Mr. Ford Invested $12,450 in a bank at 7.25% per annum simple interest for 6 years. calculate the interest he was paid
Answer:
If my calculations are correct, $5415.75 of interest was paid throughout 6 years.
Step-by-step explanation:
7.25% of 12,450 is 902.625.
If the interest being paid was the 7.25% of 12,450 throughout the 6 years then the answer is 902.625 x 6 ( the amount of years ) = $5415.75.
In other cases such as 7.25% of the new number of invested money after the loss of 902.625 then this answer is wrong, but I solved as I understood.
Hope this helps.

Use the Law of Cosines to solve the problem.
A ship travels due west for 83 miles. It then travels in a northwest direction for 111 miles and ends up 165 miles from its original position. To the nearest tenth of a degree, how many degrees north of west did it turn when it changed direction? Show your work.
Answer: [tex]64.2^{\circ}[/tex]
Step-by-step explanation:
According to the cosine rule
[tex]\cos C=\dfrac{a^2+b^2-c^2}{2ab}[/tex]
Here, [tex]a=83, b=111, c=165,\ C=180^{\circ}-\theta[/tex]
Putting values
[tex]\Rightarrow \cos (180^{\circ}-\theta)=\dfrac{83^2+111^2-165^2}{2\times 83\times 111}\\\\\Rightarrow \cos(180^{\circ}-\theta)=\dfrac{6889+12321-27225}{18426}\\\\\Rightarrow \cos(180^{\circ}-\theta)=\dfrac{-8015}{18426}=-0.4349\\\\\Rightarrow 180^{\circ}-\theta=\cos^{-1}(-0.4349)=115.77^{\circ}\\\Rightarrow \theta=64.23\approx 64.2^{\circ}[/tex]
So, the ship turns by [tex]64.2^{\circ}[/tex] north of west
The ship turned an at angle of 64.2 degrees north of west
Represent the angle, the ship turned due north of west with theta.
From the figure, we have the following equation
[tex]\cos(A) = \frac{b^2 + c^2 - a^2}{2bc}[/tex]
So, we have:
[tex]\cos(A) = \frac{83^2 + 111^2 - 165^2}{2 * 83 *111}[/tex]
Evaluate the expression on the right-hand side
[tex]\cos(A) = -0.4350[/tex]
Take the arc cos of both sides
[tex]A = \cos^{-1}(0.4350)[/tex]
[tex]A =115.8^o[/tex]
The value of theta is then calculated as:
[tex]\theta = 180 -A[/tex]
This gives
[tex]\theta = 180 -115.8^o[/tex]
[tex]\theta = 64.2^o[/tex]
Hence, the ship turned an at angle of 64.2 degrees north of west

The youth soccer team is fundraising by washing cars. They paid $84.55 for supplies. If
they charge $8.00 per wash, how many cars must be washed to profit at least $300.00 dollars?
Answer:
The soccer team must wash 49 cars in order to gain at least $300.
Step-by-step explanation:
The soccer team started out by paying $84.55. They charge $8 per car wash. So let's say how many cars they washed was x. They need to gain at least $300 dollars. If we put this in an equation it looks like this (we are solving for x):
8x - 84.55 >or= 300
To find x we have to do the following steps:
8x - 84.55 >= 300
+ 84.55 + 84.55
8x >= 384.55
/8 /8
x >= 48
Now we have to make sure that this is correct:
8 * 48 - 84.55 = ?
384 - 84.55 = 299.45
Since 299.45 is less than 300, x must be greater than 48, but since 299.45 is so close to 300, my educated guess would be that x=49.
8 * 49 - 84.55 = ?
392 - 84.55 = 307.45
Since 307.45 is greater than 300, x=49. So we can conclude that they must wash 49 cars to profit at least $300.

Can the following side measures form a triangle?

I a) Yes
b) No
Answer:
No
Step-by-step explanation:
the sum of the two shorter sides must be greater than the longer side
(not even if it is equal to, as in this case)
Here are some formulas to see if 3 sides can make a triangle...
[tex]a+b>c\\b-a, a-b<c\\a+c>b[/tex]
So a=3
b=5 and c=8
3+5=8
So no it can't.
Gavin is measuring strips of craft wood for a geometry project. He needs 42 feet of wood. He has 11 23 yards. How many more yards of wood does he need?
Answer:
2 1/3 yards
Step-by-step explanation:
Total length of wood needed = 42 feet
Convert feet to yards
1 feet = 0.333333 yards
42 feet = 14 yards
He has 11 2/3 yards.
How many more yards of wood does he need?
= 14 yards - 11 2/3 yards
= 14 - 35/3
= (42-35)/3
= 7/3
= 2 1/3 yards
He needs 2 1/3 yards more yards of wood

Answer: 20.28 cm^2
Explanation:
First find the area of the square!
7 x 2 = 14
then find the area of the circle!
We know that the DIAMETER of the circle is 4 because the total length of the square is 7 cm and there are 3cm of length on the sides of the circle
so 7-3 = 4
Then to find the area of a circle you need to use this formula:
r = radius
A = 3.14r^2
3.14(2)^2 = 12.57
Then you need to divide it by TWO because its a half circle!
12.57 / 2 = 6.285
14 + 6.285 = 20.28 cm^2

If a car has tires with a diameter of 28 inches and is traveling at 55 mph, how fast are its tires spinning, in rpm^ prime s (revolutions per minute)? [There are 63,360 inches in 1 mile) Round your final answer to 2 decimal places .
Answer:
The tires are spinning at 660.49 revolutions per minute.
Step-by-step explanation:
The speed of the tires (v) is the same that the speed of the car, so to find the angular velocity of the tires we need to use the equation:
[tex] \omega = \frac{v}{r} [/tex]
Where:
r: is the radius of the tires = d/2 = 28 inches/2 = 14 inches
[tex]\omega = \frac{55 mph}{14 inches*\frac{1 mile}{63360 inches}} = 2.49 \cdot 10^{5} \frac{rad}{h}*\frac{1 h}{60 min}*\frac{1 rev}{2\pi rad} = 660.49 rpm[/tex]
Therefore, the tires are spinning at 660.49 revolutions per minute.

If you look carefully at these two shapes, you will notice that the first one is just an upside-down version of the second one. The question also states that these two shapes are congruent, meaning that they are the exact same shape. To figure out the measure of angle U, you must simply flip the first shape right-side up. You can either do this in your mind or on paper. To do it on paper, just draw the shape then rotate the paper until the shape looks identical to the other shape. Once you do this, you will see that angle G is the same as angle U. Their angle measurements be the same as a result.
I hope this makes sense. Please let me know if there is any other way I can help you. Good luck!
