This is a 2 part question. 

Milli has $100 to spend and pays for the room first. $100 - $40 = $60 to pay for meals.

Each meal is $12 - how many meals can she buy with $60? 

60 / 12 = 5 meals 

So Milli and 5 friends can be at the party. 

To check: 5($12) + $40 = $100

The area of a triangular block is 49 square inches. If the base of the triangle is twice the height, how long are the base and t
andrezito [222]
1) Formula: area = height * base / 2

2) Call x the height:

height = x

base = 2x

3) State the equation:

(x)(2x) = 49 in^2

4) Solve the equation:

2x^2 = 49 in^s

x^2 = (49/2) in^2

x = √(49/2) in

x = 7√2 / 2 in = 3.5 √2 in

5) Solution:

height = 3.5 √2 in and base = 7√2 in

6) Verification: area = (7√2 in) (3.5√2 in) = 49 in^2

Answer: height = 3.5√2 in and base = 7√2 in.

Simplify the expression by combining like terms. <br><br>4y+7x- 2y+4x​
juin [17]

Hello!

Answer:

\boxed{2y+11x}

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

<em>First, you switch sides. *Group like terms*</em>

4y-2y+7x+4x

<em>Then, you add the similar to elements. You can also add the numbers from left to right.</em>

4y-2y=2y

2y+7x+4x

7x+4x=11x

\boxed{2y+11x}\checkmark, is the correct answer.

Hope this helps!

Have a nice day! :)

PLEASE HELPPPP
Studentka2010 [4]

Answer:

1774.67π mm³

Step-by-step explanation:

Please find attached to this question, the required diagram.

From the question, we are told we have a spherical mold.

We would find the volume of a spherical mold using the formula for the volume of a sphere.

The volume of a sphere is calculated as : 4/3πr³

From the attached diagram, we are given the Diameter do the spherical mold as: 22mm

Radius of the spherical mold = Diameter ÷ 2 = 22mm÷ 2 = 11mm

The volume of the spherical mold = 4/3 × π × 11³

= 1774.6666667π mm³

Approximately and leaving it in terms of pi (π)= 1774.67π mm³
