If paralell, slopes are same
perpencular, sloes mutiply to -1

neither is neither

the slopes
y=mx+b
m=slope

ax+by=c
-a/b=sloe

given

y=-2/3x+1
slope=-2/3

2x-3y=-3
slope=-2/-3=2/3

-2/3 and 2/3 aren't equal nor do they multipy to -1

neither
C

(Help with this Please?)
Yakvenalex [24]

Answer:

A) 30 cubes.

B) 30 units³.


Step-by-step explanation:

A) 1. Calculate the volume of the rectangular prism, as following:

Vr=(lenght)(width)(height)

2. You have that:

- The length is: 1^{\frac{1}{2}}ft=1.5ft

- The width is: 1ft

- The heigth is: 2^{\frac{1}{2}}ft=2.5ft

3. Substitute these values into the formula:

Vr=(1.5ft)(1ft)(2.5ft)=3.75ft^{3}

4. The volume of one cube is:

Vc=side^{3}

5. The length of one side is: \frac{1}{2}ft=0.5ft

6. Substitute this value into the formula:

Vc=(0.5ft)^{3}=0.125ft^{3}

7. The number of small cubes that can be packed in the rectangular prism is:

cubes=\frac{Vr}{Vc}\\cubes=\frac{3.75ft^{3}}{0.125ft^{3}}\\cubes=30

B) 1. The length, the width and the height of the rectangular prism in term of units cubes is:

Length=\frac{1.5ft}{0.5ft}=3units

Width=\frac{1ft}{0.5ft}=2units

Heigth=\frac{2.5ft}{0.5ft}=5units

2. Therefore, the volume of the rectagular prism in terms of the small cube and a unit cube is:

Vr=(3units)(2units)(5units)=30units^{3}

Mrs. Miller has only $42.50 to spend at walmart. She buys a shirt that costs $29, including tax. She wants to buy some bracelets
pshichka [43]

Answer: 2

Step-by-step explanation: 42.50 is the max she can spend there’s .08 cent per dollar. $29 dollars for the shirt plus tax it’ll be 31.32 now Mrs.Miller is left with 11.18 out of her 42.50. Divide 11.18 by 4.50 because that’s the cost of each bracelet. 4.50 multiplied by 2 equals 9 plus tax it’ll be 9.72. 11.18 she had left minuse the 9.72 she’s left with 1.46
