Nick is making cookies the recipe requires 2 1/3 cup of flour and 1/6 teaspoons of salt. Nick wants to make the recipe using 1 cup of flour. To maintain the ratio, how much salt is required when 1 cup of flour is used?
Answer:
1 / 14 tsp salt
(1 over 14)
Step-by-step explanation:
Let's set the scale factor as x.
So,
2 1/3 * x = 1
Divide both sides by 2 1/3, which is equal to 7/3
x = 1 / (7/3)
x = 3 / 7
So, amount of salt would be written as:
(1/6) * (3/7) =
(1/2) * (1/7) =
1 / 14 tsp salt
Solving each equation:
6(-6x+3)=5(1-7x)
Answer x=-2.6
Step-by-step explanation:
6(-6x+3)=5(1-7x)
-36x+18=5-35x
-36x+13=-35x
-5x=13
13/ -5x
x=-2.6
An adult elephant that is 8 ft tall casts a shadow that is 4 ft long. Find the height of a
statue that casts a 9 ft shadow.
Answer: Hope this helps!
18 ft
Step-by-step explanation: Good luck :)
This question sounds confusing but if you just look at the numbers it is much easier.
Elephant height: 8 ft
Elephant shadow: 4ft
Statue height: ?
Statue shadow: 9ft
As you can see the elephant's height is double the size of the shadow, if you put those as ratios the statues height will also be double its shadow, from there just double 9ft and you will get your answer. 9x2=18ft

Juan and Rita both rode bicycles from the park to Main Street. The graphs below represent the time and distance for each student’s ride. Who rode more slowly? Justify your answer.
Answer:
Juan rode more slowly, Rita's graph is much steaper than Juan's. This means that she went faster and in less time. Juan took longer time and went on a slower pace. That's why I chose Juan.

Erika is painting a rectangular painting. The painting has a length of 12 and a width of 10 inches. Use the Distributive Property to decompose the factor 12. Then find the area of the painting.
Given:
Length of the painting = 12 inches
Width of the painting = 10 inches
To find:
The area of the rectangular painting by using Distributive Property to decompose the factor 12.
Solution:
The area of a rectangle is
[tex]A=length\times width[/tex]
So, the area of the rectangular paining is
[tex]A=12\times 10[/tex]
Using Distributive Property to decompose the factor 12, we get
[tex]A=(10+2)\times 10[/tex]
[tex]A=(10\times 10)+(2\times 10)[/tex]
[tex]A=100+20[/tex]
[tex]A=120[/tex]
Therefore, the area of the rectangular painting is 120 square inches.

10x-2x+12=2(3x+5)+2x
Answer: is this pemdas? if not there are no true solutions
Step-by-step explanation:
hope i helped
Answer:
the answer to 10x-2x+12=2(3x+5)+2x is 2
Step-by-step explanation:
step 1.
Open the brackets by multiplying the valves in the brackets by 2:
10x-2x+12=6x+10+2x
step 2.
Add or subtract the like-terms : x values.
8x+12=8x+10
step 3.
substitute by bringing like terms together:
12-10=8x-8x
2=0
ans =2

Answer:
x = 33
Step-by-step explanation:
Because the parallel lines are intersected by two transversals, some parts of this figure correspond to each other. In order to solve this problem, you need to identify which sides correlate (you can tell they correlate because of the AAA property; if you extend the lines, a triangle with 2 parallel lines intersecting it would be formed, so you would see the three triangles are similar):
9 corresponds to 12
x corresponds to (x + 11)
Now, you need to find the scale factor by dividing 12 by 9:
12 ÷ 9 = 4/3
Since you know the scale factor is 4/3, you can now write and solve an equation:
4/3x = x + 11 (given)
1/3x = 11 (subtract x from both sides)
x = 33 (multiply both sides by 3)

What is the area of this.
The average person's stride lenghth the distance covered by one step is aproximently 2.5 feet long. How many steps would the average person take to travel 50 feet?
Answer: 20 steps
Step-by-step explanation:
From the question, we are informed that the average person's stride length the distance covered by one step is 2.5 feet long.
To know the steps that the average person would take to travel 50 feet, we simply have to divide 50 feet by 2.5 feet. This will be:
= 50 / 2.5
= 20
This means that an individual will take 20 steps to travel 50 feet

Mrs. Aguirre is going to plant a rectangular garden in her rectangular backyard, as
80 ft.
6 f.
(15 ft.
40 ft.
Yard
Garden
75 ft.
What is the approximate area of the garden?
Ft
Answer:
The answer is below
Step-by-step explanation:
From the image attached we can see that the width of the garden is 6 ft. The length of the garden is the slanting side of the triangle (hypotenuse).
Let x be the length of the garden. The height of the triangle = 40 ft - 15 ft = 25 ft.
The base of the triangle = 80 ft - 75 ft = 5 ft.
The length of the garden is gotten using Pythagoras:
x² = 25² + 5²
x² = 650
x = 25.5 ft.
The area of the garden = length * width = 25.5 * 6 = 153 ft²
Hence the approximate area = 160 ft²
