Pls help me with this problem. Also the answer has to be in terms of pi

Answer:

What equation...................wait nvm

Answer:

2/7

Step-by-step explanation:

-1 1/7 + 6/7 = -8/7 + 6/7 = 2/7

Answer:

cos 45 degree = A/H

cos 45 degree =  2 square root 2 / x

x = 2 square root 2 / cos 45 degree

x = 4

Sin 45 degree = O/H

Sin 45 degree = y/ 4

4 x Sin 45 degree = y

y = 2.83

or

we could use tan

tan 45 degree = O/A

tan 45 degree = y / 2 square root 2

2 square root 2 x tan 45 degree = y

y = 2.83

i hope this would elp a little bit.

Answer:

D

Step-by-step explanation:

Answer:

14.28 ft

Step-by-step explanation:

Perimeter of the shaded region = 2(side of the square) + ¼(circumference of circle)

Side of the square = 4 ft

Circumference of circle = 2πr

r = 4

Circumference = 2*π*4 = 25.1327412 ft

✔️Perimeter of the shaded region = 2(4) + ¼(25.1327412) = 14.2831853 ≈ 14.28 ft (nearest hundredth)

Answer:

7 square miles

Answer:

I think its the right shape being the trapezoid

Step-by-step explanation:

the triangle looks like a triangle but then the reason why I said I think it's the on the right is because the acute angle makes it look like a trapezoid but then on the other side it has a right angle but I think its the right side.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

4(X+5) = 144   (if on side measures (x+5)  then P will be the 4 sides added

                        so adding the same value repeatedly means multiplication.

 -  Distribute:  4x + 20 = 144

-     Inverse op. to isolate the variable minus 20 from both sides

-     4x = 124

-     Divide by 4 on both sides

-      124/4 = 31

-      x = 31 units

Answer:

a) The sample mean is 47 dollars, while the claimed population mean is 70 dollars.

b) The sample mean is 3.75, while the claimed population mean is 3.48.

Step-by-step explanation:

Question a)

American households spent an average of about $70 in 2007 on Halloween merchandise such as costumes, decorations and candy means that the claimed population mean is 70 dollars.

The survey included 2100 households and found that average Halloween spending was $47 per household means that the sample mean is 47 dollars.

The sample mean is 47 dollars, while the claimed population mean is 70 dollars.

Question b)

The average GPA of students in 2001 at a private university was 3.38 means that the claimed population mean is 3.38.

The survey yielded an average GPA of 3.75 means that the sample mean is 3.75.

The sample mean is 3.75, while the claimed population mean is 3.48.

Answer:

The formula for slope is sometimes referred to as "rise over run", because the fraction onsists of the "rise" (being the change in y, going up or down) divided by the "run" (being the change in x, going from left to the right).

Step-by-step explanation:

Answer:

Good sir/madam, in a fraction, it is always rise over run.

Answer:39

Step-by-step explanation: yes

Answer:

268

Step-by-step explanation:

Answer:

1/4

Step-by-step explanation:

Find the GCD (or HCF) of numerator and denominator GCD of 18 and 72 is 18

Divide both the numerator and denominator by the GCD 18 ÷ 18 / 72 ÷ 18

Reduced fraction: 1 / 4 Therefore, 18/72 simplified to lowest terms is 1/4.

Answer:

A) 30 in³

B) V=lwh (or) V+5x3x2

C) 3 times

Step-by-step explanation:

A) 30in³

B) V=LWH (or) V+5x3x2

C) V=[tex]\pi[/tex]r²h = [tex]\pi[/tex](2.6²)(4) = 84.94867

85.94867÷30= 2.83, so he’d need to fill the rectangular prism 3 times.

Answer:

a. 30 in³

b. V = whl

c. 3 times

Step-by-step explanation:

a. v = whl

V = (3 in)(2 in)(5 in)

V= 30 in³

b. V = whl

c. Volume of the cylinder = pi(r²)h            r = d/2 = 5.2 / 2 = 2.6

Vc = pi (2.6²)(4)

Vc ≈ 84.94 in³

84.94 in³/30 in³ ≈ 3 times

Answer:

180 degrees

Step-by-step explanation:

angle 1 = 90 degrees

angle 4 = angle 1 because they are vertical angles

360 - 90 - 90 = 180 degrees

Answer:

x ≈ 18.3°

Step-by-step explanation:

Reference angle = x

Opposite side = 11

Hypotenuse = 35

Apply SOH:

Sin x = opp/hyp

Sin x = 11/35

[tex] x = sin^{-1}(\frac{11}{35}) [/tex]

x ≈ 18.3°

Actually Welcome to the Concept of the volumes.

Here given as, r= 6.2 mm, h = 10.8 mm, π=3.14

hence, the volume of the cone is

Volume = 1/3(πr^2h)

===> vol = 1/3(3.14*(6.2)^2*(10.8))

==> Vol = 1/3*(1303.57)

==> Vol = 434.52 mm^3

Hence the volume of the cone is 434.52 mm^3

Answer:

7.5 kilograms of apples

Step-by-step explanation:

Take the total amount and subtract the amount of pears.

8.9-1.4=7.5

Answer:

If 2/5 are apples, 2/5 x 8.9 kilos = 0.4 x 8.9 = 3.56 kilos of apples

pears = 8.9 - 3.56 = 5.34 kilos

if apples are 2/5, then pears are 3/5.  3/5 x 8.9 = .6 x 8.9 = 5.34 kilos of pears
