Look at the table for each type of bird. 5x=15. 6x=18. 10x=30. What would you multiply each of those by to get your answer and find the difference? 5x=15; x= 3. It is the same for each number. So the difference is by 3. I think if I understand this correctly, that would be how you do it. Does this help?

Sample answer: Divide the number of robins by the number of cardinals for each pair of values. The ratios are the same and are a constant of proportionality of 3.

NARA [144]

Ratio of men:women in the simplest form is 7:8

Step-by-step explanation:

Step 1: Given total adults = 150. Number of women = 80. Find the number of men.

Number of men = 150 - 80 = 70

Step 2: Find the ratio between men and women.

What graph represents the function f(x) = 8 1/3^x?

densk [106]

Answer:

B (second graph from left)

Step-by-step explanation:

The function when x=0 will be 1 since any number to the zero exponent is 1. This means only B and D are options.

Because of the fraction, the values will be smaller and have a gentler slope. B is the solution.

Given: QR I PT and ZQPR = ZSTR

Rina8888 [55]

Answer:

$\triangle PQR \sim \triangle TSR$

Step-by-step explanation:

Given :

QR⊥PT

$\angle QPR = \angle STR$

To Prove : $\triangle PQR \sim \triangle TSR$

Solution:

Statements Reasons

QR⊥PT Given

∠QRP and ∠SRT are right angles Def of perpendicular

∠QPR≅∠STR Given

∠QRP = ∠SRT All right angles are equal

ΔPQR≈ΔTSR AA similarity

Hence $\triangle PQR \sim \triangle TSR$
