Find (a) the perimeter and (b) the area of the figure. Use 3.14 or 22 22 for 1. Round your answer to the nearest hundredth, if necessary.​

Answer:

tan B =8/15

Step-by-step explanation:

take angle B as reference angle

tan rule

tan B=opposite / adjacent

= 8/15

Tan∅ = b/h

so,

= 8/15 is your answer!

Answer:

ok so lets make a list of what days each sister will make sandwiches

Emily:4,8,12,16,20

Sister:8,16,24,32,40

from looking at this we know that they will both make sandwiches on the 8th day

Hope This Helps!!!

Answer:

B. -1

Step-by-step explanation:

it is plainly visible.

the dot is one unit to the left (x- or Real-axis), which is -1.

and it is 3 units down (y- or Imaginary-axis), which is -3.

the number is therefore -3i - 1

the question was only for the real part (without any "impact" by an "i"), which again is -1.

Answer:

6.3

Step-by-step explanation:

[tex]6^{2} + 2^{2} = x^{2}[/tex]

40 = [tex]x^{2}[/tex]

[tex]\sqrt{40} = \sqrt{x^{2} }[/tex]

x = 6.3

Answer:

6.3

Step-by-step explanation:

Pythagoras' Theorem (or Pythagorean Theorem) states a²+b²=c², where c is the hypotenuse.

We can use this equation and swap a and b for 6 and 2. This gives 6²+2²=c², which can be expanded to 36+4=c², and further c²=40.

To work out c, we need to square root both sides, leaving c=6.3245553203367586639977870888654, which rounded to 1 decimal place (nearest tenth) is 6.3.

Answer:

45

Step-by-step explanation:

an octagon has 8 sides

360/8 =45

CONNECTION

X = exterior angle of the octagon

The mistake is that it is 1/16 not 16. The person probably did the reciprocal or incorrectly used the fraction

Answer:

The exponent for the answer should be -2. Therefore, the answer will be 4⁻² or 1/16.

Step-by-step explanation:

When dividing fractions, you subtract the exponents as long as they have the same base.

Since the exponents both have the base of 4, subtract 9 - 11.

9 - 11 = -2

The exponent would be -2 and the answer would be 4⁻².

When an exponent is negative, you take the inverse of the base raised to the positive exponent.

Since 4² = 16 or 16/1, 4⁻² would be 1/16.

The answer would be 4⁻² or 1/16.

Hope that helps.

Answer:

  (-2, 5, 7)

Step-by-step explanation:

The problem statement lets us write three equations for the three numbers x, y, and z.

  x + y + z = 10

  -x + 2y = 12

  x - y + 2z = 7

__

Adding the second equation to each of the other two gives ...

  3y +z = 22

  y +2z = 19

Subtracting the second of these from double the first gives ...

  2(3y +z) -(y +2z) = 2(22) -(17)

  6y +2z -y -2z = 44 -19

  5y = 25

  y = 5

  z = 22 -3(5) = 7 . . . . . . from 3y+z=22

  x = 10 -5 -7 = -2 . . . . . .from x+y+z=10

The numbers are (x, y, z) = (-2, 5, 7).

Answer:

55

Step-by-step explanation:

since angle 35 and the arrow are parallel they are the same.

Given:

The equation is:

[tex]efg-h=i[/tex]

To find:

The value of f.

Solution:

We have,

[tex]efg-h=i[/tex]

We need to isolate f to find the value of f.

Adding h on both sides, we get

[tex]efg-h+h=i+h[/tex]

[tex]efg=i+h[/tex]

Dividing both sides by [tex]eg[/tex], we get

[tex]\dfrac{efg}{eg}=\dfrac{i+h}{eg}[/tex]

[tex]f=\dfrac{i+h}{eg}[/tex]

Therefore, the value of f is [tex]f=\dfrac{i+h}{eg}[/tex].

Answer:

h = -4

Step-by-step explanation:

3(h+6) = 2(-5-2h) Solve for h.

Apply distributive property first on both sides.

3(h+6) = 2(-5-2h)

3h+18 = -10-4h

Next, put the terms with h on one side and the numbers on the other.

3h+18 = -10-4h

7h = -28

Divide both sides by 7 and you have your answer.

7h = -28

h=-4

Answer:

-4

Step-by-step explanation:

First, expand the brackets by multiplying the left bracket all by 3 and the right all by 2. This gives 3h+18=-10-4h.

You want h all on one side, so add 4h to both sides, leaving 7h+18=-10.

Subtract 18 on both sides to leave only h and the coefficient on the left. This gives 7h=-28.

Dividing both sides by 7 isolates the x and gives h=-4.

Expressions with the correct statements will be as below.

1). (y + 2)²→ The square of the sum of 2 and y

   Correct

2). 7(6x² + 5x + 4) → The product of 7 and the sum of 6 time the square of y and 5 times x plus 4

   Incorrect

3). 7y² - 3 → The difference of 7 times the square of y and 3

    Correct

4). 5x² → Product of 5 and the square of x.

    Incorrect

5). y² + 11y + 24 → The sum of y squared and 11 times y plus 24

    Correct

6). 5(x² - 6) → 5 times the difference of the square of x and 6

    Correct

Answer:

-11xy

Step-by-step explanation:

-14xy -(-3xy)

multiply the bract first - sign * minus sign is plus sign

-14xy+3xy

since they are like terms u can subtract them.u should subtract them because minus and plus means subtract and we should put minus sign in front of the answer because 14 is the highest number and it's sign is negative .

-11xy

Answer:

The radius of the cylinder is 2.52 cm.

Step-by-step explanation:

The formula for the volume of a cylinder of radius r and height h is

V = πr²h.  We can solve this for r² by dividing both sides of the equation by πh:

r² = V / (πh)

Then the desired radius is found by taking the square root of this.

r = √{V / [πh]}

                  200 cm^2

Here, r² = ------------------- = 6.37 cm^2

                   3.14(10 cm)

and so r = √6.37 cm^2 = 2.52 cm

The radius of the cylinder is 2.52 cm.

Answer:

radius = 2.52 cm

Step-by-step explanation:

[tex]Volume = \pi r^2 h\\\\200 = \pi r^2 \times 10\\\\\frac{200}{10 \times \pi} = r^2 \\\\6.332 = r^2 \\\\\sqrt{6.332} = r \\\\r = 2.52 \ cm[/tex]

Answer:

6 hours.

Step-by-step explanation:

Here's my work.

Chang only wanted to spend $44, and the boat costs $8/hr. So, the variable would only be 8t, and you would put 44 on the other side.

Then, you'd put -4 on the side with 8t, because you can take off $4.

So, the setup would be;

44 = 8t - 4.
