By law of cosine we have the following equation:
b ^ 2 = 28 ^ 2 + 22 ^ 2 - 2 * 28 * 22 * cos (34)
Clearing b we have:
b = root (28 ^ 2 + 22 ^ 2 - 2 * 28 * 22 * cos (34))
Calculating we have:
b = 15.7043214
Rounding:
b = 15.7 yd
Answer:
b = 15.7 yd
option 1

A hemispherical bowl has a radius of 3.5 cm. What would be the volume of water it would contain?

kirill [66]

Answer:

89.80 cm cubed

Step-by-step explanation:

A hemisphere is essentially just half of a sphere. We want to find its volume.

The volume of a sphere is denoted by: V = (4/3)π * r³, where r is the radius. That means the volume of a hemisphere, which is half a sphere, will be denoted by: V = (1/2) * (4/3)π * r³ = (2/3)π * r³.

Here, the radius is 3.5, so plug this in:

V = (2/3)π * r³

V = (2/3)π * (3.5)³ ≈ 89.80 cm cubed

8(2x- 6)= 96 solve for x

9966 [12]

Answer:

x=9

Step-by-step explanation:

To solve, simplify the equation them isolate x.

8(2x- 6) = 96 Distribute over brackets by multiplying

16x - 48 = 96 Add 48 to both sides

16x = 144 Divide both sides by 16

x = 9 Final answer

Two consecutive integers whose product is 56

Iteru [2.4K]

≡ We know that:
⇔ Consider the first integer is $a$
⇔ So, the next integer is $(a+1)$

≡ Solution:
⇒ $(a).(a+1)=56$
⇒ $a^{2}+a=56$
⇒ $a^{2}+a-56=0$
⇒ $(a+8)(a-7)=0$
⇒ $a_{1}=-8$ ║ $a_{2}=7$

⇔ For $a=-8$
⇒ the next integer is $(a+1)=-8+1=-7$

⇔ For $a=7$
⇒ the next integer is $(a+1)=(7+1)=8$

∴ So, there are 2 options [ $\boxed{-8}$ and $\boxed{-7}$ ] or [ $\boxed{7}$ and $\boxed{8}$ ]
