Answer:

Y-intercept or b = 2.5

X-intercept = 3.5

Step-by-step explanation:

The y-intercept is where the graph intersects on the y-axis, where x=0.

Thus, the y-intercept or b = 2.5.

The x-intercept is where the graph intersects on the x-axis, where y=0.

Thus, the x-intercept = 3.5.

Y-intercept = 2.5

x-intercept = 3.5

Pretty much the same as whoever answered before me.

A $ 140 jacket is on sale for 35% off. what is the sale price of the jacket

zvonat [6]

Answer:

$91

If a jacket is on sale for 35% off, that means that the price of the jacket is % of its original price.

We can find 65% of 140 by making 65% into a decimal - 0.65, then multiply it by 140.

Hope this helped!

slega [8]

Answer:

a) $83.3\ lb/in^2$

b) $12000\ lb/ft^2$

Step-by-step explanation:

Given : A weight of 18,000 lb is supported on a rectangular base plate that is 9 in. wide and 2 ft long. The base plate rests on a concrete slab.

To find : Determine the stress that the base plate exerts on the concrete slab. Express your answer in units of (a) lb/in². and (b) lb/ft².

Solution :

a) A rectangular base plate that is 9 in. wide and 2 ft long.

Converting ft into inches,

1 feet = 12 inch

2 feet = 2×12= 24 inch

The area of the rectangular base is $A=l\times b$

$A_1=24\times 9$

$A_1=216\ in^2$

The weight is W=18,000 lb.

The stress that the base plate exerts on the concrete slab is given by,

$S=\frac{W}{A_1}$

$S=\frac{18000\ lb}{216\ in^2}$

$S=83.3\ lb/in^2$

b) A rectangular base plate that is 9 in. wide and 2 ft long.

Converting inches into ft,

1 inch = $\frac{1}{12}\ ft$

9 feet = $\frac{9}{12}=0.75\ ft$

The area of the rectangular base is $A=l\times b$

$A_2=2\times 0.75$

$A_2=1.5\ ft^2$

The weight is W=18,000 lb.

The stress that the base plate exerts on the concrete slab is given by,

$S=\frac{W}{A_2}$

$S=\frac{18000\ lb}{1.5\ ft^2}$

$S=12000\ lb/ft^2$

P is the centroid of triangle ABC. AE = 21, CD = 14, and BF = 11. What is the length of AP?

Rus_ich [418]

Answer

$AP=14$

Step by Step Explanation

1) Due to the Centroids Theorem we can say that:

AP=2/3AE

AP=2/3*21

∴AP=14

2) Finally, AE =AP+AE

21=14+7 ⇒21=21 True

AP =2PE verifies the Theorem too.

So, the size is 14 .

$AP=14\:u$
