Ok first I need to know what number is multiplied by four and yea
Answer:
Step-by-step explanation:
True statements
All equallateral triangles are similar. Their sides are all in the same ratio when comparred.
All squares are similar. Same reason as equilateral triangles. All sides to both squares compared are the same.
False Statements
Isosceles triangles can and usually do have different base angles.
rectangles can have all sorts or side lengths. The only requirement is consecutive sides form right angles.
2 rhombuses can have side lengths that are in the same ratio, but the heights are not in the same ratio. That eleminates.
Answer
These are the only true ones: Statements 2 and 5 are true. The rest are not.
Answer: There are 97 nickels and 108 quarters.
Step-by-step explanation:
Let x = Number of nickels, y = Number of quarters.
As per given,
x+y = 205 ...(i)
0.05x+0.25y = 31.85 ... (ii) [1 nickel = $0.05, 1 quarter = $ 0.25]
Multiply (ii) by 20, we get
x+5y=637 ...(iii)
Eliminate (i) from (iii)
4y = 432
⇒ y = 108 [Divide both sides by 4]
Put value of y in (i), we get
Hence, there are 97 nickels and 108 quarters.
Answer:
7,13,37,55,103
Step-by-step explanation:
y = 5 + 2x^2
if x =1
y = 5 + 2(1)^2
1^2 = 1
2 x 1 = 2
y=5 + 2 or y = 7
you substatute each one in for x to solve for y
The answer to this is x/2 = 3.
