Finding ∠BOC :

Answer:

Alrighty... i am happy that you would like an explanation.. that is truly admirable...

let's begin!!!

Step-by-step explanation:

We need to place everything into an equation to solve for x... after that we can substitute the value for x into the expression for m<BOC to get its value (i hope this isn't confusing... the math is easier though... trust me)

8X -67 +9X -75 = 96              Add 67 and 75 to both sides to isolate x

8X +9X = 238       --> 17X = 238

divide both sides by 17 to get x = 14

then subsitute x = 14 into the expression for m < BOC

you get  8(14)-67 = 45

therefore, the measure of <BOC is 45 degrees

I really hope this helps!!!!!

Revising the area of a circle formula

We already know that the area of a circle is expressed as [tex]\pi r^{2}[/tex].

We are given the radius of circle, which is 7 in. Let us substitute the radius in the formula. Once substituted, we can simplify the expression obtained to determine the area of the circle shown in the picture.

[tex]\implies \pi (7)^{2}[/tex]

Take π as 22/7

[tex]\implies \huge\text{(}\dfrac{22}{7} \huge\text{)}(7)^{2}[/tex]

[tex]\implies \huge\text{(}\dfrac{22}{7} \huge\text{)}(7)(7)[/tex]

[tex]\implies (22)(7)[/tex]

[tex]\implies 154 \ \text{in}^{2}[/tex]

In this problem, we are given the diameter to be 24 kilometers. Since the radius of the circle is half the diameter, we can tell that the radius of the circle is 24/2 kilometers, which is 12 kilometers.

[tex]\implies \pi (12)^{2}[/tex]

Take π as 22/7

[tex]\implies \huge\text{(}\dfrac{22}{7}\huge\text{)} (12)^{2}[/tex]

[tex]\implies \huge\text{(}\dfrac{22}{7}\huge\text{)} (12)(12)[/tex]

[tex]\implies \dfrac{3168}{7} \ \text{km}^{2}[/tex]

We are given the radius of circle, which is 3.5 in. Let us substitute the radius in the formula. Once substituted, we can simplify the expression obtained to determine the area of the circle shown in the picture.

[tex]\implies \pi (3.5)^{2}[/tex]

Take π as 22/7

[tex]\implies \huge\text{(}\dfrac{22}{7}\huge\text{)} (3.5)^{2}[/tex]

[tex]\implies \huge\text{(}\dfrac{22}{7}\huge\text{)} (3.5)(3.5)[/tex]

[tex]\implies \huge\text{(}\dfrac{22}{2}\huge\text{)} (3.5) = (11) (3.5)[/tex]

[tex]\implies 38.5 \ \text{m}^{2}[/tex]

Note: The radius given in this problem was not clearly stated. If the radius I stated here, is incorrect, please notify me in the comments. Thanks!

Step-by-step explanation:

To find the volume you have to multiply the base and the height which is 7 and 6 and divide it by 2.  Then you multiply the 8.  

Answer:

Yes,

Step-by-step explanation:

16/22 = 0.72727272727

24/33 = 0.72727272727

When translated into decimals, they both equal 0.72 reoccurring.

x = 0.72727272727...

10x = 7.2727272...

100x = 72.727272727...

100x - x = 90x = [tex]\frac{72}{90}[/tex] which can be translated/simplified into [tex]\frac{16}{22}[/tex] and [tex]\frac{24}{33}[/tex]

B. 1 1/8 pounds

Step-by-step explanation:

What we know:

6 Pounds of meat in total

3 1/8 pounds of ground beef

1 3/4 pounds of sausage

Combining the pounds of ground beef and sausage together:

3 1/8 + 1 3/4 = 4 7/8

In all he has 6 pounds of meat. He we know the combined weight of the ground beef and sausage combined: 4 7/8 pounds. Therefore, the equation is...

6 - 4 7/8 =

The answer is...

B. 1 1/8 pounds

Answer:

B. 1 1/8 pounds.

Step-by-step explanation:

Let the weight of turkey he bought  be x pounds.

Then we have the equation:

x + 3 1/8 + 1 3/4 = 6

x = 6 - 3 1/8 - 1/ 3/4

Converting to improper fractions

x = 6 - 25/8 - 7/4

We could use a calculator to do this but it also can be done manually by converting all amounts to fractions with denominator 8:

x =  48/8 - 25/8 - 14/8

   =  9/8

    = 1 1/8 pounds.

How to make Mixed fractions into Improper Fractions?

Easy!

What you do is, you multiply the denominator with the whole number, then add the result of multiplying the denominator with the whole number to the numerator, and then, when you have that result, you put that result as your new numerator, and the denominator remains same from the Mixed fraction.

Look at picture

Answer: V = 13.1 mph

Step-by-step explanation:

12,000 = 5.312V^3

Divide 5.312 from both sides, and on the right side it will cancel out.

12,000/5.312 = V^3

2,259 = V^3

Extract the cube roots of both sides, leaving V^3 to just V.

13.1 = V (I think)

Answer:

6. The hand already has 3 clubs and cannot have any more clubs, so we have to choose 10 cards from the remaining 39 cards of 3 suits (spades, diamonds and hearts).

Let x be the length of each side of the nonagon. We then split up the nonagon into 9 congruent, isosceles triangles, each with base = x and height = 12. Then the area of each triangle is 1/2 • x • 12 = 6x, so the total area of the nonagon will be 9 • 6x = 54x.

To find x, we can use some facts from geometry and trigonometry.

• In any polygon, the sum of the measures of the exterior angles is 360°. So each of these exterior angles will measure 360°/9 = 40°.

• Exterior angles are supplementary to the interior angles. So each interior angle will measure 180° - 40° = 140°.

• Each of the 9 triangles are isosceles with base angles measuring half the interior angles of the nonagon, 140°/2 = 70°.

• Cut the triangle in half along the labeled inradius of the nonagon, which has length 12. In the resulting right triangle, we have

tan(70°) = 12 / (x/2)

and solving for x gives

tan(70°) = 24/x

x = 24/tan(70°)

x = 24 cot(70°) ≈ 8.7

Then the total area of the nonagon is

54x = 54 • 24 cot(70°) ≈ 471.7

The population of 150,000 decreases each year by 150

  Since the population is decreasing it would be -150 iguana's

Answer: A

Step-by-step explanation:

facts

there are 150,000 iguanas. each year, we lose 150.

The rate of change is a fixed amount of something increasing or decreasing in a certain amount of time. Since the population loses 150 iguanas each year, the rate of change, or unit rate, is -150 (if it decreases, its negative).
