Answer:

the answer is 216 sq cm.

Step-by-step explanation:

Do 12×14=168. Then 12×8=96. Then 96/2=48. Then add 168+48=216.

Answer:

216

Step-by-step explanation:

12x 14=168

8x12=96

96/2=48

168+48=216

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

Step-by-step explanation:

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

Answer:

the surface area of the pyramid is 62.4 square centimeters

Step-by-step explanation:

The computation of the surface area of the pyramid is shown below:

As we know that

The surface area = 2bh

= 2 × 6 cm × 5.2 cm

= 62.4 square centimeters

Hence, the surface area of the pyramid is 62.4 square centimeters

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.

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.

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

I hope this helped!

Why are you spamming questions

Step-by-step explanation:

Answer:

113°

Step-by-step explanation:

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!

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.
