Al-unit by 3-unit rectangle is shown below. What is the area of the shaded rectangle?

frez [133]

Answer: 1.5 square units

The area of the whole rectangle is 3 units. Area is found by multiplying length by width. Only half of the rectangle is shaded, so if you take the whole area of the rectangle, and divide it in half, you get the area of that half rectangle.

By doing this, you divide 3 in half, and get 1.5 square units.

Hope this helps :)

What is the slope-intercept equation of the line containing the points (–5, 22) and (4, 49) ?

vodka [1.7K]

Answer:

$y=3x+37$

Step-by-step explanation:

Determine slope:

$Slope=m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}=\frac{49-22}{4-(-5)}=\frac{27}{4+5}=\frac{27}{9}=3$

Determine y-intercept:

$y=mx+b$

$49=3(4)+b$

$49=12+b$

$37=b$

Final equation:

$y=3x+37$

Given : The Number of Correct Answers = 30

Given : Total Number of Questions = 40

⇒ The Number of Wrong Answers = (40 - 30) = 10

The Ratio of the Number of Correct Answers to Number of Wrong Answers is :

$\mathsf{\implies \frac{30}{10}}$

$\mathsf{\implies 3 : 1}$ (1st Blank)

The Ratio of the Number of Correct Answers to Total Number of Questions is :

$\mathsf{\implies \frac{30}{40}}$

$\mathsf{\implies 3 : 4}$

If there is 100 Questions on the test and the Ratio stayed the same, The Number of Questions he would have answered correctly is :

$\mathsf{\implies \frac{3}{4} \times Total\;Number\;of\;Questions}$

$\mathsf{\implies \frac{3}{4} \times 100}$

$\mathsf{\implies (3 \times 25)}$

$\mathsf{\implies 75}$ (2nd Blank)
