The information we have is:
So we can find that two coordinates are ( -2,-8 ) and ( 3,7 ) so we can use the equation to find the slope so:
So the equation now will be:
So we can replace one coordinate to find b so:
So the final equation is:
Answer:
The area of one of the bases is 0.96 ft²
The area of each lateral rectangular face is 4.8 ft²
The surface area of the paperweight is 6.72 ft²
Step-by-step explanation:
we know that
The surface area of the rectangular prism is equal to
SA=2B+LA
where
B is the area of one of the bases
LA is the lateral area of the prism
<em>Find the area of one of the bases B</em>
B=(0.8)(1.2)=0.96 ft²
<em>Find the lateral area LA</em>
The lateral area is the area of each lateral rectangular face
LA=2[(0.8)(1.2)]+2[(1.2)(1.2)]=4.8 ft²
<em>Find the surface area</em>
SA=2(0.96)+4.8=6.72 ft²
Answer:0.25
Step-by-step explanation: 4/16 can be simplified to 1/4. Think about it like quarters. You need 4 quarters to have one dollar. If you have one quarter it is equal to $0.25.
The total amount of money Christina spent on streaming music service in a year is $36
<h3>How to find the total cost</h3>
- One time payment = $18
- Cost of each song = $1.20
- Number of songs = 15
Total yearly cost = One time payment + Cost of each song(Number of songs)
= 18 + 1.20(15)
= 18 + 18
= $36
Therefore, the total amount of money Christina spent on streaming music service in a year is $36
