Answer:

No, size increases by a factor of four

Step-by-step explanation:

for example, a square with four side lengths of two. The area of this square is 4, because 2 x 2 = 4

if we double the side lengths to 4 instead of two, the area will be 16 because 4 x 4 = 16

so no, the area increases by a factor of 4.

Answer:

No the area should not double

Step-by-step explanation:

an example given an area where length is 6 and so is the width

6x6=36

double that

12×12=144

144/2=72

72=/=36

Plz help , due in 5 mins

Grace [21]

Answer:

option a) 30 : 19

Step-by-step explanation:

$Length = 7 \frac{1}{2} = \frac{15}{2}\\\\Width = 4\frac{3}{4} = \frac{19}{4}$

Ratio of length to width:

$\frac{15}{2} : \frac{19}{4}$

$=\frac{\frac{15}{2}}{\frac{19}{4}}\\\\=\frac{15}{2 } \times \frac{4}{19}\\\\=15\times \frac{2}{19}\\\\=\frac{30}{19}\\\\30 : 19$

After 6 months, the total cost of Tanya’s gym membership was $200. After 8 months, the total cost was $260. Is this a proportion

ycow [4]

Answer:

Non-proportional; the rate of change is $30/month

Step-by-step explanation:

After 6 months, the total cost was $200.

After 8 months, the total cost was $260.

Find the rate of change using formula

$\dfrac{f(b)-f(a)}{b-a}$

Hence,

$\text{Rate of change}\\ \\=\dfrac{\$260-\$200}{8-6}\\ \\=\dfrac{\$60}{2}\\ \\=\$30\ \text{per month}$

At this rate, after 6 months Tanya paid

$\$30\cdot 6=\$180$

But after 6 months, the total cost of Tanya’s gym membership was $200.

It means the relationship passes through the point (0,20), not through the origin. Each proportional realtionship passes through the origin. Thus, this is not proportional relationship.

Estimate the weight of 6 apples.

KengaRu [80]

The answer: 1533 g {"grams"} ; or even "1530 g" or "1500 g" ; would be an acceptable estimate.
_______________________________________________________
Note: We are asked to: "Estimate the weight of 6 (six) apples."

Given: (from the table—within the image attached):
_______________________________________________________
"2 apples weigh "511 g" ;

"then "6 apples" would weigh about 3 times that weight; since:

"2 apples; multiplied by "3" , is "6 apples" .

so: "511 g * 3 ≈ 500 g * 3 = 1500 g ".

or:
"511 g * 3 ≈ 510 g * 3 = (500 g * 3) + (10 g * 3) = (1500 + 30) g = 1530 g.

or:

"511 g * 3 ≈ 511 g * 3 = (500 g * 3) + (11 g * 3) = (1500 + 33) g = 1533 g.
______________________________________________________
Note: The table shows that the given numbers of apples, along with their respective weights, are not [evenly and equally] proportional —reflecting the fact that there is variation among weight in apples across the board.
