Solution:
Given:
[tex]2:5 = x:20[/tex]
We know that:
Since the LHS and the RHS are equal, they form a proportion[tex]\text{a:b} = \text{c:d} \rightarrow \text{ad} = \text{bc}[/tex]To find x, let's multiply the extremes and put the product on one side. Then multiply the middles and put the product on the other side.
⇒ [tex]2:5 = x:20[/tex]⇒ [tex]2 \times 20= x \times 5[/tex]Now, solve for x.
⇒ [tex]2 \times 20= x \times 5[/tex]⇒ [tex]40 = 5x[/tex]⇒ [tex]\frac{40}{5} = \frac{5x}{5}[/tex]⇒ [tex]\boxed{x = 8}[/tex]Two identical rectangular prisms and two identical cubes are joined. Answer the questions to find the new solid’s surface area. The numbers are 9 and 4
Answers
The surface are of the new solid formed by the joining of two identical cubes having a surface area of 294 cm² is: 490 cm²
What is the Total Surface Area of a Cube?Total surface area of a cube = 6a², where a is the length of each of the sides.
Given:
Surface area of each identical cube = 294 cm²
Find the length of each side:
6a² = 294
a² = 294/6
a² = 49
a = √49
a = 7 cm
Surface area of the new solid = surface area of the two identical cubes - 2(area of the surface where both are joined)
Surface area of the new solid = 2(294) - 2(7²) = 490 cm²

The first number is the x-coordinate, the horizontal distance from the y-axis. The second number is the y-coordinate, the vertical distance from the x-axis. Positive numbers indicate "right" or "up". Negative numbers indicate "down" or "left."
A)The mark is 3.5 units left of the y-axis and 4 units down from the x-axis.

At the market, Joey buys 3 avocados for $0.40 Each and 5 lemons for $0.40 each. The cashier in training rings up 3x0.40 and then 5x0.40 to get the total. The experienced cashier says to add the 3 plus 5 in his head and then ring up 8x0.40. What property says that these two totals would be the same
Answers
Answer:
Distributive property
Step-by-step explanation:
Distributive property states that,
multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
That is,
a(b + c) = ab + ac
3 avocados cost $0.40 each
3x0.40
= $1.2
5 lemons cost $0.40 each.
5x0.40
= $2
Total = $1.2 + $2
= $3.2
Using distributive property
(3+5)0.40
= 8(0.40)
= $3.2
Answer: Distributive property
Step-by-step explanation:
The Distributive property is the same as a(b + c) = ab + ac
