Answer:

4 years

Step-by-step explanation:

Interest (I) = $ 100

r = 3.8 %

P = $ 700

t = ?

t = \frac{I *100}{P*r}\\\\t = \frac{100 * 100}{700 * 3.8}\\\\t = \frac{100 * 100}{70 * 38}\\\\t = 3.75

t = 4 years

Find the area of this figure. Round your answer to the nearest hundredth. Use 3.14 to approximate Pi.
taurus [48]

Answer:

 26.13ft^2

Step-by-step explanation:

Step  1 - As both triangles have lengths the same size, they both add together to equal a rectangle. Therefore:

4 x 3 = 12

Which is the area of the triangles.

Step 2 - Calculating the area of a circle uses the formula:

\pi r^2

Where r is the radius of the circle.

Plug the known variables in:

\pi \cdot 3^2\\\pi \cdot 9\\3.14 \cdot 9 = 28.26\\

However, this is the area of a full circle. The figure is only half a circle so we must divide this by two:

28.26 ÷ 2 = 14.13

Now, add the area of the semi-circle to the area of the triangles:

14.13 + 12 = 26.13

Therefore, the area of the figure is 26.13ft^2.

Hope this helps!

Put answer in coordinate form: 2x - 3y = 12 and x + 3y = 6
Vesna [10]
2x -3y = 12;
x + 3y  = 6;
__________(+)
3x        = 18;
x = 18÷3;
x = 6;

Then, 3y = 6 - 6;

3y = 0;

y = 0÷3;

y = 0;

William is going to the amusement park, where he has to pay a set price of admission and another price for tickets to go on each
Mice21 [21]

The point (1, 20) means that the total money spent for purchasing one ticket is $20.

<h3>Linear equation</h3>

Linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let y represent the total money spent for buying x number of tickets.

The point (1, 20) means that the total money spent for purchasing one ticket is $20.

Which triangle congruence postulates can be used to prove that Triangle ABD is congruent to Triangle CDB in Rectangle ABCD?
kramer

Answer:

SSS, SAS, ASA, AAS, HL

Step-by-step explanation:

1. SSS (side side side) says if 3 sides of one triangle are congruent to 3 sides of another triangle, then the 2 triangles are congruent.

2. SAS (side angle side) says if 2 sides and the included angle of a triangle are congruent to 2 sides and the included angle of another triangle, then the 2 triangles are congruent.

3. ASA (angle side angle) says if 2 angles and the included side of a triangle are congruent to 2 angles and the included side of another triangle, then the 2 triangles are congruent.

4. AAS (angle angle side) says if 2 angles and the none included side of one triangle are congruent to the corresponding parts of another triangle, then the 2 triangles are congruent.

5 HL (hypotenuse leg) says if 2 right triangles that have a congruent hypotenuse and a corresponding congruent leg, then the 2 triangles are congruent.

Because it is a rectangle, the sides are equal, and they share the same hypotenuse.
