Answer:

-23

Step-by-step explanation:

As I increases by 18, y decreases by 12. From the last value in the table, I needs to increase by 2·18 for it to become zero. Hence the y-intercept will be 2·12 less than the last value in the table:

1 - 2·12 = -23 . . . the y-intercept

The figures in the picture are similar to each other find the value of x

alisha [4.7K]

Answer:

x = 7

Step-by-step explanation:

Similar figures have sides that are proportional. Setting up a proportion for the sides of the figures will help solve for 'x':

$\frac{small}{large}=\frac{3}{6}=\frac{(x-3)}{(x+1)}$

Cross-multiply: 3(x + 1) = 6(x - 3)

Distribute: 3x + 3 = 6x - 18

Combine like terms: 21 = 3x

Solve for 'x': x = 7

Answer:

B. 200 doses

Step-by-step explanation:

Given,

1 dose is required for 100 mg,

Since, 1 mg = 0.001 g,

⇒ 100 mg = 0.1 g

⇒ 1 dost is required for 0.1 g,

Thus, the ratio of doses and quantity ( in gram ) is $\frac{1}{0.1}=10$

Let x be the doses required for 20 grams,

So, the ratio of doses and quantity is $\frac{x}{20}$

$\implies \frac{x}{20}=10$

$\implies x=200$

Hence, 200 doses can be obtained from 20 grams of the drug.

Option 'B' is correct.

If pq=3 and pq+rs=5, then 3+rs=5 is an example of the _________.

Mrrafil [7]

<span>This is an example of the substitution property of equality, meaning that if pq = 3, you may substitute 3 for pq in another related equation. So if pq+rs=5 is true, then 3+rs=5 is true as well.</span>

What is the area of a piece of garden plot 5 yards 2 feet long by 6 yards 1 foot wide? Give your answer in square feet. A. 323 s

Blababa [14]

change yrds to ft

5yds = 5*3 = 15 ft

5yds 2 ft = 15ft + 2ft = 17 ft

6yds = 6 * 3 = 18 ft

6 yds 1 ft = 18 + 1

19 ft

A = l * w

A = 17* 19

A = 323 ft^2

Choice A
