This is the concept of algebra. The value of x three times less than the value of 45-10x will be as follows;
The value of x three times is:
3x
subtracting 45-10x we get:
3x-(45-10x)
3x+10x-45
13x-45
the answer is:
13x-45
The volume of the first figure: 904.78 m^3
the volume of the second figure: 113.1 m^3
Difference: 904.78-113.1= 791.68
Answer:
403.75
Step-by-step explanation:
we can write the following equation
.75m+145=price
we just need to plug in 345 for m
.75*345+145=price
put this into a calculator and get 403.75
Answer:
2 notebooks
Step-by-step explanation:
I understand you already figured out that it was 3 notebooks, but when I calculated it, I believe he could only buy 2...
Personally, I would show my work by first doing the calculation: 2.75[1 notebook price]+ (3[pens/pencils per notebook]*1.10[pen/pencil cost])= $9.075 per notebook and 3 pens
If you then showed that you multiplied 9.075 by 2... you would get $18.15 which is the closest you could get to his limit of $22 without going over
If we applied your answer of 3 notebooks, then the total would be $27.225 which goes over the money limit.
Hope I helped!
Answer:
4.33 : 6.49
Step-by-step explanation:
Given endpoints as A(-7,-2) and (2,4) find the length of the segment
d=√ (x₂-x₁) + (y₂-y₁)²
d=√ (2--7)² + (4--2)²
d=√ 9² + 6²
d= √ 81 +36
d=√117 =10.82
The partition is at (-3.4,0.4)
The length from A to the partition will be
A(-7,-2) (-3.4,0.4)
√ (-3.4--7)² + (0.4--2)²
√ 3.6²+2.4²
√18.72 = 4.33
Length of segment from partition to end point B
(-3.4,0.4) , B(2,4)
√(2--3.4)²+(4-0.4)²
√ 5.4² + 3.6²
√42.12
=6.49
The ration that results from the partition of the segment is;
4.33 : 6.49
