Answer:

Perimeter = 28.8 inch

Step-by-step explanation:

Step 1: Change given centimeters into inches according to the scale

2.5 / .5 = 5 <--- length in inches

4.7 / .5 = 9.4 <--- width in inches

^^^This is the same thing as multiplying 2.5 cm and 4.7 cm by two. You could also reword the scale to be 1 cm = 2 inch if it makes more sense for you

Step 2: Find the perimeter using the formula: P = 2L + 2W

2 (5) + 2(9.4)

10 + 18.8

The functio p(x)= x(x-5)(x-2)(x+3) has four zeros. What is the smallest zero.
loris [4]

Answer:

x = 5 or x = 2 or x = 0 or x = -3 thus 0 is the smallest root

Step-by-step explanation:

Solve for x:

x (x - 5) (x - 2) (x + 3) = 0

Split into four equations:

x - 5 = 0 or x - 2 = 0 or x = 0 or x + 3 = 0

Add 5 to both sides:

x = 5 or x - 2 = 0 or x = 0 or x + 3 = 0

Add 2 to both sides:

x = 5 or x = 2 or x = 0 or x + 3 = 0

Subtract 3 from both sides:

Answer: x = 5 or x = 2 or x = 0 or x = -3

Please help me!! This is math 7th grade
Musya8 [376]

Answer:

14) false

15) false

Step-by-step explanation:

14) 120% of a positive whole number is always greater than the number. If the number is 1, 120% of it would give us 1.2 which is greater than 1. However if the number is a negative whole number, 120% of it would give us a smaller number. Let's try -1. 120% of -1 would give us -1.2, which is smaller than -1. Hence the statement is false.

15) 0.5% of a number is 0.5/100 of the number so we should multiply the number by 5/1000. 5/100 is only 5% of the number. Hence the statement is also false.

A rectangular prism measures 225 inches by 315 inches by 2 inch.
Bas_tet [7]

Answer:

No I don't agree with Priya

The reason why I don't agree with Priya is because 25 Inch side blocks are BIGGER than 15 inch side blocks. That means that it will take less amount of 25 inch side blocks to fill up the volume of the rectangular prism rather than 15 inch side blocks.

(I'm sorry, I don't know what was your previous question, so I can't answer that part. If you comment it below, I will do it!)
