Hello from MrBillDoesmath

Answer: multiply each by 1.5 to get the next term.

Discussion: I noticed that 7.5 is 1.5 times 5 -- and 5 is the first number in the sequence. I wondered if that was the pattern so I used Calc to multiply 7.5 by 1.5 and got 11.25. (Looking good). Then I multipled 11.25 by 1.5 and got 16.875.

Regards,

MrB

Answer:

The first one: 19/15a

second one: b²-4ac = D

Step-by-step explanation:

for first one: take LCM and solve

for second one: you square the expression on both sides then b²= D + 4ac, then when you take 4ac to the left hand side, it becomes b²-4ac= D

an architect wants to build three similar triangles such that the ratio of the middle triangle. The smallest one has side length

vampirchik [111]

Answer: 15

<u>Step-by-step explanation:</u>

small: 5 12 13

middle: __ 36 39

large: 45 108 117

Notice that to get from the small to the large, multiplied by 9

5(9) = 45 12(9) = 108 13(9) = 117

That is because the sides are proportional $\dfrac{5}{45}=\dfrac{12}{108}=\dfrac{13}{117}\rightarrow\dfrac{1}{9}$

To get from small to middle, multiply by 3

5(3) = 15 12(3) = 36 13(3) = 39

To solve it using proportions:

$\dfrac{5}{x}=\dfrac{12}{36}\\\\\\\text{Cross Multiply and solve for x:}\\5(36)=12x\\\\\dfrac{5(36)}{12}=x\\\\5(3)=x\\\\\large\boxed{15}=x$

43 tens × 3 tens = how many hundreds

ladessa [460]

43 tens = 43 * 10 = 430
3 tens = 3 * 10 = 30

430 x 30 = 12900 tens
12900/100 = 129 hundreds <===
