B)about 36
C)$ 0.19 (rounded) per potato
The Peters will cost to buy 22 potatoes is$4.13 , Fernando can buy 37 potatoes for $7 and the unit cost per potato is $0.1875.
How to form an equation?
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Given that
8 potatoes cost $1.50
8 potatoes ⇔ $1.50
1 potato ⇔ $(1.50/8)
a) →
22 potatoes will cost 22 × $(1.50/8) = $4.13
b) →
8 potatoes ⇔ $1.50
$1 ⇔ 5.33 photos
By multiply 7
$7 ⇔ 37.33
Si Fernando can buy 37 potatoes.
c) →
1 potato ⇔ $(1.50/8)
1 potato ⇔ $0.1875
Hence "The Peters will cost to buy 22 potatoes is $4.13, Fernando can buy 37 potatoes for $7 and the unit cost per potato is $0.1875".

If g(x)=2/3(x-4)^2, find x when g(x)=8
8 = 2/3(x - 4)^2
Take the sqrt of both sides
Sqrt(8) = 2/3(x - 4)
Divide each side by 2/3
(3 * sqrt(2)) = x - 4
Add 4 to both sides
(3 * sqrt(2)) + 4 = x

Solve the equation 34 - (x + 8) = 6x-2
Answer:
x = 4
Step-by-step explanation:
To solve the equation, we would have to solve for the variable x.
34 - (x + 8) = 6x - 2
Remove the parentheses.
34 - x - 8 = 6x - 2
Add 2 to both sides and combine like terms.
28 - x = 6x
Add x to both sides.
28 = 7x
Swap sides.
7x = 28
Divide both sides by 7.
x = 4
So the solution to the equation would be x = 4

A. 14 m2
O
B. 18 m2
O
C. 21 m2
O
D. 35 m2
Answer:
Area of the trapezoid = 18 m²
Step-by-step explanation:
Formula to calculate the area of a trapezoid is,
Area of a trapezoid = [tex]\frac{1}{2}(b_1+b_2)h[/tex]
Where [tex]b_1[/tex] and [tex]b_2[/tex] are the parallel sides of the trapezoid
And h = distance between the parallel sides
From the figure attached,
[tex]b_1[/tex] = 5 m
[tex]b_2[/tex] = (6 + 1) = 7 m
h = 3 m
By substituting these values in the formula,
Area of a trapezoid = [tex]\frac{1}{2}(5+7)3[/tex]
= 6 × 3
= 18 m²
Therefore, area of the given trapezoid is 18 m².
Chelsea wants to buy a new iPhone that costs $324. She
has already saved $56. If she can save $20 a week, how
many weeks will it take for her to be able to purchase the
iPhone?
Answer:
14 full weeks.
Step-by-step explanation:
The phone costs $324 and she saved $56, so we subtract $56 from $324.
$324 - $56 = $268
She saves $20 each week so we divide $268 by $20 to get the number of weeks.
$268/20 = 13.4
It will take 13.4 weeks, but we have to round up because at 13 weeks she won't have enough saved. So 14 full weeks.
If your expression contains square roots, during which step of PEMDAS do you solve them? A parentheses B exponents C multiplication D division
Answer:
B
Step-by-step explanation:
Roots can also be represented as indicies (exponents) and thus should be treated like them. For example, square root could also be written as exponent 1/2.
When dealing with square roots in a equation, PEMDAS calls for this to be solved when you do B. Exponents
The root of a number is that number expressed exponentially by the root in inverted form. In other words, when you take something to its square root, you would be taking it to the inverse of 2 which is 1/2.
For instance:
√4 = 2 = 4¹/²
This means that you can then solve the square root when you deal with exponents which is the second step.
In conclusion, if you see an expression with square roots, PEMDAS allows you to solve it as an exponent.

1. A student in an algebra course has test scores of 75, 82, 71, and 84. What score on the next test will raise the student’s average to 80?
Hey there! I'm happy to help!
We have 5 numbers that will give us an average score of 80.
75,82,71,84,x
What we do is add these all up and divide by 5 to get 80. Let's go backwards to find x.
We multiply by 5.
80(5)=400
We subtract all of the numbers except for x.
400-75-82-71-84=88
Therefore, the score on the next test has to be 88 to have the student's average be 80.

a machinist can produce 114 parts in 6 minutes. at this rate, how many parts can the machinist produce in 15 minutes
Answer:
285!
Step-by-step explanation:
First you have to find out how may parts are produced in a single minute.
We know that 114 parts are produced in 6 minutes so to find how may parts are made in one minute divide 114 by 6 and get an answer of 19
114÷6=19
Now to find how may parts are produced in 15 minutes multiply 19 (number of parts produdced in one minute) by 15 and get an answer of 285!
19×15=285

Where would the plane STV intersect plane Z?
Answer:
Plane Z or plane VTX.
Step-by-step explanation:
From the picture attached,
ST pierces the plane at a point T.
That means line ST is perpendicular to the horizontal plane Z or plane VTX.
Since, S is a point lying on line ST it will not lie on the vertical plane VTX Or plane Z.
Therefore, point S is not contained in the plane Z.

ABC is an isosceles triangle. Solve for x. In your final answer, include all of the necessary calculations. You may include a sketch as part of your calculations.
Answer:
x= 105
Step-by-step explanation:
Let the unknown angle at the base be y. We know the base angles of an isosceles triangle are the same
The sum of the angles of the triangles are
30 + y +y = 180
30 + 2y = 180
2y = 180-30
2y = 150
y = 75
We know that x+y = 180 since it forms a straight line
x+75 =180
x = 180-75
x = 105
Answer:The abc conjecture It is stated in terms of three positive integers, a, b and c (hence the name) that are relatively prime and satisfy a + b = c. So a conjecture is like an educated guess.

As of July 2012, the world record for the 100 meter dash is held by Usain Bolt of Jamaica, who finished such a race in 9.572 seconds in Berlin, Germany, on August 16, 2009. Calculate Bolt’s average race speed in miles per hour. Show all work. Use a conversion rate of 1 mi ~ 1.609 km. Round to three decimal places.
Answer:
v = 23.370 mph
Step-by-step explanation:
It is given that,
The world record for the 100 meter dash is finished in 9.572 seconds in Berlin. We need to find the Bolt’s average race speed in miles per hour.
We know that,
1 mile = 1.609 km
or
1 mile = 1609.34 m
⇒ 100 m = 0.0621 miles
1 hour = 3600 seconds
⇒ 1 second = (1/3600) hour
Average speed = distance/time
So,
[tex]v=\dfrac{\dfrac{100}{1609.34 }\text{miles}}{\dfrac{9.572}{3600}\ \text{hour}}\\\\v=23.36963\ \text{mph}[/tex]
or
v = 23.370 mph
Hence, Bolt’s average race speed is 23.370 mph.
