Evaluate the expression when b=-5 and c=7
b-3c

Answer:

38.1 cm²

Step-by-step explanation:

area of full circle = π6² = 113.04 cm²

area of 150° segment = (150/360)(113.04) = 47.1 cm²

triangle base = sin 75° x 6 x 2 = 11.59

triangle height = cos 75° x 6 = 1.553

area of triangle = 1/2(11.59)(1.553) = 9 cm²

150° segment - triangle = 47.1 - 9 = 38.1 cm²

x = 2

y = 1

Explanation:

Check the image

Answer:

(2,1)

Step-by-step explanation:

Since we already have an equation for y, all we need to do is plug that into y in the other equation.

y + 5 = 3x

(2x - 3) + 5 = 3x

2x - 3 + 5 = 3x

2x + 2 = 3x

2 = x

Now that we know y, we just need to plug the value of x into the equation.

y = 2(2) - 3

= 4 - 3

= 1

Answer:

(x, y) --( 3/2x, 3/2y)

Answer:

A = 4.6 cm

Step-by-step explanation:

Here, we want to find the length of the apothem, given the side lengths

Mathematically, we have this as;

A = s/2 tan (180/n)

where in this case;

s is the length of the sides which is 16 cm

n is the number of sides (since it is hexagon, we have this as 6)

Substituting these values;

A = 16/2 * tan (180/6)

A = 8 * tan 30

A = 4.62

To the nearest tenth, A is 4.6 cm

Answer: disagree with both.

Step-by-step explanation:

Answer:

D.)

No. There are only 12 bolts that have lengths greater than 1 inch, which is not enough.

Step-by-step explanation:

Based on information provided by the dot plot above, we can deduce that the number of bta longer Than 1 inch are those with length ; 1 1/8, 1 3/8, 1 4/8

Counting the number of these bolts :

1 1/8 = 5 bolts

1 3/8 = 3 bolts

1 4/8 = 4 bolts

Hence, total number of bolts longer Than 1 inch :

(5 + 3 + 4). = 12 bolts

The number of bolts longer than 1 inch is 16. Therefore, he does not have enough bolt for the project.

Answer:

-0.38%

Step-by-step explanation:

Divide 31 by 50. 31 / 50 = 0.62.

1 - 0.62 = 0.38

Since it is a decrease in change the percent change is negative.

-0.38%

Answer:

7 inch

Step-by-step explanation:

AC= BC+AB

= (BD-CD) + radius of B

= (radius of B-radius of D) + 4.5

=(4.5-2) +4.5

=2.5+ 4.5

=7 inch

I hope this is correct.

Answer:

100m^2

Step-by-step explanation:

square has equal sides.

To find the area of the square, the formula is:

Area= length times width

Answer:

yes it is I but smaller in size

Answer:

x = 2

Step-by-step explanation:

-8(x-6) = 32 (distribute)

-8x+48 = 32 (subtract 48 from both sides)

-8x = -16 (divide)

x = 2

Answer:

x = 2

Step-by-step explanation:

Divide both sides :

−8(x−6)=32

Divide both sides of the eqaution by -8 :

x - 6 = -4

Move the constant to the right :

x - 6 = -4

Move the constant to the right - hand side and change its sign :

x = -4 + 6

Calculate :

x = -4 + 6

Calculate the sum :

x = 2

Therefore, the answer is x = 2

Answer:

The answer would be P(x) = 1573*(1.02)^x

The length of the side would be sqrt(77) = 8.7749.....

This can be classified as two answers:

A and D

This is a real number

It is also an irrational number because it can’t we written as a simple fraction.

Answer:

the most I have ever felt fear of someone was ar a local gas station or my job lol but basically I was working behind the register and this couple comes in and looks pretty sus but I don't think much of it so I greet them and scan all their items and right as I bag their stuff, the wife literally takes the bag, swings it around, and knocks me out and then they run off with their stuff. So I was left there unconscious for about a hour before the next customer came and called the police. I haven't nessecarily gotten over that fear yet but I do have a glock now.

[tex]$\frac{1}{3}$[/tex] , 0.33 , 33%

Step-by-step explanation:

The spinner has 4 green, 4 blue and 4 yellow.

So total = 12

Therefore, the probability of the spinner landing on blue or green as a fraction is = [tex]$\frac{4}{12}$[/tex]

   [tex]$=\frac{1}{3}$[/tex]

The probability of the spinner landing on blue or green as a decimal is = 0.33

The probability of the spinner landing on blue or green as a percent is

= 0.33 x 100

= 33 %

Answer:

731,100

7.311 × 10^5

Step-by-step explanation:

The computation of the number of sheet used by other department is given below:

Given  that

The company used 7.4 × 10^5 sheets of paper So it would be 740,000  

And, The accounting department used 8.9 × 10^3 sheets so it would be 8,900  

Now the number of sheet used by other department is

= 740,000 - 8,900

= 731,100

= 7.311 × 10^5

Step-by-step explanation:

Good luck , hope it helped you :)

Answer:

58 degrees

Step-by-step explanation:

Since a straight line is 180 degrees then we can find out the two missing angles within the triangle.

180-126=54

180-112=68

54+68=122

180-122=58

m=58 degrees

Hope this helps :)

Answer:

6/36 or 1/6

Step-by-step explanation:

To find the probability of rolling a number greater than 4, then rolling an odd number, you must multiply the probability of rolling numbers greater than 4 by the probability of rolling an odd number. In numbers 1-6, there are two number greater than 4: 5 and 6. The probability of an event is the specific factor over the total amount of results or objects. The probability of rolling a number higher than 4 is 2/6, or 1/3. In numbers 1-6, there are 3 odd numbers: 1, 3, and 5. The probability of rolling an odd number is 3/6, or 1/2. 3/6 times 2/6 is 6/36, and when simplified, it becomes 1/6.

Answer:

x = 15

Step-by-step explanation:

37*2 = 74

360-74 = 286

286 = 2(9x + 8)

143 = 9x+8

135 = 9x

15 = x

Answer:

50%

Step-by-step explanation:

Since 1,000 is 100% of the attendance, 500 is half of 1,000 meaning it's 50%.

I think the student added 50% and 100%, they could have also divided 1,500 by 10.

The actual percent increase would be equal to 50 percent.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means). Thus, that thing in number is [tex]\dfrac{a}{100} \times b[/tex]

We have been given that the Average attendance at a school’s basketball games increased from 1,000 to 1,500 last year. a student said that represented a 150% increase.

Since 1,000 is 100% of the attendance, 500 is half of 1,000 which means that it's 50%.

The student added 50% and 100%, they could have also divided;

1,500 by 10

Therefore, the actual percent increase would be equal to 50 percent.
