Answer:

$\boxed{ 15}$

Step-by-step explanation:

→ We know that on the right side the length of the 2 sides is 18 and one of them is 10 so,

18 - 10 = 8cm is the length of the line above 10cm

→ Now we use scale factor enlargement, we can see that opposite 12 is 8 so the multiplier that was used to get from 12 to 8 is,

12 ÷ 8 = 1.5

→ Now we know the multiplier is 1.5 and we need to find the side opposite 10 so we multiply 1.5 by 10 to get,

1.5 × 10 = 15

Answer: 15

Step-by-step explanation:

Set up the proportion as follows:

$\dfrac{18}{10}=\dfrac{12+x}{x}\\\\\\18x=10(12+x)\\\\\\18x=120+10x\\\\\\8x=120\\\\\\x=\dfrac{120}{8}\\\\\\x=\large\boxed{15}$

8. Patrice and Don buy a home for $92,000. The property tax rate is$39.50 per $1,000 of assessed value. The assessment rate is 4

Kaylis [27]

We start by calculating the assessed value, that is 41% of the price.

The price is $92,000.

Then, the assessed value is:

$AV=a\cdot P=\frac{41}{100}\cdot92000=0.41\cdot92000=37720$

The property tax rate is $39.50 per $1000 of assessed value, so we can express this rate as:

$\text{tax rate}=\frac{39.50}{1000}=0.0395$

We then can multiply this rate by the assessed value to calculate the total property tax:

$\text{tax}=0.0395\cdot37720=1489.94$

NOTE: we could have also multiplied 39.50 by 37.72. The value 37.72 is the thousands of dollars of assessed value. We would have obtained the same result: 39.50*37.72=1489.94.

Answer: the property tax is $1,489.94.

if you’re good with set theory in math 30 please help with questions 31 and 32!! real answers only !!

GREYUIT [131]

Answer: 31) d 32) c

Step-by-step explanation:

31)

A = {1, 3, 5, 15}

B = {2, 3, 5, 7}

A ∪ B = {1, 2, 3, 5, 7, 15}

C = {2, 4, 6, 8}

(A ∪ B) ∩ C = {1, 2, 3, 5, 7, 15} ∩ {2, 4, 6, 8} = {2}

2 is the only number in both sets

32)

The pattern is: reflection, add symbol, ..., reflection, add symbol.

The last image shown is: add symbol

So the next image will be: reflection (flipped to the left)

The answer is B, 5+7=12. You can also just subtract 5 from 12 and that’ll also give you the answer
