A glass is full. Then 70cm of orange juice is poured in.
The glass is now i full. What is the total volume of the glass?
Answer:
392cm³
Step-by-step explanation:
First, we need to find what fraction of the whole volume was just added. We started with 4/7 and ended up with 3/4, so we can take the difference of the two to find the fractional part added:
[tex]\frac{3}{4}-\frac{4}{7} =\\\\\frac{21}{28}-\frac{16}{28} =\frac{5}{28}[/tex]
So, that 70cm³ represents 5/28 of the whole glass. If 70cm³ is 5/28 of the glass's volume, then 70/5 = 14cm³ must be 1/28 of the volume. From here, we can simply multiply 14 by 28 to find the total volume, all 28/28 of it:
14 · 28 = 392cm²
Find the value of x
11x-1+20x-3=151
Answer:
x = 5
Step-by-step explanation:
11x - 4 + 20x = 151
31x - 4 = 151
31x - 4 + 4 = 151 +4
31x = 155
31x/31 = 155/31
x=5

the sum of a number and 2 is no more than 6 or no less than 10
i need to define the variable , write a compound inequality and solve.
Answer:
a. x + 2 ≤ 6 or x + 2 ≥ 10 b. x ≤ 4 or x ≥ 8
Step-by-step explanation:
a. Write a compound inequality
Let x be the number.
Since x + 2 is no more than 6 then x + 2 ≤ 6 and x + 2 is no less than 10 then x + 2 ≥ 10
So, the compound inequality is x + 2 ≤ 6 or x + 2 ≥ 10
b. Solve the inequality
Solving each inequality, we have,
x + 2 ≤ 6
x ≤ 6 - 2
x ≤ 4
x + 2 ≥ 10
x ≥ 10 - 2
x ≥ 8
So, x ≤ 4 or x ≥ 8

Step-by-step explanation:
12(x-2)+3x=12(x+6)+2
12x - 25 + 3x = 12x + 72 +2
15x-24=12x+74
15x=12x+98
3x=98
x=32.666
Hope this helped!
Answer:
x=32.67
Step-by-step explanation:
12(x-2)+3x=12(x+6)+2
12x-24+3x=12x+72+2
simplify
15x-24=12x+74
15x-12x-24=12x-12x+74
3x-24=74
3x-24+24=74+24
3x=98
x=32.67

Two similar rectangles have a scale factor of 3:2. The perimeter of the small rectangle is 50 feet. What is the perimeter of the large rectangle measured in feet?
Answer: The perimeter of the large rectangle measured 75 feet.
Step-by-step explanation:
For two similar rectangles,
[tex]\dfrac{\text{Perimeter of image }}{\text{Perimeter of pre-image }}=\dfrac{3}{2}[/tex]
The perimeter of the small rectangle is 50 feet.
Given ratio between two similar rectangles: 3:2
So,
[tex]\dfrac{\text{perimeter of large rectangle}}{\text{perimeter of small rectangle}}=\dfrac{3}{2}\\\\\Rightarrow\ \dfrac{\text{perimeter of large rectangle}}{50}=\dfrac{3}{2}\\\\\Rightarrow\ \text{Perimeter of large rectangle} =\dfrac{3}{2}\times50\\\\\Rightarrow\ \text{Perimeter of large rectangle} =75[/tex]
Hence, the perimeter of the large rectangle measured 75 feet.
The perimeter of a rectangle is the sum of the dimension of the rectangle
The perimeter of the larger rectangle is 75 feetThe ratio of the side length is given as:
[tex]Ratio = 3 : 2[/tex]
Represent the perimeters of both rectangles with
P1 and P2.
So, we have:
[tex]P1 : P2 = 3 : 2[/tex]
The smaller rectangle has a perimeter of 50 feet.
So, we have:
[tex]P1 : 50 = 3 : 2[/tex]
Express as fraction
[tex]\frac{P1 }{ 50 }= \frac 3 2[/tex]
Multiply both sides by 50
[tex]P1= \frac 3 2 \times 50[/tex]
[tex]P1= 75[/tex]
Hence, the perimeter of the larger rectangle is 75 feet
