Using proportions, it is found that there are 16 pinches in one teaspoon.
This question is solved by proportions, using a rule of three.One dash has 2 pinches. One teaspoon is the same as 8 dashes. How many pinches are there in 8 dashes?Hence, the rule of three is:
1 dash - 2 pinches
8 dashes - x pinches
Applying cross multiplication:
[tex]x = 2(8) = 16[/tex]
There are 16 pinches in one teaspoon.

Write the quadratic function in vertex form, then identify the vertex
h(x)=x^2+20x+90
h(x)=
Vertex:
I need this answered ASAP please !
Answer:
vertex = (- 10, - 10 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
h(x) = x² + 20x + 90
add/subtract ( half the coefficient of the x- term )²
h(x) = x² + 2(10)x + 100 - 100 + 90
= (x + 10)² - 10 ← in vertex form
with (h, k ) = (- 10, - 10 )

Write an equation of a line that is parallel to y = x - 7 and passes through the point (-6, -11).
Answer:
y = x - 5
Step-by-step explanation:
Comparing the given y = x - 7 to y = mx + b, we see that the slope is +1.
In y = x + b we replace y with -11 and x with -6 to determine the y-intercept, b:
-11 = -6 + b
Then b must be -5, and so the desired new equation is
y = x - 5

Lana correctly answered 48 of 60 questions on a math exam. What percent of questions did she answer correctly?
Answer:
I think it roughly 66.67%
Step-by-step explanation:
sorry if I'm no help
The percent of questions she answered correctly is 80%.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Given;
Lana correctly answered 48 of 60 questions on a math exam
Now,
=48*100/60
=480/60
=80
Therefore, the percentage will be 80%.

Which points are separated by a distance of 4 units? a. (7,7) (1,7) b. (3,3) (1,3) c. (4,2) (8,2) d. (2,4) (5,4)
Answer:
c
Step-by-step explanation:
with the knowledge that we are comparing the x position we can get the equation |x_1-x_2|=4, then just do the maths
(4,2) (8,2) points are separated by a distance of 4 units.
What is distance formula?The 2D distance formula gives the shortest distance between two points in a two-dimensional plane.
Distance Formula = [tex]\sqrt{(x_{2} -x_{1} )^{2} +(y_{2}-y_{1} )^{2} }[/tex]
Given
Distance of 4 units
Option A:
[tex](x_{1} ,y_{1})=(7,7)[/tex]
[tex](x_{2} ,y_{2})=(1,7)[/tex]
Distance = [tex]\sqrt{(x_{2} -x_{1} )^{2} +(y_{2}-y_{1} )^{2} }[/tex]
= [tex]\sqrt{(1-7)^{2}+(7-7)^{2} } =6[/tex]
Option B:
[tex](x_{1} ,y_{1})=(3,3)[/tex]
[tex](x_{2} ,y_{2})=(1,3)[/tex]
Distance = [tex]\sqrt{(x_{2} -x_{1} )^{2} +(y_{2}-y_{1} )^{2} }[/tex]
= [tex]\sqrt{(1-3)^{2}+(3-3)^{2} } =2[/tex]
Option C:
[tex](x_{1} ,y_{1})=(4,2)[/tex]
[tex](x_{2} ,y_{2})=(8,2)[/tex]
Distance = [tex]\sqrt{(x_{2} -x_{1} )^{2} +(y_{2}-y_{1} )^{2} }[/tex]
= [tex]\sqrt{(8-4)^{2}+(2-2)^{2} } =4[/tex]
Option C is correct.
Option D:
[tex](x_{1} ,y_{1})=(2,4)[/tex]
[tex](x_{2} ,y_{2})=(5,4)[/tex]
Distance = [tex]\sqrt{(x_{2} -x_{1} )^{2} +(y_{2}-y_{1} )^{2} }[/tex]
= [tex]\sqrt{(5-2)^{2}+(4-4)^{2} } =3[/tex]
Hence, (4,2) (8,2) points are separated by a distance of 4 units.

Len bought 12.3 ounces of cashews and 15.2 ounces of almonds.
He calculates that if he and four friends share all the nuts equally, each person will receive 5.1 ounces of nuts.
Is his answer reasonable? Use 3-5 complete sentences to explain why or why not.
Answer:A manufacturer produces nuts and bolts. It takes 1 hour of work on machine A and 3 hours on machine B to produce a package of nuts. It takes 3 hours on machine A and 1 hour on machine B to produce a package of bolts. He earns a profit of Rsl7.50
Step-by-step explanation:
Answer:
Lens answer is not reasonable because if you do the math she will be able to share 6.875 ounces. I know this because you can add 12.3 and 15.2 to get 27.5. If you divide 27.5 by 4 you get 6.875.

What is 0.612 repeating (meaning the repeating line is over 612) as a fraction
Answer:
[tex]\frac{612}{999}[/tex]
Step-by-step explanation:
To convert repeating decimals to fractions, you take the numbers that are repeating, in this case 612, and you see how many numbers are repeating. Here we have 3 numbers repeating and so you would divide 612 by 3 9's meaning 999. So 0.612 repeating is equal to [tex]\frac{612}{999}[/tex]. To make sure the answer is right, you can divide the numbers in a calculator to make sure you get the correct decimal.

Find the location of A' given that A is (7, 1).
Translate 1 unit left.
The location of A' is ____
Answer:
We conclude that the location of A' is: A'(6, 1)
Step-by-step explanation:
Given
A(7, 1)To determine:
The location of A'
Translation Rule:
As we have to translate 1 unit left, meaning we need to subtract 1 unit from the x-coordinate of point A(7, 1) to determine the location of A'.
In other words, the translation rule is:
A(x, y) → A'(x-1, y)
as
A(7, 1)
so
A(7, 1) → A'(7-1, 1) = A'(6, 1)
Therefore, we conclude that the location of A' is: A'(6, 1)
