will cancel out from both sides
6x = 5x+4
6x-5x = 4
x = 4
Get VT
VT = VR + RT
VT = x+1 + x+4
VT = x+x+1+4
VT = 2x+5
Since x = 4
VT = 2(4) + 5
VT = 8+5
VT= 13 units
Hence the length of the line VT is 13units

A town total allocation for firefighters wages and benefits in a new budget is $600,000. If wages are calculated at $40,000 per firefighter and benefits at $20,000 per firefighter. How many firefighters can the town employ if they spend their whole budget?
Answer:
Number of firefighters= 10
Step-by-step explanation:
Giving the following information:
Total budget= $600,000
Wage per firefighter= $40,000
Benefits per firefighter= $20,000
To calculate the number of firefighters that the town can employ, we need to use the following formula:
Number of firefighters= total budget / total cost per firefighter
Number of firefighters= 600,000 / (40,000 + 20,000)
Number of firefighters= 10

Write an equation for the data in the table. Identify your variables.
First find the slope m. slope formula: [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
Let's use (0, -20) for x1 and y1; and (2, 10) for x2 and y2
[tex]\frac{10-(-20)}{2-0}[/tex] = [tex]\frac{30}{2}[/tex] = [tex]15[/tex]
Now find the y-intercept: the point where the graph crosses the y-axis. The y intercept always has an x value of 0. So -20 is the y-intercept
Use the slope formula [tex]y = mx + b[/tex]. Slope=m, y-intercept = b
y = 15x - 20
y is the money in the bank account in dollars
x is the day

im just looking for 25/4 (that's a fraction) divided in 3.
Answer:
[tex] \frac{25}{12} [/tex]
Step-by-step explanation:
1) Use this rule: a ÷ b/c = a × c/b.
[tex] \frac{25}{4} \times \frac{1}{3} [/tex]
2) Use this rule: a/b × c/d = ac/bd.
[tex] \frac{25 \times 1}{4 \times 3} [/tex]
3) Simplify 25 × 1 to 25.
[tex] \frac{25}{3 \times 4} [/tex]
4) Simplify 3 × 4 to 12.
[tex] \frac{25}{12} [/tex]
Therefor, the answer is 25/12 and in decimal form it would be, 2.083333.

How do you find the y-intercept of a line if you have the slope and a point? Describe the steps in order.
Using the "slope-intercept" form of the line's equation (y = mx + b), you solve for b (which is the y-intercept you're looking for). Substitute the known slope for m, and substitute the known point's coordinates for x and y, respectively, in the slope-intercept equation. That will let you find b.
Hope that helps!!!!
Answer:
it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis.

4kg of cheese costs £10.80 how much would 3kg cost
Answer:
£8.10
Step-by-step explanation:
Divide £10.80 by 4 to find the cost of 1 Kg, then multiply this by 3
£10.80 ÷ 4 = £2.70 ← cost of 1 Kg , then
cost of 3 Kg = 3 × £2.70 = £8.10
Answer:
it may helps......
Step-by-step explanation:
we can solve it by unitary method....So,
Cheese (in Kg). Cost (in Rs)
4kg 10.80
3kg X
Now, 4×x = 3×10.80
X=3×10.80/4 (by transposing)
X=2.7×3
X= 8.1 Answer

Answer:
[tex]\sin Y= \frac{XZ}{XY}[/tex]
[tex]\cos Y= \frac{YZ}{XY}[/tex]
[tex]\tan Y= \frac{XZ}{YZ}[/tex]
Step-by-step explanation:
Given
See attachment for triangle
Required
Find [tex]\sin, \cos[/tex] and [tex]\tan[/tex] of angle Y
For angle Y:
[tex]Opposite = XZ[/tex]
[tex]Adjacent = YZ[/tex]
[tex]Hypotenuse = XY[/tex]
The [tex]\sin[/tex] of an angle is calculated as:
[tex]\sin\theta = \frac{Opposite}{Hypotenuse}[/tex]
So:
[tex]\sin Y= \frac{XZ}{XY}[/tex]
The [tex]\cos[/tex] of an angle is calculated as:
[tex]\cos\theta = \frac{Adjacent}{Hypotenuse}[/tex]
So:
[tex]\cos Y= \frac{YZ}{XY}[/tex]
The [tex]\tan[/tex] of an angle is calculated as:
[tex]\tan\theta = \frac{Opposite}{Adjacent}[/tex]
So:
[tex]\tan Y= \frac{XZ}{YZ}[/tex]

What is the product?
(9t - 4)(-9 t - 4)
negative 81 t squared minus 16
negative 81 t squared + 16
negative 81 t squared minus 72 t + 16
negative 81 t squared + 72 t + 16
Answer:
The product is -81 t² + 16
Step-by-step explanation:
The product of two binomials (ax + b)(cx + d), where a, b, c, and d are constant
Multiply (ax) by (cx) ⇒ 1st × 1st
Multiply (ax) by (d) and (b) by (cx) ⇒ ext-reams and nears
Add the two products ⇒ like terms
Multiply (b) by (d) ⇒ 2nd × 2nd
Let us find the product of (9 t - 4) and (-9 t - 4)
Multiply the 1st two terms
∵ (9 t)(-9 t) = -81 t²
Multiply the ext-reams
∵ (9 t)(-4) = -36 t
Multiply the nears
∵ (-4)(-9 t) = 36 t
Add the like terms
∵ -36 t + 36 t = 0
Multiply the 2nd two terms
∵ (-4)(-4) = 16
Write the answer
∴ (9 t - 4)(-9 t - 4) = -81 t² + 0 + 16
∴ (9 t - 4)(-9 t - 4) = -81 t² + 16
The product is -81 t² + 16
