Answer:

You would pay $0.28 for 1 oz of bag of cheese

Step-by-step explanation:

$1.99 (price for 7.2 oz) ÷ 7.2 oz (how much the bag weighs) = $0.28 (rounded since the original number was: 0.2763888)

1) Irene places a mirror on the ground 24ft from base of an oak tree.she walks backward until she can see the top of the tree in

zimovet [89]

<u>Answer:</u>

Oak tree is 33 ft tall.

<u>Step-by-step explanation:</u>

We know that Irene places a mirror on the ground and walks backwards such that the mirror is in between her and the oak tree (as shown in the attached picture).

Given the distance of Irene's eyes from ground, distance between oak tree and mirror and distance between mirror and Irene, we are to find the height of the tree.

For this, we will use the ratio method:

$\frac{T}{24} =\frac{5.5}{4}$

T = 33 ft

Please need help from math experts!!!! Struggling so hard…

Alenkinab [10]

Answer:

Step-by-step explanation:

A(10,10) B(b,10b)

ax-2y=30

$a)\\a(10)-2(10)=30\\10a-20=30\\10a-20+20=30+20\\10a=50$

Divide both parts of the equation by 10:

a=5

Hence,

5x-2y=30

5(b)-2(10b)=30

5b-20b=30

-15b=30

Divide both parts of the equation by -15:

b=-2

Thus,

a=5 b=-2

$b)\\A(10,10)\ \ \ \ \ \ B(-2,-20)\\ \displaystyle\\C(x_C,y_C)=(\frac{10+(-2)}{2} ,\frac{10+(-20)}{2} )\\\\C(x_C,y_C)=(\frac{10-2}{2},\frac{10-20}{2} )\\\\C(x_C,y_C)=(\frac{8}{2} ,\frac{-10}{2})\\\\C(x_C,y_C)=(4,-5)\\Hence,\ C(4,-5)$

$5x-2y=30\\5x-2y+2y=30+2y\\5x=30+2y\\5x-30=30-30+2y\\5x-30=2y\\$

Divide both parts of the equation by 2:

2.5x-15=y

$c)\\y=2.5x-15$

The equation of the perpendiqular bisector

$\boxed {y=-\frac{x}{k} +b}$

Hence,

$\displaystyle\\y=-\frac{x}{2.5}-15 \\\\y=-0.4x-15$

Dory is building a wall around her garden. It has taken 45 minutes and she is 75% done. What is the total time that will take he

Inessa [10]

So it's easier to calculate if you figure out how much time it took her to finish 25% of the wall. Since it took her 45 minutes to do 75%, it took her 15 minutes to do 25%. Then you just multiply.

Therefore, it takes her 60 minutes to finish building her wall.
