Answer:

130lbs

Step-by-step explanation:

52 weeks divided by 4 weeks would mean she buys 13 bags of cat food in the entire year. Each bag weighs 10 pounds so 13 times 10 is 130.

A construction company purchased some equipment costing $300,000. The value of the equipment depreciates

goldfiish [28.3K]

Answer:

$11.9\ years$

Step-by-step explanation:

we know that

The formula to calculate the depreciated value is equal to

$V=P(1-r)^{x}$

where

V is the depreciated value

P is the original value

r is the rate of depreciation in decimal

x is Number of Time Periods

in this problem we have

$P=\$300,000\\r=14\%=14/100=0.14\\V=\$50,000$

substitute the values and solve for x

$50,000=300,000(1-0.14)^{x}$

$(50,000/300,000)=(0.86)^{x}$

$(5/30)=(0.86)^{x}$

Apply log both sides

$log(5/30)=(x)log(0.86)$

$x=log(5/30)/log(0.86)$

$x=11.9\ years$

Since TSQ and QSR are supplementary, they give 180 when summed. TSQ is 150, so QSR must be 30.

Therefore, you have

$\tan(30)=\dfrac{\sin(30)}{\cos(30)}=\dfrac{\frac{1}{2}}{\frac{\sqrt{3}}{2}} = \dfrac{1}{2}\cdot\dfrac{2}{\sqrt{3}}=\dfrac{1}{\sqrt{3}}=\dfrac{\sqrt{3}}{3}$

Acme Company has three identical manufacturing plants, one on the Texas Gulf Coast, one in southern Alabama, and one in Florida.

tino4ka555 [31]

Answer:

Somewhere from $50 million to $100 million

Step-by-step explanation:

Hurricanes usually hit the southernmost states of the USA and considering the fact that all three manufacturing plants are in the southernmost states, it would be reasonable to assume that a single hurricane can wipe out at least one or two since Alabama and Florida are really close to each other and Texas is known to get hurricanes. It usually just depends on where the hurricane occurs.

Find the equation of the line passing through the points A(3,2) and B(6,3)

icang [17]

Answer:

y = $\frac{1}{3} x+1$

Step-by-step explanation:

m = $m = \frac{change in y}{change in x} \\m = \frac{3 - (2)}{6 - (3)}\\m = \frac{1}{3} \\Find the value of b using the equation of a line \\y = mx+b\\y =( \frac{1}{3} )x + b\\2 =( \frac{1}{3} ) * (3) + b\\cancel common factor\\1 + b = 2\\b = 1\\y = \frac{1}{3} x + 1$
