How is the ratio of crushed tomatoes to tomato paste different from the ratio of tomato paste to crushed tomatoes?
Answer and explanation:
The ratio 1:2 is different from the ratio 2:1. The ratio 1:2(one to two) means a comparison of two sizes; the ratio of one part of that thing to the ratio of two parts of that thing. Likewise, the ratio 2:1 is the comparison of two parts of a thing to the ratio of one part of the thing. For the ratio 2:1, we could say for example that for every two crushed tomatoes there is one tomato paste.

The product of three and a number increased by 7 is 16
Answer:
Equation: 3x + 7 = 16
Unknown Number: 3
Step-by-step explanation:
You must first develop an equation representing this problem:
3x + 7 = 16
Then, you can solve for the unknown number.
3x + 7 = 16
3x = 9
x = 3

Given:
The graphs of two parabolas.
To find:
The equation of the quadratic function with given graphs.
Solution:
(a)
The factor form of a parabola is
[tex]y=a(x-b)(x-c)[/tex]
Where, a is a constant, b and c are x-intercepts.
From the graph (a) it is clear that the graph intersect the x-axis at -1 and 3. So, b=-1 and c=3.
[tex]y=a(x-(-1))(x-3)[/tex]
[tex]y=a(x+1)(x-3)[/tex] ...(i)
Put x=0 and y=3 because the y-intercept is (0,3).
[tex]3=a(0+1)(0-3)[/tex]
[tex]3=-3a[/tex]
[tex]\dfrac{3}{-3}=a[/tex]
[tex]-1=a[/tex]
Putting a=-1 in (i), we get
[tex]y=-1(x+1)(x-3)[/tex]
[tex]y=-(x+1)(x-3)[/tex]
Therefore, the equation of the parabola is [tex]y=-(x+1)(x-3)[/tex].
(b)
The vertex form of a parabola is
[tex]y=a(x-h)^2+k[/tex]
Where, a is a constant and (h,k) is vertex.
From the the graph (b), it is clear that the vertex of the of the parabola is at point (2,0) and y-axis is (0,8). So, h=2, k=0.
[tex]y=a(x-2)^2+0[/tex]
[tex]y=a(x-2)^2[/tex] ...(ii)
Put x=0 and y=8 because the y-intercept is (0,8).
[tex]8=a(0-2)^2[/tex]
[tex]8=4a[/tex]
[tex]\dfrac{8}{4}=a[/tex]
[tex]2=a[/tex]
Putting a=2 in (ii), we get
[tex]y=2(x-2)^2[/tex]
Therefore, the equation of the parabola is [tex]y=2(x-2)^2[/tex].
A map has the scale of 1 inch = 50 miles. if two cities are 1 inch apart on the map how many miles separate the cities?
Answer: 175
Step-by-step explanation:
To determine the actual distance using the map scale of 1 inch = 50 miles, you would multiply the number of inches shown on the map by 50.
For this problem: 3 1/2 • 50 = 7/2 • 50 = 175 miles
The two cities are 175 miles apart.

by pythagorus :
x^2 = 8^2 + 6^2 x^2 = 64 + 36x = root 100x = 10Hopkins has a 1 meter wire using to make clocks. Each fourth meter is marked off and divided into 5 smaller equal lengths.
Complete question :
Mr. Hopkins has a 1 meter wire he is using to make clocks. Each fourth meter is marked off with 5 smaller equal lengths. If Mr. Hopkins bends the wire at ¾ meter, what fraction of the marks is that?
Answer:
15 th ; 15/20
Step-by-step explanation:
Length of wire = 1 m
Number of fourth length possible = 1 ÷ 1/4 = 1 * 4/1 = 4
Each fourth length divided into 5 equal sizes :
Hence. Total number of equal spaced division :
5 * 4 = 20
If wire is bent at 3/4 meter :
Fraction of the mark
3/ 4 of 20
3/4 * 20
(3 * 20) / 4
60 / 4
= 15th
= 15/ 20
indica a que numero decimal coresponde a esta fraccion
6/100
Answer: 0.06
because 100 has two zeros, the move the number of zeros to the left so the answer is 0.06

Lance put $40,000 into a bank account that pays 3% interest every 4 months. How much money will Lance have after 5 years?
Answer:
$600,000
Step-by-step explanation:
interest = 3/100 × 40,000 = $1200
4 months = 1/3 years
[tex]p = \frac{100 \times i}{rt} = \frac{100 \times 1200}{3 \times \frac{1}{3} } = 120000[/tex]
$120,000 in 1 year
5years, 120,000×5 = $600,000
Answer:
here u go
Step-by-step explanation:
$600,000
Step-by-step explanation:
interest = 3/100 × 40,000 = $1200

6x^3+x
Answer:
x(6x^2+1)
Step-by-step explanation:
To factor an equation, we have to take out the greatest common factor of both terms. In this case, that term would be x. Then we can out x outside of the parantheses and your distributive property to rewrite this equation.
Substitute the value n = 4 in the expressions
2n
n + 2
3(n+4)
Step-by-step explanation:
Given n = 4
2n = 2* 4= 8
n + 2 = 4 + 2 = 6
3(n + 4) = 3( 4 + 4) = 3 * 8 = 24

Which equation can we use to find the equal volume of concrete in cubic feet darlin' needs for the staircase
Answer:
The equation required to find the volume of concrete is:
L X W X H.
Step-by-step explanation:
L = Lenght
W = Width
H = Height
To calculate the required volume for concrete, you'd need to multiply the measures of all the dimensions together such as the lenght and the breath (which gives you the Area) and the thickness or height of the staircase.
If the calculation is being expressed in Feet, the answer will also be expressed as Volume of concrete in Cubic feet.

Simplify 12cm to 2.5mm
Given:
12cm to 2.5mm
To find:
The simplified for of given statement.
Solution:
We know that,
1 cm = 10 mm
12 cm =120mm
We have,
12cm to 2.5mm
It can be written as
[tex]\dfrac{12\ cm}{2.5\ mm}=\dfrac{120\ mm}{2.5 mm}[/tex]
[tex]\dfrac{12\ cm}{2.5\ mm}=\dfrac{120}{2.5}[/tex]
[tex]\dfrac{12\ cm}{2.5\ mm}=48[/tex]
Therefore, the value of 12 cm to 2.5 mm is 48 or 48:1.

Smart ppl please help meee
Answer:
The reason why the area is 2a+3a+4a is because ax2=2a ax3=3a and ax4=4a know we know each segment so after that you add the segments to get the are equation which is 2a+3a+4a.
The reason why the area is also (2+3+4)a is because you just factored the orginial equation and if you use the distributive property they equal the same.
