A recipe for beef fajitas uses 5 pounds of beef to make 20 meals. How many pounds of beef are needed to make 80 meals?
Answer: 0.25 pound of beef are needed to make 80 meals.
Step-by-step explanation:
Given : A recipe for beef fajitas uses 5 pounds of beef to make 20 meals.
Then the of beef required for 1 mesal = ( 5 pounds) ÷ 20
= [tex]\dfrac{5}{20}[/tex] pound
[tex]=\dfrac{1}{4} [\text{Divide numerator and denominator}][/tex]
=0.25 pound
Hence, 0.25 pound of beef are needed to make 80 meals.

Step-by-step explanation:
5% interest on $5,000 for one year would be $250
the total amount wlike be $5250 but the question seems to only ask for the interest
convert 5% to a decimal to multiply to find interest
0.05•5000 gives us the interest for the year
hope this helps <3

Hence, Jessica needs 2 cases of 12 girls scout cookies plus 2 extra boxes
Can someone plz help me with this??
Answer:
it's the second choice (3=3)
Answer:
y = - x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (3, 1)
m = [tex]\frac{1-3}{3-1}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1 , then
y = - x + c ← is the partial equation
To find c substitute (1, 3 ) into the partial equation
3 = - 1 + c ⇒ c = 3 + 1 = 4
y = - x + 4 ← equation of line

Pierce removes the plug from a trough to drain the water. The volume, in gallons, in the trough after it has been unplugged can be modeled by the expression 10x2 −17x + 3, where x is the time in minutes. Choose the appropriate form of the expression that would reveal the time in minutes when the trough is empty.
10(x − 3)2 − 1
10(x − 1)2 − 3
(5x − 1)(2x − 3)
10(0)2 − 17(0) + 3
Answer:
(5x - 1)(2x - 3)
10x^2 - 17 + 3 = (5x - 1)(2x - 3)
Answer:
C.(5x − 1)(2x − 3)

Step-by-step explanation:
X=
(-6x+125) (11x + 6)
9514 1404 393
Answer:
x = 7
Step-by-step explanation:
The base angles of an isosceles triangle are congruent, so ...
11x +6 = -6x +125
17x = 119 . . . . . . . . . add 6x-6 to both sides
x = 7 . . . . . . . . divide by 17
y = 8/x

When a standard die is rolled, find the probability of getting a. 5 b. A number larger than 2 c. An odd number.
Answer:
P(getting a 5)=[tex]\frac{1}{6}[/tex]
P(number larger than 2)=[tex]\frac{2}{3}[/tex]
P(numbers which are odd) =[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
When a standard die is rolled, we get sample space as {1,2,3,4,5,6}
So, let's use formula
P(E)=[tex]\frac{outcomes favorable to event E}{Total number of outcomes}[/tex]
For part A:
Event is getting a 5.
So, out of 6 samples , we get one 5 as outcome
So,
P(getting a 5)=[tex]\frac{1}{6}[/tex]
For part B:
The numbers larger than 2 are {3,4,5,6}
So, p(number larger than 2)=[tex]\frac{4}{6} =\frac{2}{3}[/tex]
P(number larger than 2)=[tex]\frac{2}{3}[/tex]
For part C:
The numbers which are odd are {1,3,5}
So, p(numbers which are odd)=[tex]\frac{3}{6 } =\frac{1}{2}[/tex]
P(numbers which are odd) =[tex]\frac{1}{2}[/tex]

All I can say is that the slope is 1/5
Answer:
Same thing as my last answer, but with a different graph.
Step-by-step explanation:
You know a point. X = 10 and y=40
by this definition you can without the hassle, know to divide both values by 10 to get the lowest numbers possible. y= 4x
using that, data of the slope, try and answer the question (follow my guides from last time ;) )
Hope This Helps :)

55% of students say chocolate is their favorite ice cream flavor. If 88 students said chocolate is their favorite ice cream flavor, how many total students were surveyed?
Answer:
160
Step-by-step explanation:
total = 100%
we know,
55 % of total = 88
or, 55/100 * total = 88
so total = 160
